Participation in various testnets is a very amusing activity that various crypto projects carry out and sometimes reward their participants. This may be of interest to both a beginner who does not want to invest a large amount of savings in the cryptocurrency market, and more "old" market participants who are always happy to test their strength in an interesting project with potential rewards.

Many people think that such activities are very simple, but alas, you often have to invest a lot of time and effort to receive any rewards from projects.

Firstly you need to understand the essence of such words as "testnet" and "node", and only after that consider the possibilities of making money on such activities.



The development of serious infrastructure projects is a very long process, where every shortcoming can lead to serious consequences, for example, network hаcks. That is why developers at the first stages of project testing use a particular environment that, without any risks, allows you to eliminate bugs, check all the functions and developments - a testnet or a test network.

A testnet is a kind of "sandbox", almost identical to the main network, which allows developers to test the necessary functionality without using real cryptocurrency and without any risks for the mainnet.

Mainnet or the main network is a ready-to-use network in which transactions with real cryptocurrency take place.

Currently, there are a big number of testnets, ranging from technical ones, where participants are invited to help the project write some kind of program or script for a possible reward, ending with interface testing, when it is necessary to look for possible bugs on some platform, make transactions using test tokens and etc.

By awards, test networks are divided into 2 types:

    Incentivized - this is when the project provides a reward for participants. These can be both prize places in the leaderboard, and rewards for every participant, for example, project tokens, allocation on the sale, access to early versions of the application, etc.

    Not stimulating (Non-Incentivised) - this is when the project does not promise anything, but rarely, but there are times when projects, promising nothing, still thank their participants.


Usually, all interactions in the test network occur much faster than in the main one, which allows the team to concentrate on the main thing - developing and implementing innovations and stabilizing the network.

It is important to note that recently, for many projects, conducting a testnet is also a good marketing campaign.

Such activity carries a large number of advantages both for the developers of the project mentioned earlier and for the participants - this is a good opportunity to earn money.



A node of a network is a regular computer on which a certain program is running and constantly running.

⠀Each node is connected to other nodes (computers) called peers, which allows you to come to a consensus - a particular mechanism that checks information about the "correctness" of transactions in the network. In other words, so that the cryptocurrency involved in the transaction is spent only once.


There are several types of nodes:

    A full node is a regular computer on which a certain program is running and constantly running, fully synchronized with the network. It also stores the full history of the network, starting from the moment of creation.

    A lightweight node is a regular computer on which a certain program is running and constantly running, but without the need to store the entire history of the network, but only the data that allows you to confirm the authenticity of transactions.

    A centralized node is a node that can only be launched by a narrow circle of people, generally a project team or people close to it.

    Decentralized node - a node that can be run by almost anyone, which improves the security of the network.

Why is it worth participating?

⠀ So why is it worth to join in such activities?

    Firstly, this is a great opportunity to participate in top projects at the initial stages and get a reward for it.

    Secondly, participation in various projects allows you to gain experience, which in the future will allow you to easily cope with similar activities.

    Thirdly, it is an opportunity to become a validator in the main network, receiving a percentage of the commissions of processed transactions. This requires network users to delegate (put) project tokens to the node, and in some cases this is done by the team (generally in terms of hundreds of thousands of dollars). Solana, KiChain and Mina are instances.

Recently I try to participate everywhere, but so far I managed to get at least something only on Aiden / Eden (now I decided to kill the ass, I'm already tired of all these flips), but just enough to rent several servers for future experiments.

The other day I had to raise 3 nodes for Keep, but according to the instructions it was quite simple, although there was one pitfall.

With HOPR, I somehow did not grow together. In the first testnet, the bot didn't choose my node at all, and in the second, I was banned from Twitter, on which I posted the wallet address, after that, my result interrupted updating in the leaderboard.


not all testnets are paid this way, but getting even $ 100 for 15 minutes of work is extremely pleasant, isn't it? Especially considering that no investments are required from you.
The situation is a little more complicated with technical testnet.
They require the launch of a node - special software running on a constantly turned-on computer. Some technical knowledge is already needed here - starting from working with Linux OS, ending with renting a virtual server with the installation of a software package. In essence, a node is an ordinary computer that acts as a blockchain node.

Nodes can be divided into:
centralized and decentralized - those that can be run by a limited number of users (usually a development team) and those that can be run by anyone who decides to participate in the testnet;
complete and lightweight - with the storage of the entire history of the network or only those data that relate to transactions.
In any case, you will need a computer, a virtual server and a little patience. The cost of virtual servers starts from $ 5, but the costs will depend on the requirements of the project. For example, Solana testers spent up to $150 a month.
It is not known in advance how long the testnet will last, the process may take a year, although the average period is 1-3 months.

How much can you earn on a technical testnet? All participants of the Solana testnet got into the main network and now receive about 100 tokens per month.
