Soil pollution control has become one of the environmental issues that governments in various regions are gradually paying attention to. However, under the Internet of Things (IoT) environment, the storage and traceability of soil environment data has become an important challenge for the future. In addition, the credibility of soil pollution data is also an important prerequisite for soil remediation. Third-party or on-machine regulatory units need real and credible soil data to support environmental governance and accountability. To tackle the problem of soil data tampering in IoT scenarios, this paper presents a blockchain-based data storage framework. The study is based on Ethereum smart contracts and Orbit-db soil data to achieve soil pollution data tamper-proofing. At the same time, we also solve the problem of on-chain of large amounts of real-time data or log data generated by IoT devices through the improved Merkle mountain (KMMR)computation data digest. Our experimental results show that KMMR not only improves the efficiency of data chain calculation but also reduces storage costs.
