Avail, Spun Out of Polygon, Launches Knowledge Attestation Bridge to Ethereum

Avail, a challenge spun out of Polygon earlier this 12 months to deal with knowledge storage and verification for blockchains, launched its “knowledge attestation bridge” on Friday, a brand new providing designed to cut back prices for layer 2 and layer 3 chains within the Ethereum ecosystem.

Storing knowledge on Ethereum may be costly, so Avail goals to be an answer for layer 2s and 3s to publish knowledge off-chain, to cut back the excessive transaction charges that always come from posting knowledge on the principle Ethereum blockchain. The concept is to spare the principle Ethereum blockchain from getting congested with something apart from execution and settlement actions.

The problem of dealing with the information and establishing separate networks for knowledge storage is called the ”knowledge availability downside,” or DA – an enviornment that features growing cryptographic programs to show that the information exists (i.e. that it’s accessible) and that it’s proper.

“The information attestation bridge establishes a direct connection between the L2 rollup’s knowledge and the L1 by way of Avail’s off-chain knowledge availability layer,” Avail stated in a press launch.

The bridge is one element of what Avail will provide within the layer 2 ecosystem. In the long term, Avail desires rollups to launch solely on prime of its community. These networks might embrace so-called validiums, that are Ethereum scaling options that retailer transaction knowledge off-chain.

“When an L3 or a validium sends the transaction knowledge to Avail, the information attestation bridge offers the attestation on Ethereum,” Anurag Arjun, the founding father of Avail, instructed CoinDesk. This then proves to Ethereum that “no matter knowledge was submitted by the rollup to Avail is definitely accessible.”
