The Citizen Data Network allows your applications to leverage PPK and P2P blockchains for user-centric data security. Public-Private Keys are used to ensure that every data transaction is signed and users only share data when and to whom they approve. Peer-to-Peer Blockchains are used to ensure that all atomic data transactions are verified and immutable. Additional network features ensure security, integrity and performance while reducing complexity for your developers. Integrate Your Applications to Blockchain Data Storage. The Citizen Data Network provides web and mobile software development kits (SDKs) and a worldwide connection layer that makes it easy for you to integrate your applications to blockchain-based data storage. The network allows you to leverage public or permissioned blockchains and to manage your own application-specific blockchains in AWS or Azure.
