EigenLayer is an innovative project that introduces Active Verification Services (AVS) by re-staking ETH, allowing Ethereum's security and trust foundation to be leased to other systems. EigenLayer users protect other systems by re-staking their ETH and may be at risk of stake slashing. AVS are systems that require distributed verification semantics. They use EigenLayer to enhance the security and functionality of the network. The article introduces 10 Eigen AVS ecological projects worthy of attention, including EigenDA, AltLayer, Omni, Lagrange, Aligned Layer, Hyperlane, Witness Chain, Eoracle, Drosera and Ethos. These projects cover areas such as data availability, rollups re-staking, cross-chain interoperability, modular oracle networks, security incident response protocols, and the security of the Cosmos chain.
