As a random whim, I want to see if it's possible to send one satoshi to every bitcoin address that's ever been used. How much would that be? I'm betting the transaction fee would be a lot more, though. Is this even possible? How would I do it?
Is it possible to send one satoshi to every bitcoin address?

Yes. There are currently about 10 million unique addresses in the block chain, so 0.1 BTC would be enough to send a satoshi to each address. The transaction data would be about 340 MB. The network's anti-spam protections would make this project either very expensive (due to transaction fees) or very time-consuming.
How do you know there are 10 million unique addresses? – Shamoon – 2013-11-27T21:31:44.487
@Shamoon I gathered that data from the block chain. – theymos – 2013-11-27T21:51:51.710
@theymos Is it up on blockchain.info anywhere? – Shamoon – 2013-11-27T21:53:27.187
@Shamoon I don't know. I didn't get the info from a website. – theymos – 2013-11-27T22:43:22.623
It's weird. I got a 1 satoshi transaction from 1Enjoy1C4bYBr3tN4sMKxvvJDqG8NkdR4Z. You don't need to provide a transaction fee, but it might be quite a while before a miner decides to process it. – Chloe – 2014-02-23T20:45:12.837
Thanks! So it's infeasible. =( As an estimate, how much do you think the transaction fee would be? – lurf jurv – 2013-02-08T15:55:11.720
4@lurfjurv It's not infeasible. The fee might be about 170 BTC, though this depends on many factors. – theymos – 2013-02-08T17:20:22.867
Hm.. kind of multicast. I am not sure how useful this could be, but it is not possible now. You need to create as many transactions required. – vi.su. – 2013-02-08T06:31:08.597
