This guides shows how to run a Ganache-like personal local Findora blockchain in local environment for development and testing.
General Prerequisites​
Install Golang​
Tips for Linux (Ubuntu)​
# first command needs to be run as root, rest as your normal user
wget https://go.dev/dl/go1.18.3.linux-amd64.tar.gz
sudo su
rm -rf /usr/local/go && tar -C /usr/local -xzf go1.18.3.linux-amd64.tar.gz
# exit root now
exit
# add to path. For more permanent you should add this line to bottom of your ~/.profile
export PATH=$PATH:/usr/local/go/bin
# check go version
go version
Install Rust​
If already installed please update to 1.59 or newer
rustup update
Install System Specific Dependencies​
- Ubuntu
- Mac
sudo apt update && \
sudo apt upgrade -y && \
sudo apt install -y build-essential libleveldb-dev libssl-dev pkg-config clang libclang-dev librocksdb-dev
brew install openssl leveldb
Build Required Binaries​
Findora blockchain can run on both MacOS or Linux. Below command will build all required binaries to start a personal Findora blockchain.
git clone -b v0.3.19-release https://github.com/FindoraNetwork/platform && \
cd platform && \
make build_release
Please make sure to add all below 3 binaries to your $PATH. By default they will be copied to ~/.cargo/bin/ which should already be in your $PATH.
stt: The tool to initialize Findora blockchain.
abcid: Findora core protocol.
tendermint: Tendermint consensus engine.
Install Python3 and toml-cli​
Findora devnet tools are written in Python3 and uses toml-cli to manipulate configuration files. Install Python3 if you don't have one. Also install toml-cli using below command
pip3 install toml-cli
and then copy newly installed toml cli tool to /usr/local/bin to make it visiable
cp /Library/Python/3.x/site-packages/toml /usr/local/bin
