For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
First realityExamples
Referring to fig. 1, a flow chart of a blockchain-based number shaking method is provided in this embodiment, and the method includes the following steps:
s101: and receiving a first shake-number data uplink request sent by the shake-number sponsor, wherein the first shake-number data uplink request is uplink after passing the certification of the notarization institution.
In the embodiment, in order to realize the full-flow hasping of lottery numbers, the lottery numbers are more fair, fair and public. The public trust and influence of various shaking activities are assisted, the problems of cheating and the like of shaking are solved, and a shaking sponsor, a shaking participant and a notarization mechanism are simultaneously connected to establish a alliance chain, so that the shaking sponsor, the shaking participant and the notarization mechanism are all block chain nodes on the alliance chain.
Moreover, it should be noted that each node (such as the sponsor of the shake number and the notarization organization) on the federation chain needs to pass qualification verification at the national notarization department, and only pass verification at the national notarization department can join the federation chain.
In one possible implementation manner of the embodiment of the present application, before executing step S101, the shake-number sponsor may obtain, in advance, a private key for encrypting shake-number data from a notarization department, and the notarization structure may obtain, in advance, a public key for authenticating shake-number data encrypted by the private key from the notarization department.
Specifically, in this implementation, after the sponsor and the notarization authority pass qualification auditing at the national notarization authority, the national notarization authority issues a pair of keys to the sponsor and the notarization authority for ensuring the admission threshold and the uniqueness of the sponsor and the notarization authority on the blockchain. Wherein the pair of keys includes a private key and a public key. When the shaking number sponsor applies for the shaking number activity, the shaking number sponsor and the notarization organization simultaneously apply for the national notarization department, after the application passes, the national notarization department can issue a private key for encrypting shaking number data (shaking number participant information and shaking number information) to the shaking number sponsor, and issue a public key for decrypting and verifying the shaking number data encrypted by the private key to the notarization organization.
Thus, the node on the blockchain may receive the first shake-number data uplink request sent by the shake-number sponsor to perform the subsequent step S103. The first shake number data uplink request includes shake number data (may be shake number participant information, shake number activity information and the like) encrypted by a shake number host through a private key, and after decryption verification is performed on the encrypted shake number data through a notarization structure through a public key acquired from a notarization department, the first shake number data uplink request after verification is passed can be uplink.
It should be noted that, after the number shaking activity is completed and the related information of the number shaking is linked, the private key and the public key used at this time will be invalid. If the shaking number sponsor needs to shake the number again, the shaking number application needs to be carried out again and is checked by the national notarization department again, after the application passes, the national notarization department can issue a private key for encrypting shaking number data to the shaking number sponsor again and issue a public key for decrypting the shaking number data encrypted by the private key to the notarization institution.
S102: and receiving a second shake-number data uplink request sent by the shake-number participant, wherein the second shake-number data uplink request is uplink after passing the certification of the notarization institution.
In this embodiment, the number-shaking participant may query the number-shaking activity information issued by the number-shaking sponsor, such as the progress status of the number-shaking activity, the prize-exchanging information of the number-shaking winner, etc., through the number-shaking Application software (APP) installed on the terminal device or on the web page version number-shaking system.
Furthermore, the number shaking participants can sign an account online and fill in relevant sign information according to the inquired number shaking activity information. And sending the registration information to a shaking number sponsor and/or a notarization mechanism in the alliance chain in an intelligent contract mode so that the shaking number sponsor and/or the notarization mechanism can perform qualification verification on the shaking number participants, and after verification is passed, storing the registration information of the shaking number participants in a link.
Next, taking verification of registration information of the number rocker by the number rocker host as an example, the verification process is described, and the specific verification process comprises the following steps of:
step A: and encrypting the second shake-number data uplink request by using the private key acquired from the notarization department by the shake-number sponsor to obtain the encrypted second shake-number data uplink request.
In this embodiment, the second shake-number data uplink request is defined by the shake-number participant through the APP or the request for shake-number registration on the web page, where the registration information and the request information of the shake-number participant may be included. In order to ensure the authenticity, the effectiveness and the non-tamper property of all information data generated in the process of shaking numbers, after a shaking number participant puts forward a second shaking number data uplink request, firstly, a shaking number sponsor can encrypt the second shaking number data uplink request by using a private key acquired from a notarization to obtain an encrypted second shaking number data uplink request for executing a subsequent step B.
And (B) step (B): and authenticating the encrypted second shaking number data uplink request by using a public key acquired from a notarization department through a notarization structure.
And C, after the encrypted second shaking data uplink request is obtained in the step A, decrypting and verifying the encrypted second shaking data uplink request by utilizing a public key obtained from a notarization place through a notarization structure, and uplink the verified second shaking data uplink request.
