We digitalize the history of the motorcycles, we use Blockchain to guarantee his immutability in time, with use IOT to give voice to motorcycles We solve the problem of asymmetry of the information that generates three main problems in the second-hand motorcycle market: lack of trust between buyer and seller, low average motorcycle price, low or null value of motorcycles accessories and modifications. Motoblockchain collects the documentation about the history of the motorcycles and it uses Blockchain to make it tamper proof, while giving to the user full control over it in a full GDPR compliant system. Owners can save all the information related with motorcycle’s life in our platform that is constantly connected with the Blockchain: owner’s history, mileage in time, invoices and money invested in modifications, accessories, improvements, revisions, as well as all the photos of the related components. We access motorcycle data with the MOBD (patented) IOT system equipped with OBD II connection and IOT sensors: it makes the motorcycle autonomously update data into the Digital Identity. The MOBD additionally provides several disruptive functionalities designed to improve user's safety and collected in one unified IOT tool: predictive failure detection, remote failure detection, incident detection and emergency call (eCall) services). We use Big Data & AI to analyze the data recorded and to serve it to insurance companies and motorcycle manufacturers (OEM). Every user can decide the level of privacy of each document, he can decide with whom to share it and finally he can use it to create trust with the buyer so generating added value during the sales process. The Digital Identity created is inherited by the new owner after that the motorcycle sales ends. The Motorcycle Digital Identity system creates trust and provides symmetry of the information between users, consequently it solves all problems mentioned above.
