It should be noted that different items correspond to different certificates, a certificate is Token, which is one of important components in the block chain financial technology, Token may represent any valuable things, including but not limited to tokens, real estate, equity, bond, copyright and patent right, Token may be regarded as a platform equity, may have dividend to obtain income, and Token may also be purchased by related users; the evidence-passing management equipment comprises a contract node, a verification node, a common identification node and a user node, wherein the contract node is used for receiving data obtained by the evidence-passing management equipment and determining whether to release target evidence-passing according to the data, the contract node runs completely and autonomously and can run without being interfered by a third party when receiving the data, the verification node is used for ensuring fund security of users, the common identification node is used for storing common identification parameters of all users participating in public recruitment or purchase, the user node is used for logging in an account number of the user, and the user can purchase the target evidence-passing through the user node, monitor projects corresponding to the target evidence-passing and the like; the information in the contract node, the verification node, the consensus node and the user node may be communicated with each other.
In the block chain-based evidence-passing management method of this embodiment, a time point price set of a target evidence-passing in a statistical period is obtained, and each time point price in the time point price set is compared with a public recruitment price of the target evidence-passing to obtain a comparison result; and if the comparison result is that the time point prices which are greater than the public recruitment price in the time point price set are not less than a first preset proportion and the time point prices are all greater than a preset value, calling contract nodes in the block chain to release the target general evidence. According to the method, the comparison result is obtained, the preset time point price of each time point price in the time point price set is greater than the public recruitment price, the target general evidence is released only when the time point price of each time point price in the time point price set is not less than the first preset proportion and the time point prices are all greater than the preset values, and therefore the arbitrage situation is prevented, and the price of the target general evidence is not broken after the public recruitment.
The respective steps will be described in detail below:
step S10, acquiring a time point price set of the target general evidence in a statistical period, and comparing each time point price in the time point price set with the public recruitment price of the target general evidence to obtain a comparison result;
in this embodiment, the evidence collection management device acquires a time point price set of the target evidence collection according to the statistical period, and compares each time point price in the time point price set with a public recruitment price of the target evidence collection to obtain a comparison result; such as: the evidence collection management device determines a statistical period to be once per hour after the public recruitment is finished, monitors the time point price of the target evidence collection after the public recruitment in real time, obtains a time point price set by counting per hour after the public recruitment is finished according to the statistical period, and compares each time point price in the time point price set with the public recruitment price of the target evidence collection to obtain a comparison result; it should be noted that, related users participating in the public recruitment issue related consensus parameters at corresponding user nodes, and the evidence-based management device calls contract nodes to acquire the consensus parameters to determine a statistical period; the statistical period can be 1 hour, 1 day, 1 week, etc.; the target general-purpose public price is generally set to 1 unit by default for convenient calculation; the spot price is typically updated once every minute.
Specifically, step S10 is followed by:
step a, if the comparison result shows that the time point price which is greater than the public recruitment price in the time point price set is smaller than the first preset proportion, or the time point price is not greater than the preset value, executing the steps of: and acquiring a time point price set of the target pass certificate in the statistical period.
In the step, if the comparison result obtained by the evidence-passing management device is that the time point price which is greater than the public recruitment price in the time point price set is smaller than a first preset proportion or the time point price is not greater than a preset value, the time point price set of the target evidence-passing in the statistical period is continuously obtained; such as: and the evidence collection management equipment determines that the common price of the target evidence collection is 1 unit, compares each time point price in the time point price set with the common price of the target evidence collection respectively to obtain a comparison result, namely the time point price which is larger than the common price in the time point price set is smaller than a first preset proportion or the time point price is not larger than a preset value, and then continuously acquires the time point price set of the target evidence collection in the statistical period. It should be noted that the time point price which is greater than the public recruitment price in the time point price set is smaller than the first preset proportion, and the time point price is not greater than the preset value, one or both of the two conditions are satisfied, the evidence obtaining management device does not release the target evidence obtaining, and the time point price set of the target evidence obtaining in the statistical period is continuously obtained.
Step S20, if the comparison result indicates that the time point prices in the time point price set that are greater than the public recruitment price are not less than a first preset proportion, and the time point prices are all greater than a preset value, invoking contract nodes in the block chain to release the target evidence.
In this embodiment, the evidence obtaining result of the evidence obtaining management device is that the time point prices in the time point price set which are greater than the public recruitment price are not less than the first preset proportion, and the time point prices are all greater than the preset value, and then the contract node in the calling block chain releases the target evidence. It should be noted that the first preset proportion refers to a proportion of the time point price sticky time point price set which is greater than the public recruitment price, and optionally, the first preset proportion may be 70%, 80%, and the like, and is determined by related research and development personnel; the preset value is set by related research and development personnel, optionally, the preset value can be a fixed value, and the preset value can also be a preset multiple, wherein the preset multiple is a multiple of the public recruitment price of the target general evidence, and the multiple can be an integral multiple, such as 2 times, 3 times and the like, or a non-integral multiple, such as 2.4 times, 3.6 times and the like; the contract node stores preset conversion contracts set by related research and development personnel, the management rules of the target certificates can release corresponding amount of target certificates according to the comparison result, and a user can know the preset conversion contracts on the contract node through a user node.
