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

Check out examples_test.go for an example of how to use this library.

Benchmarks

To run the benchmarks, execute the following command:

$ go test -bench=.

Consensus specs

This version of the code is conformant with the consensus-specs as of the 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 needs to be 1.18 or above. Since Golang only back ports security fixes to the latest version and one version behind latest, this library will at most be one version behind latest.

Tests are ran against the 1.18, the current version and the latest version. If support for 1.18 is broken, we will update the CI to reflect this with a given reason.
