Ethereum Scaling Solutions

Scalable data availability focused blockchain

A core component of the modular blockchain movement coming in the near future. Targeted towards off-chain scaling solutions and standalone chains.

Modular Blockchain Paradigm

Avail aims to facilitate a complete change in how we approach design of blockchain systems. Avail enables modular chain design where various execution environments can use Avail for data ordering and availability. Avail is agnostic to the execution layer, which can be the standalone chains or off-chain scaling solutions that use Avail. The applications hosted on these execution layers enjoy the full security of Avail.

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

  • Logo
    Every piece of data is erasure coded using polynomial interpolation
  • Logo
    Redundancy makes it harder to suppress data
  • Logo
    Light clients get ~100% confidence of data availability by performing constant number of queries

Low Resource Requirement

  • Logo
    Hosting a full node isn't needed to get availability guarantee
  • Logo
    Application clients can query data only relevant to application of their interest, without downloading the entire block
  • Logo
    System scales up as the number of users increases, increasing the availability of data

Polynomial Commitments

  • Logo
    Avail avoids fraud proofs using KZG polynomial commitments
  • Logo
    The data of each block is committed to the headers
  • Logo
    Light clients sample data and verify using commitment openings
  • Logo
    Batch openings help us optimize verification and proof size
