Proposal: The Sia Foundation

Vision Statement

A common sentiment is brewing online; a shared desire for the internet that might have been. After decades of corporate encroachment, you don't need to be a power user to realize that something has gone very wrong.
In the early days of the internet, the future was bright. In that future, when you sent an instant message, it traveled directly to the recipient. When you needed to pay a friend, you announced a transfer of value to their public key. When an app was missing a feature you wanted, you opened up the source code and implemented it. When you took a picture on your phone, it was immediately encrypted and backed up to storage that you controlled. In that future, people would laugh at the idea of having to authenticate themselves to some corporation before doing these things.
What did we get instead? Rather than a network of human-sized communities, we have a handful of enormous commons, each controlled by a faceless corporate entity. Hey user, want to send a message? You can, but we'll store a copy of it indefinitely, unencrypted, for our preference-learning algorithms to pore over; how else could we slap targeted ads on every piece of content you see? Want to pay a friend? You can—in our Monopoly money. Want a new feature? Submit a request to our Support Center and we'll totally maybe think about it. Want to backup a photo? You can—inside our walled garden, which only we (and the NSA, of course) can access. Just be careful what you share, because merely locking you out of your account and deleting all your data is far from the worst thing we could do.
You rationalize this: "MEGACORP would never do such a thing; it would be bad for business." But we all know, at some level, that this state of affairs, this inversion of power, is not merely "unfortunate" or "suboptimal" – No. It is degrading. Even if MEGACORP were purely benevolent, it is degrading that we must ask its permission to talk to our friends; that we must rely on it to safeguard our treasured memories; that our digital lives are completely beholden to those who seek only to extract value from us.
At the root of this issue is the centralization of data. MEGACORP can surveil you—because your emails and video chats flow through their servers. And MEGACORP can control you—because they hold your data hostage. But centralization is a solution to a technical problem: How can we make the user's data accessible from anywhere in the world, on any device? For a long time, no alternative solution to this problem was forthcoming.
Today, thanks to a confluence of established techniques and recent innovations, we have solved the accessibility problem without resorting to centralization. Hashing, encryption, and erasure encoding got us most of the way, but one barrier remained: incentives. How do you incentivize an anonymous stranger to store your data? Earlier protocols like BitTorrent worked around this limitation by relying on altruism, tit-for-tat requirements, or "points" – in other words, nothing you could pay your electric bill with. Finally, in 2009, a solution appeared: Bitcoin. Not long after, Sia was born.
Cryptography has unleashed the latent power of the internet by enabling interactions between mutually-distrustful parties. Sia harnesses this power to turn the cloud storage market into a proper marketplace, where buyers and sellers can transact directly, with no intermediaries, anywhere in the world. No more silos or walled gardens: your data is encrypted, so it can't be spied on, and it's stored on many servers, so no single entity can hold it hostage. Thanks to projects like Sia, the internet is being re-decentralized.
Sia began its life as a startup, which means it has always been subjected to two competing forces: the ideals of its founders, and the profit motive inherent to all businesses. Its founders have taken great pains to never compromise on the former, but this often threatened the company's financial viability. With the establishment of the Sia Foundation, this tension is resolved. The Foundation, freed of the obligation to generate profit, is a pure embodiment of the ideals from which Sia originally sprung.
The goals and responsibilities of the Foundation are numerous: to maintain core Sia protocols and consensus code; to support developers building on top of Sia and its protocols; to promote Sia and facilitate partnerships in other spheres and communities; to ensure that users can easily acquire and safely store siacoins; to develop network scalability solutions; to implement hardforks and lead the community through them; and much more. In a broader sense, its mission is to commoditize data storage, making it cheap, ubiquitous, and accessible to all, without compromising privacy or performance.
Sia is a perfect example of how we can achieve better living through cryptography. We now begin a new chapter in Sia's history. May our stewardship lead it into a bright future.
 

Overview

Today, we are proposing the creation of the Sia Foundation: a new non-profit entity that builds and supports distributed cloud storage infrastructure, with a specific focus on the Sia storage platform. What follows is an informal overview of the Sia Foundation, covering two major topics: how the Foundation will be funded, and what its funds will be used for.

Organizational Structure

The Sia Foundation will be structured as a non-profit entity incorporated in the United States, likely a 501(c)(3) organization or similar. The actions of the Foundation will be constrained by its charter, which formalizes the specific obligations and overall mission outlined in this document. The charter will be updated on an annual basis to reflect the current goals of the Sia community.
The organization will be operated by a board of directors, initially comprising Luke Champine as President and Eddie Wang as Chairman. Luke Champine will be leaving his position at Nebulous to work at the Foundation full-time, and will seek to divest his shares of Nebulous stock along with other potential conflicts of interest. Neither Luke nor Eddie personally own any siafunds or significant quantities of siacoin.

Funding

The primary source of funding for the Foundation will come from a new block subsidy. Following a hardfork, 30 KS per block will be allocated to the "Foundation Fund," continuing in perpetuity. The existing 30 KS per block miner reward is not affected. Additionally, one year's worth of block subsidies (approximately 1.57 GS) will be allocated to the Fund immediately upon activation of the hardfork.
As detailed below, the Foundation will provably burn any coins that it cannot meaningfully spend. As such, the 30 KS subsidy should be viewed as a maximum. This allows the Foundation to grow alongside Sia without requiring additional hardforks.
The Foundation will not be funded to any degree by the possession or sale of siafunds. Siafunds were originally introduced as a means of incentivizing growth, and we still believe in their effectiveness: a siafund holder wants to increase the amount of storage on Sia as much as possible. While the Foundation obviously wants Sia to succeed, its driving force should be its charter. Deriving significant revenue from siafunds would jeopardize the Foundation's impartiality and focus. Ultimately, we want the Foundation to act in the best interests of Sia, not in growing its own budget.

Responsibilities

The Foundation inherits a great number of responsibilities from Nebulous. Each quarter, the Foundation will publish the progress it has made over the past quarter, and list the responsibilities it intends to prioritize over the coming quarter. This will be accompanied by a financial report, detailing each area of expenditure over the past quarter, and forecasting expenditures for the coming quarter. Below, we summarize some of the myriad responsibilities towards which the Foundation is expected to allocate its resources.

