But how do you know which orders are correct? What if someone claims their order is correct when it actually includes someone else's chips?
To answer my own question: I think any existing orders that you keep - you should insist on a signed confirmation that the order is valid - that must be signed by
every chip payment address in the order....
@burnin:
To follow up on my own post yet again, you absolutely have to do that anyway, for all orders past and future... (Of course, maybe your website does request such verification - and I just didn't get that far.)
At least in SebastianJu's group buy, purchase was allowed by PM or public post. So in many cases the forum nick and chip payment address are both public anyway... Therefore you will need to get people to prove their identity when ordering to prevent them stealing other people's chips... Either by signing something with their bitcoin address, or by PMing you from their forum account
