Avail offers to bridge the data availability gap for Ethereum rollups
Polygon spin-off Avail unveiled its data attestation bridge to Ethereum, Friday, as it seeks to carve out a niche in Ethereum’s rollup -centric scaling roadmap. Layer-2 rollups currently use Ethereum mainnet for posting their transaction data, which represents the majority of the transaction cost to users. These costs are expected to come down significantly following the next Ethereum upgrade “Dencun” later this year, which will implement EIP-4844. Further scaling gains should be found higher up the stack, on layer-3 networks envisioned such as Arbitrum Orbit, or zkSync’s hyperchains. That’s where Avail’s solution will likely come in, Anurag Arjun, Avail’s co-founder, told Blockworks in an interview. “With computation with something like [zero-knowledge proofs], you are able to compress proofs, you’re able to do recursive proofs and make it small, but with data, you cannot do it,” Arjun said. Right now, some early attempts make use of what are known as data avail ability committe...
