From bc60b2b4b401f0adff5b8b9678903ff8feb5867b Mon Sep 17 00:00:00 2001 From: Peter Todd Date: Mon, 29 Sep 2014 03:44:25 -0400 Subject: Replace NOP2 with CHECKLOCKTIMEVERIFY (BIP65) CHECKLOCKTIMEVERIFY -> Fails if tx.nLockTime < nLockTime, allowing the funds in a txout to be locked until some block height or block time in the future is reached. Only the logic and unittests are implemented; this commit does not have any actual soft-fork logic in it. Thanks to Pieter Wuille for rebase. Credit goes to Gregory Maxwell for the suggestion of comparing the argument against the transaction nLockTime rather than the current time/blockheight directly. --- src/script/interpreter.h | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'src/script/interpreter.h') diff --git a/src/script/interpreter.h b/src/script/interpreter.h index fc64438f6..35d572f0a 100644 --- a/src/script/interpreter.h +++ b/src/script/interpreter.h @@ -76,6 +76,11 @@ enum // (softfork safe, BIP62 rule 6) // Note: CLEANSTACK should never be used without P2SH.