Maintain and enhance core Sia software

Arguably, this is the most important responsibility of the Foundation. At the heart of Sia is its consensus algorithm: regardless of other differences, all Sia software must agree upon the content and rules of the blockchain. It is therefore crucial that the algorithm be stewarded by an entity that is accountable to the community, transparent in its decision-making, and has no profit motive or other conflicts of interest.
Accordingly, Sia’s consensus functionality will no longer be directly maintained by Nebulous. Instead, the Foundation will release and maintain an implementation of a "minimal Sia full node," comprising the Sia consensus algorithm and P2P networking code. The source code will be available in a public repository, and signed binaries will be published for each release.
Other parties may use this code to provide alternative full node software. For example, Nebulous may extend the minimal full node with wallet, renter, and host functionality. The source code of any such implementation may be submitted to the Foundation for review. If the code passes review, the Foundation will provide "endorsement signatures" for the commit hash used and for binaries compiled internally by the Foundation. Specifically, these signatures assert that the Foundation believes the software contains no consensus-breaking changes or other modifications to imported Foundation code. Endorsement signatures and Foundation-compiled binaries may be displayed and distributed by the receiving party, along with an appropriate disclaimer.
A minimal full node is not terribly useful on its own; the wallet, renter, host, and other extensions are what make Sia a proper developer platform. Currently, the only implementations of these extensions are maintained by Nebulous. The Foundation will contract Nebulous to ensure that these extensions continue to receive updates and enhancements. Later on, the Foundation intends to develop its own implementations of these extensions and others. As with the minimal node software, these extensions will be open source and available in public repositories for use by any Sia node software.
With the consensus code now managed by the Foundation, the task of implementing and orchestrating hardforks becomes its responsibility as well. When the Foundation determines that a hardfork is necessary (whether through internal discussion or via community petition), a formal proposal will be drafted and submitted for public review, during which arguments for and against the proposal may be submitted to a public repository. During this time, the hardfork code will be implemented, either by Foundation employees or by external contributors working closely with the Foundation. Once the implementation is finished, final arguments will be heard. The Foundation board will then vote whether to accept or reject the proposal, and announce their decision along with appropriate justification. Assuming the proposal was accepted, the Foundation will announce the block height at which the hardfork will activate, and will subsequently release source code and signed binaries that incorporate the hardfork code.
Regardless of the Foundation's decision, it is the community that ultimately determines whether a fork is accepted or rejected – nothing can change that. Foundation node software will never automatically update, so all forks must be explicitly adopted by users. Furthermore, the Foundation will provide replay and wipeout protection for its hard forks, protecting other chains from unintended or malicious reorgs. Similarly, the Foundation will ensure that any file contracts formed prior to a fork activation will continue to be honored on both chains until they expire.
Finally, the Foundation also intends to pursue scalability solutions for the Sia blockchain. In particular, work has already begun on an implementation of Utreexo, which will greatly reduce the space requirements of fully-validating nodes (allowing a full node to be run on a smartphone) while increasing throughput and decreasing initial sync time. A hardfork implementing Utreexo will be submitted to the community as per the process detailed above.
As this is the most important responsibility of the Foundation, it will receive a significant portion of the Foundation’s budget, primarily in the form of developer salaries and contracting agreements.

Support community services

We intend to allocate 25% of the Foundation Fund towards the community. This allocation will be held and disbursed in the form of siacoins, and will pay for grants, bounties, hackathons, and other community-driven endeavours.
Any community-run service, such as a Skynet portal, explorer or web wallet, may apply to have its costs covered by the Foundation. Upon approval, the Foundation will reimburse expenses incurred by the service, subject to the exact terms agreed to. The intent of these grants is not to provide a source of income, but rather to make such services "break even" for their operators, so that members of the community can enrich the Sia ecosystem without worrying about the impact on their own finances.

Ensure easy acquisition and storage of siacoins

Most users will acquire their siacoins via an exchange. The Foundation will provide support to Sia-compatible exchanges, and pursue relevant integrations at its discretion, such as Coinbase's new Rosetta standard. The Foundation may also release DEX software that enables trading cryptocurrencies without the need for a third party. (The Foundation itself will never operate as a money transmitter.)
Increasingly, users are storing their cryptocurrency on hardware wallets. The Foundation will maintain the existing Ledger Nano S integration, and pursue further integrations at its discretion.
Of course, all hardware wallets must be paired with software running on a computer or smartphone, so the Foundation will also develop and/or maintain client-side wallet software, including both full-node wallets and "lite" wallets. Community-operated wallet services, i.e. web wallets, may be funded via grants.
Like core software maintenance, this responsibility will be funded in the form of developer salaries and contracting agreements.

Protect the ecosystem

When it comes to cryptocurrency security, patching software vulnerabilities is table stakes; there are significant legal and social threats that we must be mindful of as well. As such, the Foundation will earmark a portion of its fund to defend the community from legal action. The Foundation will also safeguard the network from 51% attacks and other threats to network security by implementing softforks and/or hardforks where necessary.
The Foundation also intends to assist in the development of a new FOSS software license, and to solicit legal memos on various Sia-related matters, such as hosting in the United States and the EU.
In a broader sense, the establishment of the Foundation makes the ecosystem more robust by transferring core development to a more neutral entity. Thanks to its funding structure, the Foundation will be immune to various forms of pressure that for-profit companies are susceptible to.

Drive adoption of Sia

Although the overriding goal of the Foundation is to make Sia the best platform it can be, all that work will be in vain if no one uses the platform. There are a number of ways the Foundation can promote Sia and get it into the hands of potential users and developers.
In-person conferences are understandably far less popular now, but the Foundation can sponsor and/or participate in virtual conferences. (In-person conferences may be held in the future, permitting circumstances.) Similarly, the Foundation will provide prizes for hackathons, which may be organized by community members, Nebulous, or the Foundation itself. Lastly, partnerships with other companies in the cryptocurrency space—or the cloud storage space—are a great way to increase awareness of Sia. To handle these responsibilities, one of the early priorities of the Foundation will be to hire a marketing director.

Fund Management

The Foundation Fund will be controlled by a multisig address. Each member of the Foundation's board will control one of the signing keys, with the signature threshold to be determined once the final composition of the board is known. (This threshold may also be increased or decreased if the number of board members changes.) Additionally, one timelocked signing key will be controlled by David Vorick. This key will act as a “dead man’s switch,” to be used in the event of an emergency that prevents Foundation board members from reaching the signature threshold. The timelock ensures that this key cannot be used unless the Foundation fails to sign a transaction for several months.
On the 1st of each month, the Foundation will use its keys to transfer all siacoins in the Fund to two new addresses. The first address will be controlled by a high-security hot wallet, and will receive approximately one month's worth of Foundation expenditures. The second address, receiving the remaining siacoins, will be a modified version of the source address: specifically, it will increase the timelock on David Vorick's signing key by one month. Any other changes to the set of signing keys, such as the arrival or departure of board members, will be incorporated into this address as well.
The Foundation Fund is allocated in SC, but many of the Foundation's expenditures must be paid in USD or other fiat currency. Accordingly, the Foundation will convert, at its discretion, a portion of its monthly withdrawals to fiat currency. We expect this conversion to be primarily facilitated by private "OTC" sales to accredited investors. The Foundation currently has no plans to speculate in cryptocurrency or other assets.
Finally, it is important that the Foundation adds value to the Sia platform well in excess of the inflation introduced by the block subsidy. For this reason, the Foundation intends to provably burn, on a quarterly basis, any coins that it cannot allocate towards any justifiable expense. In other words, coins will be burned whenever doing so provides greater value to the platform than any other use. Furthermore, the Foundation will cap its SC treasury at 5% of the total supply, and will cap its USD treasury at 4 years’ worth of predicted expenses.
 
