''' Yes, it's open source. It's being promoted as a backbone for the "internet of things" machine economy since it allows for true micropayments (since transaction fees don't exist). In that realm, the name of the game is interoperability - so while another entity certainly could clone it and start their own tangle, that doesn't help their devices communicate with the rest of the devices using IOTA, which is hopefully going to function as a sort of standard (I see no reason why this won't be the case). So we have all these machines constantly making tons and tons of micropayments (they don't even necessarily need to send an IOTA, they can just send data over the Tangle to communicate!) and each one of those transactions scales and strengthens the network by way of verifying 2 previous transactions. So it doesn't make much sense to create a competing tangle. This crypto is much more than a mere store of value :). Very exciting stuff!

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments. It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
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. You can even run a node on a Raspberry Pi.
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 scaling - On chain transaction fees depend on network demand and how much priority you wish to assign to the transaction. Most wallets calculate on chain fees automatically but you can view current fees here and mempool activity here. On chain fees may rise occasionally due to network demand, however instant micropayments that do not require confirmations are happening via the Lightning Network, a second layer scaling solution currently rolling out on the Bitcoin mainnet.
Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
Portable - Bitcoins are digital so they are easier to move than cash or gold. They can even be transported by simply memorizing a string of words for wallet recovery (while cool this method is generally not recommended due to potential for insecure key generation by inexperienced users. Hardware wallets are the preferred method for new users due to ease of use and additional security).
Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage. Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".
Securing your bitcoins
With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, then you will need to create your own wallet and keep it secure. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor, Ledger or ColdCard is recommended. Alternatively there are many software wallet options to choose from here depending on your use case.
If you prefer to let third party "Bitcoin banks" manage your coins, try Gemini 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.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email! 2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".
Where can I spend bitcoins?
Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.
Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out. If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.
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:
one bitcoin is equal to 100 million satoshis
1,000 per bitcoin
used as default unit in recent Electrum wallet releases
1,000,000 per bitcoin
colloquial "slang" term for microbitcoin (μBTC)
100,000,000 per bitcoin
smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

Welcome to the Bitcoin community and the new decentralized economy!
What do you guys think about having a trusted second layer like PayPal or Visa to process micropayments? Will this help or hurt bitcoin? I think many people would still want to be able to dispute payments and those who prefer truly trust less transactions, can pay the fee to use the base layer?
Summary of Tau-Chain Monthly Video Update - July 2020
Karim Agoras Live: Five functionalities complete: 1. Registration 2. Login 3. User Profile Page 4. Calendar 5. Categories List 6. Wallet Screen Payments: Decided that implementing lightning would be too complex. Instead, we decided to implement our own micropayment mechanism using the native BTC multisig addresses. We are going to use the Omni wallet for payments. TML: Continued debugging, getting a TML demo and test cases ready. Hiring: More hiring efforts to increase team size. Timelines: Committing ourselves to a release of Agoras Live and a basic version of discussions in TML in 2020. Umar: Been working on making improvements to the context free grammar parsing. We now are able to add constraints to productions in the grammar, allowing us to recognize grammars that are context sensitive. Developed test cases for that, too. Tomas: Fixed issues in TML and ran several steps in a TML program. Now adding more tests to make sure everything is stable and won’t break. Also been working on a TML tutorial, a recorded script based on the intro to TML which was contained in the TML Playground. Also new features are going to be covered such as arithmetics. Kilian: More outreach & follow-ups to potential partner universities. Positive response by a professor based in Toronto, presented to him our project. Also, response by KULeuven, Belgium, who unfortunately don’t see a good fit in our project. We’ve had one applicant for the IDNI Grant program and currently are evaluating his proposal. Also, we’ve had an applicant from Bangalore, India for the IDNI Ambassador program and we also have been discussing his proposal. Translation Bounties: We’ve had the blog post “The New Tau” translated to Chinese and have been reviewing the translation. We are going to publish the translation on our website and on the Bitcointalk Chinese forum section. Still to be claimed: German translation of “The New Tau”. Done more effort on reach out to potential tribe channels: Research groups, LinkedIn groups, Facebook groups. Most represented keywords: Complex Adaptive Systems, NLP, Computational Linguistics. Usual feedback: Likes but no further interaction. Created an FAQ answering all possible questions surrounding IDNI, Tau & Agoras Idea: Hosting a virtual panel to spread the word about our project among the scientific community, as well as to create some visual content for our community. Two professors are interested in participating, one from Argentina with a focus in semantic parsing, the other one from the University of Washington with a focus on human-computer interaction and social computing. First step: organizing a pre-panel discussion where in 1on1 calls with the professors we get an opinion of them about what we are doing. Andrei: Agoras Live: Implemented mail system so users now get their mails (e.g. registration email). Improved UX together with Mo’az, e.g. user profiles. Token creation for accessing calls to identify and charge users. Customized Jitsi interface to suit our needs: