Testnet

Definition

A separate blockchain network used for testing purposes.

Deep Dive

A Testnet is a separate, non-production blockchain network that mirrors the functionality of a Mainnet but operates using valueless test tokens instead of real cryptocurrency. Its primary purpose is to provide a safe, risk-free environment for developers to test new features, deploy smart contracts, experiment with upgrades, and debug applications before they are launched on the live Mainnet. This isolation prevents any potential bugs or security vulnerabilities from affecting real user funds or the stability of the primary network.
