World Broad Net and hypertext markup language (HTML) inventor Tim Berners-Lee stated that if he have been constructing a website title service (DNS) immediately, he would make it “extra decentralized.”
Talking at ETH Prague on stage alongside Ethereum co-founder Vitalik Buterin, Berners-Lee mirrored on early web structure selections.
“If I may return […] I might make it extra decentralized,“ he stated.
DNS was invented in 1983 by Paul Mockapetris, changing the earlier hosts.txt file-based system with a scalable, distributed system for naming IP addresses. Nonetheless, whereas Berners-Lee was not personally liable for DNS improvement, he may have opted for a URL construction not tied to the DNS we all know immediately, or he may have pushed for a decentralized different.

Centralization of the DNS
The DNS system is extremely centralized, notably at its prime ranges of hierarchy. The foundation zone, which governs top-level domains similar to .com and .org, is managed by the US-based nonprofit Web Company for Assigned Names and Numbers (ICANN).
Moreover, essentially the most authoritative servers are operated by a handful of organizations, additional centralizing the system. This enables for simple censorship and management by governments that may unilaterally seize or block domains.
This diploma of centralization additionally makes outages as a consequence of centralized service disruption extra probably. Management over root zones and area insurance policies can be concentrated in a number of areas and amongst a choose group of stakeholders.
There are additionally issues round privateness as a result of centralized DNS queries might be monitored, logged and intercepted by web service suppliers and different intermediaries.

Crypto’s resolution to the issue
Decentralized options to the DNS system are being developed. Probably the most well-known of them is the Ethereum Title Service (ENS), which maps human-readable names to Ethereum addresses, content material on the Inter-Planetary File System (IPFS), or different information.
One other different is Unstoppable Domains. Its system mints domains as non-fungible tokens (NFTs) on Ethereum and Polygon.
ENS has seen a fair proportion of adoption. In late 2024, ENS Labs additionally partnered with PayPal and Venmo, sparking hypothesis about how this partnership is more likely to enhance mainstream adoption.
IPFS runs on Ethereum good contracts and goals to be user-owned and censorship-resistant. Presently, it’s primarily utilized in Web3 purposes, wallets and decentralized web sites.
One other different is Handshake (HNS), which goals to be a decentralized and permissionless naming protocol that’s appropriate with conventional DNS. One other undertaking with an analogous intention is Namecoin (NMC), an early Bitcoin fork designed particularly to supply .bit domains and retailer DNS information onchain with censorship resistance.
IPFS can be accompanied by its personal Inter-Planetary Title System (IPNS), which permits mutable naming for IPFS addresses (hashes). URLs generated this manner level to particular content material, not servers.
A non-crypto different to DNS is OpenNIC. It is a user-run undertaking that provides non-ICANN domains, aiming to decentralize management by neighborhood governance.
