Developers can test new features on the testnet, a secondary blockchain, without worrying about disrupting the main network. If new tools or products aren’t rigorously tested under a variety of conditions before being added to a live blockchain, there could be serious implications. In the worst situation, flaws could appear that hackers could exploit, costing individuals money. Developers will be closely monitoring the testnet while it is active for faults. Additionally, they might invite a few users to test the blockchain in order to receive helpful feedback.
After being tested on a testnet, a feature may then be added to the mainnet. Decentralized networks, on the other hand, can require that ecosystem participants be given the chance to vote first. Additionally, testnets can offer a useful simulation tool that enables users to experiment with cryptocurrencies and attempt new things risk-free.
