We need separate functions for checking Sprout and Sapling nullifiers, because they are in separate domains and aren't guaranteed to be collision-resistant (otherwise there is a possibility of a nullifier collision, however remote, between Sprout and Sapling causing the spend of one to prevent the spend of the other).
Zcash 1.1.2
What is Zcash?
Zcash is an implementation of the "Zerocash" protocol. Based on Bitcoin's code, it intends to offer a far higher standard of privacy through a sophisticated zero-knowledge proving scheme that preserves confidentiality of transaction metadata. Technical details are available in our Protocol Specification.
This software is the Zcash client. It downloads and stores the entire history of Zcash transactions; depending on the speed of your computer and network connection, the synchronization process could take a day or more once the blockchain has reached a significant size.
Security Warnings
See important security warnings on the Security Information page.
Zcash is experimental and a work-in-progress. Use at your own risk.
Deprecation Policy
This release is considered deprecated 16 weeks after the release day. There is an automatic deprecation shutdown feature which will halt the node some time after this 16 week time period. The automatic feature is based on block height and can be explicitly disabled.
