Quick answer
What is a blockchain mainnet?
A blockchain mainnet is the live, production network of a blockchain where real transactions are processed, validated and permanently recorded. Unlike a testnet, mainnet assets have real economic value. Launching a mainnet requires its own consensus mechanism, validator or node infrastructure, native token economics and network rules.
