Abstract: A method for conversion of digital assets to fiat currency using a secondary blockchain and mirrored accounting includes: receiving transaction data corresponding to a first blockchain transaction processed using a first blockchain, the transaction data including a payer identifier, recipient identifier, and blockchain currency amount; validating an entity as an authorized entity associated with the payer identifier; determining a fiat currency amount based on the blockchain currency amount; generating a second blockchain transaction, the second blockchain transaction including an unspent transaction output, destination address associated with the authorized entity, and the blockchain currency amount and/or the fiat currency amount; confirming addition of the second blockchain transaction to a second blockchain; and initiating a transfer for the fiat currency amount from a first transaction account to a second transaction account, the second transaction account being associated with the authorized entity.

Abstract: A method for physically displaying and manipulating a communication network through physical objects and an interactive display includes: positioning, on a surface of an interactive display screen, a plurality of physical objects, each representing a node in a communication network; displaying a topography of the communication network including at least a plurality of nodes, where each node represented by a physical object is displayed beneath the respective physical object, and where open communication channels between nodes are visually displayed on the screen; receiving a physical gesture performed by a user between two of the plurality of physical objects; transmitting a signal to one of the physical objects or an access point of the communication network causing manipulation of the communication network based on the physical gesture; and updating the displayed topography of the communication network based on the manipulation of the communication network in real-time.

Abstract: A method for private management of digital assets for multiple participants of a global blockchain includes: receiving, by a receiver of a processing server, a transaction notification for a proposed currency transfer, the transaction notification including at least a sending identifier, a recipient identifier, and a transfer amount; generating, by a processor of the processing server, a transaction data value for the proposed currency transfer, the transaction data value including at least the sending identifier, the recipient identifier, and the transfer amount; applying, by the processor of the processing server, a cryptographic hashing function to the generated transaction data value to generate a hash value; publishing, by the processor of the processing server, the generated transaction data value to a private blockchain; and publishing, by the processor of the processing server, the generated hash value to a public or permissioned blockchain.

Abstract: A method for facilitating secure private transfers in a blockchain includes: receiving an initiate message from a device for a proposed private transfer including a private group identifier, entity identifier, and transfer amount; executing a smart contract using the initiate message as input resulting in transmitting an event message to a central authority system including the entity identifier and transfer amount; receiving a response message from the central authority system including an indication of approval or rejection of the proposed private transfer; and executing the smart contract using the response message as input resulting in (i) adding a private blockchain transaction for transfer of the transfer amount from a first blockchain wallet associated with the entity identifier to a second blockchain wallet in a private group associated with the private group identifier if the response message includes an indication of approval, or (ii) declining the proposed private transfer.
