Blockchain technology is a decentralised, distributed ledger that revolutionizes how we record and manage transactions. At its core, a blockchain is a digital ledger that stores records of transactions in a way that’s immutable and tamper-resistant. Unlike traditional databases, where a central authority controls the data, a blockchain is decentralised. It’s maintained by a network of computers (nodes) that reach consensus on the validity of transactions

How does it work?

When a new transaction occurs (for example, transferring cryptocurrency or recording ownership of an asset), it’s grouped into a block. Each block contains a hash (a unique identifier) of the previous block, creating a chain. Once a block is added to the chain, it cannot be altered. This immutability ensures trust and transparency. Consensus algorithms (such as Proof of Work or Proof of Stake) ensure that all nodes agree on the validity of transactions

Key Features

• Decentralisation: No single entity controls the entire blockchain
• Transparency: All participants can view the entire transaction history
• Security: Cryptography prevents unauthorized changes
• Smart Contracts: Self-executing contracts with predefined rules
• Permissioned vs. Permissionless: Some blockchains require permission to participate (e.g., private enterprise blockchains), while others are open to anyone (e.g., Bitcoin)

Use Cases

• Cryptocurrencies: Bitcoin and other digital currencies operate on blockchains
• Supply Chain: Tracking goods from origin to consumer
• Healthcare: Securely managing patient records
• Finance: Faster cross-border payments
• Real Estate: Recording property ownership
• Identity Management: Verifying identities without intermediaries

Why It Matters?

• Trust: Blockchain eliminates the need for intermediaries (banks, governments) by providing a transparent, tamper-proof record
• Efficiency: Streamlined processes, reduced paperwork, and faster settlements
• Innovation: Opens doors for new business models and applications
