Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a block chain-based data cycle writing method and system, which can effectively control the volume of the block chain database, and the data that meets the preset trigger conditions will no longer be displayed in the area. In the block chain system, it is overwritten and destroyed by new data, and the privacy and confidentiality are better. At the same time, because multiple block chains are used as backups to store data, it can be guaranteed that all block chains will not be invalid due to a block chain failure. The situation that the data to be stored cannot be stored in time occurs, and the continuity and security of data storage are better

Embodiment 1

[0055] Embodiment 1. A blockchain-based data loop writing method. Combine below figure 1 The method provided in this embodiment will be described in detail.

[0056] see figure 1 , S101. Before writing a new data block into the data block chain, determine whether a preset trigger condition for cyclic writing is satisfied.

[0057] Specifically, before writing new data in the blockchain data, it is judged whether the original data in the blockchain database meets the preset trigger conditions, wherein the trigger conditions specifically include time trigger conditions, Storage capacity trigger conditions or specific event trigger conditions.

[0058] S102. If the cyclic write condition is satisfied, the new data block written in the data block chain will overwrite the original data block; otherwise, the new data block will be written directly without overwriting the original data block .

[0059] Specifically, if the original data in the blockchain database satisfies the p...

Embodiment 2

[0074] Embodiment 2. A blockchain-based data circulation writing system. Combine below figure 2 The system provided in this embodiment will be described in detail.

[0075] see figure 2 The system provided in this embodiment includes a judging unit, a data writing unit, a Hash writing unit, a download verification unit, a data backup unit, a calculation verification unit, a Hash backup unit and a verification unit.

[0076] The judging unit is configured to judge whether a preset trigger condition for cyclic writing is met before writing a new data block into the data block chain.

[0077] The data writing unit is used to cover the original data block with the new data block written in the data block chain if the cyclic write condition is satisfied, otherwise the new data block is written directly, and the original data block is not corrected. The data blocks are overwritten.

[0078] The Hash writing unit is used for writing the hash value generated by the new data bloc...

Abstract

The invention discloses a cyclic writing method and system of data on the basis of a block chain. Before new data is written into the block chain, whether data stored in a block chain database meets a preset trigger condition or not is judged, the new data is written to cover and destroy original data under a situation that a preset condition is met, and usefulness data can be destroyed while the volume of the block chain is effectively controlled. The data is stored into the block chain database to guarantee that data is not tampered and can be safely stored, in addition, a cyclic writing way is adopted to effectively control the volume of the block chain database, the data which meets the preset trigger condition is not displayed in a block chain system and is covered and destroyed by the new data, privacy and privacy are good, the storage of a hash value corresponding to a data block also can guarantee to verify whether the downloaded data is correct or not, and the cyclic writing method and system is safe, convenient and high in practicality.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a block chain-based data cycle writing method and system. Background technique [0002] The existing blockchain systems are all chained blockchains, and all data written are permanently stored in the database. Everyone with network access rights can unconditionally access and download these permanent data. There are two problems in this permanently reserved chained blockchain system: 1. As time goes by, more and more data needs to be stored, and the block database will become larger and larger, which is inconvenient to save, but it is not All data needs to be stored permanently, and some data only need to be kept within the corresponding number of years, and the data beyond the number of years can be deleted; 2. Some confidential files or personal private information stored also have a certain storage time limit, reaching a certain time limit Finally, it needs to be de...
