Every user who joins the Dimension ecosystem will acquire a unique digital identity, just like a real-world ID, and with this digital identity, we can With this digital identity, we can circulate freely within the DimensionChain ecology-related applications. Dimension Digital Identity System provides an easy-to-use, secure and fault-tolerant solution to solve users' private key management problem, public chain silo effect problem, etc., break the barrier between public chains, realize chain-chain interoperability and interconnection of all things. For example, each meta-universe project is running independently and distributed on different public chains, even two projects on the same public chain do not intersect with each other, but the Dimension Digital Identity System can not only realize the interoperability between projects on the same public chain, but also realize the interaction and integration between multiple public chains, truly breaking the information gap and realizing the ecological integration.
