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.

This November...

Let's set aside the tickename issue for a second and think as scientists about the upcoming experiment. Assuming there will be a split, I think it's going to be interesting. (If the split is somehow avoided, then all of the following makes no sense, of course)
I frankly think the experiment of "hashrate-funded centrally-developed Bitcoin Cash" vs "hodler-funded multi-team-developed Bitcoin Cash" is very interesting. I don't mean "centrally-developed" as an offence here, it's just a fact - ABC will be developing it.
Before you start throwing in tomatos, let's think about it.
We all have front-row seats - each gets equal amount of both coins, so either coin wins - you have your cut.
It might even be that BOTH coins will be winners, since unlike the BSV situation, this is going to be probably developed under MIT license, so either side can copy code from other side. (Unless, of course, ABC goes BSV-way and protects their code with a restrictive license, while the other side will be using MIT/BSD licenses for sure)
Let's consider both sides' pros and cons.

ABC side

I don't really like IFP, but I think what Amaury did was pretty clever and worth considering. With this plan he gets to control his coin fully and impose any rules he sees as best for his coin, be it drift correction, 6-month releases or whatever else. He believes in his power to make this coin the best, so let's see if he can.
[+] Corporations are often pretty efficient at what they do. Usually, with capitalism and democracy they will perfect their game like no one, because of competition.
[-] But this won't be exactly like capitalism, more like socialism, because ABC/Amaury will get paid no matter their performance. They will always get 8%. That makes people lazy. Why bother if you get your salary anyway?
[+] ABC has a track record of 3 years and BCH didn't die, which gives them some credit that they could do it.
[+] Amaury and ABC will get paid in their own coin, so the more valuable it is, the richer they get. (Unless they sell for USD immediately) Also, they will get close to $8 million in funding in first year alone (at the current price), which would allow him to hire, well, best of the best in their class (cryptographers, developers, etc...). Amaury knows that and he's right - developers are freaking expensive ($100,000+/year). (Well, again, assuming Amaury will be hiring...)
[-] They don't have to listen to the community, so they have no force feedback if what they do is of any value or is it a useless distraction.

BCHN + others

[+] Hodler-funded means that you don't get paid unless you promise to deliver useful value and have proven to provide value in the past. So you have to perfect your game always - that's much closer to capitalism.
[-] Very hard to raise funds. Amaury will get $8m/year while BCHN and other nodes barely managed to collect $100-200K, probably for the next year or so. Hodlers don't want to give away their money too much, because it might 10x or 20x in very short amount of time.
[+] If BCHN/other nodes do their job well and the coin value raise - their money becomes more valuable, so $100K might become $1M in a year. Assuming they haven't sold for USD. Something tells me they didn't.
[-] Grass-roots things can be short-lived. People are free to join and leave any time, so eventually you get tired of everything.

Potential problems with the experiment

  1. Tickename, obviously pretty bad issue;
  2. Reputation/community loss (BCH splitting again);
  3. Confusion for next few years about what Bitcoin Cash is (just like it was with BCH/BTC split);
  4. No replay protection (this one is nasty), so it's hard to split your money at fork time, you need to wait to get some miner dust to mix in with your coins to split them properly;
  5. Potential that one side might be without wallets at first (i.e. if all wallets and services like Fountainhead/rest.bitcoin.com, which are used by wallets, leave ABC - how would you transfer your money?) - that surely will be a blow, but it's fixable. BCH started this way too.
  6. EDIT: Merchant dis-adoption. Many will be tired of non-stop drama and leave. Maybe, stability of BCHN site will lure some back later. (comment about this)
I don't see miners as an issue (I explained why here and here)
I'm actually curious. Whether corporate efficiency (but with a bit of socialism) or grass-roots (barely with any funding in comparison) will get ahead.
Even though there is already a similar experiment going (BSV), but it's still interesting - each corporation is different and where Apple succeeded, many other phone/computer companies failed. Is listening to market critical? Remember Henry Ford: "If I had asked people what they wanted, they would have said faster horses." On the other hand we have plenty of coins with a lot of funding not even in Top 10.
Get your tickets (coins) ready, we're in for a ride!

How EpiK Protocol “Saved the Miners” from Filecoin with the E2P Storage Model?

How EpiK Protocol “Saved the Miners” from Filecoin with the E2P Storage Model?

