Avail, a project spun out of Polygon earlier this year to handle blockchain data storage and validation, announced Friday that it has launched a new project designed to reduce the cost of Layer 2 and Layer 3 chains in the Ethereum ecosystem. The service “Data Authentication Bridge'' has been launched.
Storing data on Ethereum can be expensive, so Avail allows layers 2 and 3 to expose data off-chain and avoid the high-value transactions that occur by posting data to the main Ethereum blockchain. We aim to be a solution to reduce fees. The idea is to ensure that the main Ethereum blockchain is not congested with anything other than execution and payment activity.
The challenge of processing data and setting up separate networks for data storage is known as the “data availability problem” (DA). This is a field that involves the development of cryptographic systems to prove that data exists (that is, it is available) and that it is correct. .
“The data authentication bridge establishes a direct connection between the data in the L2 rollup and L1 through Avail’s off-chain data availability layer,” Avail said in a press release.
Bridges are one of the components that Avail provides in the Layer 2 ecosystem. In the long term, Avail hopes to launch rollups entirely on its own network. These networks are likely to include so-called Validium, an Ethereum scaling solution that stores transaction data off-chain.
“When L3 or Validium sends transaction data to Avail, the data authentication bridge provides authentication on Ethereum,” Avail founder Anurag Arjun told CoinDesk. This proves to Ethereum that “all data sent to Avail by the rollup is, in fact, available.”
