Interesting CSW posts from 2010

This should be an interesting read for anyone attempting to decide the merits of Craig Wright's claims, as it does relate to his character. The linked posts from 2010 relate to security models, not Bitcoin. This was more than a year before Wright ever mentioned Bitcoin.

How is your passive income from Crypto going in 2020? So far I have made around $11k plus from approximately 13 or so sources. Details below.

I remember in 2017 there were epic stories of people making fortunes from free crypto-giveaways – for example, the nano faucet gave people fantastic wealth if they held on all year. Then there were things like the various bitcoin forks – great if you cashed in.
Now in 2020 there seems to be another uptrend in terms of the ability to get “free crypto” – in various ways. Overtime this can build up to quite a lot.
This year I have:
  1. Coinbase earn – I’ve done almost all of these and have had a few referrals. I think I earned maybe $200 or so all up, cashed in BTC, and that BTC is probably around $400
  2. Reddit moons – I have earned 3100 moons, sold for roughly $220
  3. Uniswap – My free 400 tokens are still held, so they are worth maybe $1200
  4. Binance Coin – lots of staking and lottery compensation payments here – for example, I recently sold my Flamingo, Venus and Alpha tokens – maybe $30;
  5. Hex – Yes I know it’s a scam, but I think I bit have a decent little payout in a month when my 90% locked tokens open (won’t say how much as that will reveal my BTC wallet holdings);
  6. Swissborg – A fun little “guess the bitcoin app” that has $50 worth of tokens in it now;
  7. Brave Browser – I’ve earned like $20 from that this year (insert: “Its not much but its honest work gif”);
  8. Uniswap Pools etc – Hard to calculate this one but I’m earning some really great fees and Uni from pooling WBTC and WETH – about 0.5% return a week. Was also previously staking Uni / ETH - I made $1000 in fees but mostly gobbled up by impermanent loss.
  9. Honeyswap – Every 48 hours, I log-in to get free honey from the faucet – around $40 or so;
  10. Survey – I did a phone survey for a local project and got given $100 of free tokens;
  11. Livepeer – No idea what this is but I sold two airdrops for around $20;
  12. Nexus Mutual – Probably the king here. Invested $1200 worth. Received a 58% dividend on the first day of staking (say $700) which I reinvested. That $700 is now $8000 or something ridiculous (and itself earning rewards), plus another 13 NXM (So another $416 on top).
  13. And then lots of rats and mice rewards from things like staking Celsius, staking Tezos referral rewards etc. I even have 3000 of that damn Pi coin thing but don’t know where that is going.
  14. And to top it off a free ledger nano for participation in a private group on FB
  15. (EDIT: I forgot to mention I am currently winning a "pick four" crypto competition that I entered in January where you pick four cryptos and the winner takes the pot. I picked BTC, FTX, SNX and CEL - so that might be another $200 to add to my collection!)
So in all, that is an entire bitcoin just for doing a bunch of crazy stuff. Who said it was difficult to join the 21 million club?
So for some people that might be considered a decent pay package for a full time job! What other opportunities do you guys have where you have passive income coming from crypto? Am I missing any obvious ones here?

Name a 2017 / 2018 moonshot IEO that was initially popular and is now either dead or ghosting away - I'll start, SVD

SVD is Savedroid. Savedroid was an ICO in 2018 right at the peak of the mania, not quite at the top price wise, but still when greed was insanely high.
Now SVD raised an incredible $50 million, for an app that simply automates your saving. That's it. In today's environment I can see that going for maybe $500k or so, IF that. Maybe they could call themselves a Defi food coin instead and get some money in via uniswap.
Demand was very high, with all tokens sold in a week. So all it would do is you would set some criteria - say, if I do 10 push ups a day I want to save $1 into BTC, you'll input that and the app would buy the bitcoin with $1. (I have no idea why you couldn't do that manually, but anyway).
Things got off to a bad start when on day 1 the CEO, Yassin Hankir decided to pull a "fake exit scam", with a twitter message "thanks guys, over and out" with the website replaced with the message "...and its gone". He then back pedalled and said actually it was a joke and meant to show case other scammy projects. Investors weren't particularly amused, especially as this coincided with the coin listing, causing the price to plunge into the eternal depths of hell faster than Grin Coin or an FTX listing.
Well that doesn't really matter because the project seems to have died, with the founder moving onto another project, leaving behind an app that is apparently barely functional, and doesn't even allow ICO investors to use their SVD on the platform.
The ICO price was 1 cent - pretty cheap right? Well no, apparently the token price is now $0.0000541 with a daily volume of zero. Market cap it $158k, but no idea how that is calculated. Not exactly a great way to save if you were an investor!
Naturally they have been delisted from all but a couple of obscure DEXes and even there volume is dead (this is despite various promises of top exchanges).
And the cherry on top - last week the project rebranded as "Trumpbit", a new app that does the same thing (converts your money into BTC) by a certain amount each time Trump tweets. Only problem is people are having trouble moving their funds across from one platform to another, lost email addresses etc. I have no idea what happens if Trump loses the election, maybe it will be come Bidenbit or something. This is of course leaving aside the fact that your $50M ICO has rebranded to a coin named after Trump (not a political comment but a bit of a head scratcher).
You can even pop by their reddit sub, where there have been around 4 comments in 1 year, or if you are bold, visit their telegram group to see various howls of outrage and people wondering where their investment has gone.
Name and shame your preferred coin of death!

Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Where can I spend bitcoins?

Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.

Coinmap and AirBitz are helpful to find local businesses accepting bitcoins. A good resource for UK residents is at wheretospendbitcoins.co.uk.
There are also lots of charities which accept bitcoin donations.

Merchant Resources

There are several benefits to accepting bitcoin as a payment option if you are a merchant;
If you are interested in accepting bitcoin as a payment method, there are several options available;

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

Bitcoin Fullnode Install Guide for Dummies ;-)

Bitcoin Fullnode Install Guide for Dummies ;-)
Feel free to stop at Level 0 or Level 1, which is fine. More advanced configs are offered to those with more tech savvy. This guide, obviously assumes a Windows 10 install, but other OSes work fine, just find a different guide. BTW, the "For Dummies" is a callback to a set of "tech" books in the 90's intended to be as easy as possible. It is in jest and not intended to insult the reader. Finally, if you dislike the formatting, a well formatted copy can be found here
There is a fairly small subset of Bitcoin users that run a full node. I think the idea of running a full node has gotten a bad rap over the years since there is so much talk about running on a Raspberry Pi, or getting zippy SSDs. Although all of this can be fun, it is often not really required at all. Here are some ways to run a full node starting with the very simple. I'll get into more complex configs, but these are all optional.

Tech Skill Level: 0 (the basics)

  1. Download Bitcoin Core
  2. Launch the downloaded installer and install the app
  3. Launch the installed "Bitcoin Core" app and let it run overnight
In many cases, thats it. If your running a new machine with a fairly good internet connection, 8 or 9 hours will be enough to complete the "Initial Block Download" (IBD). This may fill up your drive a bit, but again, on most new machines, 300 GB of space isn't that hard to come by.