https://preview.redd.it/n5jzxozn27v51.png?width=2222&format=png&auto=webp&s=6cd6bd726582bbe2c595e1e467aeb3fc8aabe36f
On October 20, Eric Yao, Head of EpiK China, and Leo, Co-Founder & CTO of EpiK, visited Deep Chain Online Salon, and discussed “How EpiK saved the miners eliminated by Filecoin by launching E2P storage model”. ‘?” The following is a transcript of the sharing.
Sharing Session
Eric: Hello, everyone, I’m Eric, graduated from School of Information Science, Tsinghua University. My Master’s research was on data storage and big data computing, and I published a number of industry top conference papers.
Since 2013, I have invested in Bitcoin, Ethereum, Ripple, Dogcoin, EOS and other well-known blockchain projects, and have been settling in the chain circle as an early technology-based investor and industry observer with 2 years of blockchain experience. I am also a blockchain community initiator and technology evangelist
Leo: Hi, I’m Leo, I’m the CTO of EpiK. Before I got involved in founding EpiK, I spent 3 to 4 years working on blockchain, public chain, wallets, browsers, decentralized exchanges, task distribution platforms, smart contracts, etc., and I’ve made some great products. EpiK is an answer to the question we’ve been asking for years about how blockchain should be landed, and we hope that EpiK is fortunate enough to be an answer for you as well.
Q & A
Deep Chain Finance:
First of all, let me ask Eric, on October 15, Filecoin’s main website launched, which aroused everyone’s attention, but at the same time, the calls for fork within Filecoin never stopped. The EpiK protocol is one of them. What I want to know is, what kind of project is EpiK Protocol? For what reason did you choose to fork in the first place? What are the differences between the forked project and Filecoin itself?
Eric:
First of all, let me answer the first question, what kind of project is EpiK Protocol.
With the Fourth Industrial Revolution already upon us, comprehensive intelligence is one of the core goals of this stage, and the key to comprehensive intelligence is how to make machines understand what humans know and learn new knowledge based on what they already know. And the knowledge graph scale is a key step towards full intelligence.
In order to solve the many challenges of building large-scale knowledge graphs, the EpiK Protocol was born. EpiK Protocol is a decentralized, hyper-scale knowledge graph that organizes and incentivizes knowledge through decentralized storage technology, decentralized autonomous organizations, and generalized economic models. Members of the global community will expand the horizons of artificial intelligence into a smarter future by organizing all areas of human knowledge into a knowledge map that will be shared and continuously updated for the eternal knowledge vault of humanity
And then, for what reason was the fork chosen in the first place?
EpiK’s project founders are all senior blockchain industry practitioners and have been closely following the industry development and application scenarios, among which decentralized storage is a very fresh application scenario.
However, in the development process of Filecoin, the team found that due to some design mechanisms and historical reasons, the team found that Filecoin had some deviations from the original intention of the project at that time, such as the overly harsh penalty mechanism triggered by the threat to weaken security, and the emergence of the computing power competition leading to the emergence of computing power monopoly by large miners, thus monopolizing the packaging rights, which can be brushed with computing power by uploading useless data themselves.
The emergence of these problems will cause the data environment on Filecoin to get worse and worse, which will lead to the lack of real value of the data in the chain, high data redundancy, and the difficulty of commercializing the project to land.
After paying attention to the above problems, the project owner proposes to introduce multi-party roles and a decentralized collaboration platform DAO to ensure the high value of the data on the chain through a reasonable economic model and incentive mechanism, and store the high-value data: knowledge graph on the blockchain through decentralized storage, so that the lack of value of the data on the chain and the monopoly of large miners’ computing power can be solved to a large extent.
Finally, what differences exist between the forked project and Filecoin itself?
On the basis of the above-mentioned issues, EpiK’s design is very different from Filecoin, first of all, EpiK is more focused in terms of business model, and it faces a different market and track from the cloud storage market where Filecoin is located because decentralized storage has no advantage over professional centralized cloud storage in terms of storage cost and user experience.
EpiK focuses on building a decentralized knowledge graph, which reduces data redundancy and safeguards the value of data in the distributed storage chain while preventing the knowledge graph from being tampered with by a few people, thus making the commercialization of the entire project reasonable and feasible.
From the perspective of ecological construction, EpiK treats miners more friendly and solves the pain point of Filecoin to a large extent, firstly, it changes the storage collateral and commitment collateral of Filecoin to one-time collateral.
Miners participating in EpiK Protocol are only required to pledge 1000 EPK per miner, and only once before mining, not in each sector.
What is the concept of 1000 EPKs, you only need to participate in pre-mining for about 50 days to get this portion of the tokens used for pledging. The EPK pre-mining campaign is currently underway, and it runs from early September to December, with a daily release of 50,000 ERC-20 standard EPKs, and the pre-mining nodes whose applications are approved will divide these tokens according to the mining ratio of the day, and these tokens can be exchanged 1:1 directly after they are launched on the main network. This move will continue to expand the number of miners eligible to participate in EPK mining.
Secondly, EpiK has a more lenient penalty mechanism, which is different from Filecoin’s official consensus, storage and contract penalties, because the protocol can only be uploaded by field experts, which is the “Expert to Person” mode. Every miner needs to be backed up, which means that if one or more miners are offline in the network, it will not have much impact on the network, and the miner who fails to upload the proof of time and space in time due to being offline will only be forfeited by the authorities for the effective computing power of this sector, not forfeiting the pledged coins.
If the miner can re-submit the proof of time and space within 28 days, he will regain the power.
Unlike Filecoin’s 32GB sectors, EpiK’s encapsulated sectors are smaller, only 8M each, which will solve Filecoin’s sector space wastage problem to a great extent, and all miners have the opportunity to complete the fast encapsulation, which is very friendly to miners with small computing power.
The data and quality constraints will also ensure that the effective computing power gap between large and small miners will not be closed.
Finally, unlike Filecoin’s P2P data uploading model, EpiK changes the data uploading and maintenance to E2P uploading, that is, field experts upload and ensure the quality and value of the data on the chain, and at the same time introduce the game relationship between data storage roles and data generation roles through a rational economic model to ensure the stability of the whole system and the continuous high-quality output of the data on the chain.
Deep Chain Finance:
Eric, on the eve of Filecoin’s mainline launch, issues such as Filecoin’s pre-collateral have aroused a lot of controversy among the miners. In your opinion, what kind of impact will Filecoin bring to itself and the whole distributed storage ecosystem after it launches? Do you think that the current confusing FIL prices are reasonable and what should be the normal price of FIL?
Eric:
Filecoin mainnet has launched and many potential problems have been exposed, such as the aforementioned high pre-security problem, the storage resource waste and computing power monopoly caused by unreasonable sector encapsulation, and the harsh penalty mechanism, etc. These problems are quite serious, and will greatly affect the development of Filecoin ecology.
These problems are relatively serious, and will greatly affect the development of Filecoin ecology, here are two examples to illustrate. For example, the problem of big miners computing power monopoly, now after the big miners have monopolized computing power, there will be a very delicate state — — the miners save a file data with ordinary users. There is no way to verify this matter in the chain, whether what he saved is uploaded by himself or someone else. And after the big miners have monopolized computing power, there will be a very delicate state — — the miners will save a file data with ordinary users, there is no way to verify this matter in the chain, whether what he saved is uploaded by himself or someone else. Because I can fake another identity to upload data for myself, but that leads to the fact that for any miner I go to choose which data to save. I have only one goal, and that is to brush my computing power and how fast I can brush my computing power.
