ChainCatcher news, according to Cointelegraph, the total value of SOL tokens staked on the Solana network briefly surpassed the market value of staked ETH on Ethereum yesterday.On-chain data shows that there are 505,938 unique wallets on the Solana network staking SOL worth $53.9 billion, with an annual staking yield of 8.31%; on the Ethereum chain, there are a total of 34.7 million ETH participating in staking, valued at $53.93 billion. The high validation threshold of 32 ETH (approximately $50,000) has led many stakers to shift from node staking to liquid staking protocols, which is a key reason for the reduction of native staking on the Ethereum chain. Currently, about $21.5 billion in funds are participating in liquid staking on the Ethereum chain, with Lido alone accounting for 88% of the market share, exacerbating concerns about Ethereum's centralization, and Ethereum developers are exploring solutions to promote staking decentralization.

According to ChainCatcher news, as shown on the Aptos governance proposal page, community member moon shiesty submitted the AIP-119 proposal, suggesting a monthly reduction of 1% in the staking annual yield over the next three months, to an eventual rate of approximately 3.79%. This proposal aims to serve as a preliminary attempt at restructuring the Aptos economic model, with plans for gradual implementation over six months to assess its potential impact.The proposal argues that the current ~7% staking yield is too high, reducing capital efficiency and encouraging the community to explore riskier or costlier opportunities such as restaking, DePIN infrastructure, MEV, and DeFi rewards. Although lowering staking rewards may reduce the incentives for holding APT, the proposal believes that the reduction in inflation combined with new reward mechanisms is expected to offset the impact.The proposal points out that this move may impact small validators and suggests considering support for validators holding less than 3 million APT through a community staking program, as well as discussing more efficient long-term incentive methods. The proposal is expected to undergo community and foundation review in the next four weeks, with a mainnet vote to be submitted in the fifth week.
