Avail, a project spun off from Polygon earlier this year to manage data storage and verification for blockchains, launched its “data attestation bridge” on Friday, a new offering designed to reduce costs for layer 2 chains and layer 3 in the Ethereum ecosystem.
Storing data on Ethereum can be expensive, so Avail aims to be a solution for layer 2 and 3 to publish data off-chain, to reduce the high transaction fees that often come from publishing data on the main Ethereum blockchain. The idea is to prevent the main Ethereum blockchain from being cluttered with anything other than execution and settlement activities.
The challenge of managing data and setting up separate networks for data storage is known as the “data availability problem” or DA – an area that includes the development of cryptographic systems to prove that data data exists (i.e. it is available) and is accurate. .
“The Data Attestation Bridge establishes a direct connection between L2 and L1 rollup data through Avail’s off-chain data availability layer,” Avail said in a press release.
The bridge is a component of what Avail will offer in the layer 2 ecosystem. Longer term, Avail wants rollups to be fully launched on its network. These networks could include so-called validiums, which are Ethereum scaling solutions that store transaction data off-chain.
“When an L3 or validium sends the transaction data to Avail, the data attestation bridge provides the attestation on Ethereum,” Anurag Arjun, the founder of Avail, told CoinDesk. This then proves to Ethereum that “all data submitted by the rollup to Avail is actually available”.
