Bonded/insured company for xxx value insurance per coin? Would an insurance company even touch it?

Lloyd's of London will underwrite pretty much anything.  I'd imagine the transactions would have to be pretty large before it would be efficient to insure them, though.

You honor us with your presence. Ladies and gentlemen say hello to one of the first members of the forum.

I'm of no importance at all really. Some of us just had to be here first, that's all.

I probably indirectly helped some here get very rich indeed though, myself not included.

I guess I can say that I had the honor of communicating with Satoshi though.  Cool

Anyway, lets not send this topic way of base now.

Well, I know a lot of people that would love to have talked to Satoshi directly. Don't want to off topic anymore so I'll leave you with a simple - Welcome Back!

Dead Drops - http://deaddrops.com/  Grin  Cool

Wow, that's something new. Greaat idea, not without it's problems, but still!

It's not really new though - three letter agencies have been doing this kind of stuff for years: https://wikipedia.org/wiki/Dead_drop

Combined with Geocaching it might be fun though!

Printed keypair tokens are the ultimate anonymous transaction. No way to tell if the coins changed hands, or if they are accessible by anyone at all.  Long strings of transactions could be completed with no paper trail at all, digital or otherwise.

I like the idea of a handheld radio that can send a transaction (say over GMRS or MURS, but that might not be legal) to a receiver that would then send it over the Bitcoin network.

Sure, there wouldn't be a whole lot of use for it given the ubiquity of smart phones, but I like the idea of not depending (as much) on a mobile internet connection. Not to mention the device would be Bitcoin centric and therefore more secure.

Envision a 3-D printed plastic coin that has the privkey printed inside it. The only way to get at it is to break the coin open.

It is techically feasible to design an open source 3D printer software that could be married to a custom bitcoin client. That way the privkey could be encrypted end-to-end, and the only way to know the privkey is to break open the printed coin.

That's all in the software magic.

Creating transactions offline:
 - http://brainwallet.org/#tx

Won't work, as it loads the unspent outputs of the input addresses to generate a transaction to sign.

Can you generate a 'spend all unspents' transaction without a list of input keys?
Just give the recipient your privkeys.

Which side doesn't have Internet ... the sender or the recipient (or both)?

From another thread:

In many areas of the world, there is not just limited connectivity, there is no Internet connectivity.   But does that mean those people would be shut out from using Bitcoin?

Is there a way that Bitcoin transaction can execute via sneakernet?   (i.e., the villager and his wallet stay home, but the transaction to pay was transferred to an agent which is then taken to a location that has Internet connectivity)?

The privkey would be printed on a vertical plane sandwiched closely between two other vertical planes. This way the privkey cannot be observed during the printing process.

http://bitcoincard.org/ <---this project could help.

I am concerned about the tracking abilities tho, but the video on the website says one can choose different IDs. If you can completely deactivate the device (no NFC!), as well as change the ID (not the User ID, but the ID of the device itself) or if there were no unique IDs, then this could be a really good solution.

Bad idea, whoever get their hand on the paper wallet is able to read the private key and steal the bitcoins. Send a transaction, no one can steal it
Whoever can get their hands on your paper dollars can steal them! The point is not using the internet.

I think we need bitcoin bills. 1BTC, .1 BTC, .01 BTC. If we had 1million BTC in physical bills in circulation, things would get interesting.  
Anyone got a printing press?
