Work Package 4
Decentralised architecture for secure and interoperable exchange of DCCs
WP4 develops an EBSI-based decentralised architecture for data immutability and self-sovereign identities — the first application of EBSI in metrology. It integrates this trust layer with the project's digital workflows and DCCs, enabling universally accepted, verifiable calibration certificates across Europe in line with FAIR principles, Digital SI, and the eIDAS ecosystem.
