∟Run "miner" with Lower Difficulty

This section describes how to run 'geth' miner with lower difficulty level.

With the "geth" node running on my private Ethereum network with the initial difficulty set to 1000000, I am ready try the 'miner' again:

> eth.blockNumber
0

> eth.coinbase
"0x05d4e1a499775ce9d681abd50bda655c7b5ccb90"

> miner.start(1)
null

...
> eth.blockNumber
11

> miner.stop()
true

Wow! Within 2 minutes, I got 11 new blocks mined!
