cgo-kzg-4844
This package implements Go bindings (using Cgo) for the exported functions in C-KZG-4844.
Installation
go get github.com/ethereum/c-kzg-4844
Go version
This package requires 1.19rc1
or later. Version 1.19beta1
and before will
not work. These versions have a linking issue and are unable to see blst
functions.
Example
For reference, see the example
module in this directory. You can test it out with go run
:
user@system ~/c-kzg-4844/bindings/go/example $ go run .
go: downloading github.com/ethereum/c-kzg-4844 v0.0.0-20230321204456-577d146c0a5a

Tests
Run the tests with this command:
go test
Benchmarks
Run the benchmarks with this command:
go test -bench=Benchmark
Minimal
By default, FIELD_ELEMENTS_PER_BLOB
will be 4096 (mainnet), but you can
manually set it to 4 (minimal), like so:
CGO_CFLAGS="-DFIELD_ELEMENTS_PER_BLOB=4" go build
Note
The go.mod
and go.sum
files are in the project's root directory because the
bindings need access to the c-kzg-4844 source, but Go cannot reference files
outside its module/package. The best way to deal with this is to make the whole
project available, that way everything is accessible.
