Eigentrust++ reputation system

General Discussion
#1


What I always disliked at the NXT asset exchange/marketplace is to have no indicator on how I can trust the issuer of an asset/marketplace seller, or not.
Everything is based on beliving the issuer will hold on to his promise.

One of the announced NEM features I anticipate the most, is the Eigentrust reputation system.

I can see a huge potential for a feature like this integrated in a cryptocoin and it would make NEM a really unique coin, since I don

For what will Eigentrust be used?
To secure the network from bad nodes trying to fork/spam/do anything bad?
Or to use it as a reputation system for a AE kind of thing?

#3

Eigentrust++ is used to secure the network and is not related to the AE.


That being said, we have some ideas of how to manage trust in an asset exchange.

I probably did not understand how it works and http://en.wikipedia.org/wiki/EigenTrust shows an algorithm I don

@makoto: Thanks for the info

@DontPanic_42: With Eigentrust it is possible to determine the global trust level of a peer.

Example:
Bob knows Alice and therefore knows that he can trust her. Alex knows Bob and knows that Bob trusts Alice so he trusts Alice, too.
John now does not know Alice, Bob or Alex. So he has no idea if he could trust Alice. Eigentrust can now determine all the trust levels of all peers (Bob, Alex, …) concerning Alice and provides this global trust level to John who can now decide if he wants to do some business with Alice or not.

I hope that was understandable… :wink:
