What Is Blockchain?

Simply put, Blockchain is nothing but a data structure. That is, it allows to store data systematically. Thus, Blockchain technology allows to store data in an organized way. So, where’s the difference? To start with data stored on Blockchain cannot be modified. This allows a transparent transaction between parties. The data stored in the blocks is permanent. An alteration in any of the blocks cannot happen unless changes in the linked blocks are collaboratively allowed.

To further understand, you can compare it with a ledger that keeps record of all interlinked financial transactions. The only difference here is that all the data is digital and not stored at one place. Thus, decentralization makes it tough for the cyber criminals to get their hands on the required information. Blockchain works on a peer to peer networking model. It is not handled by a single entity but by multiple across the network. No central source of authority, makes it more robust and secure against cybercrimes.

Each block is connected with a hash pointer which is the link between blocks. The block also has information about the technical details and relevant reference about the information of the previous block. To trace back, each block refers to the preceding hash pointer.

Does It Have a History?

Well yes! Blockchains go way back into 1990’s. The foundation of the concept was first laid by Stuart Haber and W. Scott Stornetta in the year 1991. While the world was still getting used to computers and internet was only known to a handful of the world population, they introduced cryptographically secured chains of blocks. However, at that time their need of the hour was to collate large data at one place.
