Polygon's modular blockchain project Avail has launched the "Data Proof Bridge"

ChainCatcher news, according to CoinDesk, Polygon's modular blockchain project Avail has launched a "data attestation bridge," aimed at reducing costs between Ethereum Layer 2 and Layer 3, helping to ensure the security of off-chain data.

The "data attestation bridge" connects to Ethereum and can be used by ZK Rollups and Optimistic Rollups that utilize Ethereum as the base layer. This data attestation bridge establishes a connection between L2 Rollup data and L1 through Avail's off-chain data availability layer. (Source link)
