The Web3 Foundation is a Swiss nonprofit established in 2017 in Zug, Switzerland by Gavin Wood — Ethereum co-founder, author of the Ethereum Yellow Paper, and creator of the Solidity programming language. The Foundation funds research and development of the decentralized web (“Web3”), primarily through its flagship project: the Polkadot blockchain ecosystem. Polkadot’s DOT token, the Kusama canary network (KSM), and the Substrate framework for building custom blockchains were all conceived and initially funded by the Web3 Foundation. Parity Technologies (Gavin Wood’s separate company) handles core engineering, while the Foundation governs grants, token distribution, and ecosystem development.
Background
Gavin Wood coined the term “Web3” in a 2014 blog post describing a decentralized internet where users control their data, identities, and assets without relying on tech monopolies. After leaving Ethereum in 2016, Wood founded Parity Technologies and the Web3 Foundation to build Polkadot — a “blockchain of blockchains” that would enable interoperability between specialized chains (parachains).
Polkadot and the Parachain Model
| Component | Description |
|---|---|
| Relay Chain | The central Polkadot chain providing security and consensus for all connected parachains |
| Parachains | Sovereign blockchains connected to the Relay Chain, sharing its security |
| Parachain Auctions | Parachains lease slots by locking DOT — determined via candle auction |
| Bridges | Cross-chain connections to external ecosystems like Ethereum and Bitcoin |
| Substrate | Modular Rust framework for building Polkadot-compatible (or standalone) blockchains |
| Kusama | Polkadot’s canary network — same architecture, faster governance, higher risk tolerance |
W3F Grants Program
The Web3 Foundation runs one of the most active blockchain development grants programs, funding hundreds of projects across Polkadot, Kusama, and the broader ecosystem — covering research, developer tooling, wallets, bridges, and protocol development.
OpenGov
Polkadot migrated to OpenGov — a fully on-chain, multi-track governance system where DOT holders vote on referenda across multiple tracks (Treasury proposals, Runtime upgrades, Emergency actions) with no council or technical committee, creating one of the most decentralized on-chain governance systems in crypto.
