EigenLayer (EIGEN) is a protocol on the Ethereum blockchain that introduces a concept known as "restaking." Restaking allows Ethereum stakers to reuse their staked ETH or Liquid Staking Tokens (LSTs) to secure additional decentralized applications (dApps) and services within the EigenLayer ecosystem. By opting into EigenLayer's smart contracts, users can earn additional rewards while contributing to the security of various protocols, without needing to set up new validator networks.
The EIGEN token plays a central role in this system. It helps secure actively validated services (AVSs), such as bridges, dApps, and oracles, that rely on EigenLayer for their security. EigenLayer uses a pooled security model, where restaked ETH supports these services, providing a more interconnected ecosystem on Ethereum. This mechanism allows EigenLayer to reduce capital requirements for new projects, enhancing security and encouraging more innovation on Ethereum.
Stakers can either delegate their ETH to operators or act as operators themselves. Operators manage the network and select which services to support, earning rewards in return. The EIGEN token is also used in governance and slashing mechanisms to maintain network integrity, offering a system where stakers have control over which services their assets support.
