Designing confidentiality-preserving Blockchain-based transaction processing systems

Blockchain is one of the most disruptive and promising emerging technologies, and it appears to have the potential for significantly affecting the accounting and auditing fields. Using blockchain technology, zero-knowledge proof, and homomorphic encryption, this paper presents a design for a blockchain-based transaction processing system (TPS) and develops a prototype to demonstrate the functionality of the blockchain-based TPS in real-time accounting, continuous monitoring and fraud prevention. The computational performance of a blockchain-based TPS versus relational databases is evaluated and discussed. In anticipation of the wider applicability of blockchain technology to support enterprise information systems and continuous monitoring systems, this paper presents an innovative design that utilizes the advantages of blockchain technology while overcoming some of the key barriers to its adoption.
