step S202, issuing block number information corresponding to the target event, wherein the block number information includes: ending a cut-off block number and a target block number participating in the target event in the block chain, wherein the cut-off block number and the target block number are numbers of blocks which are not generated on the block chain, and the target block number is larger than the cut-off block number;
the above-mentioned block number information may be distributed to the internet. The target event may be a lottery wager or other predictive event and the target block number may be the block that produced the winning number in the current lottery wager. The target block number is larger than the cut-off block number, i.e. the cut-off block is generated first and then the target block is generated on the block chain.
Step S204, before generating the ending block corresponding to the ending block number on the block chain, acquiring target prediction information provided by the target object participating in the target event, and after generating the ending block on the block chain, stopping acquiring prediction information provided by any object;
the target prediction information may be a bet number. The target prediction information of the target object may be received after the block number information is distributed to the internet, or a start time may be set. The target object may be a user who plays a lottery in the related art.
Step S206, after generating the target block corresponding to the target block number on the block chain, acquiring a hash string generated by the information recorded on the target block;
step S208, generating and issuing event actual information according to the hash string, wherein if the event actual information matches the target prediction information, a resource corresponding to a result of the matching is set to be allocated to the target object.
The event actual information may be a generated winning number, and when the winning number includes a plurality of sets of numbers, the event actual information may be partially or completely matched with the target prediction information, the partial matching corresponds to a small prize, and the complete matching corresponds to a large prize.
By adopting the scheme, the prediction event is executed on the block chain, and the value of the hash string of the block cannot be predicted, so that the advance prediction of the lottery drawing result is prevented, the artificial tampering of the actual result is avoided, the transparency and the reliability of the result are increased, and the technical problem that the prediction event is easy to cheat due to centralized guidance is solved.
Optionally, the obtaining a hash string generated by information recorded on the target block includes: acquiring information recorded in a preset time length on the target block; and carrying out hash operation on the recorded information to obtain the hash string. The information recorded in the block in the related art may be bit currency transaction data, and the information is continuously updated, and the hash string may be calculated by using the information within a predetermined time period. Since the information stored in the block in the related art is continuously updated, the generated hash value is also uncontrollable or unpredictable by manpower, and the condition that cheating cannot be performed is ensured.
Optionally, the obtaining information recorded in the target block within a predetermined time includes: a first set of information recorded directly on the target block for the predetermined duration and a second set of information broadcast by other blocks in the blockchain received and recorded by the target block for the predetermined duration are obtained. By adopting the scheme, the target block comprises a first group of information directly recorded in the target block, and also receives a second group of information of other block synchronization in the block chain network.
Optionally, when the block number information further includes a start block number for starting to participate in the target event, after a start block corresponding to the start block number is generated on the block chain, and before an end block corresponding to the end block number is generated on the block chain, target prediction information provided by a target object for participating in the target event is obtained. By adopting the scheme, the starting time is set in a mode of setting the starting block number.
Optionally, generating and publishing the event actual information according to the hash string includes: converting the last two digits of the hash string into a decimal system to obtain a first numerical value; and performing modular operation on the highest value of a value range by using the first value to obtain the actual event information, wherein the value range is the value range of the target prediction information. For example, the maximum value of the range of values of the two-digit number is 99.
Optionally, when the actual event information is multiple, the number of the target block numbers is the same as the number of the actual event information, and multiple target block numbers correspond to multiple hash strings, including: for any two first hash strings and any two second hash strings in the plurality of hash strings, under the condition that the actual information of a second event generated according to the second hash string is the same as the actual information of the first event generated according to the first hash string, taking the last two and three bits of the second hash string to perform decimal conversion to obtain a second numerical value; and performing modular operation on the highest value of the value range by using the second numerical value, and updating the actual information of the second event. In the same target event in the related technology, the lottery numbers cannot be repeated, and by adopting the scheme, the calculated actual information of the event is different.
Optionally, the obtaining a hash string generated by information recorded on the target block includes: acquiring a bitcoin transaction record recorded on the target block; and carrying out hash operation on the bit currency transaction record to obtain the hash string. The bit currency transaction records on the blocks can be generated by thousands of users, and anyone cannot predict the transaction records on the blocks, so that cheating in the process of betting the lottery ticket is avoided.
Optionally, when the event actual information is multiple, the number of the target block numbers is the same as the number of the event actual information, and generating and issuing the event actual information according to the hash string includes: and acquiring the hash string of each target block, generating actual event information according to each hash string, and forming the actual event information into the maximum prize predicted this time.
