EigenLayer

EigenLayer is a restaking protocol built on Ethereum that enables validators to secure additional protocols and applications beyond Ethereum's base layer. By allowing ETH stakers to "restake" their tokens—committing them to secure other networks and services simultaneously—EigenLayer creates a shared security model where validators earn additional rewards for supporting multiple protocols. This mechanism reduces the capital requirements for new blockchain networks to achieve security while maximizing returns for Ethereum validators participating in the ecosystem. Example: Eigenlayer has been integrated by multiple rollup and data availability solutions seeking to bootstrap their own security. Projects like Babylon, which brings Bitcoin staking to Ethereum, leverage EigenLayer's restaking infrastructure to tap into Ethereum's validator set and distributed consensus mechanisms. Why it matters for blockchain infrastructure: EigenLayer democratizes protocol security by allowing smaller projects to access Ethereum's robust validator network without building their own. This significantly reduces barriers to entry for new blockchain innovations and strengthens the broader Web3 ecosystem's security posture through efficient capital allocation.
