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.
I can't. I don't know the algo. It costs 1M NXT.
Ok, I have an algo, too and will send it to you for only 900.000 NXT. It has 99,99% anoymity. And that is PER NXT! Deal?
Seriously, don't pay upfront. Make a bounty and set a date, just like you did with javascript encryption. Winner is whatever gets implemented in NXT.
