Title: How can I prove that a bitcoin transfer was made?
Post by: wingding on March 17, 2013, 10:09:06 AM
Can I prove that I made a bitcoin transfer to a particular address? Say, for example in case of a legal dispute. I am asking for something more substantial than a screenshot of my wallet. I understand that all transactions somehow ar stored on the network?

Double klick on you transaction, you get a TX-ID.

Think of the block chain as one huge, international ledger. All bitcoin transactions are permanently recorded.

Blockchain.info is currently the best website to look up transactions, as shown above. You can also see all transaction to and from your address by going to:

Then the question is, how can you prove to the person you paid that the address was one that they gave you to pay?

And the answer to that:

We need a payment protocol with non-repudiation built in.

See https://gist.github.com/2217885 for a multisig version (the singlesig version is simpler, but the merchant <-> customer communication will be the same).


And a variation of which is being developed now.  The Development mailing list has a thread on the topic.
