Problem is we already have Bitcoin breaking records with 4 million txns per day record, 1500 TPS, multiple 32-64 MB blocks. Investors pay a premium for what is happening not promised
But I've seen other saying that Graphene saves 99%... So I'm not sure if I should trust that 10% that the whitepaper mentions. Maybe "compact blocks" is a form that is already comprsd.
Not sure. Very roughly, Graphene is 10% the size of compact blocks according to the whitepaper, and I think that a compact block would mean ~250bytes*1000200=238MB. So about 1%.
