Problems solved by technology

[0002] In the Internet information age, there are a lot of information flows and the mixture of true and false information. A lot of wrong and false information makes it difficult for users to identify valid, true and available information. A relatively common scenario is various real estate information networks. There may be multiple intermediaries publishing a house. , and the information released by each intermediary is not the same, so it is difficult for users to distinguish which is the real information

Embodiment Construction

[0033] Blockchain technology, also known as distributed ledger technology, is an emerging technology in which several computing devices jointly participate in "bookkeeping" and jointly maintain a complete distributed database. Due to the characteristics of decentralization, openness and transparency of blockchain technology, each computing device can participate in database records, and data synchronization between computing devices can be performed quickly, blockchain technology has been widely used in many fields. to apply.

[0034] In order to overcome the problem that the same data information is released by multiple parties and it is difficult to distinguish between true and false in the existing Internet, this specification provides a blockchain-based data storage method. like figure 1 As shown, the embodiments provided in this specification illustrate a blockchain-based data storage method, including:

[0035] Step 102: Receive a candidate block proposed by the target...

Abstract

One or more embodiments of the present specification provides or provide a block chain based data storage method and apparatus. The method includes receiving a candidate block proposed by a target node, a block header of the candidate block including metadata of target data, and a block body of the candidate block including content of the target data. Initiating consensus processing on the candidate blocks; In response to the consensus result passed by the candidate block consensus process, the candidate block is stored as a newest block in a distributed database of the block chain to completedata storage of the target data.

Description

technical field [0001] This specification relates to the field of network communication technologies, and in particular, to a method and device for data storage based on blockchain. Background technique [0002] In the age of Internet information, there are a lot of information flows and the true and false are mixed. Many false and false information make it difficult for users to identify valid and available information. A relatively common scenario is various real estate information networks. A property may be published by multiple intermediaries. , and the information released by each intermediary is not the same, so it is difficult for users to distinguish which is the real information. SUMMARY OF THE INVENTION [0003] In response to the problems raised above, this specification provides a blockchain-based data storage method, including: [0004] Receive a candidate block proposed by the target node, the block header of the candidate block includes the metadata of the...
