If you've been around the blockchain block, you would have likely encountered the terms ‘testnet’ and ‘mainnet’. For those new to the scene, these are essentially test and live environments to simulate Web3 projects before they’re released to the world — the name of the terms may already be telling.
As we demystify testnet and mainnet this guide, we’ll also cover their respective tokens, and their respective utilities, with a case study on aelf's AI blockchain.
Whether you're a budding developer eager to build on the blockchain, a curious investor exploring new opportunities, or simply someone intrigued by this groundbreaking technology, we’ll start by revisiting the underlying concept of a blockchain network.
Recap: What's a Blockchain Network?
Blockchain networks are transforming how we handle data, transactions, and trust. Picture a global digital ledger that operates independently — no single person or company controls it, yet everyone can trust its security and accuracy.
Each ‘block’ in the chain holds a list of transactions, and once data is recorded, it cannot be altered, ensuring transparency and eliminating any single point of failure. Curious about the inner workings of blockchain layers?

The Role of the Testnet: Your Blockchain Test Track
Testnet: Your Test Drive Before The Open Road
Ever wonder how developers make sure their blockchain projects are ready for the main highway? That’s where the testnet comes in. Think of it as a test track for blockchain applications — a place where developers can take their code for a spin without real-world consequences. Whether they’re testing smart contracts, transaction fees, or new dApps, testnets offer a safe, risk-free environment to fine-tune and improve blockchain projects before hitting the open road of the mainnet.
Key Functions of a Testnet
Testnets are vital for ensuring the reliability and functionality of blockchain applications before they go live. They provide a controlled environment where new code can be tested and improved.
For instance, Ethereum’s Ropsten and Rinkeby testnets allow developers to trial smart contracts and dApps in a setting that closely resembles the mainnet. Similarly, aelf’s testnet replicates the conditions of the main blockchain, enabling developers to identify and resolve potential issues in a risk-free setting.
Testnet Tokens: The Fuel for Your Blockchain Test Drive
While testnet tokens hold no monetary value, they are invaluable in simulating transactions and interactions within the testnet environment. Distributed for free through faucets, these tokens allow developers to thoroughly test their applications without risking actual cryptocurrency. This way, they can ensure that everything runs smoothly before transitioning to the mainnet, just like ensuring your automobile performs well before hitting the highway.

How Do Users Usually Get Hold of Such Tokens?
Testnet tokens are often distributed through faucets — websites or services that provide tokens for free to users. Developers and testers can request these tokens to simulate transactions and interactions in the testnet environment, ensuring their projects work as expected before going live.
As an example, you can check out aelf's faucet, where you can earn ELF tokens by trialing the aelf wallet.
What Can You Do with These Tokens?
While testnet tokens function like ‘monopoly money’ — they can’t be used for real-world transactions — they are essential for testing blockchain applications.
Users can use them to simulate transactions, deploy contracts, and interact with dApps in the testnet environment. This helps developers ensure that their projects are functioning correctly before they go live.

The aelf testnet can be your AI-powered blockchain playground to put a Web3 idea to the test. Experiment, build, and explore without any real-world financial risk, or simply experience the power of aelf's AI blockchain technology firsthand.
To join the aelf testnet, you'll first need to set up the required database (SSDB) and import the latest snapshot data. Next, generate an account for your node using the 'aelf-command' tool and configure the node settings in the appsettings.json file, including your account details, database connection strings, and bootnode peers.
You can then run the node using either Docker (recommended), or by executing the binary release or compiling from source. If you're running a sidechain node, additional configuration is needed to connect it to the mainchain. Finally, check your node's status by querying its block height.

Onto the Mainnet: Where the Real Action Happens
Mainnet: The Open Road of Blockchain
When a blockchain project transitions from testnet to mainnet, it’s like moving from a test drive to the open road. The mainnet is the live blockchain network where real transactions take place, and real assets are at stake. This is where users interact with the blockchain, making the security and functionality of the mainnet crucial to the network’s success.
Mainnet Tokens: The Real Deal
Mainnet tokens are the lifeblood of the live blockchain. Unlike testnet tokens, these have real-world value and are used for transactions, staking, or accessing various features within the blockchain ecosystem. For example, Ethereum’s ETH and Bitcoin’s BTC are mainnet tokens with significant value and utility in their respective networks.
Transitioning from Testnet to Mainnet: A Critical Milestone
Moving from testnet to mainnet is a pivotal step for any blockchain project. It involves migrating code and data from the test environment to the live network. This process requires thorough testing and validation to ensure that the application functions as intended and can handle real-world usage.
Why Testnets and Mainnets Matter
1. For Developers: A Safe Space to Test Drive
Testnets provide developers with a risk-free environment to test and iterate on their projects. They allow for experimentation with new features and the resolution of issues before launching on the mainnet. This ensures that when a project goes live, it is robust, secure, and ready for the real highway.
2. For Users and Investors: Understanding the Difference
For users and investors, knowing whether a project is in testnet or mainnet can be a key factor in evaluating its maturity and potential value. Testnet tokens are for testing only, with no monetary value, while mainnet tokens are the real deal, used for transactions and investments. Understanding this distinction helps in making informed decisions about engaging with blockchain projects.
3. For the Blockchain Ecosystem: Driving Innovation and Security
Testnets play a vital role in the blockchain ecosystem by fostering innovation and development. They allow projects to refine their technology and contribute to a more robust and secure mainnet. This iterative process helps advance the blockchain industry, not excluding aelf's lead-up to an AI blockchain phase; we rely on this same process to result in more reliable applications.
Testnet vs. Mainnet Tokens: Key Differences to Keep in Mind
1. Value and Utility: The Test Track vs. The Highway
The primary difference between testnet and mainnet tokens is their value. Testnet tokens are used solely for testing and have no intrinsic value, while mainnet tokens have real-world value and are used for transactions, investments, and accessing blockchain services.
2. Acquiring and Using Tokens: Test Drive vs. Real Deal
Testnet tokens are acquired through faucets or project distributions, while mainnet tokens can be purchased on exchanges, earned through staking, or received as rewards. Mainnet tokens facilitate real transactions within the blockchain ecosystem, making them the true currency of decentralised Web3 applications.
3. Risks and Considerations: Test Track vs. Highway Hazards
Using testnet tokens has minimal risk since they have no intrinsic value. However, mainnet tokens carry financial risks, including price volatility and potential loss of assets. It’s essential for users and investors to conduct thorough research and understand these risks before engaging with mainnet tokens.
In Closing
Testnets and mainnets are essential parts of the blockchain know-how. In short, testnets provide a safe space for experimentation and development, while mainnets represent the live, operational networks where real value is at stake.
By being able to discern the differences between them, these environments and their tokens can help developers, users, and investors make informed decisions and engage effectively with blockchain technology, whether they’re test-driving a new blockchain application or cruising the live blockchain network.
