Key terms

Restaking

The practice of reusing already-staked capital (such as staked ETH) to provide cryptoeconomic security for additional services beyond the base chain. Pioneered by EigenLayer.

AVS (Actively Validated Service)

A service that uses restaked capital for its security. Examples include data-availability layers, oracle networks, cross-chain message verifiers, and fast-finality gadgets. Operators opt in to validate AVS in exchange for fees and exposure to AVS-specific slashing.

Operator

An entity (often a professional node-running firm) that runs the software required to validate one or more AVS. Operators receive delegated stake from restakers and earn AVS fees in exchange for accepting slashing risk.

Delegator

A user who restakes their ETH or liquid-staking tokens by delegating to an operator. Delegators receive a share of AVS fees and bear a proportional share of any slashing the operator incurs.

Native restaking

Restaking model in which a solo validator points their Beacon Chain withdrawal credentials at EigenLayer, enabling EigenLayer to enforce AVS slashing against the validator's 32 ETH directly.

Liquid restaking

Restaking model in which a user deposits a liquid-staking token (stETH, rETH, cbETH) into EigenLayer rather than staking natively. Currently the dominant restaking flow because most ETH staking is intermediated through LSTs.

Cascading slashing

The risk that a single operator misbehavior triggers slashing across multiple AVS simultaneously, potentially exhausting the operator's stake before all AVS can be paid. A core concentration risk specific to restaking.

Cryptoeconomic security

Security that comes from the economic value of staked capital that would be slashed for misbehavior. Distinct from cryptographic security (which comes from mathematical proofs) and trusted-party security.

Withdrawal credentials

The on-chain address that controls where a Beacon Chain validator's stake can be withdrawn. EigenLayer requires validators to set withdrawal credentials to an EigenLayer-controlled contract so that AVS slashing can be enforced before exit.

"Don't overload consensus"

A May 21, 2023 essay by Vitalik Buterin arguing that restaking is fine if it stays contained within its own contracts, but dangerous if it creates pressure on Ethereum's social layer to fork or arbitrate disputes on behalf of restaked applications.
