Company: Cipher Mining - Project: Chief Facility
What the later record shows
Delivered; the record does not say when
The FY2024 10-K says both Bear and Chief were expanded from 10 MW to 40 MW in 2024, which is the promised 30 MW at each site. No passage says whether this was done by the Q2 2024 target or later in the year.
“The Chief Facility was expanded from 10 MW to 40 MW in 2024. It is capable of hashing at a rate of up to approximately 1.6 EH/s.”
