[Ethereum Fusaka Hard Fork Completes Final Testnet Activation, Mainnet Expected to Launch in December] Ethereum's upcoming hard fork, Fusaka, was successfully activated on the Hoodi testnet on Tuesday, marking the final testing phase before mainnet deployment. Previously, Fusaka had completed deployments on the Holesky and Sepolia testnets earlier this month. The Ethereum Foundation stated that the mainnet activation will occur at least 30 days after the completion of testing on Hoodi, with the core development team tentatively scheduling the hard fork for December 3. Fusaka aims to enhance the scalability, efficiency, and security of the Ethereum blockchain through backend optimizations. Key improvements include increasing the block gas limit, expanding "blob" capacity, and introducing new node security features. This upgrade encompasses more than ten Ethereum Improvement Proposals (EIPs), with EIP-7594 being particularly significant. This proposal optimizes Layer 2 data availability through Peer-to-Peer Data Availability Sampling (PeerDAS).

[Tether Considers Adjusting U.S. Political Donation Strategy] Tether CEO Paolo Ardoino stated that the company is dissatisfied with the operations of the crypto-focused political action committee Fairshake, believing it has become a tool controlled by a certain company, though he did not disclose the specific name. Reportedly, Fairshake has invested $133 million in the 2024 U.S. election to support pro-crypto candidates. Since Tether is headquartered in El Salvador, it cannot directly donate to U.S. political campaigns, but the company plans to establish an entity in the U.S. by the end of 2025, led by former Trump crypto advisor Bo Hines. In recent years, several crypto-focused political action committees have been established, some closely tied to Republican candidates, including organizations associated with Cantor Fitzgerald Bank, which is led by Howard Lutnick, the Commerce Secretary under the Trump administration. Tether is currently evaluating potential collaborations with different political action committees to optimize its political strategy.
