An Architecture for Electronic Exchange of Official Document Based on Email and Blockchain

Abstract

Official documents are considered as a critical communications channel among agencies, organizations, and the public. With the rise of e-government, most official documents have been evolved from printed to electronic form in recent decades. However, the convenience of electronic documents also brings higher security risks. Through the integration of email and blockchain technology, this study proposes an architecture for the electronic exchange of official documents to bridge the gap between convenience and security. With the verification of the proposed system, the findings provide a valuable reference for the governance of agencies.
