L1 Block Time

Definition ∞ L1 Block Time represents the average duration it takes for a new block of validated transactions to be added to a layer-1 blockchain. This metric directly impacts the speed at which transactions achieve finality on the base network. A shorter block time generally indicates faster transaction confirmation but can also influence network stability and decentralization. It is a fundamental parameter defining a blockchain’s throughput characteristics.
Context ∞ L1 Block Time is a critical performance indicator often discussed in news concerning blockchain network upgrades and scalability debates. Changes to this parameter can significantly affect transaction costs and user experience across the ecosystem. Optimizations in block production are ongoing efforts to enhance network efficiency.
