Lols... Your first paragraph really got me laughing, how can an alien create such a advance technological system? 😂😂😂

Halving, from what I understand, is a process that causes bitcoin miners to receive half of what they previously received as a reward for mining the bitcoin blockchain blocks. There will be exactly 34 halvings. By that time the miners will not receive any bitcoin for their mining process, they will only receive payment for the transactions (this will probably be by the year 2140, so I don't think it will be our problem anymore).

The miners are really gaining more influence by their mining actions though but I'm quite astonished about miners receiving their payments in the year 2140.. That's really still very far
