EigenLayer is designed to extend Ethereum security to software modules such as bridges, oracle networks and consensus mechanisms by utilizing restaking to offer pooled security mechanisms. They’re built on top of the network.
The initial mainnet launch will only include restaking, with operators and validators being part of a second launch iteration in the works. Native staking will also be available in the initial launch.
