darksend+ settings 1-8 ...>>>

[tungfa]

i still do not really understand why darksend + would have strings from 1-8 ! if 8 (obviously) is so much better and anonymous than 1 why even give an option of 1 ??
aren't we supposed to be anonymous all the way ? why give an option that gives "a little anonymity"if we know that "8 can get you all the way there" ???
say in the future some DRK user gets tracked by somebody (government or whatnot) and then DRK seems not that anonymous anymore, and our official DRK reply would be "yes he should have used setting 8 and not 1"
no point, i do not understand !

bellow is Evans reply from btctalk regarding the graph K Atlas put on his blog, that got me thinking

Does this diagram mean that with 1 round mixing for 2 users - coins are traceable (related to ours) with 50% chance?
So in simplified model, to make our coins 99% chance untraceable we need to mix it with at least 99 other Darkcoin's users? Is it correct?

If DS+ works as intended it means that there's an equal possibility that either party could own the prior money from the viewpoint of the blockchain after 1 round of mixing. Even then there's plausible deniability from future transactions. With more rounds of DS+ things get much harder to track, for example 8 rounds of DS+, there's 2^8 users with an equal likelihood of owning the prior money (256 possible users). With 3 participants per join, there's 3^8 users (6561).

DS+ just removes the blockchain as being used as proof that any user did anything with absolute certainty, which is our goal.

Has any crypto expert tried to track DS transactions at any rounds? Would love to see their reports on this thread.

The problem with higher number of rounds is that they take more time and transactions, so lower number are needed (even non DS funds when someone needs to send without waiting for anonymization.

and over time the whole coin supply will get more and more anonymised ... correct ... until all are on 8 one day ?

someday anon 1 1000 coins ... another anon 8 500 ... and so on ..?!

Not exactly, when you receive darkcoins that had been anonymized they are not anonymous in your wallet, the need to be anonymized again. Example (round numbers, not considering fees):

A sends 10 anonymized darkcoins to B.
B had a balance of 20 anonymized darkcoins before that payment and 1 non anonymized.
After the payment B has 20 anonymized darkcoins and 11 non anonymized.
If B has darksend enabled, the wallet will begin anonymizing again so in the end he will have 30 anonymized darkcoins and 1 non anonymized.

I have tested this and it works like that, but in the last step I had a problem because the new funds would not anonymize. I increased the number of rounds and then everything was anonymized to that new number of rounds. I'm reporting this now in case it is not a known issue.

my worry in this is just (i was pushing for anon always and only in highest setting) that at some point some DRK might be tracked due to ether not using the anon settings correctly or whatever else and then it will fire back at DRK in general as "oh their anon does not work"
know what i mean

Yeah, that could be an issue. I afraid there is no perfect solution that is both, fool proof to avoid mistakes from users, and at the same time gives them a lot of flexibility.
