Arthur Breitman is a computer scientist and applied mathematician from France who gained strong knowledge of qualitative finance and robotics. His curiosity and interest increased with blockchain technologies, where he made a name for himself creating Tezos, a layer-1 blockchain technology aimed to address the blockchain trilemma.

Who is Arthur Breitman? Qualitative Finance to Blockchain

Arthur Breitman’s programming career started at the age of 18 when his interest in finance and programming was sparked, leading to creating programs for trading algorithms in stocks. At such an early age, he bagged an award in France at the International Olympiad in Informatics.

Following his passion, Arthur eventually attended École Polytechnique in France, where he studied applied mathematics and computer science. He later earned a Ph.D. in computer science from the Courant Institute of Mathematical Sciences at New York University.

After his Ph.D degree, he worked with Goldman Sachs as a qualitative analyst and vice president of Morgan Stanley. On leaving Goldman Sachs, he co-founded his own company, Dynamic Ledger Solutions (DLS), with his wife Kathleen Breitman.

He later worked with Google X and Waymo as a researcher before making the switch to blockchain, driven by his growing interest in blockchain technologies, which he found lacked innovation while striving to remain decentralized.

A Solution to Blockchain Trilemma – Tezos

Based on his idea of solving blockchain’s trilemma problems, Arthur and Kathleen Breitman began working on blockchain solutions with hopes of providing solutions based on security, efficiency, and adaptability to evolving technologies and trends.

They named their blockchain technology Tezos, a layer-1 blockchain technology designed to address scalability issues plaguing Ethereum. This technology gained strong attention due to its innovative approach and potential in the blockchain industry.

In 2017, Tezos conducted an Initial Coin Offering (ICO) and raised over $232 million, making this ICO event the biggest ever in the blockchain space at the time. However, the project faced strong controversies over time, with Johann Gevers, head of Tezos Foundation.

Following a lengthy dispute and suspicion from investors, Fever resigned in 2018, receiving a payout of over $400,000. The Tezos Foundation underwent replacements and finally launched on the blockchain.

However, Tezos has continually faced legal challenges that have prevented its project from reaching the heights it was once expected to. In 2020, the Tezos Foundation reached a settlement fee of around $25 million with the federal court for ICO sales of unregistered securities.

Since then, Tezos Foundation has continued to grow under the leadership of Breitman and his team, aligning its vision with the broader focus of the blockchain space.
