Definition ∞ A state progression proof cryptographically verifies that a system’s state has moved correctly from one valid state to another. This proof mechanism confirms that all computations and transitions leading to a new state are legitimate and adhere to the system’s rules, without needing to re-execute every step. It is particularly relevant for scaling blockchains, allowing for efficient verification of complex off-chain computations. Such proofs significantly reduce the on-chain data storage and processing requirements.
Context ∞ State progression proofs are a foundational element for many advanced scaling solutions, including optimistic and zero-knowledge rollups, which aim to increase blockchain throughput. Research continues to optimize their generation and verification processes, making them more practical for real-world applications. Their development is crucial for enabling more complex and higher-volume operations on decentralized networks.
