The Protocol: ETH’s Fusaka Upgrade Goes Live on Hoodi, Mainnet Next

Why It Matters

Fusaka’s efficiency gains could reinforce Ethereum’s dominance in scalable DeFi applications, while BOB’s engine unlocks trillions of BTC liquidity for lending and Ledger’s refresh strengthens institutional crypto custody.

Summary

Ethereum completed the final Hoodi testnet rehearsal of its Fusaka upgrade, clearing the path for a mainnet hard‑fork activation. The upgrade’s core feature, PeerDAS, lets validators verify only data segments, cutting bandwidth use and transaction costs after the earlier Pectra upgrade. The successful run follows prior simulations on Holesky and Sepolia, confirming readiness for mainnet deployment. In parallel, BOB introduced a Bitcoin Vault Liquidation Engine for partial liquidations of BTC‑backed stablecoin loans, and Ledger unveiled the Nano Gen5 hardware wallet along with a revamped software suite.
