So Bitcoin cannot trivially be subject to a 51% attack, certainly not by Sweden anyway.

~~~ So awesome, I have to make an account to see the dead comment. Way to go HN mods.




Hashing power is not directly equal to power consumption

Sweden may hypothetically purchase miners 2x more efficient than the average miner and therefore need only half their countries power output.

In addition I would be surprised if Sweden can't source power from other countries ( prove me wrong I'm not sure on this one)

They absolutely can, though I think they've been mostly net exporters for the last ~10 years.

According to https://www.svk.se/siteassets/drift-av-stamnatet/bilder/map-..., Sweden has 7 HVDC (Denmark x2, Germany x1, Poland x1, Lithuania x1, Finland x2) plus 2x 400kV to Denmark, 2x to Finland and 4x to Norway (plus a 220kV).


The latest miners are running on 10nm technology. So unless Switzerland can start manufacturing 4-5nm devices right away, what you said is basically impossible. Also, if the Switzerland government by any chance acquires 4-5nm technology, what will keep the miners from doing that too? You would be surprised how deep their pockets are. Well they all paying all of Switzerland's electricity bill, so that might give you an idea.
