The first thing to notice is that the PRF for r cannot be keyed by sk without revealing it to the prover. Second, there is no longer a need for h Sig-style ephemeral public keys. There are two benefits to this: first, the zk-SNARK prover does not have spend authority, which allows us to achieve delegated proving for hardware wallets, mobile devices, businesses, etc. As far as we're aware, this is compatible with standard threshold signature schemes. Outside of the zk-SNARK, the person in possession of sk can also sign using a Schnorr signature.

The first intuition is to treat nullifiers as randomized public keys, i.e., (g sk) r where r is the output of a PRF, and g is the generator of the fast ECC curve group from #2230. This is a casual overview of the payment construction that Matthew, Ian and I have been playing with. Licenseįor license information see the file COPYING. See the Debian / Ubuntu build for detailed instructions. zcutil/build.sh -j$(nproc)Ĭurrently, Zcash is only officially supported on Debian and Ubuntu.

More technical details are available in our Protocol Specification. Based on Bitcoin's code, Zcash intends to offer a far higher standard of privacy through a sophisticated zero-knowledge proving scheme that preserves confidentiality of transaction metadata. Zcash is an implementation of the "Zerocash" protocol.
