ZERO - Latest Release

•LAUNCH DATE: 2017-02-19

GENESIS BLOCK - 19th Feb 2017 11:26:40 - 068cbb5db6bc11be5b93479ea4df41fa7e012e92ca8603c315f9b1a2202205c6

What is ZERO?

ZERO is a revolutionary cryptocurrency and transaction platform based on Zcash.

ZERO offers total payment confidentiality, while still maintaining a decentralised network using a public blockchain.

ZERO combines Bitcoin’s security with Zcash’s anonymity and privacy.

ZERO stands out from the competition as a fully working product that has already implemented a set of special features not found in any other cryptocurrency.

Our main focus as a team and community is to remain as transparent as we can possibly be and to maintain an interactive relationship with everyone involved. We are fully open about the project, listening to all suggestions from investors, miners and supporters.

This software is the ZERO node. It downloads and stores the entire history of ZERO's transactions, about 2GB at this point. Depending on the speed of your computer and network connection, the synchronization process could take several hours.

Zero uses an alternative set of parameters for the Equihash algorithm, which require a GPU with 8GB of RAM. Zero is often one of the most profitable cryptocurrencies to mine.

Is Zero Legal?

Zero is legal in most jurisdictions in the world but there are a small number of nation states that have banned its use, such as Ecuador. Wikipedia has a great guide on how Crypto is treated in all countries around the world and explains regulatory policies surrounding it. Regulations vary from one border to the next so you should always research your location’s laws before participating in the network.

Why Trust Zero?

Zero is a network operating by the three fundamental principles of technological freedom: Decentralization, Open Source code and true Peer-to-Peer technology. With Privacy being a fundamental human right. Zero’s trust is based on the subjective valuations of human faith in mathematical algorithms, encryption and numbers. With the three pillars of technological principles Zero’s Blockchain is a peer-reviewed system of integrity.

Zero has a low emission and the inflation degrades over time quickly. Stable supply is 3888 ZER, after first halfing.

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

📣 Announcements

🔒 Security Warnings

See important security warnings on the Security Information page.

Zero is experimental and a work in progress. Use it at your own risk.

📒 Deprecation Policy

Disabledeprecation flag has been removed. Old nodes will automatically be shut down and must be upgraded upon reaching the deprecation block height, which will occur approximately 52 weeks (6/23/2022) from the release of v3.3.0.

🔧 Building

Currently only Linux build is officially supported. 8GB RAM is recommended.

Install packages (needs to be done only once)

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 curl

Obtain the ZERO software from GitHub

git clone
cd zero
git checkout master

Download cryptographic keys (needs to be done only once)


Build the source code to produce binary executables:

./zcutil/ -j$(nproc)

On a typical laptop -j2 works fine, while retaining some UI interactivity

Create a Zero configuration file

mkdir -p ~/.zero
echo "server=1" > ~/.zero/zero.conf

To use the full node RPC interface

echo "rpcuser=<YOUR_USER_NAME>" > ~/.zero/zero.conf
echo "rpcpassword=`head -c 32 /dev/urandom | base64`" >> ~/.zero/zero.conf
echo "rpcport=23801" >> ~/.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

🔩 Running Zero

After successfully building, the Zero binaries are stored in ./src. The two important binaries are zerod and zero-cli. To run zerod in the background

./zerod --daemon

To see command line options (also available in zero.conf file)

./zerod -?

Your wallet will be created (on first zerod run) in: ~/.zero/ Please, backup your wallet often and keep it safe and secret.

The usage is currently very similar to Zcash. For more information see the Zcash User Guide.
