Puffer Finance, an active liquidity re-staking protocol on EigenLayer, has introduced a solution called Based Rollups. This aims to incorporate ETH mainnet validators to provide a more secure and efficient decentralized solution for Rollups. Based Rollups seeks to achieve decentralized ordering by utilizing L1 proPoser for transaction sequencing, reducing the current risk of overly centralized Rollup sequencers, significantly lowering transaction costs, and enhancing system activity, thus improving the security and efficiency of Rollups.
