Assumptions + slightly in depth discussion on those: https://bitcointalk.org/index.php?topic=50720.0
Seems that realistically, any entity capable of deploying a coordinated attack of more than 158PFLOPS (with some assumptions, 280PFLOPS ~= ~355.57EH/s) so 51% of the hash power of the entire network as of May 6, 2023 can successfully launch such an attack.
That’s a LOT of countries.
In fact it includes quite a few private companies with non distributed compute like IBM(who would’ve thought):

After rubbing these numbers, the network is less secure than most think and MUCH less secure than I think.
But I guess it’s more realistic to do a relative comparison of what it takes to topple the current world reserve currency vs BTC 🤔
