What is restaking? Liquid restaking, EigenLayer, and the new yield stack explained

Restaking enables cryptocurrency users to redeploy already-staked ether to secure additional protocols and generate additional yield, representing a significant but widely misunderstood mechanism in decentralized finance. Protocols like EigenLayer facilitate this practice, creating a new layer of yield opportunities while introducing novel risks to the blockchain ecosystem.

Restaking addresses a fundamental economic problem in proof-of-stake systems: idle capital. When users stake ether to secure Ethereum, that capital is committed to a single task. Restaking unbundles this commitment, allowing the same ether to perform double or multiple duties simultaneously. This innovation emerged as developers sought ways to bootstrap security for new protocols without requiring entirely separate token issuance or stake accumulation.

The mechanism works through liquid restaking derivatives that represent staked ether positions. Rather than managing multiple staking positions across different protocols, users deposit their staked ether into a liquid restaking platform, which then distributes that capital across various protocols requiring security services. The yield stack compounds—users earn base staking rewards from Ethereum plus additional rewards from the protocols they're securing.

This model creates systemic implications worth examining. Concentrated restaking introduces correlation risk: if one protocol being secured fails or faces exploitation, it could trigger cascading failures across multiple dependent systems sharing the same underlying security. The practice also potentially diverts security resources from Ethereum itself during critical periods. For investors, restaking offers genuine yield enhancement but requires understanding the additional protocol risks they're accepting beyond standard staking.

The ecosystem is consolidating around major restaking aggregators, creating new forms of centralization. As these platforms grow, monitoring their governance, risk management practices, and exposure to various protocol failures becomes essential for understanding systemic stability.

• →Liquid restaking platforms act as aggregators, managing restaked capital across various protocols requiring security.
• →The practice introduces correlation risk where failures in one protocol could cascade across dependent systems.
