ZK Coprocessor

A system that runs heavy computation or reads deep historical chain data off-chain, then returns the result to a smart contract with a zero-knowledge proof that it was computed correctly. The contract verifies the small proof instead of paying gas to re-execute the work — giving it trustless access to computation and history it could never afford on-chain. Examples include Axiom (over Ethereum history) and general zkVMs like RISC Zero. The proof guarantees honest execution of the proven program, not that the program's logic is correct.
