Solana (SOL) moved to the Alpenglow consensus protocol on October 21, 2026, with finality targeted at 150 milliseconds, according to PR Newswire. The Solana price is 100.65 USD as of October 27, 2026, down 0.43 percent compared with the UTC daily close of October 26, 2026.

Alpenglow targets 150-millisecond finality

The upgrade replaces TowerBFT, Solana's previous consensus protocol, with Alpenglow. Finality is the point at which a transaction can no longer be reversed. Anza said the new system targets finality of 150 milliseconds, compared with 12.8 seconds under the earlier process, according to PR Newswire.

The handover occurred at slot 459,653,000 on October 21, 2026. The change moved validators away from TowerBFT and completed the migration on Solana mainnet-beta, according to Unchained. The 150-millisecond figure remains a target for transaction finality rather than a guarantee for every application or user experience.

Network activity reached 1.88 million addresses

Solana recorded 1.88 million unique active addresses on October 9, 2026, the highest level in 13 months, according to TokenPost. A unique active address is an account that sent or received at least one transaction during a day; it does not represent a confirmed individual user.

Fund flows offered a separate counterpoint. U.S. spot Solana exchange-traded funds recorded 24.8 million USD in net outflows for the week ending October 9, 2026, ending 14 consecutive weeks of inflows, according to Yahoo Finance. The same report said fund net assets fell from 1.90 billion USD to 1.73 billion USD during that week.
