Quick answer
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.

Answer
Mainnet is the final stage of a blockchain release cycle: devnet, testnet, then mainnet. Once live, protocol changes require coordinated upgrades across node operators. Independent mainnets such as Ethereum run their own validator sets, while application chains and Layer 2 networks may inherit security from a base mainnet.
