Porsche is the first to implement blockchain in the car

February 26, 2018 // By Christoph Hammerschmidt
Together with Berlin-based start-up XAIN, sports car maker Porsche is currently testing blockchain applications in the vehicle. The applications tested range from locking and unlocking the vehicle via app, to time-limited access authorizations and new business models through encrypted data logging. The technology can also be further developed to improve autonomous driving functions, says Porsche.

The block chain is a distributed protocol for data transactions between business partners - also the known cryptographic currencies Bitcoin and Ethereum work in this way. Every change there is recorded transparently and forgery-proof in chronologically consecutive data blocks. According to Oliver Döring, financial strategist at Porsche, this holds enormous potential: "We can use it to transfer data faster and more securely and thus offer our customers even more convenience in the future, be it for loading, parking or to guarantee temporary access to the vehicle for third parties, such as a parcel delivery service".

The developed services based on the blockchain are fast and are considered to be very secure. The car becomes part of the blockchain so that a direct connection is possible without detours via a central server. The process of opening and closing the car via app is thus up to six times faster with a duration of 1.6 seconds than with previous solutions, whose request is first forwarded to a server in the backend and then approved from there. The connection is throughout cryptographically encrypted. The log process ensures that all activities are unchangeably documented in the block chain and can be viewed via app. In this way, access authorizations can also be securely distributed digitally and tracked by the vehicle owner at any time. The access rights can also be granted remotely.
