Segregated Witness (SegWit)

A Bitcoin Improvement Proposal (BIP) that aimed to fix transaction malleability on Bitcoin. In the past, when changing the “witness” information (signatures) on blocks, it would change the transaction ID and its subsequent hash; SegWit was aiming to fix this by segregating signature and block content; a side effect of this change was smaller block sizes and the ability to support second layer solutions.
