Before 2026 is out, eight different chains ship their biggest upgrades in years — and the first lands this week. Zcash's Ironwood goes live July 28 (new shielded pool, quantum-recoverable funds).

Zcash update is followed by Ethereum's Glamsterdam, Solana's Alpenglow, Polkadot's JAM, and Cardano's largest upgrade ever. Chainlink is bringing Wall Street's DTCC settlement on-chain, while Polygon and BNB Chain race toward 100k and 10k+ TPS.
