For example, consider that our point total supply is 1 billion, and we send 400 million points to the blackhole at inception. Subsequently, the blackhole address will also get its own share of the 1% fee that is charged on every transaction since, technically, it also holds points. If after a month, the blackhole now holds 410 million points, having earned 10 million points from the auto-farming rewards. When we deploy points on 2nd chain, 400 million points will be recovered. The 10 million gains from auto-farming is really burned and destroyed forever. If we need to deploy more than 400 million points on the 2nd chain, we must buy back the points from 1st chain and destroy them so that the same amount can be deployed on the 2nd chain.
