Avail is working with StarkWare to enhance data availability based on validity-driven application chains in Starknet Layer 2 networks.
This data availability solution will be integrated into the Starknet application chain developed using Madara, a customizable sequencer. These application chains will run as "Layer 3" in the Starknet ecosystem.
According to a statement, Layer 3 will be able to leverage Avail in multiple modes for data availability services. These modes include validity and sovereign rollup, each offering unique benefits in terms of transaction processing efficiency and certainty. These infrastructures will be available to the Madara chain following the planned mainnet launch in the first quarter of 2024. Currently, developers can begin experimenting with Madara’s data availability interface on the testnet. (The Block)
