Blockchain: Introduction to Blockchain: Blockchain is a decentralized, distributed digital ledger technology that records transactions across many computers so that the recorded data cannot be altered retroactively. It was first conceptualized as the underlying technology behind Bitcoin, but it has since evolved to support various use cases beyond cryptocurrencies. Overview of Blockchain: A blockchain consists of blocks (groups of transactions) linked in a chain in a chronological order. Each block contains a timestamp, transaction data, and a reference to the previous block (the hash). Blockchain operates in a peer-to-peer network, where each participant holds a copy of the entire blockchain. Transactions are verified using consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS). The decentralized nature of blockchain ensures transparency, security, and immutability. Features of Blockchain: Decentralization: No single entity has control over the block...
