Invalid block 182159

Why it is invalid

rule

p2sh_redeem_script_failure

Core reject

block-script-verify-flag-failed

Core check

ConnectBlock via CheckInputScripts

CI checks

A complete block, or a proof file holding the transaction and the block's ordered txids, with header time at or after 1 April 2012, in which exactly one input spends the named failing_prevout. That input must pass script evaluation without P2SH and fail with it, checked against the authenticated previous transaction.

Incident note: 173928, 173957, 173998 and 174605 - P2SH redeem-script failure (2012)

Each body includes the same 123-byte transaction, 4005d6bea3a93fb72f006d23e2685b85069d270cb57d15f0c057ef2d5e3f78d2, which spends a pay-to-script-hash output funded at canonical 170054, b0539a45de13b3e0403909b8bd1a555b8cbe45fd4e3f3fda76f3a5f52835c29d:1, worth 400000 satoshis. Its scriptSig pushes only the redeem script, a 1-of-1 OP_CHECKMULTISIG. The pre-BIP16 template check hashes that push and compares it, and passes; executing the redeem script finds no signature on the stack and fails. Nodes applying the 1 April 2012 rules rejected these blocks while older nodes accepted them, which is how the same transaction was included by many miners for months. Core today reports block-script-verify-flag-failed (Operation not valid with the current stack size).