Addendum: Hardfork Timeline
We would like to see this proposal finalized and accepted by the community no later than September 30th. A new version of siad, implementing the hardfork, will be released no later than October 15th. The hardfork will activate at block 293220, which is expected to occur around 12pm EST on January 1st, 2021.
 
Addendum: Inflation specifics
The total supply of siacoins as of January 1st, 2021 will be approximately 45.243 GS. The initial subsidy of 1.57 GS thus increases the supply by 3.47%, and the total annual inflation in 2021 will be at most 10.4% (if zero coins are burned). In 2022, total annual inflation will be at most 6.28%, and will steadily decrease in subsequent years.
 

Conclusion

We see the establishment of the Foundation as an important step in the maturation of the Sia project. It provides the ecosystem with a sustainable source of funding that can be exclusively directed towards achieving Sia's ambitious goals. Compared to other projects with far deeper pockets, Sia has always punched above its weight; once we're on equal footing, there's no telling what we'll be able to achieve.
Nevertheless, we do not propose this change lightly, and have taken pains to ensure that the Foundation will act in accordance with the ideals that this community shares. It will operate transparently, keep inflation to a minimum, and respect the user's fundamental role in decentralized systems. We hope that everyone in the community will consider this proposal carefully, and look forward to a productive discussion.

Why Osana takes so long? (Programmer's point of view on current situation)

