Abstract: Systems and methods for using a distributed ledger to maintain a blockchain are provided. An example method includes receiving transaction information associated with a transaction involving a service provider and a consumer, the transaction information including transaction terms and conditions, receiving an indication, the indication indicating that the consumer assented to the terms and conditions, creating a transaction record, the transaction record including a transaction identifier, a consumer identifier of the consumer, the transaction terms and conditions, and the indication, creating a block in a blockchain managed by a blockchain as a service (BaaS) system, and storing the transaction record in the block.

Abstract: Fault-tolerant multicast networks via network coding comprises a digital signal operator that combines data signals multicast from multiple sources and transmits the combined data signal via a link to the next or destination node. In one aspect, the digital signal operator includes an exclusive-OR operator that performs a Boolean exclusive-OR function on the received bit streams of the multicast data from the plurality of sources.

Abstract: The method, system and user-interface facilitates patient compliance with healthcare provider instructions for prescription medication after discharge from a healthcare facility by analyzing patient current medication, canceling open prescriptions no longer used by the patient, aligning verified patient current prescriptions with patient discharge prescriptions, thus limiting the number of occasions on which a customer must visit the pharmacy to retrieve refills of the aligned prescriptions, and providing follow-up education at multiple occasions after discharge, decreasing the likelihood that the patient will be re-admitted to the hospital for the same ailment or complications from that ailment and increasing the likelihood that the customer will comply with the recommended medication regimen.
