EigenLayer is a technical protocol created on Ethereum that introduces the restaking function. As of June 5, 2024, more than 5.309 million ETH have been re-staked on the EigenLayer protocol.
Users who hold ETH and users who hold a certain type of liquid asset (LST) related to ETH can re-pledge their assets on EigenLayer.
By re-staking assets through EigenLayer, users can once again receive asset rewards, and developers can leverage Ethereum’s existing validator set and staked ETH to launch new Actively Validated Services (AVS) — this means that when developers want to build a new protocol on Ethereum, they no longer need to build security facilities and launch a PoS network from scratch, effectively reducing development complexity.
Sreeram Kannan, founder of EigenLayer, once said: "EigenLayer is a verifiable cloud in the field of encryption." - The core technology of this "cloud security verification" protocol that opens up the Web3 ecosystem is the "Active Verification Service (AVS)" mentioned above.
What is Active Authentication Service (AVS)?
Active Verification Service (AVS) refers to any system that requires its own distributed verification semantics for verification, such as side chains, data availability layers, virtual machines, Web3 Keeper networks, bridges, threshold encryption schemes, trusted execution environments, etc. Each Active Verification Service (AVS) has a set of smart contracts.

Learn about EigenLayer's Active Verification Service
On April 9, 2024, EigenLayer launched the operator and active verification service (AVS) module on the mainnet. As of June 5, 2024, EigenLayer’s official website announced 13 active verification service projects that have been launched and 8 new active verification service projects based on Rollup. They are:
EigenDA
EigenDA has been launched on the mainnet in the second quarter of 2024. It is developed by EigenLabs and is the first active verification service project on EigenLayer. It can also be tested and developed on the Holesky testnet.

Learn about EigenLayer’s new active verification service: Restaked Rollup
Restaked Rollup is a new category of EigenLayer's active verification service. It merges multiple services into a single Rollup service. Users can not only obtain re-staking income from the Restaked Rollup project, but also use multiple service functions at the same time.
