An execution trace is a detailed record of all computational steps performed during the operation of a program or smart contract. It documents the sequence of instructions, memory access patterns, and state changes that occur. This log is essential for debugging, verification, and auditing the correctness of complex digital processes.
Context
In blockchain technology, execution traces are particularly relevant for zero-knowledge proofs and rollups, where they serve as evidence for off-chain computations. The ability to efficiently generate and verify these traces is a critical technical challenge for scaling decentralized applications. News often covers advancements in cryptographic techniques that compress these traces, allowing for more efficient on-chain verification and reduced transaction costs.
This research introduces the first sublinear-space zero-knowledge prover, reframing proof generation as a tree evaluation problem to unlock on-device verifiable computation.
