Stephan Noller, Ubirch CEO: "We are overwhelmed by the different application examples of the participating startups. The companies' proposals, especially those of the three winners, have convinced us that the topic of data integrity is more than just a niche topic in the field of cybersecurity. The Ubirch Startup Chal-lenge has proven that there are many visionaries and pioneers who are bringing our platform into concrete application and making data integrity a matter of course in corporate processes."

Ubirch's digital evidence and data integrity technology complements Minechain's value proposition for the reliability and traceability of information for the energy commodity supply chain, especially contributing to the digital certification of Green Hydrogen, to measure and certify the reduction of carbon emissions from industries. This will increase the sustainability of global and local value chains, and economic diversification, and will contribute to the energy security of Germany and the European Union."
