Verifier-to-Verifier Protocol

Definition ∞ A verifier-to-verifier protocol describes a communication standard or interaction sequence where one cryptographic verifier communicates with another verifier. This setup allows for the chaining or aggregation of proofs, or for distributing verification tasks among multiple entities. It facilitates collaborative or layered verification processes, enhancing the efficiency of complex systems.
Context ∞ In scalable blockchain architectures, particularly those employing recursive zero-knowledge proofs or rollup solutions, verifier-to-verifier protocols are essential for aggregating proofs from multiple transactions or batches. This reduces the on-chain verification cost and improves overall network throughput. Technical discussions in crypto news often mention these protocols in the context of advanced scaling solutions and proof aggregation.
