What exactly is a Blockchain?

A Blockchain is essentially a ledger. It is a ledger that keeps a record of digital transactions that take place over a network. In Blockchain technology, information is digitally stored in blocks which are then duplicated and distributed over a network of such blocks. Each of these blocks remains connected to each other with the help of nodes.

Nodes are individual computer systems which are spread across the globe. Anyone with an at par computer system can join the shared network constituting the Blockchain. These nodal systems ensure that all information stored in these blocks remains decentralized, public and without any possibility of being hacked, altered or manipulated.


Why am I hearing about Blockchain this much?

Blockchains have risen to prominence along with the rise in the cryptocurrency wave. Cryptocurrency has probably now reached the pinnacle of its popularity. From investing to maintaining portfolios to even keeping updated on the ups and downs of this viral yet measurable form of digital currency – all of it would not have been possible without Blockchain.

You ask how? This is how.

Cryptocurrencies use the same method of record-keeping as mentioned earlier. It uses blocks forming the Blockchain Technology to store data of the digital transactions that take place. Cryptocurrencies are a type of digital currency that has no central authority operating and controlling its transactions. Due to their great number of similarities, blockchain has thus become the ideal system of information storage related to cryptocurrency.

  • Patient information,
  • Managing the drug distribution network,
  • And above all, facilitating the confidentiality and security of patient health records.

Thus, it is a disservice to the concept of blockchain technology to reduce it to its mere functionality in the field of cryptocurrency. It harbours a wide range of applications and functions from which a considerable number of industries can benefit.

Simple, isn’t it? That is all you needed to know about the ABCs of Blockchain. Now when someone asks whether you know about it or not, tell them the exact three points listed above. These are likely to help you cover all significant bases before you decide to research further.
