The CSP node configures a first group of blockchain nodes according to the first network configuration and the first credentials. Further embodiments include transmitting the first credentials to a public server that sends it to a public blockchain node and an indication to generate a portion of the federated blockchain network. The public blockchain node configures a second group of blockchain nodes according to a second network configuration based on a public blockchain smart contract. The federated blockchain network comprises the first group of blockchain nodes and the second group of blockchain nodes. Other embodiments are disclosed. ## Claims ### Claim 1 A device, comprising: a processing system including a processor; and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising: transmitting first instructions and a first network configuration to a cloud service provider (CSP) node, wherein the first instructions indicate to the CSP node to configure a first group of blockchain nodes according to the first network configuration, wherein the CSP node configures the first group of blockchain nodes utilizing first credentials;
