Ever wonder what you could do with your private keys from past btc transactions? well you could use them to sign reviews of those transactions, or better yet reviews of the goods and/or services received.
This could be useful if you always receive bitcoin at the same address, then you could share a link to your reviews with prospective customers and request reviews from past customers... if there's any interest I could also setup an account for you to link reviews for multiple addresses to your identity and/or ssl cert,
Reviews can be created by both sender and receiver.
At the very least any feedback would be extremely appreciated!
