On a fresh Ubuntu installation, follow these commands.
Always ensure your server has the latest set of updates, due to performance and security considerations.
sudo apt-get update && sudo apt-get upgrade
It is best to create a specific ARK-related user, which can later own the required databases as well.
sudo adduser usernamesudo usermod -aG sudo username
Switch to the new user account and go to the base directory.
sudo su - usernamecd ~
We will use ARK installer script that will install all of the necessary dependencies, ARK Core onto your server and publish configuration files for it. To install essentials run this command.
bash <(curl -s https://raw.githubusercontent.com/ARKEcosystem/core/master/install.sh)
You will be asked to input your current users password for sudo privileges. Write or paste it and press enter to start installation process.
Process might take a while, don't interrupt it and wait for it to finish.
Once installation of dependencies and ARK Core is finished you will need to select on which network you wish to operate, since we are setting
mainnet node select it. This can be achieved by pressing
down arrow keys and confirming selection with
After you made your selection you will need to confirm by pressing
y and confirm with
Last step of the ARK Core essential configuration is to configure database parameters. You will be presented with a prompt:
Would you like to configure the database? [y/N]:
y and confirm with
You can input any custom database credentials you want to use or use the one provided below:
Enter the database username: arkEnter the database password: passwordEnter the database name: ark_mainnet
This will create PostgreSQL role and database to be used for storing blockchain data.
To start ARK relay process and with it synchronization process with ARK blockchain we need to start relay process with our integrated CLI:
If the process has started you will get a message:
Starting ark-relay... done
All CLI commands with description can be viewed at CLI Commands or by executing the
Now we want to see if the ARK relay process has started the synchronization process you can do that by running one of these two commands
If the process has started you will see a lot of messages like this (with actual data)
[YYYY-DD-MM hh:mm:ss][DEBUG]: Delegate <delegate name> (<public key>) allowed to forge block <#> 👍
Synchronization of the blockchain can take upwards of 10 hours so let it run, once its synronized
allowed to forge blockmessages will only pop-up every 8 seconds. A single round consists of 51 delegates each forging a single block.
Ensure you properly restart the node process when editing your
.envfile. Use the
--update-envflag, for example:pm2 restart all --update-env
Please note that API will be available when the node has synced with the network, which can take up to 15 hours depending on your network speed.
Now that the relay node has been configured, you should head over to the JSON-RPC Getting Started
or look at relevant Public API endpoints related to blockchain functionality to manage your wallets and transactions.
Please read the documentation pages for all of our ARK SDK clients and cryptography libraries (offered in many programming languages).
Also, read the API documentation.
