From TG group:

The BOE's benefits stretch beyond enhancing transaction speeds, its greatest advantages arguably are enabling double data encryption layers and true randomization of data management. The infrastructure enables us to create true transparency and fairness for different application scenarios, we do not have to rely on software algorithms which can be breached by hackers. In future videos and on our new website we will more explicitly emphasize these features.

« Btw does BOE really take the voltage, temperature etc into account when generating random numbers? That's fucking insanely genius
- Yes it definitely does. That is exactly how we can ensure true randomness. Hence HPB is excellently suited for applications such as voting and gambling games. »

"Our idea is to get some data from the physical world through hardware, because the physical world is an irremovable dimension. There are hardware in our system, and the data of the physical world such as voltage and temperature is collected through hardware, so that the random number that is truly non-removable is obtained.

The random number mainly includes three aspects: the first aspect collects the voltage temperature, and then takes several decimal places to get a random number. The second fully combines the mechanism of the blockchain consensus process, and adds the random value, plus the previous random number, to generate the random number of the current blockchain, and makes a second security guarantee. Third, if you want to get this random number, what do you do? You need to take the value of the previous block to guess, the time left for you is very short, and these values are unpredictable, even if you get it, you have to be able to verify it. Once you find that you are doing it, you will be taken The data is discarded. Therefore, through these three points, the hardware random number is completely guaranteed.

Random numbers seem to be a topic of comparative technology, and a few examples are helpful to understand. For example, your welfare lottery, or real estate lottery, if these things have a very feasible process, we are willing to participate, once the real questioning problem is solved, including finance, including many key scenarios, it is possible to build on the blockchain."
