Puffer is a protocol built on Eigenlayer, providing a native liquid restaking solution for Ethereum Proof of Stake (PoS) validators. It offers a permissionless framework, enabling individuals to operate validators with enhanced rewards through restaking. The protocol emphasizes capital efficiency, allowing validator operation with less than 2 ETH and includes features such as slash protection and MEV strategy autonomy. The system is designed to cap its influence on the Ethereum validator set to maintain network security and decentralization.
