In the latest installment of their research series, Chainlink Labs delves into the transition from Vector Oblivious Linear Evaluation (VOLE) to interactive commitments, emphasizing efficiency and reduced computational costs. The blog explains how random VOLE correlations, prepared during a setup phase, facilitate constant round-trip communication and decrease computational expenses during online interactions. The process involves using Oblivious Linear Evaluation (OLE) to generate correlated value tuples for prover and verifier, preserving information hiding and binding properties. The VOLE scheme is extended to support multiple commitments by using a global key across wire values, allowing for efficient batch proofs. The post also describes a packing technique that generates higher-degree VOLE correlations needed for consistency checks, making the scheme more efficient than traditional methods relying on public-key operations. Future discussions will focus on a VOLE implementation grounded in the Learning Parity with Noise (LPN) assumption, aiming to enhance the practical application of these protocols.
