  1. Ubirch and IBM have a partnership with IOTA. The technology that will be used in this vaccination-ID is already used at several airports in Germany. IOTA and a few other utility blockchains by Ubirch are used there.

  2. As a German: No we won’t. They might develop the technology, but we won’t be able to use or implement it, just beacuse we are literally a developing country when it comes to technology. I’m not even joking. 8 years ago our soon-to-not-be chancellor called the Internet “new territory” and she mostly got agreed with. Not much happened since then.


    Just telling you this so you ppl don’t get your hopes up too high about a possible implementation.


    LMAO i just imagined how they will explain blockchain technology to people who don’t even understand the Internet. There is a not so tiny amount of people who don’t know what a Link is.

  3. For a bit more context: Ubrich is using IOTA to store vaccination certificates on the tangle (the IOTA equivalent of the blockchain). The system is already running for weeks or even months at several German airports and local test centers and its running quite smoothly at very low cost/test

    Here is a related article to the system already in place: [](

  4. As a german: this kind of innovation is extremly surprising for Germany, Germany is usually way behind new technology, but in the pandemic, we somehow embraced things like an opensource privacy focused covid-19 warnapp and now this

  5. Summary: its not quite clear which blockchain is used, only that said company Ubrich has the biggest Investment in the tech (51% of funds went there) and IBM helps out, its said that they would get a vaccine-certificate that is saved on 5 blockchains run by Ubricht, what ever that means… they also assure its private and secure, as well as you will be able to look it up yourself later via a Website or something

  6. That’s great to see some adoption. But the most important thing is to see what kind of problems/ situations will accrue during this development. To get this kind of feedback will help to improve projects like IOTA a lot!

  7. You’re not allowed here because you didn’t get the vaccine.

    “But I already had covid so I have the antibodies.”

    You’re not allowed here. You didn’t get the vaccine.

    Health ministry’s “secret competition”: Ubirch and IBM win bid for digital vaccination certificate

    The Federal Ministry of Health had written to 29 companies as part of a “negotiated procedure without a competitive bidding process”, which was initially also designed as a “secret competition”. The aim was to find the best offer for a digital vaccination certificate for all those vaccinated against Covid-19. The bidding period was just five days, and seven companies took part. The contract was awarded to the Cologne-based company Ubirch (51 percent) with its blockchain-based system and IBM (49 percent), as SPIEGEL learned from Ubirch.

    A digital vaccination certificate already exists in Israel. In China, certificates showing vaccinations and test results have been available via the WeChat online service since Monday. The EU Commission plans to present draft legislation on March 17 for a “digital green passport” that would include details of Corona vaccinations, Covid 19 disease and negative tests, making it easier to lift travel restrictions. The German solution is intended to be compatible with European requirements.

    Technically, the Ubirch system works like this: Every vaccinated person receives a QR code at the vaccination center or from their family doctor – on a plastic card or piece of paper, by mail or app. The QR code is an anonymous fingerprint generated from personal data such as the name and details of the vaccination date and the vaccine used. It is cryptographically signed and stored in a total of five blockchains.

    When the QR code is scanned, for example when crossing a border or during an access control to an event, the system only queries whether there is an entry in the blockchain of the Ubirch system that matches the QR code. Thus, no personal data is visible and matched. For the controlling person, it only becomes visible – in an app or on a verification website – whether the digital fingerprint is in the Ubirch blockchain. If it is, it means the person being controlled has been vaccinated.

    The biggest advantages, according to Ubirch, besides data protection, are speed and protection against forgery. Entries in the classic yellow vaccination certificate are often difficult to decipher and easy to forge, he said. However, security researcher and journalist Hanno Böck had managed to outsmart the Ubirch system with fake QR codes, albeit with certain limitations. The problem is now said to be fixed.

    Up and running in eight weeks

    Ubirch CEO Stephan Noller told SPIEGEL, “I think it’s cool that this time it’s not just some established big tech company providing the solution, but a smart combination of big tech and startups.” Ubirch is working with Govdigital, a cooperative of 15 state and local government IT service providers and the Bundesdruckerei. Noller also considers the combination a startup, just “a municipal one.” Govdigital provides one of the blockchains used.

    Among other things, Noller said IBM will develop more apps for the system and push to connect the system to doctors’ offices.

    So far, the Ubirch system is being used in only two counties: Altötting in Upper Bavaria and Zollernalbkreis in Baden-Württemberg. Within eight weeks, according to the Ministry of Health, it is to be operational nationwide.

    According to the invitation to tender, the contract has a total volume of 2.7 million euros.

  9. IOTA (one of the systems being used here) is *not* a blockchain. Its a distributed ledger, which blockchains also are, but it works using a directed-acyclic-graph rather than a chain of signed blocks!

    We really need to kill “blockchain” as a stand in for DLT (distributed ledger technology) / cryptocurrencies. It only really caught on because of Bitcoin and 99% of people care about what these things *do* rather than how they *work*.

    Its like calling cars internal combustion engines. Its strange conceptually, and outright wrong when talking about a Tesla!

  10. Was just thinking about how serendipitous it is that we are in a situation where authentication of those who have been vaccinated is of paramount importance….

    All while a “magical internet ledger” (i.e. blockchain) is becoming widely accepted and mainstream, which requires no individual trusted authority….

    Distributed ledgers were MADE for this moment in history, and I personally think it will catapult blockchain / DAG technologies into our culture permanently.

    TLDR – this is good for ‘bitcoin’
