Something like a GPG ring of trust, with addresses signing other\naddresses would work well, if some sort of Stealth address or HD wallet\nroot was the identity gaining the reputation, then address re-use wouldn't\nhave to be mandatory.\n-------------- next part --------------\nAn HTML attachment was scrubbed...\nURL: \u003chttp://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20140306/566df540/attachment.html\u003e"}
