summary
ZISK by Polygon ZKVM aims for real-time proof generation and trades cost for subsecond latency, using a transpiler that runs RISC5 logic as Intel assembly to reach 1.5GHz RISC5 execution, parallelizing proofs across server clusters and leveraging GPUs when cost-effective, plus an aggregation stack that hits 100–150 ms aggregation. Work is production-ready: optimized compilers, multi-air arithmetization, and security learnings. Also explores program obfuscation with embedded keys to enable a Bitcoin–Ethereum bridge without forks and flags centralized sequencers as a decentralization risk.
