Solana Alpenglow Mainnet Activation Targets 150ms Finality

Solana Alpenglow began mainnet activation on October 21. The upgrade targets 150ms transaction finality versus 12.8 seconds before. Actual speed depends on network conditions and the old system runs for a while. Validator votes no longer count as block transactions so reported totals may drop without user activity falling. SOL traded near $106.85 up 0.39% with $108 to $109 as next recovery area.
