Avail is a modular data availability blockchain built to serve as the foundational data layer for rollups, validiums, and sovereign blockchains. Originally developed by former Polygon team members, Avail spun out as an independent project in 2023 and launched its mainnet and AVAIL token in 2024.

The Data Availability Problem
Rollups scale Ethereum by executing transactions offchain and posting only compressed data to Ethereum for verification. The expensive part is data availability — ensuring transaction data is published somewhere that anyone can verify.
Avail offers a cheaper, scalable DA layer:
- Erasure coding: Data is encoded so it can be reconstructed even if some validators go offline
- KZG polynomial commitments: Cryptographic proof that data was correctly published
- Data Availability Sampling (DAS): Light clients verify DA by sampling small random chunks
This means rollups using Avail pay a fraction of what Ethereum DA costs.
