Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is a flowchart of a koi lottery incentive method according to an embodiment of the present invention.
As shown in fig. 1, in this embodiment, the present invention provides a koi lottery incentive method suitable for a blockchain node, including:
s11: executing bonus donation transaction through a fancy carp contract, and storing the donated bonus into a prize pool address in the fancy carp contract; wherein, the balance of the prize pool address can not be transferred by the non-winning account;
s13: and executing a lottery drawing transaction for drawing a prize in the first block height section through the fancy carp contract:
s131: verifying whether the lottery drawing request of the lottery drawing transaction is legal:
otherwise, the lottery transaction execution fails;
if yes, go to step S132: selecting a plurality of blocks according to a pre-configured rule, and acquiring a plurality of random numbers issued by the selected blocks; wherein, the block height of the selected block is not less than the maximum block height of the first block height interval;
s133: generating a first random number and a second random number according to the obtained random numbers;
s134: determining a first block height in a first block height interval according to the first random number;
s135: determining a winning transaction in the first block of the first block height according to the second random number, and determining a transmission address of the winning transaction as a winning address;
s136: recording the winning address and the winning time into a fancy carp contract;
s15: executing prize winning transaction through a fancy carp contract, and verifying whether a prize winning request of the prize winning transaction is legal or not according to the prize winning address and the prize winning time: if so, a prize is awarded to the winning address.
Specifically, the above method will be exemplarily described below, taking as an example that each block height section includes 10000 blocks, and the user a lucky wins in the lottery cycle in which the block height section is (0,10000).
When the host of the fancy carp lottery event, or the foundation of the block chain and the project side donate the fancy carp contract with the bonus, the bonus donation transaction tx1 can be generated on any terminal, and tx1 is sent to the block chain network.
In step S11, the block link point executes tx1 by koi contract, and if the execution succeeds, the prize donated by tx1 is saved in the prize pool address of the koi contract. Assets in the prize pool address can only be distributed to the winning user by a contract when the winning user draws a prize, and cannot be governed by an administrative account or other accounts.
The sponsor of the fancy carp lottery event, or the fund of the block chain can automatically monitor the latest height of the block chain by configuring a robot program in a certain device, and when the robot program monitors that the latest height of the block chain exceeds 10000, the robot program can automatically generate a lottery drawing transaction tx2 and send the lottery drawing transaction tx2 to the block chain network. The tx2 may be configured to designate a block height interval (e.g., (0,10000), (1234,4321), (etc.) according to the rules configured by the koi contract, or may be configured not to designate a block height interval according to the rules configured by the koi contract, and the block height interval is automatically determined by the koi contract (see step S131).
In addition, when any blockchain user finds that the latest height of the blockchain exceeds 10000 and a koi contract is not yet awarded (for example, a device for configuring a robot program is down, and the like), a lottery transaction can also be generated in the user terminal and sent to the blockchain network to trigger the lottery.
In step S13, the block link point executes tx2 by a koi contract, which specifically includes:
s131, verify whether the lottery drawing request of tx2 is legal.
Specifically, when tx2 specifies a specific tile height interval, the verification of step S131 includes:
verifying whether the block height interval specified by tx2 is legal, e.g., the current latest block height is 12345, and tx2 specifies a block height interval of (0,20000), then tx2 specifies a block height interval of illegal,
it is verified whether the block height section designated by tx2 has been awarded, and when the block height section has been awarded, the award cannot be repeated, and the award winning request is illegal.
When tx2 does not specify a specific block height interval, in step S131, the block link point needs to determine the first block height interval of the tx2 requested drawing according to the rule pre-configured in the koi contract, and then verify whether the first block height interval has already been drawn, for example:
the block chain node firstly determines that block1 belongs to a block height interval (10000,20000) according to the block height 10456 of a block1 into which tx2 is packed and the number 10000 of blocks included in each block height interval, then determines a previous block height interval (0,10000) of (10000,20000) as a first block height interval, and finally verifies whether the prize is awarded (0,10000).
Among the two methods for verifying the validity of the lottery drawing transaction and the lottery drawing request, the first method for specifying the specific block height interval in the lottery drawing transaction is suitable for temporarily reaching the sponsor who plays the koi lottery drawing activities (the block height interval can be freely selected) on the block chain, and the second method for automatically determining the lottery drawing interval through the koi contract with a fixed lottery drawing period is suitable for fund clubs, project parties and the like which continuously play koi lottery drawing (the block height interval is usually fixed) on the block chain.
