Abstract:At present, the sampling and testing platforms in China have low degrees of information and intelligence, leading to low sampling and testing efficiency. Moreover, the centralization of such platforms has contributed to data tampering and untrustworthy data sources. In response to these problems, a solution based on Blockchain technology is proposed for sampling and testing. By leveraging the multi-center, tamper-resistant, and privacy-protecting characteristics of the alliance chain in Blockchain and using Internet of Things (IoT) terminal equipment to monitor the process in a smart fashion, this study proposes a sampling and testing platform featuring safe and credible data and a monitorable process, which improves the efficiency of sampling and testing and the credibility of test results and also ensures the security of data.
