First off, has there been enough time to assess if ShadowCash project has a working Zero Knowledge solution?

Secondly, does the Monero project of Darkcoin project have a Zero Knowledge solution?

I'd like to compare anonymous transactions between the three projects being discussed here; XMR, DRK & Shadow. Could somebody post transaction IDs for each project showing an anonymous trade? I'd like to compare apples to apples when it comes to linkability and traceability. Ignoring codebase and proof differences between them for now.

If there are other working ZK solutions in projects I haven't mentioned that should be part of this comparison please add an anonymous transaction from them as well.

1 good example from each blockchain would be appreciated.

Thanks.
