I recently heard (cant remember where) that bitcoin is the largest computational achievement in history. Couldn't seem to validate this with a search. Anyone else hear this or have links to articles?
far and away, by orders of magnitude
Network hashrate is currently around 10 ExaH/s (10,000,000 TH/s) which roughly converts to 127 ZettaFLOPS, though there is no direct conversion between FLOPS (floating point operations per second) and hashes because hashes involve integer operations (whole number math) and FLOPS involving obviously floating point math. Any claim of Bticoin is x flops is simply an approximation of the potential floating point power.
At any rate, far and away the largest computational effort humanity has yet achieved. I do not think "astronomical" is hyperbole in this case.
the Bitcoin network dwarfs all extant supercomputers put together
yes, the supercomputers are still measured in PetaFLOP/s (10E15) while bitcoin is running over 100ZettaFLOP/s (10E21) estimated equivalent, believe it or don't, it is true
