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 will 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 always come from posting knowledge on the principle Ethereum blockchain. The thought is to spare the principle Ethereum blockchain from getting congested with something moreover execution and settlement actions.
The problem of dealing with the information and organising separate networks for knowledge storage is called the ”knowledge availability downside,” or DA – an enviornment that features creating cryptographic techniques 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 through Avail’s off-chain knowledge availability layer,” Avail mentioned 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 completely on high 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 information attestation bridge gives the attestation on Ethereum,” Anurag Arjun, the founding father of Avail, informed CoinDesk. This then proves to Ethereum that “no matter knowledge was submitted by the rollup to Avail is definitely accessible.”
