Blockchain is a distributed ledger technology that has reliability in terms of maintaining data integrity and availability but not data privacy. Therefore, implementation of this particular unregulated technology must be reviewed to ensure compliance with relevant regulations, especially data privacy regulations which is this research main topic. For this reason, implementation of blockchain was observed in comparison with existing data privacy regulations in Indonesia. As initiation steps of research, data privacy regulations from Indonesia, Japan and Europe was used to be the input for the analysis of blockchain implementation. Two additionalinstruments, questionnaire and interview was used to produce an enhanced design for implementation of blockchain scheme in Indonesia. After the research was done, it was concluded that there is a possibility of blockchain implementation in Indonesia as long as the design was used with some notes as consideration.
