We have often heard about a Central Server or computer or node connected to the internet and storing information online, but,
what if I say, a Decentralized system or setup connected to the internet and storing the information online.
And the Decentralized setup which I talked about above is what we call it BlockChain.
Blockchain, sometimes referred to as Distributed Ledger Technology (DLT), makes the history of any digital asset unalterable and transparent through the use of decentralization and cryptographic hashing.
A simple analogy for understanding blockchain technology is a Google Doc. When we create a document and share it with a group of people, the document is distributed instead of copied or transferred. This creates a decentralized distribution chain that gives everyone access to the document at the same time.
No one is locked out awaiting changes from another party, while all modifications to the doc are being recorded in real-time, making changes completely transparent.
Of course, blockchain is more complicated than a Google Doc, but the analogy is apt.
3 Important Concepts of Blockchain
- Blocks: Every chain consists of multiple blocks that are interlinked to each other. Also, each block contains three basic elements which are data, hash & hash of the previous block.
- Miners: Miners create new blocks on the chain through a process called mining. Making a change to any block earlier in the chain requires re-mining not just the block with the change, but all of the blocks that come after. This is why it’s extremely difficult to manipulate blockchain technology. When a block is successfully mined, the change is accepted by all of the nodes on the network and the miner is rewarded financially.
- Nodes: Nodes can be any kind of electronic device that maintains copies of the blockchain and keeps the network functioning. Every node has its own copy of the blockchain and the network must algorithmically approve any newly mined block for the chain to be updated, trusted, and verified. Since blockchains are transparent, every action in the ledger can be easily checked and viewed. Each participant is given a unique alphanumeric identification number that shows their transactions.
How does the Blockchain Ecosystem works?
Blockchain Technology had a great introduction to the world when BITCOIN came into existence.
But, actually, Bitcoin was a kind of incentive paid to people who were helping to maintain the Blockchain Ecosystem in the form of currency.
Hope, you got some kick of what this BIG DADDY term BLOCKCHAIN means.

Concept is great but ample of hindrances are there for this ecosystem to enter India
