We provide implementations of cryptographic primitives that help Ethereum and the broader blockchain ecosystem.Past contributions consisted of proto-danksharding, trusted setup ceremony and verkle trie.https://github.com/crate-crypto/go-ipahttps://github.com/crate-crypto/go-kzg-4844https://github.com/crate-crypto/ceremony-specshttps://github.com/ethereum/kzg-ceremony-sequencer
https://github.com/crate-crypto/go-kzg-4844 (4844) and https://github.com/crate-crypto/go-ipa (verkle tries) are both projects which will impact the OP stack.The OP stack also has shown interest in using zero knowledge proofs -- the cryptographic implementations being implemented in crate-crypto are focussed around this domain.
