In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following describes specific technical solutions of the present invention in further detail with reference to the accompanying drawings in the embodiments of the present invention. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.
Before further detailed description of the embodiments of the present application, terms and expressions referred to in the embodiments of the present application will be described, and the terms and expressions referred to in the embodiments of the present application will be used for the following explanation.
1) A Block chain (Blockchain) is a storage structure for encrypted, chained transactions formed from blocks (blocks). The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The block chain is essentially a decentralized database, and is used as the bottom technology of the bitcoin, and is a series of data blocks which are generated by correlation through a cryptographic method, wherein each data block contains information of a batch of bitcoin network transactions, and the information is used for verifying the validity (anti-counterfeiting) of the information and generating the next block.
For example, the header of each block may include hash values of all transactions in the block, and also include hash values of all transactions in the previous block, so as to achieve tamper resistance and forgery resistance of the transactions in the block based on the hash values; newly generated transactions, after being filled into the tiles and passing through the consensus of nodes in the blockchain network, are appended to the end of the blockchain to form a chain growth.
2) A Blockchain Network (Blockchain Network) incorporates new blocks into a set of nodes of a Blockchain in a consensus manner.
3) Smart Contracts (Smart Contracts), also known as chain codes (chainodes) or application codes, are a computer protocol intended to propagate, verify or execute Contracts in an informative manner. Smart contracts allow trusted transactions to be conducted without third parties, which transactions are traceable and irreversible.
The intelligent contract is deployed in a program in a node of the block chain network, and the node executes the intelligent contract called in the received transaction to update or inquire the key value of the state database for data.
The intelligent contract can be automatically triggered to execute when the constraint condition is met, manual intervention is not needed, and the intelligent contract can also be automatically contracted when the condition is not met, and theoretically, all terms agreed in advance can be triggered to execute. The smart contracts encapsulate the relevant processes that interact directly with the block ledger, for example being invoked by an application, performing functions including initiating transactions and querying transactions.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

In addition, the nodes in the block chain network illustrated in fig. 2 may be functionally hierarchical, for example, some nodes have high reputation and some nodes have low reputation, and the roles of some nodes may have been determined at the beginning of building the block chain network, and these nodes have specific functions assigned to them, for example, in a building block chain-based alumni economic system, the node corresponding to the role of the alumni has an identity authentication function, that is, when all nodes join the alumni economic system based on the block chain, the node is required to perform identity authentication on the node. It should be understood that the nodes in the blockchain network also have other functions that the blockchain network should have, and thus are not described in detail herein. The blockchain management platform 220 may be used for authentication authorization when a node accesses the blockchain network 200, broadcasting information issued by the node, and the like. The execution subject of the block chain-based evidence obtaining method provided by the embodiment of the present invention may be the block chain management platform 220.
Here, the credential extraction request may be request information that is sent by the first node to the blockchain management platform 220 and includes at least an item number in order to extract a certain number of blockchain credentials. The item number may refer to a number set by the blockchain management platform to distinguish a plurality of items simultaneously published on the blockchain network. It should be understood that the form of the item number may be various, and in any case, the item number may be a pure number, or a mixture of numbers and english letters, for example, and the present invention is not limited to the specific form. It should be understood that the project may refer to any project that can operate, such as an infrastructure project of a 5G network, a production project of a 5G handset, and the like.
S102: judging whether the item corresponding to the item number is in a locked state; and determining whether the first node is allowed to extract the block link permit or not according to the judgment result.
It should be noted that, here, it may be determined that the item corresponding to the item number is not in the locked state according to the intelligent contract in the blockchain network, and then, according to this determination result, it is determined whether to allow the first node to extract the blockchain pass certificate. Wherein the locked state, as the name implies, in which the accumulated blockchain is unveiled from being used.
In some embodiments, the determining whether the item corresponding to the item number is in the locked state includes:
acquiring the time to be extracted in the certificate passing extraction request;
judging whether the time to be extracted is within a locking time limit or not;
when the time to be extracted is judged not to be in the locking period, judging that the item corresponding to the item number is not in a locking state;
when the time to be extracted is judged to be within the locking period, judging that the item corresponding to the item number is in the locking state;

It should be noted that the accumulated blockchains may be set manually so as to be in a locked state under what condition. Here, as an example only, two determination methods are proposed: the first method comprises the following steps: judging whether the time to be extracted is within a specified locking period; and the second method comprises the following steps: by judging whether the accumulated distributable block chain general evidence reaches the appointed number. Wherein, the time to be extracted can be an accurate time point, such as 5/21/2021, 12 points; or a time period, for example, the time to be extracted may be any time in the day of 2021 year, 5 month and 21 days. The locking term may be a set period of time, for example, the locking term may be a period of time from the start of the item corresponding to the item number to the arrival at an appointed time point. The appointed time can be set manually according to the requirements of the user.

The reminding information can be any words, pictures, symbols, videos and the like which can indicate the extraction quantity of the user modification block link certificate corresponding to the first node. That is, the reminder indicates to the user the direction of the modification. The set number may be set by a node having modification authority. The first specific amount and the second specific amount may be equal or different, and are only for convenience of description and do not limit the present invention.
