Here is a short review of previously-proposed and exotic SIGHASH types. SIGHASH_MULTIPLE SIGHASH_LIST: https://bitcointalk.org/index.php?topic=252960.0 https://bitcointalk.org/index.php?topic=212555.0
SIGHASH_MULTIPLE SIGHASH_WITHINPUTVALUE: https://bitcointalk.org/index.php?topic=191003.0 SIGHASH_WITHINPUTVALUE: http://lists.linuxfoundation.org/pipermail/bitcoin-dev/2015-January/007185.html SIGHASH_NOINPUT: https://github.com/Roasbeef/bitcoin/commit/4b3c3f1baf7985208ceb6887261ee150ab6e3328 https://github.com/Roasbeef/btcd/commit/67830e506fa135d5239177340918cea39909e6a4 http://lightning.network/lightning-network-paper.pdf SIGHASH_NORMALIZED SIGHASH_NOINPUT: http://diyhpl.us/wiki/transcripts/sf-bitcoin-meetup/2015-02-23-scaling-bitcoin-to-billions-of-transactions-per-day/ SIGHASH_WITHOUT_PREV_SCRIPTPUBKEY SIGHASH_WITHOUT_PREV_VALUE SIGHASH_WITHOUT_INPUT_TXID SIGHASH_WITHOUT_INPUT_INDEX SIGHASH_WITHOUT_INPUT_SEQUENCE SIGHASH_WITHOUT_OUTPUT_SCRIPTPUBKEY SIGHASH_WITHOUT_OUTPUT_VALUE SIGHASH_WITHOUT_INPUTS SIGHASH_WITHOUT_OUTPUTS SIGHASH_WITHOUT_INPUT_SELF SIGHASH_WITHOUT_OUTPUT_SELF SIGHASH_WITHOUT_TX_VERSION SIGHASH_WITHOUT_TX_LOCKTIME SIGHASH_SIGN_STACK_ELEMENT: https://github.com/scmorse/bitcoin-misc/blob/master/sighash_proposal.md Similarly, petertodd has asked for a SIGHASH_DONT_SIGN_TXID before to make OP_CODESEPARATOR more useful. SIGHASH_DANGEROUSLYPROMISCUOUS: http://gnusha.org/bitcoin-wizards/2015-04-17.log SIGHASH_DOUBLE: 06:41 < lorenzoasr> maybe a SIGHASH_DOUBLE that signs INPUT[i] and OUTPUT[i] and OUTPUT[i+1] could be very helpful Some sighash types briefly proposed by petertodd in #bitcoin-dev: SIGHASH_NLOCKTIMEVERIFY SIGHASH_SUM (for merging multiple payments) And finally one from wumpus (#bitcoin-dev): SIGHASH_UNICORN - Bryan http://heybryan.org/ 1 512 203 0507 _______________________________________________ bitcoin-dev mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