I decided to write a comment about «Why Osana takes so long?» somewhere and what can be done to shorten this time. It turned into a long essay. Here's TL;DR of it:
The cost of never paying down this technical debt is clear; eventually the cost to deliver functionality will become so slow that it is easy for a well-designed competitive software product to overtake the badly-designed software in terms of features. In my experience, badly designed software can also lead to a more stressed engineering workforce, in turn leading higher staff churn (which in turn affects costs and productivity when delivering features). Additionally, due to the complexity in a given codebase, the ability to accurately estimate work will also disappear.
Junade Ali, Mastering PHP Design Patterns (2016)
Longer version: I am not sure if people here wanted an explanation from a real developer who works with C and with relatively large projects, but I am going to do it nonetheless. I am not much interested in Yandere Simulator nor in this genre in general, but this particular development has a lot to learn from for any fellow programmers and software engineers to ensure that they'll never end up in Alex's situation, especially considering that he is definitely not the first one to got himself knee-deep in the development hell (do you remember Star Citizen?) and he is definitely not the last one.
On the one hand, people see that Alex works incredibly slowly, equivalent of, like, one hour per day, comparing it with, say, Papers, Please, the game that was developed in nine months from start to finish by one guy. On the other hand, Alex himself most likely thinks that he works until complete exhaustion each day. In fact, I highly suspect that both those sentences are correct! Because of the mistakes made during early development stages, which are highly unlikely to be fixed due to the pressure put on the developer right now and due to his overall approach to coding, cost to add any relatively large feature (e.g. Osana) can be pretty much comparable to the cost of creating a fan game from start to finish. Trust me, I've seen his leaked source code (don't tell anybody about that) and I know what I am talking about. The largest problem in Yandere Simulator right now is its super slow development. So, without further ado, let's talk about how «implementing the low hanging fruit» crippled the development and, more importantly, what would have been an ideal course of action from my point of view to get out. I'll try to explain things in the easiest terms possible.
  1. else if's and lack any sort of refactoring in general
The most «memey» one. I won't talk about the performance though (switch statement is not better in terms of performance, it is a myth. If compiler detects some code that can be turned into a jump table, for example, it will do it, no matter if it is a chain of if's or a switch statement. Compilers nowadays are way smarter than one might think). Just take a look here. I know that it's his older JavaScript code, but, believe it or not, this piece is still present in C# version relatively untouched.
I refactored this code for you using C language (mixed with C++ since there's no this pointer in pure C). Take a note that else if's are still there, else if's are not the problem by itself.
The refactored code is just objectively better for one simple reason: it is shorter, while not being obscure, and now it should be able to handle, say, Trespassing and Blood case without any input from the developer due to the usage of flags. Basically, the shorter your code, the more you can see on screen without spreading your attention too much. As a rule of thumb, the less lines there are, the easier it is for you to work with the code. Just don't overkill that, unless you are going to participate in International Obfuscated C Code Contest. Let me reiterate:
Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.
Antoine de Saint-Exupéry
This is why refactoring — activity of rewriting your old code so it does the same thing, but does it quicker, in a more generic way, in less lines or simpler — is so powerful. In my experience, you can only keep one module/class/whatever in your brain if it does not exceed ~1000 lines, maybe ~1500. Splitting 17000-line-long class into smaller classes probably won't improve performance at all, but it will make working with parts of this class way easier.
Is it too late now to start refactoring? Of course NO: better late than never.
  1. Comments
If you think that you wrote this code, so you'll always easily remember it, I have some bad news for you: you won't. In my experience, one week and that's it. That's why comments are so crucial. It is not necessary to put a ton of comments everywhere, but just a general idea will help you out in the future. Even if you think that It Just Works™ and you'll never ever need to fix it. Time spent to write and debug one line of code almost always exceeds time to write one comment in large-scale projects. Moreover, the best code is the code that is self-evident. In the example above, what the hell does (float) 6 mean? Why not wrap it around into the constant with a good, self-descriptive name? Again, it won't affect performance, since C# compiler is smart enough to silently remove this constant from the real code and place its value into the method invocation directly. Such constants are here for you.
I rewrote my code above a little bit to illustrate this. With those comments, you don't have to remember your code at all, since its functionality is outlined in two tiny lines of comments above it. Moreover, even a person with zero knowledge in programming will figure out the purpose of this code. It took me less than half a minute to write those comments, but it'll probably save me quite a lot of time of figuring out «what was I thinking back then» one day.
Is it too late now to start adding comments? Again, of course NO. Don't be lazy and redirect all your typing from «debunk» page (which pretty much does the opposite of debunking, but who am I to judge you here?) into some useful comments.
  1. Unit testing
This is often neglected, but consider the following. You wrote some code, you ran your game, you saw a new bug. Was it introduced right now? Is it a problem in your older code which has shown up just because you have never actually used it until now? Where should you search for it? You have no idea, and you have one painful debugging session ahead. Just imagine how easier it would be if you've had some routines which automatically execute after each build and check that environment is still sane and nothing broke on a fundamental level. This is called unit testing, and yes, unit tests won't be able to catch all your bugs, but even getting 20% of bugs identified at the earlier stage is a huge boon to development speed.
Is it too late now to start adding unit tests? Kinda YES and NO at the same time. Unit testing works best if it covers the majority of project's code. On the other side, a journey of a thousand miles begins with a single step. If you decide to start refactoring your code, writing a unit test before refactoring will help you to prove to yourself that you have not broken anything without the need of running the game at all.
  1. Static code analysis
This is basically pretty self-explanatory. You set this thing once, you forget about it. Static code analyzer is another «free estate» to speed up the development process by finding tiny little errors, mostly silly typos (do you think that you are good enough in finding them? Well, good luck catching x << 4; in place of x <<= 4; buried deep in C code by eye!). Again, this is not a silver bullet, it is another tool which will help you out with debugging a little bit along with the debugger, unit tests and other things. You need every little bit of help here.
Is it too late now to hook up static code analyzer? Obviously NO.
  1. Code architecture
Say, you want to build Osana, but then you decided to implement some feature, e.g. Snap Mode. By doing this you have maybe made your game a little bit better, but what you have just essentially done is complicated your life, because now you should also write Osana code for Snap Mode. The way game architecture is done right now, easter eggs code is deeply interleaved with game logic, which leads to code «spaghettifying», which in turn slows down the addition of new features, because one has to consider how this feature would work alongside each and every old feature and easter egg. Even if it is just gazing over one line per easter egg, it adds up to the mess, slowly but surely.
A lot of people mention that developer should have been doing it in object-oritented way. However, there is no silver bullet in programming. It does not matter that much if you are doing it object-oriented way or usual procedural way; you can theoretically write, say, AI routines on functional (e.g. LISP)) or even logical language if you are brave enough (e.g. Prolog). You can even invent your own tiny programming language! The only thing that matters is code quality and avoiding the so-called shotgun surgery situation, which plagues Yandere Simulator from top to bottom right now. Is there a way of adding a new feature without interfering with your older code (e.g. by creating a child class which will encapsulate all the things you need, for example)? Go for it, this feature is basically «free» for you. Otherwise you'd better think twice before doing this, because you are going into the «technical debt» territory, borrowing your time from the future by saying «I'll maybe optimize it later» and «a thousand more lines probably won't slow me down in the future that much, right?». Technical debt will incur interest on its own that you'll have to pay. Basically, the entire situation around Osana right now is just a huge tale about how just «interest» incurred by technical debt can control the entire project, like the tail wiggling the dog.
I won't elaborate here further, since it'll take me an even larger post to fully describe what's wrong about Yandere Simulator's code architecture.
Is it too late to rebuild code architecture? Sadly, YES, although it should be possible to split Student class into descendants by using hooks for individual students. However, code architecture can be improved by a vast margin if you start removing easter eggs and features like Snap Mode that currently bloat Yandere Simulator. I know it is going to be painful, but it is the only way to improve code quality here and now. This will simplify the code, and this will make it easier for you to add the «real» features, like Osana or whatever you'd like to accomplish. If you'll ever want them back, you can track them down in Git history and re-implement them one by one, hopefully without performing the shotgun surgery this time.
  1. Loading times
Again, I won't be talking about the performance, since you can debug your game on 20 FPS as well as on 60 FPS, but this is a very different story. Yandere Simulator is huge. Once you fixed a bug, you want to test it, right? And your workflow right now probably looks like this:
  1. Fix the code (unavoidable time loss)
  2. Rebuild the project (can take a loooong time)
  3. Load your game (can take a loooong time)
  4. Test it (unavoidable time loss, unless another bug has popped up via unit testing, code analyzer etc.)
And you can fix it. For instance, I know that Yandere Simulator makes all the students' photos during loading. Why should that be done there? Why not either move it to project building stage by adding build hook so Unity does that for you during full project rebuild, or, even better, why not disable it completely or replace with «PLACEHOLDER» text for debug builds? Each second spent watching the loading screen will be rightfully interpreted as «son is not coding» by the community.
Is it too late to reduce loading times? Hell NO.
  1. Jenkins
Or any other continuous integration tool. «Rebuild a project» can take a long time too, and what can we do about that? Let me give you an idea. Buy a new PC. Get a 32-core Threadripper, 32 GB of fastest RAM you can afford and a cool motherboard which would support all of that (of course, Ryzen/i5/Celeron/i386/Raspberry Pi is fine too, but the faster, the better). The rest is not necessary, e.g. a barely functional second hand video card burned out by bitcoin mining is fine. You set up another PC in your room. You connect it to your network. You set up ramdisk to speed things up even more. You properly set up Jenkins) on this PC. From now on, Jenkins cares about the rest: tracking your Git repository, (re)building process, large and time-consuming unit tests, invoking static code analyzer, profiling, generating reports and whatever else you can and want to hook up. More importantly, you can fix another bug while Jenkins is rebuilding the project for the previous one et cetera.
In general, continuous integration is a great technology to quickly track down errors that were introduced in previous versions, attempting to avoid those kinds of bug hunting sessions. I am highly unsure if continuous integration is needed for 10000-20000 source lines long projects, but things can be different as soon as we step into the 100k+ territory, and Yandere Simulator by now has approximately 150k+ source lines of code. I think that probably continuous integration might be well worth it for Yandere Simulator.
Is it too late to add continuous integration? NO, albeit it is going to take some time and skills to set up.
  1. Stop caring about the criticism
Stop comparing Alex to Scott Cawton. IMO Alex is very similar to the person known as SgtMarkIV, the developer of Brutal Doom, who is also a notorious edgelord who, for example, also once told somebody to kill himself, just like… However, being a horrible person, SgtMarkIV does his job. He simply does not care much about public opinion. That's the difference.
  1. Go outside
Enough said. Your brain works slower if you only think about games and if you can't provide it with enough oxygen supply. I know that this one is probably the hardest to implement, but…
That's all, folks.
Bonus: Do you think how short this list would have been if someone just simply listened to Mike Zaimont instead of breaking down in tears?

What I currently use for privacy (after almost 2 years of long investing into it)

