An Engineering Data Trusted Sharing Service Platform Based on Blockchain

With the digital transformation of enterprises, the requirements for the integration of systems in the construction industry are getting higher and higher. Data standardization, system decoupling and data docking, and data lake warehouse construction have become one of the key research directions. Traditional data storage and sharing methods are often vulnerable to various threats and attacks, and there are risks of tampering, deletion, forgery, and leakage. This paper builds an engineering data trusted sharing service platform based on blockchain technology, which improves the blockchain using the SM2 elliptic curve public key cryptography algorithm and SM3 cryptographic hash algorithm. This platform can be applied to various types of engineering enterprises to achieve convenient and secure sharing of engineering data.
