Mainnet
Quick Answer
Mainnet is the production blockchain where real transactions occur, as opposed to testnets used for development. Going live on mainnet means processing real customer payments.
Full Definition
Mainnet is the production version of a blockchain network where real transactions with real economic value occur. It is distinct from testnets, which use valueless tokens for development and testing. Payment integrations are first built and tested on testnets before being deployed to mainnet. Going live on mainnet means processing real customer payments with real cryptocurrency.
