TechFlow reports, on October 18, the Solana Improvement Proposal SIMD-0337 introduced a block tagging feature to enable the fast leader handoff mechanism in Alpenglow. This technology allows leaders to immediately begin block production based on the anticipated parent block without waiting for confirmation, advancing 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 tags—BlockHeader and UpdateParent—ensuring security against malicious behavior while maximizing network throughput. Full technical details have been published on GitHub.
