Cortex by Nethermind


Founded in 2017 by a small team of technologists, Nethermind builds Ethereum solutions for developers and enterprises. Boosted by a grant from the Ethereum Foundation in August 2018, the team has worked to deliver the fastest Ethereum client in the market, optimised to the very last byte.

In addition to the client, the team has built a peer-to-peer Data Marketplace, run multiple free Advanced EVM workshops to educate developers, and been actively involved with Ethereum Core development. Nethermind is based in London, UK.
