    Manage accounts

    You can create, view, freeze, and unfreeze blockchain accounts in Ant Blockchain. If any illicit content is found on an account, the administrator can freeze this account. A frozen account can no longer join a consortium, and its applied certificate on the consortium chain will also be revoked.

    Note: The BaaS platform will not save the private key for you. You must save the private key by yourself and ensure its confidentiality.

    Manage nodes

    You can view the information of all nodes in the current blockchain, including the node IP address, service port, and the consensus status.
