Haveno Decentralised Exchange Dispute resolution (Fiat -> XMR)

In this tutorial we're going to cover how the Haveno DEX handles trade disputes, which can happen as, after all it's decentralised, and anonymous by default.

feel free to let me know if i should improve something in this one :)

@nihilist @monero Consider the following situations:
Bob and Arbitrator are colluding against Alice
Bob and Arbitrator are the same person
I think this system needs a higher authority to function properly. And there's a simple non-technical solution to this problem. If you don't agree with Arbitrator's ruling, you make the case public and provide proofs. As a result, Arbitrator's reputation is destroyed.
Someone can even create a rating service similar to @kycnotme that will list arbitrators with good reputation
- I think every arbitrator is just going to get 1 good and 1 bad review from every dispute, then.
  But, in reality, people who are happy don't leave reviews. So, likely, all arbitrators are going to have a negative rating.
- Could also have a system where multiple arbritrators separately decide on a case, say 3 arbitrators per dispute by default, and if there's a disagreement, more arbitrators decide until above x% of them agree on the resolution
  
  yea but if all the arbitrators are corrupt on the network side, no matter how many you put on the arbitration the outcome wouldnt really change right ?
- to that i would reply, that the arbitrators better be honest and behave correctly because the reputation of their network (ex:reto) is at stake, and yea definitely could be a good idea to have an external rating service, so that over time the scammy haveno networks are called out, and people avoid them
  
  exactly. haveno can be a cash cow for the arbitrators if they keep it running. The more they scam, especially on high value disputes, the higher the chance traders will just create their own network, killing the cow in the process.
  
  “pls behave”
  A hilarious joke

Awesome, appreciate these in-depth walkthroughs! Excited to see the functionality that Haveno brings to the community, and much needed now with the exit of localmonero.
- We hit 30 offers in the offer book this morning, and over 100 Monero being offered in total. And that's the first time we hit those marks. And the number of listings grew 36% in 24 hours.

So what happens if Alice is the scammer and redeemed the code but then told the arbitrator that it was invalid? Is there any protection for Bob here?
- yea as mentionned, there are a ton of difficult possible arbitration scenarios, i think there is a clear need to :
  list the payment options (like bisq did on this page here https://bisq.wiki/Payment_methods)
  detail each payment option with the correct trade protocol (which includes the precautions to PROVE that you conducted the trade correctly for the arbitrators (see localmonero's tips on cash by mail for example https://localmonero.co/cash-by-mail-tips )), the risks of the trade going wrong, and what to do in each case.
  I opened up https://github.com/haveno-dex/haveno/issues/944 just now for the same
  
  Thanks. Having all possible cases fully documented so I know all the risks and, their likelihood, and any possible or impossible mitigations is a strong prerequisite to me using it.
