Solana Deploys Alpenglow Upgrade to Devnet and Testnet to Target 150ms Finality

Solana has deployed its Alpenglow consensus upgrade to the Testnet and Devnet, allowing developers to test compatibility before the mainnet launch. The upgrade aims to reduce finality time from approximately 12.8 seconds to 150 milliseconds by enabling validators to exchange votes directly rather than recording them as transactions on the blockchain. While the Solana Foundation notes that transaction statistics involving validator votes may decrease, standard user transactions and account balance queries remain unaffected. The 150ms target is currently a simulation, and exchange deposit confirmation times may still vary.
