At BlockApps, he helped develop the company’s [STRATO](https://iq.wiki/wiki/strato) platform and served as its president and chief executive officer (CEO).[\\[1\\]](#cite-id-tjq003oyxn)​[\\[2\\]](#cite-id-u7tfdgvcnq)​\n\n## Early Life and Education\n\nJames-Lubin studied mathematics at Princeton University from 2007 to 2011, graduating with a Bachelor of Arts degree. While at Princeton, he wrote a senior thesis and worked for one of his professors for a year after graduation. He then pursued a Ph.D. in theoretical and mathematical physics at the University of California, Berkeley, from 2012 to 2015.[\\[3\\]](#cite-id-ba7btpuy45)​[\\[1\\]](#cite-id-tjq003oyxn)​\n\nFrom September 2011 to June 2012, he worked as a scientific programmer at Princeton’s Lewis-Sigler Institute. Before entering graduate school, he had also worked in web and mobile startups, experience he later drew on while developing software for [Ethereum](https://iq.wiki/wiki/ethereum).[\\[1\\]](#cite-id-tjq003oyxn)​[\\[2\\]](#cite-id-u7tfdgvcnq)​\n\n## Career\n\n### Ethereum\n\nJames-Lubin joined [Ethereum’s](https://iq.wiki/wiki/ethereum) early development in 2014. In January of that year, his father, Joe Lubin, sent him articles about the project from Miami during the [Bitcoin](https://iq.wiki/wiki/bitcoin) conference at which [Vitalik Buterin](https://iq.wiki/wiki/vitalik-buterin) first publicly announced [Ethereum](https://iq.wiki/wiki/ethereum). James-Lubin decided to join the project on March 22, 2014, and spoke with Buterin two days later.[\\[2\\]](#cite-id-u7tfdgvcnq) That summer, James-Lubin traveled with his father to Zug, Switzerland, where he witnessed a leadership dispute later called the “Red Wedding.” He recalled that the conflict involved internal political maneuvering and serious legal issues; during it, Buterin decided to remove [Charles Hoskinson](https://iq.wiki/wiki/charles-hoskinson) and [Amir Chetrit](https://iq.wiki/wiki/amir-chetrit) from leadership positions.[\\[2\\]](#cite-id-u7tfdgvcnq)​\n\nBeginning in September 2014, James-Lubin worked with Jim Hormuzdiar on a Haskell-language Ethereum client. James-Lubin brought experience from web and mobile startups and advocated for a REST API—an interface that would let developers build applications using [Ethereum](https://iq.wiki/wiki/ethereum). He recalled that some developers in the cypherpunk-oriented community were wary of server-based approaches, and that the proposal met with suspicion.[\\[2\\]](#cite-id-u7tfdgvcnq)​\n\n## BlockApps\n\nJames-Lubin is the founder and CEO of BlockApps which developed [STRATO](https://iq.wiki/wiki/strato), an Ethereum-based enterprise [blockchain](https://iq.wiki/wiki/blockchain) platform. Before moving full time to the business side, James-Lubin architected and implemented major parts of the product, including its RESTful API, authorization framework, peer-to-peer networking code, Node.js client, and third-party integrations. His responsibilities also included maintaining and growing the company’s business.[\\[3\\]](#cite-id-ba7btpuy45)​[\\[1\\]](#cite-id-tjq003oyxn)​\n","categories":[{"id":"people","title":"people"}],"tags":[{"id":"Founder"},{"id":"Developer"},{"id":"Ethereum"}],"images":[{"id":"QmUfPiS7hsb5hFeuoqTzeby1SFmUeqfS8wRgtVxf2AcJbp","type":"image/jpeg, image/png"}],"media":[],"metadata":[{"id":"references","value":"[{\"id\":\"tjq003oyxn\",\"description\":\"LinkedIn: Kieren James-Lubin\",\"timestamp\":1794483932937,\"url\":\"https://www.linkedin.com/in/kjameslubin/\"},{\"id\":\"u7tfdgvcnq\",\"description\":\"Early Ethereum Days - Kieren James-Lubin\",\"timestamp\":1794483938635,\"url\":\"https://www.earlydaysofeth.org/people/kieren-james-lubin/\"},{\"id\":\"ba7btpuy45\",\"description\":\"Princeton Graduate - Kieren James-Lubin '11\",\"timestamp\":1794483953835,\"url\":\"https://gradfutures.princeton.edu/grad-stories/kieren-james-lubin-11\"},{\"id\":\"ke4mijkk1k\",\"description\":\"Fitz Gate - Kieren James-Lubin, Co-Founder & CEO\",\"timestamp\":1794483973935,\"url\":\"https://fitzgate.com/portfolio/blockapps/\"},{\"id\":\"59cp5s8uju\",\"description\":\"Podcast - Kieren James-Lubin\",\"timestamp\":1794483986899,\"url\":\"https://www.podchaser.com/creators/kieren-james-lubin-107tjKkYgE\"}]"},{"id":"linkedin_profile","value":"https://www.linkedin.com/in/kjameslubin/"},{"id":"github_profile","value":"https://github.com/kjameslubin"},{"id":"twitter_profile","value":"https://x.com/kjameslubin"},{"id":"main-image-origin","value":"{\"imageId\":\"QmUfPiS7hsb5hFeuoqTzeby1SFmUeqfS8wRgtVxf2AcJbp\",\"originalId\":\"QmUfPiS7hsb5hFeuoqTzeby1SFmUeqfS8wRgtVxf2AcJbp\"}"},{"id":"commit-message","value":"Add Kieren James-Lubin wiki"}],"events":[{"type":"DEFAULT","title":"Joined the Ethereum project","date":"2014-03-01","description":"James-Lubin decided to join Ethereum.","link":null,"multiDateStart":null,"multiDateEnd":null,"id":"bb748890-b8a0-4c3b-9644-3890fdcbfe30"},{"type":"DEFAULT","title":"Spoke with Vitalik Buterin","date":"2014-03-01","description":"James-Lubin spoke directly with Vitalik Buterin about Ethereum.","link":null,"multiDateStart":null,"multiDateEnd":null,"id":"092027a4-bf81-45de-a3bb-f9c7ed1fa823"}],"linkedWikis":{"founders":[],"blockchains":[],"speakers":[]},"user":{"id":"0x8af7a19a26d8fbc48defb35aefb15ec8c407f889"},"author":{"id":"0x4a2bc97afbf41a2cbf4b4628f63420682ff4cf2a"},"language":"en","operator":{"id":"0x4a2bc97afbf41a2cbf4b4628f63420682ff4cf2a"}}
