WebNov 14, 2024 · Enhancement: Support all SIGHASH types (previously only SIGHASH_ALL was supported). This can enable specialized Bitcoin transactions involving multiple signers and even limited changes to the transaction after signing. To enable the most dangerous SIGHASH modes, you must change Advanced -> Danger Zone -> Sighash Checks. WebAccording to the sighash type (ALL, NONE, SINGLE, ANYONECANPAY), a transaction digest is generated with a double SHA256 of a serialized subset of the transaction, and the signature is verified against this digest with a given public key. The detailed procedure is described in a Bitcoin Wiki article.
