Review Questions

• How does cryptocurrency function as a medium of exchange compared to traditional forms of money?
  • Cryptocurrency functions as a medium of exchange by enabling peer-to-peer transactions without the need for intermediaries like banks. This allows for faster and often cheaper transactions across borders compared to traditional money. Unlike fiat currencies, which are regulated by central authorities, cryptocurrencies operate on decentralized networks, giving users more control over their funds and reducing transaction costs associated with currency conversion.
• Discuss the role of blockchain technology in ensuring the security and integrity of cryptocurrency transactions.
  • Blockchain technology plays a critical role in securing cryptocurrency transactions by providing a decentralized ledger that records all transactions in a transparent and immutable manner. Each block in the blockchain contains a set of transactions that are cryptographically linked to previous blocks, making it nearly impossible to alter transaction history without consensus from the network. This transparency and security foster trust among users while minimizing fraud and double-spending risks.
• Evaluate the potential impact of widespread cryptocurrency adoption on traditional monetary policy and financial systems.
  • Widespread cryptocurrency adoption could significantly impact traditional monetary policy by challenging central banks' ability to control money supply and influence economic conditions. As more individuals use cryptocurrencies for transactions and savings, central banks may find it harder to implement effective monetary policy tools like interest rates. Additionally, the rise of decentralized finance (DeFi) could disrupt existing banking systems, leading to shifts in regulatory frameworks and potentially creating new financial risks that need to be addressed by policymakers.
