In this article, we will introduce some of the most exciting AVS using EigenLayer in the staking pool.

AVS is a system that requires its own Decentralization validation, such as Sidechains, data availability layers or Oracle Machine. Using EigenLayer, these systems can leverage the security of Ethereum's Proof of Stake (PoS) to protect their services without requiring their own separate validators. This allows AVS systems to benefit from Ethereum's security while running their own Decentralization applications or services.

So what exactly is AVS? Here are some exciting AVS that I have been following:

EigenDA

EigenDA, developed by EigenLabs, is the first Active Verification Service (AVS) launched on EigenLayer. Its operation is similar to other Data Availability (DA) layers, such as Celestia or NearDA, and using EigenDA's Rollup can enjoy lower costs and higher throughput.

• In fact, Rollup integrated with EigenDA can increase throughput by 100 times, while operating costs drop 4 times.

Omini

As more and more Rollups are built on the Ethereum blockchain, the problem of liquidity fragmentation is becoming increasingly severe, leading to ecosystem isolation, inefficient transactions, and poor user experience. The Omni protocol aims to address these fragmentation challenges by enabling cross-Rollup communication, unifying liquidity pools, and simplifying user experience.

• Their OMNI Token is designed to serve as a universal transaction fee Token, making gas fee payments in rollups simpler. The Omni network is secured by staking ETH to increase security.

Witness Chain

In concept, Witness Chain is similar to Omni, aiming to unify isolated DEP economies by transforming physical attributes (such as location, computing power, network, storage, energy, etc.) into verified digital proofs.

• Their DePIN coordination layer has created a sharing economy for physical assets, allowing for cross-physical Supply Chain exchange of resources and information.
