What is blockchain?
Blockchain is basically a chain of digital data blocks. Each block contains large numbers of transactions – i.e. digital information, for instance on accounts, products, events, and much more besides. The individual transactions are stored as blocks, with each block including a reference to the previous blocks. The data blocks are in turn linked to create a chain – hence the term blockchain.
The key feature of this electronic register is its distributed data storage. It is stored on a host of networked computers and managed by the participants. The same data chain with the same information is stored on every computer and is constantly synchronised.
So everyone involved shares the same version of the data, which works according to jointly defined rules. There is always only one truth – this feature makes the blockchain uniquely transparent and secure. Remote storage means that the data chain can only be modified if everyone involved agrees. Making tampering virtually impossible.

What we do
At DB Systel, Deutsche Bahn's digital partner, the Blockchain team has been developing promising ways of deploying blockchain technology at Deutsche Bahn since 2018. The ideas range from multimodal ticketing, logistics supply chains through to technical rail operations using blockchain. At present around 30 developers, software architects and project managers are working on some 20 use cases. The work covers research, development of prototypes, right through to practical usage.
