Gavin Wood is a co-founder and former chief technology officer of Ethereum, and the founder of Parity Technologies and the Web3 Foundation. 

Wood met fellow ethereum co-founder Vitalik Buterin in 2013 and helped develop the first functional implementation of the blockchain, PoC-1, which was released in January 2014. Wood is also credited with the invention of smart contract programming language Solidity, with which Ethereum is written.

Wood departed from Ethereum in 2015 and co-founded Parity Technologies, a company dedicated to building open source infrastructure atop the Ethereum network. Parity has produced a free platform with tools including mining client software, a downloadable wallet, a framework for building blockchains and a testing environment for new decentralized apps (dapps).

Additionally, Wood is the president and founder of the Web3 Foundation, an initiative that advocates for a decentralized internet in which users are in control of their data and identity. In 2019, Wood and the foundation created Polkadot, a project intended to connect blockchains and networks without the need for trust to enhance their security.

In May 2020, Wood said the Polkadot network was almost ready for launch.
