I'd like to correct a couple of misunderstandings regarding Darkcoin in your otherwise outstanding PR material.

First, you say that DarkSend is a mixing service. It's not a service, it's a decentralized offchain mixing implementation.

Secondly, you say that with blockchain analysis software, it is easy to deanonymize transactions that have been mixed using these services (which include DarkSend). But because DarkSend mixing is done offchain, it actually cannot be deanonymized by analyzing the blockchain. Whereas with enough computing power (quantum computers, or unexpected advances in math), onchain anonymized blockchains (zerocoin, cryptonote, zerocash) can be deanonymized. In that sense DarkSend is future proof.

Hi, I'm not trying to start any flamewar here or disparage DRK in any way (I am a prominent member of the darkcoin community after all). But I need to respond to this post in the interest of defending the facts. It is absolutely 100% incorrect to say that Darksend mixing occurs offchain. It happens 100% onchain and I have spent many hours analyzing the Darksend transactions on the blockchain during DRKs early development and communicating with Evan about how to improve the process. I think DRK does a good job of anonymizing transactions, but they are still onchain and they could potentially be de-anonymized via taint analysis under certain circumstances - read Kristov's analysis for further details. DRK is an excellent coin IMO, but your statement above is inaccurate. The best way to describe DRKs mixing is "a decentralized multi-step mixing service".

Absolutely no flamewar wanted or needed - and I'm happy being proven wrong, that's when learning happens the best.

However, we don't have an established terminology yet I guess, so imo what offchain vs onchain anonymization means is:

offchain anonymization = correlation between inputs and outputs does not exist in the blockchain
onchain anonymization = correlation between inputs and outputs does exist in the blockchain, but is hidden by using cryptography (method of hiding could be ring signatures, or zerocoin)

I noticed that off chain tec which depends on gateway transfer had been developed by some devs, it is not a mystery,and in fact the gateway technology can also be analyzed,everything is mathematics,so I prefer to trust Zerocoin which holds zero-knowledge proof .
