Development Network

This guide walks through how to use fn dev to run and manage local blockchain instance[s] for software development and testing purposes. Alternatively, developers can also develop and test on Anvil Testnet.

1. Prerequisites

i) Install Golang

https://go.dev/doc/install

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

ii) Install Rust

https://rustup.rs/

If already installed, please update to 1.63 or newer

rustup update

iii) Install System Specific Dependencies

Ubuntu

sudo apt update && \
sudo apt upgrade -y && \
sudo apt install -y build-essential libleveldb-dev libssl-dev pkg-config clang libclang-dev librocksdb-dev

Mac

brew install openssl leveldb

2. Build Required Binaries

Findora blockchain can run on both MacOS or Linux. The commands below will build all required binaries to start a local Findora blockchain.

git clone -b v0.3.29-release https://github.com/FindoraNetwork/platform && \
cd platform && \
make build_release

Please make sure to add all below binaries to your $PATH. By default, they will be copied to ~/.cargo/bin/ which should already be in your $PATH.

• abcid: Findora core protocol.

• tendermint: Tendermint consensus engine.

• fn: The core development tool for working with a Findora blockchain.

3. Run and manage local development cluster[s]

Please use fn dev to run and manage your local clusters, check the documentation on github for a detailed user guide.
