Shop Window Secure Digital Identities

With its innovation competition “Showcase Secure Digital Identities”, the Federal Ministry of Economics and Energy (BMWi) has called for the development of convincing concept ideas for the broad application of Secure Digital Identities (SDI). The competition is to focus on municipalities, cities and metropolitan regions. Under the name STEREO, a consortium from the Hamburg metropolitan region has successfully applied and is working out its concept idea in competition with ten other consortia from other regions in Germany between June and November 2020. During this period, the feasibility and practicability of the concept has to be checked, obstacles identified and the prerequisites created for a quick and efficient implementation of the concept idea in a subsequent implementation phase. At the end of 2020 it will be decided which consortia may test their concepts in a three-year implementation phase starting in April 2021.

STEREO – the project from Hamburg

The approach of the STEREO consortium: We create the secure digital identity for municipal mobility services. In doing so, it is important to us that citizens can register and log on to services on the Internet using simple, fast and trustworthy procedures. The protection of personal data has the highest priority. Our project focuses on the high relevance of the STEREO Use Cases in everyday life. To ensure this, we are approaching citizens and ask for their support.

Identities form the basis for trust by reflecting the certainty of knowing a partner in action. To avoid misuse, however, not only the identity of the owner, but also the identity of the object triggering the action must be electronically verifiable without any doubt. This is where the STEREO project comes in by generating and linking secure digital identities of vehicles, their owners and users. Vehicle owners can identify themselves completely digitally via their smartphone or tablet and use an ID solution of their choice. The digital identity thus created, in combination with the vehicle’s digital right of disposal, serves as the basis for a variety of usage scenarios in the mobility world of the future
The STEREO use cases

The use cases were selected with a view to daily vehicle use in order to ensure the greatest possible coverage and transferability to everyday situations. It is possible that further use cases will be added. It should also be noted that the use cases are not yet final in terms of design.

For almost three years it was on the agenda at CHAINSTEP: in the Digital Hub Logistics Hamburg regular events belong to “Business Blockchain” with a focus on logistics and supply chain management. For COBILITY and with our partners and customers, we have already held various events at the hub, but it was IBM that gave us the impetus for our first Hub meetup (in this case together with IBM) on our core topic – Business Blockchain.

Title of the event: “Blockchain in real life.” A good fifty participants ensured a well-filled Meetup Room. After the welcome by Johannes Berg, Managing Director of Digital Hub Logistics Hamburg, Christan Schultze-Wolters, IBM Business Unit Manager Blockchain Solutions D-A-CH, gave an interesting overview of the various activities within the IBM Food Trust Initiative. The charts are available here.

Afterwards, three members of the HANSEBLOC consortium (Sovereign Speed, Kühne Logistik Universität (KLU) and CHAINSTEP) explained the state of development of the BMBF-funded project. Click here for the presentation and here for the project page.

After the presentations there were several questions from the interested audience. A nice get-together with finger food and drinks rounded off what we believe was a successful event.

For CHAINSTEP this was the starting signal for further Meetups around Business Blockchain. We are planning events on the blockchain-based ecosystems that are currently being created for the maritime industry, on our previous customer projects and on other current funded projects. At the request of many of the participants of the Meetup on 25 February, we will also be holding a basic event “Getting Started with Business Blockchain”, where participants will have the opportunity to discuss their questions about the use of the blockchain with experts after an introduction to the topic.

On Oct 22 Blockchain was the main topic at the Bremen Cotton Exchange. Leonard Pust (BitMoin) and Jan Christoph Ebersbach, Head of Blockchain Engineering (CHAINSTEP), organized a training and workshop day together for the first time. The participants were as enthusiastic as we were. The combination of training and workshop in one day efficiently combined theory and practice and concrete next steps could be defined.

At 8.30 a.m. we took a courageous step into the paternoster in the historic building of the Cotton Exchange, directly on Bremen’s market square. The journey to the 5th floor was a problem-free one, but we had to get in and out of the car. The stop was a good foretaste of our event. Right at the top of the cotton exchange, in the impressive tower hall, we trained the basics and applications of blockchain technology from 9 am to 12.30 pm. From 1 p.m. the number of participants was reduced and the use of Blockchain in the promotional project “Room for Innovation, Blockchain for GMO sizing of organic cotton” was worked on. Lots of material for little time.

What was particularly remarkable for me was that the Cotton Exchange opened up the circle of participants for training and invited companies and organisations that did not participate in the project. In this way, the Blockchain Fundamentals could be made accessible to a wider audience and ideas and questions could be raised beyond the scope of the project.

In the second part of the day, after the lunch break, we applied the Blockchain theory to the project in a small group with the partners of the project. Both our technical architectural knowledge of the corporate use of blockchain and our experience in developing business models with blockchain were in demand. The next step is to put the ideas on paper and obtain feedback.

For the 2nd COBILITY Workshop 30 participants met this time to talk about two concrete Use Cases: “smart load carriers” and “dangerous goods transport” can be used. The diversity of the participating companies was particularly exciting in the group work.

The next steps already have been decided. On the one hand, the topic “dangerous goods transport” will be discussed with the working group of the DSLV, on the other hand, the participants in the load carrier workshop have worked out that it makes sense to find out the cooperation potentials with the GS1 pallet project from the year 2018.

After this important milestone, we are now starting the further development of the COBILIT organisation.


