Gm frENS. Happy Thursday, the week is almost over, but we've got exciting news!

• Fusaka is targeted for mainnet on December 3rd.

• Coinbase integrates DeFi lending.

• CoinCenter releases a report on identity.

• EF funds an Ethereum Research Center.

Fusaka is coming! Ethereum core developers have scheduled a tentative timeline for the Fusaka upgrade, targeting a mainnet activation on December 3, 2025. In today’s ACDC #165 call, developers agreed to finalize the upgrade spec with a code freeze by September 22, followed by testnet client releases beginning September 25. Fusaka will first go live on the Holesky testnet on October 1st, then Sepolia on October 14th, and Hoodi on October 28th. If all testnet deployments proceed smoothly, mainnet client releases will follow in early November with the upgrade activation on December 3rd. Alongside Fusaka, developers also scheduled Blob Parameter Only (BPO) forks, which are consensus-only upgrades designed to adjust blob targets and limits. Planned for Q4 2025, Fusaka is Ethereum’s next major upgrade, bringing scaling improvements through PeerDAS. PeerDAS allows nodes to verify blob data availability without downloading full datasets, boosting data capacity and substantially lowering costs for Ethereum rollups.

Coinbase integrated DeFi lending directly into its exchange, offering users up to 10.8% APY on USDC deposits. The integration is powered by the Morpho lending protocol on Base, featuring vaults curated by Steakhouse Financial, Coinbase creates a smart contract wallet that routes deposits from Coinbase into Morpho. This launch builds on Coinbase’s crypto-backed loans to create a “DeFi mullet” with fintech simplicity on the front end and institutional-grade DeFi infrastructure on the back end. The feature is rolling out to most U.S. users and allows instant withdrawals, no lockups, and continuous interest accrual.

The Ethereum Foundation has pledged $500,000 per year for three years, with the potential to provide up to $6 million total over time, to establish the Columbia-Ethereum Research Center for Blockchain Protocol Design at Columbia Engineering in New York. The Center will support competitive research proposals in computer science, engineering, economics, and policy, along with graduate and postdoctoral fellowships. The center will also host educational programs like summer bootcamps, the Columbia Cryptoeconomics Workshop, as well as an industry researcher-in-residence program.
