The rapid development of the Internet of Things, combined with the spread of solutions and cloud applications (i.e. a virtual cloud of computer arrays that provide computing resources over the Internet) and the continuous evolution of technologies and network infrastructures, besides the advantages offered, simultaneously creates concerns about the reliability of the devices involved in the network and secure data transfer between them. This thesis aims at the development and presentation of a new model for certification of qualitative data handling within a network of interconnected devices and the development of trust among members of a network cloud. This could be achieved by using as a basic idea the technology of the most successful digital currency, the Bitcoin. Inside the trading network that uses the Bitcoin, transparency and security of transactions are ensured by the use of a distributed database where all valid transactions are recorded. This requires users who check and certify these transactions, and these users are called miners. In order to implement this thesis, a program was developed. This particular program simulates data transactions between devices on a network and uses the basic features of the Bitcoin (with the necessary changes) for the certification of sending and receiving qualitative data.
