EigenLayer  is a protocol that acts as a “re-staker,” basically using a combination of ETH and other LSTs (stETH, rETH, cbETH, ETHx, etc…) as a form of “pooled security” to assure operators of the protocol are acting honestly. If operators act dishonestly on EigenLayer, they are subject to slashing conditions. Essentially, EigenLayer allows new projects to borrow Ethereum’s robust security. By incorporating restaking as a new primitive, EigenLayer empowers users and protocols to actively borrow Ethereum’s security offerings and validate new applications on the network, thereby strengthening the overall integrity and resilience of the Ethereum ecosystem alongside the protocols leveraging EigenLayer. All this also acts to further reduce the start-up cost of protocols.
