U guise, let's try to move from 3 tps to 6 tps before we get all hot and bothered about supplanting the global financial system.
How many tps is SWIFT? or FedWire?

SWIFTNet Link: > 40 system transactions per second, per installation
so eliminate all the spam transactions, blockchain graffiti and sundry freeloaders and raise slowly to 8MByte by 2025 and we're done?
