A blockchain-based domain is a digital address managed on a decentralized network. Unlike traditional domains, which depend on centralized registrars, these domains use blockchain technology to ensure ownership and control.Owners of blockchain-based domains can transfer or sell their domains securely without intermediaries. Transactions are recorded on the blockchain, providing transparency and immutability. This means that once a domain is registered to a user, it cannot be altered or taken away by a third party.Moreover, blockchain-based domains often come with enhanced privacy and security features. Users have full ownership, typically managed through a private key. This decentralized approach reduces the risks of hacking and fraud commonly associated with centralized systems.These domains can also enable new functionalities, such as integrating smart contracts or serving as decentralized identifiers. Overall, they represent a shift toward user-centric control in the online address system.