E.g. display of how much time passed in a call and how much it costs. Next up: Further improve UX; make sure everything works as intended. Mo’az: Almost finished the IDNI website. Added two more pages: Events & Bounties in collaboration with Fola & Kilian. Agoras Live: Finetuned all the website’s components in collaboration with Andrei. Juan: Continued working on the payments system for Agoras Live. Had some delays due to the complexity of debugging such applications. Still, we made significant progress and got the funding transactions implemented over the Lightning network through the Omni layer. Spent time analyzing the minimum amount of BTC to pay for the fees associated to the Omni transactions. We aren’t using segregated witness native addresses and instead are using embedded segregated witness. So transaction sizes are enlarged and transaction fees are a bit higher. So there is a bit of finetuning analysis needed in order to enable the multisig address to pay for the closing & refund transactions. So to provide payment channels over the Omni layer, the main remaining technical detail we have to solve at this point is the closing transaction & the refund transaction. Fola: Have been continuing to look for great talent in different areas. Continued working on website with Mo’az and Kilian. Been working on the branding for Tau & Agoras. Been getting external support to make sure the branding for Tau & Agoras will be as professional as it can be. Working on marketing efforts needed for the release of Agoras Live to get the media pack for marketing ready. Working together with external people to put a plan together for listing the Agoras token on more prominent exchanges as we get closer to release of Agoras Live. Ohad: Continued working on restricted versions of second-order logic to understand how to implement them. There is a translation in the literature about how to convert second-order logic by Horn into Datalog. Also, I have been revisiting papers that deal with descriptive complexity of higher-order logic. They mention that they have a translation from second-order logic to QBF. I wasn’t able to find where they explain this translation but I wrote one of them and he said he will send me the paper. If so, that will be very good because we already have a QBF solver. Any binary decision diagram is already a QBF solver, so we can just translate arbitrary second-order logic formulas into QBF. This will be very helpful for us to implement second-order logic. Also, those papers mention several aspects that are relevant for self-interpretation, the laws of laws. Apparently, they suggest that certain fragments of higher-order logic may also support the laws of laws. But this is part of the papers that I didn’t have access to, so I have to wait to get further clarification. I also pushed the whitepaper significantly this month and hope we will be finishing it soon. Also, I was thinking about some optimizations for the parser and also was looking into the Lightning network. It was my mistake that I haven’t done so beforehand and if I had done it beforehand, I would have understood earlier, that Lightning is too much. It is too drastic of a change to how traditional payments work and there apparently is no reason to believe that it is secure. So I’m glad I discovered better now than later that it’s not something we’d like to rely on, although we can have it as an optional feature. Q&A: Q: With the project development taking longer than other projects such as Tezos, when can AGRS holders expect something to be released and, how can you reassure us that we made the right decision? A: With regards to when we see some releases, it seems that we will see some releases in 2020. For comparing to Ethereum and Tezos: Let’s first talk about funding. Both projects had a lot of money. For Ethereum, the reason for is that it has probably done one of the most aggressive marketing campaigns in history. It was completely lacking any kind of honesty. It was simply aggressive. None of Ethereum’s visions and promises became true. It simply became an insecure platform for scams. None of their vision of creating a world computer, of creating a better society, a better currency, became true. Because of this aggressive marketing, they not only raised a lot of money, they also took the price to be so high in the market. If you remember the campaign of the flipping, they did a whole campaign on how they would overtake the marketcap of Bitcoin. For Tezos, they made maybe the largest ICO in history in terms of money, mainly because they came at the right time, at the top of the bubble in 2017, and also their promises for better coordination didn’t come true. Their solution is based on voting and based on Turing completeness and the only reason why they managed to gain such a market cap as of today, is not because they offer better currency, better society, better anything. It basically is a Ponzi-scheme because they offer very high interest rate by very high inflation (5,51%). The only reason why people buy Tezos is to get into this Ponzi-scheme. Because both Tezos and Ethereum lack any true economical or technological substance, their value will not sustain and this is true for almost all projects in the cryptocurrency world. In the software, high-tech market, if you come up with good tech and you do all the right things, you succeed big time. But if you don’t have it and you are purely relying on brainwashing people, it will not sustain. Of course, our solution is so disruptive and sustainable. We offer to do advancements for humanity and for economy. Q: What three subjects would you first like to see discussed on Tau? A: Of course, picking three subjects now is a bit speculative, but the first thing that comes to mind is the definitions of what good and bad means and what better and worse means. The second subject is the governance model over Tau. The third one is the specification of Tau itself and how to make it grow and evolve even more to suit wider audiences. The whole point of Tau is people collaborating in order to define Tau itself and to improve it over time, so it will improve up to infinity. This is the main thing, especially initially, that the Tau developers (or rather users) advance the platform more and more. Q: What is stopping programmers using TML right now? If nothing, what is your opinion on why they aren’t? A: There is nothing essentially missing in TML in order to let it release. And in fact, we are now working towards packaging it and bringing it towards a release level. For things like documentation, bug fixes, minor features, minor optimizations. We indeed actively work towards releasing TML 1.0 and then we can publish it in e.g. developers channels for them to use it.

