Tezos was first conceptualized in a white paper published in September 2014 by Arthur Breitman, writing under the pseudonym L. M. Goodman. Arthur and his wife, Kathleen Breitman, founded Dynamic Ledger Solutions to develop the Tezos protocol. After several delays, the Tezos mainnet launched in 2018. A token sale in July 2017 raised 65,681 BTC and 361,122 ETH, totaling approximately $232 million at the time, marking one of the largest initial coin offerings (ICOs) in blockchain history. Since its launch, Tezos has continued to evolve, with its community actively participating in governance and contributing to the platform’s ongoing development.
