Bitcoin Mining Continued..

In the previous blog, we have described about what a miner is, what does a miner do, and why do we need mining. Building on these points, in this blog we'll see what does a Blockchain look like, what does Proof-of-Work and mining difficulty mean, and how can you start mining for yourself.
