What Dr. Wiulle thought of was simple why not add a feature to this sidechain? This feature would include the signature data of all transactions, separating it from the main chain in the process. This feature would be called Segregated Witness aka Segwit. So by removing the signature data from the transactions, it was killing two birds with one stone, the block space got emptier and the transactions became malleable free.
There was one more thing that needed to be worked on, however. Segwit activation was possible only via a hardfork, which is what everyone wanted to avoid. The developers wanted to look at soft fork alternatives. That was when Luke Dashjr hit gold. To utilize segwit as a soft fork the developers had to come up with 2 ingenious innovations.
They are as follows:. The above diagram shows what a Merkle tree looks like. In a Merkle tree, each non-leaf node is the hash of the values of their child nodes. Leaf Node: The leaf nodes are the nodes in the lowest tier of the tree. So wrt the diagram above, the leaf nodes will be L1, L2, L3 and L4.
Child Nodes: For a node, the nodes below its tier which are feeding into it are its child nodes. All the transactions inside a block are arranged in the form of a Merkle tree, and the Merkle root of all that data is kept inside the block. The transactions can all be accessed by traversing through the Merkle root. So, what the segwit developers suggested was, why not run another Merkle tree, but only with the signature data?
That was the first innovation. The second innovation was knowing where exactly to put the Merkle root of the signature data. The developers knew that in order to activate the segwit soft fork, the signature root needed to be placed in the block. The spot that they chose was the coinbase transaction spot. Now remember, we talked about this before, the coinbase transaction is the first transaction that takes place in a block, this basically the transaction that gives miners their reward and had no input value whatsoever.
By putting the signature merkle in a new place in the block, they were increasingly the block size…without actually increasing the block size limit in the first place! So basically what segwit achieved was that they increased the block size AND made the whole transition backwards compatible aka a soft fork! This was a major breakthrough which gave the bitcoin network a temporary fix for their scaling issues. In the Hong Kong convention, Dr Wiulle introduced the Segwit proposal which was largely received very well.
This was supposed to be the answer that everyone was looking for. Some of the miners had a big problem with Segwit. When the developers built SegWit they added a special clause to it. After all, it is a huge change in the system and they figured that getting a super majority was the way to go. However, this caused a disruption in the system.
They were afraid that since the available block space will increase, there will be more space available for transactions and that will reduce the waiting time. So as a result, the implementation of segwit was stalled. This, in turn, infuriated the users. In the context of a blockchain, users are people who run nodes in the blockchain network. They realized that something needed to be done to encourage the miners to mine segwit activated blocks.
The CEO of DCG Barry Silbert believed that the bitcoin community was under a lot of turmoil and, if not addressed, could lead to a lot of tensions in the future. He called in everyone for a truce meeting in New York.
On May 21 , prominent members of the bitcoin community met in New York for the convention. After a lot of deliberations, a compromise was reached between the pro-segwit and the pro-blocksize increase camp. It is basically a 2 stage agreement. There were some very vocal detractors of the segwit2x. In fact, this led on to the series of events which eventually gave birth to bitcoin Cash.
However, a lot of the members in the community decided that this was the best path moving forward for bitcoin. Everyone was very excited about the upcoming segwit activation which was going to be around mid-July. But then something happened, because of a lot of complications, the miners missed the window! Segwit was not activated when it should have and that caused widespread panic because it was felt that this would split the bitcoin Core community even more. This drop in price startled the mining community and sprung them into action.
By 20th July, the first stage of segwit activation, the BIP 91 activation was locked in. By August 8th the point of no return was reached and finally, on August 24th, Segwit got activated. Pros of segwit :. Basically, doubling the amount of transactions in a block will double a number of transactions and that, in turn, will double the amount of signature data that will be inside each of those transactions.
This would make the transactions even bulkier and increase the transaction time by a huge amount. This opens the gates for malicious parties who may want to spam the blockchain. Segwit resolves this by changing the calculation of the signature hash and make the whole process more efficient as a result. The following few months could be the most important and exciting times in bitcoin history since Satoshi Nakamoto first published the Bitcoin white paper.

The solution he found was to encrypt all the witness data of a block on the SegWit sidechain and store this root code on the main blockchain. This allowed Bitcoin SegWit to patch transaction malleability without becoming a hard-fork update. First, let me explain what scalability is. Scalability is the ability of a network to process huge amounts of transactions without transaction speeds going down.
