Abstract
The present disclosure provides a distributed computer system, which includes a plurality of computing devices. Each computing device includes a memory, a portion of a Blockchain, a transceiver, and a processor. The memory stores a plurality of data transaction requests. Each data transaction request corresponds to a block in the Blockchain and includes a cryptographic hash of a previous block, a timestamp, and transaction data. The transceiver receives a data transaction request from a subset of the plurality of computing devices. The processor determines whether the received data transaction request corresponds to at least one block in the portion of the Blockchain. The processor updates an internal record of the Blockchain, based on determining that the data transaction request corresponds to at least one block in the portion of the Blockchain. The processor then verifies the updated internal record of the Blockchain with a computing device in the subset.
