Optimization Techniques for Efficient Verification

Caching Checkpoints for Faster Proof Verification

Verifying every committee transition from a trusted checkpoint to a required block is computationally expensive. To optimize this process, colibri.stateless can cache intermediate checkpoints, reducing the length of proof chains. This allows:

• Reduced Verification Overhead—Instead of revalidating all sync committee transitions, the client can jump between cached checkpoints.

• Adaptive Checkpoint Selection—The caching strategy dynamically adjusts based on the frequency of requested data.

• Application-Specific Checkpointing—Trusted checkpoints can be provided by an external application or selected based on prior validation history.

To overcome these limitations, an advanced solution involves using zero-knowledge proofs (ZK-proofs). ZK-proofs enable efficient validation of multiple transitions in a single proof, eliminating the need to store intermediate checkpoints while maintaining full verification capabilities.
