Actual network bandwidth will be higher (the way the network is connected you get the same transaction multiple times from your peers). You won't be running an always-connected-network node on your iPhone, but any low-cost server will give you twenty times that bandwidth per month. And 18GB isn't much disk space in these days of terabyte hard drives.<br/><br/>A million transactions per day is a <b>LOT</b>! For comparison, in 2006 there were about <a href="http://wiki.answers.com/Q/How_many_credit_card_transactions_per_year_in_the_US">60 million credit card transactions per day in the US</a>.<br/><br/>Eventually, if Bitcoin survives and gets as popular as credit cards for paying for stuff I expect somebody will create a compatible version with a more efficient network structure (maybe by that time there will be some fancy IPV6 multicast protocol or something). And they'll implement a couple of gateway nodes (running on really fast connections) that shuttle transaction and block traffic from the current Bitcoin network into the super-efficient network. And I expect most of us will be running lightweight clients that just keep our wallets, sign transactions, and send and receive transactions to the ultra-fast nodes that ARE looking at every transaction.<br/><br/>You know, kind of like how we have those Big Routers in the Sky that handle Internet backbone traffic (or the ultra-fast DNS root servers). The Internet didn't start out with astoundingly fast routers zinging packets around.<br/></div> text/html
