Introducing a new product or feature into a blockchain main network can be challenging because of the consequences if anything goes wrong. 

‍

However, Testnet has been developed to make it easier for developers to test run their products or inclusive features for faults before bringing them to live in the main network. 

‍

What are Testnet?

‍

A Testnet is a blockchain designed to test new inclusive features, and defi applications before introducing them into the mainnet. ​​

‍

It’s common for every blockchain project to have a testnet, which aids developers in experimenting with their ideas without altering the features and running of the main network blockchain. 

‍

Example of Testnets:

‍

• Ethereum testnet
• Smartchain testnet
• Algorand testnet 
• Polygon testnet
• Goerli testnet
• Zilliqa testnet

Why Are Testnet Important in Blockchain

‍

Imagine launching a dapp without testing it, and the swap option isn’t working. How traumatic will that be for users?

‍

Developers know this, and that’s why testnet plays a vital role in:

‍

Experiment

‍

A testnet allows developers to experiment with their projects, to ensure it’s free from bugs, faults, or anything that will alter the smooth running of the project. 

‍

After they have fully tested their project on the testnet and are satisfied then they can then cast a vote in case of a  DAO, and then launch the project or the feature on the mainnet. 

‍

In addition, any inclusive feature or project on a mainnet must pass through the testnet to avoid jeopardizing the main network. 

‍

Free to Use

‍

Testnet is free to use, all resources are provided for developers all for free to fully test run their project before launching them in the mainnet. 

‍

This helps developers to focus on finding errors, and bugs within their codes, and getting user interaction feedback to confirm they are on track. 

‍

Conclusion

‍

Testnet is the general term given to subordinate blockchain that’s designed to test run project or new feature before they are launch in the main network. This is done to verify that a project or feature is free from errors and is ready to be deployed on the main network.
