Ethereum Beacon Chain Light Client SDK in Rust
_{⚠️ Beta Software ⚠️}

The sync-committee-rs is the implementation of the Ethereum beacon light client prover & verifier in Rust. This is based on the research done here: https://research.polytope.technology/ethereum-light-client

This library consists of

• ✅ The primitives.
• ✅ The prover.
• ✅ The verifier

Deprecation

This repo has been moved to the hyperbridge repo

primitives

Consists of the types and structs as defined and described in the spec mentioned earlier. It also consists of the utility functions to be used in the verifier and prover.

prover

Consists of the various proof generations for the ethereum beacon chain structs/types such as:

• Execution payload
• Finalized header
• Block roots
• Sync committee update

verifier

This exports a single function for verifying ethereum's sync committee attestation.

Major Depedencies

The major dependencies for this SDK/Library are:

• ssz-rs
• ethereum-consensus

Running the prover tests

NOTE

1. To run these tests make sure the latest fork version on your devnet is the BELLATRIX_FORK_VERSION as defined in the mainnet config
2. Modify sync_committee_primitives::types::GENESIS_ROOT_VALIDATORS defined under the testing
   feature flag to match the one that is present in the devnet you are running the tests with
3. Make sure the SLOTS_PER_EPOCH is set to 32 in your devnet.
