In May 2025, Joseph Lubin was appointed to Sharplink's Board of Directors and named our Chairman. He is a co-founder of Ethereum and the founder of Consensys, a full-stack, global blockchain company. Joseph has established himself as a guiding force in the fast-growing blockchain industry and a powerful advocate of decentralized technology. Born and raised in Toronto, Joseph graduated from Princeton University with a degree in Electrical Engineering and Computer Science. He worked in the Princeton Robotics Lab at Tomandandy Music developing an autonomous music composition tool and at private research firm Vision Applications Inc. building autonomous mobile robots.

Inspired by Satoshi Nakamoto’s Bitcoin white paper and the potential of distributed systems to “shatter the silos of power and re-balance the information asymmetries that disadvantage so many” Joseph delved into the incipient blockchain community. He was a primary figure in the creation and launch of Ethereum alongside fellow Torontonian Vitalik Buterin in 2014, and eventually moved to build an ecosystem around the nascent technology, in part by launching Consensys.
