recently, I have been looking at something related to Ethernet Fang. There is a question about testing network mining that is not clear, as follows:
I use miner.start () to dig mines here, young and old, but when I go to Ropsten Testnet , I can find my address, but the number of ETH below is 0. later, I looked it up on the Internet and said that the coins in the test network could only be obtained through some places. For example, here http://faucet.ropsten.be:3001. Here I am confused by B, what is dug in miner.start () , I am running in the test network, why can"t I find it through Ropsten testnet ?
would like to know the great god to explain, thank you
