Abstract

The disclosed exemplary embodiments include computer-implemented systems, devices, and processes that securely manage transfers of digital assets between computing devices using permissioned distributed ledgers. By way of example, an apparatus may receive, from a first device, a request to transfer a digital asset to a second device and a first digital signature applied to the request. Based on a validation of the first digital signature, the apparatus may approve the request and apply a second digital signature to the request and the first digital signature indicative of the approval of the request by the apparatus. The apparatus may also transmit the request, the first digital signature, and the second digital signature to a computing system, which may validate the first and second digital signatures and perform operations that record the first public key and asset data identifying the digital asset within at least one element of a distributed ledger.
