Vitalik JUST POSTED: My rough math based on average difficulty stats suggests that Bitcoin mining crossed the total 2**96 hashes milestone very recently?
Seems like a good reason to insist on (close to) 128 bit security.

OUR THOUGHT: Interesting take from #Vitalik hitting the 2⁹⁶ total hashes milestone really puts Bitcoin’s mining history into perspective.
Revisiting security assumptions toward ~128-bit makes sense if we’re thinking long-term resilience, not just present-day safety.
