Jack Grigg 1b30e57bde ZIP 244: Commit to scriptPubKey in txin_sig_digest instead of scriptCode 
This is a no-op for every scriptPubKey format except P2SH, where we now
commit to the digest of the redeemScript instead instead of redeemScript
directly.

Jack Grigg 68b6147c02 ZIP 244: Reverse order of value and script_code in txin_sig_digest 
This matches the order in which they are committed to in BIP 341 (and
also at the transaction level in S.2).
 2022-01-04 00:52:07 +00:00
Jack Grigg 89f46c2d99 ZIP 244: Add hash_type to the S.2 digest input 
This was committed to by the ZIP 143 and ZIP 243 transaction digest
algorithms, but had been accidentally omitted from ZIP 244. It is not a
security issue because the encoding of each layer uses sentinel values,
meaning we were indirectly committing to hash_type (unlike BIP 341, which
conditionally omits commitments based on hash_type and therefore needs to
directly commit to it). But not committing directly to hash_type would
complicate security analysis of the digest, and including it keeps the
transparent part of ZIP 244 closer to BIP 341.

We additionally import two new consensus rules from BIP 341 that apply
to hash_type.
