- Shadowcash has a two tiered network. One set of addresses is completely tra
nsparent. The other set is mixed. You can transfer between the two layers and keep the first set looking like unmixed transactions.
- Maidsafe will do instant and anonymous without history that can be tracked.
- Zcoin has indicated they may change to do mixing 100% of the time and still have a transparent blockchain. A much better solution to fungibility. This still might get the flag - but at least all Zcoins would be worth the same.
- Zcash will have thunder - Like lightning.
- Lightning will enable mixing and instant transactions. Looks like Litecoin may even be first with Bitcoin after. The mixing happens off blockchain so it shouldn't be detected by Coinfirm.
This illustrates a couple of significant points.
a. That every coin is going to support some kind of privacy or other and for that reason it's going to
fade into the background as a USP soon
b. Of the above, Dash is the ONLY (yes, only) case that doesn't do it by either diversifying the coin supply into transparent/opaque = resulting in destruction of fungibility, the very thing you're trying to optimise - or with recourse to an offchain solution
i.e. it inherits the bitcoin model and supports on-chain transparent fungibility. Thats the cash model going back 10,000 years and the reason Dash could support it is because its network has a pro-active protocol that takes a holistic approach to mixing, rather than doing it transaction by transaction. i.e. it's organic and its privacy improves over time because all of the coin supply is subject to mixing on an ongoing basis. Even if you don't use the "private" option in your particular wallet, someone before you did and someone after you will. History is constantly being scrubbed, day after day.
The other beauty of this approach is that it's not centralised in the protocol. Hypothetically de-anonymise one transaction ? So what. You need to do it all again just to find one more. On the other hand, protocol-based obfuscation is an all or nothing math-based tightrope. You solve one problem and you've cracked the whole chain.