There is no difference between saving other people’s data and saving my own data in the matter of computing power. When I save someone else’s data, I don’t know that data. Somewhere in the world, the bandwidth quality between me and him may not be good enough.
The best option is to store my own local data, which makes sense, and that results in no one being able to store data on the chain at all. They only store their own data, because it’s the most economical for them, and the network has essentially no storage utility, no one is providing storage for the masses of retail users.
The harsh penalty mechanism will also severely deplete the miner’s profits, because DDOS attacks are actually a very common attack technique for the attacker, and for a big miner, he can get a very high profit in a short period of time if he attacks other customers, and this thing is a profitable thing for all big miners.
Now as far as the status quo is concerned, the vast majority of miners are actually not very well maintained, so they are not very well protected against these low-DDOS attacks. So the penalty regime is grim for them.
The contradiction between the unreasonable system and the demand will inevitably lead to the evolution of the system in a more reasonable direction, so there will be many forked projects that are more reasonable in terms of mechanism, thus attracting Filecoin miners and a diversion of storage power.
Since each project is in the field of decentralized storage track, the demand for miners is similar or even compatible with each other, so miners will tend to fork the projects with better economic benefits and business scenarios, so as to filter out the projects with real value on the ground.
For the chaotic FIL price, because FIL is also a project that has gone through several years, carrying too many expectations, so it can only be said that the current situation has its own reasons for existence. As for the reasonable price of FIL there is no way to make a prediction because in the long run, it is necessary to consider the commercialization of the project to land and the value of the actual chain of data. In other words, we need to keep observing whether Filecoin will become a game of computing power or a real value carrier.
Deep Chain Finance:
Leo, we just mentioned that the pre-collateral issue of Filecoin caused the dissatisfaction of miners, and after Filecoin launches on the main website, the second round of space race test coins were directly turned into real coins, and the official selling of FIL hit the market phenomenon, so many miners said they were betrayed. What I want to know is, EpiK’s main motto is “save the miners eliminated by Filecoin”, how to deal with the various problems of Filecoin, and how will EpiK achieve “save”?
Leo:
Originally Filecoin’s tacit approval of the computing power makeup behavior was to declare that the official directly chose to abandon the small miners. And this test coin turned real coin also hurt the interests of the loyal big miners in one cut, we do not know why these low-level problems, we can only regret.
EpiK didn’t do it to fork Filecoin, but because EpiK to build a shared knowledge graph ecology, had to integrate decentralized storage in, so the most hardcore Filecoin’s PoRep and PoSt decentralized verification technology was chosen. In order to ensure the quality of knowledge graph data, EpiK only allows community-voted field experts to upload data, so EpiK naturally prevents miners from making up computing power, and there is no reason for the data that has no value to take up such an expensive decentralized storage resource.
With the inability to make up computing power, the difference between big miners and small miners is minimal when the amount of knowledge graph data is small.
We can’t say that we can save the big miners, but we are definitely the optimal choice for the small miners who are currently in the market to be eliminated by Filecoin.
Deep Chain Finance:
Let me ask Eric: According to EpiK protocol, EpiK adopts the E2P model, which allows only experts in the field who are voted to upload their data. This is very different from Filecoin’s P2P model, which allows individuals to upload data as they wish. In your opinion, what are the advantages of the E2P model? If only voted experts can upload data, does that mean that the EpiK protocol is not available to everyone?
Eric:
First, let me explain the advantages of the E2P model over the P2P model.
There are five roles in the DAO ecosystem: miner, coin holder, field expert, bounty hunter and gateway. These five roles allocate the EPKs generated every day when the main network is launched.
The miner owns 75% of the EPKs, the field expert owns 9% of the EPKs, and the voting user shares 1% of the EPKs.
The other 15% of the EPK will fluctuate based on the daily traffic to the network, and the 15% is partly a game between the miner and the field expert.
The first describes the relationship between the two roles.
The first group of field experts are selected by the Foundation, who cover different areas of knowledge (a wide range of knowledge here, including not only serious subjects, but also home, food, travel, etc.) This group of field experts can recommend the next group of field experts, and the recommended experts only need to get 100,000 EPK votes to become field experts.
The field expert’s role is to submit high-quality data to the miner, who is responsible for encapsulating this data into blocks.
Network activity is judged by the amount of EPKs pledged by the entire network for daily traffic (1 EPK = 10 MB/day), with a higher percentage indicating higher data demand, which requires the miner to increase bandwidth quality.
If the data demand decreases, this requires field experts to provide higher quality data. This is similar to a library with more visitors needing more seats, i.e., paying the miner to upgrade the bandwidth.
When there are fewer visitors, more money is needed to buy better quality books to attract visitors, i.e., money for bounty hunters and field experts to generate more quality knowledge graph data. The game between miners and field experts is the most important game in the ecosystem, unlike the game between the authorities and big miners in the Filecoin ecosystem.
The game relationship between data producers and data storers and a more rational economic model will inevitably lead to an E2P model that generates stored on-chain data of much higher quality than the P2P model, and the quality of bandwidth for data access will be better than the P2P model, resulting in greater business value and better landing scenarios.
I will then answer the question of whether this means that the EpiK protocol will not be universally accessible to all.
The E2P model only qualifies the quality of the data generated and stored, not the roles in the ecosystem; on the contrary, with the introduction of the DAO model, the variety of roles introduced in the EpiK ecosystem (which includes the roles of ordinary people) is not limited. (Bounty hunters who can be competent in their tasks) gives roles and possibilities for how everyone can participate in the system in a more logical way.
For example, a miner with computing power can provide storage, a person with a certain domain knowledge can apply to become an expert (this includes history, technology, travel, comics, food, etc.), and a person willing to mark and correct data can become a bounty hunter.
The presence of various efficient support tools from the project owner will lower the barriers to entry for various roles, thus allowing different people to do their part in the system and together contribute to the ongoing generation of a high-quality decentralized knowledge graph.
Deep Chain Finance:
Leo, some time ago, EpiK released a white paper and an economy whitepaper, explaining the EpiK concept from the perspective of technology and economy model respectively. What I would like to ask is, what are the shortcomings of the current distributed storage projects, and how will EpiK protocol be improved?
Leo:
Distributed storage can easily be misunderstood as those of Ali’s OceanDB, but in the field of blockchain, we should focus on decentralized storage first.
There is a big problem with the decentralized storage on the market now, which is “why not eat meat porridge”.
How to understand it? Decentralized storage is cheaper than centralized storage because of its technical principle, and if it is, the centralized storage is too rubbish for comparison.
What incentive does the average user have to spend more money on decentralized storage to store data?
Is it safer?
Existence miners can shut down at any time on decentralized storage by no means save a share of security in Ariadne and Amazon each.
More private?
There’s no difference between encrypted presence on decentralized storage and encrypted presence on Amazon.
Faster?
The 10,000 gigabytes of bandwidth in decentralized storage simply doesn’t compare to the fiber in a centralized server room. This is the root problem of the business model, no one is using it, no one is buying it, so what’s the big vision.
The goal of EpiK is to guide all community participants in the co-construction and sharing of field knowledge graph data, which is the best way for robots to understand human knowledge, and the more knowledge graph data there is, the more knowledge a robot has, the more intelligent it is exponentially, i.e., EpiK uses decentralized storage technology. The value of exponentially growing data is captured with linearly growing hardware costs, and that’s where the buy-in for EPK comes in.
Organized data is worth a lot more than organized hard drives, and there is a demand for EPK when robots have the need for intelligence.