First of all, my threat model: I'm just an average person that wants to AVOID the maximum I can to be monitored and tracked by the government and big corps, a lot of people out there REALLY hate me and I've gone through lots of harassment and other stuff, I also plan to take my activism and love for freedom more seriously and to do stuff that could potentially lead me to very high danger or even put my life on the line. That being said, my main focus is on something that is privacy-friendly but also something with decent security (no point having a lot of privacy if a script kiddie can just break into it an boom, everything is gone) anonymity is also desirable but I'm pretty aware that true 100% anonymity is simply not possible and to achieve the maximum you can of it currently you'd have to give up A LOT of stuff in which I don't think I really could. So basically, everything that I said + I don't want to give up some hobbies of mine (as playing games etc)
Here's what I use/have done so far, most of it is based on privacytools.io list and research I've done.
Mobile:
Google Pixel 3a XL running GrapheneOS
Apps: Stock apps (Vanadium, Gallery, Clock, Contacts etc) + F-DROID, NewPipe, OsmAnd+, Joplin, Tutanota, K-9 Mail, Aegis Authenticator, KeePassDX, Syncthing, Signal, Librera PRO, Vinyl, Open Camera and Wireguard.
I also use BlahDNS as my private DNS.
Other smartphone stuff/habits: I use a Supershieldz Anti Spy Tempered Glass Screen Protector on my phone and I also have a Faraday Sleeve from Silent Pocket which my phone is on most of the times (I don't have smartphone addiction and would likely advice you to break free from smartphone addiction if you have it). I NEVER use bluetooth (thank god Pixel 3a have a headphone jack so yeah, no bluetooth earphones here) and always keep my Wi-Fi off if I'm not using it.
Computer:
I have a desktop that I built (specs: Asus B450M Gaming, AMD Ryzen 3 3300X, Radeon RX 580 8GB, 16GB DDR4 2666Mhz, 3TB HDD, 480GB SSD) that is dualbooted with QubesOS and Arch Linux.
Qubes is my main OS that I use as daily driver and for my tasks, I use Arch for gaming.
I've installed linux-hardened and its headers packages on my Arch + further kernel hardening using systctl and boot parameters, AppArmor as my MAC system and bubblewrap for sandboxing programs. I also spoof my MAC address and have restricted root access, I've also protected my GRUB with password (and use encrypted boot) and have enabled Microcode updates and have NTP and IPV6 disabled.
Also on Arch, I use iptables as a firewall denying all incoming traffic, and since it's my gaming PC, I don't game on the OS, instead, I use a KVM/QEMU Windows VM for gaming (search "How I Built The "Poor-Shamed" Computer" video to see what I'm talking about) I also use full disk encryption.
Software/Providers:
E-Mails: I use ProtonMail (Plus Account paid with bitcoin) and Tutanota (free account as they don't accept crypto payment yet, come on Tutanota, I've been waiting for it for 2 years already) since I have plus account on ProtonMail it allows me to use ProtonMail Bridge and use it on Claws Mail (desktop) and K-9 Mail (mobile) as for Tutanota I use both desktop and mobile app.
Some other e-mails habits of mine: I use e-mail aliases (ProtonMail plus account provides you with 5) and each alias is used for different tasks (as one for shopping, one for banking, one for accounts etc) and none of my e-mails have my real name on it or something that could be used to identify me. I also highly avoid using stuff that require e-mail/e-mail verification for usage (e-mail is such a pain in the ass tbh) I also make use of Spamgourmet for stuff like temporary e-mail (best service I found for this doing my research, dunno if it's really the best tho, heard that AnonAddy does kinda the same stuff but dunno, recommendations are welcomed)
Browsers/Search Engine: As mentioned, I use Vanadium (Graphene's stock browser) on mobile as it is the recommended browser by Graphene and the one with the best security for Android, for desktop I use a Hardened Firefox (pretty aware of Firefox's security not being that good, but it's the best browser for PC for me as Ungoogled Chromium is still not there in A LOT of things + inherent problems of Chrome as not being able to disable WebRTC unless you use an extension etc) with ghacks-user.js and uBlock Origin (hard mode), uMatrix (globally blocking first party scripts), HTTPS Everywhere (EASE Mode), Decentraleyes (set the recommended rules for both uBlock Origin and uMatrix) and Temporary Containers as addons. I also use Tor Browser (Safest Mode) on a Whonix VM on Qubes sometimes. DuckDuckGo is my to-go search engine and I use DNS over HTTPS on Firefox (BlahDNS as my provider once again)
browsing habits: I avoid JavaScript the maximum I can, if it's really needed, I just allow the scripts temporarely on uBlock Origin/uMatrix and after I'm done I just disable it. I also generally go with old.reddit.com instead of reddit.com (as JavaScript is not required to browse the old client), nitter.net for checking twitter stuff (although I rarely have something peaking my interest on Twitter) and I use invidious.snopyta.org as youtube front-end (I do however use YouTube sometimes if a video I wanna see can't be played on invidious or if I wanna watch a livestream) and html.duckduckgo.com instead of duckduckgo.com other than avoiding JavaScript most of my browsing habits are just common sense at this point I'd say, I also use privatebin (snopyta's instance) instead of pastebin. I also have multiple firefox profiles for different tasks (personal usage, shopping, banking etc)
VPN: I use Mullvad (guess you can mention it here since it's PTIO's recommended) paid with bitcoin and honestly best service available tbh. I use Mullvad's multihop implementation on Wireguard which I manually set myself as I had the time and patience to learn how.
password manager: KeePassXC on desktop and KeePassDX on my smartphone, my password database for my desktop is stored on a USB flash driver I encrypted with VeraCrypt.
some other software on desktop: LibreOffice (as a Microsoft Office substitute), GIMP (Photshop substitute), Vim (I use it for multiple purposes, mainly coding IDE and as a text editor), VLC (media player), Bisq (bitcoin exchange), Wasabi (bitcoin wallet), OBS (screen recording), Syncthing (file sync), qBitTorrent (torrent client) and Element (federated real-time communication software). I sadly couldn't find a good open-source substitute to Sony Vegas (tested many, but none was in the same level of Vegas imo, KDENLive is okay tho) so I just use it on a VM if I need it (Windows VM solely for the purpose of video editing, not the same one I use for gaming)
Other:
router: I have an Asus RT-AC68U with OpenWRT as its firmware. I also set a VPN on it.
cryptocurrency hardware wallet: I store all of my cryptocurrency (Bitcoin and Monero) on a Ledger Nano S, about 97% of my money is on crypto so a hardware wallet is a must for me.
I have lots of USB flash drivers that I use for Live ISOs and for encrypted backups. I also have a USB Data Blocker from PortaPow that I generally use if I need to charge my cellphone in public or in a hotel while on a trip (rare occasion tbh).
I have a Logitech C920e as webcam and a Blue Yeti microphone in which I never let them plugged, I only plug them if it's necessary and after I'm done I just unplug them.
I also have a Nintendo Switch Lite as a gaming console that I most of the times just use offline, I just connect to the internet if needed for a software update and then just turn the Wi-Fi off from it.
Other Habits/Things I've done:
payments: I simply AVOID using credit card, I try to always pay on cash (I live in a third-world country so thank god most of people here still depend on cash only) physically and online I try my best to either by using cryptocurrency or using gift cards/cash by mail if crypto isn't available. I usually buy crypto on Bisq as I just don't trust any KYC exchange (and neither should you) and since there aren't many people here in my area to do face to face bitcoin trade (and I'm skeptical of face to face tbh), I use the Wasabi Wallet (desktop) to coinjoin bitcoin before buying anything as this allows a bit more of privacy, I also coinjoin on Wasabi before sending my bitcoins to my hardware wallet. I also don't have a high consumerism drive so I'm not constantly wanting to buy everything that I see (which helps a lot on this criteria)
social media/accounts: as noted, aside from Signal and Element (which I don't even use that often) I just don't REALLY use any social media (tried Mastodon for a while but I was honestly felt it kinda desert there and most of its userbase from what I've seen were some people I'd just... rather don't hang with tbh) and, althoug not something necessary is something that I really advise people to as social media is literally a poison to your mind.
I also don't own any streaming service like Netflix/Amazon Prime/Spotify etc, I basically pirate series/movies/songs and that's it.
I've also deleted ALL my old accounts from social media (like Twitter etc) and old e-mails. ALL of my important and main accounts have 2FA enabled and are protected by a strong password (I use KeePass to generate a 35 character lenght password with numbers, capital letters, special symbols etc, each account uses a unique password) I also NEVER use my real name on any account and NEVER post any pictures of myself (I rarely take pictures of stuff if anything)
iot/smart devices: aside from my smartphone, I don't have any IOT/smart device as I honestly see no need for them (and most of them are WAY too expensive on third-world countries)
files: I constatly backup all of my files (each two weeks) on encrypted flash drivers, I also use BleachBit for temporary data cleaning and data/file shredding. I also use Syncthing as a substitute to stuff like Google Drive.
Future plans:
learn to self-host and self-host an e-mail/NextCloud (and maybe even a VPN)
find something like BurneHushed but FOSS (if you know any please let me know)
So, how is it? anything that I should do that I'm probably not doing?

