> How is this expected to work with 7 billion people using it for every tiny financial transaction? I don't think it can. Give it ~30 years, for the cost of CPU time/storage space/internet speed to cost 0.1% of what it does today, and — in combination with off-chain clearing — this becomes feasible. For Bitcoin to even work as money in the first place, people need to store their savings in bitcoins. This transition will take at least ~30 years anyway, which leaves ample time for computing costs to fall to a level where 1GB blocks are realistic. Combined with an off-chain clearing protocol (like Stroem[1]) for consumer-to-merchant payments, this should allow Bitcoin to scale to ~10bn people.
