Abstract
A method of data transfer over a communication network from a first information handling apparatus to a plurality of second information handling apparatuses includes generating, by the first information handling apparatus, an initial block and initializing, based on the initial block, a ledger. The method includes broadcasting the ledger to the plurality of second information handling apparatuses, and attempting to compute a new block, by each one of the plurality of second information handling apparatuses. Upon one of the plurality of second information handling apparatuses successfully computing said new block, the method then transmits data to the one of the plurality of second information handling apparatuses and updates the ledger based on the new block.
