Off-Chain Domain Record Resolution Using Blockchain Asset Verification

The patent introduces a blockchain as an intermediary layer between DNS record storage and modification operations. The blockchain stores cryptographic hashes of DNS records and requires cryptographic proof (digital signatures) for any modifications. This intermediary mechanism allows authorized users to modify DNS records while the blockchain verifies the authenticity of modifications through cryptographic validation, thus maintaining both operational flexibility and record integrity.

The patent implements preliminary cryptographic hashing of DNS records before they are stored or modified. The blockchain stores the hash of the DNS record in advance, creating a cryptographic commitment to the original state. Before allowing any modification, the system performs preliminary verification by comparing the hash of the proposed modification against the stored hash, ensuring that only authenticated modifications proceed. This preliminary cryptographic validation prevents malicious modifications while maintaining centralized DNS functionality.

The patent replaces traditional mechanical authorization systems (username/password, access control lists) with cryptographic mechanisms. Instead of relying on centralized authentication servers and complex permission management, the system uses public-key cryptography where users sign modification requests with their private keys. The blockchain network verifies these cryptographic signatures to authorize modifications. This substitution of cryptographic mechanisms for mechanical authorization systems enhances security while actually reducing operational complexity, as cryptographic verification is more reliable and harder to compromise than traditional authorization systems.
