That's so boring.
Nobody outside small blockers mind is talking about a 100 petabyte blockchain.
If we ever need this space that there will be now way around some kind of centralization, be it lightning, sidechains or blocksize. And, to be honest, if we are in this scenario, a big blocksize may be NOT the most centralized vision.
But that doesn't matter. Nobody is talking aboutz 100 petabyte blocks. End of the story.
I`m not talking about block size but the size of the entire blockchain.
It's already 60 GB, and its growing. If you wanna raise the block size to 8-16 mb later, it will grow rapidly.
You are talking about small people not having room for transaction. But nodes not having HDD room for blockchain that is ok no?
Well it isnt, the blockchain must stay as small as possible, because otherwise it will grow faster than MOORES LAW or other pseudoscience, and you will quickly find out that only datacenters could host bitcoin in the future.
