I'm requesting feedback for Hash Time-Locked Contract (HTLC) transactions
in Bitcoin.
HTLC transactions allow you to pay for the preimage of a hash. CSV/CLTV can
be used to recover your funds if the other party is not cooperative. These
scripts take the following general form:
[HASHOP] <digest> OP_EQUAL
OP_IF
<seller pubkey>
OP_ELSE
<num> [TIMEOUTOP] OP_DROP <buyer pubkey>
OP_ENDIF
OP_CHECKSIG
These transactions are useful for both the Lightning network and in
zero-knowledge contingent payments. This very script (using CLTV and
SHA256) was used as part of our "pay-to-sudoku" ZKCP demo earlier this
year: https://github.com/zcash/pay-to-sudoku
Members of the community have expressed the desire for a BIP to submitted
in coordination with changes to Bitcoin Core that support these
transactions in the wallet.
Please review my draft BIP here:

An implementation is being worked on here:

Thanks!
