The used car with the mileage certified by blockchain

“Would you buy a used car from this man?” They asked for US election posters in the 1960 presidential elections, trying to discredit Nixon with a sly-looking photo of him and a question that reached the core of American concerns. The used car market is the one that has increasingly lent itself to fraud and a lack of transparency. The car salesman is an iconically fraudulent figure who profits on the ingenuity of buyers by masking the history and defects of the cars. Looking for a safe and space-free way for counterfeiting to certify used cars, blockchain comes to the rescue. A recent Chinese study published in The Journal of Supercomputing highlights how in the used car market, which in China is worth over 1 billion dollars and is constantly growing, there is a strong asymmetry of information between those who sell and those who buy, given the lack of a centralized system that allows the history of the vehicle to be traced. This asymmetry makes it easy for the seller to hide the real condition of the vehicle, and deteriorates the reliability of the entire market. The study proposes the use of smart contracts based on the Ethereum blockchain to guarantee the truthfulness of information in a direct and transparent way, without the costly intervention in economic terms and time of experts and third parties as a guarantee. Mercedes-Benz sales team has teamed up with PlatON to create a blockchain platform that aims to store data from the entire vehicle life cycle, including the insurance report, transfer of ownership, possible involvement in accidents in order to calculate the residual value of the vehicle from the moment it leaves the factory using an algorithm. In the United States, Carnomaly, the crypto platform dedicated to the automotive world, announced in June its blockchain project that certifies used vehicles allowing for safer and more transparent trading. In Italy there is no certification on the car, but with Autocerta it is possible to have it on the ads. The Turin-based startup, which has just successfully concluded its crowdfunding campaign with results exceeding expectations, has devised a software capable of verifying the information within the internet ads relating to used vehicles. tried to buy a car by looking for it on the internet, they are a world where it is very easy to waste time and risk scams due to fake ads. The system designed by Autocerta, completely automated, starts from the recognition of the license plate present in the announcement, passes to the download of the vehicle data from institutional and dedicated databases and arrives at the comparison of the actual ownership of the vehicle by intertwining the data of this with the number of frame. In the event that the vehicle has already been subjected to revisions, the declared kilometers and historical revisions are checked with cross-checks. This procedure eliminates the possibility of “errors” in the loading of standard equipment and automatically certifies the announcements by generating a unique code for each advertisement that the buyer can use to view the vehicle file and download the Car Dossier. A blockchain certified pdf file that contains all the information on both the vehicle and the dealer, to give the customer a complete picture. Autocerta certainly does not compete with ad portals, but is complementary to them. Allowing the correct sellers to assert their reliability thanks to the certification process of their ads carried out by a third party super partes, and provides the tools, through its app, to insert photos and vehicle data directly on the platform, so that the uploaded ad is immediately certified.
