Data Availability support for Cartesi Rollups

That’s how I see it too! I read this proposal as “modular Data Availability support for Rollups”, in the sense that eventually alternative DAs could be added as “plugins”. As @felipeargento said, I believe the Dehashing Device is the key ingredient to make this available - but yes, for the foreseeable future there would need to be a specific dehashing plugin to fetch the data for each DA technology. Also, when fraud proofs are used, there will probably also be a need for some DA-specific code to resolve disputes about the data content.
