Title: Is it possible to implement tumbling inside Bitcoin itself?
Post by: rotalumis on February 12, 2014, 11:41:27 AM
Consider if every time a new block is mined, the transaction inputs are sent to the outputs in such a way that each output receives a proportional amount from each input. Would this adequately tumble the coins, or would the increase in transactions bloat the blockchain?

Mandatory transaction mixing has been considered in the past and denied. CoinJoin obfuscates the transaction graph in a similar way though.

Any idea why it was denied? Or any links? Thanks.

Would we still be able to exhibit the source address, or am I misunderstanding Tumbling??

I think the point of tumbling is so nobody will know where the money went.

ah i see.  that sounds great.  i think it's kind of creepy how everyone's transaction record is visible.  should be encrypted and shit

Yeah, not exactly untraceable like the media point out. I think there are programs being worked on that are built on top of the blockchain for stuff like this though.
