Challenge

Rollups face the problems of insufficient throughput or weak security with existing data availability solutions. They needed to build a scalable data availability layer for rollups while making it accessible and easy for them to verify.

Solution

Celestia provides a data availability layer that scales with the number of users while enabling rollups to verify data availability with just a light node. Opting to use the interchain stack, including CometBFT and IBC, provided Celestia with a state machine, consensus network, and interoperability out-of-the-box.
