BTC Understand SegWit
Isolation Witness (SegWit) is a modification to the Bitcoin blockchain. It was proposed by developer Pieter Wuille in 2015 and activated in 2017.
SegWit\'s main function is to separate witness data from the basic block, hence the name \"Isolated Witness\".
This separation is designed to create more space in the block, potentially allowing more transactions to be accommodated without changing the original 1MB block size.

Purpose of SegWit
SegWit was developed to solve two major problems in the Bitcoin network: transaction extensibility and limited scalability.
Trading malleability errors mean that anyone can change transaction data, posing a security risk. SegWit solves this problem by separating witness data from master block data, effectively solving this problem.
In addition, Bitcoin\'s scalability is hindered by its small size of blocks, which limits the number of transactions that can be processed in each block. SegWit solves this problem by providing more free space for transactions in each block, which can enhance the capacity of the network.
How SegWit works
SegWit works by isolating witness data from transaction data and storing it in a separate data structure. When a Bitcoin transaction is broadcast, nodes upgraded to SegWit can verify the transaction without having to download witness data until it is needed later.
This separation is intended to increase the effective block size limit, potentially allowing more transactions to fit into a single block. This may lead to changes in transaction fees and transaction verification speed.
Impact of SegWit
Implementation of SegWit has had an impact on the Bitcoin network. It aims to increase the scalability of the network, potentially allowing more transactions to be processed in each block.
This may lead to changes in transaction times and transaction fees, which may affect the overall user experience. By solving malleability errors, SegWit contributes to network security and to network robustness and reliability.
SegWit as a soft fork
SegWit is a soft fork, which means it is a backward compatible change that will not create a new blockchain. This is important because it aims to ensure that all previous transactions on the Bitcoin network remain valid and that users who have not yet upgraded to SegWit can still participate in the network.
This approach is designed to maintain the continuity of the Bitcoin network while allowing changes and updates.
