Go-KZG-4844
This library provides the necessary cryptographic functions for EIP-4844. If one is not familiar with EIP-4844, you can think of this library as a KZG library where the polynomial degree is set to 4095 and opening proofs are computed on polynomials in lagrange form (4096 evaluations at 4096'th roots of unity).
Installation
$ go get github.com/crate-crypto/go-kzg-4844
Example

for an example of how to use
this library.
Benchmarks
To run the benchmarks, execute the following command:
$ go test -bench=.

following commit: 017a8495f7671f5fff2075a9bfc9238c1a0982f8
Security
- For security bugs in this library, email kev@the.dev.
- This library uses gnark-crypto for elliptic curve operations. An audit of gnark can be seen here. This library uses a more recent version than the audited version, since that version had a serialization bug. We only rely on gnark-crypto's underlying group operations and pairing code for bls12-381. For code that we do need to use, that has not been audited, we have copied it into this library so that it can be a part of this libraries audit. We have noted in the comments which functions we have done this for.
Panics
Panics can be a DoS vector when running code in a node. This library endeavors
to only panic on startup; only methods which are called when we create the
Context
object should panic.
Minimum Supported Golang Version
Because we use generics, the minimum golang version is 1.18, which seems to be fairly conservative. However, if a lower version is needed, replacing the generics is fairly straightforward.