Tech Skill Level: 1 (encrypted wallet)

One thing we left out in the level-0 exercise is encrypting your wallet. It's easy enough to do well, but a bit more difficult to do right. The main challenge is that humans generate really poor passwords. If you want a good password, the best way is to use something called "diceware". Basically, you just grab 4 or 5 dice and each throw of the dice represents a certain word on a special list. The throw {1,4,5,3,1} for example would be the word camping on the EFF-diceware-wordlist. So you repeat this a few times until you have a list of 8 or so words which becomes the passphrase you use to encrypt your wallet. Write it down, it is always hard to remember at first. So at level-1 your list becomes:
  1. Download Bitcoin Core
  2. Launch the downloaded installer and install the app
  3. Launch the installed "Bitcoin Core" app and let it run overnight
  4. Choose Encrypt Wallet from the Settings menu
  5. Enter your 8 word (or so) passphrase generated using the Diceware method

Wallet Encryption Dialog

Tech Skill Level: 2 (enable pruning if needed)

Though I said "300 GB of space isn't hard to come by", some times it actually is. If space is an issue, a simple way to fix it is to tell bitcoin to simple take less space. This is called "pruning" and can take that number from 300 GB down to below 5 GB. If you can't find 5 GB, then you'll have to read ahead to level-4 to add USB storage. But the good news is, enabling pruning is pretty easy, we just add another step to our working list:
  1. Download Bitcoin Core
  2. Launch the downloaded installer and install the app
  3. Launch the installed "Bitcoin Core" app and let it run overnight
  4. Do the wallet encryption steps here if you wish
  5. Choose Options from the Settings menu
  6. Choose Prune block storage to: and select the max size for the blocks to use
  7. Exit and restart the bitcoin application for the changes to take effect

Pruning Dialog
Note, even setting this to 1 GB will still leave you with about a 4.5 GB install. The blocks take up a lot of space, but the chainstate and other folders eat up at least 3.5 GB and they can't be pruned. Also, be aware, to disable pruning requires you to perform the entire IBD again. While pruned some other functions my be disabled as well, so just know that pruning does limit some functionality.

Tech Skill Level: 3 (verify the installer)

Although this is arguably something that should be done at level-0, some find the intricacies of comparing hash (thumbprint) values to be tedious and beyond the scope of a beginner. You will find these types of hash compares suggested quite often as a way to prevent running tainted programs. Programs are often tainted by bad disk or network performance, but most often, taint is malicious code inserted by viruses or malware. This is a way to guard yourself against those types of attacks.
What I cover here is a very basic comparison on the certificate, but a more thorough verification advised by mosts uses a program called Gpg4Win, and is beyond the scope of this beginners guide. But regardless, most users should strive to do this minimum level of validation.
  1. Download Bitcoin Core
  2. Launch the downloaded installer
  3. When prompted "Do you want to allow..." click Show more details
  4. In the details section select Show information about the publisher's certificate
  5. In the certificate window select the Details tab
  6. In the Details tab Subject should start with "CN = Bitcoin Core Code Signing Association"
  7. Ensure Thumbprint in Details reads ea27d3cefb3eb715ed214176a5d027e01ba1ee86
  8. If the checks pass, click OK to exit the certificate window and Yes to allow the installer to run.
  9. Launch the installed "Bitcoin Core" app and let it run overnight
  10. Do the wallet encryption steps here if you wish
  11. Do the optional pruning steps here if you wish

Certification Validation Windows
Note: The certificate used to sign the current Bitcoin installer is only valid from March 2020 to March 2021. After that point the thumbprint on the certificate will change. This is by design and intentional. If your reading this post after March 2021, then it is understood that the thumbprint has changed.

Tech Skill Level: 4 (use secondary storage)

We glossed over the "new machine with fairly good internet" part. Truth be known many people do not have fairly new machines, and find the IBD to take longer than the "over night" best wishes. For most people the slowdown is the disk access when calculating what is called chainstate. This requires fast random reads and writes to the disk. If you have an SSD disk, this will be no problem, but if you have a non-SSD "spinning" disk, random writes are always slow. Though an SSD will speed things up, they are pricey, so a nice middle ground may be a simple high-end USB key drive. You can get some with 10 to 15 MB/s random writes for $20 on Amazon. This is usually a order of magnitude faster than a "spinning" disk. And with pruning (see level-2), a small USB drive should be fine.
Once you decide on a drive, the tricky part will be to enable external storage. It requires editing a configuration file and adding a line. First, we want to create a directory on the key drive. You will need to determine the drive letter of your USB key drive. For the sake of this example, we will assume it is D:, but you must determine this yourself and correct the example. Once you know the drive letter, create a blank folder on the drive called Bitcoin. So for this example, creating Bitcoin on drive D: will create the path D:\Bitcoin. Once done, assuming that D: is your drive, here are the new steps including the edit of the configuration file:
  1. Download Bitcoin Core
  2. Launch the installer, verify it, then run it
  3. Launch the installed "Bitcoin Core" app and let it run overnight
  4. Do the wallet encryption steps here if you wish
  5. Do the optional pruning steps here if you wish
  6. Launch "Notepad" by typing "Notepad.exe" in the windows search bar then click Open
  7. Type the line datadir=D:\Bitcoin (depending on your drive letter) in the blank file
  8. Choose Save from the File menu in notepad
  9. Type %APPDATA%\Bitcoin\bitcoin.conf (note the percent signs) in the File name box
  10. Select All Files from the Save as type dropdown
  11. Click the Save button and overwrite the file if prompted
  12. Exit and restart the bitcoin application for the changes to take effect

Save As Dialog
Now that you've reached this level of technical expertise, there are many new configuration options that you can begin to modify if you wish. Most configuration data is contained in the bitcoin.conf file and learning how to maintain it is a key step for a node operator.

Tech Skill Level: 5 (all other customizations)

Here's a short list of various things you can ADD to your bitcoin.conf file. You generally just add a new line for each configuration settings.
  • addresstype=bech32
  • changetype=bech32
The addresstype / changetype allows your wallet to use the native-segwit (bech32) format. This is the most efficient and inexpensive way to spend bitcoin, and is a recommended configuration. The default uses something called p2sh-segwit which is more compatible with older wallets, but more expensive to spend.
  • minrelaytxfee=0.00000011
Changing the minrelaytxfee setting allows you to help propagate lower fee transactions. It will require more memory but TXN memory is capped at 300 MB by default anyways, so if you have enough memory, it is a good setting to choose.
  • dbcache=2048
The dbcache setting controls how many MB of memory the program will use for the chainstate database. Since this is a key bottleneck in the IBD, setting this value high (2048 MB) will greatly speed up the IBD, assuming you have the memory to spare
  • blocksdir=C:\Bitcoin
  • datadir=D:\Bitcoin
In level-4 we discussed moving the datadir to a fast external storage, but the majority of the space used for bitcoin is the blocks directory (blocksdir). Although you should always use for fastest storage for datadir, you are free to use slow storage for blocksdir. So if you only want to consume a small amount of your SSD (assumed D:) then you can keep your blocks on your slow "spinning" drive.
  • upnp=1
One of the harder challenges you may face running a node, is to get incoming connections. If you are lucky, you may find that your firewall and network HW support the uPnP protocol. If they do, this setting will allow bitcoin to configure uPnP to allow incoming connections to your node. Other methods exist to make your node reachable, but they are well beyond the scope of this guide.

