The lottery drawing mode comprises a winner eating-all mode and an average mode for selection of a winning node, wherein the prize distribution rule of the average mode is that prizes are distributed averagely according to the ratio of the bet amount of all the lower bettors; the winner takes the bonus of the mode and distributes the rules to determine the bet transaction winning in the winning node according to the generated random number, and the bettor finishes the cashing through the bet transaction.
In the equipartition mode, the sum M of the bet amount of all the bet transactions on the winning node is counted, the ratio M/M of the bet amount M in the content key of each bet transaction to the sum of the bet amount of all the bet transactions on the winning node is recorded as the prize money proportion distributed by the bettors corresponding to the bet transactions, and the prize money is distributed with fair and fair.
In the winner general eating mode, the random number generation method includes but is not limited to a method that the winning node adopts a local random generation character string as the random number, and also includes other random number generation methods according to sources such as transactions, blocks and the like, but the random number is ensured to have enough entropy sources, is difficult to crack and has randomness, so that the fairness and justness of the lottery operation method of the application are ensured.

Construction method of lottery system
A set of parallel chains (which can be public chains such as permit chains, alliance chains or bits, and the like, and adopt a consensus mechanism of algorithms such as POW, DPOS, POS and the like) is built, a fixed number of tokens are generated, and the tokens are stored in a first node Pa _1 of the parallel chains. The parallel Chain in the embodiment is established by relying on a complex and beautiful public Chain33, and the public Chain33 is used as a main Chain.
Every N blocks (one lottery drawing period), the parallel Chain first node Pa _1 automatically sends a transaction to the Chain of Chain33, and the transaction is a drawing transaction. And after the lottery drawing is finished, sending the transaction to the main chain as the on-chain record of the lottery drawing result.
the parallel chain Pa comprises two types of nodes, one is a first node Pa _1 of the parallel chain, and the lottery system operated on the first node Pa _1 is as described in embodiment 4; the other is a parallel chain second node which is used as a betting platform for betting of a bettor, and the lottery system operated on the parallel chain second node is as described in embodiment 3.
in one lottery drawing period, during the first block period, initialization is carried out, tokens are transmitted to the nodes Pa _2, Pa _3, Pa _4, Pa _5, Pa _6 and Pa _7, and the token transmitting and receiving device on the second node of each parallel chain executes step S101 to transmit all the tokens to the account address of the node Pa _ 1.
the token is collected at the node Pa _1 token, and the token distribution and collection device receives tokens from the second node in each parallel chain.
During the blocks from 2 to N-3, executing step S102 for the nodes Pa _2, Pa _3, Pa _4, Pa _5, Pa _6, Pa _7 to receive the bet amount from the respective bettor, the content key records the bet amount of each bet transaction content key corresponding to the second node of the parallel chain; and the bet module simultaneously sends a transaction with the transfer amount of 0 to the node Pa _1, and the content key of the transaction records the bet amount corresponding to the bettor.
As shown in table 2, the bettor with the number B21 sends the bet amount 100 to the node Pa _2 (betting platform), the node Pa _2 sends the node Pa _1 the bet transaction Tx-B21 with the amount of 0 and the content key describing the bet amount 100 of the bettor, and Tx-B21 is used as the betting voucher of the bettor for cashing; the betting transactions of the other bettors in table 2 are analogized. The betting transaction is linked up according to the common recognition algorithm of the parallel Chain, data synchronization is kept with the main Chain Chain33, all betting transactions in one lottery drawing period are linked up, the block Chain non-falsification attribute is utilized, so that the betting transaction of each betting person is well documented, and even if the betting person forgets the betting certificate of the betting transaction, the betting person and the betting amount thereof recorded in the betting transaction content key can be found back.
TABLE 2 betting transactions for bettors
for the node Pa _1, receiving a bet, step S202 is executed, and the bet uplink module receives a bet transaction sent from each parallel chain second node.
During the N-2 block, for the node Pa _1, the token distribution executes step 203, the content key module counts the sum of the bet amounts in all the bet transactions sent from each parallel chain second node, calculates the total bet amount, calculates the ratio of the sum of the bet amounts in all the bet transactions of each parallel chain second node to the total bet amount, namely, the bet ratio corresponding to each parallel chain second node, and according to the bet ratio, the token distribution and collection device sends the corresponding share of the token to the corresponding parallel chain second node.
the contents key module statistics for node Pa _1 are shown in table 3, for the amount wagered, the bet ratio, and the number of tokens received for the second node of each parallel chain. And the bet amount of the second node of the parallel chain is the sum of the bet amounts in the bet transaction content keys sent by the corresponding second node of the parallel chain.
TABLE 3 bet amount, bet ratio, and number of tokens received for each parallel chain second node
For the nodes Pa _2, Pa _3, Pa _4, Pa _5, Pa _6, Pa _7, the token is received, step 103 is executed, and the token sending and receiving device receives the token sent by the node Pa _ 1.
during the N-1 block, the nodes Pa _2, Pa _3, Pa _4, Pa _5, Pa _6, and Pa _7 execute step 104 according to the respective numbers of received tokens, and the consensus module selects a block node as a winning node using the POS algorithm. As can be seen from Table 3, the second node of the parallel chain with the largest number of tokens is assumed to be the node Pa _2, i.e., the winning node.
During the Nth block, the winning node performs step 105, and selects a drawing mode through a selection key. And when the equipartition mode is selected, the prizes are evenly distributed according to the bet proportion of all the bettors in the node. The bonus can be an article, cash, virtual asset and the like, is determined according to bonus rules, is not limited, and does not limit the technical scheme of the application. As shown in tables 2 and 3, the statistics of the content keys on the node Pa _2 are shown in table 4, and the bet ratio of each bettor on the node Pa _2 triggers the smart contract interface corresponding to the winning method to allocate a prize to each bettor.
TABLE 4 bet ratio for each bettor on node Pa _2
The winner-who-eat-through mode is selected, the random number generator is automatically executed, and the bet transaction won in Pa _2 is determined according to the section in which the generated random number falls. The bettor completes the redemption with its own betting vouchers (betting transaction). The winning node sends the transaction to the backbone and puts winning information on the backbone.
In the above embodiment, only the betting cases of several bettors are listed, and the practical application is not limited by this embodiment, and in addition, the bettors can bet for many times through one betting platform, that is, during the 2 nd to N-3 rd blocks of one lottery drawing cycle, the bettors can have one or more betting opportunities, accordingly, one or more betting vouchers (betting transactions) can be obtained, and in addition, the bettors can also bet for many times through a plurality of different betting platforms during the 2 nd to N-3 rd blocks of one lottery drawing cycle, and these situations are not limited by this embodiment.
