^FOLLOW-UP question:

1. if the user has a pool of shadow (which are invisible on the blockchain, yes?)
2. some of the pooled shadow are sent to a newly generated recipient stealth address,  
3. when/if they are converted back to SDC by the recipient stealth address they would be completely anonymous?

"Competely anonymous" is not really a well defined term, especially when considering indirect inferences from timing factors and such.

Clearly the more you (and everyone else) use shadow (and using higher mix factors when you do) the less information you are leaking to potential blockchain analysis.

The scenario you describe is clearly better than frequent conversions back and forth, but not as good as everything being done with shadow exclusively. In order for that to happen every merchant, exchange, etc. needs to support it directly, and you also need to be willing to except the higher inherent costs of transactions.



Are shadow tokens invisible on the blockchain/richlist? Getting everybody to accept shadow seems possible, partuclarly since that would actually take advantage of this coins features.

They are not linkable and spending isn't provable, so there is generally no way to create a meaningful richest.

The concept of an address "balance" isn't meaningful the way it is with a bitcoin-style coin.

Given that shadow uses the well-regarded cryptonote techniques and SDC uses bitcoin-style coins which are well known to be vulnerable to a lot of analysis/tracing, it is pretty obvious that more you use the former and the less you use the latter, the more actual anonymity will be achieved.

You can't stake shadow though. I'm not sure if that's something that matters a lot to folks here. The Louisd’or project has recently developed a PoS method that works with cryptonote and could probably be adapted here, so longer term that might be possible.
