Does it? At 50M TH/s (https://www.blockchain.com/en/charts/hash-rate https://www.blockchain.com/en/charts/hash-rate) that's 10^8 TH/s, or 10^8.10^12 = 10^20 hashes per second. There's less than 10^5 seconds so surely that's only 10^25 per day. If I've messed up each of these numbers by an order of magnitude, that would leave it still well under 10^30.
2^88 is absolutely enormous.
- Dylan16807 8y agoOkay, I checked what I calculated earlier. I accidentally entered the scientific notation wrong so that was actually the number of hashes in 100 days. 10^25 is close to right for one day, and 10^25 is equal to 2^83 2^88 is both absolutely enormous and a real number that bitcoin hits in less than a year. So the point stands that a large deployment could rarely hit a 2^79 random failure case.
- IanCal 8y agoFair enough, I'd mentally worked out the 10^ -> 2^ conversion entirely wrong, sorry about that.
