You’re right!

The issue with these trolls is that all that history exists publicly on the blockchain

So if someone is a troll you’ll see their transaction history of multiple blown up contracts and you’ll know to stay away

Not everyone is “rational” given the incentives, but you can choose who you play with based on how they’ve treated others

Can’t they just create multiple accounts?

You can limit account creation with KYC and have a ratings system where you can choose who to do business with (taking less risk by staying with high-rated people etc)

You're just moving goalposts here. A distributed "ratings system" has the exact same problems: fixing ratings, spamming someone with fake ratings, etc.

A rating system isn’t needed here. Just a history of transactions (% contracts successfully completed is a good metric)

+ Communities can decide who they let into these groups, or boot people who are multiple offenders

So it’s not all anonymous trolls, there’s context around each person that allows you to filter who is a troll

Can't you just game the metric and do transaction with yourself? (With other fake accounts)

That doesn't sound very decentralized at all, lol.

Why not? These are researched areas in the field and people are finding solutions to things like decentralized identities, multi-chain ratings, etc...

KYC != decentralized identities. I have never heard of anyone working on an actually-decentralized system capable of proving that you are Fred, as opposed to merely rate limiting the speed at which you can create accounts (which one might argue is sufficient, but isn't KYC). It might be that you are merely misusing the term, and meant something like sybil-resistant pseudonyms?

Doesn't sound very decentralized to me.

Copying and pasting the same comment doesn't improve the quality of discussion, it just looks like you're not actually paying attention.

Two people said the same thing and I wanted to discuss it with either

Projects like BrightID allow for rate limiting account creation through crowdsourcing real person verification.

That's where something like BrightID would help.

That provides another mechanism for abuse that cannot be fixed, or will not. Abuse via other’s id and they are left with the perpetual fallout
