The Ethereum Foundation has unveiled a $220 million security fund, sourced from unclaimed compensation related to the 2016 DAO hack. This initiative aims to enhance the Ethereum network's security by providing grants for critical security projects and staking a portion of the funds to generate sustainable revenue. The fund's establishment marks a significant reinvestment into the network's resilience against digital threats. The fund will support projects focused on smart contract auditing, formal verification research, and consensus-layer protection. Additionally, a portion of the capital will be staked on the Ethereum network to create a self-replenishing revenue stream. This strategic move transforms unclaimed assets from a past vulnerability into a tool for future security, reinforcing Ethereum's position as a leading platform in the blockchain space.
