1.) How do you know the key was destroyed? What if they faked it?
Are you thinking of anoncoin? AFAIK cryptonote doesn't have that problem, but I could be wrong.
"Other issues include the RSA private key used to initiate the accumulator, which must be trusted to be destroyed by the generating party"
https://bitcointalk.org/index.php?topic=583449.0They're talking about zerocoin there, right? Section topic is "How does this compare to other anonymous solutions?"
Correct, that refers to ZKP-based approaches. CryptoNote uses ring signatures so it doesn't require any such thing.
Yeah, I was confusing the two. Actually, awhile back Anonymint was suggesting we use ring signatures for DarkSend. I'll do some research, maybe that can be a V2 feature.
