First, the staking mechanism lacks flexibility: validators must stake a fixed 32 ETH, causing large-scale stakers to manage multiple validator nodes to distribute funds, increasing operational complexity and network load. Secondly, the validator exit process has security risks: validator exit operations depend on validator keys (BLS keys), and if keys are lost or managed by different parties, funds may not be recovered in time. Additionally, data storage efficiency is unbalanced: although the Dencun upgrade introduced Blob storage, some Layer2 still prefer lower-cost Calldata, hindering Blob's popularization and overall data efficiency improvement.
