SCRIPT_ERR_MINIMALIF | An OP_IF/OP_NOTIF argument was not a minimal true/false value. |
SCRIPT_ERR_SIG_NULLFAIL | A failed signature check did not provide an empty signature. |
SCRIPT_ERR_DISCOURAGE_UPGRADABLE_NOPS | The script used an upgradable NOP that policy discourages. |
SCRIPT_ERR_DISCOURAGE_UPGRADABLE_WITNESS_PROGRAM | The script used a witness program version reserved for future upgrades. |
SCRIPT_ERR_DISCOURAGE_UPGRADABLE_TAPROOT_VERSION | The script used a Taproot leaf version reserved for future upgrades. |
SCRIPT_ERR_DISCOURAGE_OP_SUCCESS | The Tapscript used an OP_SUCCESS opcode reserved for future upgrades. |
SCRIPT_ERR_DISCOURAGE_UPGRADABLE_PUBKEYTYPE | The script used a public key type reserved for future upgrades. |
SCRIPT_ERR_WITNESS_PROGRAM_WRONG_LENGTH | The witness program had a length invalid for its version. |
SCRIPT_ERR_WITNESS_PROGRAM_WITNESS_EMPTY | The witness for a witness program was empty. |
SCRIPT_ERR_WITNESS_PROGRAM_MISMATCH | The witness did not match the committed witness program. |
