According to BeInCrypto, the change will consolidate voting data into a small digital certificate, with rollout expected in stages between August and October 2026 if testing stays on track. SOL traded near $77 with a market value of about $45 billion, while the upgrade still requires validator BLS key registration and an active Validator Admission Ticket before mainnet activation."
