These data privacy regulations share common principles and grant similar rights to the data subject. For example, both GDPR and CCPA bear the rights to correct, update, or delete data on a business database and require businesses to obtain consent for certain collection, processing, transfer, or sale of personal data. Software solutions, including blockchain-based ones, must be built in a way that considers these issues. Scrutiny over the way organizations manage data privacy rights has never been higher. Regulators have full-bodied enforcement agendas; consumers across the globe are learning how they can take action to protect their own data privacy; and enterprises, large and small, are tackling the operational, technical, and reputational challenges for business-as-usual operations. In parallel, significant uncertainty remains in how these data privacy regulations apply to blockchain technology.
