2.4.2. Data integrity verification enabler

2.4.2.1. Introduction 

This is an enabler responsible for providing DLT-based data integrity verification mechanisms that allow data consumers to verify the integrity of any data at question.

Network peers host smart con-tract (chaincode) which includes the data integrity business logic. It stores hashed data in a data structure and it compares it with the hashed data of the queries made by clients in order to verify their integrity.

2.4.2.3. Place in architecture 

The Integrity Verification enabler is part of the vertical plane DLT enablers.

2.4.2.4. User guide 

The user guide will be determined after the release of the enabler.

2.4.2.5. Prerequisites 

Hyperledger Fabric 2.2, Hyperledger Fabric CA 1.4

2.4.2.6. Installation 

The installation procedure is under development.

2.4.2.7. Configuration options 

The enabler is prepared to run in a K8S environment. The creation is prepared to be autonomous in such a working environment. The service consumer will be required to communicate with the server using the described Rest interface.

2.4.2.8. Developer guide 

The Integrity Verification enabler is build using Hyperledger Fabric Framework. Smart contracts are written in Go.

2.4.2.9. Version control and release 

Gitlab will be used as a version control and release tool.

2.4.2.10. License 

Will be determined after the release of the enabler.

2.4.2.11. Notice(dependencies)

Dependency list and licensing information will be provided
