What is Blockchain Technology?
Imagine a record-keeping book that’s not kept in one place but copied and spread across a network of computers. Whenever someone adds a new page to this book, everyone’s copy gets updated. This is the essence of blockchain technology. It’s a way of storing information in a manner that makes it tough to cheat, hack, or change the system. At its heart, blockchain is a chain of blocks, but not in the traditional sense of those words. Here, “block” refers to digital information (the transactions) stored in a public database (the “chain”).
Blockchain technology offers a decentralized platform. This means it doesn’t rely on a single central point of control. A good analogy is a shared document or spreadsheet duplicated thousands of times across a network of
computers. The network is designed to regularly update this document, ensuring all copies are the same and true.
This technology came into the spotlight with the rise of digital currencies like Bitcoin, but it’s proving to be useful far beyond, creating a foundation for a new type of internet. Originally designed for the digital currency, tech communities are finding other potential uses for the technology.

What are the Key Components of Blockchain Technology?
Understanding blockchain technology means knowing its key parts. These components ensure transactions are securely logged, checked, and kept over a decentralized network. Below are the vital parts of any blockchain system:
Block:
A block is the smallest unit in a blockchain and holds data. It stores details of transactions, including the sender, receiver, and the amount transferred. Each block has a unique identifier known as a “hash,” setting it apart from others.
Chain:
Blocks connect in a specific sequence, forming a chain. Each block points to the hash of the one before it, creating a time-ordered trail of data. This structure safeguards the blockchain’s integrity, as altering any information would mean changing all subsequent blocks, a near-impossible task.
Node:
A node is a computer connected to the blockchain network. Its jobs include validating,
storing, and distributing blocks. All nodes have the blockchain’s entire history, updated with new blocks as they are approved and attached.
Consensus Mechanism:
This method achieves agreement on transactions’ validity across the network’s nodes. Blockchains employ different consensus mechanisms, like Proof of Work (PoW) or Proof of Stake (PoS), to protect the network and confirm transactions.
Cryptography:
Blockchain relies on cryptographic methods to secure block data. This ensures only those with the correct private key can access the information, offering privacy and security.
Smart Contracts:
These are automated contracts whose conditions are coded directly into the blockchain. Smart contracts execute on their own when conditions are met, eliminating the need for central authorities or external enforcement.

Blockchain is a form of DLT, recording transactions with an unchangeable cryptographic signature, a hash. Any alteration in a block is immediately noticeable, making blockchain resistant to fraud and hacking.
These components unite to form the secure and resilient system blockchain is celebrated for. They support various uses, from financial dealings and supply chain oversight to verifying identities, transforming our approach to data security and exchange in the digital age.
How Does Blockchain Work?
To understand how blockchain technology operates, we must explore the journey of a transaction from initiation to its inclusion in the blockchain. This explanation simplifies the intricate process involved.
Transaction Initiation:
The journey begins with a user sending a digital currency to another. This step involves specifying the digital addresses of both the sender and receiver, alongside the amount being sent.
Transaction Verification:
For a transaction to join the blockchain, nodes or network participants must verify it. The blockchain might employ different verification methods, such as Proof of Work (PoW) or Proof of Stake (PoS).
Forming a Block:
After verification, the transaction is grouped with other recently verified transactions to form a new block. Each block not only contains transaction data but also a unique code, or hash, and the hash of the preceding block in the chain.
Adding the Block to the Chain:
This new block must be appended to the existing blockchain. A consensus mechanism ensures multiple network nodes agree on the validity of the block’s transactions and its hash. This consensus prevents any single entity from manipulating the blockchain.
Permanence and Transparency:
Once a block is part of the chain, it’s permanent and immutable. Blockchain’s key feature is this immutability. While transactions on the blockchain are transparent and open for viewing, the identities of the participants remain protected and anonymous.
Proof of Work vs. Proof of Stake:
- Proof of Work (PoW): A consensus mechanism requiring participants to solve complex problems to verify transactions and create blocks. The first to solve the problem adds the block to the blockchain and receives a reward. Bitcoin uses PoW.
- Proof of Stake (PoS): As an alternative to PoW, PoS allows users to verify transactions and create new blocks by holding and staking cryptocurrency. It’s considered more energy-efficient than PoW.
Ensuring Security and Trust:
Blockchain’s design and cryptographic techniques render it highly secure. Its decentralized nature eliminates any single point of failure, enhancing network security. The consensus requirement for transactions ensures accurate recording and verification by multiple parties, building trust.
