Perhaps now is the time to discuss actual implementation of a reputation system. As it stand, a German scammer probably got away with some bitcoins.

I thik we might just make it simple :  a database of evaluations of market participants.  It doesn't have to be decentralised.  Google will do the job.  Here is how I see it.

All participants should be identified by a GPG public key.  Once a trade is successful, both participants should sign and publish a message such as :

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

On October, 23th 2010, I made a commercial transaction with a person whose public GPG key was IDXXXXXX.
The transaction was done without any problem.
-----BEGIN PGP SIGNATURE-----
Version: GnuPG v1.4.10 (GNU/Linux)

iEYEARECAAYFAkywLWsACgkQq17371C4DmjLUgCgvBAPXJg/mdv4PemxBRgHZ+iw
qnUAoI+bt6Nt7FG+3H/lDe9qEb4wWN0H
=rop/
-----END PGP SIGNATURE-----

I'll do this kind of things on my site (http://grondilu.freeshell.org/bitXmetal.html)


Google robots would collect all those informations, so that one could have a fairly large amount of report from any GPG ID key.

It wouldn't be perfect, but it would do the job not so bad I think.

99% of the population don't have the skills or understanding to generate and use a GPG key.

Used to be the case. And there is going to be much higher than 1% competence in the current bitcoin community. And this solution doesn't have to be the ultimate one anyway.

What prevents me from generating 10 GPG keys, publish a message with the first 9 that there was a successful trade with number 10 (and in the opposite direction) and then scam people with my 10th account which now has a fake reputation ?

Nothing,,but it might look suspicious if the 9 GPG key are referenced by only one source.

I can cross-reference all 10 of the accounts.
Your approach seems like a good idea but I think it isnt the last word on the subject.

Google peer-to-peer or p2p reputation systems and you'll see it's an active area of research, with all kinds of sophisticated schemes in development.

I don't think there's any need for the bitcoin project to get directly involved, any more than the Fed is involved in credit bureaus or the FTC. It's pretty interesting stuff though...

Bitcoiners, however, have an interest in reputation system because it is directly applicable to the bitcoin economy. We have no court and police, but the reputation of men.

True. Mainly what I'm saying is, make it a separate project, and get up to speed first on the literature, which is a lot more advanced than anything being discussed in this thread. (I'm not up to speed either, I've just skimmed.)

Bitcoin will have many uses when it gains a little age. Unlimited free (or close to it) electronic transactions worldwide. No third party to simply take a chunk for themselves.

A WORLDWIDE currency system. No US Dollar or British Pound. No exchange fee for currencies. The securities of a bank with much better privacy to go along with it.

You'll be able to use it to buy things just like paypal. Subscriptions, services, electronics. Anything you want from gold to paper plates. Pay friends with a click of a button, no fee and the utmost security.  When bitcoin gains more portability, you'll be able to "bump" phones or similar to exchange contact info and trade bitcoins through your phone (which you can already do anyways with mybitcoin.com).

The possibilities are endless. Anything you use real money for, you will be able to use bitcoins for.



I would recommend getting involved as soon as possible to get as much benefits as possible. Give it more time to blossom before you see the overall benefits.

I recommend that you take a little more care about protecting your identity.  I would suggest removing the photo and your real life address, at a minimum.

Kids these days....

"The powers of financial capitalism had another far-reaching aim, nothing less than to create a world system of financial control in private hands able to dominate the political system of each country and the economy of the world as a whole. This system was to be controlled in a feudalist fashion by the central banks of the world acting in concert, by secret agreements arrived at in frequent meetings and conferences. The apex of the systems was to be the Bank for International Settlements in Basel, Switzerland, a private bank owned and controlled by the world's central banks which were themselves private corporations. Each central bank...sought to dominate its government by its ability to control Treasury loans, to manipulate foreign exchanges, to influence the level of economic activity in the country, and to influence cooperative politicians by subsequent economic rewards in the business world."

- Carroll Quigley, CFR member, mentor to Bill Clinton, from 'Tragedy And Hope'
