Regulating digital data privacy has become a concern in the Indonesian Legal System or the Pancasila Legal System. It is particularly important with regards to the data privacy in the block-chain technology. The block-chain technology has brought about positive development for businesses in Indonesia, but it also has negative impacts. Simultaneously, some said that there is no law governing this technology in the Indonesian System to control, particularly the aspects related to the data privacy. Therefore it appears that apart from the positive impacts of block-chain to improve the efficiency of time and transactions cost, on the other hand, block-chain gives opportunity to the beginning of cybercrime, i.e. data theft of the client’s financial data. This legal research has been conducted to examine norms, the laws and regulation on data privacy protection. It has been found that the accusation of many that there is no law governing the protection of the digital data, particularly aspects of block chain is not true. It has been found in examining the aspects of legal protection in the Indonesian Legal System that there is enough existing laws and delegated legislation provided for parties involve on the usage of block-chain to protect the transactions, particularly protecting the digital data privacy within the law.
