This week the German automaker Volkswagen in its Twitter announced cooperation with the blockchain project IOTA, which develops solutions in the field of the Internet of things. At the CEBIT 2018, the companies are planning to show a new experimental sample of their joint project on the use of the IOTA DAG network.
This project is designed to solve the key problem of secure transmission of transparent, undamaged software updates “by air” (OTA) to the network of autonomous vehicles. Now the data is distributed centrally, so there is no guarantee that the information delivered to each car is genuine and unchanged. This problem can be solved using a distributed registry or other similar technology.
In addition, because the scope of autonomous vehicles continues to grow, the system must not only decentralize to monitor each update, but also be able to scale to the right size to cope with the increasing load on the network. Another major factor is security. This factor will become more important when cars become more dependent on software for performing basic tasks and functions related to security.
Johann Jungwirth, Volkswagen’s senior director of digital engineering and member of the IOTA Foundation’s Supervisory Board, believes that the technology of a decentralized distributed registry will form the basis of a safe ecosystem that does not require participants to trust each other – just the one Volkswagen needs to further develop its the project of autonomous cars. He calls IOTA “an excellent example of how distributed registry technology can be used in the future.”
