You will need a blockchain, though. Or someone you trust, who has a copy, and whom you can communicate with, and who has connections to other peers.

I believe that is included, if I read this right:

https://en.bitcoin.it/wiki/Block_chain

If I am wrong, someone please correct me.

Currently 1.75 GB, and growing.
http://blockchain.info/charts/blocks-size

Or just check the size of the Bitcoin folder on your PC.

I have the entire blockchain on 3 separate laptops that run 24/7 but i was thiking of ditching the lot
and switching to multibit or electrum

is it of any benefit to the network for most people to be running the full client and blockchain or could almost
everyone switch to a lite weight wallet that only downloads the block info but not the entire block ?

the 51% attack is harder the more people are running a full copy of the blockchain, is that correct ?

Clients aren't really heavy on bandwidth either, even if the GSM network goes down a 56k modem could keep things up to date and would probably be enough for a blockchain only access point.

I was thinking a sat-link.

Try an android or tizen or meego based smartphone. They are all based on Linux.

There is more to Bitcoin than bitcoins.

You are all missing my point because you are obsessing over irrelevant details. Here is a relevant detail, along the line of your comments: electricity or not, Bitcoin currently doesn't work for point-of-sale payments. In most places there are zero merchants accepting BTC. But that's not the point of this thread. The point is, could Bitcoin still work in case of blackouts, and if so, could it be more resilient than centralized credit card networks?
My estimate above: no.

Mobile is relevant.

Part of your thoughts on "merchants" is being worked on as you read this. Something like this → http://digimo.biz/

Mobile is equally relevant for Bitcoin and for credit cards. There is no advantage of one over another in case of blackouts.

I added a bit before you replied. There should be a POS system similar to this ( http://digimo.biz/ ) soon.

Bitcoin does no better. Even bitcard does not better. At some point you need to connect to the wider internet. If your bitcoin merchant terminal can do that then so can your CC merchant terminal. If it can't then unless you plan on accepting unconfirmed transactions which may be double spends you are just as dead in the water.

apparently the bitcoincard network scales without problem. So in the case the bitcoincard net covers the whole city, there needs to be only one gateway (or connected blockchain server), which is a much weaker demand than network access at each merchant.

So in that case the bitcoincard does indeed better.

Is that digimo thingy using bitcoin already? I don't see anything much in the 'how it works' section but whats there could be running on bitcoin.

Worried what would happen if com's broke down long enough for the blockchain to split to, isn't there a system in development to allow splits and merges though?

Digimo was just an example I used. I liked the fact that no extra hardware is needed to make their system work. PM me if you want more info.

My estimate above: no.

That is if the merchant is prepared and has access to one of those card swipers (either the Square dongle or the dedicated one you referenced). Though with a Square account you can also do Card Not Present transactions to then manually enter the card.

But you are likely correct -- as long as there is even just mobile communications and battery powered mobile tablet laptop devices, the existing payment systems can continue to function even with an extended power outage. Bitcoin doesn't really offer merchants anything they need in this scenario.

As far as enabling person-to-person exchange if the ATMs are down, I still think Bitcoin is uniquely positioned for that.
