Bitcoin is a decentralized digital currency created in 2009 by an anonymous person or group of people using the pseudonym Satoshi Nakamoto. It enables peer-to-peer transactions over the internet without the need for a central authority, using blockchain technology to ensure security and transparency.

5 Must Know Facts For Your Next Test

1. Bitcoin was the first cryptocurrency and remains the most widely recognized and valuable digital currency today, often referred to as 'digital gold'.
2. The maximum supply of Bitcoin is capped at 21 million coins, making it a deflationary asset, unlike traditional fiat currencies that can be printed without limit.
3. Transactions on the Bitcoin network are verified by miners who use computational power to solve complex mathematical problems through the proof-of-work consensus mechanism.
4. Bitcoin transactions are irreversible, meaning once a transaction is confirmed on the blockchain, it cannot be undone, which helps prevent fraud.
5. Bitcoin wallets can be hardware-based, software-based, or even paper wallets, allowing users to store their Bitcoins securely in various ways.

Review Questions

• How does Bitcoin leverage blockchain technology to enable secure peer-to-peer transactions?
  • Bitcoin utilizes blockchain technology by creating a decentralized ledger that records all transactions across a network of computers. This ledger is maintained by nodes that validate transactions using cryptographic techniques. Each transaction is grouped into blocks that are linked together in chronological order, ensuring transparency and preventing double-spending without relying on a central authority.
• Discuss the role of Bitcoin mining in the overall operation and security of the Bitcoin network.
  • Bitcoin mining is critical for the operation and security of the Bitcoin network. Miners compete to solve complex mathematical problems through a process called proof-of-work. When they successfully validate a new block of transactions, they add it to the blockchain and are rewarded with newly created Bitcoins. This process not only secures the network against attacks but also regulates the creation of new Bitcoins, contributing to its limited supply.
• Evaluate the impact of Bitcoin's maximum supply cap on its value proposition compared to traditional fiat currencies.
  • Bitcoin's maximum supply cap of 21 million coins creates scarcity, which contributes to its value proposition as a deflationary asset. Unlike traditional fiat currencies that can be printed in unlimited amounts by governments, Bitcoin's fixed supply encourages investors to perceive it as 'digital gold' and a hedge against inflation. This unique characteristic has influenced its adoption by individuals seeking an alternative store of value and has driven interest from institutional investors as part of their portfolios.
