Union XXX → CometBLS: Aggregated Consensus at Light Speed

GM CT

Every cross-chain message must prove it was agreed upon by the source chain.

But verifying hundreds of validator signatures?
That’s slow, expensive, and bloats data.

@union_build solves this with CometBLS
An aggregated signature scheme built for fast, efficient consensus.

The problem:
• Each validator signs individually
• Verifying all those signatures is heavy for light clients
• Increases latency, storage, and cost

CometBLS fixes it:

X. Validators sign messages independently

X. Their BLS signatures are aggregated into one proof

X. Union verifies the compact proof instead of hundreds

X. Same security, way less overhead

The result:
• Faster message verification
• Lighter proofs for light clients
• Lower gas and cleaner chain state
• Scalable consensus across chains

CometBLS is why Union can verify cross-chain consensus at ZK speed, without slowing down or bulking up.

Union XXX coming soon: The Galois Prover, and how Union proves consensus with zero knowledge.
