A multi-transaction mode consortium blockchain

Abstract

It is difficult to apply the bitcoin transaction system's blockchain technology outside the electronic currency transaction. This paper proposes a Multi-Transaction Mode Consortium Blockchain (MTMCB), which generalizes the traditional buying and selling transaction into event processing of the business system. It prevents all kinds of high value event processing results from repudiation and tampering. MTMCB is low-cost and obtains credible results without accumulating technology. It extends the user type (not only the PC user), the storage type (not only local storage) and the storage content (not only the block data). MTMCB optimizes transaction verification, consensus decision, block generation, block storage, comparative verification and block linking mechanism. It provides visual audit services, including event proof, abnormal transaction early warning, tampering discovery and reconstruction, etc. Meanwhile, example simulation, security analysis and performance analysis are processed. Its results show that MTMCB has the same security level as the bitcoin core transaction system, and it has good adaptability in data resource protection of high value event processing.
