How to add customized verification?

[shadowwalkersteam]

@Kostassoid Hi. I want to add a customized verification process, I've introduced new command line argument and the process should be if I send 20 the verification will be completed at 20% instead of 100%. So everytime if I send some number the verification should take place upto that count only not 100%. Where do I need to make the change? Can you please guide a bit about the class or method where it is appropriate. Thanks.