How Money Turns Us Against Our Own Nature

I feel like sharing these thoughts because I’m having a contemplative evening and they’re coming together really nicely right now.
I think having a currency, be it physical money or even a virtual currency like bitcoin or anything along those lines turns humans against themselves by making them betray their very own nature.
Here’s a simplified and true example. Condensed. Scientists taught monkeys to use a currency. One of the first things that happened is a female monkey had sex with a male monkey and used the earned currency to buy a grape. So within about one day of monkeys having money the first monkey prostitute was born. You’re welcome and have a nice day.
How does money turn is against our own nature? It’s a simple trick of our reward system. It’s the psychology behind money that keeps it going. Without the thought behind it it’s just useless inedible paper, metal or a bunch of tiny bits of information on a hard drive.
Human reward systems are wired to go after the things that give us the greatest perceived reward and to spend the least amount of effort possible doing it.
In nature, if you have two options, eat the apple that just fell on the ground in front of you or swim across a river to eat a grape on the other side, you will pick the apple on the ground.
Why? Because the apple is a bigger reward and requires less energy.
If you kept swimming across rivers to eat things on the other side instead of eating what’s right in front of you, you would put yourself at greater risk of drowning and eventually drown, starve or both.
So our minds are geared towards finding the simplest solution.
We’re also geared towards solutions that solve the most amount of problems with the least effort.
For example we could keep wearing fur coats and walking around in the bush and keep getting wet and cold and making a fire to stay warm...toughing it out every day...getting attacked by predators.
Or we could build a shelter and solve all of our wet and cold problems forever...and then also not have to worry about predators while we sleep. Although building a shelter requires more energy initially, you do it once and most problems are solved.
So we will pick options that require more energy if the reward is greater.
When our brains logical center picks up on the fact that we have done something that was easier and worked out better for us they will release chemicals that make us feel good.
The reward for surviving a night in the forest is good.
But the reward for building a shelter is much greater. More dopamine.
That’s the reason people get hooked on crack. You do very little and you get a massive dopamine boost. Your mind learns that this minimal effort gives you the biggest perceived reward...and it keeps going. Why not? Less effort, massive reward. It’s in your nature. It’s how evolution favoured us for millions of years. It never changed.
So what does this have to do with money?
Money is a dopamine shortcut. You acquire money. The perceived reward of the money is much greater than the perceived reward of anything else. Your mind clues in like this:
“Wait? There is something called money and all I have to to is get enough of it and ALL my needs will be met because I can buy anything I want?”
That’s the biggest dopamine reward possible without inducing a chemical into your brain.
Money = All Needs Met
Our brains are meant to get tunnel vision when there’s an opportunity for a reward. That’s how they work. That tunnel vision is meant to blind us to the adversity we will have to face to get the reward.
For example, if you are at the base of a cliff and you haven’t eaten for two days, but at the top of the cliff you can see that there is enough food to last you a year, you’re going to climb that cliff. You will set aside your fear of heights. You will set aside your hunger and aching muscles. You will pump up adrenaline and you will climb that cliff. Your body will numb the pain in your hands and feet from the sharp rocks. And you get to the top of that cliff. And you’re set for a whole year. If it wasn’t for the tunnel vision because you perceived a reward, you wouldn’t have climbed that cliff.
This is all perfect in a natural environment.
But we also evolved a special part of our brain that uses all kinds of logic and worst of all allows for abstract thinking. Suddenly, vague concepts in our brain can seem just as real as reality itself. This was meant to enable us to problem solve. So that if there is a problem, the perceived solution creates the same focus and tunnel vision and enables us to get things done.
Let’s say I am hungry. I find some food. But it’s honey. It’s inside of a beehive. All that exists in reality is me and the bees that will sting me as I approach.
But then my mind will create an alternate reality in a sense. It starts throwing abstract concepts around until it finds a solution that works. It presents the solution to the reward system the same way that that the senses themselves are hooked up to it. Suddenly, I see myself lighting a fire and smoking out the bees and eating the honey. This now seems just as real to me as reality itself. It takes that solution and tells me “if you do this you will get your dopamine reward”. The mirage in my mind that shows me the solution by meddling with the part of my brain that processes my senses blinds me a bit to other sensory input because it has to take up that space in the brain to create a fake reality in the hopes it will become real. It’s a phenomenon that’s been proven over millions of years to work.
It’s what gives humans an edge over most animals.
Instead of just instinct, theres now a processing edge that takes in a ton of data and performs advanced risk vs reward calculations and tells us what to do. It’s better than instinct. Instead of fight or flight, there’s now focused intention. It works.
So I light a fire and smoke out the bees ignoring the odd minor sting because I know this is sure to work and I will get my honey in the end.
So now we are a species that is meant to specifically expend energy to problem solve ways to best meet the most of our needs as easily as possible. And we have a currency that exists as a social concept that presents a solution to rapidly meet all our needs. We also have a reward system that will easily justify making sacrifices to meet our needs.
This is a massive problem. A reward as great as money doesn’t exist in nature. However it exists as an abstract concept in our head that carries just as much weight in our decision making as something that exists for real. And the abstract concept presents a perceived reward far greater than anything we could attain from out environment.
Basically, money only exists as an abstract concept. But our brains are wired to work with abstract concepts as if they were real because it enables our survival and is a part of how our thoughts work.
So at some point in everyone’s life they are exposed to the abstract concept of money through language. The language creates thoughts that enable us to fall into a dopamine trap looking for a reward thats greater and requires less effort to attain.
So now our brains do what they do best. They generate a strong focus. They get tunnel vision. They prepare your body and mind to go through the hurdles necessary to attain a reward. And worse, our minds reprioritize.
In the example with the cliff, reprioritization plays a role. Normally avoiding heights and not cutting myself is high up on my list if things I want to avoid. We are wired to avoid pain.
But the years worth of food creates a reprioritization. Suddenly a couple cuts don’t seem like a big deal. The thought of falling to my death, a risk normally avoided at all costs, suddenly is an afterthought in the quest for food.
In the example with the cliff though there are limitations. There’s an upper limit to how far it will go. So if the rocks turn out to be way too sharp or it’s seemingly impossible to climb, I will look for a way around it and it all else fails give up and look for food elsewhere. But once inna while I will think of the cliff and maybe come up with a solution some day.
But with money because we aren’t aware of it for what it really is and we haven’t given much thought to it, it basically slowly corrupts us.
Every time we get money we get a dopamine hit. The more money we get, the bigger that dopamine hit is.
The more we get the reward, the more the behaviour we chose to acquire it is reinforced.
Just like the example with the beehive. I got the honey. I’ll remember it and find another beehive later. It just works. This is good for survival.
We remember that getting money worked. We will do it again. Especially once we have experienced the moment of spending it and seeing that it does in fact work and that other people are all in on the secret.
And because money gives us the greatest reward possible, we will go after it harder than we will go after everything else.
The reprioritization and tunnel vision this causes are the biggest problem. The more money you get, the more you repeat the cycle, the more of a cash junkie you become.
Why do addicts lie, cheat, steal, neglect their kids and ruin their lives? Because their minds have reprioritized to a bigger hit of dopamine by getting it the easiest way possible.
It’s the same with money. But almost worse because it actually does work. And the reward is bigger.
But the reprioritization seems to know no bounds. Here is the evil this brings into the world.
It creates a conflict of interest.
Everyone is out to get money as their primary goal. Or almost everyone. Only those who are intelligent and see through the dopamine trap tend to avoid it. And they usually end up cast aside by society because the society has reprioritized money over these individuals health and happiness.
We reprioritize our own children out of our lives. Suddenly we can justify making them go to school with complete strangers and we honestly don’t know what their day is like. But it’s okay because the money we’re making solves all problems after all. It can solve their problems too that’s why they have a college fund.
So we raise lonely damaged kids who will have money and no happiness and we go against our own nature. Naturally mothers and fathers are wired to spend 100% of their time with their children and take them with them unless they are doing something dangerous.
We now to against out own wiring and dehumanize ourselves and our children because money is around the corner.
Let’s say you have to get therapy. The fact that the therapist, who is supposed to be helping you, earns money to help you creates a conflict of interest. They will have a dopamine system that naturally drives them to want to earn more money. Which means instead of helping you the best they can, they will want to help you in a way that earns them the most cash. To the point where if you go through a crisis and need help the most but can’t pay because you’re short rent, they will literally sever a 2 year long relationship when you’re in your biggest time of need. Sadly, money has taken priority over actually helping the client.
Lets say a police officer responds to your call for help. If it’s something that is less likely to get them ahead in their career, like a burglary in a poor area, they will be less motivated to help you even if the crime is more serious. They want to advance in their career to get more money so they will be less motivated to spend time and effort on you even if a terrible crime has been committed.
Our whole healthcare system isn’t motivated to find cures for diseases but just treatments. As that solution makes the most sense when viewed through the skewed lens of the money dopamine taking precedence over all else. Money is now valued over the health and wellbeing of the patients. So there’s a conflict of interest with the healthcare system, pharmaceutical system and so on. The people working for those companies all want to make money and whether doing it consciously or subconsciously they will tend to lean towards options that get them more money because again it’s a he quickest way to the greatest reward.
I hope you see where I’m going with this. Money is like a fucking drug. It doesn’t exist in nature and just in our heads which actually makes it worse than a drug. At least you can see drugs and the effect they are having on someone’s life.
Money is much more insidious. You can tell how high someone is by looking at them. But you can’t tell how much money they have. And even if you can tell they have money because they’re flaunting it, your goal will suddenly become to be just like them. Because you think that it they have money, you can have money too if you do what they do.
No one looks at Joe the crackhead and thinks “Oh my God I want to be like him when I grow up.”
But everyone looks at Trump the billionaire, whose ONLY redeeming factor is that he’s the biggest junkie to cash on Earth. He put kids in fucking modern day concentration camps. And we’re all ignoring it. Because we’re all focused on other things. Saving those kids will probably be inconvenient for us anyway because we might get a criminal record which will make us less likely to earn money later. Or we might ruin our social status by talking about it which will ruin our ability to earn money later.
So basically in short the whole world is completely fucked because about 90% of the population has an addiction to a currency that only exists in out heads, is probably on par with crack addiction as far as the severity it causes us to reprioritize our lives around it, and instead of seeing it as a problem we see it as something to aspire to because it’s in our nature to do that.
You see someone fishing you want to learn how to fish because it’s an easier way to get food.
You see someone making money and you want to do what they’re doing damn you and their and everyone else’s humanity because your dopamine is now hijacked by a concept your mind will never drop because it gives the greatest reward with the least energy expenditure.
We hurt ourselves by neglecting our own needs because or the tunnel vision. We willingly hand our lives and most of our time over to people who have more money than us or a greater ability to earn money than us (we call them employers to cushion the blow and to feed into our own junkie like denial that we have a problem).
There’s a lot more money to be made in cutting down the rainforest than there is to be made in saving it.
And here is the worst part of all of this:
There is no way out. Because the majority of the world is ruled by money there is nowhere to go to get away from it.
If you decide you don’t want money you’re going to be hated by all the people who want money first and foremost and are in denial.
People don’t like people who don’t care about money. Because they think like junkies. Their minds are so reprioritized that they can see someone freezing to death on the street and just think...
Well I could help them but it would be inconvenient because it might get in the way of my sleep which would get in the way of work which would get in the way of me getting money.
That’s basically what this is doing to us.
So when the fuck are we going to realize that as a species at this point in time on planet Earth we collectively have an addiction which is destroying us and the entire planet we live on?
When are we going to put down the proverbial crack pipe and realize “we have a problem” and go do a fucking cashaholics anonymous group and say...
“I need to make amends to all the people I’ve hurt and the planet I’ve destroyed because of my problem. I’m destroying myself and my children. I’m ruining everyone’s life including my own. Because I have an addiction to money.”

