Bitcoin miner Stronghold Digital (SDIG) is to host 4,000 mining machines supplied by Cantaloupe Digital, a subsidiary of rig maker Canaan (CAN).

The 2,000 A1246 and 2,000 A1346 miners will provide a total capacity of 400 petahash per second (PH/S), according to an emailed announcement on Thursday. The A1246 miners will be installed by May 15, while the A1346 miners will be installed by a month later.

Stronghold has procured around 22,000 miners since August with capacity of 2.2 exahash per second (EH/s) at a cost of $15 million, CEO Greg Beard said.

As part of the two-year hosting agreement with Canaan, Stronghold will receive 50% of the bitcoin mined and retain any upside of selling power back to the grid, should the company elect to curtail the usage of the machines to do so.
