Solana will launch its Alpenglow consensus upgrade on October 21, 2026, aiming to reduce network finality to 150ms by moving voting processes off-chain.

The Solana blockchain will deploy the Alpenglow upgrade on October 21, aiming to reduce transaction finality time to 150 milliseconds.

Anza researchers proposed a geo-aware validator scheduling system for Solana that could cut block handover latency by 53%.

Solana’s Alpenglow upgrade has reached a 54ms median finalization time on testnet, significantly outpacing its design targets ahead of the planned mainnet release.

Solana developers have refuted rumors of an Alpenglow mainnet launch on September 28, emphasizing a cautious testing approach for the consensus upgrade.
