Session 7 __ Psychology of cash: a world without it?

The Liffey A __ Level 1

The arms race in creating hard-to-forge banknotes was certainly challenging and entertaining. But soon it will come to an end – not because one side has won, but because it has become obsolete.

Cryptographic signatures are not only ‘hard’ to fake, trying to keep one step ahead of the forger and potentially undermining their business case. Often, they are simply impossible to fake, ruining that business case by multiple orders of magnitude. What is more, they can be produced at a fraction of the cost.

Needless to say, cryptographic signatures are now well on their way to revolutionising and securing just about everything, including payment - and cash.
