Embodiment 1
[0026] refer to figure 1 ,Such as figure 1 As shown, a fast data retrieval system based on blockchain, including:
[0027] Registration module: Register blockchain candidate nodes, synchronize blockchain data in real time, and synchronize blockchain data to the pending message queue in real time;
[0028] Data index module: read the message queue data to be processed in real time, desensitize the data, and index the desensitized data;
[0029] Retrieval module: quickly retrieve the blockchain data according to the index, and obtain the data transaction number, and obtain the actual data from the blockchain according to the transaction number and return it;
[0030] 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. The data can only be synchronized to different messag...
Embodiment 2
[0032] refer to figure 2 ,Such as figure 2 As shown, a fast data retrieval method based on blockchain includes the following steps:
[0033] S1, the registration module, registers the blockchain candidate nodes, synchronizes the blockchain data in real time, and synchronizes the blockchain data to the pending message queue in real time;
[0034] S2, the data index module reads the message queue data to be processed in real time, desensitizes the data, and builds an index for the desensitized data;
[0035] S3, the retrieval module quickly retrieves the blockchain data according to the index, and obtains the data transaction number, and obtains the actual data from the blockchain according to the transaction number and returns it.
[0036] The step S1 is specifically: the registration module registers the blockchain candidate node, updates the source code, compiles, installs, and registers through commands, such as the EOS node registration command: cleos --wallet-url http:...
