[Anza Launches Constellation Protocol, Achieving 50ms Block Times with Multi-Concurrent Proposer Mechanism] According to SolanaFloor, Solana's core development team Anza has launched the Constellation protocol, a multi-concurrent proposer protocol that reduces Solana's block time to 50 milliseconds, making it the fastest blockchain at the protocol level in terms of economic cadence. This protocol replaces the single-leader model, eliminating exclusive control over transaction inclusion and ordering through concurrent proposers. It enforces fairness at the protocol level without relying on trusted third parties or client modifications, while largely maintaining the validator economic model.
