What is a Blockchain?
A blockchain is a decentralized digital ledger technology that records transactions across a network of computers in a secure, transparent, and immutable manner. Each transaction is grouped into a “block” and linked together in chronological order, forming a “chain.”
It operates without a central authority, relying on consensus algorithms to validate and add transactions. This technology is known for its security, as altering any data in a block would require changing the entire chain, making fraud extremely challenging.
Blockchains have diverse applications, from powering cryptocurrencies like Bitcoin to revolutionizing industries like finance, supply chain management, and healthcare with transparent and tamper-proof record-keeping.
Take a look at the following image to comprehend the growing popularity of blockchain technology in the global market in recent years –

How Does Blockchain Work?
Understanding how blockchain works is essential to grasp its transformative potential across various industries.
Here is a look at an image first that will help you understand the intricate workings of blockchain technology and the process by which transactions are validated and added to the blockchain –

The functionality of blockchain can be broken down into the following steps:
Step 1: Transaction Creation
When a user initiates a transaction (like sending cryptocurrency or recording data), this transaction is broadcast to a network of computers known as nodes.
Step 2: Transaction Verification
These nodes validate the transaction against a set of predetermined criteria. For example, in the context of cryptocurrencies, nodes check if the sender has the necessary funds to make the transaction.
Step 3: Block Formation
Once verified, the transaction is grouped with other transactions to create a new data block. This block contains a reference to the previous block through a unique code called a ‘hash,’ creating a chain of blocks.
Step 4: Consensus Mechanism
Before a new block can be added to the chain, network participants must agree (reach consensus) that the block is legitimate. This is achieved through consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS).
Step 5: Adding to the Blockchain
Once consensus is reached, the new block is added to the blockchain, and the transaction is considered complete. This updated blockchain is then propagated across the network, ensuring all nodes have the latest version.
Step 6: Immutable Record
After a block is added to the blockchain, altering any data within it would require consensus from a majority of the network, making it nearly impossible to alter a block undetected.
Types of Blockchains
There are 3 main types of Blockchains. They are public, private, and consortium blockchains. Here are the 3 types of Blockchain –

1. Public Blockchains
Public blockchains open the door for participation and transparency, offering a decentralized ecosystem accessible to all.
- Inclusivity: Public blockchains welcome users from all corners, allowing anyone to join.
- Participation: Users actively engage in decision-making processes, adding to the network’s democratic nature.
- Transaction Validation: Participants collectively validate transactions, ensuring their integrity and security.
- Mining Opportunities: Public blockchains like Bitcoin and Ethereum offer mining opportunities for users to contribute and earn rewards.
2. Private Blockchains
Private blockchains, in contrast to public ones, operate within specific boundaries, providing enhanced control at the cost of decentralization.
- Access Control: Private blockchains limit access to predefined users or organizations.
- Controlled Transactions: These networks offer greater control over transaction validation and mining, often favored for business applications.
- Privacy Emphasis: Businesses prioritize privacy and data control when using private blockchains.
- Example: Companies utilize private blockchains for internal data tracking, maintaining security and control over sensitive information.
3. Consortium Blockchains
Consortium blockchains strike a balance between public and private, governed by a group of businesses rather than a single entity.
- Shared Governance: Multiple businesses within a consortium collectively manage the blockchain.
- Consensus Decision: Consortiums decide on the consensus mechanism and network participants.
- Business Collaborations: These blockchains are ideal for collaborative endeavors, offering shared access to data.
- Use Cases: Consortium blockchains find applications in scenarios where multiple parties require access to shared data, such as supply chain management or industry-specific collaborations.
What is Blockchain Application?
A blockchain application, often referred to as a DApp (Decentralized Application), is a software application that runs on a decentralized computing system, primarily using blockchain technology. Unlike traditional apps, where the backend code runs on centralized servers, DApps run on a peer-to-peer network.
Here’s a deeper look:

From enhancing transparency to simplifying cumbersome processes, now we explore how blockchain is reshaping the property market landscape through an image.

1. Tokenization of Assets
The concept of asset tokenization is turning the traditional approach to real estate on its head. Rather than buying a property as a whole, blockchain enables properties to be divided into digital shares or tokens. Think of it like buying stock in a company.
This means that investing in real estate, traditionally a domain for the affluent due to its high entry barriers, becomes accessible to a broader audience. It not only democratizes property investment but also offers liquidity.
A token holder can trade their shares in secondary markets, introducing a level of flexibility previously unseen in real estate.
2. Smart Contracts in Real Estate
The real estate transaction process is often lengthy, involving numerous intermediaries – lawyers, brokers, notaries. Enter smart contracts: self-executing contracts with terms of the agreement directly written into lines of code.
Through blockchain, processes such as due diligence, payments, and transfer of property rights can be automated, significantly reducing the need for middlemen. The result? Faster transactions, reduced costs, and less room for human-induced errors.
3. Property Search and Verification
One of the perennial issues plaguing the real estate sector is the authenticity of property details. With blockchain, every property can have a transparent and immutable record detailing its history, previous owners, and any incidents like natural calamities or disputes.
Potential buyers can independently verify this data, eliminating dependencies on agencies or brokers for genuine information. This builds trust and expedites the decision-making process for buyers and sellers.
4. Cross-border Transactions
International property deals have always been mired in bureaucracy, high fees, and prolonged waiting periods due to currency exchanges and regulatory procedures.
Blockchain offers a organised solution. With cryptocurrencies like Bitcoin or Ethereum, cross-border transactions can be settled within minutes, irrespective of the amount.
As digital currencies are borderless by nature, they effortlessly bypass conventional banking systems, slashing transaction costs and time.
