An Analysis of Blockchain and GDPR under the Data Lifecycle Perspective

The purpose of this article is to present an analysis of the privacy principles of personal data prescribed in the General Data Protection Regulation and the treatment of data in Blockchain technology in its primary version, guided by the phases of the Data LifeCycle. The Data Life Cycle presents the stages in which the data act in a given process and are related to each other, forming a chain of dependence between them. The General Data Protection Regulation, on the other hand, presents privacy principles that contemplate the necessary treatment for data at all stages of its life cycle. This analysis made it possible to identify the influence that the phases of the Data Lifecycle have on the adequacy of the principles of the General Data Protection Regulation and the treatment of the data performed on the Blockchain technology associated with the phases, presenting an approach to lead the process of adapting the technology to compliance with the legislation. In this context, some data treatment options were presented for the phases that presented gaps, making it possible to conclude that the result of this analysis can be used as a support tool to systematize the process of adapting to the law by organizations that use or intend to adopt Blockchain technology.
