Wonder what the setup was...
You can see from ck solo stats that they have 10 miners:
"hashrate1m": "774T",
"hashrate5m": "833T",
"hashrate1hr": "808T",
"hashrate1d": "649T",
"hashrate7d": "189T",
"lastshare": 1677190268,
"workers": 10,
"shares": 30658943104,
"bestshare": 63795555612296.2,
"bestever": 63795555612296,
"worker": [
{
"workername": "14MooZUhqu3gXPDGC4aUh3AQFKDs3SZ1MW",
"hashrate1m": "774T",
"hashrate5m": "833T",
"hashrate1hr": "808T",
"hashrate1d": "649T",
"hashrate7d": "189T",
"lastshare": 1677190268,
"shares": 30658943104,
"bestshare": 63795555612296.2,
"bestever": 63795555612296
}
]
}
Probably they are a combination of different types of miners, but each one of those ten miners seem to be something like an Antminer S17 PRO or something like that. Basically industrial miners capable of doing dozens of hashes per second each.
