Your whitepaper does not describe how a "nominal" registration fee (easily afforded by scammers) completely eliminates the possibility of Sybil attacks, aka "the absence of reliable reputation information". Are moderators going to make the fee so high and the requirements so stringent that they can afford to fly out and personally run live fingerprints, DNA, retinal scan? And having to trust moderators to kill Sybils is only "trustless" if it means "trust less than 100% but more than 0%".
You can never 'completely eliminate the possibility' of a Sybil attack on any reputation system .
The whole idea of MAD is that -both- parties have something to lose by being a dishonest trader.
In your scenario, the scamming buyer loses out on some kind of security deposit put in escrow before the trade.
The whole point of the security deposit is to incentivize honest behavior.
This goal is achieved in a different way with METAmarket.
Rather than scammers being incentivized by security deposits,
they're incentivized by the potential to lose their registration fee,
and
whatever time/effort/BTC has been burned building their current identity's reputation.Here's a quote from Jeremy Spilman (also quoted in the white paper):
The first option is to lock up some of Bob’s coins along with Alice’s. That way, Bob can’t simply troll Alice into losing money without losing some of his own. Technically, what we need to do is collect properly sized inputs (account balances) from both Alice and Bob, and then collect all the coins together into a single multisig output.
...
The second option is to setup an automatic release from the escrow where coins are either sent back to Alice, or split some way between Alice and Bob, at some predefined points in the future.
Scammers don't care about reputation, they use/buy new accounts all the time.
I don't think your market will work well in that section.
Have a look in these forums and you will see that some Sr. and Hero members are nhot really who they were when they created the account.
It is sold accounts that were bought by others for one of two reasons: Signature campaigns, or to scam others.
