What is Segwit?
SegWit is short for segregated witnesses and it is a proposal presented by the Bitcoin Core team. It comes in the form of a soft fork, a forward compatible upgrade that can work even if some users don’t update their software (without resulting in a chain split). It was released on the 0.13.1 version of Bitcoin Core client. In transactions there are three key elements. The sender, receiver and the signatures (commonly referred to as witnesses) and these make up a big part of the transaction size.
Segwit updates the 1MB block size limit into a 4 million unit block weight limit, counting serialized witness data as one unit and core block data as four units, essentially introducing a new transaction format.