The IOTA/Tangle community seems to be the least focused on tokenization. Here's why that's wrong: IOTA may be feeless, but it's not free to use. Users are paying in:
IOTA Volatility (regularly >1% daily)
Exchange fees - moving in/out of IOTA to avoid volatility (0.25 - 1%)
Transaction fees, volatility or exchange fees. Value is lost, it doesn't matter how. "but IOTA will stabilize as it grows" Yes it will, but too slowly for it to matter. Bitcoin isn't stable now at $100 billion, nor was it stable at $300 billion. IOTA won't be either. (IOTA would grow 250-750x in value to reach those market caps. Of course there will be enormous volatility on the way up) Maybe they will be stable enough to use as a medium of exchange (MoE) if they ever reach $trillions. What the Tangle needs most is a stablecoin. Picture this combination:
Ethereum tokens (ERC20/721) - programmable, standardized, plug and play.
Colored coins - every token unit is created 'from' IOTA
Ethereum DAI is supposed to be divisible to 18 decimal places - but gas fees stop you at 2 ($0.01) Tangle DAI (TAI) could be truly divisible, with each unit created from 1i: $1 to $0.01 = 100i ($1 million = 100Mi) $1 to $0.0001 = 10Ki ($1 million = 10Gi) etc This allows for stable micropayments, 100 - 10,000x smaller than what is currently possible. Important points:
TAI would remove the need to ever 'exit' the Tangleconomy.
TAI could be pegged to any single/basket of assets, not just fiat.
TAI Stabilization > DAI's, because of feeless/granular arbitrage. (peg could be $0.99999X, instead of $0.999X)
TAI could have different levels of divisibility ($0.01, $0.0001, etc)
TAI drives IOTA value, making the latter more desirable as a MoE as they both grow.
TAI would accelerate the growth of the Tangle - look at everything that has grown around DAI on Ethereum.
TAI > IOTA for large/normal/micro payments. (volatility is a nonstarter)
IOTA > TAI for nano payments ($0.00001>), unless supply is drastically increased.
This has a couple of effects:
Short/medium term, it removes most of the need for IOTA as an MoE.
IOTA supply will need to be carefully considered/eventually increased. (At $0.10Mi - 1i costs $0.0000001. At $100Mi - 1i costs $0.0001)
Long term, if IOTA grows from billions to trillions, it could become THE medium of exchange.
Debunked: "We need second layers like the Lightning Network in order to enable micropayments"
Satoshi: While I don't think Bitcoin is practical for smaller micropayments right now, it will eventually be as storage and bandwidth costs continue to fall. If Bitcoin catches on on a big scale, it may already be the case by that time. Another way they can become more practical is if I implement client-only mode and the number of network nodes consolidates into a smaller number of professional server farms. Whatever size micropayments you need will eventually be practical.