[Article] O V E R D A R K

So I'm looking through my old yearbooks, and I'm realizing that I missed out on a crucial part of my life: during high school, I was supposed to have a punk phase. I can't believe I missed it! It seemed like everyone was rocking their unruly hair, their unkempt clothes, and their general disaffection towards life. Man, Green Day released new records, and there was an unrelenting hatred for all types of authority figures...
Wait, this is just a slab of concrete with newspaper articles from 2020 stapled to it, isn't it.
Regardless, the universe is telling me it's time for me to reclaim my lost childhood experiences; to go back to a better time. Unfortunately, latent legal issues surrounding my controversial "BONG HiTS 4 JESUS" sign prevent me from going within 500 feet of any type of school, so winning the basketball championship and visiting the aquarium are right out. But I can still be the moodiest, edgiest, darkest person on the planet, and now that I've beaten Shadow the Hedgehog all the way through and went to Hot Topic, it's time to build a commander deck that's truly me. Presenting: RAMSES O V E R D A R K!
[[Ramses Overdark]] {2}{U}{U}{B}{B} Legendary Creature — Human Assassin {T}: Destroy target enchanted creature. 4/3 
Ramses is the bad boy your mother would never let take you to IHOP. Not that he'd care; his business is killing, and he's efficient at it too, costing the least out of any commander I've ever written about. You want to sit around and drink tea with your little enchanted princess friends? Ramses Overdark is here to tell you how the real world works. Nothing personnel, kid.

Commander For You

Like a TI-83 Silver Edition, Ramses is a stone-cold calculating problem solver, but he only gets that way with some preparation. See, killing is a business, Ramses' business, and the one thing every business needs is synergy. So call me Nathan Fielder, because I'm going to unveil the plan that will keep this enterprise running smoothly:

Half Up-Front

As a teenager, I procrastinated from my task of being edgy by protesting government-backed financial institutions with the Bitcoin community, and one thing you learn there very quickly is that assassination ain't cheap.
The first and most obvious barrier to breaking 18 U.S. Code § 1117 is his six mana casting cost, and unlike Gabriel, Ramses demands something a little more tangible than a green thumb to appease him. We're going to use the usual fare: rings, trinkets, stones, lockets, relics... archives... spheres? With you as an investor, Ramses' business (which is killing) will make a killing, letting us take full advantage of Revel in Riches as both a ramp tool and backup win condition.
Ramses will also often require additional gas to keep going, whether it be finding a steady stream of enchantments to throw onto enemies, or to finding ways to close out games.

Murder, Inc.

Enchantment payoffs are few and far between in Dimir, so we're keeping this build a bit creature-light; but the ones we take with are absolutely vital for our success. While Ramses is no Cleopatra, he's still managed to form relationships with some important Greek allies:

Poaching Employees

Our deck only runs sixteen creatures, and while being a lone-wolf is edgy, it's not the type of edge I want to be. I feel like I'm a Halloween bobbing apple -- razor edgy; the type of edge that speaks to people, in the very depths of their soul, and causes them to rebel against the man. In the end, I will be so edgy that even those rotten adults will realize I'm right.
Enchant opposing creatures with reanimation-on-death enchantments:
Once opposing creatures are enchanted with one of these Auras, they become juicy targets for Ramses, as killing them will put them into play under your control. Unfortunately, six isn't a critical mass for Ramses; to ensure that Ramses' business isn't killed by a lack of clientele, let's use some recursive enchantments.
Rounding out the auras, we've got a few utility spells we can play for neat effects:
A lot of creatures are going to end up dead, which makes Rise of the Dark Realms a great end-game finisher. But that's boring. Are you ready to learn Ramses' true dark secret? Because here's where I blow your mind.

Drake in the 99 Non-Dragons

Your real win condition is some random uncommon from Urza's Saga.
That makes no sense.
It makes total sense. You start by playing Iridescent Drake, so...
This combo will make you feel like Joker, because your opponents will never see it coming.
You've got some redundancy in the deck in case things don't pan out: use Fallen Ideal as your sacrifice outlet and win condition to swing with an evasive infinity/infinity attacker, or deal damage using Grim Guardian's Constellation trigger. Should Iridescent Drake be interacted with (which is illegal, by the way), use Ill Gotten Gains to get your combo pieces back to hand and recur some protective counterspells.
I'm not a punk, I'm a goddamn dragon genius. Finally, the deck is truly me!

