Embodiment 1
[0043] see figure 1 , a method for storing images and texts, comprising the steps of:
[0044] Step 102, store the block chain by a common architecture of several storage nodes;
[0045] Step 104, establishing a rejection record database at each storage node;
[0046] Step 106, the real-name user initiates a graphic information broadcast application to any storage node;
[0047] Step 108, comparing the broadcast application information with the rejection records of the rejection record database one by one, if the same application record is found, the broadcast application is directly rejected, and if the same application record is not found, then the next step is performed;
[0048] Step 110, comparing the graphic information to be broadcast with the graphic information in the storage node database according to specific conditions, and broadcasting the graphic information to be broadcast to the storage block chain if the conditions are not met , if the conditions are met, t...
Embodiment 2
[0071] A block chain-based image and text storage system of the present invention is characterized in that it includes:
[0072] at least one processor;
[0073] at least one memory for storing at least one program;
[0074] When the at least one program is executed by the at least one processor, the at least one processor implements the aforementioned image-text storage method.
[0075] With this technical solution, the above-mentioned process is realized through the execution of computer programs, and the execution efficiency of storing graphic information into the chain is guaranteed.
[0076] In summary, compared with the prior art, the beneficial effects of the present invention are:
[0077] Reject the same or similar applications, avoid repeated storage, save storage space, further optimize the storage content, avoid meaningless comparison work, improve the processing efficiency of storage applications, and pass storage by the storage node The set keyword index is us...

Abstract
The invention discloses an image-text storage method and system based on a block chain. The method includes: establishing a rejection recorddatabase at a storage node of the block chain, and screening the graphic and text information broadcast applications in a secondary comparison mode; broadcasting the screened graphic and text information which does not conform to the specific condition to a block chain for storage, and rejecting the broadcast application which is compared and screened to conform to the specific condition, and broadcasting the application record to a rejection recorddatabase of each node. By adopting the method, not only is the storage space saved, but also the content of the stored graphic and text information is optimized, and the efficiency of storage application review is greatly improved.
Description
technical field [0001] The invention relates to the technical field of block chains, in particular to a method and system for storing images and texts based on block chains. Background technique [0002] Blockchain technology is a distributed ledger technology that has emerged in recent years. It is a collection of computer information technology applications such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. It is characterized by decentralization, openness and transparency, unchangeable, and unforgeable . According to the security characteristics of the blockchain, no one can obtain permission to tamper with the data stored in the blockchain, nor can it be deleted or forged, which makes the blockchain an ideal, safe, The storage technology of public data, for some key data that does not need to be changed or is not allowed to be changed, blockchain provides an ideal data storage implementation method. [0003] H...
