What if an alternate currency had a large reserve of coins which would be used for a giant coin mixing service for that currency ?
For example opencoin and their 80 billion spare coins could accept "tainted" ripples and swap them out for fresh coins.
Its probably not going to happen for obvious reasons
You should try Tenebrix:
https://bitcointalksearch.org/topic/announce-tenebrix-a-cpu-friendly-gpu-hostile-cryptocurrency-45667Q: I heard you premined, you bad bad person...
A: Well yes, I premined 7 million coins. Why so many - well, to be completely blunt and honest, I got a bit tired of a discussion of how much should one premine that I had going on and used the premine value from GeistGeld. Perhaps not the wisest decision, but worry not though - I will use 2 millions do fuel verry slow (no more than 4 TBX per user, may get less if their price rises) faucets with strong user ID (Google Acc + captchas), and about 1.5 mils are set aside to help recruit developers and sustain support for no less than 6 years (you gotta agree that it is a looong road and a lot of money-gulping things can happen)
I will use the rest to start a unique transaction-anonymization service, using them as a buffer of sorts (old TBX + fee enters, crispy TBX from reserve exit in a certain randomized manner. In the end, I keep only the "fees" and the "old TBX" that entered the service are retained to form a new buffer as old one shrinks. Thus, the amount of TBX destined for buffer remains static forever, and never ever enters circulation, sequestered as a "transaction mixing service buffer" forever. I think we can all agree that stronger transaction mixing is a good thing and a benefit to community Smiley )
Should be done "real soon now"