Specifically, step S20 further includes:
step b, calling contract nodes in the block chain, converting the preset values into second preset proportions according to preset conversion contracts, and multiplying the second preset proportions by the total number of the target certificates to obtain the release number;
in the step, the certification passing management equipment calls contract nodes in the block chain, changes the preset values into corresponding second preset proportions according to preset conversion contracts, and multiplies the second preset proportions by the total number of the target certification passing to obtain the release number; such as: when the total number of the target certificates is 1000 and the preset value is 2 times of the public price, the certificate-passing management device calls contract nodes in the block chain, converts the preset multiple of 2 times into a second preset proportion of 20% according to a preset conversion contract in the contract nodes, and multiplies the total number of the target certificates with the total number of the target certificates being 1000 to obtain the release number of 200. It should be noted that the preset conversion contract is set by the relevant researcher and is stored in advance on the contract node, and the specific content of the preset conversion contract is as follows: optionally, after the public offering is finished, 10% of the total number of the target general symptoms are released, the time point prices of the target general symptoms in the statistical period are counted, and compared with the public offering price, 10% is released every 1 time, and so on, optionally, in the time point price set of the target general symptoms in the statistical period, the time point price which is greater than the public offering price in the time point price set is greater than a first preset proportion, and the time point price is greater than a preset value, the target general symptoms of the release quantity corresponding to the preset value are released, and the release quantities corresponding to different preset values are different, for example, the preset value is 1.5 times of the public offering price, and the corresponding release quantity is 15% of the total number of the target general symptoms.
Step c, according to the release quantity, executing the steps of: and calling a contract node in the block chain to release the target pass certificate.
In the step, the certification passing management equipment calls contract nodes in the block chain to release the target certification according to the release quantity; such as: the evidence-passing management equipment obtains the release quantity of 200, and calls the contract node, and because the contract node releases the target evidence-passing quantity of 100 and stores the release record in the contract node when the public recruitment is finished, the requirement of the release quantity of 200 can be met only by releasing the target evidence-passing quantity of 100; if the preset proportion is 30%, the release quantity is 300, and the requirement that the release quantity is 300 can be met only by releasing the target certificate with the quantity of 200; if the number of the target certificates is 200, when the preset proportion is 30%, only the target certificates with the number of 100 need to be released again, so that the requirement that the number of the released target certificates is 300 can be met, and other conditions are similar to the above conditions and are not described one by one; it should be noted that, when the recruitment is completed, the release node may release 10% of the total number of target certificates.
Further, the step after releasing the target pass further comprises:
and sending the released preset number of target certificates to the block chain for users corresponding to the user nodes in the block chain to purchase, and updating the number of the purchased target certificates in the corresponding user nodes according to the user purchasing condition.
In the step, the corresponding certificate management device sends the released preset number of target certificates to the block chain, the related users can purchase the released target certificates, and after the related users purchase the target certificates, the corresponding certificate management device corresponds to the number of the purchased target certificates in the user node in a root mode; such as: the same-evidence management equipment releases the target evidence with the quantity of 100, and sends the 100 target evidence to all user nodes, related users log in to the corresponding user nodes through terminal equipment to purchase the target evidence, if a certain user purchases 10 target evidence when being recruited, when the target evidence is released, 20 target evidence are purchased again, and the evidence management equipment updates the quantity of the purchased target evidence on the corresponding user nodes according to account information and purchase records of the user.
And if the contract node is detected to release all the target certificates, closing the contract node.
In the step, after detecting that all target certificates are released by the contract node, the certificate authority device closes the contract node; it should be noted that, if the certification authority detects that a new project is issued, the contract node is restarted to manage the certification in the new project.
In the block chain-based evidence-passing management method of this embodiment, a time point price set of a target evidence-passing in a statistical period is obtained, and each time point price in the time point price set is compared with a public recruitment price of the target evidence-passing to obtain a comparison result; if the evidence-based target evidence collection management equipment obtains a comparison result that the time point prices which are greater than the public price in the time point price set are not smaller than a first preset proportion and the time point prices are all greater than a preset value, calling contract nodes in the block chain, converting the preset value into a corresponding release quantity according to a preset conversion contract, calling the contract nodes according to the release quantity, and releasing the target evidence of the preset quantity; and if the evidence-passing management equipment obtains the comparison result that the price of the time point which is greater than the public recruitment price in the time point price set is smaller than a first preset proportion or the price of the time point is not greater than the preset value, continuously acquiring the price set of the target evidence-passing in the statistical period. By managing the release of the target general evidence, when the time point prices which are greater than the public recruitment price in the time point price set are not less than a first preset proportion and the time point prices are all greater than a preset value, the target general evidence is released, the arbitrage situation is prevented, and the price of the target general evidence is not broken after the public recruitment.
Further, based on the first embodiment of the block chain-based certification management method of the present invention, a second embodiment of the block chain-based certification management method of the present invention is proposed.
The second embodiment of the block chain-based certification management method is different from the first embodiment of the block chain-based certification management method in that the step S10 is preceded by a step further including:
