In these docs I will explore crypto currencies, how they work, specifically the decentralized manner of it's implementation, how web 3.0 fits into all of that and how to mine different altcoins and what can be profeitable with little investment

The first two currenies I'm going to try mine is ZCASH and

# ZCASH Crypto Mining

Official Docs

# Install ZCASH Wallet

Enter the following command in your terminal

sudo yum install \
autoconf libtool unzip git python \
wget curl  automake gcc gcc-c++ patch \
glibc-static libstdc++-static

And then

sudo yum install centos-release-scl-rh
sudo yum install devtoolset-3-gcc devtoolset-3-gcc-c++
sudo update-alternatives --install /usr/bin/gcc-4.9 gcc-4.9 /opt/rh/devtoolset-3/root/usr/bin/gcc 10
sudo update-alternatives --install /usr/bin/g++-4.9 g++-4.9 /opt/rh/devtoolset-3/root/usr/bin/g++ 10
scl enable devtoolset-3 bash

All of that was just some prerequisites before you actually have to build it from source

Clone the following repo: https://github.com/zcash/zcash.git

 git clone https://github.com/zcash/zcash.git
 cd zcash/
 git checkout v5.0.0
 ./zcutil/fetch-params.sh

This above includes fetching zcash parameters, which are numerical dependencies for Zcash a result of the crypto inside. They are around 760 MB in size, so it will take time to download them.

Now to build from source

./zcutil/clean.sh
./zcutil/build.sh -j$(nproc)
