On-chain
Describes data or actions recorded directly on a blockchain, where they are public, verifiable, and secured by the network rather than a private server.
- glossary
On-chain refers to data, assets, or actions that are recorded directly on a public blockchain. When a domain is "on-chain," its ownership and management can be verified and transferred via smart contracts—without needing approval from a centralized registrar. This structure provides greater transparency, programmability, and control to domain holders. While the underlying domain still lives in traditional DNS, its tokenized representation lives on-chain as a secure and interoperable asset.

Victor Zhou is a technology founder and standards editor focused on digital identity and trust. He founded Namefi, edits Ethereum Improvement Proposals, and previously led smart-contract architecture work at Google Labs.
His work sits at the intersection of naming, ownership, and the systems people use to establish identity online. That perspective makes him especially interested in the way names move between personal meaning, public recognition, and digital infrastructure.
For Namefi, Victor edits and writes about domains as durable digital identity: how names become ownable onchain assets, how tokenization changes custody and trust, and what naming can learn from the systems people use to establish identity online.
