Porsche is the first automaker to test blockchain applications in vehicles, thanks to a collaboration with Berlin-based startup XAIN. Testing has included locking/unlocking the vehicle via an app, temporary access authorizations, and new business models based on encrypted data logging.

While blockchain is new to transportation, the decentralized protocol for data transactions between business partners forms the basis of cryptocurrencies such as Bitcoin and Ethereum. Every change is recorded in chronologically arranged data blocks, making it transparent and tamper-proof.
