What Is Ethereum Testnet: Ropsten Network
This section describes what is Ethereum Testnet: Ropsten Network.
Ropsten Network, also called "testnet", is a pre-configured proof-of-work Ethereum test network.
The main purpose of Ropsten Network is for developers to test their Ethereum related applications.
On the Ropsten Network, the Ethereum money "Ether" has no real value. You can get Ether funds for free.
The blockchain on the Ropsten Network is also much shorter. As of 2018, the Ropsten Network blockchain has 2,768,369 blocks, comparing to 5,195,203 blocks in the Ethereum main network.
Blocks are much smaller on the Ropsten Network. So you can synchronize with Ropsten Network much faster than the main network.
