A genuinely decentralised, extremely cheap and censorship-resistant registry for .bit names with no company and no recurring fee, but it demands technical setup (wallet, manual name ops, ncdns/TLS), names expire without renewal, and its security and liquidity depend on the Bitcoin ecosystem and thin NMC markets.

Namecoin is a decentralized naming system launched in 2011 that lets you register .bit domains on a blockchain merge-mined with Bitcoin. It operates as an open-source, community-run project with no company behind it. You interact directly with the blockchain using a wallet, paying a one-time 0.01 NMC fee plus a variable transaction fee. The main caveat: it’s technically complex, adoption is minimal, and names expire if not renewed.
You don’t rent infrastructure - instead, you register and manage .bit names directly on the Namecoin blockchain. The system uses SHA-256 and is merge-mined with Bitcoin via AuxPoW. You interact through tools like Namecoin Core or Electrum-NMC, and resolve .bit domains using ncdns. You get full control over your name’s key/value data (up to 520 bytes), but no hardware, hosting, or cloud mining is involved. You do not get a traditional domain registrar experience or customer support.
Name registrations are perpetual until expiry, with a semi-expiry after ~222 days (31,968 blocks) and full expiry after ~250 days (35,000 blocks total). There’s no maintenance fee, but you must pay a dynamic transaction fee to renew or update. The initial registration requires a 0.01 NMC fee (destroyed, not collected). No refunds are possible - on-chain operations are irreversible. There is no trial period, and the 12-block commit-then-reveal process adds delay.
Yes, full on-chain proof exists: all name records, ownership, and expiry states are verifiable on the Namecoin blockchain, which is open-source and merge-mined with Bitcoin via AuxPoW. A 51% attacker could reverse a name registration, but otherwise, security is tied to Bitcoin’s hash rate. The system doesn’t rely on any central party - what you see on-chain is the truth. However, you must run or trust a node to verify it independently.
Namecoin has operated since 2011 with no fraud, exploits, or operator scams. It’s run by an international team of volunteers and academics, funded by grants from NLnet, the Tor Project, and others. While technically sound, adoption is extremely low - reddit users describe its concept as “failed” but still value its censorship-resistant registry. The lack of a legal entity means no accountability, but also no central point of failure. Data quality is verified, but use caution due to thin markets and technical barriers.
The cost to register a .bit name is a one-time 0.01 NMC fee (currently ~$0.01) plus a dynamic transaction fee paid to miners. Renewals and updates only require the transaction fee. You must pay in NMC, which you acquire from exchanges like CoinEx (though access is now restricted in some regions). There’s no fiat payment option or KYC - just a wallet and on-chain transaction. The real cost is the transaction fee, which fluctuates based on network demand.
Namecoin is a legitimate, decentralized .bit naming system with no recurring fees or corporate control, ideal for privacy-focused users who understand blockchain mechanics. However, it’s not beginner-friendly, requires ongoing technical maintenance, and offers no support or recovery if you lose access. For most, buying a traditional domain is simpler - use Namecoin only if you need censorship resistance and accept the risks.

| Notes | The registration fee is 0.01 NMC and is destroyed by the transaction ('nobody gets them'); the transaction fee is dynamic and set by miners. There is no registration fee for renewals or updates, only a transaction fee. At NMC ~$1.02 (2026-09-24) the 0.01 NMC fee is about one US cent. Registration uses a commit-then-reveal flow (pre-registration of a salted hash) with a mandatory 12-block minimum delay. Names semi-expire after 31,968 blocks (~222 days) without renewal/update and fully expire after an additional 4,032 blocks (~28 days), after which anyone can re-register. Name values are limited to 520 bytes. A variable USD figure is not recorded because the real cost is the dynamic transaction fee. |
