Definition ∞ State transition proofs are cryptographic assurances that demonstrate a system has moved from one valid state to another in accordance with predefined rules. These proofs confirm the integrity of computational processes without revealing the full transaction history or intermediate steps. They are fundamental to verifying computations efficiently in scalable systems.
Context ∞ In blockchain technology, particularly for scaling solutions like rollups and other Layer 2 protocols, state transition proofs are essential for off-chain computation verification. They allow a main chain to confirm the correctness of thousands of transactions processed elsewhere by checking a single, compact proof. This mechanism is a key area of development aimed at significantly increasing transaction throughput and reducing costs on congested blockchain networks.
