Bitcoin clients per default use some cpu?

[istar]

Since its possible to notice if a pool with >50% is doing something to the network.

Brainstorming.

Would it not be good if it was checked from the clients on regular occassions?
And if it happens they start to use their some cpu/gpu increasing the power of good nodes?

A lot of people will not have their gpu/cpu running in the client, so it could add quite much?

Adding to the safty of the network, making it much harder to take over.

Some people have been concerned about powerful pools with >50% of the CPU power, so I added a log of reorg events:

If someone with a lot of CPU tries to reverse transactions, it will appear in that log as several sequential blocks being replaced. A few non-sequential replacements now and then are normal.
