| Assuming the following: | |
| - A sensible pool infrastructure at 10EH/s, not 1EH/s; | |
| - A badly distributed hashrate with 50% hashrate in North America, 25% in South America, 15% in Europe, and the remainder | |
| in APAC; | |
| - A block refresh interval at 30s with a target submitted shraes for vardiff at 10s; | |
| - A network average efficiency at 30J/TH with a 3500W PSU, making it a 116.6TH/s machine; | |
| - A 19 output coinbase like ocean.xyz (just for fun). | |
| 10,000,000 TH/s (aka 10EH/s) / 116TH/s/machine = 85,764 machines |
