Key Takeaways
Restaking revolutionizes staking dynamics by offering added value to both stakers and protocols.
Previously, tokens were locked into single protocols, limiting their utility, but restaking allows stakers to diversify contributions across multiple protocols.
Restaking unlocks greater rewards from a single stake, enhancing the overall efficiency and profitability of staking.
Transforming staked assets into flexible resources paves the way for expanded use cases and further evolution in the realm of staked assets. However, with increased rewards come elevated risks, including slashing, centralization, and systemic vulnerabilities.
The resurgence of speculative investment chasing high rewards raises concerns.
What is staking?
Staking involves locking your tokens to contribute to validating a proof of stake network. In return for locking your tokens, you receive rewards after the locking period ends. The locked tokens serve as collateral to ensure validators adhere to their duties honestly. If they act dishonestly or violate rules, a portion of their assets may be slashed as a network-imposed penalty.
When you stake Ether, you receive a liquid token, acting as a certificate of ownership for your staked tokens. This token holds the same value as the staked token, granting access to retrieve your tokens at the end of the locking period.
What is restaking?
Restaking involves staking your liquid token on another platform, enhancing the utility of your staked asset and enabling additional rewards. Instead of staking your ETH directly, you stake tokens that represent your staked ETH from other platforms like Lido or Rocket Pool. This allows for a more flexible and efficient staking experience. This technology notably allows new protocols to leverage the security provided by Ethereum's proof of stake network, with EigenLayer emerging as a key player in this domain.
Benefits of restaking:
Flexibility and efficiency: Restaking lets traders use staked assets in different financial activities without unstaking. This provides liquidity and maintains reward potential, enhancing capital allocation efficiency and asset utility.
New protocol security: New protocols and networks, especially in their early stages, require robust security systems. Restaking provides access to a broad pool of validators, significantly enhancing security during protocol development.
Scalable and cost efficient security: Restaking services enable protocols to adapt security levels based on demand. By utilizing a rental service for security, protocols can increase security during peak times by contracting validators and scale down during normal conditions, ensuring cost-effective security scaling.
Risks of restaking:
Compounded slashing risk: The slashing risk increases as you restake the tokens to a second protocol, which will have its own compliance guidelines.
Centralization risk: As validators using restaking offer high APY, they could attract an amount of token large enough to control the stake. It would lead to the loss of neutrality for the network.
Systemic risk: Restaking is a way to leverage the use of your staked token. Leveraging to high extents could lead to a potential systemic risk as big players could hold a significant part of the staked Ethereum.
Example of restaking service: EigenLayer
EigenLayer facilitates crypto-economic security on Ethereum by creating middleware that transforms staked ETH into commodities for rental, enhancing security for other protocols. Stakers can commit native Ethereum tokens or Liquid Staking Tokens (LST) to EigenLayer, earning rewards by providing security services to various protocols. LSTs from platforms like Ankr, Binance, Origin, Lido, and Coinbase can be staked on EigenLayer under Liquid Restaking. Validators in this program agree to additional slashing conditions. Currently, there are no services on EigenLayer for restakers to secure, so they earn restaked points instead.
Since its launch, EigenLayer has grown to become the second largest restaking protocol, with $15.67 billion in total value locked (TVL) by users who have been anticipating an airdrop.
How can real yield be generated by protocols?
When users stake their tokens in a protocol, they become eligible to receive rewards in the protocol's native token. There was a period when protocols offered yields as high as 800% Annual Percentage Yield (APY). While these returns appeared exceptionally enticing, such yields often implied significant inflation, as the protocol issued rewards in its own token, effectively diluting the market capitalization.
For a token to maintain its value despite the issuance of new tokens, demand must increase at a rate equal to or greater than the rate of token emissions. However, dedicating a portion of revenue to rewarding investors means the protocol will have fewer funds in its treasury for other investments.
As an illustration, the APY currently offered to Ether stakers is around 3.4%. By restaking on a protocol like EigenLayer, users could potentially double that yield to approximately 7%, while also benefiting from potential capital gains associated with ETH.
However, the lesson from the DeFi summer, marred by significant fraud and loss, looms large as a reminder. As restaking gains traction, the underlying security implications and the sustainability of high yields on single assets must not be underestimated. In restaking summer, the potential for a precipitous downfall exists, not from outright fraud, but from a collective oversight of the intricate security dynamics at play.
