Avail, a blockchain project known for its data availability network, announced Tuesday that it has raised $43 million in a Series A funding round, bringing the total funding secured to $75 million. This news comes after Avail, which spun out of Polygon in March 2023, shared it had raised $27 million in seed funding three months ago.

Avail is a Web3 infrastructure layer that allows modular execution layers to scale and interoperate with minimal trust.

Data availability networks like Avail enable blockchains to store information cheaply and in an easy-to-reference manner. The tech is particularly useful in the context of blockchain scaling, helping layer-2 "rollup" networks manage transaction data and other information without relying on the main blockchain layer. This offloading reduces the pressure on the main chain, leading to lower costs for end-users.

Avail can help reduce gas fees tremendously and scale transactions beyond existing limits, pushing blockchain networks toward Web2-like efficiency. Avail is addressing the gap in Web3 efficiency as it is a long way behind what Web2 provides.

Avail’s Unification Layer

Avail DA is the essential next step in a three-phase plan to provide an infrastructure layer to accelerate the unification of web3. Nexus is second, addressing cross-chain composability and responsive asynchronous messaging. Third, Fusion Security provides strong, shared economic security.

We're looking forward to accelerating our vision of building the Unification Layer.

The Unification Layer consists of:

1. Avail DA - The base data availability layer that provides core infrastructure allowing networks of blockchains built on top to scale efficiently.

2. Avail Nexus - A proof aggregation and sequencer selection ZK rollup on top of Avail DA, allowing for cross-rollup and cross-ecosystem settlement.

3. Avail Fusion - A crypto-economic security layer secured by multiple assets such as BTC and ETH.

Conclusion

The Avail ecosystem is set to be a unifying force for the rollup-centric world. They do this by building unifying experiences—composing interactions across chains, aggregating cryptographic proofs across ecosystems, or fusing shared security guarantees across value layers.
