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.
else if's and lack any sort of refactoring in general
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.
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.
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.
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.
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.
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:
Fix the code (unavoidable time loss)
Rebuild the project (can take a loooong time)
Load your game (can take a loooong time)
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.
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.
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.
Hello all, first thing first, I am a computer repair technician at a Bitcoin mining facility. We have about 20,000 bitcoin miners that me and my coworkers are in charge of monitoring and repairing. So with that being said I am pretty much lost when it comes to python and servers and things of that sort.Everyone that has dealt with computers/electronics know that heat is a huge issue. And heat is a killer to bitcoin miners,so monitoring the temperature and humidity in the facility is crucial so we can control the waterwalls and such as needed .I have successfully set up 14 raspberry pis with DHT22 sensors by copying and pasting scripts that I found online. They are reporting to a website through POST method. The readings are shown on a barchart,but is not dynamic so it only shows 1 reading at a time. I have been tasked with setting up a way to get all the sensors reading to a single server,then pulling the data from the server onto a D3.js grouped bar chart . Now, there is 14 Pis and each is set to read every mintue. These will be running 24/7 so there will be alot of readings. My question,actually a few questions is I am needing to set up 1 Pi as a dedicated server receiving all the readings. 1)What would be the best way to set that up,I have read that a MQTT server is the easiest but cant handle a lot of data(which I will have)I was thinking about a MySql. 2)Would I need to attach extra storage to this Pi to handle all the data. 3) How do I send all the readings to the server Pi(NOTE: they will all be on the same network) 4) How would I pull all this information from the server and input it into a D3.js grouped bar chart. Do I need to have a web server installed on the Pi?. I'm not expecting a step by step answer, and I am on a timeline and honestly dont have time to learn pythhon,html,php,sql or whatever is needed for this. All I am asking is for is a step in the right direction, thanks to all that read this and any information will be greatly appreciated

This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number Bitcoin Fork - Suitable for Home Hobbyists NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs. The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

Life is difficult when one is out of a activity but it’s worse when one retires with out some thing sizable to reveal for it, work is taxing health-clever and labour-smart and time sensible, so one prepares for vintage age and retirement with diverse plans and procedures, some are trying to find to spend money on treasury bonds, mutual price range, stocks, startups, 401k, actual estate and so forth however best few genuinely get to have profitable investments. Investing is complex, one is confronted with the demanding situations of data and the option of choosing from a plethora of funding options. https://preview.redd.it/5nzeo7bw2ng51.jpg?width=225&format=pjpg&auto=webp&s=1ac29a6c033750f5e83c64a26559d5d2c72f7fee Gold is an asset known to man over hundreds of a while,Gold and copper were the primary metals utilized by human beings starting from 5000 BC, The first registered gold determined inside the u.S.A. Become a nugget weighing 7.8kg located in cabarrus county, North Carolina. When more gold become discovered in little creek meadow in 1803, the primary US gold rush commenced. The world’s biggest gold reserve is held 5 stories underground inside the vault of the Federal Reserve Bank of New York, it includes 25% of all of the gold reserves within the international (540,000 gold bars), most of them belong to foreign govts. The first-ever gold vending system become established in Dubai in 2010. Due to its rarity and high price, maximum of the gold ever mined continues to be in circulating gold become extracted inside the last one hundred years. Many humans ask why gold is so highly-priced, the cause is its rarity: extra metallic is produced in a single hour than gold over the course of the complete human history. Many scientists agree with that gold is also found in Mars, Mercury and Venus. https://preview.redd.it/5oc3swd13ng51.jpg?width=225&format=pjpg&auto=webp&s=e412a2469107996f14bea028fdc8e0c9cf3198fa Reports say China is growing its gold imports and Mark Mobius,an avid dealer in gold has counseled that people purchase gold, he believes that the rate of gold will keep developing as the amount of paper money in the worldwide financial system will increase. Do you know that less than 82% of USA citizens personal any piece of gold? The buying and selling extent of digital gold is over $100 m. Do you understand you can also invest in gold? Lets speak approximately the possibilities of making an investment in gold the use of a blockchain platform, how about you are able to have one piece of gold that has a token representation, Today, we can communicate about the virtual gold token, what it does and the way you could sincerely advantage from it. Now, if you are following closely,you may find out that the crypto marketplace hit its height in 2017, in 2017 bitcoin become selling for $20,000 and in 2020, it's miles floating around $9,000 and each extreme investor need to be searching at this marketplace, at 2017 the entire market capitalization of crypto currencies was almost $1 Trillion dollars and although it has fallen to round $300 billion bucks in 2020, this enterprise nonetheless holds a number of capacity. https://preview.redd.it/cd1haqc73ng51.jpg?width=303&format=pjpg&auto=webp&s=5f033787e8d83dcc4165683cdcd3e9d90bfb29db One should be asking why is there so much investment going into the blockchain space, what's the capacity that this element have, many have dubbed blockchain as net 3.0 or the last technology that will bring in internet 3.0, till date, the investments which have long gone through numerous blockchain startups have been over $25 billion greenbacks with the likes of EOS, Telegram raising billions of greenbacks each.
