Anza researchers proposed SIMD-0675 to improve Solana's validator block production by scheduling validators geographically instead of randomly. This geo-aware leader schedule groups nearby validators to produce blocks consecutively, reducing handover delays by 53% from 36.2 ms to 17.0 ms in simulations using real mainnet data. Validators must register their location on-chain to participate, but their stake and slot shares remain unchanged. The change supports Solana's upcoming Alpenglow consensus protocol, which targets faster finality and benefits from reduced latency. The proposal is now open for community review as Solana moves Alpenglow through testnet phases.
