What is Bitcoin? How to earn them?

Bitcoin is a peer-to-peer payment network and digital currency based on an open source protocol, which makes use of a public transaction log. Bitcoin was introduced in 2009 by pseudonymous developer Satoshi Nakamoto. It is called a cryptocurrency as it uses public-key cryptography. When paying with bitcoin, there will be no exchange of digital notes or tokens between buyer and seller. Instead, the buyer requests an update to a public transaction log, the blockchain. This master list of all transactions shows who owns what bitcoins currently and in the past and is maintained by a decentralized network that verifies and timestamps payments.  The operators of this network, known as "miners", are rewarded with transaction fees and newly minted bitcoins.

A blog or web log is a personal web site made up of usually short, frequently updated posts that are arranged chronologically. The content and purposes of blogs varies greatly from links and commentary about other web sites to observations about news or politics, diaries, photos, poetry, essays, project updates, even fiction. Blogs are a fast growing segment of the web. An article in the August 26, 2002 Newsweek estimated the number of blogs at 500,000 with a new one coming online every forty seconds.
