The Ethereum mainnet is the original and main network for the cryptocurrency and smart contract platform Ethereum. This is opposed to testnets, which are used for testing purposes.
The mainnet is the only network where Ether (ETH) has real value and can be exchanged for other cryptocurrencies or fiat currencies. The mainnet is also where users can create and deploy smart contracts. .
The Ethereum mainnet launched on July 30, 2015. Since then, it has undergone several hard forks, the most recent being the Constantinople hard fork in February 2019.
The hard fork was implemented to improve the scalability and efficiency of the Ethereum network.
The Ethereum mainnet is an important part of the overall Ethereum ecosystem. It is where users can access all the features of the Ethereum platform.
It is also where developers can test their applications before deploying them on a testnet or live environment.
