## Contribution

Introduces a novel blockchain-based publish/subscribe architecture using Hyperledger Fabric, enabling secure and decentralized digital asset trading.

## Key findings

- Effective implementation of a photo trading platform
- Demonstrates adaptability to various digital assets
- Validates blockchain-based pub/sub system performance

## Abstract

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.