What are the troubles concerned in investing in cryptocurrencies
Volatility: If you study the altcoin alltime index, you may see the disgusting drop in crypto fee
Storage: Knowing which coins to buy and the way to keep them is a huge hassle in the crypto currency global, crypto jacking and hacking are at the all time high as hackers have infested maximum internet browsers with coin mining scripts and just last year over $1 billion greenbacks well worth of crypto belongings were stolen from numerous exchanges which in turn forced them to shut their doorways.
The idea is aimed at breaking complete units of stocks,infrastructure and so on into smaller pix, Take one unit of gold and make a virtual unit of it with the blockchain,that concept surely birthed the Digital gold token mission, The digital gold market:allows facilitate a tremendously smooth, effective and efficient purchase/sale machine, users can sincerely fill out a shape that initiates a smart settlement, which then transfers the newly-minted GOLD tokens. As for builders,they're additionally stored the hassle of the complexities that include integrating a crypto asset to their platform,the digital gold initiatives help them combine without problems. https://preview.redd.it/gh76zlto3ng51.jpg?width=299&format=pjpg&auto=webp&s=96198a60fd7a222f4d2e55b7ce76a8dc9160b820
Features of Digital Gold
The virtual gold token boosts some of features that makes it particular and profitable for capacity investors to inspect.
It’s a token this is low price and does no longer have have switch prices when one is shifting it, it gives capacity investors the opportunity to diversify their portfolio even as also retaining their wealth in a safe haven, it additionally gives at ease gold possession as the purchased gold in secured in a safe vault, the digital gold token is pretty liquid, which means there may be a market for you each time you ought to promote or buy the token, since the digital gold token is tied to real gold, the token is as precious as gold itself, in order gold will increase in value so does the token.

It’s the smartest crypto you’ve never heard of. Ergo takes the best of Bitcoin and integrates Sigma protocols so powerful they make Ethereum look like it would lose a game of chess against your cat. If you’re tired of spin and hype over solid tech, Ergo will remind you that in crypto, it’s always been fashionable to be intelligent. Bright is the new black, people, and Ergo is set to dazzle you. DeFi is set to be the major blockchain trend for 2020. Many new smart contract platforms are positioning to become one of the handful of big players in the space. With a strong head start, competent development team and impressive network, Ethereum’s place in this billion-dollar (and growing) movement is assured. The others must offer something different – dramatically different – to differentiate themselves against this background. Ergo is a smart contracts and DeFi platform that may have what it takes to carve out a niche in this fast-moving and competitive new sector. Powerful But Safe Contracts Ethereum is an exceptional platform, but there are things it does not do well. Its Turing-complete smart contracts are powerful, but dangerous – as incidents from The DAO to the Parity wallet exploits have proven, with tens of millions of dollars in collateral damage. With complexity comes uncertainty, and potentially catastrophic vulnerabilities. Contracts can be expensive to run, and depending on network conditions may execute unpredictably – or not at all. Ergo takes a fundamentally different approach to smart contract development. The team, which has extensive experience with blockchain platforms, frameworks and organisations from Nxt and Waves to Scorex and IOHK, has adopted a declarative model for programming whereby it’s always known in advance how much code will cost to run – and, indeed, whether it will run precisely as intended. While that might on the surface limit code complexity, it’s nevertheless possible to create Turing-complete scripts by iterating processes across multiple blocks. That means Ergo can support versatile dApps that run predictably, with known costs, and don’t have any of the dangers of unrestricted functionality. Sigma protocols The platform is unashamedly conservative, basing as many features as possible on Bitcoin – after all, Bitcoin is the most battle-tested crypto network in existence. Ergo’s UTXO model, PoW mining and finite supply draw on Bitcoin’s approaches to consensus and economic incentives. But Ergo also incorporates cutting-edge research into new cryptographic processes, using Sigma protocols to enable DeFi applications that would be either complex and messy or simply impossible on other platforms. Sigma protocols are a well-known class of zero-knowledge proofs that allow developers to implement very powerful processes very elegantly. For example, what if you want to build a privacy service that allows any one of a dozen different accounts to spend funds from an address – but no one can tell who has made each transfer? Such a ‘ring contract’ is possible with Ethereum, but it would require a clunky and expensive workaround. With Ergo’s Sigma protocols, it’s possible to implement this kind of use case and many others quickly, efficiently and – above all – securely. Sigma protocols have not been deployed in such generic form within crypto before. Yet this kind of out-of-the-box functionality is hugely valuable, especially when no other DeFi platform offers it. Get involved Ergo’s team has been working on the project for over two years, attracting interest from some major players in the crypto space (including Cardano’s Charles Hoskinson) but avoiding mainstream attention until now. With the platform’s core functionality now substantially complete, the developers are seeking to expand the network, form new partnerships and make a mark in the nascent DeFi movement.

