The technology also makes it possible to issue temporary access authorizations to the vehicle. Through the blockchain mechanism, a protected connection to vehicle data and functionalities is established. At the same time, it secures all communication between all participants. Third parties can be integrated without additional hardware via so-called "Smart Contracts". Smart Contracts are automated contracts that trigger transactions when pre-defined conditions are met. This means that compliance with the contract is technically guaranteed. With this technology, Porsche also intends to support the electrification of its fleet. "Starting with faster, more secure authentication at the charging station through to the payment process," says Uwe Michael, Head of Electrics/Electronics Development at Porsche.
The sports car manufacturer is also working on new business models based on the block chain: Data to be processed is encrypted locally in a distributed block chain using auditable data logging. All activities are documented in the blockchain, making erasing processes transparent. On this basis, autonomous driving can be offered with improved functions in the future: Through local data, regional learning effects can be achieved and securely shared with other vehicles. The customer can access swarm data in a privacy-protected process.
In the summer of last year, start-up XAIN won the first "Porsche Innovation Contest" on the subject of blockchaining and prevailed against more than 100 other applicants. Subsequently, Porsche's cross-departmental teams developed and tested applications together with XAIN within three months. The blockchain was integrated into the Porsche Panamera by XAIN using an energy-efficient mining process. In addition, Porsche is currently working on further applications of the technology, for example in the area of loading and parking.
XAIN offers various solutions in the area of block chain and artificial intelligence, with focus on intelligent industrial applications. The founders Leif-Nissen Lundbæk and Felix Hahmann are particularly active in the automotive industry, where they started their careers. In recent years, XAIN, together with researchers from the University of Oxford and Imperial College London, has developed a blockchain system that significantly reduces energy consumption in mining. The XAIN solution can also be used for mobile devices and vehicles.
