📝 Original message:That sounds like an interesting mechanism to help measure consensus - and a
good way to do that would help bitcoin significantly I think. I don't quite
see what the similarity is between Trust Metric and bitcoin tho. How
would you propose "building it into" bitcoin?
>From my limited searching, it looks like trust metric is basically a graph
of who trusts who, allowing you to quantify who's trusted among a
particular set or subset of people. Is that right? I would think such a
thing can be done completely separately from bitcoin, but used to answer
questions about bitcoin.
I'm curious to know specifically how the metric works and how its resistant
to adversaries, specifically how its sybil resistant. In particular I'm
curious what weaknesses it has that could be gamed. It seems sybil
resistance might be there for a while, but I can imagine that it might be
possible for a colluding set of users to farm aliases with higher and
higher reputation until they could take over the network. In bitcoin, there
are good ways of bolstering such sybil resistance, eg by charging fees for
identities in some way, or by requiring proof of funds.
