The block time is currently set to **6 seconds**, following [[Substrate]]'s default BABE configuration [109]. However, this parameter is adjustable to meet specific network needs: a shorter block time (e.g., 3 seconds) could increase transaction throughput but might also raise risks like increased uncle block rates or reduced decentralization due to increased synchronization demands. Conversely, a longer block time (e.g., 12 seconds) could enhance stability at the cost of throughput, a trade-off under active evaluation for future optimizations. GRANDPA finality operates independently, typically finalizing blocks within 1-2 rounds regardless of block time.