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything. The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years. In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.
UPDATED - Groestlcoin Core 2.18.2
This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables. NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.
How to Upgrade?
Windows If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer. OSX If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications. Ubuntu http://groestlcoin.org/forum/index.php?topic=441.0
ALL NEW - Groestlcoin Moonshine iOS/Android Wallet
Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network. GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled. HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user. Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.
Simplified payment verification for fast mobile performance
Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases. This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats. To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator. VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline. If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address. VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase. VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet. If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)
Show and hide the private key with a simple toggle switch
Show full output of commands
Ability to choose between Processor (CPU) and Graphics Card (GPU) ( NVidia ONLY! )
Features both a Light and Dark Material Design-Style Themes
Free software - MIT. Anyone can audit the code.
Written in C# - The code is short, and easy to review.
Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node. It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node. Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine. Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in. Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet. Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX
UPDATED – Android Wallet 7.38.1 - Main Net + Test Net
The app allows you to send and receive Groestlcoin on your device using QR codes and URI links. When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.
Add confidence messages, helping users to understand the confidence state of their payments.
Handle edge case when restoring via an external app.
Count devices with a memory class of 128 MB as low ram.
Introduce dark mode on Android 10 devices.
Reduce memory usage of PIN-protected wallets.
Tapping on the app's version will reveal a checksum of the APK that was installed.
Fix issue with confirmation of transactions that empty your wallet.
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.
The first and foremost thing to know about Leasehold platform is that it is decentralized that is to say, it is based on blockchain. Leasehold is also a profit-sharing business or platform with the sole purpose of sharing rental income via tokenization brought about by blockchain. In the same way, it is good to know that, the Leasehold platform aims to be a valuable one and to achieve this, sees it fit to ensure their token holders are always comfortable hence the idea of rewards being in the form of buy-back and burn; with this strategy, the Leasehold platform take the acquired profits, buys back its tokens from the market and burn them. In other ways, Leasehold token is a Deflationary token which will continue to be bought and burnt as the platform ensures strict growth policies are followed.
Like earlier stated, there are many blockchain projects with different consensus algorithms such as Proof-of-Stake, Proof-of-Work etc, in the case of Leasehold, it will be based on Delegated Proof-of-Stake (DPOS). This DPOS is of the idea that delegates within the platform can create blocks, these delegates are trusted and as such selected to be active within the platform in addition to the fact they secure the chain while getting their rewards which is strictly based on a good performance.
Talking about a decentralized exchange, it offers more security because, in the crypto space, there are many exchanges that have been hacked, exit scam with funds as well as closing accounts without reason. Therefore, Leasehold will sure have its own because the team wants to offer a secure, safe, trustworthy and reliable platform for trading of LSH tokens. When trading in Leasehold platform's DEX, there will be no malicious acts but instead a good level of trust and transparency.
Another point as to why Leasehold is worthwhile is the fact that it makes it possible for users to partake in profit-sharing without owning properties physically, nor is there a need to identify themselves. In view of this, Leasehold is working towards taking huge advantages of the tourist industry, everyday living industry etc since it has been proven that booking platforms grow with more than double the users from the previous years. With this move, as a user, there is an opportunity to profit by owning the property, while with Leasehold, everything is simplified leading to owning a portion of profits.
Another wonderful attribute of Leasehold platform is that token holders are carried along in the development of the platform, in this case, they are always presented with updated happenings which includes buy-back details, acquisition of properties etc.
Since security is paramount in Leasehold platform, the team created a hub, which will make it possible for token holders to securely store their tokens in their wallet. This wallet is connected directly to the Leasehold network.
There are many projects already in the crypto space which supports mining and same is the case with Leasehold. Leasehold will have a real-time data pool bearing all the financials of the platform's earnings. It will also display a list of the current buy-back funds which will be used for buy-back and burn purposes.
