Solana has introduced the SIMD-0337 proposal, which brings a fast leader transition mechanism to enhance network performance

BlockBeats News, October 18th, Solana Improvement Proposal SIMD-0337 introduces the Block Marking feature, enabling the fast leader transition mechanism in Alpenglow. This technology allows the leader to immediately start block production based on the expected parent block without waiting for confirmation, advancing the block production time by approximately 120 milliseconds and improving IBRL (Inter-Block Reliable Latency) by about 7.5%. The new mechanism is implemented through two markers, BlockHeader and UpdateParent, ensuring both security against malicious behavior and maximizing network throughput. The full technical details have been published on GitHub.
