Regarding Mixing Service. Do we need such on-chain service that mixes coins with anonymity-reliability trade-off? 30% anonymity means 70% reliability to get all the coins back. Yes, it means that with 100% anonymity u could get 0% - 200% coins back.
can you elaborate on how the mixing service can work and why such high risks are involved?
the anonymity feature is quite important in my view.
That's the first approach we have, there might be other and better approaches.
You should only use it if you do so regularly and if you are aware of the risk.
You could mix 1.000 Nxt and you end up with 700.
The chance for that is really low tho, if you're familiar witch stochastics the more transactions you have going on, the closer you end up at + - 0%.
I find it hard to wrap my head around, but it's maths
