What is restaking?
In short
Restaking is the use of funds that are already staked to secure additional services or networks, with the potential for extra rewards but also additional risks.
Can the same collateral back more than one job? That’s the idea behind restaking, i.e. reusing staked funds. In staking, a validator locks up cryptocurrency to take part in securing a network. With restaking, that capital can also support additional services, with different rules and obligations.
Think of a professional who uses the same cash deposit as a guarantee to take on more projects. They may earn more fees, but their deposit is now exposed to more potential failures. The capital doesn’t double; it takes on extra responsibilities.
On Ethereum, for example, there are restaking mechanisms that use staked ETH or tokens representing a liquid staking position. Through the relevant protocols and node operators, the capital can support services such as data verification. How you participate, the rewards and the possible penalties depend on each implementation.
Why it matters
For a new service, restaking offers a way to tap existing capital and validation infrastructure instead of having to build everything from scratch. That can make it easier to launch, but it doesn’t automatically pass on all of the original network’s security guarantees.
For crypto holders, there’s the potential for additional rewards on top of those from staking. We believe the key point is the trade-off between reward and additional risk, not just the yield an app displays.
What to watch out for
Where applicable, breaking the rules can lead to a cut of the staked funds (slashing). So a failure in an additional service could affect the locked-up funds. There are also risks from bugs in smart contracts, from node operators and from dependencies between protocols.
Restaking isn’t the same as liquid staking: the latter gives you a token that represents your staking position, while the former adds security obligations. If an intermediary token is involved, you also need to check whether it can be redeemed, its liquidity and the withdrawal times. The extra rewards aren’t guaranteed and don’t rule out a loss of capital.