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.

Hello Reddit and Ethereum community!

I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.

Executive summary

Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.

Response and PoC

In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.

Live Demo

A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.
24 hours in 4 minutes (YouTube):
24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.
Tooling to reproduce our demo is available here:
https://github.com/dragonchain/spirit-bomb

Source Code

Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.

Scaling

How it works & scales

Architectural Scaling

Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.

Economic Scaling

An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.

Scaled Deployment

Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.

Flexibility in Scaling

Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
  • LBRY - To allow users to deploy content natively to LBRY
  • MakerDAO to allow users to lend small amounts backed by their Reddit community points.
  • STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.

Cost

Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.
Dragonchain Fees Table

Getting Started

How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
  • While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
  • Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.

Costs and resources

Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.

Requirements

Scaling

This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.
Over a 5 day period, your scaling PoC should be able to handle:
*100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum

Decentralization

Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
  • Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
  • Operational multi-cloud
  • Operational on-premises capabilities
  • Operational deployment to any datacenter
  • Over 700 independent Community Verification Nodes with proof of ownership
  • Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)

Usability Scaling solutions should have a simple end user experience.

Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Examples:

Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.

Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees

Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.

Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.

Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.

Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
APIs should be well documented and stable

Documentation should be clear and complete
For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.

Bonus

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.

Dragon Den

Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.

Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.

Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.

Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw

Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.

A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.

Bonus points
Public, third-party implementation review available or in progress
See above

Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.

Other Considerations

Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.

One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).

Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).

Conclusion

Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!

Disney Releases Blockchain Platform as Open Source

The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html

Open Source

In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
  • Obtain VP support and approval for the release
  • Verify ownership of the software to be released
  • Verify that no proprietary content would be released
  • Convince the organization that there was a value to the open source community
  • Convince the organization that there was a value to Disney
  • Offer the plan for ongoing maintenance of the project outside of Disney
  • Itemize competing projects
  • Verify no conflict of interest
  • Preferred license
  • Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
  • Obtain legal approval
  • Approval from corporate, parks, and other business units
  • Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
  • Trademark searches conducted for the selected name Dragonchain
  • Obtain IT security approval
  • Manual review of OSS components conducted
  • OWASP Dependency and Vulnerability Check Conducted
  • Obtain technical (software) approval
  • Offer management, process, and financial plans for the maintenance of the project.
  • Meet list of items to be addressed before release
  • Remove all Disney project references and scripts
  • Create a public distribution list for email communications
  • Remove Roets’ direct and internal contact information
  • Create public Slack channel and move from Disney slack channels
  • Create proper labels for issue tracking
  • Rename internal private Github repository
  • Add informative description to Github page
  • Expand README.md with more specific information
  • Add information beyond current “Blockchains are Magic”
  • Add getting started sections and info on cloning/forking the project
  • Add installation details
  • Add uninstall process
  • Add unit, functional, and integration test information
  • Detail how to contribute and get involved
  • Describe the git workflow that the project will use
  • Move to public, non-Disney git repository (Github or Bitbucket)
  • Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney.
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

Don't blindly follow a narrative, its bad for you and its bad for crypto in general