Let me ask Leo, how many forked projects does Filecoin have so far, roughly? Do you think there will be more or less waves of fork after the mainnet launches? Have the requirements of the miners at large changed when it comes to participation?
Leo:
We don’t have specific statistics, now that the main network launches, we feel that forking projects will increase, there are so many restricted miners in the market that they need to be organized efficiently.
However, we currently see that most forked projects are simply modifying the parameters of Filecoin’s economy model, which is undesirable, and this level of modification can’t change the status quo of miners making up computing power, and the change to the market is just to make some of the big miners feel more comfortable digging up, which won’t help to promote the decentralized storage ecology to land.
We need more reasonable landing scenarios so that idle mining resources can be turned into effective productivity, pitching a 100x coin instead of committing to one Fomo sentiment after another.
Deep Chain Finance:
How far along is the EpiK Protocol project, Eric? What other big moves are coming in the near future?
Eric:
The development of the EpiK Protocol is divided into 5 major phases.
(a) Phase I testing of the network “Obelisk”.
Phase II Main Network 1.0 “Rosetta”.
Phase III Main Network 2.0 “Hammurabi”.
(a) The Phase IV Enrichment Knowledge Mapping Toolkit.
The fifth stage is to enrich the knowledge graph application ecology.
Currently in the first phase of testing network “Obelisk”, anyone can sign up to participate in the test network pre-mining test to obtain ERC20 EPK tokens, after the mainnet exchange on a one-to-one basis.
We have recently launched ERC20 EPK on Uniswap, you can buy and sell it freely on Uniswap or download our EpiK mobile wallet.
In addition, we will soon launch the EpiK Bounty platform, and welcome all community members to do tasks together to build the EpiK community. At the same time, we are also pushing forward the centralized exchange for token listing.
Users’ Questions
User 1:
Some KOLs said, Filecoin consumed its value in the next few years, so it will plunge, what do you think?
Eric:
First of all, the judgment of the market is to correspond to the cycle, not optimistic about the FIL first judgment to do is not optimistic about the economic model of the project, or not optimistic about the distributed storage track.
First of all, we are very confident in the distributed storage track and will certainly face a process of growth and decline, so as to make a choice for a better project.
Since the existing group of miners and the computing power already produced is fixed, and since EpiK miners and FIL miners are compatible, anytime miners will also make a choice for more promising and economically viable projects.
Filecoin consumes the value of the next few years this time, so it will plunge.
Regarding the market issues, the plunge is not a prediction, in the industry or to keep learning iteration and value judgment. Because up and down market sentiment is one aspect, there will be more very important factors. For example, the big washout in March this year, so it can only be said that it will slow down the development of the FIL community. But prices are indeed unpredictable.
User2:
Actually, in the end, if there are no applications and no one really uploads data, the market value will drop, so what are the landing applications of EpiK?
Leo: The best and most direct application of EpiK’s knowledge graph is the question and answer system, which can be an intelligent legal advisor, an intelligent medical advisor, an intelligent chef, an intelligent tour guide, an intelligent game strategy, and so on.

