1. A method, comprising:
generating a data confidence fabric billing manifest;
rendering the data confidence fabric billing manifest immutable by signing the data confidence fabric billing manifest;
creating a snapshot of the data confidence fabric billing manifest, wherein the snapshot comprises parameters including a smart contract billing logic, a data owner identification, digital wallet information of the data owner, vendor information of a trust service, a time to activate the smart contract billing logic, and a digital signature signed in the data confidence fabric billing manifest;
storing the snapshot of the data confidence fabric billing manifest at an initial node of a plurality of nodes;
broadcasting the snapshot to a specific subset of the plurality of nodes of the data confidence fabric, where the specific subset does not include at least one node of the plurality of nodes;
commanding a data confidence agent to pull the snapshot from the initial node where the snapshot is stored;
in response to the commanding, pulling, by the data confidence fabric configuration agent, the snapshot from the initial node;
deploying, by the data confidence fabric configuration agent and at the specific subset of nodes, the smart contract billing logic included in the snapshot of the data confidence fabric billing manifest; and
activating, by the data confidence fabric configuration agent, the smart contract billing logic at the time and at the specific subset of nodes, thereby provisioning the trust services at the specific subset of nodes, where the activating further includes tracking and billing for the trust services rendered at the subset of nodes according to the parameters of the snapshot.
