Restaking goes live (EigenLayer)

Re-use staked ETH to secure new services and earn extra yield — a new shared-security primitive, and a new layer of risk.

Staked ETH secures Ethereum. Restaking asks: could that same staked ETH *also* secure other things — oracles, bridges, data-availability layers, new chains — and earn extra rewards for doing so?

The primitive

EigenLayer lets stakers opt in to additional slashing conditions on behalf of AVSs (Actively Validated Services). The AVS rents economic security from a pool of restaked ETH instead of bootstrapping its own token and validator set from zero.

         restaked ETH
        ╱     │      ╲
   Ethereum  AVS#1   AVS#2   (oracle, bridge, DA layer…)
   (base)   extra $  extra $
        ╲     │      ╱
     also: extra slashing risk

One stake, many duties

Liquid restaking, the next layer

Just as liquid staking wrapped staked ETH into a tradable token (stETH), liquid restaking tokens (LRTs) wrap *restaked* positions — so you earn AVS rewards and still hold a composable receipt to use elsewhere in DeFi. Convenient, and another layer of abstraction stacked on the same underlying ETH, each with its own smart-contract and depeg risk.

32 ETH ─→ staked ─→ liquid-staked ─→ restaked ─→ LRT
            base       + stETH      + AVS yield   + LRT liquidity
                       liquidity
            └── every layer adds slashing / contract / depeg risk ──┘

Layers stacked on one deposit

The catch

More yield, more risk. The same capital now backs multiple slashing conditions, and risks can correlate — a bad AVS, or many sharing operators, can cascade. Restaking is a genuinely new building block; it's also a new place for systemic risk to hide.
