A Complete Guide to EigenLayer: The Verifiable Cloud for Web3

EigenLayer has emerged as a groundbreaking development in blockchain technology — a restaking protocol for Ethereum positioned as the verifiable cloud for web3. It allows Ethereum validators to leverage their staked ETH to secure additional services for additional rewards, creating a shared layer of pooled security that benefits dapps, middleware modules, and chain layers with enhanced security and decentralized trust.

One of the most exciting aspects of EigenLayer is its model for Actively Validated Services (AVS). These blockchain-based systems use EigenLayer’s restaking mechanism to implement unique validation methods across the Ethereum network, rapidly bootstrapping new solutions that cater to applications and rollups.

Just as cloud computing revolutionized web2 development by providing scalable, on-demand infrastructure, EigenLayer is set to transform web3 by establishing a new paradigm for security, scalability, and interoperability. As EigenLayer founder Sreeram Kannan recently put it, “Ethereum is the verifiable internet. Rollup is the verifiable web server. AVS is verifiable SaaS. EigenLayer is the verifiable cloud.”

The EigenLayer Vision

EigenLayer is a decentralized, trustless infrastructure layer that introduces a novel restaking mechanism for staked ETH. This extends Ethereum’s security to a wide range of blockchain applications and services while optimizing resource utilization. The protocol involves four key players:

Restakers: Individuals or entities that stake ETH or LSTs through EigenLayer.
Operators: Operators run specialized node software and perform validation tasks for AVSs. They register with EigenLayer, receive delegated stakes from restakers, and earn rewards for their services.
AVSs: Actively Validated Services are decentralized services and infrastructure modules that run on EigenLayer, leveraging its pooled security.
AVS Users: End-users or applications that interact with the AVSs.

Restakers can participate in EigenLayer via two options:

Native Restaking: Ethereum validators can operate their own node and deposit regular ETH into an EigenPod, providing direct security contributions to EigenLayer.
Liquid Restaking: Users can deposit liquid staking tokens (LSTs) like Coinbase’s cbETH, Rocket Pool’s rETH, or Lido’s stETH directly into EigenLayer.

Restakers can delegate their staked ETH or LSTs to operators, who aim to maximize value for delegators by supporting various AVSs like Ava Protocol. This approach ensures broad participation and flexibility within EigenLayer, promoting permissionless innovation while addressing several critical challenges for web3:

Fragmented Security: Blockchain projects can struggle to create their own security from scratch, which is typically costly and time-intensive.
Limited Scalability: Infrastructure constraints limit the growth of dapps and services, keeping them from reaching their full potential.
Development Bottlenecks: The high cost and complexity of launching on-chain projects slows innovation and discourages teams from entering the space.

By reutilizing Ethereum’s validator network, EigenLayer provides a solution that opens a new era of blockchain development and adoption.

Security and Risk Management

EigenLayer implements rigorous security measures to protect against malicious behavior, safeguarding integrity and trustworthiness:

Slashing Conditions: Up to 100% of staked ETH can be slashed for malicious behavior, significantly raising the cost of attacks and deterring potential bad actors.
Cryptoeconomic Security: EigenLayer increases the overall cost of corruption by pooling security across multiple services, making it more difficult and expensive for attackers to exploit the system.
Risk Management: Protocol mechanisms monitor the risk of operator collusion as well as unintended slashing events, protecting the interests of all participants.

EigenLayer’s architecture combines on-chain and off-chain elements to optimize performance and security:

Smart Contracts: On-chain contracts manage slashing and payments, ensuring transparency and accountability.
Off-Chain Containers: Specialized software handles the execution of specific tasks that don’t need to be processed directly on the blockchain, enhancing scalability and flexibility.

Operator Delegation

EigenLayer operators play a crucial role. They receive delegated stakes, deposit them to spin up new Ethereum validator nodes, and subject the stakes to slashing conditions from the modules they participate in.

Delegation and operator management is coordinated by a structured system that maintains efficient and transparent governance:

Operator Registration: Operators must register with EigenLayer’s DelegationManager contract to provide services, ensuring they meet the necessary requirements and standards.
Delegation Process: Restakers delegate their ETH or LSTs to operators running specialized node software, enabling them to earn rewards without directly managing the technical aspects of validation.
Free-Market Governance: An open marketplace allows operators to choose which services to support based on risk and reward, fostering a competitive and dynamic ecosystem.

Actively Validated Services

AVSs are analogous to software-as-a-service (SaaS) for web3, providing specialized, verifiable functions that serve rollups and dapps. Ava Protocol, for example, is an AVS that enables event-driven automation for smart contracts.

AVSs operate beyond the Ethereum Virtual Machine’s limitations, supporting new functionalities. They can support decentralized services like identity verification, two-factor authentication, and more, extending capabilities and trust.

Example AVS types include:

Data Availability Layers: Improve data storage and retrieval, ensuring high availability and reliability.
Oracle Networks: Provide secure and reliable external data to smart contracts.
Bridges and Cross-Chain Solutions: Support cross-chain interoperability by simplifying complex workflows.

Rollups: Verifiable Web Servers

Rollups serve as verifiable web servers that leverage Ethereum’s trust model. They augment Ethereum’s capabilities by handling transactions off-chain and then rolling them up into a single transaction on-chain, improving scalability and efficiency.

The interplay between rollups and AVSs creates a cohesive support network for decentralized applications, where various services can seamlessly interact and complement each other.

Emerging Trends and Applications

EigenLayer makes exciting new opportunities for innovation and development in the blockchain space possible, such as:
