What is Consensus verification?
Consensus verification is a process where validators on one blockchain verify that a consensus has been achieved among validators on another blockchain before accepting a transaction or message. This ensures that cross-chain interactions, such as asset transfers or message passing, are secure and trust-minimized.
Unlike traditional bridging protocols that rely on centralized entities or private keys (e.g., Proof of Authority systems like LayerZero or Circle's CCTP), Union's consensus verification leverages the inherent security of the blockchain itself, trusting the chain’s validator set rather than external intermediaries.
Consensus Verification and UNION
Union’s consensus verification process is designed to facilitate interoperability across diverse blockchain ecosystems, including Ethereum, Cosmos, Solana and others through:
• Galois: Union’s ZK consensus proving system, which generates fast, low-cost, and censorship-resistant proofs.
Galois can produce consensus proofs for XXX validators in just X seconds, ensuring quick bridging and a seamless user experience.
• CometBLS: CometBLS, an enhanced consensus engine built and tailored for efficient zero-knowledge proving. CometBLS aggregates signatures using Boneh-Lynn-Shacham (BLS) signatures, which reduce transaction size and on-chain computation costs compared to ECDSA verification. This allows Union to verify consensus efficiently, even on blockspace-constrained chains like Ethereum.
The Union chain acts as an aggregation layer where a decentralized validator set reaches consensus on the relayed block headers. As long as at least one-third plus one of the validators are honest, the network and bridge remain secure.
