Avail, a modular project dedicated to integrating all Web3 users and developers through a "unification layer", announced today the launch of the Avail DA mainnet and the AVAIL token. The launch of Avail DA is the first step in Avail's vision to provide developers with the necessary tools to enhance blockchain scalability, improve liquidity, and provide seamless usability across different blockchain ecosystems.

Avail DA is a modular blockchain solution designed to optimize data availability (DA) services for highly scalable and customizable Rollups. Avail DA is the only chain-agnostic DA layer that combines KZG commitments and data availability sampling (DAS). This is a major milestone in the history of blockchain development, allowing Rollups to immediately enjoy the features and benefits of the Ethereum danksharding roadmap.

Avail's light client uses proof of validity to efficiently verify data availability and can be integrated into consumer hardware such as mobile phones. The combination of DAS and proof of validity enables faster DA verification, allowing data to be sampled immediately after Avail's verification node completes block confirmation. In order to reduce the centralization risk of verification nodes, Avail adopts a "Nominated Proof of Stake" (NPoS) consensus mechanism that evenly distributes staked tokens among active verification nodes. Avail DA's decentralized verification node cluster is initially designed to support 1,000 nodes and can grow to 10,000 nodes over time.

“By combining KZG commitments with DAS, we will provide a more advanced data availability infrastructure for today’s blockchain ecosystem,” said Prabal Banerjee, co-founder of Avail. “With just a few lines of code, developers can connect any execution environment with Avail DA to build a more powerful blockchain.”

Joey Krug, partner at Founders Fund, said: "The cryptocurrency industry is moving towards modularity, the demand for interoperability is increasing, and Avail is building critical infrastructure to advance this trend. Their architecture leverages KZG proofs and DAS to achieve impressive speed and security, as well as being fully chain-agnostic. We are pleased to support the Avail team and their significant and rapid progress in achieving this vision."

At the same time as Avail DA goes live, the AVAIL token will also be launched. As the native asset of the Avail network, AVAIL will be used to pay DA fees and ensure network security through staking . Starting today, AVAIL holders can start staking their AVAIL on staking.avail.tools , giving them the opportunity to participate in the maintenance of network security and help the ecosystem achieve incentive consistency.

Anurag Arjun, co-founder of Avail, said: “Avail DA and AVAIL represent the culmination of years of research and development to address a number of key challenges currently facing the Web3 industry, such as blockchain fragmentation, insufficient data availability, and scalability limitations. It is the cornerstone of the future development of the blockchain industry, enabling the entire ecosystem to work seamlessly together. We are excited to see the innovative solutions that partners and developers build on Avail.”

Avail DA supports multiple blockchain architectures including Validium, Optimism, Sovereign Rollup, and BTC L2. The network has reached partnerships with more than 70 partners , including specific application chains, DeFi chains, and Web3 game chains, which will be integrated with Avail DA at launch or soon. In addition, Avail has also integrated with mainstream Ethereum L2 solutions and Rollup frameworks including Arbitrum Orbit, Optimism OP Stack, Starkware, Polygon CDK, and ZKsync.

The Avail team is excited to share the launch of Avail DA with the ecosystem and welcomes community partners to build with Avail. Avail is currently moving towards the next two major versions, Avail Nexus and Avail Fusion. Avail Nexus is an interoperability layer that provides convenient and powerful proof aggregation, and supports ZK rollup for sequencer selection on top of Avail, allowing cross-Rollup and cross-ecosystem settlement; Avail Fusion, as a secure network layer, can provide additional cryptoeconomic security through re-staking, thereby completing the construction of a "unified layer".

Avail has raised a total of $75 million in funding and is backed by investors including Founders Fund, Dragonfly Capital and Cyber Capital.

About Avail

Avail, led by former Polygon co-founder Anurag Arjun, is building a "unified layer" to solve Rollup fragmentation. Avail will solve blockchain scalability issues from first principles: Avail DA is a data availability layer that uses technologies planned in the Ethereum danksharding roadmap, such as KZG commitments and DAS; Avail Nexus solves the growing fragmentation problem by using proof aggregation on Avail DA to achieve permissionless interoperability; Avail Fusion further strengthens Avail's security through multi-asset re-staking.