I've developed a new open source P2P e-cash system called Bitcoin. It's completely decentralized, with no central server or trusted parties, because everything is based on crypto proof instead of trust. Give it a try, or take a look at the screenshots and design paper: Download Bitcoin v0.1 at http://www.bitcoin.org The root problem with conventional currency is all the trust that's required to make it work. The central bank must be trusted not to debase the currency, but the history of fiat currencies is full of breaches of that trust. Banks must be trusted to hold our money and transfer it electronically, but they lend it out in waves of credit bubbles with barely a fraction in reserve. We have to trust them with our privacy, trust them not to let identity thieves drain our accounts. Their massive overhead costs make micropayments impossible. A generation ago, multi-user time-sharing computer systems had a similar problem. Before strong encryption, users had to rely on password protection to secure their files, placing trust in the system administrator to keep their information private. Privacy could always be overridden by the admin based on his judgment call weighing the principle of privacy against other concerns, or at the behest of his superiors. Then strong encryption became available to the masses, and trust was no longer required. Data could be secured in a way that was physically impossible for others to access, no matter for what reason, no matter how good the excuse, no matter what. It's time we had the same thing for money. With e-currency based on cryptographic proof, without the need to trust a third party middleman, money can be secure and transactions effortless. One of the fundamental building blocks for such a system is digital signatures. A digital coin contains the public key of its owner. To transfer it, the owner signs the coin together with the public key of the next owner. Anyone can check the signatures to verify the chain of ownership. It works well to secure ownership, but leaves one big problem unsolved: double-spending. Any owner could try to re-spend an already spent coin by signing it again to another owner. The usual solution is for a trusted company with a central database to check for double-spending, but that just gets back to the trust model. In its central position, the company can override the users, and the fees needed to support the company make micropayments impractical. Bitcoin's solution is to use a peer-to-peer network to check for double-spending. In a nutshell, the network works like a distributed timestamp server, stamping the first transaction to spend a coin. It takes advantage of the nature of information being easy to spread but hard to stifle. For details on how it works, see the design paper at http://www.bitcoin.org/bitcoin.pdf The result is a distributed system with no single point of failure. Users hold the crypto keys to their own money and transact directly with each other, with the help of the P2P network to check for double-spending. Satoshi Nakamoto
FLETA is a blockchain platform for decentralized applications aimed at solving some of the blockchain’s biggest hurdles. They have made advances to solve the scalability issues, but still keeping the blockchain fast and decentralized through a unique consensus algorithm known as Proof-of-Formulation. Formulators are the key to FLETA’s technology. They are the block generators who mine and create new blocks. The mining process is configured in such a fair way that every formulator will get a chance to generate a block. This prevents conflicts and abuse because every miner is equal. Generated blocks are confirmed and signed in real-time by Observer Nodes. They are responsible for securing the network, preventing DDOS attacks, and making forks impossible. Forks cannot happen on FLETA because 3 out of 5 Observers are required to sign and confirm the block. The first block with 3 signatures is the only valid one. Proof-of-Formulation has been tested and verified in real-life scenarios. It is capable of achieving 14,000 transactions but remains highly secure due to the exclusive connection between Formulators and node Observers.
The Matic Network hopes to improve the scalability of Ethereum, by using PoS side chains, but without losing the critical elements of decentralization. Matic’s multiple side chains possibly scale to millions of transactions each second in the future. The transaction fees are inexpensive, and its Plasma framework results in new blocks being generated in less than 2 seconds. It makes Matic a well-suited platform for micropayments. FLETA is using Matic’s Plasma framework solutions on its Mainnet. FLETA has an auto-swap feature between the FLETA ERC-20 token and its native FLETA coin. The two projects have cooperated to improve the Deposit & Withdrawal options on FLETA and making them more decentralized.
TomoChain is a blockchain platform that uses a Proof-of-Stake Voting Consensus to combat scalability. It is based on a network of 150 Masternodes. This technology allows a network throughput of 2,000 transactions per second and a 2 seconds blocktime. TomoChain can be used by developers to build their own DApps. Also, by taking advantage of the TomoX Protocol, they can launch a decentralized exchange. The TomoP Protocol is a privacy feature allowing anonymous transactions. When enabled, it conceals information about the transacting parties, used addresses, and transaction amounts. FLETA and TomoChain have signed a technical agreement that foresees the use of the TomoZ Protocol that allows fees to be paid with different tokens. FLETA will be creating a FLETA Token that can provide broader use cases within the TomoChain ecosystem.
Neo is an open-source blockchain platform that uses smart contracts to digitize assets. The ownership of physical items from the real world can be registered, traded, and transferred via the Neo blockchain. Neo is a strong development platform that supports multiple coding languages and has an experienced development community. FLETA and Neo have signed a strategic partnership, which entails the use of NeoVM on FLETA’s Mainnet. NeoVM is a lightweight and scalable virtual machine for smart-contract development. With its cross-platform compatibility, FLETA will significantly benefit from it. Once deployed, FLETA and Neo will cooperate on several projects. The first planned one is a blockchain-based Real World Data-based Clinical Research Data Registry Platform for the medical industry. The project aims to activate medical data research and help researchers efficiently use the data.
