Using Blockchain To Solve Real World Problems – Interview With Ubirch CEO, Karim Attia



Image Credit:

Ubirch is a German-based company using blockchain to solve real-world problems globally. The company is utilizing blockchain in innovative ways across several industries. By providing secure, portable, and immutable data, Ubirch is one company showing the world just how ground-breaking blockchain is. 

Surprisingly, the company started in a garden. Founder and Co-CEO Stephan Noller, connected a birch tree in the garden to the internet with an IoT (internet of things) device he designed. Mentioning the name of the tree in a tweet, caused lights on the tree to glow. The company has since been able to link data generated physically to the digital world, efficiently and securely.

With the company on the verge of being a global provider of digital trust, Karim Attia, CEO of Ubirch, will be taking us on a journey of how Ubirch is using blockchain and cryptography to provide digital trust, integrity, and security. 

How important is blockchain to Ubirch?

Blockchain is a key component for Ubirch in the provision of data that is trustworthy. On a global level, trust becomes very important, and this is where the importance of blockchain comes in. It is a distributed ledger which means no one can tamper with the information on it.  

This is one of the many positive effects of this new technology. Once something has been written in there it is there until the end of time. Therefore, we are using this technology for our trust services. 

We have developed a layer between the public blockchains and our infrastructure which gives us an extra edge in terms of scalability and efficiency. Hence, we can make public blockchains faster at the same time very cost-effective.

Verifying COVID-19 tests results with blockchain, blockchain-on-a-Sim and other applications by Ubirch

Health certificates are becoming more and more important in everyday life. There’s an increasing need for people to prove that they are not infected with COVID-19 or in the future prove that they have been vaccinated. The ability to prove this could be a prerequisite for granting travel permits or even work permits. 

One of the many solutions Ubirch is providing is making sure that these health certificates are not falsified. The test and vaccination status is assessed at the test centre or vaccination centre. We make it easy to verify certificates globally with public blockchains. 

Recently, together with known partners, Ubirch has been able to implement a blockchain client on a Sim Card – a project we are very proud of. Now, any sim card enabled device will be able to use our trust service. It is a very big achievement and we are the only company worldwide, as far as we know to achieve such a feat. 

The Ubirch infrastructure is also being used to provide data that helps women track their cycles and know their fertile time window. The device is created by German startup, Trackle. Trackle is one of our first clients. They are using our infrastructure to make sure that specific temperature data gathered by the device specially designed for women is correct. This data is used to assess fertility rates, supporting women naturally in their family planning efforts. 

Level of blockchain adoption

In Europe, most people think of blockchain as bitcoin, it is still very much associated with cryptocurrency in people’s minds. The other benefits of this revolutionary technology haven’t really caught on in Europe. It takes a lot to convince people of the benefits of blockchain, people usually conclude that you are trying to sell them bitcoin. 

However, it is getting better gradually. We are partnering with a group of data centres across Germany that are providing a local governmental blockchain to support the digital transformation of administrative processes. They are getting it and they are seeing that blockchain has more benefits beyond cryptocurrencies. 

Interestingly, the opportunities of the blockchain ecosystem are the motivation of our team at Ubirch. The enthusiasm emanates from the belief that we are shaping the future. We are setting the pace for entirely new data-driven business models.

Challenges to using blockchain technology

One of the challenges is to identify the right industry and sector that will really benefit from blockchain in the short term. There are sectors where you do not see the benefits of blockchain immediately. So knowing the industry and sector that will benefit from the technology at a sprint is a major challenge. 

For us, however, it is healthcare, insurance, logistics, energy, smart cities, and industry. These sectors are benefiting most from the solutions we offer. 

Ubirch’s plans for Africa?

Soon, we will have the same capabilities we have in Europe, in Africa. Ubirch is happy to support regions within Africa with our knowledge and expertise. There are a lot of ways in which Africa can benefit from blockchain and the solutions we provide. 

Healthcare, supply-chains, real-estate amongst others, are areas where our infrastructure will be beneficial for the continent. 

The future of blockchain. 

Blockchain will be a fundamental part of our lives soon. A lot of things will depend on blockchain infrastructures such as the ones we provide. 

