An Approach for Smart Gateways to Collect Data and Automate It on Block-Chain

Blockchain is a technology that has received a lot of attention in recent years, employing a distributed consensus mechanism that ensures the credibility and integrity of data through the verification and approval of multiple parties [1] [2]. Due to its decentralization, immutability, security, reliability, and traceability, blockchain is widely used in various fields such as finance, logistics, and healthcare. Currently, common methods of uploading to the blockchain include interfacing business systems to the blockchain, data lake to blockchain, and manual uploading, among others [3]. These methods have brought significant inconvenience to the uniform management of data uploading across systems. Moreover, these methods do not involve directly collecting source data from endpoint devices to the blockchain, leading to a “vacuum” period for data credibility control between the time data is collected and uploaded to the blockchain. During this period, there is a risk of data tampering, and the security, integrity, and authenticity of the data cannot be effectively guaranteed. Therefore, this paper proposes a solution for automatically collecting and uploading carbon emission data from thermal power plants directly to the blockchain, aimed at ensuring the “last mile” before data is uploaded to the blockchain is secure, trustworthy, and immutable.
