MECHANISM, BENEFITS, AND RISKS OF RESTAKING

Restaking, also known as compounding, is a process in which investors reinvest the rewards they earn from staking crypto back into the staking pool to generate additional profits. Staking is the process of locking assets in a cryptocurrency wallet to support the operations of a blockchain network. In exchange for staking, participants receive rewards, usually in the form of tokens, as an incentive to encourage staking, helping to secure and validate transactions on the network.

With restaking, instead of withdrawing these rewards, investors choose to reinvest them, increasing the amount staked and thus, increasing their potential rewards in the future. This compounding effect can significantly amplify the overall profit generated from staking activities over time.

Mechanism of Restaking

For example, on the largest network today, Ethereum: Restaking projects will deploy smart contracts on the Ethereum network so that those who stake ETH can restake their assets on external protocols. These projects will function as a channel through which you can restake your staked ETH tokens, as well as a decentralized delegation market for stakers looking to compound their rewards.

There are 2 methods of restaking:

Native restaking: Allows you to restake your ETH directly for the Restaking protocol.

LSD Restaking: Restaking liquid staking tokens (LST). You can stake ETH on liquid staking platforms like Lido and Rocket Pool. Liquid Staking is less complex and has a much lower minimum stake requirement compared to running your Ethereum validator. Then, you can restake the LST received from these LSD protocols to continue receiving rewards.

Advantages

More rewards: The most obvious advantage of restaking for validators is the ability to compound staking rewards by staking on other protocols.

Reducing the initial costs of new protocols: By restaking Ethereum's asset pool, new protocols can economically benefit from Ethereum's security services without needing to start their own validation service.

Maintaining protocol sovereignty: By building on restaking protocols like EigenLayer, protocols will be able to flexibly customize their architecture without having to adhere to rigid rules imposed on the Ethereum layer 2 chain.

Disadvantages

Slashing: When you stake ETH, you risk being slashed if the validator behaves maliciously. Restaking increases the risk, and you may lose staked ETH if you engage in harmful activities on the protocol.

Risk to Ethereum's performance: Restaking projects are concerned that with Ethereum's computational power being redirected to secondary networks, there may be computational overload issues for Ethereum's consensus layer.

Centralization risk: Restaking on protocols like EigenLayer may attract ETH stakers with promises of high profits, leading to increased centralization of networks and a decrease in the number of individual ETH stakers.

While still in its early stages, Restaking is an interesting approach to both network validation and security, as well as how users can positively contribute to both. In particular, restaking Ethereum could set a precedent for how blockchain protocols harness the power of collective participation and pooled economic incentives to shape the future of decentralized finance.
