The Masterclass will take the participants on a journey to build a custom application blockchain with the Cosmos SDK, deploy it and connect it via the Inter-Blockchain Communication (IBC) Protocol to Cardano. We demonstrate how to use the framework based on a case from the logistics space related to ship data processing. The Masterclass will explain the general flow of data but also go into details of the implementation and which steps are necessary to enable a Cosmos SDK chain to "talk" to Cardano.
