Our Story

Agile software developers and consultants specialized in building end-to-end custom products. We provide cryptography, blockchain, data science, web applications, and machine learning solutions.


These days, it’s not enough to be exceptional with the available technologies like Go, Rust, Hyperledger, or Java.

That’s we’ve built Aleph Zero and brought it to market. It’s a state-of-the-art, peer-reviewed consensus protocol that we use to deploy custom blockchain solutions that require high scalability and energy efficiency.

We want to fit the technology towards your specific needs and industry. We’ve learned to do that perfectly at:

What We Do

End-to-End Solutions

We can help you to maintain your current project or build a new one from scratch. We combine Agile execution with academic precision.

From the idea, through research, to development and product launch.

Cardinal Cryptography is an end-to-end partner for disruptive industries. And unlike other software houses—we live and breathe distributed networks.

Blockchain Development

We are the creators of Aleph Zero but we know everything about Ethereum, Corda, Hyperledger, and other blockchains. Reach out with an idea for a distributed application, smart contracts development, or protocol implementation.

Custom Software Development

With expert skills in Python, Golang, Solidity, Java, and JavaScript, we can deploy any custom software you need. Tell us about your project and we’ll take it from there.

Product Design

We know the challenge of innovating and going to market. You can rely on us and save yourself the headaches. We develop brands, products, and build go-to-market strategies.

Dedicated R&D Teams

The number of talent on the market is limited, especially within top tier experts. We’re far from selfish, so you can hire our academic team to assist you in the research and development of your ideas.
