LFX Mentorship Showcase 2023

The number of projects focused on Central Bank Digital Currencies has been increasing at a fast pace. As it is important to correctly manage a digital form of money in a core CBDC ledger, one must also provide a way for retail businesses, in other ledgers, to use this money. Therefore, interoperability between a permissioned consortia ledger (e.g. Hyperledger Fabric) and others that offer different services such as retail businesses (e.g. EVM-based chains) is needed. We implement a bridge between Hyperledger Fabric and Hyperledger Besu, using the ODAP business logic plugin in Hyperledger Cacti. ODAP is an asset transfer protocol under specification in the Internet Engineering Task Force. To make this project a reality, André worked closely with his mentors László Gönczy and Imre Kocsis, to brush up on his research and development skills. In the initial phase, they conducted research on interoperability solutions, followed by an implementation of the use case. The latter required the development of chaincode and smart contracts in solidity. This work was also largely possible due to the collaboration with the Hyperledger Cacti community.
