i understood that previously, and raised a question for dealing with that kind of security issues to get clean (useful) currency.
if that kind of bug occurs -> wallets can be stolen, market crash, and etc, if you can transfer money from dirty wallet, a.k.a money laundering..
I suggest to insert some kind of system for upgrading wallet/client/pool to new version, to prevent direct transfer from bad/dirty client and/or wallet, what i did easily.
Also determine in currency policy what/when how coin idea deal with those kind of things. It is ok now when testcoin, but for real coin there should be some strategic rules to maintain whole process in tact
edit:
what concerns me, that dirty client and/or wallet was accepted by network... If the pool has already paid the money, and after that they have left, then they also leaves from those to whom it paid.
that was not clear to me (probably the meaning was lost for me in translation at some point).
In the post above it is valid (same) process in currency exchange sites as you described in program? Cause I bet that all participants have hope to push this coin in to the 'real' world too.
So wondering if you have developing this project in that manner, which can be implemented within a time without refreshing whole mining progress...
