This interconnected structure ensures that once information is recorded, it cannot be altered or deleted without affecting all subsequent blocks. The resultant transparency and security make blockchain an attractive solution for numerous applications, ranging from financial services to supply chain management.

How Blockchain Works

A blockchain operates through a series of complex processes involving nodes, blocks, and chains. Here is a detailed look at these components and how they work together:

  • Nodes: These are individual computers within a blockchain network. Each node has a copy of the entire blockchain, ensuring redundancy and resilience. Nodes can independently verify and validate transactions, making the network decentralized and secure.
  • Blocks: A block is a digital record of transactions. It contains a list of recent transactions, a timestamp, and a reference to the previous block (usually in the form of a cryptographic hash). This reference forms a chain that links blocks together, ensuring that altering a single block would involve changing the entire chain, thus ensuring data integrity.
  • Chain: The chain is the sequential record of blocks. It starts with the Genesis Block, the very first block in the blockchain. As new transactions occur, they are grouped into blocks and added to the chain in a linear, chronological order, creating an unbroken chain of transaction history.

The process of adding a new block to the chain involves consensus mechanisms, such as Proof of Work (PoW) or Proof of Stake (PoS). These mechanisms ensure that all nodes in the network agree on the validity of transactions, maintaining the integrity and security of the blockchain.
