Avail, Spun Out of Polygon, Launches Data Attestation Bridge to Ethereum – Tokenoy

Avail, a mission spun out of Polygon earlier this yr to deal with information storage and verification for blockchains, launched its “data 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 information on Ethereum will be costly, so Avail goals to be an answer for layer 2s and 3s to publish information off-chain, to cut back the excessive transaction charges that usually come from posting information on the primary Ethereum blockchain. The concept is to spare the primary Ethereum blockchain from getting congested with something apart from execution and settlement actions.

The problem of dealing with the information and setting up separate networks for information storage is named the ”information availability drawback,” or DA – an enviornment that features creating cryptographic techniques to show that the information exists (i.e. that it’s out there) and that it’s proper.

“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 mentioned in a press launch.

The bridge is one part of what Avail will provide within the layer 2 ecosystem. In the long term, Avail needs rollups to launch totally on prime of its community. These networks may embrace so-called validiums, that are Ethereum scaling options that retailer transaction information 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 founding father of Avail, informed CoinDesk. This then proves to Ethereum that “whatever data was submitted by the rollup to Avail is actually available.”
