A testnet is a separate blockchain network specifically designed for testing and experimentation purposes. It functions as a replica of the mainnet (live) network but operates with test tokens that have no real-world value. Testnets allow developers, researchers, and users to experiment with new features, test smart contracts, and identify and resolve issues before deploying applications on the mainnet. They provide a safe and controlled environment for testing without the risk of losing real assets. Testnets are essential for ensuring the functionality, security, and stability of blockchain applications and protocols before their release to the public.
