Running Testnet

Install Required Tools #

Now we are going to install Go.
First, install the required build tools:

# Update package lists and upgrade installed packages
(validator)$ apt upgrade -y

# Install software-properties-common
(validator)$ apt install -y software-properties-common

# Add the Go programming language repository
(validator)$ add-apt-repository -y ppa:longsleep/golang-backports

# Update package lists after adding the repository
(validator)$ apt update

Install Go #

# Install go
(validator)$ apt install -y golang-go

EVM-compatible chain secured by the Forest consensus algorithm. With NCOG Earth Chain, you can experience the fastest blockchain transactions.

Building the source #

Building ncogearthchain requires both a Go (version 1.14 or later) and a C compiler. You can install them using your favourite package manager. Once the dependencies are installed, run

make ncogearthchain

The build output is build/ncogearthchain executable.

Running Testnet #

The network is specified only by its genesis file, so running a testnet node is equivalent to using a testnet genesis file instead of a mainnet genesis file:

$ ncogearthchain --genesis /path/to/testnet.g # launch node

It may be convenient to use a separate datadir for your testnet node to avoid collisions with other networks:

$ ncogearthchain --genesis /path/to/testnet.g --datadir /path/to/datadir # launch node
$ ncogearthchain --datadir /path/to/datadir account new # create new account
$ ncogearthchain --datadir /path/to/datadir attach # attach to IPC

Testing
Forest has extensive unit-testing. Use the Go tool to run tests:

go test ./...

If everything goes well, it should output something along these lines:

Also it is tested with fuzzing.