How DAO users can truly control their voting rights

How DAO users can truly control their voting rights
https://blockchaintopbuzz.medium.com/how-dao-users-can-truly-control-their-voting-rights-f945c9c6b65e
Aelf proposed a solution that gives the control of the voting rights back to users by classifying token permissions.
As of today, there are still few complete businesses. In addition to mining and building trading platforms, it is difficult to create a complete business model. Moreover, various trading platforms have gradually grown into enterprises with comprehensive products in the blockchain industry, including wallets, nodes, lending, mining pools, etc.
At the same time, cloud services can reduce the cost of building small exchanges, but they can also lead to big trading platforms monopolizing data. For example, some Internet companies provide free cloud services in order to collect more valuable data.
Currently, Ethereum, which has the richest DeFi ecosystem, is gradually upgrading to V2.0, and its consensus protocol will also be upgraded to PoS. Governance voting can be regarded as the most important feature in the PoS ecosystem.
This year, Yearn.Finance rose to sudden prominence. But due to the governance problem, its community members initiated a hard fork, resulting in YFII. Another DeFi project, YAM, had a unfixable rebase function error. The founding team apologized for the error and announced a ‘Migration Plan’, which will turn the project over to the community.
For a while, governance voting became all the rage. However, the increasingly bigger trading platforms have been criticized by users in governance voting. Is there a proper solution to handling the relationship between the trading platform and governance voting?

What will we lose when trading platforms monopolize the blockchain industry?

In June 2018, during the BP node election before the EOS mainnet launch, node voting began to have a crisis of confidence between token holders and the trading platform. it is widely believed that the top 20 holders of trading platform wallets held about 40% of all the EOS in circulation.
Since then, many trading platforms have enabled the “User Authorization” interface. EOS holders can authorize the token voting rights to the trading platform, who will vote on behalf of the users. The rule caused a backlash from users, forcing these trading platforms to change the rule immediately so that EOS holders could vote on their preferred BP nodes.
After the EOS BP node votes, whether the trading platform has the token voting right has been occasionally discussed, but fewhave noticed it.
Two years later, Justin Sun, founder of TRON, made a commercial acquisition of Steemit, a decentralized social networking platform. After the acquisition was announced, the Steemit community launched a soft fork to resist the project being controlled by TRON. However, Justin Sun voted with the support of trading platforms such as Binance, Huobi and Poloniex to prevent a soft fork.
After being questioned by users, Binance and Huobi said that they would no longer interfere in the voting of the Steemit community. However, hkdev 404 of the Steem community again reveived votes from Huobi accounts. It is said that nearly 40 million votes were cast during the incident, accounting for about 10% of the total circulation of STEEM tokens.
There is no doubt that when the trading platform monopolizes the industry, we will lose our voting right.
How do we defend our voting rights
The fact that the ownership of the tokens belongs to the holders is indisputable, but what about the voting rights of the tokens deposited on the trading platform? How can we defend our voting rights after trading platforms have monopolized the industry?

