SegWit (short for Segregated Witness) is a protocol upgrade that changes the way data is stored. It was activated on litecoin on May 10, 2017, and on bitcoin on 23 August, 2017.
Developer Pieter Wiulle first presented the idea at the Scaling Bitcoin conference in December 2015.
Many hailed it as a long-awaited solution to bitcoin’s scaling problem. The maximum block size in the main protocol is 1MB, which restricts the number of transactions bitcoin can process to approximately 7 per second. This was going to limit bitcoin’s potential growth, and prevent it from becoming a usable high-volume payment system.
While the upgrade does enable a greater number of transactions in bitcoin’s blocks, SegWit’s initial intention was to fix a bug in the bitcoin code called transaction malleability. This flaw allowed anyone to change small details that modified the transaction id (and the subsequent hash) but not the content. While not a critical problem for bitcoin, it prevented the development of more complex features such as second-layer protocols and smart contracts.
SegWit fixed transaction malleability by removing the signature information (otherwise known as the “witness” information) and storing it outside the base transaction block. With that, signatures and scripts can be changed without affecting the transaction id.
Slimming down
A side benefit that is taking on a much greater importance is that, without the signature information, the transactions weigh much less. This means that more can fit in a block, and bitcoin can process a greater throughput without changing the block size.
SegWit introduced a new concept called “block weight.” This is a mashup of the block size with and without the signature data, and is capped at 4MB, while the block size limit for the base transactions remains at 1MB. This means that the SegWit upgrade is compatible with the previous protocol, and avoids the need for a hard fork.
So, SegWit does not increase the block size limit, but it does enable a greater number of transactions within the 1MB blocks. The 4MB cap includes the segregated witness data, which technically does not form part of the 1MB base transaction block.
Building on top
Another big step forward made possible by SegWit is that it supports the development of second layer protocols, such as the lightning network. The malleability fix made any feature that relied on unconfirmed transactions less risky and easier to design.
The lightning network will further boost bitcoin’s transaction capacity by taking frequent, small transactions off-chain, only settling on the bitcoin blockchain when the users are ready.
SegWit activation also boosted development work on other features such as MAST (which enables more complex bitcoin smart contracts), Schnorr signatures (which would enable another transaction capacity boost) and TumbleBit (an anonymous top-layer network).
Not everyone's happy
Not everyone in the bitcoin community agrees that SegWit is the solution bitcoin has been waiting for. Some believe that it is a case of “kicking the can down the road,” and at best a temporary fix.
Resistance to SegWit was one of the factors behind the development of bitcoin cash, a fork of the bitcoin network which chose to implement a larger block size limit rather than rely on a new transaction structure.
Where are we?
In spite of the obvious advantages, the rollout of the upgrade is moving slowly. At pixel time, 14% of transactions were using the new format (you can follow the progress here).
The main reason is that many wallets have yet to add SegWit support. Some big names such as Trezor, Ledger, Electrum and Kraken have already done so. Coinbase – the largest wallet provider in terms of number of transactions – is working on it, and expects to implement the upgrade in early 2018. And the wallet attached to bitcoin’s most popular full node implementation, Bitcoin Core, is expected to roll out SegWit in the first quarter of 2018.
With the main bitcoin code also making SegWit-friendly adjustments, this could lead to an uptick in both usage and additional functionality experimentation. Bitcoin Core maintains a list on its website of businesses and projects working on SegWit integration – at pixel time, 19 implementations had been deployed, with a further 90 ready to go.
As more wallets embrace the upgrade, the percentage of transactions that use the SegWit structure will increase, and bitcoin fees should drop as blocks contain a greater number of transactions. Furthermore, the development of lightning and similar second layer protocols should get more of a boost, enhancing bitcoin’s scope and potential. This is unlikely to happen overnight – but the change is an important one, and represents a big step forward.

bitcoin wm The contract is very simple; all it is a database inside the Ethereum network that can be added to, but not modified or removed from. Anyone can register a name with some value, and that registration then sticks forever. A more sophisticated name registration contract will also have a 'function clause' allowing other contracts to query it, as well as a mechanism for the 'owner' (ie. the first registerer) of a name to change the data or transfer ownership. One can even add reputation and web-of-trust functionality on top.Incorporated exchange: NoYour or your friend’s account could have been hacked—for example, there could be a denial-of-service attack or identity theft.redex bitcoin Bitcoin is designed as a deflationary currency. This means that the purchasing power of a bitcoin will generally increase over time, as opposed to fiat currencies that are designed to lose value over time. This in turn will make people more willing to hold on to their bitcoins, rather than use them for consumption. This reduction in consumption will probably contribute to a net reduction in pollution. However, this is a speculative argument that hasn't been proven right or wrong.monero cryptonote перспективы bitcoin ava bitcoin кошелек tether эпоха ethereum ethereum blockchain bitcoin 33 flappy bitcoin bitcoin mmm валюта monero количество bitcoin bitcoin fpga wallet tether bitcoin okpay ethereum продам stealer bitcoin Financial applicationsbitcoin мониторинг ethereum заработать amazon bitcoin

A coalition of more than 50% of miner power is able to (at great expense to themselves) rewrite transaction history, so miner decentralization is necessary to keep transactions irreversible. Miners burn a lot of electrical power in the mining process so they must constantly be trading their bitcoin income in order to pay bills. This makes miners utterly dependent on the bitcoin economy at large and therefore gives them a strong incentive to mine valid bitcoin blocks that full nodes will accept as payment.Should You Invest in Cryptocurrency?waves cryptocurrency bitcoin упал keepkey bitcoin ethereum serpent preev bitcoin bitcoin адреса конференция bitcoin roulette bitcoin win bitcoin zcash bitcoin обменник tether торговля bitcoin
