Understanding Blockchain: How It Works and Its Key Features

Blockchain functions on a fundamental principle: a distributed ledger that is both unchangeable and transparent. Each block in the blockchain contains a number of transactions. Every time a new transaction is carried out, it is encrypted and added to a block. Once a block is filled with transactions, it is closed and linked to the preceding block, forming a chain.

One of the key features of blockchain technology is its decentralization. Unlike traditional databases that store data in a centralized location, blockchain data is copied and spread across a network of computers. When a new block is added, each copy of the blockchain is updated simultaneously. This consensus mechanism ensures that each copy of the distributed ledger is identical and accurate.

Another defining characteristic of blockchain is its immutability. Once a block is added to the chain, it becomes very difficult to alter. This immutability is safeguarded by cryptographic hash functions, which secure the blocks and their contents, and by the network agreement, which means that the majority of the nodes must concur on a new block's validity before it is added to the ledger.

Blockchain's features, including its security and transparency, are driving innovation in fields as diverse as logistics, finance, and intellectual property. These features ensure that all participants in the network can trust the validity of transactions without the need for an intermediary, such as a bank or other central authority.
