This whole thread is an example of why coin devs should certainly not be claiming that 30 confirms are sufficient for mined coins - they certainly are not, especially at a launch. We're on 120 confirms at https://bltz.crunchharder.net to ensure the safety of everyones payouts - we're also actively checking that we're in consensus with the other big pools as to the block height and difficulty (ie. making sure we're on the right fork).
