And not accepting the uploading and storing operation of the test data under the condition that the uploading request is not verified. The upload request includes at least a data type, and/or a data format, and/or a logical relationship, a checking mechanism, etc., which are only examples, and there is no specific limitation to the technical feature of the upload request. The storage area may be formed in the blockchain or may be formed as a peripheral storage device, and stores a value derived by an algorithm that can verify integrity and unmodified of the peripheral storage data on the blockchain, which is not limited herein.
Step S120, after the new data is issued a write request by a node, performing a global consensus according to a predetermined logic so that the new data is written into the new block, and enabling each node participating in the consensus to obtain complete block data including the new block data. After the new data is issued a writing request by a node, the block height of the block chain is increased at the moment, the whole network consensus is carried out according to the preset logic so that the new data is written into a new block, each node participating in the consensus acquires the complete block data containing the new block data, and meanwhile, the time when the new data is written and the block height are recorded by means of the timestamp identification of the block chain technology. When the test data is tampered, the tampered test data also carries a timestamp mark, and the block height is changed, so that the authenticity of the data can be verified only by verifying and storing the corresponding timestamp, the block height and other data when the test data is written.
It should be noted that: the time stamping technique is well known in the art of block chaining and is not described in detail herein.
According to the technical scheme of the embodiment, by means of the technical characteristic that the message for storing the test data is notified to all the block chain nodes matched with the storage area, and the timestamp standard and the block height (or called block chain age) carried by the block chain technology are combined, the technical problem that the test data is tampered is solved, and the test data can be safely stored without depending on the credit of a data center or a software service provider.
As a further preferred embodiment, in order to further improve the data security, the above storage method based on test data, wherein, in step S110, an upload request of test data is received, and before the upload request is verified, the method further includes:
step S109, receiving an externally input creation command, and forming the storage area matched with the creation command according to the creation command. The storage area can be realized by an intelligent contract technology, the intelligent contract can specify the data type, the data format and/or the logic relationship at the creation position, and can also specify the participant of the intelligent contract, when the participant of the intelligent contract is any third person, the uploading request of any third person can be verified, after the uploading request is verified, the corresponding data can be uploaded and stored according to the requirement specified by the contract, when the participant of the intelligent contract is a specific person, only the uploading request sent by the specific person can be verified, and after the uploading request is verified, the corresponding data can be uploaded and stored according to the requirement specified by the contract.
As a further preferred embodiment, the above storage method based on test data further comprises:
step S130, receiving an access request, and reading the test data matched with the access request after the access request is verified. The initiator of the access request may be a participant of the intelligent contract or a participant of the non-intelligent contract, and is not limited herein specifically, and the access request may be access to one piece of data, for example, only one piece of test data, or access to a group of pieces of data, for example, a group of test data matching the access request is retrieved through keyword obfuscation, and the test data is summarized and displayed, where the access request is merely an example.
Example two
As described above, when all the test data are stored in the storage area, the storage amount of the test data is relatively large, on one hand, a large storage space is required to implement data storage, and the data uploading speed is slow, and on the other hand, the data reading speed is also relatively slow, based on which, the invention further provides a storage method based on the test data, specifically:

For example, the first memory block is disposed in a core memory space which is high in reading efficiency but relatively less in storing data, and the second memory block is disposed in a peripheral memory space which is relatively low in reading efficiency but relatively higher in storing data.
Step S220, uploading the test data to the second storage block to form storage data matched with the test data;
step S230, encrypting the stored data to form an encrypted link, and forming the new data based on the encrypted link; a node issues a write request to the new data to form a new block recorded with the encryption chain data; the encryption scheme may be formed by a HASH algorithm and the encrypted link may be formed by a HASH pointer chain.
Step S240, performing a global consensus according to a predetermined logic so that each node participating in the consensus acquires complete block data including the new block data. The verification of the new block can be completed by the verification of the existing nodes in the whole network or the verification of the adjacent nodes.
When the verification of the new block data is verified in an existing node verification mode of the whole network, the new block data (which can contain a HASH pointer chain and readable storage data matched with the HASH pointer chain) is sent to each existing node participating in the consensus, each existing node participating in the consensus verifies the new block data (at least whether the verification meets an intelligent contract rule or not) and gives a verification result, and when the verification result is larger than a preset threshold value, the new block data is judged to pass the verification.
When the verification of the new block data is verified in a verification mode of adjacent nodes participating in consensus, the new block data (which can contain a HASH pointer chain and readable storage data matched with the HASH pointer chain) is sent to the adjacent nodes participating in consensus, the adjacent nodes participating in consensus verify the new block data (at least verify whether the new block data meets the intelligent contract rule) and give a verification result, and when the verification result is true, the new block data is judged to be verified to be passed.
In the above embodiment, the data is stored in a chain manner, so that the data uploading speed and the reading efficiency are improved, and the data storage cost is reduced.
It should be noted that: the first embodiment and the second embodiment can be combined for use, and the specific combination mode is as follows: first, a data storage threshold is set (the data storage threshold is set by a user or an intelligent contract creator, which is not specifically limited here), an upload request of test data is received, a data amount of the test data is scanned according to the upload request, a scanning result matched with the test data is obtained, the storage method of the first embodiment is executed in a state where the scanning result is smaller than the data storage threshold, and the storage method of the second embodiment is executed in a state where the scanning result is greater than the data storage threshold.
In addition, after all the data are stored, the uploading interface is closed, all the data are subjected to signature encryption processing, and a HASH pointer chain can be formed again for storage.
In another aspect, the present invention further provides a computer-readable storage medium, on which a computer program is stored, wherein the computer program, when executed by a processor, implements any of the above-mentioned experimental data-based storage methods.
