A world centralized crypto is the goal they aim for but it's not secure or guaranteed right now. They have to get rid of the decentralized crypto market first. An attempt will be made to crash bitcoin and other cruptos or make every attempt to seize this market entirely. This is not going to be easy as criminal syndicates, not your average druggies and pushers, use decentralized markets heavily. They will prop up their own if needed.

The quantum tat seems to be a physical-matrix QR code and also light-based. May change or evolve based on your current information. I'd guess this design is likely more easily transferable to higher being's tech and acts like a half-way medium or technology bridge to the overwrite chip.

The "Final Chip" needs to be "alive." It adapts and actively collects and alters information of you. Also likely managed by Artificial Intelligence either by 'Legion' or Consortium. They literally have to 'augment' the sheep with a centralized crypto-tag. It's foreign carbon-based computing married into your body. That is what they want.

It starts by them blurring the technological lines between body and spirit without Humans knowing about it. This is something they could not exactly explain in the Bible to ancient human beings as they only knew of sandals and reflections.

Hell, many Humans today would not accept to understand this. That is until they are made aware.
