Odessa site fleet upgrade
Company: Cipher Mining
What the later record shows
Delivered; the record does not say when
By January 2025, Odessa ran ~11.3 EH/s at ~17.6 J/TH, down from a fleet-wide ~27.8 J/TH in July 2024. Its older rigs were later moved to Black Pearl. This points to an upgrade, but no passage gives the date or says which new machines were installed.
