We discussed:

• Bugs:

  • java.lang.IllegalStateException: Expected PENDING or IN_CONFLICT, was BUILDING
    • unable to start bisq: java.lang.IllegalStateException: Expected PENDING or IN_CONFLICT, was BUILDING bisq#5050
    • java.lang.IllegalStateException bisq#3117
    • java.lang.IllegalStateException on startup bisq#3072
    • Error starting Bisq: java.lang.IllegalStateException #257
    • Withdrawal not propagating, funds not accessable per cmd-e bisq#2778
    • Possible sollutions:
      • Resync SPV
      • Restore from seedphrase
  • Seller can't confirm because message isn't released
    We revisted @jmacxx 's preview pull request to resend the message
    • a possible sollution is to have the BTC seller have the option to release the funds from the start of the trade without requiring the BTC buyer to have to clickj Payment Started

• Suggestions:

  • Have details of the proposal shown to users when the dispute is closed. Right now it isn't cleary expressed to the traders what they are accepting when a mediator makes a payout suggestion. We should improve that.
  • Add a "Move funds to external wallet" screen to end of dispute just like at the end of a normal trade
    @huey735 pointed out that that screen may be unnecesarry even in the normal course of events. The payout from the trade always sends the funds to the trader's wallet where they can withdraw from. This screen may give the wrong impression and may be not necessary at all.

• Limit Cash by Mail by country
  Currently offers of Cash by Mail can be accepted by everyone despite their locations. We see as an improvement to restrict it to national borders. @jmacxx will investigate the best way to do so.
  @RififiCastorjunior mentioned that Cash by Mail between the EU countries works fine so maybe it's worth considering EU as a single zone and allow traders in those countries to trade between themselves

• Add options to traders for suggesting payout between them to avoid mediation
  @huey735 mentioned that this made sense and that it should reduce the responsabilities for Mediators and speed up a lot of the Mediation cases. The arguments against it is that it may betoo complex for the traders and it may open the opportunity for social engineering between the traders which will lead to unintended outcomes.

• Add reputation to traders
  Once again the reputation for traders was mentioned and its main criticism was brought up: maybe it breaks anonimity. Right now the tools available are too harsh. A trader is only able to block another one from taking their offers.
  A system where an offer maker would be able to specify that a trader with less than 3 stars would be unable to take their offers would be great.

• Do a call with traders
  The voice of Bisq traders isn't that clear and more live calls like Bisq Demo Session, Episode 1 would be a great way to answer some of their most pressing questions

• Reocurring issues
  • Seller ablity to withold till the end of Mediation is still a problem without a good sollution (option trade)
    • Bisq allows seller to omit mediation bisq#4162
    • Deactive confirm buttons once mediation started bisq#4493
    • Revert "Deactive confirm buttons once mediation started" bisq#4562
    • Re activate confirm buttons again bisq#4602
      Current state

       	- Enable for buyer and altcoin seller at all times (only once arbitration is opened it is disabled as there is no way anyway to do a normal payout anymore.
      
       	- Disable for fiat seller while mediation is open. Enable it at dispute result if no penalty was applied by mediators (derived from payout suggestion). So the mediator is the enabler for the confirm-button by his judgement expressed in the payout suggestion. This solves automatically point 2 as if the mediated payout suggestion is the same as the happy-path there is no avoid-penalty issue as no penalty was applied.
       		If seller confirms receipt in mediation the mediator can close anyway so there is only a bit of extra friction and delay due the communication but the dispute has to be closed anyway from the mediator. So I don't see that this creates any significant difference. If mediator has applied a penalty to the buyer the seller still gets his button activated (no penaly for seller - this is the only condition we check). So the seller has 2 options: accept mediated result and hope that buyer accept as well, or click confirm button and "forgive" buyer. The confirm button would stay active also after accept button has been clicked. So he can try mediated suggestion and before it goes to arbitration click the confirm button so we avoid arbitration cases.
