In bitcoin terms, the witness satisfies a cryptographic condition placed on an unspent transaction output (UTXO). In the context of bitcoin, a digital signature is _one type of witness_, but a witness is more broadly any solution that can satisfy the conditions imposed on an UTXO and unlock that UTXO for spending. The term “witness” is a more general term for an “unlocking script” or “scriptSig.”
