Solana Prepares for Alpenglow Upgrade Targeting 150ms Finality as Price Declines Mid-October
Solana's Alpenglow consensus upgrade targets 150ms finality on October 21 while SOL trades lower across mid-October and Grayscale calls the chain an overlooked bet.

What happened
Solana is scheduled to activate its Alpenglow consensus upgrade on October 21, targeting transaction finality of approximately 150 milliseconds compared to the current 12.8 seconds.

SOL has declined across mid-October, trading at $102.01 on October 15, $104.53 on October 17, and $103.96 on October 20. Grayscale head of research Zach Pandl said at Token2049 that smart contract platforms including Solana are not a consensus trade among crypto-native investors. Solana ETF outflows totaled $12.67 million from Bitwise's BSOL fund. The broader cryptocurrency market also declined during this period.
