Earlier we talked the need of Bitcoin.Now we will discuss what is Bitcoin.we are trying to define it .Bitcoin is a digital currency that is not backed by any country's central bank or government .Bitcoin transactions are made by digitally exchanging anonymous, heavily encrypted codes across a peer to peer network.The peer to peer network monitors and verifies the transfer of Bitcoins between users.Each user's Bitcoins are stored in a program called a digital wallet,which also holds each address the user sends and receives Bitcoins from ,as well as a private key known only to user.
Let's make it easier by comparing it with an email account.As we need an email account to send and receive emails similarly we need a wallet to send and receive Bitcoins.Once we have a wallet we need to generate our Bitcoin address,that is given to people to send and receive Bitcoins.Just like an email we need to protect or guard or account with a password.This password is known as secret key or private key in Bitcoin terminology.it can be done either writing on a piece of paper or any other medium,but what is more important is the security of account.Whoever knows it can access account.Even if we forget our password we can loose our Bitcoins too.
Every time we make a transactions through an address,the file gets updated.This file is called Blockchain. It is a public ledger of all Bitcoin transactions that have ever been executed. There is difference between bank
ledger and bitcoin ledger.In bank ledger we have address and balance whereas in bitcoin ledger we have addresses and balances ,but we don't know which address belongs to whom.it is transparent because anybody can see it
