08-14 12:35 - 'BBRRRR Inflation starting to pick up: "prices for older consumers climbed 1.3% last month...compared with 1% for the price index overall' (self.Bitcoin) by /u/100_Jose_Maria_001 removed from /r/Bitcoin within 1967-1977min
U.S. Inflation Is Even Higher for Consumers Who Are Over Age 62 While U.S. consumer prices in July generally rose more than economists expected, the news was somewhat worse for people over 62. A separate Bureau of Labor Statistics index that tracks prices associated with older consumers climbed 1.3% last month from a year earlier, compared with 1% for the consumer price index overall in Wednesday’s inflation report. The agency this month made the data available on its website; previously it was provided only on request. The index shows inflation for decades has been rising at a faster clip for seniors than for the general public. That’s because it assigns higher weights to items -- including medical services and housing -- based on their relative importance to older people. In 1987, Congress directed the BLS to begin calculating a consumer price index for the elderly. The BLS developed the series and reconstructed it back to the early 1980s.
Good comment from user Voogru at businessweek.com about unreasonable critics of deflation:
Man, I lost my cell phone. If I wait six months, I'll be able to get a better cell phone for less, or the cell phone I want now for FIFTY PERCENT LESS. I'm going to go without a cell phone for six months. Said nobody ever. Man, my car broke down. If I wait six months, I'll be able to get a better car for less money. So I'm going to go without transportation for six months. Said nobody ever. Man, I'm out of food. I'm going to wait a few months before buying any food, because by then it will be much cheaper. Said nobody ever.
Check this out: the inDEX. A weighted running bitcoin price index across multiple exchanges. As someone interested in encouraging adoption, very pleased with this; maybe now consumers and merchants dealing in BTC will finally have a stable way to agree on prices...
Is a Consumer Price Index for Bitcoin too early? Anyone working on it?
I searched for this and found this year old post in Bitcointalk. It may not be necessary right now, but I think it would be very interesting (and educational). And it could be necessary soon if the value of the dollar moves significantly which isn't unthinkable. I'm not an economist, nor would I call myself an economics enthusiast/geek, so I don't even know how difficult it would be to get a CPI. Would a Bitcoin CPI involve a new market basket of goods? Or would it use a basket of goods set by one or more governments? Or perhaps it's really just a matter of using the US CPI that's adjusted to Bitcoin-USD exchange rate. Seems like you could do this using other currencies together with the country's CPI. I don't even know if this makes sense.
For Trading October 27th Housing Numbers Missed COVID, COVID, COVID! Today’s market could have been worse, but I’m not sure how! Prices weakened overnight and then the news only got uglier as the morning progressed. Housing data took a turn for the worse and the selloff just accelerated with the DJIA hitting the low -965 around 1:45, but the bounce was nothing to write home about. We finished -650.19 (2.29%), NASDAQ -189.34 (1.64%), S&P 500 -64.42 (1.8%), the Russell -35.29 (2.15%) and the DJ Transports -275.32 (2.32%) the worst index, but not by enough to make a difference. Housing numbers (new home sales) was not only a disappointment on a month/month basis, but we also had a meaningful restatement of last month’s number from 1,011,000 to 994,000. This month we were expecting 1,022,000 and got 959,000. Tomorrow we have Durable goods, Consumer confidence, NAHB housing prices and Case-Shiller for August. Our “open forum” on Discord, which allows you to interact with subscribers and others to allow direct questions and chart opinions on just about any stock, continues to grow with more participants every day.

It’s a great place to share ideas and gain some insights, and we’ve grown to almost 3000 members. Last week’s interview with Joe Moscato, CEO of GNBT is available today at https://youtu.be/rJBtqC75g3A It’s a great story and this stock (I believe) won’t stay at these levels once there is a wider understanding of what this company actually has going for it!!

Hello visitors and subscribers of scams! Here you will find a master list of common (and uncommon) scams that you may encounter online or in real life. Thank you to the many contributors who helped create this thread!
If you know of a scam that is not covered here, write a comment and it will be added to the next edition.
Caller ID spoofing It is very easy for anyone to make a phone call while having any number show up on the caller ID of the person receiving the phone call. Receiving a phone call from a certain number does not mean that the person/company who owns that number has actually called you. Email spoofing The "from" field of an email can be set by the sender, meaning that you can receive scam emails that look like they are from legitimate addresses. It's important to never click links in emails unless absolutely necessary, for example a password reset link you requested or an account activation link for an account you created. SMS spoofing SMS messages can be spoofed, so be wary of messages that seem to be from your friends or other trusted people.
The most common scams
The fake check scam (Credit to nimble2 for this part) The fake check scam arises from many different situations (for instance, you applied for a job, or you are selling something on a place like Craigslist, or someone wants to purchase goods or services from your business, or you were offered a job as a mystery shopper, you were asked to wrap your car with an advertisement, or you received a check in the mail for no reason), but the bottom line is always something like this:
The scammer sends you a very real looking, but fake, check. Sometimes they'll call it a "cashier's check", a "certified check", or a "verified check".
You deposit the check into your bank account, and within a couple of days your bank makes some or all of the funds available to you. This makes you think that the check is real and the funds have cleared. However, the money appearing in your account is not the same as the check actually clearing. The bank must make the funds available to you before they have cleared the check because that is the law.
For various and often complicated reasons, depending on the specific story line of the scam, the scammer will ask you to send someone some of the money, using services like MoneyGram, Western Union, and Walmart-2-Walmart. Sometimes the scammer will ask for you to purchase gift cards (iTunes, Amazon, Steam, etc) and give them the codes to redeem the gift cards. Some scammers may also give you instructions on how to buy and send them bitcoins.
Within a couple of weeks, though it can take as long as a month, your bank will realize that the check you deposited was fake, and your bank will remove the funds that you deposited into your account and charge you a bounced check fee. If you withdrew any of the money from the fake check, that money will be gone and you will owe that money to the bank. Some posters have even had their bank accounts closed and have been blocked from having another account for 5 years using ChexSystems.
