I am trying to mine from cpu.
Where is the stable code for that?

the problem solved after installing cgminer from here: https://github.com/znort987/cgminer and not from here https://github.com/ckolivas/cgminer

I cannot see how the following problem is solved?
Suppose that i transfer 10BTC but 10 is kept private. How the verification that the reference transaction outputs at least 10BTC to the current input transaction?

The same appears with your proposal

I run cgminer on ubuntu but i see not output at the command line
I first successfully set up and run p2pool and then:
user@E4310:~/programs/cgminer-4.6.1$ cgminer -o http://127.0.0.1:9332 -u user -p password
user@E4310:~/programs/cgminer-4.6.1$

I am looking for relevant research manuscripts that are towards "Verifying computations with bitcoin incentives"
That is a dishonest party is given incentives in terms of bitcoins to correctly perform a computation
