What is Blockchain?

Blockchain is a decentralized technology that enables secure, transparent, and tamper-proof transactions by recording data on a distributed ledger.

This technology serves as the foundation for cryptocurrencies like Bitcoin and Ethereum, ensuring the verification and recording of each transaction in an immutable manner.

Transactions are validated and added to a block in a sequential and chronological order through a network of connected computers, known as nodes.

Once a block is filled with transactions, it becomes part of the existing chain.

The decentralized aspect of blockchain eliminates the necessity for intermediaries, leading to reduced transaction costs and streamlined processes.

The utilization of cryptographic techniques guarantees the security of data stored on the blockchain, preventing any modifications.

Beyond cryptocurrencies, blockchain is being investigated in various sectors such as supply chain management, healthcare, voting systems, and more due to its potential to transform data management and enhance transparency.

How Does Blockchain Work?

Blockchain operates by recording transactions in a series of blocks that are linked or ‘chained’ together in chronological order, ensuring data integrity and chronological sequence.

Each block contains a list of transactions that have been verified through a process called mining.

Miners compete to solve complicated mathematical puzzles, and the first one to find the solution can add a new block to the blockchain.

Once added, the block is distributed to all the nodes in the network for validation.

Nodes, which are computers participating in the network, verify the transactions within the block before accepting it as valid.

This decentralized verification process, proposed by Satoshi Nakamoto, guarantees the security and transparency of the blockchain system.
