Application of Blockchain Technology in Accounting Information Transparency: Theoretical Framework and Algorithm Implementation

In view of the problems of human error and data tampering in traditional accounting information systems, this paper uses blockchain to ensure that accounting information is stored and replicated on multiple nodes, and ensures that all nodes in the network verify transactions through a consensus mechanism; in addition, the application of smart contracts automatically executes contract terms and reduces human intervention. Blockchain technology improves data sharing rate (up to 96.9%), data encryption coverage (average 95.6%) and accounting information quality (data error rate is reduced). This paper provides new theoretical support and technical solutions for optimizing accounting information disclosure.
