现有科技服务业数据管理中普遍存在着数据标准多样化、数据壁垒多的问题,导致数据交互的及时性与安全性难以得到保障。区块链即服务(BaaS)同时具备区块链技术的去中心化、不可篡改、分布式存储等特点,以及云计算带来的高扩展性和巨大算力,正在催生科技服务业新商业模式的出现。应用BaaS、智能合约和混合加密技术,构建科技服务业数据共享的系统结构；基于系统结构和数据分类结构,构建科技服务业数据共享的实现机制。为科技服务业数据管理提供了融入BaaS的架构和思想方法,在去中心化、安全可靠的环境下实现科技服务业数据的高效整合与共享,以满足科技服务业日益增长的数据需求。

In the existing data management of the science and technology service industry, there are generally problems of diversified data standards and data barriers, which makes it difficult to guarantee the timeliness and security of data interaction. Blockchain as a service has the characteristics of decentralization, immutability and distributed storage of block chain technology, as well as the high scalability and huge computing power brought by cloud computing, which are spawning new business models in the science and technology service industry. Using BaaS, smart contracts and hybrid encryption technology to build a sharing system structure of the science and technology services. Based on the system structure and data classification structure, constructing the realization mechanism of data sharing in the science and technology service industry. Providing the BaaS architecture and thinking methods for the data management of the science and technology service industry, and realizes the efficient integration and sharing of data in the science and technology service industry in a decentralized, safe and reliable environment to meet the growing data needs of the science and technology service industry.
