The security of circulating and processed data on digital platforms reveals new security needs. In this study, a model is proposed that the transaction records of the devices and the data obtained from the sensors on a designed internet of thing network they cannot be tampered with blockhain technology. In proposed model, by making the necessary settings of the operating system installed on the Raspberry Pi 3 and writing additional services to the operating system, the Raspberry Pi 3 has been turned into access point devices. In this way, internet of thing network was established by offering internet access service to clients who will be members of internet of thing network. Records of the transactions that take place on the internet of thing network are stored in the Raspberry Pi 3 by converting them into a blockchain structure. In addition, the raw data was sent to a server with hyperledger fabric installed on it. A blockchain software using hyperledger fabric framework running on the server was realized. This software is configured to convert motion records of devices that are members of the internet of thing network to be sent to it into a blockchain structure. Thanks to the hyperledger fabric framework, which has a distributed structure, the loss of data and the risk of modification given by the ledger structure are eliminated. The security and storage of data about the operations of all internet of thing devices operating on internet of thing network established with this created system are maximized.
