Title: coin verification time Post by: scepticus on July 20, 2010, 01:14:43 PM The FAQ talks about how some coin recipents may want to wait long enough for "a few blocks to be verified' before accepting the coins.
Can anyone enlighten me what sort of time frame we are talking about here? millseconds, seconds, minutes? The FAQ didn't quantify this from what I could see. its seems a rather vital attribute to me, when thinking about the competition with traditional POS technology. Thanks.

Real-world, ordinary-sized transactions should wait a few seconds for the transaction to propagate across the network.

Real-world, ordinary-sized transactions should wait a few seconds for the transaction to propagate across the network. What happens in those few seconds if the coin was double spent? Are you notified before the next block comes in?

Are you notified before the next block comes in? I'm not personally notified, no... ;) But if I have a Bitcoin client connected to the network then yes, it (along with all the other connected clients) should be sent every transaction shortly after they happen. It has to-- it might be generating blocks, and the whole point of block generation is to record the valid transactions the client has seen that haven't been included in a previous block.There's a discussion in this thread (http://bitcointalk.org/index.php?topic=241.0) of how likely it is that an attacker could "split the network" to successfully double-spend coins. |
