Tezos
In 2014, Arthur Breitman released two papers under the pseudonym L. M. Goodman while working at Morgan Stanley. He chose the name Tezos after writing a program to list unclaimed websites that could be pronounced in English. That same year, he registered Dynamic Ledger Solutions Inc. in Delaware as chief executive. In March 2014, he contracted French firm OCamlPro to help him conceive the protocol and develop the prototype. Arthur did not notify his employer of this work as required by FINRA regulations. The Financial Industry Regulatory Authority eventually fined him $20,000 for the violation. By 2016, he left Morgan Stanley and Tezos received $612,000 from ten backers. Kathleen Breitman joined her husband in planning an initial coin offering. They secured a $1.5 million investment from Tim Draper. A public relations firm called Strange Brew promoted their project with claims about large American financial firms using the technology.
On the 17th of April 2017, the Tezos Foundation was established in Zug, Switzerland. Arthur and Kathleen Breitman created it alongside Johann Gevers and Swiss law firm MME. The foundation planned to raise money through donations rather than selling securities. On the 1st of July 2017, the foundation raised $232 million in Bitcoin and Ethereum during one of the largest initial coin offerings ever. Kathleen Breitman compared contributions to a pledge drive where donors received tote bags. Some participants viewed these transactions as investments subject to SEC oversight. By December, assets held by the foundation stood at $820 million including the Breitmans share. The agreement stated that if the blockchain functioned for three months, the founders would receive 8.5% of the ICO proceeds plus 10% of tokens. This structure became central to later legal disputes over whether the sale constituted unregistered securities.
By October 2017, the Breitmans and Gevers were in a dispute over control of the project. The couple alleged Gevers pressured the foundation council into signing a contract giving him a bonus of $1.5 million. Gevers controlled all assets held by the foundation which reached $820 million by year end. These disagreements caused delays in deploying Tezos and triggered investor lawsuits alleging fraud. In 2018, Gevers resigned and received $400,000 while the foundation board was replaced. The Tezos Foundation paid $25 million to settle lawsuits in 2020 before federal courts ruled on the security classification issue. Arthur Breitman joined the foundation's council in 2021 after years of conflict. The legal battle highlighted tensions between decentralized ideals and centralized governance structures within early blockchain projects.
The primary protocol uses liquid proof of stake to achieve consensus among network participants. It supports Turing complete smart contracts written in Michelson language. Michelson is a purely functional stack based language with no side effects designed for formal verification. This approach allows developers to mathematically prove code correctness before deployment. The testnet launched in June 2018 followed by mainnet going live that September. The blockchain has been used for NFTs as an alternative to more energy intensive projects like Ethereum. Its design prioritizes security through reduced instruction sets and minimal computational complexity. Developers can verify contract behavior without running the full execution environment first.
Tezos allows itself to be amended through a staged process performed directly on the stored blockchain. Participants commit operations to submit proposals for intended code changes. Voting mechanisms determine whether those changes receive enough support to proceed automatically. If a proposal gains sufficient votes, the protocol updates to incorporate the new code without requiring hard forks. This self amendment capability distinguishes it from many other blockchain systems that require community splits for upgrades. The mechanism enables continuous evolution while maintaining network stability across thousands of nodes. Community members participate in governance decisions through token staking rather than simple majority voting rules.
In mid 2021 Tezos signed a sponsorship deal with Red Bull Racing that ended in December 2022. October 2021 saw the project become a sponsor of the New York Mets. February 2022 brought a multi year deal worth over £20 million annually with Manchester United. That same month Manchester United issued NFT digital collectibles on the Tezos blockchain. In 2022 the foundation launched a £1 million fund to collect NFTs by African and Asian artists. British photographer Misan Harriman curated this digital art gallery initiative. These partnerships demonstrated how blockchain platforms could integrate with traditional sports franchises and cultural institutions. Corporate adoption provided visibility beyond typical cryptocurrency circles while raising questions about environmental impact comparisons.
