Introduction

In the ever-evolving world of cryptocurrency and blockchain, notable innovations often focused on improving blockchain security and enhancing earning opportunities for investors. Restaking is an approach that fulfills the investors' need for high returns while improving the utility of cryptocurrency assets. While many are still skeptical about giving this approach a solid thumbs up, what is apparent is the ability of this technological advancement to substantially increase cryptocurrency utility and liquidity, enhance the security of multiple blockchains and protocols concurrently, and serve as a multiple source of income for savvy investors.

Staking, Proof-of-Stake, and Restaking

While blockchains like Bitcoin rely on a Proof-of-Work consensus mechanism where miners use computing power to ensure security and 51% control is required to successfully launch an attack, blockchains like Ethereum rely on Proof-of-Stake. This approach places the security of the blockchain in the hands of node validators, who must validate transactions to keep the network secure.

To become validators, individuals must stake (lock up) a certain amount of their crypto asset. While this approach ensures validators are rewarded for every transaction validated on the blockchain, staked assets serve as collateral that can be slashed to penalize any validators who acted maliciously or carelessly compromised the security of the blockchain.

Even though the above sounds like a good deal, what makes it unappealing is the requirement for staking, which often requires a considerable investment commitment on the part of the validators combined with the fact that tokens staked under this traditional framework remain accessible for a specified period. To resolve this problem, the modern staking approach introduces liquid staking and restaking.

This article explores the concept of restaking, highlighting its benefits and how crypto holders can benefit significantly from this innovation.

What is Restaking?

Restaking is a decentralized finance innovation that promises multiple yields on a single staked asset. First, users stake their crypto asset and receive derivative tokens; these derivative tokens and the reward earned on the original staked asset are then restaked in other ecosystems.

At its core, restaking remains an innovation that allows users to maximize crypto staking rewards while enhancing capital efficiency in the crypto space. With this approach, users can earn additional rewards on already staked assets since issuing and staking derivative tokens allow them to use the same asset concurrently to secure other blockchain protocols' security.

How does Restaking Work?

Staking: The crypto asset is first staked on the main blockchain using the traditional or liquid staking approach. Notably, Chainnodes provides users with an ETH liquid staking where anyone can stake their ETH, receives liquid staking tokens, and earns rewards.

Smart Contract: Restaking relies extensively on comprehensive smart contracts to facilitate automated transactions without delay. This way, restaking service providers eliminates trust issues and system failure.

Restaking: Restaking is only possible when original crypto assets are staked. The reward earned on these staked assets and the derivative token issued to users after staking the asset are staked again to offer additional security for other protocols.

Multiple Reward System: Once restaked, the asset starts to accrue rewards from all the ecosystems where it is being used. For instance, if a user staked ETH on the Ethereum blockchain and enabled restaking (rewards earned and derivative token issued) on three other protocols, the user earned rewards from all four (Ethereum and the 3 different protocols) protocols.

How to maximize reward through restaking

Use restaking platform: Compared to the traditional staking approach, it is apparent that users can optimize rewards on a single crypto asset. As such, using restaking platforms ensures you can earn multiple yields without needing high financial commitment.

Compound Regularly: Enabling the auto-restaking option on the service provider platforms ensures you do not constantly have to check for when to restake. This feature uses smart contracts to automatically restaked your asset, derivative tokens, and reward earned.

Diversify Staking Asset: Since restaking offers the chance to earn from multiple platforms, spreading your crypto assets across multiple staking pools allows you to enjoy the highest return and adequate security.

Challenges associated with Restaking

Sustainability issue: While restaking remains one of the leading earning frameworks in the crypto space today, many are concerned about the sustainability of this innovation. For instance, slashing may have a ripple effect on the security of several ecosystems and the interest of many people, which means one mistake can result in several people losing a reasonable percentage of their assets and jeopardize the security of blockchains.

Centralized Staking: Platforms that offer restaking are limited at the moment; hence, many have contested the ability of the restaking approach to centralized staking in the hand of few validators or platforms offering multiple incomes or higher APY to delegators through this approach.

High risk: As mentioned earlier, restaking relies extensively on smart contracts. While this approach enhances trust in the space, it also creates an endless possible point of failure—an attack on any smart contract subject assets and systems to risk.

Complexity: Ordinarily, restaking service providers relies smart contracts and advanced technology to offer this service, this requires users to understand complex cryptocurrency concepts, terms, and guides. This renders restaking a less  accessible offer to many market participants.

Conclusion

Despite the notable concerns, the launch of the first Restaking platform, EigenLayer, was a celebrated success in crypto place. We've also seen the introduction of projects like Ether.Fi providing investors with a chance to explore the potential of this attractive earning mechanism. Undoubtedly, restaking serves the purpose of crypto investors and project developers. In the coming years, more simplified offers are expected to make it accessible to the general market.
