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.","detailed_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.","format":"paragraph","confidence":85,"verified_at":"2026-09-14 12:40:21","updated_at":"2026-09-14 21:40:21"},"sources":[{"id":4,"title":"Ethereum networks","url":"https://ethereum.org/en/developers/docs/networks/","publisher":"ethereum.org","type":"official","accessed_at":"2026-09-14 12:40:21"}],"published_at":"2026-09-14 12:40:21"}
