Avail, a mission 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 scale back prices for layer 2 and layer 3 chains within the Ethereum ecosystem.
Storing knowledge on Ethereum could be costly, so Avail goals to be an answer for layer 2s and 3s to publish knowledge off-chain, to scale back the excessive transaction charges that usually come from posting knowledge on the principle Ethereum blockchain. The thought is to spare the principle Ethereum blockchain from getting congested with something in addition to execution and settlement actions.
The problem of dealing with the info and establishing separate networks for knowledge storage is named the ”knowledge availability drawback,” or DA – an enviornment that features growing cryptographic techniques to show that the info exists (i.e. that it’s out there) and that it’s proper.
“The info attestation bridge establishes a direct connection between the L2 rollup’s knowledge and the L1 through Avail’s off-chain knowledge availability layer,” Avail stated in a press launch.
The bridge is one part of what Avail will supply within the layer 2 ecosystem. In the long run, Avail needs rollups to launch totally on prime of its community. These networks might embody 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 info attestation bridge offers the attestation on Ethereum,” Anurag Arjun, the founding father of Avail, advised CoinDesk. This then proves to Ethereum that “no matter knowledge was submitted by the rollup to Avail is definitely out there.”
