BlockChain

Understanding BlockChain

BlockChain is a decentralized, distributed ledger technology that underlies cryptocurrencies like Bitcoin. It operates on a network of computers, ensuring transparency, security, and immutability. The revolutionary aspect lies in its ability to facilitate trust in a trustless environment.

Core Principles and Workings of BlockChain

At its core, BlockChain comprises a chain of blocks, each containing a cryptographic hash of the previous block. This forms a secure and unalterable record of transactions. The decentralized nature of the technology ensures that no single entity controls the entire network, enhancing security.

Decentralization and Security Features

BlockChain achieves decentralization through consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS). This not only prevents a single point of failure but also enhances security by making it computationally infeasible to alter past transactions.
