Conducting Privacy Impact Assessments (PIAs) prior to deploying new features or updates in blockchain systems is essential for identifying and mitigating potential privacy risks. PIAs involve systematically evaluating how proposed changes may affect individual privacy, enabling organizations to implement necessary safeguards in compliance with data protection regulations. In the context of blockchain technology, several studies have explored frameworks and methodologies to assess and enhance privacy protections. For instance, a comprehensive survey titled “A Survey of Blockchain-Based Privacy Applications” examines various tools and techniques for protecting privacy within blockchain-based systems, highlighting the importance of incorporating privacy assessments in the development process.
