Title: SYSTEMS AND METHODS FOR FAIR INFORMATION EXCHANGE USING PUBLISH-SUBSCRIBE WITH BLOCKCHAIN
Abstract:
Methods, apparatus, systems and articles of manufacture are disclosed to facilitate information exchange using publish-subscribe with blockchain. An example apparatus includes a broker including a processor and a distributed ledger module. The example distributed ledger module stores a message to be relayed by the broker from a publisher to a subscriber. The example processor is to at least compute, triggered by receipt of the message by the broker, a proof-of-work (PoW) function. The example processor is to at least verify the computation of the PoW function. The example processor is to at least transmit, upon verifying the computation of the PoW function, the message to the subscriber. The example processor is to at least process feedback received by the broker to update the PoW function.
