How is this functionally different from everyone using "mixers" with Bitcoin?
- CiPHPerCoder 10y agoMixers just make graph traversal more expensive. They don't actually hide amounts.
- EthanHeilman 10y agoMixers often have limited anonymity sets, can sometimes be scams, are opt-in. We are seeing improvements in trustless mixers, but a fully anonymous currency is a very different beast. zCash offers a level of anonymity beyond anything we have seen (Monero hasn't activated CT yet). Systems with similar properties as zCash ([see auditable eCash](http://www.cs.tau.ac.il/~amnon/Papers/ST.crypto99.pdf) http://www.cs.tau.ac.il/~amnon/Papers/ST.crypto99.pdf)) have been discussed since the late 90's, today marks the first time to my knowledge one has been deployed in production. This is a big deal. I'll raise a glass to the zCash team. tl;dr zCash is a very impressive cryptographic achievement.
