About mintBlue

mintBlue is Europe's first public blockchain platform used at scale. We make blockchain integration easy and enable organisations to focus on their product without needing to worry about the underlying blockchain infrastructure.

We offer peer-to-peer solutions to store, authenticate and monetise data. This means there is no dependency on others (sorry, Google!).

There is a clear need for a new kind of technology, built by a new kind of company. When we consider that most of the web is in the hands of a small group of powerful companies.

We are certainly not 'crypto'. Blockchain is a revolutionary technology that can change the web, while crypto is only focused on speculation and get-rich-quick schemes. We will never issue a token ourselves and want to be an authoritative, compliant cloud solution.

mintBlue started in a hackathon at the end of 2020 and today we consist of a dedicated team of 6 people, working hard to become the integrity infrastructure for an honest internet.

How we develop software

We strive to create software that is maintainable, keeps it simple, and performs well at scale. Our back-end is written in Typescript and is built upon many years of experience building back-end system. It has a modular design that makes it easy to extend functionality and expose multiple services. For communication between different services we use RabbitMQ and Redis.

We believe in eating your own dogfood. That is why we use our public SDK extensively in our own back-end and front-end to deliver features.

Our continuous integration pipeline on Gitlab allows us to run automatic tests and deploy to testing and production environments in a safe and reproducible way. We strive to automate as many parts of the software development process as possible.
