What are Actively Validated Services (AVS)

What are Actively Validated Services (AVS's)?

Actively Validated Services (AVS) are blockchain applications that operate outside the conventional Ethereum Virtual Machine (EVM), including L2 chains, data layers, sequencers, dApps, and cross-chain bridges. AVSs utilize their own decentralized consensus mechanisms independent of Ethereum's primary consensus layer. This independence allows them to tailor security and functionality specifically for their needs while still leveraging the broad validator network of Ethereum for enhanced security.

The creation of EigenLayer has been instrumental for AVSs, allowing them to leverage Ethereum’s robust validator set without needing their own consensus systems. This integration significantly enhances security and efficiency by connecting AVSs directly to Ethereum's established security infrastructure, effectively minimizing vulnerabilities associated with smaller, independent validator pools and stakes.

How Do AVS's Work with EigenLayer?

Actively Validated Services (AVS) efficiently integrate with Ethereum's established security protocol through the EigenLayer platform. Here’s a breakdown of their operation:

• Restaking via EigenLayer: AVSs employ the EigenLayer framework to restake Ethereum, which means they can benefit directly from Ethereum's formidable security features while operating their applications.
• Independent Transaction Validation: Though they work in Ethereum’s environment, AVSs continue to validate their transactions autonomously using consensus mechanisms like Proof-of-Work (PoW) or Proof-of-Stake (PoS), which allows them to remain decentralized.
• Role of Node Operators: Node operators in the AVS ecosystem contribute by restaking their Ethereum holdings on EigenLayer, securing AVS transactions. This activity earns them additional rewards atop what they garner from standard Ethereum operations.
• Security and Cost Benefits: By interfacing directly with Ethereum through EigenLayer, AVSs circumvent the complexities and expenses typically associated with setting up independent consensus mechanisms. This linkage also significantly shores up their defense against potential security breaches.

Using EigenLayer, AVSs achieve a synergistic balance: they gain access to Ethereum's strong security layers while maintaining their distinct operational frameworks and economic models.

Most Popular Actively Validated Services

The leading Actively Validated Services (AVSs) on the EigenLayer platform demonstrate a diverse set of functionalities, particularly in security and decentralized operations. Here’s a concise overview of some prominent AVSs:

• EigenDA: A pioneering AVS for data availability, EigenDA enhances throughput and security. It utilizes a network of node operators who stake in the system, driving economic incentives for robust data layers, thereby improving efficiency and cost-effectiveness for rollups.
• AltLayer: This service introduces 'Restaked rollups,' merging simple rollup deployments with the robust security features of EigenLayer. It focuses on app-specific segments, providing them with secure, rapid deployment solutions essential for latency-sensitive applications like games.
• Ethos: Expanding Ethereum’s security to the Cosmos ecosystem, Ethos uses a layered approach to allow decentralized chains to tap into Ethereum’s established security via restaked ETH.
• Lagrange: Specializing in verifiable computations, Lagrange fortifies data integrity and scalability for smart contracts through Zero-Knowledge proofs, enhancing secure off-chain interactions.
• Drosera: Focused on security, Drosera allows protocols to autonomously monitor and respond to threats through its innovative "Trap" system, which enables decentralized, condition-based responses.

These services are exemplary in their use of the EigenLayer platform to boost both the functionality and integration of blockchain applications across various ecosystems. You can find a full list of live AVS providers on the ethrestaking platform.
