Puffer Finance is a decentralized protocol that enables anti-slashing and at-home staking on Ethereum by utilizing a low bond requirement and introducing Secure-Signer, a remote-signing tool that prevents slashable offenses. Puffer aims to diversify the validator set and reduce centralization in Ethereum’s proof-of-stake network while addressing the challenges faced by solo validators. It provides a permissionless staking pool and tools to enhance the safety and viability of at-home staking.