General fraudulent funds scams If somebody is asking you to accept and send out money as a favour or as part of a job, it is a fraudulent funds scam. It does not matter how they pay you, any payment on any service can be fraudulent and will be reversed when it is discovered to be fraudulent. Phone verification code scams Someone will ask you to receive a verification text and then tell you to give them the code. Usually the code will come from Google Voice, or from Craigslist. In the Google version of the scam, your phone number will be used to verify a Google Voice account that the scammer will use to scam people with. In the Craigslist version of the scam, your phone number will be used to verify a Craigslist posting that the scammer will use to scam people. There is also an account takeover version of this scam that will involve the scammer sending a password reset token to your phone number and asking you for it. Bitcoin job scams Bitcoin job scams involve some sort of fraudulent funds transfer, usually a fake check although a fraudulent bank transfer can be used as well. The scammer will send you the fraudulent money and ask you to purchase bitcoins. This is a scam, and you will have zero recourse after you send the scammer bitcoins. Email flooding If you suddenly receive hundreds or thousands of spam emails, usually subscription confirmations, it's very likely that one of your online accounts has been taken over and is being used fraudulently. You should check any of your accounts that has a credit card linked to it, preferably from a computer other than the one you normally use. You should change all of your passwords to unique passwords and you should start using two factor authentication everywhere. Cartel scam You will be threatened by scammers who claim to be affiliated with a cartel. They may send you gory pictures and threaten your life and the lives of your family. Usually the victim will have attempted to contact an escort prior to the scam, but sometimes the scammers target people randomly. If you are targeted by a cartel scam all you need to do is ignore the scammers as their threats are clearly empty. Boss/CEO scam A scammer will impersonate your boss or someone who works at your company and will ask you to run an errand for them, which will usually be purchasing gift cards and sending them the code. Once the scammer has the code, you have no recourse. Employment certification scams You will receive a job offer that is dependent on you completing a course or receiving a certification from a company the scammer tells you about. The scammer operates both websites and the job does not exist. Craigslist fake payment scams Scammers will ask you about your item that you have listed for sale on a site like Craigslist, and will ask to pay you via Paypal. They are scamming you, and the payment in most cases does not actually exist, the email you received was sent by the scammers. In cases where you have received a payment, the scammer can dispute the payment or the payment may be entirely fraudulent. The scammer will then either try to get you to send money to them using the fake funds that they did not send to you, or will ask you to ship the item, usually to a re-shipping facility or a parcel mule. Craigslist Carfax/vehicle history scam You'll encounter a scammer on Craigslist who wants to buy the vehicle you have listed, but they will ask for a VIN report from a random site that they have created and they will expect you to pay for it. Double dip/recovery scammers This is a scam aimed at people who have already fallen for a scam previously. Scammers will reach out to the victim and claim to be able to help the victim recover funds they lost in the scam. General fraudulent funds scams The fake check scam is not the only scam that involves accepting fraudulent/fake funds and purchasing items for scammers. If your job or opportunity involves accepting money and then using that money, it is almost certainly a frauduent funds scam. Even if the payment is through a bank transfer, Paypal, Venmo, Zelle, Interac e-Transfer, etc, it does not matter. Credit card debt scam Fraudsters will offer to pay off your bills, and will do so with fraudulent funds. Sometimes it will be your credit card bill, but it can be any bill that can be paid online. Once they pay it off, they will ask you to send them money or purchase items for them. The fraudulent transaction will be reversed in the future and you will never be able to keep the money. This scam happens on sites like Craigslist, Twitter, Instagram, and also some dating sites, including SeekingArrangement. The parcel mule scam A scammer will contact you with a job opportunity that involves accepting and reshipping packages. The packages are either stolen or fraudulently obtained items, and you will not be paid by the scammer. Here is a news article about a scam victim who fell for this scam and reshipped over 20 packages containing fraudulently acquired goods. The Skype sex scam You're on Facebook and you get a friend request from a cute girl you've never met. She wants to start sexting and trading nudes. She'll ask you to send pictures or videos or get on webcam where she can see you naked with your face in the picture. The scam: There's no girl. You've sent nudes to a guy pretending to be a girl. As soon as he has the pictures he'll demand money and threaten to send the pictures to your friends and family. Sometimes the scammer will upload the video to a porn site or Youtube to show that they are serious. What to do if you are a victim of this scam: You cannot buy silence, you can only rent it. Paying the blackmailer will show them that the information they have is valuable and they will come after you for more money. Let your friends and family know that you were scammed and tell them to ignore friend requests or messages from people they don't know. Also, make sure your privacy settings are locked down and consider deactivating your account. The underage girl scam You're on a dating site or app and you get contacted by a cute girl. She wants to start sexting and trading nudes. Eventually she stops communicating and you get a call from a pissed off guy claiming to be the girl's father, or a police officer, or a private investigator, or something else along those lines. Turns out the girl you were sexting is underage, and her parents want some money for various reasons, such as to pay for a new phone, to pay for therapy, etc. There is, of course, no girl. You were communicating with a scammer. What to do if you are a victim of this scam: Stop picking up the phone when the scammers call. Do not pay them, or they will be after you for more money. Phishing Phishing is when a scammer tries to trick you into giving information to them, such as your password or private financial information. Phishing messages will usually look very similar to official messages, and sometimes they are identical. If you are ever required to login to a different account in order to use a service, you should be incredibly cautious. The blackmail email scam part 5: https://old.reddit.com/Scams/comments/g8jqnthe_blackmail_email_scam_part_5/ PSA: you did not win a giftcard: https://old.reddit.com/Scams/comments/fffmle/psa_you_did_not_win_a_gift_card/ Sugar scams Sugar scammers operate all over the internet and usually come in two varieties: advance-fee scams where the scammer will ask for a payment from you before sending you lots of money, and fake check style scams where the scammer will either pull a classic fake check scam, or will do a "bill pay" style scam that involves them paying your bills, or them giving you banking information to pay your bills. If you encounter these scammers, report their accounts and move on. Google Hangouts Google Hangouts is a messaging platform used extensively by all kinds of scammers. If you are talking with someone online and they want you to switch to Hangouts, they are likely a scammer and you should proceed with caution. Publishers Clearing House scams PCH scams are often advance-fee scams, where you will be promised lots of money after you make an initial payment. You will never need to pay if you win money from the real PCH. Pet scams You are looking for a specific breed of puppy, bird, or other pet. You come across a nice-looking website that claims to be breeding them and has some available right now - they may even be on sale! The breeders are not local to your area (and may not even list a physical location) but they assure you they can safely ship the pet to you after a deposit or full payment. If you go through with the payment, you will likely be contacted by the "shipper" who will inform you about an unexpected shipping/customs/processing fee required to deliver your new pet. But there was never any pet, both the "breeder" and the "shipper" are scammers, typically operating out of Africa. These sites are rampant and account for a