Is it feasible to draw out lottery numbers and seal them first, then sell lottery tickets, and then make the numbers public?

This idea is completely unfeasible. It is just like the lottery draw when the phone is turned off. It is purely a layman's talk.

1. There is no secret to rolling out the numbers in advance

To know that the numbers are drawn out in advance, someone must be involved and someone knows. If someone knew the lottery numbers, how could they not be tempted by such a huge bonus? As long as you secretly pass on the number and find someone to buy it, you can receive the prize openly, so this is definitely not feasible.

Obviously, this method is a complete joke compared to post-sale lottery drawing. After the sales stopped, there were still a lot of doubts about the live broadcast of the lottery. If this method is adopted, there is no need to question it, there will be problems 100%.

2. It is easy for hackers to succeed when the machine is turned off and the lottery is drawn.

Compared with the lottery in advance, the lottery is drawn after the machine is turned off. Unfortunately, it is still a layman's term.

The period between the sales stop and the lottery draw can be long or short, but it must be there, and it cannot be too short. It must be at least 30 minutes. This is not for so-called retrieval of data, but mainly for saving data separately.

Generally speaking, the sales data of each province in the national joint sales method must be stored in three places: the provincial center, the China Welfare Lottery Center or the China Sports Lottery Center, and the notary office at the lottery site; each place It is necessary to save several copies separately: in the sales system or a computer connected to the Internet, in a non-rewritable CD, and in a computer physically isolated from the Internet. After the lottery is drawn, these data will be retrieved separately to ensure that the winning situation is consistent. The data has not been overwritten.

This kind of operation can avoid hacker intrusion or staff tampering. This cannot be achieved by shutting down the machine and drawing the lottery immediately, so it is purely a layman's talk.

The current lottery rules have been refined and are currently the most accepted by the market and lottery players, basically ensuring safety and openness. If there are better and more practical suggestions, I believe the lottery agency will adopt them, but at least they must be real, feasible and reasonable!
