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

> eth.coinbase

> miner.start(1)

> eth.blockNumber

> miner.stop()

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

Here are the log file entries:

This is too fast. Increase the network difficulty level from 1000000 to 10000000 is needed to slow down the growth of the blockchain.
