Restaking
Also known as: Extended Staking, Reused Stake, Shared Security Staking
A process where staked assets are reused to secure additional protocols or services, extending utility and earning potential.
Restaking allows assets that are already staked in one protocol (e.g., Ethereum's Proof of Stake) to be used again as collateral to secure other services, such as oracles, bridges, or rollups. This enhances capital efficiency by unlocking additional yield and network security without unstaking. EigenLayer pioneered this concept on Ethereum, enabling validators to opt-in and extend trust to new systems. Restaking introduces economic alignment and shared security, but also adds complexity and risk if not carefully managed. It is a foundational concept in the modular blockchain ecosystem.
