Bitcoin is the first ever digital cash which follows peer-to-peer networking system. Blockchain is the outcome of many decades of research and breakthroughs in the security system of digital or virtual currency.
Blockchain is a decentralized digital ledger which is very much helpful in the anonymous transactions, thus it is being considered as the back bone to the present day transaction policies. Blockchain networking totally relies on the users and doesn’t involve in any of the central authority, this feature makes the usage very much interesting.
All the transactions under the Blockchain technology are made together or grouped together into a block and are supposed to follow strict cryptographic rules.
The basic advantage of using the blockchain technology is that the transactions once recorded can’t be altered or changed by which double spending can be prevented.

We can find no central authority over the bitcoins, but we have a limit of about 21 million to the bitcoin. At present there are about 17 million in circulation.
For each and every transaction a private key generally used as a signature is generated from the cryprto wallet to provide a mathematical proof that the request has come from the owner. Bitcoin verifies each and every transaction with encryption of state-of-art which is often used in banking and has many other applications.
