Main achievement: Development of the first blockchain ecosystem for space system engineering, as a global configuration tool that can model the business logic of concurrent design. Addressing the MBSE challenges of  controlling data exchange and traceability across system development and operations lifecycle.

Results: Two use cases have been successfully implemented

• A decentralized identification system that enables LSIs and contractors to generate sub-identifications for their personnel. Keeping a great granularity of information on the audit trail and enabling to reach feedback from the right person at the right time

• Implementation of a Zero Knowledge Proof (ZKP) protocol within the blockchain system to demonstrate the use of ZKPs in concurrent engineering for mass budget verification (where the mass value of a component cannot be disclosed)

Next steps: further development and adaptations of the decentralised Exochain system is undergoing with a recent awarded ESA research contract under the OSIP campaign “Cognitive Cloud Computing” by the title “Blockchain ecosystem for an autonomous consensus mechanism of federated satellite networks”
