3. What are the stated benefits over ZeroCoin and ZKP-based approaches?
ZK is a new cryptographic system and as such, it is not mature enough, meaning many researchers and hackers will try to break it. So it’s possible that an exploit will emerge soon or later, making this a risky system to use.
Ring signatures are a much more mature system, they were designed in 2001, are simple and work well enough.
Another issue of ZKP: the RSA private key used to initiate the accumulator must be trusted to be destroyed by the generating party. If the ZK system is compromised, then an attacker can continuously spend coins that don’t exist using false proofs. Also, we can’t know if the syste has been yet compromised or not.
4. What are the stated benefits over CoinJoin-based approaches?
XMR’s ring signatures are far more secure and convenient than CoinJoin because:
- they mix outputs, not transactions;
- no need to wait for other senders to mix with;
- no restriction for the user to mix with other users sending the same amount;
- arbitrary amounts can be sent at any time without anyone else’s participation: this makes a timing analysis of the blockchain useless.
