Abstract
A commodity-measuring device for autonomously selecting a commodity supplier among a plurality of commodity suppliers being specified within a blockchain distributed database is provided. A microcontroller unit is configured to provide commodity consumption data to the transaction manager. A storage is configured to store a private key, and a communication module is configured to retrieve a commodity supplier file stored in the blockchain distributed database, and the commodity supplier file includes parameters of a commodity supplier and a program. A transaction manager is configured to determine autonomously, based on the commodity consumption data and parameters in the commodity supplier file, whether to select the commodity supplier; and if the determination is positive, the transaction manager is configured to, using the private key, send a transaction to the blockchain distributed database calling a function in the program to associate the commodity supplier file with the identifier.
