ZERO 1.0.14

What is ZERO?

ZERO is is a fork of Zcash that in turn is a fork of Bitcoin.

This software is the ZERO client. It downloads and stores the entire history of ZERO 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.


Launch date: 2017-02-19

Comunity took over: 2017-12-05

Security Warnings

See important security warnings on the Security Information page.

ZERO is unfinished and highly experimental. 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.


Currently only Linux is officially supported. Requires at least 8GB RAM.

Install packages (needs to be done once only at start)

sudo apt-get install \
      build-essential pkg-config libc6-dev m4 g++-multilib \
      autoconf libtool ncurses-dev unzip git python python-zmq \
      zlib1g-dev wget bsdmainutils automake cmake

Obtain the ZERO software from GitHub

git clone
cd zero
git checkout master

Download cryptographic keys (needs to be done once only)


Build the source code to produce binary executables:

./zcutil/ --disable-rust -j$(nproc)

Create a ZERO configuration file

mkdir -p ~/.zero
echo "rpcuser=username" > ~/.zero/zero.conf
echo "rpcpassword=`head -c 32 /dev/urandom | base64`" >> ~/.zero/zero.conf
echo "rpcport=23800" >> ~/.zero/zero.conf

Seeder Nodes

As of 07/12/2017 the following seeder nodes work:

Check the thread for seeder node updates. The way you add seeder nodes to the config file:

echo "" >> ~/.zero/zero.conf

Enable CPU mining (optional)

echo 'gen=1' >> ~/.zero/zero.conf
echo "genproclimit=1" >> ~/.zero/zero.conf
echo 'equihashsolver=tromp' >> ~/.zero/zero.conf

When mining you're helping to strengthen the network and contributing to a social good. GPU mining is now possible, please see the announcement thread for more details.

Running & Using ZERO

After all the building steps you will have ZERO ready for use in folder zero/src. The two important binary executables are zcashd and zcash-cli.

Your wallet will be created (on first zcashd start) here: ~/.zero/ Please backup your wallet periodically and keep it safe.

The usage is currently the same as for ZCash. For more information see the ZCash User Guide.


For license information see the file COPYING.