Trading Platform Model

Traditional centralized trading platforms will assign to each user a separate deposit address. After depositing, the depositedamount will be added into the cold wallet and hot wallet. When users want to withdraw their tokens, the trading platform will transfer the tokens out of the hot wallet. If there is insufficient balance in the hot wallet, then the tokens will be transferred from the cold wallet to the hot wallet, and then be withdrawn.
Under the traditional centralized trading platform model, once users transfer their tokens into a trading platform, it means thetoken ownership (including voting rights) is also transferred to that trading platform.
The aelf solution: classify token permissions and claim back voting rights
For the issue of “voting rights” between token holders and centralized trading platforms, aelf, a decentralized cloud computing blockchain network, has proposed a solution: to establish an aelf Centre Asset Management Contract on the chain. The contract can limit the funds entering the exchange and define different permissions to control the assets.
The main feature of the aelf Centre Asset Management Contract is to create the “Main Virtual Address of the Trading Platform”.
Each exchange has a main virtual address, which can only be used for transfer operation, but not for voting, trading and other operations. As a result, the exchange cannot misappropriate users’ assets for voting. At the same time, the assets of the primary virtual address are publicly available on the chain, which makes it more difficult for the exchange to misappropriate assets.
At the same time, the aelf Centre Asset Management Contract also has the function of “address definition”. The exchange can open different permissions to different addresses, such as opening different permissions according to the amount, transactions exceeding a certain amount can only be given the greenlight by using multiple signatures, and the assets can be frozen through the contract when the assets of the trading platform are stolen, etc.
For the users of the trading platform, the access of the trading platform to the aelf Center Asset Management Contract function will not undermine user experience. The virtual system address of the aelf Center Asset Management Contract will assign a virtual address to each user, which offers the same user experience as the traditional mode.
For the trading platform, each deposit address constructed by the virtual address system is generated by the algorithm and does not need to be carried out on the blockchain. This means that the trading platform does not need to manage a large number of private keys, and there is no risk that the private keys will be lost.
On the most important “voting rights” issue, the aelf Center Asset Management Contract will assign to each user a separate virtual address for voting:
Voting address = Hash (Exchange Main Address + Token + “VOTE”)
Voting process: the tokens are transferred from the main virtual address of the exchange to the special “voting address” for voting, and are then voted. After voting, the tokens are withdrawn from the voting address back to the main virtual address.
We can see that the aelf Centre Asset Management Contract proposed by aelf can improve the efficiency of the trading platform without affecting user experience. In addition, it solves the problem that users would lose their voting rights.
According to the data on Crypto Mode, the market value of PoS tokens has exceeded $33 billion without counting Ethereum. In the field of crypto, it is the biggest ecosystem next to Bitcoin. The most important function of PoS is vote staking. faced with bigtrading platforms, if the status quo continues, retail investors will gradually lose their “voting rights” that belong to them.

Comparison of Market Value of PoS tokens (Source: Crypto Mode)
The emergence of DAO offers an alternative to trading platforms who misappropriate users’ tokens, but it still can not change this situation. Of course, DAO will not die out. Small communities will still use DAO for community governance. The idea behind the design of aelf is to start from the underlying trading platform and solve this issue at the source. Whether the solution can work still takes time. However, as a member of the crypto industry, we should understand the importance of “voting rights”, and cannot allow the exchange to seize our rights at will.
Recently, aelf has also announced its DeFi plan, which includes a new blockchain 3.0 project with a large number of new technical features, such as cross chain function, virtual address and cloud services. Aelf also proposed a set of interoperability solutions with ERC-20 tokens. It can directly access the ETH ecosystem, allow ETH-based applications and wallets to directly access it, and maintain the interoperability with ETH. And aelf will provide a high-performance smart contract operation platform and cloud services that can support cross chain interaction. Users on major cloud servers can easily run aelf’s services and adjust the scale of cloud according to their own business needs.
The implementation of a slew of tools, cloud services and interoperability solutions developed by aelf means that centralized transactions can be directly connected to the aelf network, realizing one-click adaptation to the DeFi ecosystem. With aelf, CeFi and DeFi are able to learn from and complement each other.

MMSS - Massive Multi Signature Scheme

On the latest Noded podcast with the Bitcoin Rabbi, the Bitcoin Rabbi talked about how he made, for experimental reasons, a 15-of-15-MultiSig-wallet with 14 of his friends.
This got me thinking about secure long term storage of funds.
Multi-Sig is the way to go. And usually I'd say something like a 3-of-5 or 2-of-3 setup, where all keys are on permanently offline media (paper, hardware wallet, permanently offline laptop,...).
But how much less secure would something like this be in comparison?
Alice's 6-of-10 setup between her, Bob and Charlie.
The advantage is, that this would be pretty easy to setup. They all have their laptop ready, a shared Dropbox folder to put the master-public-keys in. They could perform tests every 3 months or so, signing a message with all devices, and that wouldn't be too much work, because everything except the banksafe wallet is easily accessed.
Bob and Charlie can do the same thing in the same group, they would simply have their own banksafe with a different wallet in there.
Why is this stupid?

Common sites with HIGHEST payout and STABLE income << 04/10/2020 >>

This is a long post, but please try to read it all and select the most suitable one for you. When you see any sites with good payout and good potential, feel free to create a post. Also when you know site that is scam, please create a post to alert everyone as soon as possible.

There're 4 main and common types of task you will encounter when using beermoney sites. You can use all the sites or just pick the most suitable type and site to work with. Using more than one site is recommended, as the number of tasks on one site is not high enough, and the tasks will not appear continuously.

