# Joseph Lubin

> Joseph Lubin is the co-founder of Ethereum and founder/CEO of ConsenSys, the most influential Ethereum software company in the world. A Princeton-trained engineer who spent years at Goldman Sachs before pivoting through a Jamaican music production detour to become one of crypto's most consequential builders, Lubin methodically constructed the plumbing of the Web3 internet — MetaMask, Infura, Truffle — while most people were still debating whether blockchain was real. As of 2026, he chairs SharpLink Gaming's mission to build the world's largest publicly-traded ETH treasury, and warns loudly about centralized AI's threat to democratic society.
