A Dyson sphere around a black hole

Because we think intelligent alien life has nothing better to do than destroy the natural beauty of star systems in order to power their crypto-coin mining rigs and video game cards. ;-)

Intelligent alien fiat systems require roughly similar size dyson spheres.

Edit to resolve Poe's law ambiguity: this is a parody. Obviously aliens would have lightning network which would require a smaller overall dyson sphere

Edited to add a winky face after reading up on Poe's law [ https://en.wikipedia.org/wiki/Poe's_law ].

You’d need a decentralised money system that can handle eventual consistency. Not because someone is too lazy to use SQL but because of the amount of time it takes to send information around. Maybe the energy itself IS the currency.

So you think an alien civilization advanced enough to build a dyson sphere would not know how to leverage it for the fundamental goal of implementing blockchain?

I guess it's true what they say: there's a sucker born every minute.
