Solana, Avalanche, XRP Ledger and Ethereum roll out major network upgrades
- —Solana: Alpenglow hits testnet Sept 23, finality cut from 12.8s to 150ms
- —Avalanche: Helicon live Sept 22, unstaking reduced from 14 days to 48 hours
- —XRP Ledger: Batch (XLS-56) set for Sept 29, needs 28 of 35 validators
- —Ethereum: Glamsterdam with parallel execution and ePBS due in Q4 2026
Why it matters: Faster finality and separated execution make these chains more viable for payments and institutional use, though several upgrades remain in testnet or on the roadmap.
