Compute 4 Cash
A commercial service that operates essentially as a private pool. The service supports connections only from the operator's proprietary Windows client which incorporates the kernel from the poclbm miner.
Compensation is calculated on a fixed "Work Unit" method.
The service had been fist operating without disclosing any relationship to Bitcoin. One of the first inquiries into the organization on February 13, 2011, yielded a response that revealed only that Compute 4 Cash was part of a distributed computing project for the financial sector.
The compensation received by the users has been calculated to be significantly less than that enjoyed by those mining using one of the public [[:Categories:Pool_Operators}mining pools]].
