Joseph “Joe” Lubin is a co-founder of Ethereum and the founder and CEO of ConsenSys. Ethereum’s history identifies Lubin as an early co-founder who helped fund the project’s early stages; ConsenSys describes his later work building software and infrastructure around Ethereum. These roles are related, but Lubin should not be described as the sole creator or technical author of Ethereum.
Early Ethereum Role
Lubin joined Ethereum’s early founding group in 2014. Ethereum’s history describes his contribution as helping fund the project’s early stages. The Ethereum protocol was built by a wider group of founders, researchers, and developers; the project’s history also credits Vitalik Buterin and other co-founders with distinct roles.
ConsenSys
Lubin founded ConsenSys in 2014. The company develops products and infrastructure used across the Ethereum ecosystem, including the MetaMask self-custody wallet, Infura developer infrastructure, and Linea, an Ethereum Layer 2 network. These are commercial products and services; they are not all components of the Ethereum protocol itself.
Current Role
ConsenSys identifies Lubin as its founder and CEO. The company’s portfolio has changed over time, so older product counts, user figures, and claims of market dominance should be dated and tied to a specific source rather than repeated as current facts.
