Yes, that's correct. Blockchain-based DNS systems like Namecoin and Blockstack are designed to be independent of traditional DNS and to provide a decentralized alternative. Instead of relying on a centralized authority to manage domain name registrations and resolve domain names to IP addresses, these systems use a distributed network of nodes to maintain a blockchain-based ledger of domain name registrations and associated data. This allows for greater security, privacy, and censorship resistance, as well as the ability to create and manage custom top-level domains.
