Modules

script_pubkey

Helpers for handling scriptPubkeys without allocations

Structs

DefaultCheckTemplateVerifyHash

Default CHECKTEMPLATEVERIFY hash of a transaction

Constants

OP_CHECKTEMPLATEVERIFY

The BIP redefines OP_NOP4 to fail script evaluation if the top element on the stack is 32 bytes long and does not match the default template hash calculated for the current input index. If the top element is not 32 bytes long, this opcode does nothing. In both cases, the stack is not modified. Does nothing.
