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 first 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.
