$BTC Namecoin differs from the regular Internet in that it is a decentralized alternative to the traditional Domain Name System (DNS). The main differences are as follows:
### 1. Decentralization
- Regular Internet: The Domain Name System (DNS) is managed by centralized organizations such as ICANN (Internet Corporation for Assigned Names and Numbers). Domain registrations are done through accredited registrars, which can control access to domain names.
- Namecoin: Namecoin uses a blockchain to manage the domain name system. This means that there is no single authority that manages domain registration. Instead, all domain data is stored in a distributed ledger that is maintained by a network of nodes (miners and full nodes).
### 2. Censorship resistance
- Regular Internet: Domains can be blocked or seized by authorities or registrars for various reasons, including copyright infringement, political censorship, and other legal issues.
- Namecoin: Since the domain information is stored on the blockchain, it cannot be changed without the consensus of the entire network. This makes Namecoin censorship-resistant, as no one can simply delete or change the domain name record.
### 3. Confidentiality
- Regular Internet: When registering a domain, you are usually required to provide personal information such as your name, email address, and phone number. This information may be accessible to third parties, including government agencies.
- Namecoin: Domain registration and management in Namecoin is anonymous. Users can register and manage domain names without revealing their identity.
### 4. Protection against man-in-the-middle attacks
- Regular Internet: Traditional DNS servers are vulnerable to man-in-the-middle (MITM) attacks, where an attacker intercepts traffic between a user and the server, changing or replacing information.
- Namecoin: By using cryptographic methods and decentralization, Namecoin provides protection against MITM attacks. All changes in the domain name system are verified and confirmed by the network nodes, which significantly complicates third-party interference.
### 5. Domain zone .bit
- Regular Internet: Regular domain zones, such as .com, .org, .ru, etc., are managed centrally and are subject to ICANN rules.
- Namecoin: Namecoin uses its own domain zone - .bit. Domains in this zone are registered and managed by users themselves, without the need to contact traditional registrars.
### Conclusion
Namecoin provides users with a decentralized, secure, and censorship-resistant alternative to traditional domain name systems. While Namecoin has not yet achieved widespread adoption, it demonstrates the potential for blockchain technology to solve problems associated with internet resource management.
