Challenge of choice - Explain the challenge of choice

Traceability and Transparency

The potential blockchain solution is proposed, To introduce Traceability and Transparency, to improve Integrity and making it Seamless. For Prototype, we have focused our work on the first four steps of Maintenance Scenario, in the future, we will be focusing on the next 12 steps. This Planned protocol will be able to reduce the complete process time period by 33% with enabled blockchain security. The solution doesn't use any 3rd party involvement. This Solution is developed by keeping in mind the generic implementation and replaces the physical documents with a consortium blockchain ledger.