Currently, many people in the world are limited when it comes to using of cryptocurrencies and this is where tokenization comes to play; that is, with tokenization, many people in the world will be free and able to buy crypto easily. With this in mind, in the Leasehold platform is tokenization as well, with tokenization of LSH tokens, people from all over the world will be able to take part in profit-sharing from the Leasehold short term rental markets. This is profitable because a study has shown that, short term rental markets are now booming all over the world because there is no need putting up large amounts of capital at once, which many individuals do not have or have access to.
There are two methods of property rental in Leasehold platform which is developed to accommodate different types of users; a. Property rental of non-owned apartments: This is a method where the Leasehold team will accept the responsibility of running apartments for homeowners which will be at an agreed amount. In this case, the team will use their marketing strategies and booking system methods to ensure the best of services is offered to homeowners while on the other hand, this will also help Leasehold to acquire constant funding for its buybacks. b. Property rental of owned properties: In this method, the Leasehold team will strive to achieve the maximum amount of returns since all profits will belong to the company at the same time distributed to the buybacks. Furthermore, from the profits made, Leasehold will continue buying property on the open market while renting it out using its specially designed cross-platform method.
Just like there are blockchain platforms which sought for funding before continuing building their platform, same is with Leasehold. The team will carry out 5 stages of ITO’s with the aim of raising enough funding so as to acquire small apartments thus starting the renting process and partner site setups. According to the team, the reason for these stages of ITO is that each stage will allow the Leasehold platform to acquire and set up the working business model that will make the buy-back and burn process possible. The end result of this is, Leasehold will be in a position to be free from cryptocurrencies volatility as well as being far bear markets. Leasehold Initial Token Offering (ITO) has started already and stipulated to end by May 2020.

AMA Recap of CEO and Co-founder of Chromia, Henrik Hjelte in the @binancenigeria Telegram group on 03/05/2020.
Bitcoin is by far the most successful cryptocurrency. After ten years of development, the concept of Bitcoin as a community currency has gained widespread acceptance. With the participation of more and more miners, exchanges, developers, and ordinary users, the network effect of Bitcoin is strong and growing. According to the latest data from CoinMarketCap, Bitcoin Dominance accounts for 65.4% of the total market value of cryptocurrency, which is unmatched by any other blockchain project. However, this huge network effect has not spawned more valuable applications on the Bitcoin network. This is mainly due to the non-Turing complete script of Bitcoin, which cannot support the implementation of complex logic. Although Bitcoin uses non-Turing-complete scripts for security reasons, this undoubtedly sacrifices more possibilities for the Bitcoin ecosystem and hinders the further expansion of its network effect. Smart contracts are Turing complete and can be used to develop complex DApps. But even though Ethereum and other blockchain projects support smart contracts, the user base and network effects pale in comparison to Bitcoin. https://preview.redd.it/r2mqkqsv0oq41.jpg?width=1400&format=pjpg&auto=webp&s=52f63dcf895b04b719fcde0b08054479706fd050
BSC = Bitcoin Users + Smart Contracts
https://preview.redd.it/xmgdkzwx0oq41.jpg?width=1400&format=pjpg&auto=webp&s=63ab187873f9364779fe5a13506ad2a015c55d73 We propose BSC (Bitcoin Smart Contract) in the whitepaper https://docs.bsc.net/en/bsc_en.pdf BSC will be a hard fork of Bitcoin, inheriting all the transaction history of Bitcoin, and will support smart contracts with unlimited flexibility. With the original user base and network effects of Bitcoin, BSC will enable DApps with real value. Bitcoin users + smart contracts are likely to bring the entire industry into a new phase. Applications in the original smart contract ecosystem will likely bring qualitative changes with the help of Bitcoin’s network effect: BTC + Digital Assets. Bitcoin users and developers will be able to issue digital assets similar to ERC-20 on the BSC network. The Bitcoin network effect makes these assets potentially more useful and valuable. BTC + DeFi. Similar to MakerDAO, decentralized lending and fund custody, stablecoins, etc. will be built on the user base of Bitcoin to gain greater scale and visibility with the leading crypto asset. BTC + Privacy Protocol. Since Bitcoin assets account for a very high proportion in the entire industry, Bitcoin users’ need for privacy is even more urgent. A smart contract-based privacy protocol can be built in the BSC ecosystem, and Bitcoin users can use this to achieve asset privacy. BTC + DApp. Bitcoin users can directly create various DApps in the BSC network, such as decentralized exchanges, decentralized games, and decentralized domain name services. These applications are not mainstream now, but given the huge network effect of Bitcoin, there will be more DApps that can prove their value.