large percentage of online pet seller websites - they typically have a similar layout/template (screenshot - example) If you are considering buying a pet online, some easy things to check are: (1) The registration date of the domain (if it was created recently it is likely a scam website) (2) Reverse image search the pictures of available pets - you will usually find other scam websites using the same photos. (3) Copy a sentence/section of the text from the "about us" page and put it into google (in quotes) - these scammers often copy large parts of their website's text from other places. (4) Search for the domain name and look for entries on petscams.com or other scam-tracking sites. (5) Strongly consider buying/adopting your pet from a local shelter or breeder where you can see the animal in person before putting any money down. Thanks to djscsi for this entry. Fake shipping company scams These scams usually start when you try to buy something illegal online. You will be scammed for the initial payment, and then you will receive an email from the fake shipping company telling you that you need to pay them some sort of fee or bribe. If you pay this, they will keep trying to scam you with increasingly absurd stories until you stop paying, at which point they will blackmail you. If you are involved in this scam, all you can do is ignore the scammers and move on, and try to dispute your payments if possible. Chinese Upwork scam Someone will ask you to create an Upwork or other freelancer site account for them and will offer money in return. You will not be paid, and they want to use the accounts to scam people. Quickbooks invoice scam This is a fake check style scam that takes advantage of Quickbooks. The blackmail email scam The exact wording of the emails varies, but there are generally four main parts. They claim to have placed software/malware on a porn/adult video site, they claim to have a video of you masturbating or watching porn, they threaten to release the video to your friends/family/loved ones/boss/dog, and they demand that you pay them in order for them to delete the video. Rest assured that this is a very common spam campaign and there is no truth behind the email or the threats. Here are some news articles about this scam. The blackmail mail scam This is very similar to the blackmail email scam, but you will receive a letter in the mail. Rental scams Usually on local sites like Craigslist, scammers will steal photos from legitimate real estate listings and will list them for rent at or below market rate. They will generally be hesitant to tell you the address of the property for "safety reasons" and you will not be able to see the unit. They will then ask you to pay them a deposit and they claim they will ship you the keys. In reality, your money is gone and you will have no recourse. Craigslist vehicle scams A scammer will list a vehicle on Craigslist and will offer to ship you the car. In many cases they will also falsely claim to sell you the car through eBay or Amazon. If you are looking for a car on Craigslist and the seller says anything about shipping the car, having an agent, gives you a long story about why they are selling the car, or the listing price is far too low, you are talking to a scammer and you should ignore and move on. Advance-fee scam, also known as the 419 scam, or the Nigerian prince scam. You will receive a communication from someone who claims that you are entitled to a large sum of money, or you can help them obtain a large sum of money. However, they will need money from you before you receive the large sum. Man in the middle scams Man in the middle scams are very common and very hard to detect. The scammer will impersonate a company or person you are legitimately doing business with, and they will ask you to send the money to one of their own bank accounts or one controlled by a money mule. They have gained access to the legitimate persons email address, so there will be nothing suspicious about the email. To prevent this, make contact in a different way that lets you verify that the person you are talking to is the person you think you are talking to. Digit wallet scam A variation of the fake check scam, the scammer sends you money through a digital wallet (i.e. Venmo, Apple Pay, Zelle, Cash App) along with a message claiming they've sent the money to the wrong person and a request to send the money back. Customer service for these digital wallets may even suggest that you send the money back. However, the money sent is from a stolen credit card and will be removed from your account after a few days. Your transfer is not reversed since it came from your own funds. Cam girl voting/viewer scam You will encounter a "cam girl" on a dating/messaging/social media/whatever site/app, and the scammer will ask you to go to their site and sign up with your credit card. They may offer a free show, or ask you to vote for them, or any number of other fake stories. Amateur porn recruitment scam You will encounter a "pornstar" on a dating/messaging/social media/whatever site/app, and the scammer will ask you to create an adult film with hehim, but first you need to do something. The story here is usually something to do with verifying your age, or you needing to take an STD test that involves sending money to a site operated by the scammer. Hot girl SMS spam You receive a text from a random number with a message along the lines of "Hey babe I'm here in town again if you wanted to meet up this time, are you around?" accompanied by a NSFW picture of a hot girl. It's spam, and they'll direct you to their scam website that requires a credit card. Identity verification scam You will encounter someone on a dating/messaging/social media/whatever site/app, and the scammer will ask that you verify your identity as they are worried about catfishing. The scammer operates the site, and you are not talking to whoever you think you are talking to. This type of scam teases you with something, then tries to make you sign up for something else that costs money. The company involved is often innocent, but they turn a blind eye to the practice as it helps their bottom line, even if they have to occasionally issue refunds. A common variation takes place on dating sites/dating apps, where you will match with someone who claims to be a camgirl who wants you to sign up for a site and vote for her. Another variation takes place on local sites like Craigslist, where the scammers setup fake rental scams and demand that you go through a specific service for a credit check. Once you go through with it, the scammer will stop talking to you. Another variation also takes place on local sites like Craigslist, where scammers will contact you while you are selling a car and will ask you to purchase a Carfax-like report from a specific website. Multi Level Marketing or Affiliate Marketing You apply for a vague job listing for 'sales' on craigslist. Or maybe an old friend from high school adds you on Facebook and says they have an amazing business opportunity for you. Or maybe the well dressed guy who's always interviewing people in the Starbucks that you work at asks if you really want to be slinging coffee the rest of your life. The scam: MLMs are little more than pyramid schemes. They involve buying some sort of product (usually snake oil health products like body wraps or supplements) and shilling them to your friends and family. They claim that the really money is recruiting people underneath you who give you a slice of whatever they sell. And if those people underneath you recruit more people, you get a piece of their sales. Ideally if you big enough pyramid underneath you the money will roll in without any work on your part. Failure to see any profit will be your fault for not "wanting it enough." The companies will claim that you need to buy their extra training modules or webinars to really start selling. But in reality, the vast majority of people who buy into a MLM won't see a cent. At the end of the day all you'll be doing is annoying your friends and family with your constant recruitment efforts. What to look out for: Recruiters love to be vague. They won't tell you the name of the company or what exactly the job will entail. They'll pump you up with promises of "self-generating income", "being your own boss", and "owning your own company." They might ask you to read books about success and entrepreneurs. They're hoping you buy into the dream first. If you get approached via social media, check their timelines. MLMs will often instruct their victims to pretend that they've already made it. They'll constantly post about how they're hustling and making the big bucks and linking to youtube videos about success. Again, all very vague about what their job actually entails. If you think you're being recruited: Ask them what exactly the job is. If they can't answer its probably a MLM. Just walk away.
You should generally avoid answering or engaging with random phone calls. Picking up and engaging with a scam call tells the scammers that your phone number is active, and will usually lead to more calls. Tax Call You get a call from somebody claiming to be from your countries tax agency. They say you have unpaid taxes that need to be paid immediately, and you may be arrested or have other legal action taken against you if it is not paid. This scam has caused the American IRS, Canadian CRA, British HMRC, and Australian Tax Office to issue warnings. This scam happens in a wide variety of countries all over the world. Warrant Call Very similar to the tax call. You'll get a phone call from an "agent", "officer", "sheriff", or other law enforcement officer claiming that there is a warrant out for your arrest and you will be arrested very soon. They will then offer to settle everything for a fee, usually paid in giftcards. [Legal Documents/Process Server Calls] Very similar to the warrant call. You'll get a phone call from a scammer claiming that they are going to serve you legal documents, and they will threaten you with legal consequences if you refuse to comply. They may call themselves "investigators", and will sometimes give you a fake case number. Student Loan Forgiveness Scam Scammers will call you and tell you about a student loan forgiveness program, but they are interested in obtaining private information about you or demanding money in order to join the fake program. Tech Support Call You receive a call from someone with a heavy accent claiming to be a technician Microsoft or your ISP. They inform you that your PC has a virus and your online banking and other accounts may be compromised if the virus is not removed. They'll have you type in commands and view diagnostics on your PC which shows proof of the virus. Then they'll have you install remote support software so the technician can work on your PC, remove the virus, and install security software. The cost of the labor and software can be hundreds of dollars. The scam: There's no virus. The technician isn't a technician and does not work for Microsoft or your ISP. Scammers (primarily out of India) use autodialers to cold-call everyone in the US. Any file they point out to you or command they have you run is completely benign. The software they sell you is either freeware or ineffective. What to do you if you're involved with this scam: If the scammers are remotely on your computer as you read this, turn off your PC or laptop via the power button immediately, and then if possible unplug your internet connection. Some of the more vindictive tech scammers have been known to create boot passwords on your computer if they think you've become wise to them and aren't going to pay up. Hang up on the scammers, block the number, and ignore any threats about payment. Performing a system restore on your PC is usually all that is required to remove the scammer's common remote access software. Reports of identity theft from fake tech calls are uncommon, but it would still be a good idea to change your passwords for online banking and monitor your accounts for any possible fraud. How to avoid: Ignore any calls claiming that your PC has a virus. Microsoft will never contact you. If you're unsure if a call claiming to be from your ISP is legit, hang up, and then dial the customer support number listed on a recent bill. If you have elderly relatives or family that isn't tech savvy, take the time to fill them in on this scam. Chinese government scam This scam is aimed at Chinese people living in Europe and North America, and involves a voicemail from someone claiming to be associated with the Chinese government, usually through the Chinese consulate/embassy, who is threatening legal action or making general threats. Chinese shipping scam This scam is similar to the Chinese government scam, but involves a seized/suspicious package, and the scammers will connect the victim to other scammers posing as Chinese government investigators. Social security suspension scam You will receive a call from someone claiming to work for the government regarding suspicious activity, fraud, or serious crimes connected to your social security number. You'll be asked to speak to an operator and the operator will explain the steps you need to follow in order to fix the problems. It's all a scam, and will lead to you losing money and could lead to identity theft if you give them private financial information. Utilities cutoff You get a call from someone who claims that they are from your utility company, and they claim that your utilities will be shut off unless you immediately pay. The scammer will usually ask for payment via gift cards, although they may ask for payment in other ways, such as Western Union or bitcoin. Relative in custody Scammer claims to be the police, and they have your son/daughtenephew/estranged twin in custody. You need to post bail (for some reason in iTunes gift cards or MoneyGram) immediately or the consequences will never be the same. Mexican family scam This scam comes in many different flavours, but always involves someone in your family and Mexico. Sometimes the scammer will claim that your family member has been detained, sometimes the scammer will claim that your family member has been kidnapped, and sometimes the scammer will claim that your family member is injured and needs help. General family scams Scammers will gather a large amount of information about you and target your family members using different stories with the goal of gettimg them to send money. One ring scam Scammers will call you from an international number with the goal of getting you to return their call, causing you to incur expensive calling fees.
