| * Enable CHECKLOCKTIMEVERIFY as a standard script verify flagPeter Todd2015-06-221-1/+2
| | | | | | | | | | | | | | Transactions that fail CLTV verification will be rejected from the mempool, making it easy to test the feature. However blocks containing "invalid" CLTV-using transactions will still be accepted; this is *not* the soft-fork required to actually enable CLTV for production use.
| * Replace NOP2 with CHECKLOCKTIMEVERIFY (BIP65)Peter Todd2015-06-215-2/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <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.

* | Make empty byte arrays pass CheckSignatureEncoding()Peter Todd2015-01-091-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | Makes it possible to compactly provide a delibrately invalid signature for use with CHECK(MULTI)SIG. For instance with BIP19 if m != n invalid signatures need to be provided in the scriptSig; prior to this change those invalid signatures would need to be large DER-encoded signatures. Note that we may want to further expand on this change in the future by saying that only OP_0 is a "valid" invalid signature; BIP19 even with this change is inherently malleable as the invalid signatures can be any validly encoded DER signature.

| | | | | | | | | | | | | | | | | | | | | If uint256() constructor takes a string, uint256(0) will become dangerous when uint256 does not take integers anymore (it will go through std::string(const char*) making a NULL string, and the explicit keyword is no help).

This bug can be seen in the RPC decodescript command: $ btc decodescript "" { "asm" : "", "type" : "nonstandard", "p2sh" : "31h1vYVSYuKP6AhS86fbRdMw9XHieotbST" } Correct output: $ btc decodescript "" { "asm" : "", "type" : "nonstandard", "p2sh" : "3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy" }

|\ \ | | | | | | | | | 0391423 Discourage NOPs reserved for soft-fork upgrades (Peter Todd)
| * | Discourage NOPs reserved for soft-fork upgradesPeter Todd2014-11-175-2/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* / script: create sane error return codes for script validation and remove loggingCory Fields2014-11-144-119/+304
|/ | | | | | | | | | | 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!
