Definition ∞ Off-Chain State Progression describes the advancement or modification of data and application logic that occurs outside the main blockchain ledger. This process leverages layer-2 solutions or sidechains to execute transactions and computations more efficiently and at a lower cost. Only periodic summaries or dispute resolutions are committed to the primary chain, reducing its burden. It allows for scalable and rapid application execution.
Context ∞ Off-chain state progression is a fundamental concept in addressing the scalability limitations of many blockchain networks, enabling complex decentralized applications to function effectively. Ongoing efforts concentrate on developing secure and interoperable off-chain solutions that maintain the integrity of the underlying blockchain. This technology is critical for the widespread adoption of decentralized applications and services.
