Avail, Spun Out of Polygon, Launches Data Attestation Bridge to Ethereum
The move represents a step forward in Avail's plan to help secondary networks in the Ethereum ecosystem to speed up their processing – by giving them an alternate way to store the data, and verify its existence and availability, besides storing it on the main blockchain.
Avail, a project spun out of Polygon earlier this year to handle data storage and verification for blockchains, launched its "data attestation bridge" on Friday, a new offering designed to reduce costs for and layer 3 chains in the Ethereum ecosystem.
The data attestation bridge helps secure data off-chain. It’s connected to Ethereum, and can be used by both that use Ethereum as a base layer.
Storing data on Ethereum can be expensive, so Avail aims to be a solution for layer 2s and 3s to publish data off-chain, to reduce the high transaction fees that often come from posting data on the main Ethereum blockchain. The idea is to spare the main Ethereum blockchain from getting congested with anything besides execution and settlement activities.
The challenge of handling the data and setting up separate networks for data storage is known as the ”data availability problem,” or DA – an arena that includes developing cryptographic systems to prove that the data exists (i.e. that it's available) and that it’s right.
“The data attestation bridge establishes a direct connection between the L2 rollup’s data and the L1 via Avail’s off-chain data availability layer,” Avail said in a press release.
The bridge is one component of what Avail will offer in the layer 2 ecosystem. In the longer term, Avail wants rollups to launch entirely on top of its network. These networks could include so-called , which are Ethereum scaling solutions that store transaction data off-chain.
“When an L3 or a 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 “whatever data was submitted by the rollup to Avail is actually available.”
In March, Avail , where Arjun had been a co-founder. In June, Avail , where it went through a series of tests to encourage validator participation in the network.
