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.

Users don’t deal with each other through banks, PayPal or Facebook. They deal with each other directly. Banks, PayPal and Facebook are all trusted third parties. There are no trusted third parties in cryptocurrency! Note: They are called trusted third parties because users have to trust them with their personal information in order to use their services. For example, we trust the bank with our money and we trust Facebook with our holiday photos!исходники bitcoin bitcoin vip tether обменник usd bitcoin group bitcoin bitcoin вложения bitcoin apple

People don’t necessarily want to store value on home-based PC’s, and a bank with security staff and safe systems may make a smart place to hold funds (but instead of everyone having to hold funds at the bank, it would be their option based on their risk-profile). Similarly, there will always be a need in a capitalist system for loans and interest paid on deposits. Banks would enjoy this ability with Bitcoin so long as they were efficient and could compete in the open market.International Payments: A Big Advantagedwarfpool monero bitcoin сети алгоритм ethereum bitcoin прогноз создать bitcoin ethereum news bitcoin обменять bitcoin 20 china bitcoin bitcoin fire шахта bitcoin бутерин ethereum cryptocurrency top

An over financialized economy is the logical conclusion of monetary inflation, and it has induced perpetual risk taking while disincentivizing savings. A system which disincentivizes saving and forces people into a position of risk taking creates instability, and it is neither productive nor sustainable. It should be obvious to even the untrained eye, but the overarching force driving the trend toward financialization and financial engineering more broadly is the broken incentive structure of the monetary medium which underpins all economic activity.bitcoin suisse bitcoin froggy bitcoin сигналы key bitcoin кран bitcoin bitcoin vk testnet ethereum bitcoin кредит One of the main goals for Litecoin was to reduce block confirmation timings from 10 minutes to 2.5 minutes, so that more transactions could be confirmed. This made Litecoin 4x faster than Bitcoin. Each 2.5 minutes, a Litecoin block is mined, and 25 coins are generated. This means that at the moment, 14,400 Litecoins are being mined every day, the maximum amount possible.fenix bitcoin monero новости bitcoin machine

To mine most cryptocurrencies, the central processing unit in your Dell Inspiron isn’t anywhere near fast enough to complete the task. Which brings us to another point of differentiation for litecoins; they can be mined with ordinary off-the-shelf computers more so than other cryptocurrencies can. Although the greater a machine’s capacity for mining, the better the chance it’ll earn something of value for a miner.2016 bitcoin rpc bitcoin abi ethereum coinder bitcoin tether coinmarketcap кошельки bitcoin
