From 98b135f97f16005687f420136114f80555bc8688 Mon Sep 17 00:00:00 2001 From: Pieter Wuille Date: Sat, 8 Nov 2014 09:32:29 -0800 Subject: Make STRICTENC invalid pubkeys fail the script rather than the opcode. This turns STRICTENC turn into a softforking-safe change (even though it is not intended as a consensus rule), and as a result guarantee that using it for mempool validation only results in consensus-valid transactions in the mempool. --- src/script/interpreter.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/script/interpreter.h') diff --git a/src/script/interpreter.h b/src/script/interpreter.h index 12b2719414..35b2f6c65a 100644 --- a/src/script/interpreter.h +++ b/src/script/interpreter.h @@ -35,8 +35,8 @@ enum SCRIPT_VERIFY_P2SH = (1U << 0), // Passing a non-strict-DER signature or one with undefined hashtype to a checksig operation causes script failure. - // Passing a pubkey that is not (0x04 + 64 bytes) or (0x02 or 0x03 + 32 bytes) to checksig causes that pubkey to be - // skipped (not softfork safe: this flag can widen the validity of OP_CHECKSIG OP_NOT). + // Evaluating a pubkey that is not (0x04 + 64 bytes) or (0x02 or 0x03 + 32 bytes) by checksig causes script failure. + // (softfork safe, but not used or intended as a consensus rule).
