Infrastructure Engineer, Blockchain
Liam Horne is an English-born, Canadian-raised software entrepreneur and engineer who has spent his career building Ethereum scaling technology, from state channels to Optimism and Base, and is now building Tempo, a payments-focused L1 blockchain.
About Liam Horne
Liam Horne studied Computer Science at the University of Waterloo before dropping out to start a startup. He spent most of his twenties working on Ethereum technology, beginning with scaling payments via state channels (building projects like Web3Torrent), then pivoting to build Optimism, one of the defining projects of the Layer 2 rollup ecosystem, and co-launching Base with Coinbase on the OP Stack. Around 2023 he shifted focus to stablecoins, writing and working on projects such as World Chain, Stable, and Build Canada: Crypto after observing that Tether on Tron dominated real-world stablecoin usage despite Ethereum scaling efforts. This work led him to Tempo, a payments-first infrastructure L1 blockchain project he is currently building and hiring for. He is also an active startup investor, having invested in companies including Othership, QA Wolf, Daimo, Erebor, Stable, Farcaster, Ambrook, Mercantile, Software Applications Incorporated, Conduit, Splits, Axiom, OpenSea, Agora, and Flex.
