They resemble testnets, but work differently. A node is a project program installed on a remote server, the operation of which must be monitored. The user needs to rent a server, install software on it according to the instructions and update it as needed. All necessary actions that the tester needs to perform are communicated by the project administrators. As a reward, participants receive project tokens or the opportunity to purchase them at a low price. Here, most often, you need investments on the server (from 5 to 30 bucks per month). The node will have to be kept from several weeks to several months. Costs depend on the server chosen. The only risk is that the project may not pay the reward - time and money will be wasted.
Required skills: ability to work according to clear instructions.
