How long did it take for the CN clones to be deemed "tested" by your standard?
1.post an SDC>SDT tx and I'll guess the value sent looking at inputs/ouputs on chain. I got pretty good at it back in the day
2. Burn 200SDC for SDT and then burn the SDT for 200SDC and I'll tell you the address of the newly created SDC
From the roadmap and what the team said. Please link Ryno's comment, or the BitBay whitepaper
Is it a joke or is it really possible to deanonymize ShadowSend transactions?
Lol no its not possible. I'll play CH's little game as soon as I get all my wallets running and synced up.
BASICS:
1. Shadow uses 2 tokens, one like BTC (SDC) and the other like Crytonote (SDT).
2. SDC>SDT: All the currency is minted as SDC and the user can at will burn SDC to create an SDT token by making an SDC>SDT TX. This is NOT fully anonymous.
3. SDT>SDT: Once a user has created SDT (Cryptonote) tokens he can send an SDT>SDT TX which (at least theoretically since no code audit has been performed) is like a Monero (Cryptonote) TX and anonymises the sender and receiver and amount.
4. SDT>SDC send is there to burn your SDT tokens and create SDC: Why would you even do this? Only SDC stakes and there is no trading of SDT tokens. When this TX is sent the SDC are created in a newly generated address. This is NOT fully anonymous.
PROBLEMS:
1. Whilst SDT tokens might be anonymous, SDC tokens are not and SDC tokens compromises the anonymity of the SDT tokens. Since we now the total supply of SDC at any given time, blockchain analysis tells us how many SDT are in circulation at any given time. When the SDC supply drops we know the SDT supply has increased and vice versa. Studying the balances of SDC addresses on the blockchain as these fluctuations in SDC/SDT supply occur leaks information.
2. If a user burns a specific amount of SDC (e.g. 666.666) to create SDT and then the recipient burns them straight back to SDC minus tx fees (e.g. 666.566), blockchain analysis makes a clear connection. The fluctuations of SDC balances on the blockchain reveal information about SDT usage.
3. As a result of a user should create a larger pool of SDT which he occasionally spends from to increase his anonymity. Therefor a user's behaviour can increase or decrease the efficacy of the system's anonymity.
4. The system is far too convoluted for an average user and less anonymous than a crytonote coin.
CONCLUSION:
From the perspective of anonymity the only useful TX is an SDT>SDT TX which acts as a cryptonote/Monero TX. The SDC tokens which are destroyed to create SDT compromise the anonymity of the system and user since SDC>SDT and SDT>SDC leak information. As a clever friend pointed out, why even have two tokens? I believe Monero and CN coins to be more anonymous than ShadowCash. The lack of peer review, thin whitepaper and lack of proper discussion for ShadowSend strengthens this view.