Online shopping scams
THE GOLDEN RULE OF ONLINE SHOPPING: If it sounds too good to be true, it probably is. Dropshipping An ad on reddit or social media sites like Facebook and Instagram offers items at huge discounts or even free (sometimes requiring you to reblog or like their page). They just ask you to pay shipping. The scam: The item will turn out to be very low quality and will take weeks or even months to arrive. Sometimes the item never arrives, and the store disappears or stops responding. The seller drop-ships the item from China. The item may only cost a few dollars, and the Chinese government actually pays for the shipping. You end up paying $10-$15 dollars for a $4 item, with the scammer keeping the profit. If you find one of these scams but really have your heart set on the item, you can find it on AliExpress or another Chinese retailer. Influencer scams A user will reach out to you on a social media platform, usually Instagram, and offer you the chance to partner with them and receive a free/discounted product, as long as you pay shipping. This is a different version of the dropshipping scam, and is just a marketing technique to get you to buy their products. Triangulation fraud Triangulation fraud occurs when you make a purchase on a site like Amazon or eBay for an item at a lower than market price, and receive an item that was clearly purchased new at full price. The scammer uses a stolen credit card to order your item, while the money from the listing is almost all profit for the scammer. Instagram influencer scams Someone will message you on Instagram asking you to promote their products, and offering you a discount code. The items are Chinese junk, and the offer is made to many people at a time. Cheap Items Many websites pop up and offer expensive products, including electronics, clothes, watches, sunglasses, and shoes at very low prices. The scam: Some sites are selling cheap knock-offs. Some will just take your money and run. What to do if you think you're involved with this scam: Contact your bank or credit card and dispute the charge. How to avoid: The sites often have every brand-name shoe or fashion item (Air Jordan, Yeezy, Gucci, etc) in stock and often at a discounted price. The site will claim to be an outlet for a major brand or even a specific line or item. The site will have images at the bottom claiming to be Secured by Norton or various official payment processors but not actual links. The site will have poor grammar and a mish-mash of categories. Recently, established websites will get hacked or their domain name jacked and turned into scam stores, meaning the domain name of the store will be completely unrelated to the items they're selling. If the deal sounds too good to be true it probably is. Nobody is offering brand new iPhones or Beats or Nintendo Switches for 75% off. Cheap Amazon 3rd Party Items You're on Amazon or maybe just Googling for an item and you see it for an unbelievable price from a third-party seller. You know Amazon has your back so you order it. The scam: One of three things usually happen: 1) The seller marks the items as shipped and sends a fake tracking number. Amazon releases the funds to the seller, and the seller disappears. Amazon ultimately refunds your money. 2) The seller immediately cancels the order and instructs you to re-order the item directly from their website, usually with the guarantee that the order is still protected by Amazon. The seller takes your money and runs. Amazon informs you that they do not offer protection on items sold outside of Amazon and cannot help you. 2) The seller immediately cancels the order and instructs you to instead send payment via an unused Amazon gift card by sending the code on the back via email. Once the seller uses the code, the money on the card is gone and cannot be refunded. How to avoid: These scammers can be identified by looking at their Amazon storefronts. They'll be brand new sellers offering a wide range of items at unbelievable prices. Usually their Amazon names will be gibberish, or a variation on FIRSTNAME.LASTNAME. Occasionally however, established storefronts will be hacked. If the deal is too good to be true its most likely a scam. Scams on eBay There are scams on eBay targeting both buyers and sellers. As a seller, you should look out for people who privately message you regarding the order, especially if they ask you to ship to a different address or ask to negotiate via text/email/a messaging service. As a buyer you should look out for new accounts selling in-demand items, established accounts selling in-demand items that they have no previous connection to (you can check their feedback history for a general idea of what they bought/sold in the past), and lookout for people who ask you to go off eBay and use another service to complete the transaction. In many cases you will receive a fake tracking number and your money will be help up for up to a month. Scams on Amazon There are scams on Amazon targeting both buyers and sellers. As a seller, you should look out for people who message you about a listing. As a buyer you should look out for listings that have an email address for you to contact the person to complete the transaction, and you should look out for cheap listings of in-demand items. Scams on Reddit Reddit accounts are frequently purchased and sold by fraudsters who wish to use the high karma count + the age of the account to scam people on buy/sell subreddits. You need to take precautions and be safe whenever you are making a transaction online. Computer scams Virus scam A popup or other ad will say that you have a virus and you need to follow their advice in order to remove it. They are lying, and either want you to install malware or pay for their software.
Chinese Brushing / direct shipping If you have ever received an unsolicited small package from China, your address was used to brush. Vendors place fake orders for their own products and send out the orders so that they can increase their ratings. Money flipping Scammer claims to be a banking insider who can double/triple/bazoople any amount of money you send them, with no consequences of any kind. Obviously, the money disappears into their wallet the moment you send it.
Dragonchain Great Reddit Scaling Bake-Off Public Proposal
Dragonchain Public Proposal TL;DR:
Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and postsper Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625. Watch Joe walk through the entire proposal and answer questions onYouTube. This proposal is also available on the Dragonchain blog.
Hello Reddit and Ethereum community!
I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale. For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube. We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.
Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.
Response and PoC
In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.
A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks. 24 hours in 4 minutes (YouTube): 24 hours in 4 minutes The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period. Tooling to reproduce our demo is available here: https://github.com/dragonchain/spirit-bomb
Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.
Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired. Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.
An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity. TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block. TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.
Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain. With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times. We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment. Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.
Flexibility in Scaling
Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems. We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
LBRY - To allow users to deploy content natively to LBRY
MakerDAO to allow users to lend small amounts backed by their Reddit community points.
STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.
Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction. Dragonchain Fees Table
How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node. Getting started is easy...
Download Dragonchain’s dctl
Input three commands into a terminal
Build an image
More information can be found in our Get started documents.
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain. Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain. After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks. Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.
Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.
Costs and resources
Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD. For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments. Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.
