SECURE AND TRANSPARENT DNS RESOLUTION USING BLOCKCHAIN TECHNOLOGY

  • Abstract:
  • The Domain Name System (DNS) remains vulnerable to attacks such as spoofing, cache poisoning, and unauthorized record manipulation due to its centralized and insecure design. This paper presents a blockchain-based framework for secure and transparent DNS resolution using Python and Flask technologies. Each domain-to-IP mapping is stored as an immutable block containing a hash, timestamp, and previous link, ensuring data integrity and tamper resistance. A lightweight blockchain ledger integrated with a custom DNS resolver and a web-based interface enables real-time verification and record management. Experimental results demonstrate reliable query performance with minimal latency, enhanced security, and full transparency in DNS operations, thereby improving trust and resilience across networked systems [1], [2].