Wanchain is a cross-chain compatible infrastructure that seeks to connect the world of decentralized finance into one interoperable ecosystem. Different blockchain systems are incompatible with each other, and they operate on their own. The answer to this is creating wrapped tokens of the original assets and incorporating them on the Wanchain platform. It allows the coins to be used in ways that weren’t possible before. For example, a wrapped Bitcoin token can be used in an Ethereum smart contract to take advantage of the Ethereum blockchain. The token can be easily exchanged back to real Bitcoin by using Wanchain technology. Wanchain is based on the codebase of Ethereum, but it uses a PoS consensus algorithm. The project has established a partnership with FLETA. With this understanding, both companies expect further to improve interoperability and the performance of their systems.
WINk is a gaming platform offering Live Casino Games, virtual sports, Slots, and E-gaming. WINk was previously known as TronBet, and it is located on the TRON Mainnet. The platform supports several different tokens: TRX, Dice, USDT, BTT, and of course, WIN token. Besides being a gaming community, WINk also features a staking option. By staking WIN tokens, users get the chance to earn daily staking rewards from the platform’s profits. WINk plans to integrate with Wallet Street, the social data platform of FLETA. Wallet Street allows stakeholders to communicate and create online communities. The two platforms will start a joint marketing campaign. Wallet Street allows its users to build their own buildings based on the number of coins they own. These structures become visible on a virtual map on Wallet Street. A WINk building will be constructed on Wallet Street’s map to advertise WINk project and its token.
Cooperation is essential for the crypto industry as it opens new possibilities. The sharing of information and knowledge is beneficial to success. Entering new markets allows companies to expand their user base. A broader reach increases use cases for blockchain technology and achieve the ultimate goal: massive adoption. FLETA has realized the importance of strong partnerships, and during 2020, their services will be taken to a whole new stage.
An Insight Into Bitcoin Improvement Proposal (BIP)
While Bitcoin is the most famous and valuable cryptocurrency, its blockchain faces some challenges. In order to ensure the constant dominance of the currency in the market, the Bitcoin Improvement Proposal (BIP) was introduced. While most BIPs have different levels of potential for positive impact on Bitcoin blockchain, some of them turned out to be much more successful than others.
What is BIP?
Bitcoin is considered the first cryptocurrency and still remains the most successful crypto-project, but it also has its drawbacks. And in order to surpass it, as well as to occupy its niche in the digital world, innovators have created many new currencies, each of which has its own blockchain, designed to provide functions that are not available in Bitcoin. Eventually, one of these new currencies could potentially knock Bitcoin out of the first place. That’s why the work on the Bitcoin Improvement Proposal began. BIP is a document where developers can submit a recommendation to fix a network problem. For example, after the introduction and implementation of BIP 141, also known as Segregated Witness (SegWit), the transaction rate on the Bitcoin network has increased, and commission fees have significantly decreased. There are three varieties of BIP:
Standards Track — these are the changes in the network protocol, checking blocks or transactions, as well as anything that can affect compatibility;
Informational — design issues, general suggestions;
Process — ideas that relate to processing outside the network.
Bitcoin Lightning Network
The Lightning Network is a BIP proposal introduced in 2015 by Joseph Poon and Thaddeus Dryja. It aims to make Bitcoin scalable with the help of instant payments that are performed outside the network. These external channels form real Bitcoin transactions with the use of standard scripts that allow transferring funds without risk. The Lightning network came into force thanks to the introduction of wallets with many signatures, where the parties can conduct an infinite number of transactions without having to store all the details on the blockchain. The only information recorded on the blockchain is the number of Bitcoins contained in the wallet and the percentage of contributions of the parties involved. In addition to enabling instant transactions, the update also provides other benefits for the Bitcoin chain. For example, registration for micropayments, as well as cross-chain payments. Moreover, the update also promotes the implementation of the functionality of smart contracts on top of the blockchain.