It is already evident from the way it is transforming the financial sector. It will eliminate the need for intermediaries. Blockchain will be a trustworthy global technology on which activities of different sectors will be organized.

How blockchain can bridge the trust gap in governance



Governments and authority figures have existed throughout history to serve many purposes amongst which trust is central. In matters of social and economic concern, some form of trust and/or distrust has enabled people in all cultures across all times to transact and interact, to exchange value and advance cultural agenda. This is so important that our very concept of money is built on trust or value induced by trust.

However, for most of history up till now, authorities have wielded central power and that has always been an avenue for corruption, a lack of transparency which leads to wastage of resources and spirals down to a lack of trust by a populace in the authority over them. Evidently, this is paradoxical, the governments are to be trusted by virtue of the authority given to them but it’s this centralization that ends up upending it down the line.

Evidently, many people in many countries do not trust governments to do things the way they say they’d do them. The question is, what can a hypothetical government do about massive distrust from citizenry?

Enter the blockchain. As with many things, technology often has something to offer. The blockchain which underlies cryptocurrencies like most famously, Bitcoin, has been imbued with a certain peculiar philosophy; one of democratization. Although this is more of a mantra within crypto circles, it’s not difficult to see why. First is the blockchain’s nature; distributed ledger built on cryptography with certain features which make it functionally immutable. It’s most famous and defining uses have been with crypto but it could be so much more. A record keeping system for example, one that would be immutable and most importantly, transparent, open to all to see.

So, in the administration of nation states, blockchain technology has the ability to fit into a lot of places. The main idea is to be able to carve out trust from distrust i.e. the apparent reality of being watched and having all records secure is an incentive for governments to act transparently. In some use cases, governments (as well as private businesses of course) could leverage smart contracts, a task built into a blockchain that’s executed when the conditions specified are met. These systems in governance would undoubtedly improve transparency, cut down on corruption as well as its accompanying wastes and overall be more efficient.

So, will we see a trend where governments would like to use blockchain technology? Overall, this is for now unlikely. World governments, it would seem, do not understand blockchains very well and hence are apprehensive about them even to the point of banning the cryptocurrencies built on them. At the end of the day, the use of blockchain at the governmental level of any nation depends on the nation’s own unique set of problems and issues. All in all, the next few years will be interesting no doubt in this regard.

TON OS  has more features than the Ethereum Virtual Machine and is designed as a decentralized operating system capable of handling decentralized applications. TON OS also has a stack of components that can be used by developers to create powerful applications. By making these components Open Source, anyone or everyone can view and copy fragments of the code.

The contest is open to all Africa Blockchain enthusiasts, newbies, artists, developers, policymakers and students. There is a prize of over 62,000 TONs up for grabs for the winner. The contest is open to the 54 countries in Africa for participants to build Blockchain Applications on Free TON. The aim is to add value to the FreeTON Network and the continent will equally benefit from the applications.  

According to John Kanyiri, FreeTON Africa Representative and the FreeTON Africa Team, “… we once again look forward to identifying projects culminating from this hackathon as being not only a showcase of what Africa can offer the global blockchain space but also solutions to the continent’s challenges. The creativity, ambition and sophistication of our localized developers are quite evident in the Hackathons and this time around we hope to see the same. Discovery of new talent and exposure of the same from very remote locations of Africa was witnessed in the last Hackathon and we look forward to the same this time too.”

The Hackathon is open to covering aspects of the blockchain that academia needs to know giving ample information about how the blockchain works and the current and future applications needed to change the world from the blockchain Point of View. The contest is open to both newbies and experienced developers as some of the best technical experts in the blockchain community will be there to aid you. In other words, the event is open to all who seek blockchain knowledge. 

The contest will be carried out in three sections: country competition, regional competition, and continental competition. The country and regional competitions will be held virtually however, winners of the regional competitions will get an all-expense-paid trip to South Africa for the Finals. The winners will attend the Grand Finale which will be hosted in South Africa. Participants are allowed to work on topics or applications that are peculiar to the needs of the African continent. However, some applications may include: 

  • National voting platforms
  • Fintech infrastructure/Digital Wallets (to help those who do not have access to banking)
  • Land ownership and registry
