Gavin Wood

Gavin Wood is a co-founder of Ethereum and the founder of Polkadot and the Web3 Foundation. In 2025, he stands out because he returned to lead Parity Technologies again and is pushing Polkadot toward its next big technical phase, including Polkadot 2.0 and JAM.

Origin and Background

Wood joined Ethereum early to help turn an idea into something engineers could actually build. In 2025, he said the original Ethereum whitepaper was more of a “vision document,” and that real “work needed to be done” to make it a full technical spec. 

After Ethereum, he went on to build tools and new networks that aimed to scale better and connect blockchains. Wood later founded Polkadot through Parity Technologies and the Web3 Foundation. 

Key Highlights

• Wrote Ethereum’s Yellow Paper, the technical reference that helped developers implement Ethereum clients. 
• Launched ETHCore, later known as Parity Technologies, in 2015. 
• Published the Polkadot white paper in 2016. 
• Co-founded the Web3 Foundation in 2017.
• Helped fund Polkadot’s early development via an ICO reported at $144M.
• Returned as CEO of Parity Technologies in August 2025 to guide strategy and rollout of the next stack.

Impact on the Industry (2025)

In 2025, Wood helped bring attention back to crypto infrastructure, which means more than just apps and tokens. Instead, it’s the base layers that make Web3 work. His return to Parity signaled a serious push to make Polkadot useful for real-world systems, not just crypto-native experiments.

Looking Ahead (2026 and Beyond)

Next, Wood’s influence depends on whether Polkadot’s next upgrades actually make building easier and cheaper at scale. If JAM and Polkadot 2.0 deliver, it could pull more builders toward multi-chain apps where different networks can work together instead of competing.
