Segregated Witness (SegWit), formally known as Segregated Witness (Consensus layer), is an implemented soft fork change in the transaction format of bitcoin. SegWit had Bitcoin Improvement Proposal number BIP 141. The declared purpose was to prevent nonintentional bitcoin transaction malleability; allow optional data transmission; and to bypass certain protocol restrictions (such as the block size limit) with a soft fork. Segregated Witness was activated on 24 August 2017. It was also intended to mitigate a blockchain size limitation problem that reduces Bitcoin transaction speed. It does this by splitting the transaction into two segments, removing the unlocking signature ("witness" data) from the original portion and appending it as a separate structure at the end. The original section would continue to hold the sender and receiver data, and the new "witness" structure would contain scripts and signatures. The original data segment would be counted normally, but the "witness" segment would, in effect, be counted as a quarter of its real size.
