Zerocash / Zerocoin weaknesses
Here is the analysis of Anonymint on the weaknesses of Zerocash/Zerocoin. For those of you who are new and dont know him. Anonymint is a "world class programmer who knows his sh*t" and even though he is not part of the dev team have been instrumental to the discussions leading to the development of the latest Darksend. This is worth reading.
Anonymint also say that Bitcoin itself has a lot of flaws in design and never success. And all other coins are based on Bitcoin structure. So if we listen to him we should abandon all cryptocurrencies ?
I agree that Zerocash is very new and using untested technology. Zerocash's devoloper, Matthew Green, even said in a presentation that people should not put too much faith and money into Zerocash's model. However these is a advantage that Zero-Knowlegde Proof can provide is unmatched level of privacy. If you view the slides of Zerocash, you can see that it can hide transactions, balance, of a particular address.
