In our daily life we usually hear about Encryption / Decryption of data used for the purpose of security.
Now the same concept applies for the transfer of currency, that currency is known as BITCOIN and the concept is called “Crypto Currency”. It’s a digital currency implemented on the bases of open source, peer to peer internet protocol.
This concept was discovered in 1998 by Wei Dai on the cypherpunks mailing list, & came into implementation in 2009 by a Pseudonymous developer named Satoshi Nakamoto published in Cryptography Mailing List.
A single Bitcoin can divided into 100 million smaller units, called Satoshis. A Bitcoin can be transfer simply from a personal computer through the use of wallet file or a website, without any participation of financial institution. Bitcoins has no Central Bank. Once the transaction has submitted then it cannot be altered. The supply of Bitcoins is limited, divided, scheduled & divided. Bitcoin Mines or Block Chains verify the Bitcoin transaction & add them to transaction log. The total implemented time for transactions is about 10 to 60 minutes.
By the end of 2010 Sathoshi left the searches and moved to other projects. Now the value of Bitcoin going downward slowly, in July 2011 Bitcoins now again climbed up towards heights & in Sept 2012 Bitcoin Foundation came into existence.
