Vircurex is another. Can we not vote for two - I'd suggest also MtGox despite everything I'm not in for quick profit, so don't mind noobs loosing to HFT leeches.

Noob rule for newbies eh?

Where a part of the network is isolated - unlikely perhaps, then a minor network physically local to the major network could see the same private key with neither customer or vendor being aware. Perhaps if the card held the balance, that would avoid innocent errors or missing communication.

I think perhaps I'm still to get my head around how a debit card could work. If you contact the same node, it'll obviously be aware of the previous transactions; if you use a private key to contact a node that hasn't caught the latest transactions, those transactions won't be taken into account?

hmm.. perhaps it's unlikely to ever be an issue that couldn't be written off but I wonder that people using only their private keys and not a node; so debit cards for example, could do this unwittingly and then the innocent vendor that's in the minor network, for no fault of their own, might lose transactions?

Bitcoin makes a lot of sense and I'm looking then to understand how Bitcoin works in extreme scenarios; to have confidence in it's ability to be robust, I think that's necessary.


If there was a real world disruption to the internet and two bitcoin networks were running in isolation; each with enough instances to confirm transactions, then is there a risk that two instances of the same wallet could be used either side of the border and a wallet could then double spend?

Thanks!

I'm just synchronising and it's taking a while. Does each user holds detail of all transactions or are they limited in some way to network neighbours?

Also, a note that I've just had to renice the bitcoin process.. :/

Then, if I want to accept Bitcoins from public, is it wise to declare a single address for that? Is suggesting the address sufficient?? I've seen advice for websites accepting Bitcoins that suggests using third party and even hosting bitcoin servers for it but I'm wondering why anything directly is needed, especially if its low number of transactions; surely the bitcoin community stands alone and merchants in theory don't need anything themselves - although obviously in practice having those using it, hosting capability is important.
