The high-efficiency and safe Solana block chain enables a large number of personnel to participate or the block chain system for starting the lottery at different frequencies to be possible due to the high-efficiency transaction rate and the block-out time of the Solana block chain. Meanwhile, the unique history proves that the safety is higher.
Under the background of continuous progress and improvement of various network intelligent technologies and national self-consciousness, more and more decisions, votes and swabs are applied to various parts of our lives, such as house-buying lottery numbers, license plate lottery numbers, market lottery or various competition lottery numbers and the like. There is therefore a need for a drawing method that is more reliable, transparent and verifiable.

secondly, deploying an intelligent contract B on a Solana block chain; on the basis of the intelligent contract A, the user/activity host is coded according to the drawing rule and then deployed on the Solana block chain;
thirdly, operating the drawing system; a signing rule is transmitted to the intelligent contract B, and then a private key signature is carried out and submitted to a Solana block chain to start a drawing event; when the block height reaches the block number corresponding to the lottery drawing time, the intelligent contract A extracts the Seed corresponding to the digit according to the contract rule and transmits the Seed into the intelligent contract B, and the system for carrying out the contract by the Seed provided by the intelligent contract A, the drawing rule provided by the intelligent contract B and the transmitted drawing rule completes a complete drawing event;
and fourthly, the user/event host performs private key signature triggering result publicity.
Preferably, in the first step, the number of digits is set according to the needs of the user/event host.
Preferably, in step three, the signing rule includes: the number of participants, the number of Chinese signs, the time of drawing a prize, and the number of Seed.
Preferably, in step three, when the drawing event is started, the drawing rule and the middle drawing rule are both transparently disclosed to the block chain.
Preferably, in step four, when any person with objection can apply for the third party to perform public verification after the result is disclosed, anyone can independently run the drawing program of the Seed value + the drawing rule in the intelligent contract B + to perform the result of the drawing system for re-verification.
The invention utilizes the Solana block chain technology to carry out on-chain deployment and HASH as Seed to participate in transparent calculation on the traditional lottery system, thereby fully ensuring the full transparentization of the processes of running, setting, lottery drawing and the like of the lottery system and the risk of no black box operation. And the characteristics of non-tampering and permanent retention of the block chain data are fully utilized, and the fact that any drawing event can be verified again and inquired permanently in the future is guaranteed. This drawing system may be used in major events or decisions to increase the confidence level for all participants.
Drawings
Fig. 1 is a flowchart of a method for implementing intelligent contract drawing based on the Solana blockchain technology.
Detailed Description
For a further understanding of the invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings and examples. It is to be understood that the examples are illustrative of the invention and not limiting.
Example 1
As shown in fig. 1, the present embodiment provides a method for implementing intelligent contract drawing based on the Solana blockchain technology, which includes the following steps:
firstly, deploying an intelligent contract A on a Solana block chain; the intelligent contract A processes and appoints the digital extraction of the Solana block HASH in the future according to a certain rule, and the digit number which is only a number is extracted from the HASH and is used as the Seed to be provided to the drawing system; the digit number of the number is set according to the requirement of the user/event host, for example, [ 79eHuWE2LTK1ngmykr9E1jn5o9GJrqb6qSUQUG2u7Czw ] needs 5 digits, and after the appointed hash is out of blocks, the provided seed value is 79219 (if the digit number is not enough, the contract automatically postpones the selection of the digit of the hash of the next block for digit splicing, because the TPS with high efficiency of Solana does not wait for too long a time millisecond level). And after the intelligent contract A is deployed, providing a corresponding request interface for the system call of the drawing and signing algorithm.
Secondly, deploying an intelligent contract B on the Solana block chain; on the basis of the intelligent contract A, the user/activity host is coded according to the drawing rule and then deployed on the Solana block chain; meanwhile, the Seed value of the lottery rule calculation parameter is obtained through the API interface of the intelligent contract A, because the block HASH in the future is unpredictable, the absolute fairness of the Seed in the lottery system is ensured, and the intelligent contract A needs to be transmitted with the bit number of specific parameters such as the Seed value (the higher the bit number is, the greater the violent enumeration difficulty of the lottery result) and the block or time for drawing the prize.
Thirdly, operating the drawing system; after the intelligent contracts of the A and the B are deployed, the contract system on the chain is in a state to be run, and when the drawing system is started, drawing rules, such as the number of participants, the number of drawing persons, the lottery drawing time and the Seed number, are transmitted to the intelligent contract B. Then, carrying out private key signature and submitting the private key signature to a Solana block chain to start a drawing event, wherein the drawing rule and the middle drawing rule are both transparently disclosed to the block chain; when the block height reaches the block number corresponding to the lottery drawing time, the intelligent contract A extracts the Seed corresponding to the digit according to the contract rule and transmits the Seed into the intelligent contract B, and the system for carrying out the contract by the Seed provided by the intelligent contract A, the drawing rule provided by the intelligent contract B and the transmitted drawing rule completes a complete drawing event;
and fourthly, the user/the event host performs private key signature triggering result publicity.
Because the block chain cannot automatically trigger the operation and the display of the system, when the public result is reached, the private key signature triggering result display needs to be carried out by the lottery event host, and the display mode of the result can be independently determined by a person using the system.
When any objection person can apply for the public verification by a third party after the result is disclosed, the HASH of the drawing is disclosed, namely the Seed value is determined. The drawing algorithm rule and the input drawing rule of the intelligent contract B are also determined, and anyone can independently run the drawing program of the Seed value + the intelligent contract B + the drawing rule to verify the result of the drawing system again.
In the embodiment, a Solana block chain technology is used for carrying out on-chain deployment and HASH on a traditional drawing system as Seed participation transparent calculation, so that the full transparence of the processes of running, setting, drawing prizes and the like of the drawing system and the risk of black-box-free operation are fully ensured. And the characteristics of non-tampering and permanent retention of the block chain data are fully utilized, and the fact that any drawing event can be verified again and inquired permanently in the future is guaranteed. This drawing system may be used in major events or decisions to increase the confidence level for all participants.
The present invention and its embodiments have been described above schematically, without limitation, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching, without departing from the spirit of the invention, the person skilled in the art shall not inventively design the similar structural modes and embodiments to the technical solution, but shall fall within the scope of the invention.
