> How does increasing the mining difficulty affect the time it takes to scan a passport in line at the airport? It doesn't. The idea is not to change the actual passport, is to change the software that uses the passport to perform these calculations. That software would have to ask the passport to do 10000x operations instead of 100x. But each would take the same time as before.