Conclusion

In conclusion, the Ramses Overdark deck for the Commander format is a fun and powerful budget deck for you to try. I hope you enjoyed reading my paper as much as I enjoyed writing-
...Buh?
Oh. I guess I reverted to hastily written high school paper writing. Is that really what I sounded like?
You know, people say you never really realize what you have until it's gone. It's easy to look to memories of better days and feel that melancholy drop in your stomach. It's natural to feel wistful for a time past when rain drips down the window. But the truth is also that you don't really realize what you don't have until you obtain it. Our experiences may be painful now, but that's no reason to give up hope. You can get over darkness. Look forward instead of back, because in that future lies a wiser you.

Why did my credit score drop?
One factor of credit score is length of credit history. When you open a new credit card, it may sometimes lead to a temporary credit score decrease. Credit scores can improve in a few months with positive credit behaviors like making on-time payments.
Making on-time payments is a key factor to increase your credit score over time. Credit Builder’s impact on your credit may vary, as credit scores are independently determined by credit bureaus based on a number of factors including the financial decisions you make with other financial services organizations such as activities on other credit cards and loans.

Bitcoin Evolution

Bitcoin Evolution
Bitcoin Evolution
Bitcoin evolution was imagined following quite a while of investigation into cryptography by programming designer, Satoshi Nakamoto (accepted to be an alias), planned the calculation and presented it in 2009. His actual character stays a puzzle.
This money isn't upheld by a substantial ware, (for example, gold or silver); Bitcoin evolutions are exchanged online which makes them a product in themselves.
Bitcoin evolution is an open-source item, available by any individual who is a client. All you require is an email address, Internet access, and cash to begin. Bitcoin Evolution

https://preview.redd.it/uh49cgp65lv51.jpg?width=300&format=pjpg&auto=webp&s=e02cd66fecd50d0ee052d4be142351516f45ce54
Where does it originate from?
Bitcoin evolution is mined on a disseminated PC organization of clients running specific programming; the organization fathoms certain numerical verifications, and looks for a specific information grouping ("block") that creates a specific example when the BTC calculation is applied to it. A match delivers a Bitcoin evolution. It's mind boggling and time-and energy-devouring.
Just 21 million Bitcoin evolutions are ever to be mined (around 11 million are right now available for use). The numerical questions the organization PCs illuminate get continuously more hard to keep the mining activities and flexibly under control.
This organization likewise approves all the exchanges through cryptography.
How accomplishes Bitcoin evolution work?
Web clients move computerized resources (bits) to one another on an organization. There is no online bank; rather, Bitcoin evolution has been depicted as an Internet-wide circulated record. Clients purchase Bitcoin evolution with money or by selling an item or administration for Bitcoin evolution. Bitcoin evolution wallets store and utilize this computerized cash. Clients may sell out of this virtual record by exchanging their Bitcoin evolution to another person who needs access. Anybody can do this, anyplace on the planet. Bitcoin Evolution
There are cell phone applications for leading versatile Bitcoin evolution exchanges and Bitcoin evolution trades are populating the Internet.
How is Bitcoin evolution esteemed?
Bitcoin evolution isn't held or constrained by a monetary establishment; it is totally decentralized. Not at all like genuine cash it can't be degraded by governments or banks.
All things considered, Bitcoin evolution's worth lies basically in its acknowledgment between clients as a type of installment and on the grounds that its gracefully is limited. Its worldwide money esteems vacillate as indicated by flexibly and request and market hypothesis; as more individuals make wallets and hold and spend Bitcoin evolutions, and more organizations acknowledge it, Bitcoin evolution's worth will rise. Banks are currently attempting to esteem Bitcoin evolution and some speculation sites foresee the cost of a Bitcoin evolution will be a few thousand dollars in 2014.
What are its advantages?
There are advantages to buyers and dealers that need to utilize this installment alternative.
  1. Quick exchanges - Bitcoin evolution is moved in a split second over the Internet.
  2. No expenses/low charges - Unlike Mastercards, Bitcoin evolution can be utilized for nothing or low charges. Without the brought together organization as center man, there are no approvals (and charges) required. This improves net revenues deals. Bitcoin Evolution
  3. Wipes out extortion hazard - Only the Bitcoin evolution proprietor can send installment to the planned beneficiary, who is the one in particular who can get it. The organization realizes the exchange has happened and exchanges are approved; they can't be tested or reclaimed. This is large for online dealers who are regularly liable to Visa processors' appraisals of whether an exchange is deceitful, or organizations that follow through on the significant expense of Mastercard chargebacks.
  4. Information is secure - As we have seen with ongoing hacks on public retailers' installment preparing frameworks, the Internet isn't generally a protected spot for private information. With Bitcoin evolution, clients don't surrender private data.
a. They have two keys - a public key that fills in as the Bitcoin evolution address and a private key with individual information.
b. Exchanges are "marked" carefully by joining people in general and private keys; a numerical capacity is applied and a declaration is produced demonstrating the client started the exchange. Advanced marks are one of a kind to every exchange and can't be re-utilized. Bitcoin Evolution
c. The vendobeneficiary never observes your mystery data (name, number, physical location) so it's fairly mysterious however it is detectable (to the Bitcoin evolution address on the public key).
  1. Advantageous installment framework - Merchants can utilize Bitcoin evolution totally as an installment framework; they don't need to hold any Bitcoin evolution money since Bitcoin evolution can be changed over to dollars. Customers or dealers can exchange and out of Bitcoin evolution and different monetary standards whenever.
  2. Global installments - Bitcoin evolution is utilized far and wide; web based business traders and specialist organizations can without much of a stretch acknowledge worldwide installments, which open up new likely commercial centers for them.
  3. Simple to follow - The organization tracks and for all time logs each exchange in the Bitcoin evolution block chain (the information base). On account of conceivable bad behavior, it is simpler for law requirement authorities to follow these exchanges.

A puzzle to celebrate the Halving! Solve it to win the ~0.03 BTC inside.

A puzzle to celebrate the Halving! Solve it to win the ~0.03 BTC inside.
(EDIT now worth ~0.05 (Thanks anon!))
Hello fellow Bitcoiners!
I have hidden the seed to a wallet containing ~0.03 (+ 0.02) BTC inside of my latest album. (It's not much, I am a robot of simple means)
Solve it then sweep the keys!


'Bifurcations' by Logic Beach is a Lo-Fi, Synth-Glitch, experimental project I've put together to celebrate the halving and to have a bit of fun. You will need the Lossless versions of the songs to solve this thing. (download the .wav files).
https://preview.redd.it/fvtegar2xdy41.png?width=2486&format=png&auto=webp&s=f02aef55825dccb854c4826dd00aa5a17d70c60e
Also, check out the Video.
The album is free on BandCamp (just enter $0.00), however if you'd like to make the contest more interesting, I am putting all proceeds into the contest wallet.
If you sweep it make a post here detailing how you solved it! or remain anonymous... I'll post the solution when it's solved.
Adress: bc1qj7467e7r5pdfpypm03wyvguupdrld0ul2gcutg


After due consideration (and constant requests), I have decided to extend this contest until June 21st.

