The Evolution of Money
Money has evolved from barter systems to commodity monies like seashells and precious metals, eventually leading to fiat currency—government-issued money backed by trust rather than intrinsic value. Modern central banks regulate money supply to maintain stability, but cryptocurrencies challenge this centralized model with decentralized, technology-driven alternatives.
Key Functions of Money:
- Store of value: Retains purchasing power over time.
- Medium of exchange: Facilitates transactions for goods/services.
- Unit of account: Measures value consistently.
How Cryptocurrencies Work
Cryptocurrencies like Bitcoin, Ethereum, and Ripple operate on distributed ledger technology (DLT), such as blockchain, eliminating the need for central intermediaries.
Blockchain Basics:
- Decentralized Validation: Network members verify transactions via cryptographic puzzles.
- Immutable Ledger: Approved transactions are added to a permanent, tamper-proof blockchain.
- Reward System: Validators (miners) earn new coins as incentives.
