Problems solved by technology

In order to achieve cross-chain and real-time retrieval of data on different chains, there are problems. It is necessary to develop corresponding services for different blockchains and expose them. Business application systems such as DAPP call services of different chains to obtain data. Parse and load separately, the operation is complicated, the processing efficiency is low, and the development is difficult

Embodiment 1

[0032] refer to figure 1 ,Such as figure 1 As shown, a blockchain-based cross-chain data retrieval system includes:

[0033] Registration module: register candidate nodes of different blockchains, synchronize blockchain data in real time, and synchronize blockchain data to different message queues in real time;

[0034] Analysis module: analyze the data in different message queues, desensitize the data, and save the desensitized data to the search engine;

[0035] Search module: retrieve cross-chain data from search engines to realize cross-chain retrieval of blockchain data;

[0036] The registration module joins different blockchain networks. Only by registering as the corresponding candidate node can a complete data backup be obtained. After obtaining a complete data backup, it is impossible to process a large amount of data in real time, so the data is synchronized to different message queues for decoupling analysis module; the parsing module parses the data of differen...

Embodiment 2

[0038] refer to figure 2 ,Such as figure 2 As shown, a blockchain-based cross-chain data retrieval method includes the following steps:

[0039] S1, the registration module registers candidate nodes of different blockchains, synchronizes blockchain data in real time, and

[0040] Blockchain data is synchronized to different message queues in real time;

[0041] S2, the parsing module parses the data in different message queues, desensitizes the data, and saves the desensitized data into the search engine;

[0042] S3, the search module retrieves cross-chain data from the search engine to realize cross-chain retrieval of blockchain data.

[0043] The step S1 is specifically: the registration module registers candidate nodes of different blockchains, including updating source code, compiling, installing, and registering through commands, such as the EOS node registration command: cleos --wallet-url http: / / 127.0.0.1 :8900 --url http: / / 192.168.154.157:8888 system regproducer...

Abstract

The invention discloses a cross-link data retrieval system and a cross-link data retrieval method based on a block chain. The cross-link data retrieval system based on the block chain comprises a registration module, which registers nodes selected from different block chains, synchronizes the block chain data in real time, and synchronizes the block chain data to different message queues in real time; a parsing module: parsing the data in different message queues, desensitizing the data, and saving the desensitized data to the search engine; a search module: retrieve the cross-link data from the search engine, and realize the cross-link retrieval of the block chain data. The invention relates to a cross-link data retrieval system and method, which aims at solving the background technical problem of how to break through different block chains so as to realize data intercommunication.

Description

technical field [0001] The present invention relates to block chains, in particular to a cross-chain data retrieval system based on block chains. Background technique [0002] At present, the application of blockchain is the trend of Internet development. Many countries are trying to apply blockchain technology to various social fields, but so far, no country has figured out what the real blockchain is. [0003] Generally speaking, "nodes" refer to computers in the blockchain network, including mobile phones, mining machines, desktops, servers, and so on. People who operate a node can be ordinary wallet users, miners, and multiple people. For example, the Bitcoin network belongs to the public chain. When we run the bitcoind program on our computer connected to the Internet, the computer becomes a node in the Bitcoin network. [0004] For a public chain like Bitcoin, in theory, downloading the complete blockchain, participating in transactions and mining is considered a nod...
