# Implementing Federated Governance in Data Mesh Architecture +
## 7 Conclusions and Further Research  
To conclude, in this article, we presented a further improvement of the blockchain-based federated governance system in data mesh.  
First, we revisited and expanded the list of properties required for implementing efficient metadata and policy management. We provided an updated governance formal model that incorporates the utilization of data contracts, metadata, and product versioning.  
Second, we described how the integration of two open-source platforms - Hyperledger Fabric and Fybrik - can benefit organizations that need to focus on data privacy, compliance, optimized data usage, and policy-driven decisions.  
Third, we demonstrated a proof-of-concept system used to manage and govern data in cloud-native environments. It serves as a practical validation of the proposed multi-platform architecture for building the data mesh. We also presented a comparative study on other platforms aiming to build a data mesh governance and identified how our system satisfies the unaddressed issues.  
We envision future research in multiple directions. The first observation is that the existing data mesh proposals are focused on a single company platform and our current prototype is also built on a single Kubernetes cluster. Therefore, we aim to explore the scalability and efficiency of blockchain-based governance in multi-cluster environments, e.g., cross data mesh scenarios or decentralized data sharing and management in general.  
The second aspect is related to the limits of utilizing technology that affects the development of more sophisticated data contracts and policies, e.g., lack of support for
