Here is how you prove a bitcoin sale.
« on: July 08, 2011, 05:56:53 am »
To prove to someone that you sent the coins to them, the easiest way would be with a video screen capture.

You can download 'Freez Screen Video Capture' for free at this web site.

Record a short video of your wallet and you sending the coins to them.  There is no way anyone can access your coins by showing them your wallet addresses, so it is perfectly safe to do this.

Upload your video on a free upload site somewhere, like Megaupload, but make sure the resolution on the video is untouched and you can still easily read what is going on.  Click here to see an example of undeniable proof of sending a bitcoin.

Also, the feedback system works great for seeing who is trustworthy.  The posts users make are non-modifiable, and when a thread link is posted in the feedback it will stay there for all to see.

Isn't linking to the blockchain.info link enough? Anyone can then see what transactions have gone to that address, even if they're unconfirmed.
For example, these are the transactions to your wallet address: http://blockchain.info/address/13Ygcd5spiSnexGkhL29y6J8EokMKX4jW9

Ah, true, that proves that transaction has taken place.  But it doesn't do much to prove that you were the sender.  The best example is when I was selling on eBay there.  I would tell the buyer to put their BTC address in the Paypal comments, and I would show a video of me sending those coins to the address in their Paypal transaction.  This proves it was the exact address given to me and the coins were indeed sent. 

The blockchain.info link is in fact better to prove the transaction has taken place and is valid, but it is hard to explain that to the people at Paypal.  They want "proof", when they ask for it, you are allowed to upload a file, a URL probably wouldn't make good proof even if it is better. 

eBay/Paypal is a bad example but it helped me in the past to do it this way.  I won 100% of the cases against me and scammers thought they could scam me but the proof I presented was irrefutable and I ended up taking advantage of them, by posting for high prices and they just paid assuming they would get their money back.

Ah, that makes sense, yes, if there's a third party involved.
If you're dealing with someone more intelligent than paypal, it would be sufficient to just let the third party and the seller know simultaneously what Bitcoin address you expect payment on (in IRC, or via a CC'd mail), and making sure the address you use hasn't been used for someone else.

I didn't know paypal would be lenient in cases where you have such proof. I thought they would ban anyone trying to trade Bitcoins, no matter what (seeing as it's against their ToS or somesuch).

Maybe I got lucky, I don't dare sell hoards of coins on eBay or even bitcents nowadays, I basically sold all my coins on eBay at like $20-25 a pop and we had fortunes of Paypal come in and literally 100% of the buyers tried to reverse the transactions.  You could imagine how much we were freaking out, having our account brought basically to zero as fast as it came in.  Luckily I made those videos for every transaction, and Paypal sided with me in every single case.  It's odd how they would allow it, but maybe I got in there just at the right time, it was sometime in July 2011 before the crash.  It was still probably new to them and they hadn't banned it yet.  Is it directly against their ToS now?

I think it explicitly bans currency conversion/transfers or something like that, but I haven't checked it myself, basically I've been avoiding paypal like the plague. SEPA is free here in Europe anyway, although it's somewhat less instant.
July might be before they got wind of it, indeed.

No problem :)  Keep in mind the video capture idea is a bit outdated, checking on the blockchain is pretty well the way to do it these days.  Back in 2011 it worked on paypal, but i think they know how bitcoin works now :)
