Introduction:
In this guide, we'll explore the concepts of a VPS as a Node Validator, and attempt to demonstrate how to set up a validator across various blockchains or networks, regardless of their specific characteristics.
Let's Start with the Basics:
Understanding a VPS:
A Virtual Private Server (VPS) is a web hosting option that grants users a dedicated, virtualized server environment, distinct from other users sharing the same physical server. This ensures superior control, flexibility, and security compared to shared hosting alternatives.
With VPS hosting, users can install their desired operating system, software, and applications, enjoying full root access to the server. This allows for the customization and optimization of the server environment, tailored to specific needs. Additionally, resources such as CPU, memory, and storage can be allocated and fine-tuned to accommodate fluctuating requirements, making VPS a perfect fit for websites or applications with variable resource demands.
In summary, VPS hosting balances the cost-effectiveness of shared hosting and the performance and control of dedicated hosting.
What is a Validator Node in a Blockchain?
In a blockchain network, validator nodes hold the responsibility of authenticating and validating transactions occurring on the network. These nodes execute intricate mathematical calculations to verify that transactions comply with the network's rules. Upon validation, transactions are appended to the blockchain ledger, making them visible to all participants.
Validator nodes are integral to upholding the security and integrity of a blockchain. By confirming the legitimacy of transactions and thwarting fraudulent activities, they help avert attacks or breaches that could jeopardize the network. In certain blockchain networks, validator nodes may also receive cryptocurrency or other incentives as rewards for their efforts.
Why Run a Validator Node?
Here are several reasons why running a validator node in a blockchain network could be beneficial:
Influence in network governance: Validator nodes significantly impact the rules and policies governing a blockchain network. By operating a validator node, you can actively participate in network operations and influence its future trajectory.
Potential rewards: Some blockchain networks offer rewards in the form of cryptocurrency or other incentives for validator nodes. These rewards can help cover the node operating costs and provide an extra income source.
Enhanced security: Validator nodes contribute to the security and integrity of a blockchain network by detecting and preventing fraudulent or malicious activities. Running a validator node aids in maintaining network reliability and security.
Increased decentralization: Blockchains aim for decentralization, ensuring that no single entity or organization exercises control over the network. Operating a validator node fosters greater decentralization, promoting increased transparency and accountability.
Chance to earn airdrops: Airdrops are a popular method for blockchain projects to distribute tokens or other rewards to users contributing to the network. By testing and evaluating the blockchain, you could qualify for these potentially valuable airdrops if the project succeeds.
Early access to new features: Participating in blockchain testing and evaluation allows you to be among the first to experience new features or capabilities not yet available to the broader public. This can offer a competitive edge or help you stay informed about industry trends.
Involvement in network development: Testing and evaluating the blockchain can provide essential feedback to developers and stakeholders about network functionality and potential improvements. By engaging in this process, you can influence the network's future and ensure it meets user needs.
With the fundamentals in place, let's outline a general guide to help set up a validator node for nearly any blockchain. Let's get started!
Review project documentation: First, determine the VPS requirements for running the Node by checking the project's documentation. Typically, this information is available in their documentation repository or GitHub – consult their website (example: https://docs.shardeum.org/).
Select a provider: Once the technical requirements are known, choose an online VPS hosting provider, like the one I use or any other you prefer. Sign up for an account and navigate to their control panel.
Create or order a VPS: Click "Create," "Add," or "Order" to launch a new VPS. Select an OS (e.g., Ubuntu, Debian), a data center location, and resources (CPU, RAM, storage). Confirm your choices to deploy the VPS and wait for activation (usually takes just a few minutes).
Note down VPS details: Log in to your VPS dashboard, verify if the VPS is activated, and record your VPS's IP address, username, and password for later use.
Download and use PuTTY: Now that the VPS is up and running and we have the server details, download PuTTY and open the software
6 - Setting Up PuTTY:
6.1. Paste your VPS's IP Address:
6.2. Configure connections:
Go to "Connections"
Enter 5 in the field beside "Seconds between keepalives"
Check "Enable TCP Keepalives (SO_KEEPALIVE option)" and click on "Open"
A new window will open:
Log in as "root"
Paste the password (from your VPS details).
Remember, to paste text in the PuTTY terminal, right-click and press "Enter" on your keyboard. After entering the password, you'll see a window like this:
7 - Set up the Validator Node:
7.1 - Refer to the project documentation for instructions on setting up the node software and dependencies. Typically, you'll need to enter a few lines of code (copy and right-click into PuTTY) and run them.
7.2 - Access the Dashboard and Start the Node:
The dashboard link is usually: https://localhost:8080/. Replace "localhost" with your VPS IP address (e.g., if your VPS IP is 92.155.5.122, your dashboard link is https://92.155.5.122:8080)
Return to the documentation or join their Discord to find out where to get the tokens (for a testnet validator node, you'll need testnet tokens) and how to start the node and stake the tokens.
7.3 - Operate Your Testnet Validator:
8 - Smooth Sailing:
With your testnet validator up and running and the minimum required tokens staked, frequently check for errors, report them to the dev team, and start collecting rewards for your contributions!
BONUS: Here is a thread compilation to guide you on setting up testnet validators for various blockchains, with all credit going to the thread authors.
