-Networks are different Ethereum environments you can access for development, testing, or production use cases. Since Ethereum is a protocol, there can be multiple independent "networks" that conform to the protocol without interacting with each other.
+Ethereum networks are groups of connected computers that communicate using the Ethereum protocol. There is only one Ethereum Mainnet, but independent networks conforming to the same protocl rules can be created for testing and development purposes. There are many independent "networks" that conform to the protocol without interacting with each other. You can even start one locally on your own computer for testing your smart contracts and web3 apps.
 
 Your Ethereum account will work across the different networks, but your account balance and transaction history won't carry over from the main Ethereum network. For testing purposes, it's useful to know which networks are available and how to get testnet ETH to play around with. In general, for security considerations, it's not recommended to reuse mainnet accounts on testnets or vice versa.

 Most testnets started by using a permissioned proof-of-authority consensus mechanism. This means a small number of nodes are chosen to validate transactions and create new blocks – staking their identity in the process. Alternatively, some testnets feature an open proof-of-stake consensus mechanism where everyone can test running a validator, just like Ethereum Mainnet.
 
-ETH on testnets has no real value; therefore, there are no markets for testnet ETH. Since you need ETH to actually interact with Ethereum, most people get testnet ETH from faucets. Most faucets are webapps where you can input an address which you request ETH to be sent to.

Since you need ETH to actually interact with Ethereum (even on testnets), most people get testnet ETH for free from faucets. Most faucets are webapps where you can input an address which you request ETH to be sent to.

 ### Layer 2 testnets {#layer-2-testnets}
 
 [Layer 2 (L2)](/layer-2/) is a collective term to describe a specific set of Ethereum scaling solutions. A layer 2 is a separate blockchain that extends Ethereum and inherits the security guarantees of Ethereum. Layer 2 testnets are usually tightly coupled to public Ethereum testnets.