I. MICRO-TASK (or Crowdsourcing task)

The task is vary from article assessment, information collection, search-query classification/answer relevance, taking or collecting photo/video, to object identification,... The number of tasks will increase as you complete tasks.
Pros:
- The number of tasks is higher and more stable than other type of beermoney.
- The payout is appropriate to your time and effort. You can even make stable income with them.
Cons:
- Sometime you will need to pass the training test to access the task.
- Your work may not be accepted if it does not meet the guideline.
- It can be a little hard in the beginning, there're also not many tasks for you, but BE PATIENT, because they haven't been able to fully assess your ability yet.
1-Toloka Yandex:
This is one of my favorite micro task sites, and is the first on the list when I make beermoney site suggestion.
The tasks are mainly in English and Russian. They also have task in your mother language too, depend on your setting and location. Don't worry about the language, as you can easily have it to be translated with google translate extension or any translation site and the task is easy enough to understand.
The minimum withdrawal is $0.02 if you request to withdrawal once a week, and it will be $1 if more than once a week. You can withdraw the money to PayPal, Payoneer, Skrill or papara. But to be able to withdraw with PayPal, you will need a verified PayPal account.
Here are registration links: ref-link and no-ref
2-Clickworker:
One of the most popular micro task sites, you can find many recommendations and good reputation about them. But to make the most if it, you will need to unlock UHRS, as describe here.
You definitely shouldn't miss Clickworker and UHRS. Their payout rate is higher than Toloka, but be careful that you'll be considered as spam if you complete the task too fast. Depend on your location and language, you can earn a great amount of money here, the highest I've earned in 1 day is $35.
You can receive payment to PayPal account with the minimum of €5. You can choose other payment methods too, like SEPA transfers and Transferwise.
No need to say anymore, here are the links: ref-link and no-ref
3-Remotasks
You will need to take part in training (which is quite hard and time-consuming) and pass the test to be able to access a large number of tasks here. The tasks are categorization, text highlighting, image annotation, semantic segmentation,... and well-known Lidar Annotation and Segmentation.
Here are registration links: ref-link and no-ref

NOTE FOR MICRO-TASK:
  1. It's highly recommended to use all those sites, and maybe other sites if you want, because the tasks are not shown continuously.
  2. Make sure to fully understand the guideline, as you will not be credited if you work fails to meet the requirement, which will waste your time and effort.
  3. If you find any task with really low credit but require a lot of time and effort, don't do it. If the requester still be able to find worker, they will always offer that price. It's not worth your time, just going to other tasks or going to other sites to see if there're any available tasks for you.

II. OFFER WALL TASK

Another way to earn beermoney online is to complete Offer wall tasks. You will be asked to installing app on your smartphone, signing up, playing game and reaching determined level, or watching video,.... Doing survey can also be listed here, but it will be shown in separate section.
There're many offer walls for you to choose, with different payout level. Usually each beermoney site will list many offer walls, one offer can appear in more than one site/wall, so make sure to surf around and compare the credit to find the best and highest payout wall/site for that offer.
Pros:
- Easy to do
- Can complete offer many times if you have different kinds of phone (mostly Android and iOS), or using another phone as the tasks are listed on many different offer walls.
- Can earn money while playing and relaxing, as mostly the offered apps are games. Some apps only requires you to install and open, make it really quick to have some beermoney.
Cons:
- The payout is not very high. Especially when that offer is going through many walls and sites to reach you.
- Some offer take much time to complete.
- The number of offers is not high enough to do daily.
1-RewardXP
RewardXP has surpassed GG2U to become the highest payout site. They have leveling system, the higher level you reach, the more offer walls you can access and the more benefit you can get.
With the minimum of $5, they provide a variety of withdrawal methods for you to choose, like PayPal, Amazon, Steam,...
You definitely should try this site. Here are your registration links: ref-link and no-ref. Registration with referral link, you will be given a 5000XP (~$0.5) bonus.
2-GG2U:
This is also my favorite site. Their paying rate is one of the highest in the market (if you find any other site which is higher, feel free to suggest :D THE HIGHEST ONE NOW is RewardXP, see above). Aside from installing and registering app, they also have many survey walls for you.
The most attractive part is that they will give you $1 bonus right after signing up, and after 5 withdrawal requests, you will have a chance to earn up to $7 bonus. With bonus, it's hard to say which is better, RewardXP or GG2U.
You can withdraw money to your PayPal account or Coinbase (crypto wallet), with the minimum of $7.
Here are your links: ref-link and no-ref
3-Cointiply
One of the most popular sites, with great community.
They will pay you with cryptocurrency like Bitcoin or Doge. You will have many chances to earn coins, by doing offer walls task, rolling the faucet every 1 hour, testing your luck with multiplier or by activating in their really crowded chat room.
You can also earn some coins by clicking Paid-to-click ads. Most of the time, those ads are from Cointiply user with their referral link embedded, so if you register sites when viewing those ads, they will earn some commission. You can try this strategy too :D
With their mobile app, it will be much easier to do mobile offers. Make sure to check your email and mobile app to get the user-limited Promotion Codes regularly.
Registration links: ref-link and no-ref
4-Swagbucks
Sometime you can earn money by spending less. Swagbucks offers a big number of sites where you can receive cash back when you shop online. If you shop online a lot, it's worth to take a look
Here are registration link for shopping: ref-link-shopping and no-ref-shopping
Beside the cash back program, Swagbucks also provides offer wall, however the paying rate is not as high as site 1 and 2 above. Anyway, if you want to try, here're your registration links: ref-link and no-ref
5-EarnCrypto
If you're into doing offer walls task and earning crypto currency, try this site too.
Their paying rate is quite lower than above sites, but they have Data entry task, which is daily, for you to earn some coins. By ranking high on their daily leader board, you will be rewarded with a great amount of coins (can even be higher than your earning from doing the data entry task itself :D).
There are many different kinds of crypto currency for you to select.
Just take a look if you have time: ref-link and no-ref
NOTE FOR OFFER WALL TASK:
  1. Every offer wall has a place to track your activity history, like what offer you clicked, what offer you completed and did you receive credit or not. Every time you're about to do an offer, after entering that offer (usually when you click an offer, a small panel about what offer is appears, there will be a button name 'continue' or 'go to offer', after you click that button, you're entering the offer), make sure that offer appears in your history tab of that offer wall. This will enable you to request support in case you complete the offer and have not received credit yet. If it does not appear in the history list, you will not be credited for that offer, so try to click it again.
  2. To find the history tab, after entering offer wall, you will need to find a button named 'My coin', 'My history', 'Support', or button with question mark,... That button should be easy to be found.
  3. Try to surf around to find the offer wall and site having the highest paying rate for the offer, as the same offer will appear in many offer walls and sites.
  4. When you're about to start to do an offer of installing app (especially game), try to read the comment in appstore/playstore to see whether the offer's requirements can be easily to fulfill or not. For example, the requirements are: 1. install game, 2. open it, 3. reach level 30; and you find some comment about cannot reach level 25, or it takes months to reach level 29, then skip that offer, it's not worth the try.