Thus, the node on the blockchain may receive a second shake-number data uplink request sent by the shake-number participant to perform the subsequent step S103.
It can be seen that, in this embodiment, the notarization mechanism is an indispensable node on the federation chain, and if there is no node, all the information of the shake numbers sent by the shake number sponsor and the shake number participant cannot be linked, that is, all the shake number information needs to be linked by using the public key obtained from the notarization department by the notarization mechanism, so that the authenticity, validity and non-tamper-proof modification of all the information data generated in the shake number process are ensured.
S103: and carrying out number shaking according to the first number shaking data uplink request and the second number shaking data uplink request to obtain a number shaking result.
In this embodiment, after receiving the first shake number data uplink request sent by the shake number sponsor through step S102 and receiving the second shake number data uplink request sent by the shake number participant through step S101, the shake number may be further performed according to the first shake number data uplink request and the second shake number data uplink request on the chain, so as to obtain a shake number result.
Wherein a blockchain chunk includes a blockhead and a blockbody. The block header contains a parent block hash, version, timestamp, difficulty, random number, child block, merkel root, etc. The zone block contains Merkel root trees and transaction data. The information contained in the single transaction data includes information of a shaking number sponsor (such as personal information of the sponsor, public information, shaking number requirements and the like), information of a shaking number participant (such as personal information of the participant, requirements for participating in shaking numbers and the like), information of a notarization mechanism (such as organization codes of the notarization mechanism, corporate information, mechanism addresses, service ranges and the like), and the like.
S104: and receiving a third shaking data uplink request sent by the notarization mechanism, wherein the third shaking data uplink request is uplink after the notarization mechanism encrypts a shaking result.
In this embodiment, after the number shaking result is obtained through step S103, in order to ensure the authenticity, validity, and non-tamper ability of the number shaking result. The key obtained from the notarization needs to be used by the notarization authority to encrypt the wobble result and to uplink the encrypted wobble result (which is defined herein as the third wobble data uplink request). Therefore, the full-flow hasse of the number shaking process can be realized, and the number shaking process is more fair, fair and public.
In summary, according to the blockchain-based method, a blockchain node receives a first shake data uplink request sent by a shake host, wherein the first shake data uplink request is uplink after passing through certification by a notarization mechanism, then receives a second shake data uplink request sent by a shake participant, wherein the second shake data uplink request is uplink after passing through certification by the notarization mechanism, and then can shake numbers according to the first shake data uplink request and the second shake data uplink request to obtain a shake result; and further, a third shake number data uplink request to be sent by the notarization mechanism can be received, wherein the third shake number data uplink request is uplink after the notarization mechanism encrypts the shake number result. Therefore, the embodiment of the application realizes the shaking of the number based on the blockchain technology, and all shaking information on the blockchain passes through certification of the notarization organization, so that authenticity, effectiveness and non-tamper-evident property of all information data generated in the shaking process are ensured, the full-flow tracking of the shaking number is realized, the fairness, fairness and disclosure are improved, the problems of cheating and the like possibly existing in the shaking number are solved, and the public confidence of the shaking number is also improved.
It should be noted that, for ease of understanding, the overall interaction diagram of the blockchain-based shake number shown in fig. 2 is now combined. The implementation process of the blockchain-based number shaking method provided by the embodiment of the application is introduced.
As shown in fig. 2, the implementation procedure of the embodiment of the present application is: firstly, a alliance chain is built in advance based on a blockchain technology, a shaking host, a shaking participant, a notarization mechanism and the like are connected into the alliance chain according to a protocol (such as an intelligent contract), the shaking host and the notarization mechanism need to pass qualification checking at national notarization places before being up-linked, and after the checking passes, the national notarization places can issue a pair of secret keys to the shaking host and the notarization mechanism so as to ensure the admission threshold and the uniqueness of the shaking host and the notarization mechanism on the blockchain. Then, the shake number sponsor issues a need for shake number, and the need information is issued to the blockchain after being encrypted by the private key. After the shake number participant inquires about the shake number requirement by means of the shake number APP or webpage, online registration can be performed, corresponding information is filled in, after the shake number participant passes verification, the registration information is encrypted by the shake number participant through a private key and then is uplink. Or, after passing the verification of the notarization organization, the registration information can be linked, so that other organization nodes on the link can perform the consensus verification. After the shaking result is obtained by carrying out shaking, the shaking result can be encrypted and uplink through a notarization mechanism, all nodes on a chain are broadcasted, the shaking process is completed, the authenticity, the effectiveness and the non-tamper-resistance of all information data generated in the shaking process are ensured, the whole process of shaking is more fair, fair and public, and the specific implementation process is seen in the steps S101-S104.
