Alpenglow changes finality to 150 milliseconds

Alpenglow is a consensus upgrade, meaning it changes how validators agree that transactions are final. SolanaHub reported that the upgrade became active on mainnet-beta on October 21, 2026, at the start of epoch 1064. The report said finality fell from 12.8 seconds to 150 milliseconds. Finality is the point at which a transaction is treated as irreversible by the network.

DeFi Development Corp. also described the October 21 activation in an October 19 release and said its treasury balance had increased by 3,983 SOL and SOL equivalents during the prior week, reaching approximately 2,590,266 SOL and SOL equivalents, according to GlobeNewswire. The company is a public treasury holder of SOL, so its balance is separate from Solana's circulating supply.
