ccTLD (Country-Code Top-Level Domain)

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. Those rules also shape whether and how a ccTLD can support an on-chain ownership layer: a registry that is open to tokenization makes a domain easier for Namefi to represent as a wallet-controlled asset.