I mostly lurk around here but I see a pattern repeating over and over again here and in multiple communities so I have to post. I'm just posting this here because I appreciate the fact that this sub is a place of free speech and maybe something productive can come out from this post, while bitcoin is just fucking censorship, memes and moon/lambo posts. If you don't agree, write in the comments why, instead of downvoting. You don't have to upvote either, but when you downvote you are killing the opportunity to have discussion. If you downvote or comment that I'm wrong without providing any counterpoints you are no better than the BTC maxis you despise.
In various communities I see a narrative being used to bring people in and making them follow something without thinking for themselves. In crypto I see this mostly in BTC vs BCH tribalistic arguments:
- BTC community: "Everything that is not BTC is shitcoin." or more recently as stated by adam on twitter, "Everything that is not BTC is a ponzi scheme, even ETH.", "what is ETH supply?", and even that they are doing this for "altruistic" reasons, to "protect" the newcomers. Very convenient for them that they are protecting the newcomers by having them buy their bags
- BCH community: "BTC maxis are dumb", "just increase block size and you will have truly p2p electronic cash", "It is just that simple, there are no trade offs", "if you don't agree with me you are a BTC maxi", "BCH is satoshi's vision for p2p electronic cash"
It is not exclusive to crypto but also politics, and you see this over and over again on twitter and on reddit.
My point is, that narratives are created so people don't have to think, they just choose a narrative that is easy to follow and makes sense for them, and stick with it. And people keep repeating these narratives to bring other people in, maybe by ignorance, because they truly believe it without questioning, or maybe by self interest, because they want to shill you their bags.
Because this is BCH community, and because bitcoin is censored, so I can't post there about the problems in the BTC narrative (some of which are IMO correctly identified by BCH community), I will stick with the narrative I see in the BCH community.
The culprit of this post was firstly this post by user u/scotty321 "The BTC Paradox: “A 1 MB blocksize enables poor people to run their own node!” “Okay, then what?” “Poor people won’t be able to use the network!”". You will see many posts of this kind being made by u/Egon_1 also. Then you have also this comment in that thread by u/fuck_____________1 saying that people that want to run their own nodes are retarded and that there is no reason to want to do that. "Just trust block explorer websites". And the post and comment were highly upvoted. Really? You really think that there is no problem in having just a few nodes on the network? And that the only thing that secures the network are miners?
As stated by user u/co1nsurf3r in that thread:
While I don't think that everybody needs to run a node, a full node does publish blocks it considers valid to other nodes. This does not amount to much if you only consider a single node in the network, but many "honest" full nodes in the network will reduce the probability of a valid block being withheld from the network by a collusion of "hostile" node operators.
But surely this will not get attention here, and will be downvoted by those people that promote the narrative that there is no trade off in increasing the blocksize and the people that don't see it are retarded or are btc maxis.
The only narrative I stick to and have been for many years now is that cryptocurrency takes power from the government and gives power to the individual, so you are not restricted to your economy as you can participate in the global economy. There is also the narrative of banking the bankless, which I hope will come true, but it is not a use case we are seeing right now.
Some people would argue that removing power from gov's is a bad thing, but you can't deny the fact that gov's can't control crypto (at least we would want them not to).
But, if you really want the individuals to remain in control of their money and transact with anyone in the world, the network needs to be very resistant to any kind of attacks. How can you have p2p electronic cash if your network just has a handful couple of nodes and the chinese gov can locate them and just block communication to them? I'm not saying that this is BCH case, I'm just refuting the fact that there is no value in running your own node. If you are relying on block explorers, the gov can just block the communication to the block explorer websites. Then what? Who will you trust to get chain information? The nodes needs to be decentralized so if you take one node down, many more can appear so it is hard to censor and you don't have few points of failure.
Right now BTC is focusing on that use case of being difficult to censor. But with that comes the problem that is very expensive to transact on the network, which breaks the purpose of anyone being able to participate. Obviously I do think that is also a major problem, and lightning network is awful right now and probably still years away of being usable, if it ever will. The best solution is up for debate, but thinking that you just have to increase the blocksize and there is no trade off is just naive or misleading. BCH is doing a good thing in trying to come with a solution that is inclusive and promotes cheap and fast transactions, but also don't forget centralization is a major concern and nothing to just shrug off.
Saying that "a 1 MB blocksize enables poor people to run their own" and that because of that "Poor people won’t be able to use the network" is a misrepresentation designed to promote a narrative. Because 1MB is not to allow "poor" people to run their node, it is to facilitate as many people to run a node to promote decentralization and avoid censorship.
Also an elephant in the room that you will not see being discussed in either BTC or BCH communities is that mining pools are heavily centralized. And I'm not talking about miners being mostly in china, but also that big pools control a lot of hashing power both in BTC and BCH, and that is terrible for the purpose of crypto.
Other projects are trying to solve that. Will they be successful? I don't know, I hope so, because I don't buy into any narrative. There are many challenges and I want to see crypto succeed as a whole. As always guys, DYOR and always question if you are not blindly following a narrative. I'm sure I will be called BTC maxi but maybe some people will find value in this. Don't trust guys that are always posting silly "gocha's" against the other "tribe".
EDIT: User u/ShadowOfHarbringer has pointed me to some threads that this has been discussed in the past and I will just put my take on them here for visibility, as I will be using this thread as a reference in future discussions I engage:
When there was only 2 nodes in the network, adding a third node increased redundancy and resiliency of the network as a whole in a significant way. When there is thousands of nodes in the network, adding yet another node only marginally increase the redundancy and resiliency of the network. So the question then becomes a matter of personal judgement of how much that added redundancy and resiliency is worth. For the absolutist, it is absolutely worth it and everyone on this planet should do their part.
What is the magical number of nodes that makes it counterproductive to add new nodes? Did he do any math? Does BCH achieve this holy grail safe number of nodes? Guess what, nobody knows at what number of nodes is starts to be marginally irrelevant to add new nodes. Even BTC today could still not have enough nodes to be safe. If you can't know for sure that you are safe, it is better to try to be safer than sorry. Thousands of nodes is still not enough, as I said, it is much cheaper to run a full node as it is to mine. If it costs millions in hash power to do a 51% attack on the block generation it means nothing if it costs less than $10k to run more nodes than there are in total in the network and cause havoc and slowing people from using the network. Or using bot farms to DDoS the 1000s of nodes in the network. Not all attacks are monetarily motivated. When you have governments with billions of dollars at their disposal and something that could threat their power they could do anything they could to stop people from using it, and the cheapest it is to do so the better
You should run a full node if you're a big business with e.g. >$100k/month in volume, or if you run a service that requires high fraud resistance and validation certainty for payments sent your way (e.g. an exchange). For most other users of Bitcoin, there's no good reason to run a full node unless you reel like it.
Shouldn't individuals benefit from fraud resistance too? Why just businesses?
Personally, I think it's a good idea to make sure that people can easily run a full node because they feel like it, and that it's desirable to keep full node resource requirements reasonable for an enthusiast/hobbyist whenever possible. This might seem to be at odds with the concept of making a worldwide digital cash system in which all transactions are validated by everybody, but after having done the math and some of the code myself, I believe that we should be able to have our cake and eat it too.
This is recurrent argument, but also no math provided, "just trust me I did the math"
The biggest reason individuals may want to run their own node is to increase their privacy. SPV wallets rely on others (nodes or ElectronX servers) who may learn their addresses.
It is a reason and valid one but not the biggest reason
If you do it for fun and experimental it good. If you do it for extra privacy it's ok. If you do it to help the network don't. You are just slowing down miners and exchanges.
Yes it will slow down the network, but that shows how people just don't get the the trade off they are doing
I will just copy/paste what Satoshi Nakamoto said in his own words. "The current system where every user is a network node is not the intended configuration for large scale. That would be like every Usenet user runs their own NNTP server."
Another "it is all or nothing argument" and quoting satoshi to try and prove their point. Just because every user doesn't need to be also a full node doesn't mean that there aren't serious risks for having few nodes
For this to have any importance in practice, all of the miners, all of the exchanges, all of the explorers and all of the economic nodes should go rogue all at once. Collude to change consensus. If you have a node you can detect this. It doesn't do much, because such a scenario is impossible in practice.
Not true because as I said, you can DDoS the current nodes or run more malicious nodes than that there currently are, because is cheap to do so
Non-mining nodes don't contribute to adding data to the blockchain ledger, but they do play a part in propagating transactions that aren't yet in blocks (the mempool). Bitcoin client implementations can have different validations for transactions they see outside of blocks and transactions they see inside of blocks; this allows for "soft forks" to add new types of transactions without completely breaking older clients (while a transaction is in the mempool, a node receiving a transaction that's a new/unknown type could drop it as not a valid transaction (not propagate it to its peers), but if that same transaction ends up in a block and that node receives the block, they accept the block (and the transaction in it) as valid (and therefore don't get left behind on the blockchain and become a fork). The participation in the mempool is a sort of "herd immunity" protection for the network, and it was a key talking point for the "User Activated Soft Fork" (UASF) around the time the Segregated Witness feature was trying to be added in. If a certain percentage of nodes updated their software to not propagate certain types of transactions (or not communicate with certain types of nodes), then they can control what gets into a block (someone wanting to get that sort of transaction into a block would need to communicate directly to a mining node, or communicate only through nodes that weren't blocking that sort of transaction) if a certain threshold of nodes adheres to those same validation rules. It's less specific than the influence on the blockchain data that mining nodes have, but it's definitely not nothing.
The first reasonable comment in that thread but is deep down there with only 1 upvote
The addition of non-mining nodes does not add to the efficiency of the network, but actually takes away from it because of the latency issue.
That is true and is actually a trade off you are making, sacrificing security to have scalability
The addition of non-mining nodes has little to no effect on security, since you only need to destroy mining ones to take down the network
It is true that if you destroy mining nodes you take down the network from producing new blocks (temporarily), even if you have a lot of non mining nodes. But, it still better than if you take down the mining nodes who are also the only full nodes. If the miners are not the only full nodes, at least you still have full nodes with the blockchain data so new miners can download it and join. If all the miners are also the full nodes and you take them down, where will you get all the past blockchain data to start mining again? Just pray that the miners that were taken down come back online at some point in the future?
The real limiting factor is ISP's: Imagine a situation where one service provider defrauds 4000 different nodes. Did the excessive amount of nodes help at all, when they have all been defrauded by the same service provider? If there are only 30 ISP's in the world, how many nodes do we REALLY need?
You cant defraud if the connection is encrypted. Use TOR for example, it is hard for ISP's to know what you are doing.
Satoshi specifically said in the white paper that after a certain point, number of nodes needed plateaus, meaning after a certain point, adding more nodes is actually counterintuitive, which we also demonstrated. (the latency issue). So, we have adequately demonstrated why running non-mining nodes does not add additional value or security to the network.
Again, what is the number of nodes that makes it counterproductive? Did he do any math?
There's also the matter of economically significant nodes and the role they play in consensus. Sure, nobody cares about your average joe's "full node" where he is "keeping his own ledger to keep the miners honest", as it has no significance to the economy and the miners couldn't give a damn about it. However, if say some major exchanges got together to protest a miner activated fork, they would have some protest power against that fork because many people use their service. Of course, there still needs to be miners running on said "protest fork" to keep the chain running, but miners do follow the money and if they got caught mining a fork that none of the major exchanges were trading, they could be coaxed over to said "protest fork".
In consensus, what matters about nodes is only the number, economical power of the node doesn't mean nothing, the protocol doesn't see the net worth of the individual or organization running that node.
Running a full node that is not mining and not involved is spending or receiving payments is of very little use. It helps to make sure network traffic is broadcast, and is another copy of the blockchain, but that is all (and is probably not needed in a healthy coin with many other nodes)
He gets it right (broadcasting transaction and keeping a copy of the blockchain) but he dismisses the importance of it

