On March 26th, according to market news, Solana's core development team, Anza, has launched the Constellation protocol. This is a multi-concurrent proposer protocol that reduces Solana's block time to 50 milliseconds, making it the fastest blockchain in terms of economic beat speed at the protocol level. The protocol replaces the single leader model by eliminating exclusive control over transaction inclusion and ordering through concurrent proposers, enforcing fairness at the protocol level without relying on trusted third parties or client modifications. The validator economic model remains largely unchanged.
