* Implement Tapscript script validation rules (BIP 342)Johnson Lau2020-10-121-0/+10
| | | | | | This adds a new `SigVersion::TAPSCRIPT`, makes the necessary interpreter changes to make it implement BIP342, and uses them for leaf version 0xc0 in Taproot script path spends.
* Implement Taproot validation (BIP 341)Pieter Wuille2020-10-121-0/+4
| | | | | | | | | This includes key path spending and script path spending, but not the Tapscript execution implementation (leaf 0xc0 remains unemcumbered in this commit). Includes constants for various aspects of the consensus rules suggested by Jeremy Rubin.
* Support for Schnorr signatures and integration in SignatureCheckers (BIP 340)Pieter Wuille2020-10-121-0/+6
| | | | | | This enables the schnorrsig module in libsecp256k1, adds the relevant types and functions to src/pubkey, as well as in higher-level `SignatureChecker` classes. The (verification side of the) BIP340 test vectors is also added.
* Fix misleading error message: Clean stack rulesanket17292020-09-241-1/+1
| | | | | | | Error messages in cleanstack is misleading as it lets the user believe that there are extra elements on stack which is incorrect if the stack is empty.
* refactor: Replace const char* to std::stringCalvin Kim2020-05-221-1/+3
| | | | | Some functions should be returning std::string instead of const char*. This commit changes that.

* Add constant scriptCode policy in non-segwit scriptsJohnson Lau2018-05-051-0/+4
| | | | This disables OP_CODESEPARATOR in non-segwit scripts (even in an unexecuted branch), and makes a positive FindAndDelete result invalid. This ensures that the scriptCode serialized in SignatureHash() is always the same as the script passing to the EvalScript.

* Replace NOP2 with CHECKLOCKTIMEVERIFY (BIP65)Peter Todd2015-06-211-0/+4
| | | | | | | | | | | | | | | | <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 STRICTENC invalid pubkeys fail the script rather than the opcode.Pieter Wuille2014-11-201-0/+2
| | | | | | | 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.
* Discourage NOPs reserved for soft-fork upgradesPeter Todd2014-11-171-0/+2
| | | | | | | | | | | | | | | | | 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 Fields2014-11-141-0/+67
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!
