Eigenlayer

EigenLayer is a protocol built on Ethereum that introduces restaking, a new primitive for Web3 builders. It provides a “marketplace for trust” bringing together Restakers, Operators, and Autonomous Verifiable Services (AVSs), allowing users to stake assets to extend Ethereum’s cryptoeconomic security to additional applications on the network.

EigenLayer allows Ethereum validators to restake their ETH or Liquid Staking Tokens (LSTs) to secure other protocols called Active Validated Services (AVS). This mechanism pools security, increases the cost of potential attacks, and allows validators to earn additional rewards from various sources without extra capital lockup.

Restaking is a mechanism that allows Ethereum validators to make their staked ETH more useful by committing to secure protocols or services other than the Ethereum network itself. It enables staked ETH to be used as cryptoeconomic security for multiple protocols in exchange for protocol fees and rewards.

AVSs are services built on the EigenLayer protocol that leverage Ethereum’s shared security. They deliver services to users and the broader Web3 ecosystem, benefiting from Ethereum’s robust security guarantees without needing to replicate the costly process of securing their own network.

The EIGEN token is a major innovation introduced by EigenLayer to address “intersubjective” faults or forks. It enables an “intersubjective forking” system that resolves problems without forking the main Ethereum blockchain, securing digital tasks and services with intersubjectively attributable faults.

Key benefits include leveraging Ethereum’s staking mechanism for security, focusing on the project’s unique value without building security frameworks from scratch, quickly accessing a large network of experienced Operators, building on trust-minimized decentralized infrastructure, and seamlessly integrating with the broader Ethereum ecosystem.

Liquid restaking combines the advantages of liquid staking and restaking. It allows EigenLayer users to receive a liquid token representation of their restaked assets, representing both their original staked ETH and additional commitments made for various supported protocols. This offers flexibility for trading or using restaked positions in DeFi applications while earning rewards.

Risks include slashing risk, where validators can lose their staked ETH if they breach rules of supported AVSs; centralization risk, where a concentration of power could pose systemic hazards; and other risks such as bootstrapping new trust networks, value leakage, and weakened security due to fragmented trust networks.

EigenLayer enhances Ethereum’s security by aggregating and extending cryptoeconomic security through restaking. It allows new applications to benefit from Ethereum’s robust security model, increasing the cost of malicious attacks by consolidating otherwise fragmented pools of security.

Slashing is a penalty for improperly or inaccurately completing tasks assigned in Operator Sets by an AVS. It results in a burning or loss of funds for validators who are found guilty of malicious action regarding an AVS.

EigenLayer solves this by aggregating a ready-to-deploy network of Operators and Restaked assets, offering Cryptoeconomic Security as a Service. This frees builders to focus on core differentiators, accelerating innovation without needing to build security frameworks from scratch.

Operators are entities that run AVS software and perform validation tasks for AVSs built on EigenLayer. They register in EigenLayer and allow stakers to delegate to them, then opt in to provide various services built on top of EigenLayer.

EigenLayer removes entry hurdles for new blockchain services, spurring the creation of new applications. This competitive climate encourages improvements on earlier ideas, expanding Ethereum’s horizons and fostering new uses in decentralized platforms.

The EIGEN token has been created as the “Universal Intersubjective Work Token” to enable the “intersubjective forking” system, which resolves problems that cannot be identified on-chain but would be agreed by reasonable observers to merit penalties, without forking the main Ethereum blockchain.

While EigenLayer’s promises of higher yields might attract more ETH stakers, potentially leading to centralization, the protocol includes mechanisms like a veto committee to investigate and overturn unwarranted slashing incidents, aiming to protect ethical validators and enhance overall security and trustworthiness.
