> That's why gold isn't a currency there are definite transaction costs but the whole of the costs of transporting gold spent isn't required for my gold to be spent. Whole costs for transporting gold are definitely required to be spent... the gold must be transported from one owner's location to another, unless the escrow between the two parties is the same or you're actually trading ETFs. > With BTC the whole network supports all transactions and all transactions require the mining network for validation. This is true for the network as a whole, but not any given transaction. Such a model would mean that the network is topologically fully connected, which would in turn mean that it'd be orders of magnitude slower than it already is.