A high-ranking visitor to the Digital Hub Logistics: on 7 December 2018, Michael Westhagemann, the Senator for Economic Affairs in office just a few weeks ago, visited the innovation factory for logistics in Hamburg’s Speicherstadt warehouse district. Johannes Berg, Managing Director of the Hub, surprised our guest with a gift: “Senator Westhagemann will receive an “honorary job” at the Digital Hub Logistics for 2019. The gift was well received, as this tweet shows:

On behalf of all the “Hubbers”, I think I can say that we enjoyed the humorous speech by Senator Westhagemann that followed. His interest in and obvious pleasure in technology, as evidenced by his many years of top management experience in the IT environment, is certainly an excellent basis for Hamburg’s further development of innovative, technology-supported topics.

Senator Westhagemann then took an impressive amount of time to present various start-up concepts. CHAINSTEP had the opportunity to jointly present to the Kroschke Group (a leading service provider in the field of vehicle registration) the jointly developed prototype “carTRUST” for blockchain-based secure online registration of motor vehicles. Senator Westhagemann was very interested in the idea of piloting the concept for the first time in Hamburg – also with a view to the ITS World Congress 2021. Next steps have already been discussed, we are very curious whether we can manage it :-).

At the Digital Summit in 2018, the Federal Ministry of Economics and Technology clearly focused on artificial intelligence. Since the Bitkom did not want to ignore blockchain technology, the association organized a blockchain business summit on the first day of the digital summit at the same location as the summit, i.e. in the Nuremberg exhibition halls. The popularity of the event, which the organizer was right to hold with the Blockchain event, was confirmed: well over 300 participants informed themselves about the possibilities that Blockchain technology already offers today in the corporate environment.

Dr. Nussbaum, State Secretary in the BMWi, and Dr. Rohleder, Managing Director of Bitkom, opened the event. Afterwards there were some top-class lectures from different IT and telecommunications service providers as well as from the scientific side. The lecture by Professor Dr. Volker Skwarek, who is also a member of CHAINSTEP’s advisory board, on the topic of Smart Contracts Industry 4.0 Applications was well received.

Together with Thomas Müller, CEO of, we had the opportunity to present the initiative COBILITY. The presentation is linked here. The following discussions at the “Meet the speakers” booth showed how high the interest of professional IT and telecommunication service providers is to understand and use the possibilities of decentralized governance.

Below you finde some impressions of the event as well as the link to the video of the COBILITY part.

Three months after the announcement of the COBILITY initiative, the time had come on 28 November 2018: 22 participants from 16 companies and institutions met for the COBILITY kickoff at the Digital Hub Logistics in Hamburg’s Speicherstadt.

After a brief introduction of the participants and the objectives of the COBILITY initiative, the detailed work began with the aim of defining the first applications based on the COBILITY concept. COBILITY focuses on three aspects in particular:

  • decentralised governance
  • based on open standards
  • compatible with the leading systems on the market

We have defined five Use Cases, which will be processed in the coming weeks:

  1. Processing in the event of an insurance claim
  2. spare parts logistics
  3. Container weight protection
  4. ship clearance
  5. Safeguarding sustainability

More information about the initiative founded by evan, XAIN and CHAINSTEP on COBILITY.ORG.


On the evening before the COBILITY kickoff we had the opportunity to present COBILITY, the decentralized network for transport logistics, to the Hamburg Blockchain community as part of the successful “Blockchain Mania” Meetup series with all three initiators. The invitation was also supported by the Innovation Forum Hamburg and the Digital Hub Logistics, as the location we were lucky to be able to use the recently opened coworking space “HK100” of Kravag Versicherung.

In total, we were able to present the COBILITY initiative to a good 50 guests. We used this opportunity to produce an English recording of the lectures of all three initiators. These recordings are attached, in addition there is a panel discussion where we were able to answer the very interesting questions from the audience.

After months of preparation by the organizers, on November 17, 2018, a team of more than 20 participants from startups, public authorities and Hamburg institutions set out to explore the state of digitization in Dubai and Singapore for a week or so and gather ideas for their own direction.

It was a fully packed program. We had the opportunity to talk to responsible people from administration, digitisation experts from the port industry and exciting start-ups.

A special highlight for us: both in the Dubai Chamber of Commerce and at an international pitch event in Singapore, we had the opportunity to present the concept of the COBILITY initiative. The response was excellent, which is also confirmed by the friendly vote of the COBILITY promoters (see photos below). We have learned that the idea of COBILITY has also met with lively interest in other regions of the world.

It would go beyond the scope to go into the individual topics here. Through this blogpost we would like to share some impressions from this trip.


After the successful premiere in 2017, the 2nd edition of the Blue Rocket Congress organized by DVZ took place in November 2018. The venue was Digital Logistics in Hamburg’s Speicherstadt, the home of both CHAINSTEP and COBILITY. After entertaining impulse lectures and a very interesting panel discussion, the main part of the event began. 20 different startups and initiatives were allowed to introduce themselves to the audience in a maximum of 5 minutes. If the event was overdrawn, the Blue Rocket (which interestingly has a red colour) was started.
Frank Bolten was able to present two topics: CHAINSTEP and COBILITY. The charts of the short presentation are stored here and here on Slideshare.
The impressions attached below will hopefully prove that the event was obviously a lot of fun for the participants.
