The aproximate computing power of current Bitcoin network in terms of FLOPS (FP32) has been estimated at about ~80,000 exaFLOPS and being aware of the limits of the analogy because of the widespread use of ASICs in Bitcoin mining. I was wondering the computing power of the main Ethereum network, which is currently running on ~8900 nodes and using Keccak256 as its main hash function, which is one that could be GPU accelerated biased toward using traditional GPUs rather than ASICs, peaks now at ~242 TH/s.

A very rough estimate would be for example:

A Nvidia 1070 Ti graphics card has a hashrate of ~31 MH/s (7.5 teraFLOPS)
Current hashrate is about ~242 TH/s
242 (TH/s) / 31 (MH/s) = 7,834,101 (~58 exaFLOPS)

So, current ETH computing power is about 58 times bigger than the current world faster supercomputer Fugaku which peaks at ~1 exaFLOPS.

Is it possible to know the actual computing power (in FLOPS) of the ETH network or sum of the underlying hardware? If we're building a peer-to-peer general purpose worldwide computer, wouldn't be nice to know current power instead of just hashing rate?

    The number of nodes is critical - you count the miners. Also the "passive" nodes are important. Here the numbers are much higher >1.100.000 (compare with etherscan.io/nodetracker) – Markus Sprunck Sep 27 '20 at 7:38

    Hey the Fugaku is actually at 0.1 exaFLOPS, so by your calculations, ETH computing is likely 580x more powerful. – Janac Meena Jul 24 at 13:46

    my mistake @JanacMeena! Thanks for pointing out. I realized it is actually half petaflop! wolframalpha.com/input/?i=537212+TFlop%2Fs+to+exaFlops – ofou 8 hours ago
