Segregation Witness SegWit---Segregated Witness, first presented by Pieter Wuille at the Hong Kong Expansion Conference on December 6, 2015, was officially activated on August 24, 2017 at Block Height 481824 after several years of controversy. So how exactly does isolation witness work? Why can I alleviate the expansion problem? This issue will take you into the second chapter of the expansion of capacity--- isolated testimony.
Segregated Witness (SegWit) is a technical attempt to speed up system transactions without increasing block capacity, and is designed as follows.
The goal of SegWit2x is SegWit + 2MB block expansion. This means that the adoption of SegWit2x means (almost) ensure the activation of Bitcoin Segregated Witness
Segregated Witness can separate the signature transaction from the TXID calculation, and replace the TXID with a cryptographic hash that cannot be extended for the signature transaction. This cryptographic hash will be used as a pointer to only the signed transaction, and the signed transaction is stored in another data structure
The Lightning Network white paper was released in February 2015, and the Segwit solution was proposed in December 2015. Since then, Gregory Maxwell wrote the Lightning Network into the Bitcoin roadmap, forming a "Segregated Witness + Lightning Network" technical route

The cryptocurrencies industry is also well aware of the problem and is taking a number of steps to speed up transactions, including Lightning Network, which makes encrypted payments faster and cheaper by eliminating records of each transaction on the blockchain, while another technology, called Segregated Witness or SegWit, is also working to speed up transactions.
However, even the current low adoption rate of isolated testimony does not mean that people do not need to promote their popularity. In September 2018, AARON Lasher, BRD's chief strategy officer, and other company executives launched a website called "WhenSegwit" with an open letter to the community. In the letter, they implore businesses and users to prioritize segregated witness services while promoting "100% universality" of segregated witness

BitMEX) uses capacity expansion technology to reduce costs while improving network efficiency. The Segregated Witness, activated in 2017, is an expansion upgrade.
At the beginning, it is naturally ideal for isolating witness. Transactions from these addresses require less data to be included in the chunk, making them cheaper. Some wallets use this new format directly, such as Coinomi and Electrum.
The discussion began in 2017, when BIP 9 was used to activate Segregated Witness, an important part of the bitcoin scalability debate. To prevent miners from digging out invalid blocks and suffering losses, isolation witnesses are activated only when 95% of miners say they are ready.
Over time, more than 19,000 BCH was sent to the nested Segregated Witness address
This improvement is happening all the time, which is why we can "pay the script hash (i.e. P2SH, Pay to script hash)" and have quarantined witness (segregated).

At that time, a short-term consensus was reached that Bitcoin should expand the block to 2MB by adding Segregated Witness, but the good times are not long.
"Segregation Witness" is a concept that is closely related to bitcoin expansion, derived from BIP91 (proposed on July 21, 2017, with plans to upgrade the Bitcoin data block to 2MB in November 2017), in English as Segregated Witness.SegWit.

Owner 26 pays higher fees than previous Bitcoin transactions of similar scale. For example, on May 1, a transfer of US$212 million cost only US$3.93. The huge difference in fees may be attributed to the $212 million transaction that used a Segregated Witness (SegWit) address for transfers
Qtum Electrum synchronously updates electrum-related code and releases v0.18.9.
Notably, of the nine companies that are ready to implement bu scenarios, two also support isolation witness (Electrum and Trezor), and five are ready to activate isolation witness.