This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users. Over a 5 day period, your scaling PoC should be able to handle: *100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes. Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum. Reddit Scaling on Ethereum
Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
Operational on-premises capabilities
Operational deployment to any datacenter
Over 700 independent Community Verification Nodes with proof of ownership
Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)
Usability Scaling solutions should have a simple end user experience.
Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node. Examples:
Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.
Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users. All of Reddit's Transactions on Blockchain (month) Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees. Reddit Internal Token Transaction Fees Reddit Ethereum Token Transaction Fees When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
In a combination of the above, customers could cover aggregated fees.
Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.
Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here. Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here. In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here. A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.
Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.
Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.
Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible APIs should be well documented and stable
Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected. Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.
Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!
Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.
Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR. Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.
Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.
Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.
Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw
Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.
A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.
Bonus points Public, third-party implementation review available or in progress
Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.
Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.
One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).
Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).
Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!
Disney Releases Blockchain Platform as Open Source
The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group. https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html
In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney. Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
Obtain VP support and approval for the release
Verify ownership of the software to be released
Verify that no proprietary content would be released
Convince the organization that there was a value to the open source community
Convince the organization that there was a value to Disney
Offer the plan for ongoing maintenance of the project outside of Disney
Itemize competing projects

Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney. The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release. Original OSSRELASE-10 document
The Dow rose 131.06, or 0.48%, to 27,665.64, the Nasdaq lost 66.05, or 0.60%, to 10,853.55, and the S&P 500 advanced 1.78, or 0.05%, to 3,340.97. Traders at /thewallstreet cheered as volatility returned to the stock market. The major averages finished Friday's trading in mixed fashion, as dip buyers provided support for the Dow and the continued tech selloff made the Nasdaq the laggard once again. The chances for another round of fiscal stimulus ahead of the election were hurt yesterday after Democrats stopped the passage of the "skinny" GOP package, but the U.S. economy looks poised for a strong rebound in Q3, corporate earnings continue to largely overshoot pessimistic forecasts and the Fed remains "all in," leaving investors to mull the cross-currents. Similar to the days before, today's price action was technically-oriented given the absence of market-moving news and the losses in stocks like AAPL, -1.3%, AMZN, -1.9%, and MSFT, -0.7% on no specific corporate news. Apple shares fell 7.4% this week. The difference today was that their losses were offset by relative strength in the cyclical sectors, namely industrials (+1.4%), materials (+1.3%), and financials (+0.8%). Still, when Apple and Amazon are down more than 1.0%, there must be more winners than losers to make a meaningful difference. There were more of the latter on Friday, as declining issues outpaced advancing issues at the NYSE and Nasdaq. The information technology (-0.8%), consumer discretionary (-0.3%), and communication services (-0.3%) sectors ended the day in negative territory due to their exposure to the mega-cap stocks. Interestingly, the S&P 500 was down as much as 0.9% intraday and fell below its 50-day moving average (3322). A broad rebound in the afternoon, however, helped the benchmark index turn positive and close above the key technical level. In TikTok news, President Trump said that the deadline established for China's ByteDance to sell video-sharing service TikTok's U.S. operations would not be extended, Reuters reported. "It'll either be closed up or they'll sell it," the president told reporters, adding, "There will be no extension of the TikTok deadline." MSFT in partnership with WMT and Oracle have been seen as the leading suitors to purchase TikTok's operations in the U.S., Canada, Australia and New Zealand. Subsequently, Reuters reported that Chinese officials are so opposed to a forced sale of TikTok's U.S. operations that they would prefer to see the app shut down in the U.S. over that conclusion. Reuters noted that China was willing, if needed, to use revisions it made to a technology exports list on Aug. 28 to delay any deal reached by ByteDance. Electric vehicle hopeful NKLA continued its fight this morning with a short-seller, which now appears to be "short-sellers." Nikola issued a statement in response to claims made about the company by activist short-seller Hindenburg Research yesterday, calling the firm's report "a hit job for short sale profit driven by greed." Nikola, which added that it has "nothing to hide and we will refute these allegations," announced that it has retained law firm Kirkland & Ellis to evaluate potential legal recourse and intends to bring the actions of the short-seller, together with evidence and documentation, to the attention of the SEC. Following the company's press release regarding the response, Andrew Left's Citron Research said via Twitter, "Congrats to Hindenburg for exposing what appears to be a total fraud with $NKLA. Citron will cover half of all legal expenses. You can't SLAPP the truth away. Explains why Milton sold at $10 this June $NKLA response warrants an SEC investigation to maintain integrity of EV mkt." After having dropped 11% on Thursday, Nikola shares fell a further 14.5%. Meanwhile, CNBC reported that AAPL has updated its App Store guidelines ahead of the release of iOS 14, with one major revision relating to game streaming services. The tech giant said in its revised guidelines that services such as Google Stadia (GOOG) and Microsoft xCloud are explicitly permitted, though under the condition that games offered in the service must be downloaded directly from the App Store, not from an all-in-one app. Among the noteworthy gainers was Shares of ORCL, which was in focus after the company reported what Barclays analyst Raimo Lenschow called a "surprisingly strong beat" and growth on licenses despite the continued macro uncertainty. NOG, which rose 1.3% after acquiring interests in the Delaware Basin and raising Q3 production guidance. Also higher was CX, which gained 8.3% in New York after Morgan Stanley analyst Nikolaj Lippmann upgraded the stock to Overweight from Equal Weight. Among the notable losers was AMRS, which dropped 25.8% after responding to a lawsuit filed by Lavvan against the company for patent infringement and trade secret misappropriation. Also lower was CHWY, which declined 9.8% after reporting some cats have tried to take over the company with whiteclaws. Despite a blowout fiscal Q4 report, PTON were 4.2% lower following last night's from the fitness products and services provider. Elsewhere stocks were higher, with the Shanghai composite up 0.79% to around 3,260.35 while the Shenzhen component rose 1.57% to about 12,942.95. Hong Kong’s Hang Seng index advanced 0.78% to end its trading day at 24,503.31.
The U.S. Dollar Index (93.35, +0.01, unch) reclaimed its overnight loss, gaining 0.7% for the week.

