The Blockchain represents the evolution of civil society concerning the exchange of values. But it goes even further. Where we have transmission of value (virtual currency trading between accredited subjects through blockchain), we will have an exchange of information, data relating to the subjects of the transaction, economic values of identifiers -such as date and time of the transaction- and a series of other technical information that allows security and process certification. This consideration is fundamental for a new and more extensive use of Blockchain, which increases its usefulness to all data transmission contexts, especially in scenarios where it is important that these data are tested and certified as well as the actors involved in the flow . The main example of this use today is represented by the emerging IoT (Internet of Things) scenario, that is conquering the world of localized  surveys through sensors connected to the Internet -. sources of information that can be received anywhere in the world. Sensors, actuators and in general any source or data receiver, placed on the territory, allows to keep under control extensive areas for different purposes, from the world of agriculture to climate control, from the automation of routine maintenance processes in industries, offices or infrastructures such as roads or entire residential, tourist or public utility complexes. The IoT is now everywhere and carries a huge amount of information, finally made available through cloud services or global databases, with great advantages in the development of big data management systems. The next step must necessarily be the certification of such data and how to manage (handle?) their security. It must be considered that any data retrieved from a sensor is today put together with millions of other information in a big data system that generates results, which meet various needs. This data represents a value (also in economic terms) which is at the basis of the sustainability of the IoT process that generates it. This value can be greatly amplified, enriching the process of characteristics such as:certification of sources: the blockchain is able to guarantee that a specific data has been issued by a specific sensor;certification of information: the blockchain can guarantee that a specific piece of data was produced exactly on that day and at that time;security against sensor tampering: if inserted as “peers” (or nodes) in the chain of blocks, the sensors transmit and receive only from other “peers” of the chain, which are themselves certified. This prevents external access to sensors and mostly avoids the use of sensors connected to the Internet for purposes that do not conform to their nature (such as DoS attacks to third-party systems through the enormous volume that can be generated by entire IoT networks under control of malicious people). We need to solve the most pressing requirements  in the world of IoT installations, which are exponentially growing; it’s typical needs of enterprise processes.A technology designed and built to solve the problem of transmitting a Bitcoin from A to B without the presence of a central control and validation body, is developing as a new paradigm in the management of data transmission.Imagine how useful it is to transmit secure and certified information without having to transit through central bodies, such as notaries or secretariats. Or how much faster and safer it would be to buy without the need for guarantee intermediation, or to manage property rights,  assets properties or “works of genius” without having to centralize them in databases by third parties. All this considering that at any time in the future, even within hundreds of years, such certified information will still be available, unchanged as originally recorded in the chain of blocks.
