Перевод был произведен супер быстро! А если добавите еще Сбербанк, чтобы комиссия поменьше, лучшего о не пожелаешь! Так держать!

Выводил эксмо рубли на тинькофф - процедура заняла порядка 5 минут, с 25тыс заплатил комиссию 7,5 рублей.

Результатом доволен на все 146%

Segregated Witness abbreviated as SegWit is an implemented protocol upgrade intended to provide protection from transaction malleability and increase block capacity. SegWit defines a new structure called a witness that is committed to blocks separately from the transaction merkle tree. This structure contains data required to check transaction validity but is not required to determine transaction effects. In particular, signatures and redeem scripts are moved into this new structure, which does not count towards the traditional 1 MB block size limit. Instead, a new weight parameter is defined, and blocks are allowed to have at most 4 million weight units WU. A byte in the original 1 MB zone of the block weighs 4 WU, but a byte in a witness structure only weighs 1 WU, allowing blocks that are technically larger than 1 MB without a hardforking change. Because the witness structure contains Script versioning, it is also possible to make changes to or introduce new opcodes to SegWit scripts that would have originally required a hardfork to function without SegWit. Segregated Witness, or SegWit, is the name used for an implemented soft fork change in the transaction format of the cryptocurrency Bitcoin , which has also been implemented on currencies such as Litecoin , DigiByte and Vertcoin. SegWit is a softphone offered by the Bitcoin Core advancement group. The motivation behind this proposition is to streamline the piece measure, which later on will illuminate the issues of adaptability of the bitcoin organize, square flood, exchange speed, and lessening of commissions. In straightforward words, SegWit enables you to build the proficiency of the square without expanding the piece estimate. Bitcoin is a cryptocurrency , a form of money using cryptography to keep transactions secure. Each record of a unit of Bitcoins is called a 'block', and all blocks are tied together sequentially by using a cryptographic hash on the previous block and storing in the next. This forms a chain of blocks, or a blockchain. Each block of bitcoins contains information about who sends and receives a given unit of bitcoin a transaction , as well as the signature that approves each transaction. Originally, there was no limit to the size of these blocks. But this meant that malicious people could make up fake 'block' data that was very long as a form of Denial of Service DoS attack. Their fake blocks would be detected, but doing so would take a very long time, slowing down the whole system. The solution Satoshi designed was to put a limit on block size, which was 1 MB. This way, attacks using huge blocks would be instantly detected and rejected, without significantly slowing down the network. As Bitcoin has become more popular, the limit began to slow down transactions. A block is added to the chain every ten minutes. With a limit on its size, only so many transactions can be added, as many as fit in a block. Globally, bitcoin cannot currently support transactions with anything like the speed of other currencies or credit cards. It sometimes takes hours to confirm a transaction. Some sites work around this problem, by conducting 'off-chain payments', conducting transactions without waiting for confirmation by the blockchain. Likewise, there are a number of other, unrelated problems that have arisen with the bitcoin protocol. The most important is 'transaction malleability'. This means that several different ways of losing or stealing bitcoins are possible. While a number of different fixes have made this unlikely to happen, the flaw still exists. SegWit proposes significant backward compatibility. It hides its increased block size by changing the definition of a block to be measured as one million 'units' instead of bytes. The 'witness' signature data would be separated from the Merkle tree record of who is sending or receiving the bitcoin. The 'witness' data is moved to the end, and each byte of it would only count as one quarter of a 'unit'. The overall effect would be changing the average block size to about 1. It also addresses signature malleability, by moving signatures out of the transaction data, making them impossible to change. The transaction ID is no longer malleable. This makes bitcoin safer to use with Lightning Network , a way to speed up small payments by bundling them and only writing to the blockchain at the beginning and end of their execution, which would be slightly risky while the malleability problem still exists. Segregated Witness was activated on August 24, Nonetheless, most Bitcoin network transactions have not begun to use the upgrade. On November 8, , the developers of segwit 2x announced that the hard fork planned for around November 16, was canceled due to a lack of consensus. Initially, most bitcoin transactions have not been able to use the upgrade. Softfork — changing the rules by which the unit passes validation verification for authenticity in the blockroom. SoftPhock assumes changes in the code that do not affect the core of the software. Unlike softfork, hardcore 'hard fork' is a more radical and quick solution, which at the same time can endanger the entire bitcoin protocol if any mistake is made during its implementation. For example, the Bitcoin Unlimited solution offered by the developers is a bit of bitcoin. This allows the main unit to accommodate more transactions, and also eliminates the variability of the identifier of the same transaction. Any network node can modify the transaction and broadcast it to the rest. If the modified transaction is included in the block of the primary branch before the original one or later on in a long branch, then the original transaction will be rejected, as it will refer to the used output the same will be rejected and referenced to it. This creates many problems, so how some systems checked the fact of payment by ID. First of all, Segregated Witness solves the problem of scalability of the bitcoin network. The solution will optimize the structure of the transaction block since it allows you to separate transaction signatures from the transfer process. As a result, transactions will take up less space, and the blocks, respectively, will become more spacious. Activation of SegWit also eliminates the problem of the plasticity of transactions, creating conditions for increasing the speed of their confirmation including through the link Segregated Witness with another solution called Lightning Network.
