Peter Todd	bc60b2b4b4	Replace NOP2 with CHECKLOCKTIMEVERIFY (BIP65) <nLockTime> CHECKLOCKTIMEVERIFY -> <nLockTime> 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.	10 years ago

Pieter Wuille	98b135f97f	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.	10 years ago
Peter Todd	03914234b3	Discourage NOPs reserved for soft-fork upgrades NOP1 to NOP10 are reserved for future soft-fork upgrades. In the event of an upgrade such NOPs have VERIFY behavior, meaning that if their arguments are not correct the script fails. Discouraging these NOPs by rejecting transactions containing them from the mempool ensures that we'll never accept transactions, nor mine blocks, with scripts that are now invalid according to the majority of hashing power even if we're not yet upgraded. Previously this wasn't an issue as the IsStandard() rules didn't allow upgradable NOPs anyway, but `7f3b4e95` relaxed the IsStandard() rules for P2SH redemptions allowing any redeemScript to be spent. We do* allow upgradable NOPs in scripts so long as they are not executed. This is harmless as there is no opportunity for the script to be invalid post-upgrade.	10 years ago
Cory Fields	ab9edbd6b6	script: create sane error return codes for script validation and remove logging Attempt to codify the possible error statuses associated with script validation. script/types.h has been created with the expectation that it will be part of the public lib interface. The other flag enums will be moved here in a future commit. Logging has also been removed in order to drop the dependency on core.h. It can be re-added to bitcoind as-needed. This makes script verification finally free of application state and boost!	10 years ago
