Bitcoin is the world's first successful decentralized cryptocurrency and payment system, launched in 2009 by an anonymous creator known as Satoshi Nakamoto. It operates on a peer-to-peer network, allowing users to exchange value directly without the need for intermediaries like banks.

Key Features of Bitcoin

  • Decentralization: Bitcoin is not controlled by any central authority, making it resistant to censorship and manipulation.
  • Blockchain Technology: Transactions are recorded on a public ledger called the blockchain, ensuring transparency and security.
  • Limited Supply: The total supply of Bitcoin is capped at 21 million coins, which helps to maintain its value over time.
  • Divisibility: Bitcoin can be divided into smaller units called satoshis, allowing for microtransactions.

How Bitcoin Works

Bitcoin transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. The process of adding transactions to the blockchain is known as mining, which involves solving complex mathematical problems.

Sample Code for a Simple Bitcoin Transaction


    const bitcoin = require('bitcoinjs-lib');
    const network = bitcoin.networks.bitcoin;

    // Create a new key pair
    const keyPair = bitcoin.ECPair.makeRandom({ network });

    // Get the public key in a readable format
    const { address } = bitcoin.payments.p2pkh({ pubkey: keyPair.publicKey, network });

    console.log('Bitcoin Address:', address);

How to Obtain Bitcoin

  • Buying: You can purchase Bitcoin through various cryptocurrency exchanges using fiat currency.
  • Mining: Bitcoin can be mined by solving complex mathematical problems, which requires significant computational power.
  • Transferring: Bitcoin can be transferred from one wallet to another, similar to sending digital cash.

Advantages and Disadvantages of Bitcoin

Advantages

  • Decentralized and secure.
  • Lower transaction fees compared to traditional banking.
