The more the rounds, the deeper the anonymity. 2 rounds is already crazy good, 8 is like ultra-mode.
I don't think you need to give people the option for less than 8 rounds. People anon'ing their coins won't care if it takes a bit longer to go the additional rounds if it cuts the percentage down by a ton. After all, this is a privacy-centric coin at heart.
Thing is, you could pause darksend as it reach's 4 rounds, use coin control to select the coins with 4 rounds and send those.
Unless you made them undependable until they reach 8 rounds, which is bullshit anyway.
Users can asses the risk involved and make a sound judgment on how many rounds are appropriate.
I like the option of 1-8, infact why not 1-100?
1 is out of the question (3) and 100 is extreme (1.2676506e30). As for the rounds, you would remove the input factor leaving the start button. I see two viable pathways at this point, locks on the coins entering the round process to prevent them from being able to be spent (much like instantx locks coins) or disabling the ability to stop it once started. There is no reason why going 8 rounds has to take longer than a few hours assuming there are people darksending. I dream of a day when there is enough activity that 8 rounds would literally take 8 blocks.
If this is out of the question, simply putting a table underneath the option of rounds setting specifying the percentage might be enough to show people to go 8 rounds.
I'd go one further - 8 automatic and mandatory rounds. You can't spend until your coins have been anonymised. It would speed up mixing hugely.
I'd be for that but not sure how that would work with exchanges and pools.
however disabling the stop seems a little intrusive
), I'd create some kind of contingency whereupon the mining majority could somehow protect the masternode majority in some kind of symbiotic dependency.
