"Zerocash can be deployed atop any ledger (even one maintained by a central bank). Here, we briefly detail integration with the Bitcoin protocol."
"Zerocash breaks compatibility with the Bitcoin network. While Zerocash could be integrated into Bitcoin (the actual currency and its supporting software) via a “flag day” where a super-majority of Bitcoin miners simultaneously adopt the new software, we neither expect nor advise such integration in the near future and suggest using Zerocash in a separate altcoin."
"Integrating Zerocash into Bitcoin consists of adding a new transaction type, Zerocash transactions, and modifying the protocol and software to invoke Zerocash’s DAP interface to create and verify these transactions. There are at least two possible approaches to this integration. The first approach replaces all bitcoins with zerocoins, making all transactions anonymous at the cost of losing any additional Bitcoin functionality provided by, e.g., the Bitcoin scripting language (see Section 6.1).
The second approach maintains this functionality, adding a parallel Zerocash currency, zerocoin, which can be converted to and from bitcoin at a one-to-one rate "
