I love Darksend but you have to realize it will be replaced once someone starts a zero knowledge proof coin.

While I've been working on DarkSend I've been thinking about this alot. You know what the problem is with a zero knowledge proof? There's a secret key that will be attacked by governments and it will eventually be cracked. That will make every transaction that ever happened in that blockchain cleartext and allow every future transaction to also be viewed as cleartext. I'm going to venture to say the government is working on quantum computers and such crypto can be solved with shor's algorithm. When they do, they're not going to tell anyone. So it's a giant honeypot.

DarkSend is immune to such attacks, all involved crypto functions could be cracked and the mixing is still done off blockchain by the masternodes. Off blockchain means that the information is lost and that's the only way to secure it, you can't do it with cryptography.

Long time no see.

Does anybody know if Evan feels the same now?
This "secret key" problem as he describes?

Evan?

I don't know much about Evan's feelings Grin

, but since his statement is based on facts and mathematics his statement will be the same.

Maybe today he'll go as far as I do and changes the statement to "anything with a secret master key is fucked-up by design, but no one will tell you because the people in charge (governments et al) like it that way".

(okay, he will use the word "broken" instead of "fucked-up".)

Six months is a long time in crypto. Perhaps there have been developments in ZK that have led Evan to change his feelings?
For example Evan's above comment speaks about decrypting every ZK transaction by cracking ONE secret master key. The use of a multiple key architecture would presumably take care of this assuming such a thing were do-able. Perhaps off-blockchain tech exists for ZK?

I'm no expert, but I do know enough time has elapsed for the "landscape" to have changed.

I hold DRK and SDC (ShadowCash). We do know that Evan approached SDC for a merger and we know SDC are doing ZK work. Evan spoke of his respect for ryno's coding abilities but was he also interested in the ZK research of the Shadow team?

I'm all about the ANon and quest for the best.

BTW (hypothetical) What happens if one group runs a good chunk of masternodes, say 51%. Would they have any advantage in breaking darksend anon (like running lots of tor nodes breaks tor anon)?

thx