III. PAY TO SEARCH

You can earn nearly passive income from this type of task. They will give you some query, you will search with that query, entering determined site, leaving that site opened for couple of minutes.
Pros:
- It's super easy to do.
- While leaving the site open, you can do any other thing you want, like doing some micro-tasks.
- The paying rate is quite good, especially when you will not need to do much.
Cons:
- The number of queries is not very high.
1-SerpClix
In order to receive more queries to search, make sure to leave the site open and allow the notification.
Even though SerpClix recommends you to click on the page, don't do that, just using scrollbar. SerpClix will automatically navigate to sub page of that page. Another suggestion here is to install adblock extension, because SerpClix will ban you if you click on any ads on the page, so blocking them before hand is a good move.
Here your registration links: ref-link and no-ref

IV. SURVEY

Probably all offer walls have some kind of surveys there, some surveys are only available through offer walls, some have their own sites. By using their own sites will not guarantee that you will have higher payout though.
Make sure to be honest when doing survey, despite the fact that you will sometime be disqualified from the survey. There's many reasons why you are disqualified, like because your job is not suitable, your demography is not their target, your answer is not persistent,...
BE CAREFUL, they will keep track of you, even if you clear your cookie, so being dishonest can lead you to be banned from their sites. Again, BE HONEST, and there will be suitable surveys for you.
There will be two types of survey for you: the first one is filling form and selecting answer from their suggestion, the second one is to talk with them directly or via Video call apps. The second one has much much higher earning but the requirement is also higher too.
Pros:
- Easy to do, just being honest
- High payout, especially with the second type of survey.
- Some survey only need 5 minutes to complete with good payout.
Cons:
- Some survey can take about 30 minutes to complete, so make sure that you have enough free time.
- You will be disqualified if your information is not suitable to their survey's target. BUT ALWAYS BE HONEST.
1-SurveyTime
One of the best sites out there, my favorite one. They will instantly send you $1 or $0.5 (depend on survey) to your PayPal or Coinbase account when you complete the survey, so no minimum required to withdrawal. The survey you will do here is the first type, filling in the form and selecting answer.
You can register with SurveyTime through some offer walls, as they will give you some more coins when you complete the survey, but make sure to check their's conditions.
Make sure to turn on Browser notification and Email notification so that you don't miss any survey.
Registration links: no-ref
2-Respondent
You will need a microphone and/or webcam (built-in or external) as the survey in Respondent is conducted via video calls, phone calls, in-person discussions. Of course, you will receive a huge credit for doing survey here, from $5 up-to $1000. This's a great deal, one successful survey can get you more credit than doing hundreds of micro-tasks. Don't miss this site.
They will recommend suitable survey for you, but if you want to view all available survey, make sure to uncheck the 'Recommended' option in Filter panel.
Here're your registration links: ref-link and no-ref
NOTE FOR SURVEY TASK:
  1. sometime, they will provide the must-select answer in the question to test if your attention. Make sure to read the question carefully. For example, the question is "Do you agree that 1 + 1 = 2? Select option [I do not agree] in the answer", if you select [I agree], you fail.
  2. BE CAREFUL - BE HONEST
  3. When you're doing the first type survey (filling form, selecting answer), be careful not to install any app, or download any thing, or upload your social data file when asked. In that case, just contact survey site support and report it.
  4. It's better to use many different survey sites to maximum the number of surveys you receive.

Last word, BE PATIENT - earning online can be a little hard in the beginning.

Feel free to share your experience when using beermoney sites (and your referral link too :D) or ask question about any beermoney sites by creating new post. Also creating new post when you know that any site is scam or becomes scam.

P.S 1: In case you need a Crypto wallet, you can use Coinbase, registration links: ref-link and no-ref, or Binance ref-link and no-ref. You can read here for the comparison between Coibase and Binance
P.S 2: You can add some email addresses to PayPal account, so you can use many email address to register to beermoney sites if you want
P.S 3: If you're confident with your English, and have a computer, microphone and webcam, you can try Usertesting site, you will visit a website that requires you to test, talk about your experience of using that site

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

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake
https://preview.redd.it/b80c05tnb9e51.jpg?width=2550&format=pjpg&auto=webp&s=850282c1a3962466ed44f73886dae1c8872d0f31
Submitted for consideration 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.
