Can Blockjack be copied on this blockchain? Must be nice, playing with a lower fee.
Yes, technically any kind of gambling app could be built on the Rise blockchain, including Blackjack as you suggested.
The very difficult part is how to program a truly random number generator without having any deterministic element in the outcomes so that the games are truly fair. Gambling apps often use PRNGs (Pseudo Random Number Generators). As the name implies they are 'Pseudo', meaning they are not truly random and the results could potentially be simulated, predicted and then exploited. PRNGs take an initial number, known as a seed, and then mash it together with various hidden and shifting inputs—the time from a machine’s internal clock, for example—in order to produce a result that appears impossible to forecast. But if hackers can identify the various ingredients in that mathematical stew, they can potentially predict a PRNG’s output.
A true random number generator must be rooted in a phenomenon that is not man-made, such as radioactive decay.
Building a true random number generator can, to my knowledge, not be built without leaving the decentralized environment. You need to utilize a centralized source, such as a service like
https://www.random.org provides.
