At present, the average computing power of the whole network is 575.78EH/s
That's an approximation, and not a really accurate one, nobody knows what the actual hashrate is, there's no real counter anywhere, it might be off by 5% and nobody would be surprised by it, also, that number is based on the average on the last 2016 blocks, if you look at it from daily perspective it's down to 490Exa, and again this depending on which time you are cause Monday on Pacific time might have seen 156 blocks while Monday on New Delhi time 147.
