Understanding Cryptocurrencies
What are Cryptocurrencies?
Cryptocurrencies are digital or virtual currencies secured by cryptography. They operate on decentralized networks based on blockchain technology – a distributed ledger enforced by a network of computers. Unlike traditional currencies, most cryptocurrencies operate without central authority or government oversight.
Blockchain Technology
Basic Concepts
- Blockchain: Digital ledger of all transactions
- Decentralization: No central controlling authority
- Consensus: Network agreement on transactions
- Mining/Validation: Process of verifying transactions
- Smart Contracts: Self-executing digital agreements
How Blockchain Works
- Transactions grouped into blocks
- Each block linked to previous blocks
- Cryptography ensures security
- Network nodes validate transactions
- Immutable record once confirmed