RiB Newsletter #16 – Secure Enclaves à la Crab

For the last few months we’ve been following new zero-knowledge proof projects in Rust. This month, with Secret Network upgrading their mainnet with secret contracts, it seems like a good opportunity to explore Rust blockchains that are using a completely different privacy-preserving technology: secure enclaves.
Secure enclaves are processes whose environment is protected from inspection by other processes, even the kernel, by special hardware. This protection particularly involves the encryption of a process’s memory. Software that wants to compute in secret can put those computations inside a secure enclave and, if everything works as expected, neither a local user, nor the hosting provider, can snoop on the computations being performed. The most notable implementation of secure enclaves is Intel’s SGX (Secure Guard Extensions).
Secure enclaves are an attractive way to perform private computation primarily because they don’t impose any limitations on what can be computed — code that runs inside SGX is more-or-less just regular x86 code, just running inside a special environment. But depending on SGX for privacy does have some special risks: software that runs in an SGX enclave must be signed (if transitively) by Intel’s own cryptographic keys, which means that Intel must approve of any software running in SGX, that Intel can revoke permission to use SGX, and that there is a risk of the signing keys being compromised; and it’s not obvious that secure enclaves are actually secure, there have already been a number of attacks against SGX. Regardless, as of now, hardware enclaves provide security features that aren’t feasible any other way.
There are two prominent Rust blockchains relying on SGX:
Outside of the blockchain world there are some other Rust projects using SGX, the most notable being:
Whether it’s secure enclaves or zk-SNARKs, Rust blockchains are walking the bleeding edge of privacy tech.
In unrelated RiB news, we recently received two donations,
Thanks so much to our anonymous donors. We don’t often receive donations, so this was a nice surprise! We intend to put all monetary contributions to use funding events or new contributors, and we’ll let you know what we do with the funds when we spend them.

Project Spotlight

Each month we like to shine a light on a notable Rust blockchain project. This month that project is…
Aleo.
Aleo is a zero-knowledge blockchain, with its own zero-knowledge programming language, Leo.
We don’t have a lot to say about it, but we think it looks cool. We hope they blog more.

Updated list of Global Beermoney opportunities (+180!) - June 2020

Updated list of Global Beermoney opportunities (+180!) - June 2020

Introduction

The current, and now previous, Beermoney Global list started nearly 5 years ago. It’s been updated and has grown over all that time, but it also became a hassle to keep current. It was time to build a new list from scratch based on my experience in the Beermoney world over all these years and all the contributions all of you have been making in this sub.
The lists consist of opportunities that are available in at least one country that is not the US. This means there are sites which only work in Canada or the UK. There’s sites which are open to the whole world, but this does not mean everyone can really earn something on it. It’s all still very demographic and therefore location dependent. This list should give you a starting point to try out and find what works for you. I’m not using everything myself as I prefer to focus on a few, so not all are tested by me. They are found in this sub, other subreddits and other resources where people claim to have success.
I’ve chosen the format of a simple table with the bare minimum of information to keep things clean. It includes a link, how you earn, personal payment proof if available and sign-up bonus codes if applicable. Some of these bonuses are also one-time use codes specifically made for this sub! For the ones I don’t have payment proof (yet) feel free to provide some as a comment or via modmail so others know it’s legit. I am working on detailed instructions for each method that I personally use which will include things like cashout minimum, cashout options, tips & tricks,... For now I’ve split things up based on the type of earning like passive or mobile. Because of this there’s sometimes an overlap as some are both passive and on mobile or both earning crypto and a GPT (Get Paid To) website.
The lists are obviously not complete so I invite you to keep posting new ones in the sub, as a comment to this post, or in modmail. Especially if you have sites or apps which work for one single specific country I can start building a list, just like I did for The Netherlands and Belgium. If you recognize things which are in fact scams or not worth it let me know as well.

The Netherlands specific
For The Netherlands there are a few very good options next to a bunch of ‘spaarprogramma’s. There ‘spaarprogramma’s are all the same where you receive and click a bunch of e-mails, advertisements, banners,... I advise you to create a separate e-mail address or use a good filter in your inbox as you will be spammed to death. I believe they can be a nice piece of beermoney but they take quite the effort.
