DNS system based on block chain technology

Abstract

According to the DNS system based on the block chain technology, a main chain is adopted to record a small amount of important information and is mainly responsible for storing requests on a top-leveldomain and Hash values of sub-chains; wherein the plurality of sub-chains are respectively connected with the main chain, can be expanded, migrated and properly discarded, and are mainly responsiblefor storing all operation requests under a specific TLD, different sub-chains store records under different TLDs, and all the sub-chains and the main chain maintain the same block height; the nodes are distributed on the main chain and the sub-chains and allow only the main chain and part of the sub-chains to be stored; anonymity of voting process alliance nodes is ensured by utilizing a linkablering signature technology; the node processes the operation on the sub-chain which is not stored by using the proxy signature, the throughput of the system is improved by using the fragmentation technology, the technical problems of poor security, limited performance, poor expansibility and low throughput in the prior art are solved, and the technical effects of higher security, higher expandability, higher throughput and better anonymity are achieved.

Description

technical field [0001] The present invention relates to the Internet field, in particular, to a DNS system based on block chain technology. Background technique [0002] Such as figure 1 As shown, Domain Name System DNS is an important infrastructure on the Internet. Domain names are easy for people to understand and use, while IP addresses are more conducive to computer processing. DNS is responsible for converting domain names into IP addresses, making it easier for people to access the Internet. The current DNS is a centralized distributed structure, which is uniformly scheduled and managed by ICANN. As a centralized organization, ICANN completely controls the distribution of domain names, which has serious risks of power abuse and single-point failure. In addition, the current DNS is vulnerable to various problems such as DDOS attacks, cache pollution attacks, disappearance risks, and blinding risks. According to the "Global DNS Threat Report 2018", at least 77% of org...

Problems solved by technology

[0009] The present invention provides a DNS system based on block chain technology, adopts a main chain, records a small amount of important information, and is mainly responsible for storing requests on top-level domains and hash values ​​of sub-chains; multiple sub-chains respectively connected to the main chain Chain, which can be extended, migrated and discarded appropriately, is mainly responsible for storing all operation requests under a specific TLD, different sub-chains store records under different TLDs, and all sub-chains maintain the same block height as the main chain ; Nodes, including alliance nodes and ordinary nodes, are distributed on the main chain and the sub-chains and only store part of the sub-chains, and use proxy signatures to allow nodes to process operations on those sub-chains that are not stored; the alliance nodes , distributed on the main chain, can manage the rights of requests on the TLD; the ordinary nodes, distributed on the sub-chain, can participate in various operation requests under the TLD, solving the problem of poor security in the prior art, Technical problems of limited performance, poor scalability, and low throughput
