Hi Guys,
I've been working on this idea for a reputation system on top of the bitcoin network.
The basic idea is an append-only database of claims. Claims have a source, data, and a target. The source and target are bitcoin key pairs.
You can think of it as an extension of Zimmerman's web of trust. Swap out PGP keys for bitcoin keypairs, extend the idea of key signing to making a claim of any kind, and put that data into the bitcoin blockchain using the OP_RETURN.
I found it easier to build the basic idea out in ethereum, and I've put the code out under the GNU GPL;
https://github.com/btalabs/trustnetI've also written a bit more about it here;
http://bittradelabs.com/blog/lego-for-grownupshttp://bittradelabs.com/blog/finding-analogiesI'm looking for feedback and potential collaborators.
I've also written a draft white-paper suggesting an implementation for bitcoin, which I can send to whomever may be interested.
Thank you,
Hugo
