The Vision

In 2014, Arthur Breitman, then a quantitative analyst at Goldman Sachs, became fascinated by blockchain technology. Observing the limitations of existing systems like Bitcoin and Ethereum (which relied on energy-intensive proof-of-work mechanisms) he envisioned a new approach: a proof-of-stake blockchain.

At the time, this was an uncharted territory, requiring both deep technical expertise and a clear understanding of the emerging domain.

The Challenge

Arthur needed a team capable of transforming a visionary idea into a concrete specification and working prototype. The project required expertise in OCaml, formal methods, and a deep understanding of blockchain technology to create a system that would be secure, scalable, and fundamentally different from existing blockchains.

Why They Chose Us

Arthur Breitman chose Titagone for our exceptional expertise in OCaml and formal methods, combined with our ability to rapidly transform research concepts into production-ready systems. Our team's experience in building reliable, secure financial infrastructure and our deep understanding of both theoretical foundations and practical implementation made us the ideal partner. The fact that we could deliver a working prototype and scale it to handle a $250 million ICO demonstrated our unique capability to bridge the gap between blockchain innovation and real-world deployment.

Our Approach

Starting in 2014, Titagone joined the project, initially through focused sprints to design and develop the prototype. Leveraging our expertise in OCaml and formal methods, we helped turn the concept into a robust, fully functional system.

By 2017, our collaboration extended to deploying the ICO (Initial Coin Offering) platform, enabling users to exchange Bitcoins and Ethers for Tezos tokens. The platform had to handle complex financial transactions reliably and securely, an immense technical challenge given the scale and novelty of the operation.

Results

  • $250 million processed through ICO platform within weeks
  • Created one of the first widely adopted proof-of-stake blockchains
  • Established Tezos Foundation and Nomadic Labs in France
  • Transformed a bold idea into secure, scalable blockchain infrastructure

Impact

This project highlights Titagone's ability to deliver high-stakes, technically groundbreaking solutions in emerging domains. By combining domain expertise, rigorous software engineering, and agile development, we transformed a bold idea into a secure, scalable, and operational blockchain, setting the stage for one of the first widely adopted proof-of-stake ecosystems.