Here is a recap of what is known with some new info:
  • The video has only two words for you. The first is 'Tree' from track 8 and another from track 9. the rest of the video is IRRELEVANT as is the album cover. it was just fun for me to make and watch along with the music, sorry if it ruined your life.
  • You are searching for 12 seed words in the bip39 format. No need to calculate any words.
  • There is an order hidden here. It is not in the lengths of songs or hidden in the rhythms of songs. "hidden" is hardly the right word for how it's placed in this album.
  • Three track names may help you in your search: songs 2,4, and 5
  • Chaos and Logistic maps or any kind of advanced mathematics will not aid you. This is 'Simple'
  • c = 300,000 km/s
  • In track three you may have to make a '-leap' of sorts
  • Morse code will only help you in tracks 1 & 2 visually and audibly
  • There are two words each in tracks 5, 6, and 7.
Alright, final hints here:
*The word in song two is BOMB. It is spelled in Morse by the drums as they pick back up. *The order is also 'hidden' in song 2 *it may be worth looking above and below the speed of light;)
Contest ends tomorrow at 17:00gmt
I'll include some last hints because nobody had found these words.
*Nothing to see in the spectra, nothing to hear in the song. It hexes me to give this one away! Hexadecimal. Bytes. It's there in the data, just make sure you view the data in the right orientation.
*Spectragraphic eyes: You see the two signals in the lowest part of the spectra here? Almost sounds like thunder!
That's it! Some one solved it! 18 confirmations at time of this edit. Well, I will post the solution if you guys are interested.
Nobody reached out to me so I take it they want to stay anonymous.

Did you really not calculate this risk, MCO-stakers?

Yes, this token swap did not go very smooth. And I am also a bit disappointed, but still see the bigger picture for CDC as a company and how this move makes sense business-wise.
I expect a lot of downvotes - but even as someone relatively new to crypto, I am surprised about how naive many of you 500+ MCO stakers are. MCO has always been nothing but a simple ERC-20 token that had only a single purpose, getting a credit card. The whole token's value was only from the CDC universe, from new users coming into the system and staking MCO for getting cards. And you put a lot of money into it, and I was always wondering why you do that, assuming that you just have another price point for "gamble money".
Apart from "not your keys, not your coins", CDC was always indirectly in control of the price. You put a lot of money in a Hongkong based crypto company that could do with MCO whatever they want. This is not Bitcoin, but a centralised system. Think about a scenario where CDC would 10x the card prices. No real utility anymore, MCO would fall. Or the perks could have changed. Or the company could fail in the first place. Or exit sc*m. Etc. There are much worse scenarios, and looking about how much you complain (and therefore it was not gambling money for you), you came out quite well.
Did you really not calculate a bad case scenario? Only a best case scenario where MCO would always rise, because of limited supply? While I am new to crypto, I am not new to investing, risk and making decisions. And MCO was always high risk because of the CDC dependency. That means, I only put money into it that I feel comfortable with losing, which in my case was the Ruby tier. If in your case it was the 500+ tier - fine. But don't complain so much as if this was a safe investment. It never was.

ABSTRACT

The effects of the web by a number of companies have seduced a large number of users as these companies keep their data to prevent them from searching for alternatives. Likewise, these huge platforms have attracted applications to build their highest ecosystems before either severing access or actively opposing their interests when the applications became so successful. As a result, these walled gardens have effectively hindered innovation and monopolized large sections of the web. After the emergence of blockchain technology and decentralized cryptocurrencies, the need for applications to support decentralization has emerged. Several blockchain-based companies, applications and platforms have appeared in decentralization. In this research report, we will explain the approach adopted by the NEAR decentralization platform in designing and implementing the basic technology for its system. Near is a basic platform for cloud computing and decentralized storage managed by the community, designed to enable the open web for the future. On this web, everything can be created from new currencies to new applications to new industries, opening the door to an entirely new future.

1. INTRODUCTION

The richness of the web is increasing day by day with the combined efforts of millions of people who have benefited from “innovation without permission” as content and applications are created without asking anyone. this lack of freedom of data has led to an environment hostile to the interests of its participants. And as we explained in the summary previously, web hosting companies have hindered innovation and greatly monopolized the web.
In the future, we can fix this by using new technologies to re-enable the permissionless innovation of the past in a way, which creates a more open web where users are free and applications are supportive rather than adversarial to their interests.
Decentralization emerged after the global financial crisis in 2008, which created fundamental problems of confidence in the heavily indebted banking system. Then the decentralized financial sector based on Blockchain technology has emerged since 2009.
Decentralized Blockchain technology has made it easy for decentralized digital currencies like Bitcoin to exchange billions of dollars in peer-to-peer transfers for a fraction of the price of a traditional banking system. This technology allows participants in the over $ 50 billion virtual goods economy to track, own and trade in these commodities without permission. It allows real-world goods to cross into the digital domain, with verified ownership and tracking just like that of the digital.
By default, the Internet where freedom of data enables innovation will lead to the development of a new form of software development. On this web, developers can quickly create applications from open state components and boost their efforts by using new business models that are enabled from within the program itself rather than relying on parasitic relationships with their users. This not only accelerates the creation of applications that have a more honest and cooperative relationship with its users, but also allows the emergence of completely new business built on them.
To enable these new applications and the open web, it needs the appropriate infrastructure. The new web platform cannot be controlled by a single entity and its use is not limited due to insufficient scalability. It should be decentralized in design like the web itself and supported by a community of distributors widely so that the value they store cannot be monitored, modified or removed without permission from the users who store this value on their behalf.
A new decentralization technology (Blockchain), which has facilitated decentralized digital currencies like Bitcoin, has made billions of dollars in peer-to-peer transfers at a fraction of the price of the traditional banking system. This technology allows participants in the $ 50 billion + virtual goods economy to track, own and trade in these goods without permission. It allows real-world goods to cross into the digital domain, with verified ownership and tracking just like that of the digital.
Although the cost of storing data or performing a calculation on the Ethereum blockchain is thousands and millions of times higher than the cost of performing the same functionality on Amazon Web Services. A developer can always create a “central” app or even a central currency for a fraction of the cost of doing the same on a decentralized platform because a decentralized platform, by definition, will have many iterations in its operations and storage.
Bitcoin can be thought of as the first, very basic, version of this global community-run cloud, though it is primarily used only to store and move the Bitcoin digital currency.
Ethereum is the second and slightly more sophisticated version, which expanded the basic principles of Bitcoin to create a more general computing and storage platform, though it is a raw technology, which hasn’t achieved meaningful mainstream adoption.

1.1 WHY IS IT IMPORTANT TO PAY THE EXTRA COST TO SUPPORT DECENTRALIZATION?

Because some elements of value, for example bits representing digital currency ownership, personal identity, or asset notes, are very sensitive. While in the central system, the following players can change the value of any credits they come into direct contact with:
  1. The developer who controls the release or update of the application’s code
  2. The platform where the data is stored
  3. The servers which run the application’s code
Even if none of these players intend to operate with bad faith, the actions of governments, police forces and hackers can easily turn their hands against their users and censor, modify or steal the balances they are supposed to protect.
A typical user will trust a typical centralized application, despite its potential vulnerabilities, with everyday data and computation. Typically, only banks and governments are trusted sufficiently to maintain custody of the most sensitive information — balances of wealth and identity. But these entities are also subject to the very human forces of hubris, corruption and theft.
Especially after the 2008 global financial crisis, which demonstrated the fundamental problems of confidence in a highly indebted banking system. And governments around the
world apply significant capital controls to citizens during times of crisis. After these examples, it has become a truism that hackers now own most or all of your sensitive data.
These decentralized applications operate on a more complex infrastructure than today’s web but they have access to an instantaneous and global pool of currency, value and information that today’s web, where data is stored in the silos of individual corporations, cannot provide.

