I know u can watch the transactions on blockchain.info, but what if you send an amount of bitcoins to someone and he never received it?
If bitcoin wants to become a worldwide used currency, then how is it possible that those error's still happen or can you find back where the bitcoins went? Someone got more info about that?
Grtz.
If the receiver is unable to identify the sender and has concerns about fraud, they have to wait for at least one confirmation before considering the transaction valid.
If the receiver prefers faster transactions, they can accept transactions with 0 confirmations, but then they accept the risk that the payment will vanish before it is confirmed.
There are steps the receiver can take to increase confidence that the transaction will eventually confirm.
Hopefully the larger mining pools will implement "child pays for parent" soon. It would increase their profits, and would allow the receiver of a transaction to increase the speed at which a received transaction is confirmed if they are willing to pay the fee.
