Testnet is also called Ropsten and is the widely used test network for the Ethereum blockchain.
This test blockchain is used to test smart contracts and DApps before being deployed to the production live blockchain.
Ropsten, Rinkeby, Kovan, and When to Use Each (Part 2)
Moreover, being a test network, it allows experimentation and research.
The main testnet is called Ropsten which contains all features of other smaller and special purpose testnets that were created for specific releases.
For example, other testnets include Kovan and Rinkeby which were developed for testing Byzantium releases.
The changes that were implemented on these smaller testnets has also been implemented on Ropsten.
Now the Ropsten test network contains all properties of Kovan and Rinkeby.
Why This Matters for Blockchain Technology
Understanding Testnet is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