MAST stands for Merkelized Abstract Syntax Tree, a technology that uses the ideas of the Merkle tree and the abstract syntax tree. This is a cryptographic tool that allows you to add large volumes of the hash to the data associated with transactions in the Bitcoin chain, due to their layout. Three BIPs aim to introduce MAST into the Bitcoin network. The first is BIP 114, created by Johnson Lau, the developer of the Bitcoin core. The proposal shows how to increase network efficiency by introducing a new scenario, which he calls a merkelized scenario. The scenario reduces the need for large amounts of transaction data while maintaining greater privacy. BIP 116 and BIP 117 were proposed by Bitcoin Core developer Mark Friedenbach and are intended to support MAST in a joint implementation. In BIP 116, he outlines the operation code, which allowed validation of the data without revealing the entire set. BIP 117 is called the Tail Call semantics, and in combination with the first, it led to a generalized form of MAST. The difference between the offers of Friedenbach and Lau is that the first supports all the scenarios that are currently used on the Bitcoin network, and the second supports only native SegWit. The introduction of MAST has led to increased privacy, increased transaction speed, and the ability to include complex data sets, such as smart contracts. Besides, MAST allowed the Bitcoin network to process a much larger volume of transactions and, thereby, increased its scalability.
How many BIPs are there?
Since absolutely any developer can submit the idea of improving the network to the community, more than 300 of these ideas have already been accumulated, and not all of them have been and will be implemented in Bitcoin.

So here in this article, I will focus on the last scaling solution i.e SegWit. What is SegWit? SegWit stands for Segregating Witness i.e separating the signatures from the transactions. In this process, certain parts of a transaction are removed, which will free up space so that more transactions can be added to the chain. The idea behind using this method is to overcome the block size limit of blockchain transactions. In simple terms, SegWit changed the way data are stored, therefore helping the Bitcoin network to run faster and more smoothly.
It was suggested as a soft fork change in the transaction format of Bitcoin in the Bitcoin Improvement Proposal number BIP141.
Problem Statement In the Bitcoin platform, Blocks are getting generated every 10 minutes and are constrained to a maximum size of 1 megabyte (MB). As the number of transactions is increasing, more blocks need to be added to the chain. But due to the block size constraint, only a certain number of transactions can be added to a block. The weight of the transactions can cause delays in processing and verifying transactions. Sometimes, it takes hours to confirm a transaction as valid. This can slow down further when the network is busy. The Solution To overcome the block size limit issue and to enhance the transaction speed, the transaction is divided into two segments. Removing the unlocking signature (witness) from the original portion and appending it as a separate structure at the end. The original portion will still have the sender and receiver data, and the new "witness" structure would contain scripts and signatures. The original data segment would be counted normally, but the new "witness" segment becomes one-fourth of its original size.
Digital signature accounts for 65% of the space in a given transaction.
SegWit is backward compatible, which means nodes that are updated with the SegWit Bitcoin protocol can still work with nodes that haven’t been updated. SegWit measures blocks by block weight. The formula used to calculate block weight: (tx size with witness data stripped) * 3 + (tx size) Since segregated witness creates a sidechain where witness data is stored, it prevents transaction IDs from being altered by dishonest users. It also addresses signature malleability, by serializing signatures separately from the rest of the transaction data, so that the transaction ID is no longer malleable. History Pieter Wuille, a bitcoin developer, first proposed the concept of SegWit. On 24 July 2017 as a part of the software upgrade process i.e Bitcoin Improvement Proposal (BIP) 91, the concept of Segregated Witness is activated at block 477,120. Within one week of implementation, the bitcoin price seen a spike of 50%. The transaction usage rate using SegWit further increased from 7% to 10% in the first week of October. As of February 2018, SegWit transactions exceed 30%. However, a group of China-based bitcoin miners were unhappy with the implementation and later forked to created Bitcoin Cash. Lightning Network - Layer 2 solution Lightning Network operates on top of bitcoin and is referred to as a “Layer 2” component. It is an off-chain micropayment system that is designed to enhance the transaction speed in the blockchain network. SegWit acts as a base component for the Lightning Network. By implementing SegWit, the transaction malleability issue can be prevented which will allow this secure payment system to process millions of transactions per second in the Bitcoin network. Advantages of SegWit: · Prevents transaction malleability problem. · Prevents signature malleability problem. · Helps in scaling the bitcoin network. · Increases block size. · Reduced transaction fees. · Acts as a base for the lightning protocol. Conclusion There is no doubt that Bitcoin technology is very revolutionary but like any other technology, it has certain drawbacks as well as challenges. Scaling is one of them which has restricted in large scale applications adopted. It is capable of processing only 7-10 transactions per second on the base layer. Many developers, researchers from the Bitcoin community are working hard to overcome the problem. SegWit along with the Lightning Network together aiming to allow Bitcoin to process millions (or more) transactions per second. But the real scenario will depend on the success of future projects.