In the present embodiment, S132 includes: selecting a first block height interval (0,10000)]Second block of maximum block height 1000010000Obtaining a second block10000Issued third random number r10000(ii) a The specific principle of block distribution of random numbers can refer to CN201811351787.0 application, and is not described herein again. In other embodiments, the second block may be configured as any block with a block height not less than the maximum block height of the first block height interval and not greater than the rollback safety depth (to avoid rollback), which may achieve the same technical effect.
Step S133 includes: and operating the third random number according to a pre-configured first algorithm and a pre-configured second algorithm respectively to generate a first random number and a second random number. For example, take r10000Performs a certain hash operation to generate a first random number r1And, take r10000And performing another hash operation to generate a second random number r2. It will be appreciated by those skilled in the art that the first and second algorithms herein can also be configured as any transform operation method commonly used in the art, and the same technical effect can be achieved.
In another embodiment, step S132 includes: selecting a third block with a block height of 10000 plus one (10001) and 10002 respectively10001And a fourth block10002Obtaining a third block10001Fourth random number r of publications10001And a fourth blockblock10002Fifth random number r of issue10002. Similarly, the third block and the fourth block may be configured as any block having a block height not less than the maximum block height of the first block height interval and not greater than the rollback safety depth (to avoid rollback), so that the same technical effects may be achieved.
Step S133 includes: a fourth random number r10001And a fifth random number r10002Is determined as a first random number r1And a second random number r2。
In further embodiments, steps S132 and S133 may further obtain 3 or more random numbers issued by 3 or more blocks with block heights not less than the maximum block height of the first block height interval and not greater than the rollback safety depth, and generate the first random number r according to the obtained 3 or more random numbers1And a second random number r2The same technical effect can be achieved.
In step S134, according to the first random number r1Determining a first block height interval (0,10000)]First block height h of1。
E.g. h1＝0+r1% (10000-0) +1 ═ 3413, or,
h1’＝10000-(r1% (10000-0) +1) ═ 6587, and the like.
In step S135, according to the second random number r2Determining a first block height h1First block of3413Tx3, the address addr of the transmission of tx31Determined as the winning address.
For example, block3413If there are 25 transactions, the winning transaction is in block3413Wherein i is r2% 25+1 ═ 7, block3413The 7 th transaction in (1) is determined to be the winning transaction tx3, or,
i’＝25-(r2% 25+1) ═ 18, block3413The 18 th transaction in (2) is determined to be the winning transaction tx3, and so on.
In step S136, the winning address addr determined in step S135 is set1And the time of winning the prize (e.g., (1)0000,20000]Before the prize is drawn, or the block height reaches 20000, etc.) is recorded into the koi contract, the prize money is pre-distributed to addr in the koi contract according to the pre-configured prize money distribution rule1An account.
When the user A pays attention to the fancy carp lottery activity, the user side of the user A inquires the winning address and the winning time recorded in the fancy carp contract, and if the address addr of the user A is inquired1Winning a prize (and not exceeding the time of drawing a prize), a draw transaction tx4 can be generated by the private key signature of the user A, and tx4 is sent to the blockchain network.
In step S15, the tile link point executes tx4 by koi contract, verifies whether the prize drawing request of tx4 is legal according to the winning address and the prize drawing time recorded in step S136: if yes, the addr pre-distributed in the combination of the fancy carps is used1Award in account to winning address addr1。
In addition, if the winning user does not receive the prize due to the fact that the winning user does not pay attention to the fancy carp lottery event, the operator can recover the pre-distributed prize by sending a transaction after the prize receiving time is over, and the recovered prize is accumulated for the next lottery.
When the latest height of the block chain exceeds 20000/30000/…, the robot program can automatically generate the lottery transaction again and send the transaction to the block chain network to trigger the lottery in the (10000,20000]/(20000,30000]/… interval, and the specific lottery process and the prize drawing process are the same as those in the (0,10000) interval and are not described again.
In the embodiment, the random number lottery issued based on the block chain is configured on the block chain, and the koi contract taking the block height interval as the lottery cycle is configured on the block chain, so that the fairness of the koi lottery is ensured on one hand, and the situation that the koi continuously attracts the attention of the user and participates in the block chain network by the periodic high-volume reward is realized on the other hand.
