Those aspects are peer network, smart contracts, membership, events, ledger, system integration, wallet, and system management. All listed components can be part of a digital public service enhancing trustability and enabling interoperability in a secure and reliable way. Additional information: In the creation of the Blockchain component, several actors such as developer, user, architect, regulator, operator, membership services, etc. are present in a blockchain that provides a solution to a blockchain-based business network. Each actor and component present in a blockchain plays a major role to make the network more secure and reliable.
