Development Network
This guide walks through how to deploy a local blockchain instance for software development and testing purposes. Alternatively, developers can also develop and test on Anvil Testnet.

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

If already installed, please update to 1.59 or newer
rustup update

Ubuntu
Second Tab
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​

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 v0.3.19-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.

Findora devnet tools are written in Python3 and use toml-cli to manipulate configuration files. Install Python3 if not already installed. Also, install toml-cli using the command below:
pip3 install toml-cli
and then copy newly installed toml cli tool to /usr/local/bin to make it visible
cp /Library/Python/3.x/site-packages/toml /usr/local/bin

Inside your platform directory, execute make devnet in the terminal.

The local blockchain can be stopped and restarted anytime during development and tests.
  • Stop Blockchain: ./tools/devnet/stopnodes.sh
  • Restart Blockchain: ./tools/devnet/startnodes.sh
  • Start Over: make devnet again.

  • Problem 1
    • Error Message:
      • make build_release fails with go:linkname must refer to declared function or variable
  • Solution
    • Update your golang.org/x/sys
      # go to platform/tools/tendermint run following to update
      go get -u golang.org/x/sys
  • Problem 2
    • .findora file is missing
  • Solution
    • manually add .findora to your home directory (i.e. directory ~)
