Definition ∞ L2 State Advancement describes the process by which the computational state of a Layer 2 scaling solution is updated and ultimately reconciled with the underlying Layer 1 blockchain. This confirms the validity and finality of off-chain computations and transactions. It secures Layer 2 operations.
Context ∞ This process is a fundamental aspect of rollup technologies and other Layer 2 solutions aimed at improving blockchain scalability. News reports on Layer 2 developments often explain how state advancement mechanisms ensure the security and data availability of transactions processed off the main chain.