U.S. Treasuries ended the abbreviated week with modest gains across the curve. The cash session started with some light selling for the second day in a row, but the market recovered from the early dip with ease.
2-yr: -1 bp to 0.13% (-3 bps for the week)
3-yr: -1 bp to 0.15% (-3 bps for the week)

Gold slipped on Friday on a lack of further stimulus from the European Central Bank and the U.S. government, but for the week the safe-haven metal was set to end higher. Crude remained on track for a second weekly drop as investors expected a global glut to persist if demand weakens further with rising COVID-19 cases in some countries.
WTI crude: +0.2% to $37.34/bbl
Gold: -0.8% to $1948.30/ozt
Copper: +1.3% to $3.04/lb
Bitcoin is struggling to gather upside traction despite repeated defense of support at $10,000. The top cryptocurrency’s sell-off from the August high of $12,476 looks to have come to a halt near $10,000 over the past seven days.
Bitcoin: $10,332.31 (24hr: +0.45%)
Ethereum: $369.66 (24hr: +1.48%)
Ripple: $0.24 (24hr: -0.10%)

Russy -10.3% YTD
Total CPI increased 0.4% m/m while core CPI, which excludes food and energy, also rose 0.4%. Those gains left total CPI up 1.3% yyr and core CPI up 1.7% yyr. The key takeaway from the report, which featured the largest increase in the index for used cars and trucks (+5.4%) since March 1969, is that the increase in the all items index was broad-based; nonetheless, annual inflation rates are still running well below 2.0%, so there is still more noise than bothersome policy signal in the August report.

Wall Street Breakfast: Volatile Week Ends In Quad Witching Session
U.S. equity futures held up overnight following another selloff on Wall Street that was led by major tech names. Contracts tied to the Dow and S&P 500 are hugging the flatline, while Nasdaq futures pared recent losses by climbing 0.6%. Mixed messaging around a potential coronavirus vaccine, as well as the passage of further fiscal stimulus, weighed on the market, while investors are gearing up for consumer sentiment data set for release at 10 a.m. ET. Don't forget that it's also quad witching day, which refers to the simultaneous expiration of market index futures, stock futures, market index options and stock options. "These days tend to get a lot of press for all of the volume they create, but historically they are nearly always a non-event," said Ryan Detrick, senior market strategist at LPL Financial. Spending deal to avoid government shutdown While there may be disagreement over another round of coronavirus relief, lawmakers are aiming to unveil a bipartisan spending bill today to avert a government shutdown on Oct. 1. The "clean" legislation, largely devoid of any controversial measures, should keep the government funded into mid-December. "I don't think anybody wants to be responsible for shutting down the government on the eve of an election in the middle of a pandemic, so it's a rare outbreak of common sense on both sides," said Rep. Tom Cole (R., Okla.), a senior member of the House Appropriations Committee. New round of farm aid "Starting next week my administration is committing an additional $13B in relief to help farmers recover from the China virus," President Trump announced a campaign rally in Mosinee, Wisconsin. The new aid is the second tranche of money issued as part of the Trump administration's Coronavirus Food Assistance Program. In April, the administration unveiled $19B in relief for the agriculture sector under the CARES Act, including $16B in direct payments to farmers and ranchers and $3B in mass purchases of dairy, meat and produce. Fed mulls extension of bank dividend curbs Due to heightened economic uncertainty, the Federal Reserve is considering extending its caps on banks' dividends and stock repurchases for the rest of the year. The U.S. central bank made the announcement along with its release of hypothetical scenarios for the second round of stress tests that it's requiring due to the COVID-19 pandemic. Unlike an earlier round of stress tests this year, the Fed will release the results of the tests for each of the 33 lenders, rather than providing aggregate results for the group. Sub-zero rates The Bank of England held its benchmark policy rate at 0.1% on Thursday, but indicated it could cut interest rates below zero for the first time in its 326-year history. While recent domestic economic data has been a bit stronger than expected, it's "unclear how the economy will perform further out," according to the Monetary Policy Committee. Another major risk facing the U.K. economy relates to the post-Brexit trade discussions between the U.K. and the EU, which have recently soured. Terms of a TikTok deal The Trump administration spent Thursday reviewing proposals on the TikTok-Oracle (NYSE:ORCL) partnership, which currently has many moving parts. TikTok owner ByteDance (BDNCE) agreed to list the video-sharing app on a U.S. stock exchange, which could happen within a year, though there are still concerns over whether the Chinese parent would be allowed to retain a majority stake in the new company. Meanwhile, shares in China's Tencent (OTCPK:TCEHY) tumbled into the U.S. closing bell following reports that its investments are drawing new national security attention. Exchange dealmaking Seeing off competing bids from Deutsche Borse (OTCPK:DBORY) and Switzerland's SIX, the London Stock Exchange (OTCPK:LNSTY) is in exclusive talks to sell Borsa Italiana to France's Euronext (OTCPK:EUXTF). Offloading the Milan stock exchange would help LSE achieve regulatory remedies for its $27B purchase of data provider Refinitiv, which is owned by Blackstone (NYSE:BX) and Thomson Reuters (NYSE:TRI). The deal is politically sensitive in Rome because of concerns about who could take control of Borsa Italiana's bond platform, which handles trading of Italy's government debt. New COVID-19 restrictions across Europe Targeted lockdowns and local restrictions are returning to Europe as the region tries to avoid broad economic damage amid a surge in coronavirus cases. "Weekly cases have now exceeded those reported when the pandemic first peaked in Europe in March," the WHO's regional director for Europe Hans Kluge told an online news conference. "Although these numbers reflect more comprehensive testing, it also shows alarming rates of transmission across the region." Pubs and restaurants must shut early and household mixing has been limited in northeast England, while social gatherings of more than six people have been banned across the country. French authorities are meanwhile preparing tighter restrictions in several cities, while Spain's Madrid has moved to "reduce mobility and contacts" in areas with high infection rates. Go Deeper: Israel becomes first developed country to enforce a second nationwide shutdown. Pandemic closures see restaurants hit the hardest About 60% of businesses that have closed their doors during the coronavirus pandemic will never reopen, and restaurants have suffered the most, according to new data from Yelp. The National Restaurant Association also said this week that 100,000 restaurants have closed either permanently or long term, adding that the sector is on track to lose $240B in sales this year. A number of factors have made it especially difficult for eateries, which tend to operate on thin margins even in the best of times. What else is happening... Unity (NYSE:U) to raise $1.3B in IPO, prices 25M shares above range. New York files civil charges against J&J (NYSE:JNJ) over opioids. Walmart (NYSE:WMT) hikes pay for about 165,000 hourly employees. Dave & Buster's (NASDAQ:PLAY) stumbles on bankruptcy speculation. Proposed Boeing (NYSE:BA) 737 MAX safety upgrades endorsed by NTSB. Nat gas tumbles by most in two years after stockpile gain.

