To address the challenge of maximizing the utility of LSTs, the concept of restaking emerges as a crucial mechanism, creating a marketplace for Ethereum's validation trust. Restaking involves the reutilization of bonded assets, either natively or as liquid staked Ether, to bolster external systems such as rollups, RPCs, data availability, oracles, and more, providing them with an additional layer of economic security.

Restaking allows users to leverage their staked assets further by restaking them to secure other networks or applications. This opens up a world of possibilities for boosting capital efficiency and earning additional rewards. By enabling the same assets to be used for multiple purposes, restaking significantly enhances the capital efficiency of the ecosystem. It also provides additional security layers for various blockchain services, thereby fostering a more secure and interconnected blockchain environment.

At the forefront of this endeavor stands EigenLayer (opens in a new tab), which envisions enhancing the capital efficiency of staked assets and the machinery utilized for Ethereum staking. In addition to Eigenlayer core offering, newer entrants into the restaking arena like Karak (opens in a new tab) and Symbiotic (opens in a new tab) propose more features and flexibility for restaking.
