A ccTLD (country-code top-level domain) is a two-letter TLD assigned to a country or territory based on the ISO 3166 list — .uk, .de, .jp, .io (British Indian Ocean Territory), and so on. Unlike a gTLD, a ccTLD is administered under the authority of its country rather than directly by ICANN contract, so each one sets its own eligibility, pricing, and policy rules — some require local presence, others (like .io or .co) sell globally.

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.
