A computer-implemented method for managing enterprise transactions includes creating an overlay to a physical communications network, adding one or more nodes to the overlay, designating one or more nodes of the overlay as super nodes, generating a distributed ledger to store the transactions, and replicating the distributed ledger to all nodes of the overlay. Generating the distributed ledger includes receiving, at the super nodes, transactions from the one or more nodes, assigning, by the super nodes, the transactions to a variable size block, validating, by the super nodes, the variable size block, and linking the validated variable size block to the distributed ledger.