The scheme of the present application is further described below by taking the target event as a lottery ticket bet.
The embodiment of the application realizes a lottery system based on a block chain technology. In the related technology, the bit coin network generates a block about every ten minutes, the system selects a block number to be generated in the future to be disclosed on the day before the lottery is drawn, and the hash strings of the corresponding blocks are obtained through the block numbers and the lottery drawing number is calculated from the hash strings. In the process from public display to lottery drawing, the information is all from the bitcoin block chain, and the lottery system is only used as a display front end of the information, so that the aim of decentralization is fulfilled. The overall flow is shown in fig. 3, and includes the following steps:
step 1, the target block number and the cut-off block number are disclosed. And selecting a target block number which can be generated in the future and determining a block number of a bet cutoff, and showing the block numbers in the whole network. For example, the current bitcoin chunk number is 100, the chunk number of the bet cut off may be selected to be 300 (when a chunk with chunk number 300 appears in the bitcoin chunk chain, the bet is cut off), and the target chunk numbers 360, 361, 362 … are selected as the chunk numbers required for the drawing;
step 2, betting, namely, the user starts betting;
step 3, stopping the betting according to the stop block number, namely stopping the betting when the stop block number disclosed before the block number appears in the bitcoin block chain;
and 4, drawing a prize. Finding out the corresponding block in the bitcoin block chain by the previously disclosed block number, obtaining the hash string of the corresponding block, taking the last two digits of the hash string to convert into decimal numbers (assuming that the lottery value is less than or equal to 99), and taking the modulus of the highest value in the lottery value range, wherein the obtained value is the lottery number. If the same value is obtained, taking one bit before the hash string, namely the last second and third bits, and so on.
And 5, inquiring. The public can inquire the hash strings of the blocks corresponding to the public indication block numbers through various bit currency browsers and verify whether the lottery drawing result is correct or not.
In the embodiment of the application, the credibility of the lottery drawing result is ensured by using the non-tamper property of the bit currency block chain data. The bit coin block structure is shown in fig. 4 as follows: the block is divided into a block head and a block body, wherein the block head mainly comprises a version number, a father block hash value, a Merkle root, a timestamp and transaction data. The hash value here is the hash string that is later used to calculate the winning number. Where the Merkle root is used to generalize all transactions in a block, the Merkle tree is a binary hash tree, which has the obvious advantage of being more efficient by taking a branch alone (as a small tree) to check part of the data, as opposed to a hash list. Each block is also connected to a sub-block.
The digital signature scheme used by bitcoin is called elliptic curve digital signature algorithm. This algorithm has been extensively considered secure through years of careful cryptanalysis.
There are many one-way hash functions (also called hash functions), SHA-256 is a hash function that is mainly used in the bitcoin world and has good effect. First, information is stored, and in bitcoin we encounter a hash pointer, which refers to a pointer to the hash value of the data storage location and its location data. In addition, the hash pointer may also clarify the hash value of the data at a certain timestamp.
We call this data structure a blockchain by constructing a linked list with hash pointers. Bitcoins are packets of information into blocks that are connected one after the other in a unidirectional manner, where each block has both data and a hash pointer that points to the previous block. In this case, each chunk not only tells us where the value of the last chunk is, but also contains a hash digest of that value, so that we can verify that value has not changed.
The most important advantage of the above block structure is tamper resistance, which results in incorrect hash pointers for the next block if someone modifies data at any location in the blockchain. If he wishes to continue trying and to mask this tampering by tampering with the hash value of the next chunk, he needs to follow the chunk. Therefore, as long as we store the hash pointer at the head of the linked list (also called a created block) in an unchangeable place, nobody can tamper with any block without being detected.
By adopting the scheme, the scheme in the embodiment of the application utilizes the whole network openness of the bitcoin block chain to publish the block numbers which will be generated in the future in advance, each block number is exactly bound with the hash strings on the blocks, but the values of the hash strings cannot be predicted, so that people are prevented from predicting the lottery result in advance and preventing the lottery from being counterfeited in the process of lottery drawing. Meanwhile, the whole lottery drawing process and the result can be verified and inquired, so that the manual tampering is avoided, and the transparency and the reliability of the result are improved. Finally, the outcome of the draw does not require endorsement by any government or central authority, and its confidence is endorsed by all nodes on the bitcoin blockchain.
