Regulatory compliance is another dimension of blockchain security. How do we ensure that the blockchain platform is GDPR-compliant? How do we ensure that the blockchain platform is compliant with the enterprise security policy? Such questions fall into the category of regulatory compliance-related security requirements. There are certain requirements around data localization, e.g., customer data may not leave a specific geographic location. In such scenarios, a globally replicated blockchain may not be the best solution. In those cases, restricted private transactions (introduced in Chapter 16, Enterprise Blockchain) could be a useful construct to follow. In other situations, the use of off-chain transaction managers located in specific geographic locations could be helpful.
