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.

No amount of decentralization in Bitcoin’s architecture itself can guarantee this. As many Bitcoiners will point out, free access to the asset requires a vibrant and competitive industry of fiat onramps. The existence of quasi monopolists attempting to build regulatory moats in order to raise barriers to entry threatens this. If acquisition of the asset can only occur in a couple large venues, they are not only susceptible to state action, but also liable to collusively deplatform individuals at will. Imagine what happens to the Venezuelan equivalent of Coinbase during a currency crisis: the government trivially shuts it down to preserve its monetary monopoly.bitcoin stiller lurkmore bitcoin bitcoin раздача Touted mitigations to state censorship of Bitcoin’s broadcast layer include Nick Szabo’s long-range radio proposal as well as Samourai/Gotenna’s SMS and short-range radio mesh proofs of concept. These initiatives, however, are still either in the R%trump2%D phase or the very earliest phases of deployment. At present, individuals in internet-restricted locations have little recourse when faced with such an attack, aside from physically getting their funds out of the country in a hardware or paper wallet. This doesn’t, in my opinion, represent a threat to the network itself: it would take an unbelievable amount of international cooperation among states to regulate Bitcoin in this manner.bitcoin telegram bitcoin значок bitcoin кредит nvidia bitcoin bitcoin crush баланс bitcoin

Nakamoto was responsible for creating the majority of the official bitcoin software and was active in making modifications and posting technical information on the bitcoin forum. There has been much speculation as to the identity of Satoshi Nakamoto with suspects including Dai, Szabo, and Finney – and accompanying denials. The possibility that Satoshi Nakamoto was a computer collective in the European financial sector has also been discussed.Virtual machinebitcoin видеокарта miningpoolhub ethereum bitcoin count cryptocurrency calendar nicehash monero bitcoin block

What numeral is to number, and zero is to the void for mathematics, Bitcoin is to absolute scarcity for money: each is a symbol that allows mankind to apprehend a latent reality (in the case of money, time). More than just a new monetary technology, Bitcoin is an entirely new economic paradigm: an uncompromisable base money protocol for a global, digital, non-state economy. To better understand the profundity of this, we first need to understand the nature of path-dependence.
