Running Nodes on Testnets

Running Nodes on Blockchain Testnets

Every blockchain project undergoes rigorous testing before facing the public eye. The process starts with internal tests by the development team, followed by open beta phases where anyone (or a selected group) can participate. This feedback helps identify and fix bugs, ensuring a smooth launch. However, for most projects, testing comes with the responsibility of setting up and maintaining nodes - which involves software updates, version upgrades, error troubleshooting, and restarts.
 
What is a Node and Why Do We Need It?
A node, in basic terms, functions as a server, a computer located remotely or not too far away, equipped with specialized software. After leasing and setting up a remote server, a node is established, facilitating communication with other network members and managing the storage, transmission, and reception of transaction information.
 
Picture a towering skyscraper, its strength dependent on a hidden network of steel beams. Nodes are the equivalent in the blockchain world, forming the invisible backbone that underpins every project. We are the node technicians, meticulously ensuring their stability and functionality, one at a time, laying the groundwork for a future powered by decentralized networks.
 
The essential goal of decentralization is to enhance network security significantly. Every transaction undergoes confirmation by multiple autonomous nodes, preventing any possibility of falsifying data.
 
The cost of running a node on mainnet of a blockchain, such as Solana mainnet, is pretty high since you actually need real tokens to run the node. However, running a node on a testnet is basically free since there are faucets where you can get coins or tokens for free. You just have to pay for the server you’re gonna run the node on, which I’ll be mentioning shortly.
 
Testnet Rewards
As a gesture of appreciation for the efforts and data contributed to the development team, testnet participants may receive coins on mainnet. It is important to note that there are two main types of testnets: those with rewards(called incentivized) and those without.

It's crucial to acknowledge that not all incentivized testnets fulfill their payment promises. Similarly, projects that don't explicitly mention rewards may still express gratitude by offering participants a certain amount of coins.
 
Frequently, the coin or token associated with the product being tested is not yet traded on exchanges or decentralized exchanges, rendering it without a market price. Occasionally, project teams may continue testing their product even after listing, rewarding participants with tokens that now have an established value.
 
Several scenarios need to be considered when deciding to run a testnet node:
 

• The project may not pay anything, even if a reward was pledged.
• The project may provide compensation, even without a prior commitment.
• The project may compensate in tokens that initially hold no value.
• The project may reward participants with tokens that are already actively traded and have a tangible market price.

 
Costs of Testnet Participation
To establish a node, beyond the enthusiasm and available time, you must possess the necessary hardware to support it.
 
If you have a fondness for your personal computer, it's unlikely you'd consider transforming it into a node. Instead, a server, essentially a remote "computer," is required—one that operates inconspicuously in a distant location without causing concern. This is called a Virtual Private Server - VPS.
 
The expense of leasing such a server is contingent upon the hardware specifications, with the specific requirements varying for each node based on the project's needs.
 
Typically, the cost of renting a single server for a node ranges from $15 to $50 per month. However, certain projects may demand more advanced equipment, such as graphics cards, elevating the monthly server rental cost to the range of $200–$300.

How Can You Run a Node?
You can follow these steps to run your own node:
- Rent a VPS from one of the providers. (I personally use Hetzner to run my nodes)
- Select the testnet you want to run the node for
- Set up your VPS to run the node
