We’ve also gained some other important insights that will be relevant to the business case for this type of DLT application:

Most cost savings appear unlikely to come in the core system itself, but rather more likely through reducing bank reconciliation efforts. The initial design is quite collateral intensive while the current system is already highly efficient. There's the potential for more savings if other applications could be built on top of a core cash payment distributed ledger system (eg financial asset clearing and settlement, trade finance). In an actual production system, trade-offs will need to be resolved between how widely data and transactions are verified by members of the system, and how widely information is shared. While DLT may aim to reduce concentration of risk, a substantial amount of centralization would still be required (eg permissioning of nodes and setting of operational standards) if applied to wholesale payments systems.

Under normal circumstances I would have simply walked out, feeling it wholly inappropriate to reward such a poorly managed establishment and, as a functioning actor in a capitalist economy, done my duty to depress their lunchtime takings. Here’s what we wanted to say: This is absurd. This is 2016 not 1916. Your card machine is down? Well, so what! Are you seriously telling me that mein host has no mobile phone number capable of registering for PingIt or PayM? That none of the staff or the pub itself have a PayPal account that I can send the money to? That neither the owners nor managers not contingency planners thought to tuck an iZettle behind the bar to use when the clunky and expensive GPRS terminal fails for o...
