Network Upgrades and Record Activity: Alpenglow, BLS Warning, and 1.32B Weekly Transactions

Alpenglow upgrade targeting 150ms finality is not live yet (expected with Agave 4.3 in October). A critical BLS pubkey rule change since July 22 could silently drain staking yields for delegators if not properly managed. Solana cut slot time to 350ms, targeting 200ms. New record: 1.32B non-vote transactions in a week, confirming real demand acceleration. Burn surged to $87K, strongest in 7 months. Solana DApps generated $35M weekly revenue, a 29-week high. These metrics validate network utility beyond memecoins.
