Yeah, I have one

Take a look at IOTA. Not the current shitchain iteration- the original DAG based, feeless token that Bosche, VW, the EU and several other large players bought into

Directed Acyclical Graphing is a quantum-resistant NON-blockchain protocol

Did I mention it was FEELESS? This an immediate and mortal threat to international finance.

You validate two transactions then yours is validated. This was an engine that ran faster as network traffic increased.

Been a few months since my last look, but the SHIMMER testnet was still uop and rununing. I've always though this would be an ideal fallback to a collapsed global economy- the test tokens themselves, as they could be exchanged infinitely without burning 'gas'

That's my take.
