51% attack.
@joekelly100 - his technical description is valuable - seems to understand the bitcoin protocol well enough to propose some issues to consider.
Some thoughts:
- game theory around a powerful gov attacking vs joining the network is interesting. USD is the reserve currency of the world. Why would the CCP + Russia + others “join forces” with USA to keep USD as the sound-est money? Why not just adopt a better money?
History seems to suggest that the money loosing its dominance is just replaced by the next best thing rather than adversaries coordinating to keep it going.
Game theory: not well studied in this, but here goes: good multiplayer games are fun, and difficult to predict the winner, especially if well designed and smart people playing them. Think poker, Risk, Catan. We cannot predict the outcome of government game theory around attacking vs join bitcoin network.
No country has a monopoly on smart humans. They are evenly distributed. Thus this game is impossible to predict but will be fun to watch.
I’m thinking hash power gov “wars” will mirror current open market hash competition between motivated groups of humans. It’s a brutal game. Network gains strength as they fight it out.
