ZERC is a fork of ZeroCurrency and Zcash. Zcash is a fork of Bitcoin that adds shielded transaction via zk-SNARKs.

This software is the ZERO Classic node. It downloads and stores the entire history of ZERO Classic transactions, about 1GB at this point. Depending on the speed of your computer and network connection, the synchronization process could take several hours.

Announcements

On September 15th, the old ZERO will fork to add block halving and dev fees. This means that a % of the Zero block reward, will go straight into the devs wallets. We've dediced to NOT SUPPORT THIS UPDATE and continue maintaining the old fashioned Zero like it should be. Free, open source, without any fee. This is why ZERO Classic (ZERC) is born.

What should I do if I already own some coins?

Zero will then have two chains:

• MAIN CHAIN --> the one for users who will update their wallet
• SIDE CHAIN --> the one who decided to keep their wallet as it was

Coins existing on the initial chain, before 15th of September, will continue to exists in both chains. Then, every fork will continue on his own. Even your receiving adresses.

Security Warnings

See important security warnings on the Security Information page.

ZERO Classic is unfinished and highly experimental. Use at your own risk.

Deprecation Policy

This release is considered deprecated 26 weeks after the release day. There is an automatic deprecation shutdown feature which will halt the node some time after this 26 week time period. The automatic feature is based on block height and can be explicitly disabled.

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

Download cryptographic keys (needs to be done only once)

./zcutil/fetch-params.sh

Obtain the ZERO Classic software from GitHub

git clone https://github.com/LEAD-Anoy74/ZeroClassic/
cd ZeroClassic
git checkout master

Build the source code to produce binary executables:

cd ZeroClassic
chmod +x zcutil/build.sh depends/config.guess depends/config.sub autogen.sh share/genbuild.sh src/leveldb/build_detect_platform
./zcutil/build.sh --disable-rust -j$(nproc)

On a typical laptop -j3 works fine, while retaining some UI interactivity

./zcutil/build.sh --disable-rust -j3

Create a ZERO Classic configuration file

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

Seeder Nodes

As of 05/12/2018 the following seeder nodes are up and run a recent Linux version:

addnode=163.172.49.214
addnode=
addnode=

Enable CPU mining (optional)

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

A sample of the current zero.conf

./contrib/zero.conf

A sample demonstrating a large number of command line options

./contrib/debian/examples/zero.conf

Running & Using ZERO Classic

After a successful build ZERO Classic binaries are in ./src. The two important binaries are zcashd and zcash-cli.

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

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