Ethereum researchers propose a kill switch for staking rewards: A draft Ethereum Improvement Proposal published on August 4 could fundamentally reshape how the network rewards its validators, with researchers including Justin Drake proposing a mechanism that would gradually burn validator rewards as the amount of staked ETH grows. The draft, provisionally labeled EIP-8361 and titled "Tapered Issuance," introduces a system that begins reducing or eliminating staking rewards once total staked ETH crosses a defined threshold. The proposal has reignited one of the most contentious debates in the Ethereum community over monetary policy and the risks of unchecked staking growth.

CLARITY Act Delay May Not Stop Crypto After All: The Digital Asset Market Clarity Act does not have the time to clear the Senate floor before the August 8 recess, and even if it does, it may be confined to the last possible moment, but Bitwise Chief Investment Officer Matt Hougan argues that a stall is not necessarily the end of the road. Hougan maintains that the SEC's shift in posture under Chair Paul Atkins matters more than the bill itself, suggesting the agency can deliver meaningful regulatory clarity even without congressional action. Senator Bill Hagerty continues to push for a vote before recess, calling the legislation a non-negotiable priority for American competitiveness in digital assets.
