This is avery valid concern and I hope it’s being addressed in the whitepaper. Traditional blockchains have a limited space in each block which means there is a max number of transactions that can be processed. like 5-7 for bitcoin or 15-20 for ethereum. When the blocks get full transaction fee go up as a way to prioritise transactions to be settled. It would be great if Safex Cash would offer an innovative solution to blockchain scaling so that the system would not suffer from scaling issues by design. @dandabek would you give us some insight on the direction you are going?
