The Hyperledger Quilt already enables a specific type of blockchain interoperability using the Interledger Protocol, i.e., allows payments to across any payment network using the Interledger protocol. A relatively recent Hyperledger Lab, “Hyperledger Labs Blockchain Integration Framework” is creating a communication model to enable permissioned blockchain ecosystems to exchange on-chain data or custom assets independent independently of the platform (e.g., Hyperledger Fabric, Quorum, etc.).
Nevertheless, to the best of our knowledge, no Hyperledger project is tackling general blockchain interoperability for both public and private blockchains or studying the impact of blockchain interoperability, particularly on the Hyperledger ecosystem.

What is this project about?
This project intends to propose a solution to this real-world problem, and it is research-focused. The goal is to give a strong contribution to the Hyperledger ecosystem in terms of the state of the art in blockchain interoperability. Some questions that this project aims to answer are:
- How can we interoperate Hyperledger technologies with other blockchains?,
- How can Hyperledger initiatives position themselves to tackle blockchain interoperability?,
...
- What standards we require to define middleware between blockchains?
...
- What are the consequences of employing smart contracts with external processes and data (the external part means another connected blockchain)?,
...
- The key to the survivability of this technology?
In other to try to answer those questions, in this project the mentee(s) will start by studying some of the most prominent blockchain interoperability solutions already available or being proposed, and how they can be used to promote and strengthen Hyperledger technologies. Then, the mentee will design and develop a framework for creating, deploying and maintaining services with several blockchains. The applicability of the solution to be proposed is to be demonstrated through the exploration of a use case, implementing several blockchains (including Hyperledger Fabric) to increase the dependability of blockchain-powered services administrated by several stakeholders, serving as a proof-of-concept.

The Use Case: Digital Media dApp
The scenario corresponds to a decentralized ecosystem for Digital Media contents, that empowers the creators of those contents and delivers to consumers a diverse collection of classic and original contents.
That ecosystem is based on an artist-centric model, in which the creators are paid fairly for their contents (music, video, images, texts…), and their fans consume, share and enjoy what they like, and pay fair value. This model considers that publishers, labels or digital distributors are equal to creators, rather than dominant members of the ecosystem.
The This dApp concept aims to demonstrate a hypothetical solution to help artists monetize their work in a transparent and secure peer-to-peer marketplace by implementing and enabling interoperable blockchains throughout the whole Digital Media production, distribution, and management processprocesses, ensuring that their the artist work is correctly recorded (including rights management and tracking) and that they receive fair royalty payments (through the use of smart contracts and cryptocurrencies).
