firewood-go-ethhash provides a Golang FFI wrapper for Firewood.
This repo serves serves as a mirror, maintained by Firewood CI, to include both the Firewood Golang FFI source code and attach pre-built binaries directly to source. This enables the Go toolchain to import Firewood and use the pre-built binaries with CGO without worrying about the fact it's implemented in Rust.
These binaries provide an Ethereum-compatible hashing scheme, emulating that of HashDB and PathDB. For example usage, see the Firewood hashing tests.
Although Firewood supports a more efficient version of merkle hashing for general purpose use, this is disabled for these pre-built binaries.
For complete documentation, see Firewood FFI.
