Definition ∞ RAM programs are computational models that represent programs operating on random access memory, where data can be accessed directly by its address. In the context of zero-knowledge proofs, proving the correctness of a RAM program execution involves demonstrating that the program ran as specified without revealing its inputs or intermediate states. This allows for verifiable computation over a more general class of programs than traditional arithmetic circuits. It provides a flexible framework for expressing and verifying complex operations.
Context ∞ The development of efficient zero-knowledge proofs for RAM programs is a significant area of cryptographic research, aiming to broaden the applicability of verifiable computation. Challenges include minimizing proof size and generation time for arbitrary program logic. Observing new proof systems and their benchmarks for general-purpose computation provides insight into the progress toward more versatile verifiable execution.