COVID-19's Economic Impact in Canada: a collection of stats on jobs losses, investment returns, consumer confidence, interest rates, housing, and future forecasts
Over the past few weeks, the COVID crisis has hurt the Canadian economy and the average Canadian's financial situation in more ways than one. I tried to tally up the damage by going through the info that's been published thus far (by Stats Can, the Bank of Canada, the Parliamentary Budget Officer, news sites, etc.), and have put together some visualizations and commentary on the data. In summary:
Stats Can's March labour force survey showed that 3.1 million Canadians had their job situation impacted negatively during the survey period (March 15 - March 21); that's ~16% of Canada's total labour force
1 million Canadians lost their jobs; 0.8 million had a job but didn't work any hours; 1.3 million had a job but worked less than half of their usual hours
Canadians worked 15% fewer hours in the month of March vs February; the impact was highest in Quebec (-19%), and lowest in Newfoundland and Labrador (-8.4%)
As of April 13th, nearly 6 million Canadians have applied for CERB or EI (reported by the CBC)
Investments (2020 year-to-date returns)
Stock markets are down by roughly 15 - 20% (TSX Composite is down by 17%)
Bond markets are roughly flat
Gold is up by 14% (as investors tend to flock to gold in times of economic uncertainty)
Bitcoin is down by 4%
Canadian oil prices are down by ~70%
Google search volume in Canada for the terms "recession" and "layoff" are the highest on record, even surpassing the search volume during the 2008 recession
The Conference Board of Canada's "Index of Consumer Confidence" registered the largest monthly decline ever in March
The Bank of Canada cut the overnight rate 3 separate times in March, dropping the rate from 1.75% to 0.25%
The rate hasn't been this low since the 2008 recession
The Toronto Regional Real Estate Board showed a 16% decline in home sale volumes in the Greater Toronto Area in the second half of March
RBC Economics expects that “Canada’s housing market will slow to a crawl this spring”, and that housing prices will face a temporary set-back — with an estimated 2.9% year-over-year price decline in the second half of 2020
Post-COVID Economic Forecasts
On April 9th, Canada’s Parliamentary Budget Officer released a “scenario analysis” report on the potential impact of COVID-19 on the Canadian economy.
It’s estimated that the federal government’s responses to the COVID crisis will have a total cost of over $105 billion
As a result, Canada’s budget deficit in the 2020-21 fiscal year will rise to $185 billion, or roughly 8.5% of GDP
Canada’s budget deficit hasn’t been this high (based on % of GDP) since the 1984-85 fiscal year
In 2020, Canada will have real GDP growth of -5.1%, and an unemployment rate of 12.4%; for context, Canada's real GDP only declined by 3.3% in 2009
The number of unemployed Canadians will rise from 1.2 million (Q4 2019) to 3.1 million (Q3 2020)
These points are addressed in chart form at the link above. You can download a spreadsheet which contains all of the source data / charts. There's also a summary of the emergency response initiatives announced by the federal government (CERB, GST credit, CCB one-time payment, the 75% wage subsidy, etc.), and thoughts about steps that Canadians can take today to improve their financial situation. I'll continue to update the page as new economic stats roll-in, and as the government announces new initiatives. I'd love to hear your thoughts about COVID's economic impact in Canada. Also, please feel free to share any other stats, articles, or reports that you think are relevant!

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake
https://preview.redd.it/b80c05tnb9e51.jpg?width=2550&format=pjpg&auto=webp&s=850282c1a3962466ed44f73886dae1c8872d0f31 Submitted for consideration toThe Great Reddit Scaling Bake-Off Baked by the pastry chefs atOffchain Labs Please send questions or comments to [[email protected] ](mailto:[email protected]) 1. Overview We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too! Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know). To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts. 1.1 Why Ethereum Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract. The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both. Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice. 1.2 Why Arbitrum While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools. Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users. We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth. 2. Arbitrum at a glance Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes. Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability. Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow. Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below. Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn. Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask. Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract. Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details). Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users. Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum. Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain. Limitations Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals. As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit). Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here). So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality. 3. The recipe: How Arbitrum Rollup works For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents: Arbitrum Rollup Whitepaper Arbitrum academic paper (describes a previous version of Arbitrum) 4. Developer docs and APIs For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/. Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release. 5. Who are the validators? As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators? Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers. Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators. 6. Reddit Contract Support Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain. Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain. For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2. Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios. In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process. To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum. When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) . The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform. 8. Benchmarks and costs In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking. Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here. Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum. On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support: Over a 5 day period, your scaling PoC should be able to handle:
100,000 point claims (minting & distributing points)
75,000 one-off points burning
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.) We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks). Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c. We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic. Our model. Our cost model includes several sources of cost:
L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system. Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.) 9. Status of Arbitrum Rollup Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade. Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet. 10. Reddit Universe Arbitrum Rollup Chain The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo. If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access. 11. Even more scaling: Arbitrum Sidechains Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide. While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic. The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout. Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator. Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol. Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest. We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help. While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined). 12. How Arbitrum compares We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects. Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components. But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.
