Mainnet
The live, real version of a blockchain network where transactions have real value.
Mainnet refers to the main, publicly live version of a blockchain network, as opposed to a test version. Transactions on mainnet involve real assets and real value.
When a project says it has "launched on mainnet," it means the network or application is live and operating for real use, not just being tested in a controlled environment.
Examples
- Ethereum's mainnet is the live network where real ETH and real transactions exist.
- A project typically tests thoroughly on a testnet before deploying to mainnet.
