I try to spend a P2SH transaction (in regtest) with a timelockscript of 200 blocks. I got the following error:

mandatory-script-verify-flag-failed (Script failed an OP_EQUALVERIFY operation) (code 16)

Unfortunately I can't find the error, as the script and the sequence seems to be fine.

  • I suspect your transaction 531a114b159908390422e4d56fa23c27b687538b4485677fbe951db75527b73d; could you please edit in its raw hex? – Alistair Mann Feb 6 at 16:00

The failure is happening because hash160(30450221009b813cf658ec2c30e68fd23c369c348fd5f915f77b49581a945aa2f2f2d3c8aa022058f6a7eb78b2132d24cc260699fdc158fda6f3a0d10bc3c52bacccc03bb6b8cb) is not 023fb59ee7e5722a9c559d366f6ca114c73361108c04e27a18060cef7a727d58a9.

Hash160s are 160 bits long, ending up as 40 hex chars. 023fb... above is 66 chars, so no hash160 would match it. Investigate where it's coming from?


I find btcdeb https://github.com/kallewoof/btcdeb incredibly useful for these sorts of problems: it's a command line tool to allow single-stepping of bitcoin scripts. OP's script is: 30450221009b813cf658ec2c30e68fd23c369c348fd5f915f77b49581a945aa... | 02c800b27576a921023fb59ee7e5722a9c559d366f6ca114c73361108c04e27... | <<< scriptPubKey >>> | OP_HASH160 | ef3c5e4ee866b692245de650b178d83ca3d0fdbd | OP_EQUAL | <<< P2SH script >>> | c800 | OP_CHECKSEQUENCEVERIFY | OP_DROP | OP_DUP | OP_HASH160 | 023fb59ee7e5722a9c559d366f6ca114c73361108c04e27a18060cef7a727d58a9 | OP_EQUALVERIFY | OP_CHECKSIG | #0000
