EigenLayer is a technical protocol created on Ethereum, which introduces the Restaking feature. As of June 5, 2024, over 5.309 million ETH have been restaked on the EigenLayer protocol.

Users holding ETH and users holding a certain type of liquidity asset related to ETH (LST) can both restake their assets on EigenLayer.

By restaking assets through EigenLayer, users can once again receive asset rewards, and developers can use the existing Ethereum validator set and staked ETH to launch new Actively Validated Services (AVS) - meaning that when developers want to build a new protocol on Ethereum, they no longer need to build security facilities and start a PoS network from scratch, effectively reducing the complexity of development.

EigenLayer founder Sreeram Kannan once said: "EigenLayer is the verifiable cloud of the encryption field." - and the technical core of the protocol that opens "cloud security verification" for the Web3 ecosystem is the aforementioned Actively Validated Services (AVS).

What are Actively Validated Services (AVS)?

Actively Validated Services (AVS) refers to any system that requires its own distributed verification semantics, such as side chains, data availability layers, virtual machines, Web3 Keeper networks, bridges, threshold encryption schemes, trusted execution environments, etc. Each Actively Validated Service (AVS) has a set of smart contracts.

Understanding EigenLayer's Actively Validated Services projects

On April 9, 2024, EigenLayer launched the operator and Actively Validated Services (AVS) modules on the mainnet. As of June 5, 2024, EigenLayer's official website has announced 13 online Actively Validated Services projects and 8 new type of Actively Validated Services projects based on Rollup, they are:

EigenDA

EigenDA landed on the mainnet in the second quarter of 2024, developed by EigenLabs, and is the first Actively Validated Services project on EigenLayer, which can also be tested and developed on the Holesky testnet.

Understanding EigenLayer's new type of Actively Validated Services project: Restaked Rollup

Restaked Rollup is a new category of EigenLayer's Actively Validated Services, which combines multiple services into a single Rollup service. Users can not only receive restaking rewards from the Restaked Rollup project, but also utilize multiple service functionalities at the same time.

AltLayer

Refer to the description in the previous "Actively Validated Services" section.
