Blockchain-based Record Keeping System for Building Permit Issuance

The used of centralized system in government are common nowadays. However, by using the centralized database, only one authority that has the system can do everything to the the system. This aspect of centralized system can lead to collusion with the government officials or middleman in the process of issuing building permit. In this paper, we propose a blockchain based system to record all the transactions in the process of issuing a building permit. The purpose is to increase the transparency, data integrity and make it easier to track the transactions with the feature in blockchain. We use a case study of the building permit issuance process in one stop-service local government office in Jakarta. After knowing the process, we determine the participant, asset, transaction and access control of participant in the blockchain system.
