Multi-sig

A wallet that needs several private keys to approve a transaction, such as two of three signers, so one compromised key cannot move funds alone.

Multi-sig (multi-signature) is a security mechanism that requires multiple private keys to authorize a transaction, rather than just one. For example, a 2-of-3 multi-sig setup requires at least 2 out of 3 designated keys to approve any transaction. This is particularly valuable for high-value tokenized domains, where multiple parties might share ownership or where additional security is essential. Multi-sig wallets can protect against single points of failure, insider threats, or key loss. Organizations can use multi-sig to ensure that valuable domain transfers require approval from multiple executives, while individuals can use it to protect against theft or accidental loss of their domain assets.

Author

Fenwei Bian is a software developer in her thirties who spends her working hours in pull requests and her weekends with her hands in soil or sawdust. Years of open source on GitHub taught her that names are interfaces: a good one is clear, honest about what it does, and kind to whoever has to use it next.

She gardens because it rewards patience and punishes wishful thinking, and she does woodwork because a joint either fits or it doesn't. Both habits show up in how she writes about naming — measure twice, check the source, and don't sand over a rough spot and hope no one notices.

For Namefi she writes about how domain markets actually move, the practical trade-offs of tokenizing and flipping names, and picking a domain you'll still be glad you own in twenty years.

Editor

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.
