What is Blockchain?

In simply words it is an ever-growing database with specific data and extraordinary features:

  1. Data entered in Blockchain database cannot be altered or deleted. Once entered it stays forever.
  2. No single entity is responsible for database management, it is handled by number of users, each having copy of the data.

In blockchain a folder is shared with a network of users, if anyone wants to make changes to the shared file he has to make an announcement which is noted by everyone. The content shared with all cannot be altered once locked. The fastest person is rewarded with some amount of digital currency.

Once the file is locked it is added to a folder and a new page is shared with the users. This is an ongoing process that will work like this forever.

As the time passes the pages (blocks) that have the important details (transaction) are added to the folder (chain) thus forming database blockchain.
