TechFlow news: Avail, a modular blockchain project spun off from Polygon, has launched its "data attestation bridge," a new product designed to reduce costs for Ethereum Layer 2 and Layer 3 chains while helping secure off-chain data.
The "data attestation bridge" connects to Ethereum and can be used by ZK Rollups and Optimistic Rollups that use Ethereum as their base layer. This data attestation bridge establishes a connection between L2 Rollup data and L1 through Avail's off-chain data availability layer.
