Node Installation

This guide shows how to install and run an Archway full node.

Running the Archway daemon#

How to install archwayd from source#

Make sure you have golang installed on your machine:

  • Install Go (version 1.16 or higher).
  • Ensure the Go environment variables are set properly on your system.

Get the source code:

git clone archway

Build and install:

make install

For full installation and configuration parameters, see the README.

How to run archwayd using Docker#

Make sure you have Docker installed on your machine. For Linux users, it's recommended to run the Docker daemon in Rootless Mode.

Pull the image from Docker Hub:

docker pull archwaynetwork/archwayd:latest

Each Archway network will eventually have a different version running. To connect your node to a network, you should use a tag with the corresponding network name. For example, to connect to the Constantine testnet:

docker pull archwaynetwork/archwayd:constantine

Make sure to always use the image tag that points to the network you want to connect.

By default, the Docker image runs the archwayd binary, so you should specify the arguments for archwayd right after the image name. For better usage, mount an external volume at /root/.archway to persist the daemon home path across different runs. For example, if you want to add a key:

docker run --rm -it \  -v ~/.archway:/root/.archway \  archwaynetwork/archwayd:latest \  keys add test-key

And then list all keys:

docker run --rm -it \  -v ~/.archway:/root/.archway \  archwaynetwork/archwayd:latest \  keys list

It's also important to notice that, when running a node in a network, you'll need to expose the container ports for external connectivity. The image exposes the following ports:

  • 1317: Rest server
  • 26656: Tendermint P2P
  • 26657: Tendermint RPC

To simplify using the Docker container, set an alias with the home path and the proper image tag (replacing <network-name>), like:

alias archwayd="docker run --rm -it -v ~/.archway:/root/.archway archwaynetwork/archwayd:<network-name>"

After setting this alias, you can use the other archwayd commands without typing the verbose Docker run command.

Initialize the Node#

Initialize the genesis.json file that is required to establish a network.

archwayd init my-node --chain-id my-chain

Prepare the Account and Keys#

Create a key to hold your account. After you run this command, you are prompted with a password dialogue. Enter a new password for your account.

archwayd keys add my-account

You see an output similar to the following:

- name: my-account  type: local  address: archway12ntzpk9fjt2x39pvll8ufma9tuhhnkh8g4zzc2  pubkey: archwaypub1addwnpepqfgjegqxxv9srfe359t93tu9l86tpkwwjk7w63xtpwq05wmlq9emjmxfmmv  mnemonic: ""  threshold: 0  pubkeys: []

**Important:** Write this mnemonic phrase in a safe place.It is the only way to recover your account if you ever forget your password.

Here you can see your account details and the mnemonic phrase that is very crucial to recover the account.

Starting the Node#

If you try to start the node, you get an error since at least one validator is required for your network to run.

archwayd start
Error: error during handshake: error on replay: validator set is nil in genesis and still empty after InitChain

To configure a validator node, see Validator Overview.
