Solana Proposal Speeds Up Block Production with SIMD-0337

Solana’s latest proposal, SIMD-0337, introduces a new block tagging system to accelerate the leader transition process in Alpenglow. This innovation allows leaders to begin block production based on expected parent blocks without waiting for confirmation, reducing block production time by approximately 120 milliseconds and boosting inter-block reliable latency (IBRL) by about 7.5%. This new mechanism is implemented using two tags: BlockHeader and UpdateParent, ensuring security against malicious actions while maximizing network efficiency.