If a network is scalable, it will be able to process transactions as fast, or even faster, as it gets bigger. Unfortunately, most cryptocurrencies process transactions slower the bigger they get. Cryptocurrencies have a scalability problem because transactions are processed by consensus. As I mentioned earlier, more than half the nodes on the Bitcoin network need to agree that a transaction is valid before it can be added to the blockchain.
The more nodes there are on the network, the longer it takes to reach an agreement or consensus. The Bitcoin community has been debating different ways to scale the network for a long time. The problem gets worse as the platform becomes more popular so time is running out to find a solution.
By removing witness data, SegWit Bitcoin blocks now have room for much more transaction information. Each block now has a set block weight which is capped at 4MB. A segregated witness allows the network to process more transactions without changing the overall Bitcoin blockchain size. It makes the network lighter by removing witness data from transactions without affecting the Bitcoin blockchain size.
Now, I want to tell you about another exciting development that SegWit is making possible. What is SegWit being used for now? The lightning network allows users to set up payment channels for micropayments. Jude works for Lucy. She pays him 1BTC per day. Rather than processing the transaction on the main blockchain, Lucy and Jude set up a private payment channel where Lucy can send Bitcoin directly to Jude. She sends him a micropayment of 1BTC per day.
Each micropayment needs to be signed by both Lucy and Jude. They are called multi-signature transactions for this reason. Jude works for Lucy for ten days. At the end of the ten days, Lucy and Jude close the payment channel. At this point, all the micropayments are broadcast to the network as one transaction for 10BTC. Payment channels like these form the basis of a lightning network of thousands of micropayments taking place away from the main blockchain.
Transactions are only added to the main blockchain when users close the payment channel. So, what is SegWit doing to make this possible? Micropayments are unconfirmed transactions that only become valid when the payment channel is closed and the total balance of transactions is processed by the network. Without Bitcoin SegWit, users could alter transaction IDs in multi-signature transactions using transaction malleability.
This would mean chaos for the system and leave it completely unworkable. You now know what SegWit is, how it works and what it means for the Bitcoin network. SegWit is a simple and creative solution to a major problem in the Bitcoin protocol. SegWit makes the Bitcoin blockchain lighter.
It allows more transactions to be processed without increasing the overall Bitcoin blockchain size. Higher transaction speed means lower transaction fees. Bitcoin transaction fees can be incredibly high so any changes that bring them down should be welcomed by the community. If Bitcoin is going to serve a network of millions of people, then it needs to solve the problem of scalability. SegWit helps to make scalability projects like the lightning network a reality.
Other Bitcoin services - like wallets - have also been slow to support the SegWit changes. The numbers have improved since then, but the network is still a long way from being completely updated. They claim that only major changes to the Bitcoin blockchain size and the way transactions are processed will help the platform to scale in the future. The disagreements surrounding SegWit have caused several hard forks.

Learn about the the most secure vaults in the world, and how you can acquire one of such vaults yourself! Learn how to convert Bitcoin to cash on Binance P2P, and start exchanging today! When Pieter Wuille designed SegWit, he wanted to fix the problems that transaction malleability was causing.
But SegWit did much more than that, it created a massive discussion about the future of the Bitcoin platform itself. Bitcoin is nearly ten years old. There are hundreds of new blockchain projects offering some of the most advanced crypto techs ever seen. Some see SegWit Bitcoin as a positive change for the network.
The SegWit debate continues throughout the Bitcoin community, and now you know enough to have your say. What is Segwit to you? Is it an exciting new development that will take Bitcoin into the future? Or is it a temporary solution to the much bigger problems that the Bitcoin network faces? We do not publish biased feedback or spam. So if you want to share your experience, opinion or give advice - the scene is yours! Picking out the best crypto exchange for yourself, you should always focus on maintaining a balance between the essential features that all top crypto exchanges should have, and those that are important to you, personally.
That said, many users believe that Coinbase is one of the simpler exchanges on the current market. The exchange platform i. Binance acts as a middleman - it connects you your offer or request with that other person the seller or the buyer. When considering cryptocurrency exchange rankings, though, both of these types of businesses exchanges and brokerages are usually just thrown under the umbrella term - exchange.
This is done for the sake of simplicity. No, definitely not! While some of the top cryptocurrency exchanges are, indeed, based in the United States i. Coinbase or Kraken , there are other very well-known industry leaders that are located all over the world. While there are many reasons for why an exchange would prefer to be based in one location over another, most of them boil down to business intricacies, and usually have no effect on the user of the platform.
