Detailed Description
In order to make the objects, technical solutions and advantages of the present disclosure more apparent, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step based on the embodiments in the description belong to the protection scope of the present application.
The embodiment of the application provides a method and a scheme for storing data based on a block chain, the improvement is carried out on the basis of not violating the basic idea of the block chain by defining a core block chain, each node has the option of data in the block chain while enjoying the supervision right and the voting right, the option of the core block chain is greatly reduced, the storage cost of the node is greatly reduced, and the reality and the reliability of the data are guaranteed.
The block chain is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence, and is a distributed account book which is guaranteed in a cryptographic mode and cannot be tampered and forged.
In a blockchain, the hash value of each block is attached to the hash value of the previous block, each hash value is unique, and once changed, the blocks downstream of the block are changed. In the prior art, a node usually stores all data from a created block to the present, and this retention mode retains all characteristics of a block chain, but wastes storage space, increases the hardware requirement for storing data, and increases the running cost of the block chain.
The storage mode of the block chain is improved based on the problem. In the node, the latest block or a block at a certain position is defined as a new created block, and information of all blocks before the block is deleted after confirming that the information of the block is completely consistent with information of one core block chain. And then downloaded back from the core block chain when it is desired to retrieve the piece of deleted tile information.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a method provided in an embodiment of the present disclosure. As shown in fig. 1. The method comprises the following steps:
s101, a core block chain is obtained, and partial or all writing chain information is stored in the core block chain;
s102, determining a first block chain positioned in front of a first block through the first block in the block chain;
s103, judging whether the core block chain contains the first block chain or not, if so, deleting the first block chain, and taking the first block as a new created block.
The block chain is composed of a plurality of connected blocks, each block records the transaction condition of bitcoin in the network for a period of time, and the blocks can be regarded as account pages in the account book. The first block to be constructed earliest is called the founder block and has a unique id (identity document) identification number. Each subsequently created block, except the created block, contains two ID numbers, one being the ID number of the block itself and the other being the ID number of the preamble block. All blocks are connected in sequence through the front-back pointing relationship between ID numbers to form a block chain.
According to the specific embodiment of the present invention, the core block chain refers to a block chain storing part or all of the write chain information, and it should be noted that there should be a plurality of core block chains storing all of the write chain information; there may be a plurality of core block chains storing partial write chain information. Multiple types of core block chains exist simultaneously.
Preferably, in one node, the information may be acquired from a plurality of core block chains, respectively, and if there is no information required in the first core block chain or the information is in doubt, the second core block chain may be acquired and the information in the second core block chain may be downloaded.
According to the embodiment of the present invention, when a node is newly added to a block chain, it is determined whether a core block chain is stored in the node, if the core block chain is not stored, a second block newly formed at the moment of the block chain may be used as an created block in the node, and when the node wants previous block chain information, the second block may be downloaded at any time.
According to an embodiment of the present invention, after step S103, the method further includes: and downloading part or all of the first block chain through the core block chain, and redefining a new created block.
According to the embodiment of the present invention, in the block chain, no matter how much the stored write chain information exists, the supervision right of the node exists from the beginning, and each node can supervise the block information in the core block chain in real time, and if the block information of the core block chain changes, the change condition of the block information is broadcasted to inform each node in the block chain.
Suitably, each new block written into the chain of core blocks is also subject to supervision by the remaining nodes, in particular, a third block in the chain of core blocks, which is a block that is susceptible to being formed at the current time of transaction; and judging and forming the transaction specification in the third block, and broadcasting to inform nodes in a block chain.
According to the embodiment of the invention, each node has a voting right, and when the block information in the core block chain is determined to be changed, each node uses the voting right to determine whether to change the information in the core block chain according to a consensus mechanism in the block chain.
The above embodiments may be implemented by smart contracts, or may be implemented by other ways, and the present invention is not limited to this. The intelligent contract is an automatically running script which is deployed on a blockchain, and has the characteristic of being transparent in public because the intelligent contract is arranged on the blockchain. A user presets rules through an intelligent contract so as to write data into a block chain and acquire data browsing permission, and disclosure of privacy information is avoided to a great extent. Of course, the smart contracts are not the only implementation manner of the present application, and are set correspondingly according to different blockchain platforms, such as an ethernet house, a super book, and the like.
Generally, core block chains have high requirements on hardware and environment, and therefore, mechanisms that are conditional and have high public confidence may be selected according to embodiments of the present invention. Such as government agencies, notary agencies, or large well-credited businesses.
