History

• Came out of Polygon (16-3-2023):

"Avail will be spun off completely from Polygon Labs. The Avail protocol co-creator Anurag Arjun, who has helmed the development of Avail from its inception, is moving out of Polygon Labs and will become Avail’s sole steward and will continue to lead the project in a separate, standalone and self-funded entity."

How it works

• From their X (26-2-2024):

"Avail is laying a foundation for a fundamentally integrated blockchain future where separate ecosystems can implement their own technology and scaling solutions while remaining connected via a trust-minimized and secure coordination layer.

Fusion Security enables additive crypto-economic security using asset classes other than the native Avail token (like BTC & ETH) to serve and secure the Avail network."

Staking

• From a thread on different DA layers (21-1-2024):

"Avail uses nominated proof of stake, and they support up to 1000 validators. They could remain operational even if the majority of full nodes went down, as they sample from their p2p network of light nodes."

Availability Layer

• From Onchain Times (19-3-2024):

"Avail DA is a data availability layer that implements data availability sampling (DAS) with validity proofs. the Avail DA layer offers cheap and secure data availability blobspace for rollups which allows these to access and post their large quantities of transactional data in a scalable manner. Unlike existing modular DAs that rely on an optimistic approach, Avail’s use of validity proofs enables 10x faster guarantees on transaction ordering resulting in a responsive experience for users. In its final form, Avail will have a peer-2-peer network consisting of multiple lightnodes it can sample data from. What makes Avail stand out is this ability which is unique for the Avail DA layer and results in an increasingly decentralized network."

Avail Fusion

• From Onchain Times (19-3-2024):

"Coordination of value across blockchains and rollups requires extensive shared economic security in the unification layer. This is what Avail Fusion Security provides.

Unification = modularity + aggregation + shared security

Fusion allows base-layer tokens like BTC, ETH, SOL and more to contribute to the Avail consensus in addition to $AVAIL. Rollups building on top of Avail are in addition able to help secure the Avail base layer with their own token. By allowing multiple different tokens to contribute to the security of Avail, the economic security has the potential to be magnitudes higher than other modular tech stacks."

Avail Nexus

• From Onchain Times (19-3-2024):

"Avail Nexus is a zk coordination rollup which consists of a proof aggregation/verification layer as well as a sequencer selection mechanism that is enabled by tapping into the Avail DA stack. Acting as a verification hub, rollups on top of the Nexus layer can communicate easily via a single proof verifying the state of all the other rollups."

Competition

• From a thread on different DA layers (21-1-2024):

"Avail uses the Grandpa + Babe Consensus inherited from Polkadot SDK, which has a slower block finality time compared to Tendermint. However, since Avail also uses KZG Commitments for validity proofs, they verify the accuracy of transactions faster than Celestia.

"Celestia and Avail use large blocks, data availability sampling, and light nodes to serve increasing demand. EigenDA uses DACs, which are also considered scalable, but more centralized."