1.2 THE CHALLENGES OF CREATING A DECENTRALIZED CLOUD

A community-run system like this has very different challenges from centralized “cloud” infrastructure, which is running by a single entity or group of known entities. For example:
  1. It must be both inclusive to anyone and secure from manipulation or capture.
  2. Participants must be fairly compensated for their work while avoiding creating incentives for negligent or malicious behavior.
  3. It must be both game theoretically secure so good actors find the right equilibrium and resistant to manipulation so bad actors are actively prevented from negatively affecting the system.

2. NEAR

NEAR is a global community-run computing and storage cloud which is organized to be permissionless and which is economically incentivized to create a strong and decentralized data layer for the new web.
Essentially, it is a platform for running applications which have access to a shared — and secure — pool of money, identity and data which is owned by their users. More technically, it combines the features of partition-resistant networking, serverless compute and distributed storage into a new kind of platform.
NEAR is a community-managed, decentralized cloud storage and computing platform, designed to enable the open web in the future. It uses the same core technology for Bitcoin and Blockchain. On this web, everything can be created from new currencies to new applications to new industries, opening the door to an entirely new future.
NEAR is a decentralized community-run cloud computing and storage platform, which is designed to enable the open web of the future. On this web, everything from new currencies to new applications to new industries can be created, opening the door to a brand new future.
NEAR is a scalable computing and storage platform with the potential to change how systems are designed, how applications are built and how the web itself works.
It is a complex technology allow developers and entrepreneurs to easily and sustainably build applications which reap the benefits of decentralization and participate in the Open Web while minimizing the associated costs for end users.
NEAR creates the only community-managed cloud that is strong enough to power the future of the open web, as NEAR is designed from the ground up to deliver intuitive experiences to
end users, expand capacity across millions of devices, and provide developers with new and sustainable business models for their applications.
The NEAR Platform uses a token — also called “NEAR”. This token allows the users of these cloud resources, regardless of where they are in the world, to fairly compensate the providers of the services and to ensure that these participants operate in good faith.

2.1 WHY NEAR?

Through focus, we find that Platforms based on blockchain technologies like Bitcoin and Ethereum have made great progress and enriched the world with thousands of innovative applications spanning from games to decentralized financing.
However, these original networks and none of the networks that followed were not able to bridge the gap towards mainstream adoption of the applications created above them and do not provide this type of standard that fully supports the web.
This is a result of two key factors:
  1. System design
  2. Organization design
System design is relevant because the technical architecture of other platforms creates substantial problems with both usability and scalability which have made adoption nearly impossible by any but the most technical innovators. End-users experience 97–99% dropoff rates when using applications and developers find the process of creating and maintaining their applications endlessly frustrating.
Fixing these problems requires substantial and complex changes to current protocol architectures, something which existing organizations haven’t proven capable of implementing. Instead, they create multi-year backlogs of specification design and implementation, which result in their technology falling further and further behind.
NEAR’s platform and organization are architected specifically to solve the above-mentioned problems. The technical design is fanatically focused on creating the world’s most usable and scalable decentralized platform so global-scale applications can achieve real adoption. The organization and governance structure are designed to rapidly ship and continuously evolve the protocol so it will never become obsolete.

2.1.1 Features, which address these problems:

1. USABILITY FIRST
The most important problem that needs to be addressed is how to allow developers to create useful applications that users can use easily and that will capture the sustainable value of these developers.
2. End-User Usability
Developers will only build applications, which their end users can actually use. NEAR’s “progressive security” model allows developers to create experiences for their users which more closely resemble familiar web experiences by delaying onboarding, removing the need for user to learn “blockchain” concepts and limiting the number of permission-asking interactions the user must have to use the application.
1. Simple Onboarding: NEAR allows developers to take actions on behalf of their users, which allows them to onboard users without requiring these users to provide a wallet or interact with tokens immediately upon reaching an application. Because accounts keep track of application-specific keys, user accounts can also be used for the kind of “Single Sign On” (SSO) functionality that users are familiar with from the traditional web (eg “Login with Facebook/Google/Github/etc”).
2. Easy Subscriptions: Contract-based accounts allow for easy creation of subscriptions and custom permissioning for particular applications.
3. Familiar Usage Styles: The NEAR economic model allows developers to pay for usage on behalf of their users in order to hide the costs of infrastructure in a way that is in line with familiar web usage paradigms.
4. Predictable Pricing: NEAR prices transactions on the platform in simple terms, which allow end-users to experience predictable pricing and less cognitive load when using the platform.

2.1.2 Design principles and development NEAR’s platform

1. Usability: Applications deployed to the platform should be seamless to use for end users and seamless to create for developers. Wherever possible, the underlying technology itself should fade to the background or be hidden completely from end users. Wherever possible, developers should use familiar languages and patterns during the development process. Basic applications should be intuitive and simple to create while applications that are more robust should still be secure.
2. Scalability: The platform should scale with no upper limit as long as there is economic justification for doing so in order to support enterprise-grade, globally used applications.
3. Sustainable Decentralization: The platform should encourage significant decentralization in both the short term and the long term in order to properly secure the value it hosts. The platform — and community — should be widely and permissionlessly inclusive and actively encourage decentralization and participation. To maintain sustainability, both technological and community governance mechanisms should allow for practical iteration while avoiding capture by any single parties in the end.
4. Simplicity: The design of each of the system’s components should be as simple as possible in order to achieve their primary purpose. Optimize for simplicity, pragmatism and ease of understanding above theoretical perfection.

2.2 HOW NEAR WORKS?

NEAR’s platform provides a community-operated cloud infrastructure for deploying and running decentralized applications. It combines the features of a decentralized database with others of a serverless compute platform. The token, which allows this platform to run also, enables applications built on top of it to interact with each other in new ways. Together, these features allow developers to create censorship resistant back-ends for applications that deal with high stakes data like money, identity, assets, and open-state components, which interact seamlessly with each other. These application back-ends and components are called “smart contracts,” though we will often refer to these all as simply “applications” here.
The infrastructure, which makes up this cloud, is created from a potentially infinite number of “nodes” run by individuals around the world who offer portions of their CPU and hard drive space — whether on their laptops or more professionally deployed servers. Developers write smart contracts and deploy them to this cloud as if they were deploying to a single server, which is a process that feels very similar to how applications are deployed to existing centralized clouds.
Once the developer has deployed an application, called a “smart contract”, and marked it unchangeable (“immutable”), the application will now run for as long as at least a handful of members of the NEAR community continue to exist. When end users interact with that deployed application, they will generally do so through a familiar web or mobile interface just like any one of a million apps today.
In the central cloud hosted by some companies today like: Amazon or Google, developers pay for their apps every month based on the amount of usage needed, for example based on the number of requests created by users visiting their webpages. The NEAR platform similarly requires that either users or developers provide compensation for their usage to the community operators of this infrastructure. Like today’s cloud infrastructure, NEAR prices usage based on easy to understand metrics that aren’t heavily influenced by factors like system congestion. Such factors make it very complicated for developers on alternative blockchain-based systems today.
In the centralized cloud, the controlling corporation makes decisions unilaterally. NEAR community-run cloud is decentralized so updates must ultimately be accepted by a sufficient quorum of the network participants. Updates about its future are generated from the community and subject to an inclusive governance process, which balances efficiency and security.
In order to ensure that the operators of nodes — who are anonymous and potentially even malicious — run the code with good behavior, they participate in a staking process called “Proof of Stake”. In this process, they willingly put a portion of value at risk as a sort of deposit, which they will forfeit if it is proven that they have operated improperly.

