# nim-eth2-official-tests

This repo used to reformat the official Ethereum 2 tests to a format suitable for [Nimbus](https://github.com/status-im/nimbus)/[nim-beacon-chain](https://github.com/status-im/nim-beacon-chain).

Currently it is used for:

- Having multiple test vectors versions side-by-side for progressive update between spec versions
- SSZ test vectors that are still using a JSON format from 0.8.1.
- SSZ test vectors in JSON that require LFS
