Hello, new friends in the crypto world! Today, we’re going to talk about two concepts that often pop up in the crypto space but can be confusing for newcomers: Mainnet and Public Blockchain (公链). Whether you’re a complete newbie or someone with some experience, understanding these concepts is key to successfully navigating the blockchain ecosystem and making informed investments.

What is a Mainnet?

A Mainnet (主网) refers to the official, fully functioning version of a blockchain project that allows for real transactions and the execution of smart contracts. Simply put, the Mainnet acts like a giant digital ledger that records every participant's transactions and data.

Distinction from Testnet: The functionalities of a Mainnet can be tested and verified through a Testnet (测试网). A Testnet is a simulated environment where developers can experiment with their applications and protocols without risking real currency loss. In other words, the Mainnet is the “real deal,” while the Testnet is merely an experimental ground.

Launching the Mainnet: Generally, a blockchain project undergoes extensive testing on a Testnet before it goes live on its Mainnet. Once testing is complete and functions are confirmed to be error-free, the project team will launch the Mainnet, marking the official start of the project.

Comparing Public Blockchains to Private Blockchains

A Public Blockchain (公链) is a blockchain network that is open for anyone to participate, with key characteristics including openness, transparency, and decentralization. In contrast, a Private Blockchain (私链) is controlled by specific organizations or entities, with participants requiring authorization to join.

1. Characteristics of Public Blockchains:

• Decentralization: No central authority controls the network, allowing each node to participate equally.

• Anonymity and Transparency: Users can transact anonymously, but all transaction data is publicly available.

• Consensus Mechanisms: Public Blockchains typically utilize various consensus mechanisms (like Proof of Work and Proof of Stake) to ensure network security and fairness.

2. Characteristics of Private Blockchains:

• Centralized Management: Only authorized users can participate, suitable for internal enterprise management.

• High-Speed Transactions: With fewer participants, transaction confirmation speeds are faster.

• Data Privacy: Private Blockchains can limit data access, making them suitable for situations that require confidentiality.

  
  

The Relationship Between Mainnets and Public Blockchains

The relationship between Mainnets and Public Blockchains can be likened to a home and its front door. The Mainnet acts as the home where all the real transactions and activities occur, while the Public Blockchain serves as the entrance that allows anyone to enter.

Technical Architecture: Public Blockchains like Ethereum and Bitcoin each have their own Mainnet. These Mainnets support all transactions and smart contract executions on their respective chains.

Ecosystem Development: Various decentralized applications (DApps) can be developed and run on the Mainnet of a Public Blockchain. Different projects can utilize the same infrastructure within the Mainnet, enhancing interoperability and making it easier for developers to create new products.

Real-Life Applications of Mainnets

Let’s look at a couple of real-life applications of Mainnets:

Ethereum: Ethereum is a fully public blockchain with its own Mainnet that supports decentralized applications and smart contracts. The Ethereum Mainnet allows anyone to create and launch their own DApps.

Bitcoin: Bitcoin, the first and most well-known Public Blockchain, has its Mainnet designed to handle Bitcoin transactions, ensuring network security and decentralization.

Conclusion

Understanding the concepts of Mainnets and Public Blockchains is crucial for new investors in the crypto space. The Mainnet serves as the actual blockchain environment where transactions and applications happen, while the Public Blockchain offers a fair and transparent platform for society. I hope this article helps you grasp these fundamental concepts, building a solid foundation for your journey into the world of cryptocurrencies!
