Guys/Gals, can we please please stop getting carried away with this shadow and cryptonote... Shadow is not based on cryptonote and does not function like cryptonote!
Thanks
Oops. Sorry.
smooth an I had a convo based on the assumption Shadow (ssv2) was based on cryptonote! He read the whitepaper and somehow was under the impression it was. How ddi this confusion begin?
Please tell us what it is if not based on cryptonote! Is it somehow an improvement?!
EDIT: Cryptonote 2.0 is cited in the references, altho I cannot see where the reference appears in the paper.
I have a question about shadow-to-shadow transactions.
0) I own 0 shadow.
1) Person A sends me 1 shadow.
2) I then myself 1 shadow. (not sure if this step is needed).
3) I send A some of the shadow back, say 0.9.
Question:
Is it possible for A using some offline techniques in the (far enough) future to tell this 0.9 shadow is mine with a high probability? Probably this depends on the number of transactions of the network and number of users. So if you answer this question feel free to go into this as well.
I know for instance that, as things are right now, with Monero this fails, i.e. person A can tell the money comes from me with a high probability.
Thank you.
We don't know exactly what is possible in the far future. It is not possible in either Monero or shadow to tell which addresses own which coins using the obvious direct inspection the way you can with a bitcoin-style coin. I assume by your comment about Monero you are referring to MRL-0001 which talks about some failures that can occur (allowing blockchain analysis to extract some information) if too-small ring sizes are used (and the same applies to shadow). The possibility of routine and frequent transfers between shadow and SDC provide another potential avenue of attack. Those are not the only potential weaknesses.
The current anonymity techniques we have now are steps in the right direction. No one has fully "solved" this yet.
