It will be `1` if the input script correctly spends the previous output `scriptPubKey`. - -##### Parameters -###### bitcoinconsensus_verify_script -- `const unsigned char *scriptPubKey` - The previous output script that encumbers spending. -- `unsigned int scriptPubKeyLen` - The number of bytes for the `scriptPubKey`. -- `const unsigned char *txTo` - The transaction with the input that is spending the previous output. -- `unsigned int txToLen` - The number of bytes for the `txTo`. -- `unsigned int nIn` - The index of the input in `txTo` that spends the `scriptPubKey`. -- `unsigned int flags` - The script validation flags *(see below)*. -- `bitcoinconsensus_error* err` - Will have the error/success code for the operation *(see below)*. - -###### bitcoinconsensus_verify_script_with_amount -- `const unsigned char *scriptPubKey` - The previous output script that encumbers spending. -- `unsigned int scriptPubKeyLen` - The number of bytes for the `scriptPubKey`. -- `int64_t amount` - The amount spent in the input -- `const unsigned char *txTo` - The transaction with the input that is spending the previous output. -- `unsigned int txToLen` - The number of bytes for the `txTo`. -- `unsigned int nIn` - The index of the input in `txTo` that spends the `scriptPubKey`. -- `unsigned int flags` - The script validation flags *(see below)*. -- `bitcoinconsensus_error* err` - Will have the error/success code for the operation *(see below)*. -

The amount spent in the input -- `const unsigned char *txTo` - The transaction with the input that is spending the previous output. -- `unsigned int txToLen` - The number of bytes for the `txTo`. -- `UTXO *spentOutputs` - Previous outputs spent in the transaction. `UTXO` is a struct composed by `const unsigned char *scriptPubKey`, `unsigned int scriptPubKeySize` (the number of bytes for the `scriptPubKey`) and `unsigned int value`. -- `unsigned int spentOutputsLen` - The number of bytes for the `spentOutputs`. -- `unsigned int nIn` - The index of the input in `txTo` that spends the `scriptPubKey`. -- `unsigned int flags` - The script validation flags *(see below)*. -- `bitcoinconsensus_error* err` - Will have the error/success code for the operation *(see below)*. - -##### Script Flags -- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_NONE` -- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_P2SH` - Evaluate P2SH ([BIP16](https://github.com/bitcoin/bips/blob/master/bip-0016.mediawiki)) subscripts -- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_DERSIG` - Enforce strict DER ([BIP66](https://github.com/bitcoin/bips/blob/master/bip-0066.mediawiki)) compliance -- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_NULLDUMMY` - Enforce NULLDUMMY ([BIP147](https://github.com/bitcoin/bips/blob/master/bip-0147.mediawiki)) -- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_CHECKLOCKTIMEVERIFY` - Enable CHECKLOCKTIMEVERIFY ([BIP65](https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki)) -- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_CHECKSEQUENCEVERIFY` - Enable CHECKSEQUENCEVERIFY ([BIP112](https://github.com/bitcoin/bips/blob/master/bip-0112.mediawiki)) -- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_WITNESS` - Enable WITNESS ([BIP141](https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki)) -- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_TAPROOT` - Enable TAPROOT ([BIP340](https://github.com/bitcoin/bips/blob/master/bip-0340.mediawiki), [BIP341](https://github.com/bitcoin/bips/blob/master/bip-0341.mediawiki), [BIP342](https://github.com/bitcoin/bips/blob/master/bip-0342.mediawiki)) - -##### Errors -- `bitcoinconsensus_ERR_OK` - No errors with input parameters *(see the return value of `bitcoinconsensus_verify_script` for the verification status)* -- `bitcoinconsensus_ERR_TX_INDEX` - An invalid index for `txTo` -- `bitcoinconsensus_ERR_TX_SIZE_MISMATCH` - `txToLen` did not match with the size of `txTo` -- `bitcoinconsensus_ERR_DESERIALIZE` - An error deserializing `txTo` -- `bitcoinconsensus_ERR_AMOUNT_REQUIRED` - Input amount is required if WITNESS is used -- `bitcoinconsensus_ERR_INVALID_FLAGS` - Script verification `flags` are invalid (i.e. not part of the libconsensus interface) -- `bitcoinconsensus_ERR_SPENT_OUTPUTS_REQUIRED` - Spent outputs are required if TAPROOT is used -- `bitcoinconsensus_ERR_SPENT_OUTPUTS_MISMATCH` - Spent outputs size doesn't match tx inputs size - -### Example Implementations -- [NBitcoin](https://github.com/MetacoSA/NBitcoin/blob/5e1055cd7c4186dee4227c344af8892aea54faec/NBitcoin/Script.cs#L979-#L1031) (.NET Bindings) -- [node-libbitcoinconsensus](https://github.com/bitpay/node-libbitcoinconsensus) (Node.js Bindings) -- [java-libbitcoinconsensus](https://github.com/dexX7/java-libbitcoinconsensus) (Java Bindings) -- [bitcoinconsensus-php](https://github.com/Bit-Wasp/bitcoinconsensus-php) (PHP Bindings) -- [rust-bitcoinconsensus](https://github.com/rust-bitcoin/rust-bitcoinconsensus) (Rust Bindings)
