Profiling allocations during an initial chain sync shows that a large portion of the allocations due to the CHECKMULTISIG opcode are the result of generating the list of public keys and signatures. This eliminates those allocations as follows: - Use slices into fixed-size stack-based backing arrays for the typical number of public keys and signatures - Make the slice of signature info contiguous instead of pointers which not only eliminates the associated allocations, but also provides better cache locality |

txscript
Package txscript implements the Decred transaction script language. There is a comprehensive test suite.
This package has intentionally been designed so it can be used as a standalone package for any projects needing to use or validate Decred transaction scripts.
Decred Scripts
Decred provides a stack-based, FORTH-like language for the scripts in the Decred transactions. This language is not Turing complete although it is still fairly powerful.
Installation and Updating
This package is part of the github.com/decred/dcrd/txscript/v3 module. Use
the standard go tooling for working with modules to incorporate it.
Examples
- Counting Opcodes in Scripts Demonstrates creating a script tokenizer instance and using it to count the number of opcodes a script contains.
