Data Availability Solved
Avail is a modular blockchain that records transaction data for other blockchains so they don’t have to. Testnet live now.
Overview
Modular Blockchains Evolved
We’ve been asking blockchains to do a lot. Avail takes the data availability part off their plate. Any execution environment can use Avail for data ordering and availability. That includes standalone chains, off-chain scaling solutions, and any other type of execution environment. The applications hosted on these execution layers enjoy the full security of Avail from day one. No more bootstrapping validator sets. No more tokenomics.
Architecture
Decoupling execution from data availability
Off-chain scaling solutions can unlock their full potential by offloading data availability to Avail. Standalone chains can bootstrap validator security by using Avail for data availability.
Data Redundancy
- Every piece of data is erasure coded using polynomial interpolation
- Redundancy makes it harder to suppress data
- Light clients get ~100% confidence of data availability by performing constant number of queries
Low Resource Requirement
- Hosting a full node isn't needed to get availability guarantee
- Application clients can query data only relevant to application of their interest, without downloading the entire block
- System scales up as the number of users increases, increasing the availability of data
Polynomial Commitments
- Avail avoids fraud proofs using KZG polynomial commitments
- The data of each block is committed to the headers
- Light clients sample data and verify using commitment openings
- Batch openings help us optimize verification and proof size
