Segregated Witness

This page is a stub. Help by expanding it.

Segregated Witness (aka "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 not required to determine transaction effects. In particular, scripts and signatures are moved into this new structure.