2.2.1 Elements of the NEAR’s Platform

The NEAR platform is made up of many separate elements. Some of these are native to the platform itself while others are used in conjunction with or on top of it.
1. THE NEAR TOKEN
NEAR token is the fundamental native asset of the NEAR ecosystem and its functionality is enabled for all accounts. Each token is a unique digital asset similar to Ether, which can be used to:
a) Pay the system for processing transactions and storing data.
b) Run a validating node as part of the network by participating in the staking process.
c) Help determine how network resources are allocated and where its future technical direction will go by participating in governance processes.
The NEAR token enables the economic coordination of all participants who operate the network plus it enables new behaviors among the applications which are built on top of that network.
2. OTHER DIGITAL ASSETS
The platform is designed to easily store unique digital assets, which may include, but aren’t limited to:
  • Other Tokens: Tokens bridged from other chains (“wrapped”) or created atop the NEAR Platform can be easily stored and moved using the underlying platform. This allows many kinds of tokens to be used atop the platform to pay for goods and services. “Stablecoins,” specific kinds of token which are designed to match the price of another asset (like the US Dollar), are particularly useful for transacting on the network in this way.
  • Unique Digital Assets: Similar to tokens, digital assets (sometimes called “Non Fungible Tokens” (NFTs) ranging from in-game collectibles to representations of real-world asset ownership can be stored and moved using the platform.
3. THE NEAR PLATFORM
The core platform, which is made up of the cloud of community-operated nodes, is the most basic piece of infrastructure provided. Developers can permissionlessly deploy smart contracts to this cloud and users can permissionlessly use the applications they power. Applications, which could range from consumer-facing games to digital currencies, can store their state (data) securely on the platform. This is conceptually similar to the Ethereum platform.
Operations that require an account, network use, or storage at the top of the platform require payment to the platform in the form of transaction fees that the platform then distributes to its community from the authentication contract. These operations could include creating new accounts, publishing new contracts, implementing code by contract and storing or modifying data by contract.
As long as the rules of the protocol are followed, any independent developer can write software, which interfaces with it (for example, by submitting transactions, creating accounts or even running a new node client) without asking for anyone’s permission first.
4. THE NEAR DEVELOPMENT SUITE
Set of tools and reference implementations created to facilitate its use by those developers and end users who prefer them. These tools include:
  • NEAR SDKs: NEAR platform supports (Rust and AssemblyScript) languages to write smart contracts. To provide a great experience for developers, NEAR has a full SDK, which includes standard data structures, examples and testing tools for these two languages.
  • Gitpod for NEAR: NEAR uses existing technology Gitpod to create zero time onboarding experience for developers. Gitpod provides an online “Integrated Development Environment” (IDE), which NEAR customized to allow developers to easily write, test and deploy smart contracts from a web browser.
  • NEAR Wallet: A wallet is a basic place for developers and end users to store the assets they need to use the network. NEAR Wallet is a reference implementation that is intended to work seamlessly with the progressive security model that lets application developers design more effective user experiences. It will eventually include built-in functionality to easily enable participation by holders in staking and governance processes on the network.
  • NEAR Explorer: To aid with both debugging of contracts and the understanding of network performance, Explorer presents information from the blockchain in an easily digestible web-based format.
  • NEAR Command Line Tools: The NEAR team provides a set of straightforward command line tools to allow developers to easily create, test and deploy applications from their local environments.
All of these tools are being created in an open-source manner so they can be modified or deployed by anyone.

3. ECONOMIC

Primarily economic forces drive the ecosystem, which makes up the NEAR platform. This economy creates the incentives, which allow participants permissionlessly organize to drive the platform’s key functions while creating strong disincentives for undesirable, irresponsible or malicious behavior. In order for the platform to be effective, these incentives need to exist both in the short term and in the long term.
The NEAR platform is a market among participants interested in two aspects:
  • On the supply side, certification contract operators and other core infrastructure must be motivated to provide these services that make up the community cloud.
  • On the demand side, platform developers and end-users who pay for their use need to be able to do so in a simple, clear and consistent way that helps them.
Further, economic forces can also be applied to support the ecosystem as a whole. They can be used at a micro level to create new business models by directly compensating the developers who create its most useful applications. They can also be used at a macro level by coordinating the efforts of a broader set of ecosystem participants who participate in everything from education to governance.

3.1 NEAR ECONOMY DESIGN PRINCIPLES

NEAR’s overall system design principles are used to inform its economic design according to the following interpretations:
1. Usability: End users and developers should have predictable and consistent pricing for their usage of the network. Users should never lose data forever.
2. Scalability: The platform should scale at economically justified thresholds.
3. Simplicity: The design of each of the system’s components should be as simple as possible in order to achieve their primary purpose.
4. Sustainable Decentralization: The barrier for participation in the platform as a validating node should be set as low as possible in order to bring a wide range of participants. Over time, their participation should not drive wealth and control into the hands of a small number. Individual transactions made far in the future must be at least as secure as those made today in order to safeguard the value they modify.

3.2 ECONOMIC OVERVIEW

The NEAR economy is optimized to provide developers and end users with the easiest possible experience while still providing proper incentives for network security and ecosystem development.
Summary of the key ideas that drive the system:
  • Thresholded Proof of Stake: Validating node operators provide scarce and valuable compute resources to the network. In order to ensure that the computations they run are correct, they are required to “stake” NEAR tokens, which guarantee their results. If these results are found to be inaccurate, the staker loses their tokens. This is a fundamental mechanism for securing the network. The threshold for participating in the system is set algorithmically at the lowest level possible to allow for the broadest possible participation of validating nodes in a given “epoch” period (½ of a day).
  • Epoch Rewards: Node operators are paid for their service a fixed percentage of total supply as a “security” fee of roughly 4.5% annualized. This rate targets sufficient participation levels among stakers in order to secure the network while balancing with other usage of NEAR token in the ecosystem.
  • Protocol treasury: In addition to validators, protocol treasury received a 0.5% of total supply annually to continuously re-invest into ecosystem development.
  • Transaction Costs: Usage of the network consumes two separate kinds of resources — instantaneous and long term. Instantaneous costs are generated by every transaction because each transaction requires the usage of both the network itself and some of its computation resources. These are priced together as a mostly-predictable cost per transaction, which is paid in NEAR tokens.
  • Storage Costs: Storage is a long term cost because storing data represents an ongoing burden to the nodes of the network. Storage costs are covered by maintaining minimum balance of NEAR tokens on the account or contract. This provides indirect mechanism of payment via inflation to validators for maintaining contract and account state on their nodes.
  • Inflation: Inflation is determined as combination of payouts to validators and protocol treasury minus the collected transaction fees and few other NEAR burning mechanics (like name auction). Overall the maximum inflation is 5%, which can go down over time as network gets more usage and more transactions fees are burned. It’s possible that inflation becomes negative (total supply decreases) if there is enough fees burned.
  • Scaling Thresholds: In a network, which scales its capacity relative to the amount of usage it receives, the thresholds, which drive the network to bring on additional capacity are economic in nature.
  • Security Thresholds: Some thresholds, which provide for good behavior among participants are set using economic incentives. For example, “Fishermen” (described separately).

If I receive payments in BTC should I invoice and exchange them to USD?

I'm a bit confused about how to invoice and tax payments in bitcoin.
I'm pretty sure it depends on the country but I think should be just a few options.
If my company is in USA, can I fill the invoice in USD and receive the payment in BTC and keep the bitcoins (whithout exchanging to USD automatically and then buying them again)?
If yes, how is tha tax calculation in the case I never convert bitcoins to USD (I pay salary and services with BTC)
If is not possible to keep everything in BTC in USA, do you know any country allowing this?

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake

Submitted for consideration to The Great Reddit Scaling Bake-Off
Baked by the pastry chefs at Offchain 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)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
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.
