Blockchain-based upgrade design of the Grand Canal digital document system

Abstract

The purpose of this paper is to discuss the design and implementation of the upgrade of encryption technology of the Grand Canal digital document system based on blockchain technology. Based on the core technologies of blockchain's distributed ledger, smart contract and encryption algorithm, this study proposes a novel upgrade scheme for the Grand Canal digital document system. The scheme realizes the non-tampering and full traceability of document data by constructing a decentralized document storage architecture, and optimizes the document management process by using smart contract technology and asymmetric encryption algorithm to ensure the security of document transmission and storage. As a modern technology with strong confidentiality and security, blockchain is extremely important for data protection, and is of great practical significance for promoting the digital inheritance and innovative development of the cultural heritage of the Grand Canal.
