Abstract
In the current Internet era, whether the domain name system (DNS) can achieve efficient resolution is of great significance for optimizing user experience and promoting global development. However, the existing DNS architectures have flaws in dealing with network service latency and ensuring their own robustness. Based on this, this study constructs a blockchain-based distributed domain master architecture, aiming to optimize the resolution effect of top-level domains (TLDs). As internet service latency continues to pose severe challenges to user experience and global development, the demand for accelerated DNS resolution always exists. Although local caching has always been helpful in improving DNS efficiency, how to ensure the integrity of cached records is a tricky problem. The new architecture proposed in this study adopts a consortium blockchain framework, allowing nodes to freely enter and exit. Consensus is reached through the 3R-PBFT algorithm, strengthening system security. Focusing on the top-level domains of.com and.net, an in-depth exploration is conducted on the effect of locally deployed caches on resolution time, highlighting the key value of TLD caches in enhancing the DNS resolution speed. Experimental results show that the local cache implemented through the consortium blockchain architecture can not only improve the security of the cache but also reduce the latency of DNS resolution.