Compatibility with Bitcoin Ecosystem
To provide the huge network effect of Bitcoin, BSC is technically compatible with Bitcoin in terms of the underlying architecture and network parameters: The infrastructure layer of the BSC adopts the UTXO (Unspent Transaction Output) model that is completely consistent with Bitcoin, supports all script types of Bitcoin, and naturally supports SegWit, multi-sig, etc. Compared with the account model, the UTXO model has certain advantages in terms of security, anonymity, and parallelism, and supports SPV (Simple Payment Verification), which makes it easier to support light wallets. Due to the consistency of the underlying architecture, BSC is naturally compatible with the Bitcoin ecosystem. For example, all types of Bitcoin wallets, browsers, and Layer-2 protocols (such as the Lightning Network) can directly support BSC, and users have no limits. Also, the upper limit of the total supply of BSC, the inflation rate, and the halving period are all consistent with Bitcoin. BSC will also inherit all the transaction history data of Bitcoin. Bitcoin users will obtain the equivalent BSC 1: 1. All subsequent BSC coins will be generated by PoW mining, and the development team will not have any pre-mining or pre-allocation of any coins.
Compatibility with Smart Contracts
Virtual machines are the execution environment of smart contracts. Based on maintaining the above compatibility with Bitcoin’s underlying infrastructure, BSC has achieved compatibility with EVM (Ethereum Virtual Machine) by adding additional scripts and intermediate layers, so that it can theoretically support all smart contracts in the Ethereum ecosystem. Popular applications in the Ethereum ecosystem, such as MakerDAO, AZTEC privacy protocol, decentralized stablecoins, etc., can be directly ported to the BSC network. Although these applications have received some attention on Ethereum, restrictions on the Ethereum network has significantly limited their further development. For example, decentralized lending, if you rely on the stability of Bitcoin assets and the participation of Bitcoin users, you will get more room for development.
Mining Algorithm and Reward
BSC uses the PoW consensus mechanism. Unlike Bitcoin, BSC uses the newer SHA-3 + Blake2b mining algorithm. Bitcoin’s computing power is mainly controlled by several large Bitcoin mining pools. If BSC used a PoW mining algorithm the same as Bitcoin or any mining algorithm that already has ASIC miners, there would be a good possibility for the network to suffer 51% attacks during the initial startup. To reduce the risk of attack and keep the network sufficiently decentralized, BSC uses the SHA-3 + Blake2b hash algorithm. This algorithm has been verified in projects such as Handshake, and currently, there is no ASIC miner available, which helps ensure the stable development of the BSC network. As a BSC miner, in addition to the block rewards and transaction fees like Bitcoin, the block rewards will include the gas cost of smart contracts. Every halving of bitcoin brings significant challenges to miners. When the future bitcoin block reward is reduced to zero, whether transaction fees can support miners’ income is still unknown. The introduction of smart contracts will give BSC miners a source of additional revenue, further encourage miners to participate in mining, and protect the security of the network.
You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments. The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
Limited Supply - There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary. The halving countdown can be found here.
Open source - Bitcoin code is fully auditable. You can read the source code yourself here.
Accountable - The public ledger is transparent, all transactions are seen by everyone.
Decentralized - Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can't be shut down similar to how Bittorrent works.
Censorship resistant - No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
Push system - There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
Low fee - Transactions fees can vary between a few cents and a few dollars depending on network demand and how much priority you wish to assign to the transaction. Most wallets calculate the fee automatically but you can view current fees here.
Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.
Where can I buy bitcoins?
BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also, check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or Bitwage. Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".
Securing your bitcoins
With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, there are many software wallet options here. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor or Ledger is recommended. A more advanced option is to secure them yourself using paper wallets generated offline. Some popular mobile and desktop options are listed below and most are cross platform.
If you prefer to let third party "Bitcoin banks" manage your coins, try Coinbase or Xapo but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash. Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email! 2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out. If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. Bitseed is an easy option for getting set up. You can view the global node distribution here.
Just like any other form of money, you can also earn bitcoins by being paid to do a job.
You can also earn bitcoins by participating as a market maker on JoinMarket by allowing users to perform CoinJoin transactions with your bitcoins for a small fee (requires you to already have some bitcoins)
The following is a short list of ongoing projects that might be worth taking a look at if you are interested in current development in the bitcoin space.
One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
1,000 per bitcoin
SI unit for milli i.e. millilitre (mL) or millimetre (mm)
1,000,000 per bitcoin
SI unit for micro i.e microlitre (μL) or micrometre (μm)
1,000,000 per bitcoin
Colloquial "slang" term for microbitcoin
100,000,000 per bitcoin
Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:
