HyperPubSub: Blockchain based Publish/Subscribe
This addresses the need for secure and decentralized publish/subscribe systems in digital asset trading, but it is incremental as it applies an existing blockchain to a known problem.
The authors tackled the problem of implementing a publish/subscribe system by using a private blockchain (Hyperledger Fabric) as the broker, and demonstrated its effectiveness through a photo trading platform, showing it can be adapted for any digital asset trading.
In this paper we describe the architecture and the implementation of a broker based publish/subscribe system where the broker role is played by a private blockchain, Hy-perledger Fabric. We show the effectiveness of our architecture by implementing and deploying a photo trading plateform. Interestingly, our architecture is generic enough to be adapted to any digital asset trading.
