There are several types of Ethereum networks that exist. The main ones are:
-
Mainnet: This is the main Ethereum network where actual transactions and smart contracts are executed. It is the live network where Ether (ETH) is used as the native cryptocurrency.
-
Testnets: These are separate Ethereum networks used for testing purposes. Testnets allow developers to test smart contracts and dApps without using real Ether. The most common testnets are Ropsten, Kovan, and Rinkeby.
-
Private/Permissioned Networks: These are Ethereum networks that are operated by a specific group of individuals or organizations. Access to these networks is restricted and participants need permission to join. These networks are often used for enterprise applications or consortiums.
Each of these networks serves a different purpose and caters to various needs within the Ethereum ecosystem.
