What is Mainnet Launch?
Mainnet launch is the transition of a blockchain from testnet to its live production network where transactions involve real value and tokens can be traded.
How does Mainnet Launch work?
- Network runs on testnet using valueless tokens for testing.
- Developers fix bugs discovered during testing.
- A specific block height or timestamp is set for the transition.
- Validators update their software to support the live network.
- The genesis block is created, officially starting the live chain.
Why does Mainnet Launch matter?
It transforms a software project into a functional economic system with irreversible transactions, real security, and deployable production applications.
Key features of Mainnet Launch
- Transition from testing to production
- Real tokens with market value
- Requires validator coordination
- Often accompanied by exchange listings
Examples of Mainnet Launch
Bitcoin launched on January 3, 2009 with the genesis block. Ethereum launched July 30, 2015.
Solana launched in March 2020. When Arbitrum launched its mainnet, users could finally bridge real ETH and use DApps with actual value.
