The WoT appears to be subject to scammer infiltration as well, though infinitely better than blind trust.
This is my main issue with WoT. Very vulnerable to shills/hackers/scammers.
I guess what I'm really asking is, "Is there a way to specifically establish a level of trust for a given
issuer in a decentralized, quantifiable way?" How about a system similar to a consumer credit rating
or a DNB rating for a business? Does WoT really address this completely?
Yes WoT is the solution to that specific problem. But it is far from perfect at its present state.
This is another topic for intense debate but unrelated to the purpose of the colored coin protocol.
