Installing from source

Installing pzec from source requires rustc and cargo.

Minimal supported version is rustc 1.23.0 (766bd11c8 2018-01-01)

Install rustc and cargo

Both rustc and cargo are a part of rust tool-chain.

An easy way to install the stable binaries for Linux and Mac is to run this in your shell:

curl https://sh.rustup.rs -sSf | sh

Windows binaries can be downloaded from rust-lang website.

Install C and C++ compilers

You will need the cc and gcc compilers to build some of the dependencies.

On macOS

build-essential is a Debian package. On macOS you will need to make sure you have Xcode installed. If you already have Homebrew installed, you probably also already have the Xcode tools installed as well. If not, you can run the command below:

xcode-select --install

On Linux

sudo apt-get update
sudo apt-get install build-essential

Clone and build pzec

Now let's clone pzec and enter it's directory:

git clone https://github.com/paritytech/parity-zcash
cd parity-zcash

# builds pzec in release mode
cargo build -p pzec --release

pzec is now available at ./target/release/pzec.

Installing the snap

In any of the supported Linux distros:

sudo snap install parity-zcash --edge

Running tests

pzec has internal unit tests and it conforms to external integration tests.

Running unit tests

Assuming that repository is already cloned, we can run unit tests with this command:

cargo test --all

Going online

By default parity connects to Zcash seednodes. Full list is here.

To start syncing the main network, just start the client without any arguments:

./target/release/pzec

To start syncing the testnet:

./target/release/pzec --testnet

To not print any syncing progress add --quiet flag:

./target/release/pzec --quiet

Importing zcashd database

It it is possible to import existing zcashd database:

# where $ZCASH_DB is path to your zcashd database. By default:
# on macOS: "/Users/user/Library/Application Support/Zcash"
# on Linux: "~/.zcash"
./target/release/pzec import "$ZCASH_DB/blocks"

By default, import verifies the imported blocks. You can disable this, by adding the --verification-level=none option.

./target/release/pzec --verification-level=none import "$ZCASH_DB/blocks"

Command line interface

Full list of CLI options, which is available under pzec --help: see here

Logging

This is a section only for developers and power users.

You can enable detailed client logging by setting the environment variable RUST_LOG, e.g.,

RUST_LOG=verification=info ./target/release/pzec

pzec started with this environment variable will print all logs coming from verification module with verbosity info or higher. Available log levels are:

• error
• warn
• info
• debug
• trace

It's also possible to start logging from multiple modules in the same time:

RUST_LOG=sync=trace,p2p=trace,verification=trace,db=trace ./target/release/pzec

Internal documentation

Once released, pzec documentation will be available here. Meanwhile it's only possible to build it locally:

cd parity-zcash
./tools/doc.sh
open target/doc/pzec/index.html
