zChain is designed to serve as a complement and extension to existing Blockchain systems, such as Ethereum, Cardano or Polkadot. zChain can be thought of as a local blockchain that runs on a Member’s device that is agent-centric, compared to existing blockchains where data is object-centric. Together, these two design patterns elegantly support the handling of local data, such as private messages and feed posts, and global data, such as namespaces and financial transactions, respectively.
