Flags that specify which parts of a transaction are covered by a signature.
Sighash types (e.g., ALL, NONE, SINGLE, and ANYONECANPAY variants) control what a signature commits to, enabling multi-party construction and advanced contracts. Different chains may extend or modify sighash semantics.
"Using SIGHASH_SINGLE|ANYONECANPAY, each participant signs only their own input and one output, making it easier to coordinate complex transactions."
All terms and definitions may update as the Cryptionary improves.
