Cryptocurrency and blockchain technology

1. Introduction

1. Cryptocurrency is a digital or virtual currency that uses cryptography for security.
2. Unlike traditional currencies, cryptocurrencies operate on a decentralized network using blockchain technology.
3. Bitcoin, introduced in 2009, was the first cryptocurrency and remains the most well-known.
4. Blockchain is a distributed ledger technology (DLT) that ensures transparency and security through immutable records.

2. Features of Cryptocurrency

1. Decentralized: Operates without a central authority like a bank or government.
2. Peer-to-peer transactions: Allows direct transfers between users without intermediaries.
3. Secure: Uses cryptographic algorithms to protect transactions and user identities.
4. Global accessibility: Transactions can occur anywhere in the world.
5. Limited supply: Many cryptocurrencies have a cap, e.g., Bitcoin has a limit of 21 million coins.

3. Uses of Blockchain Technology

1. Cryptocurrencies: Facilitates secure and transparent digital currency transactions.
2. Smart contracts: Self-executing contracts with terms directly written into code.
3. Supply chain management: Tracks the origin and movement of goods to ensure authenticity.
4. Healthcare: Protects patient records and ensures data privacy.
5. Voting systems: Provides secure and tamper-proof voting mechanisms.

4. Advantages of Cryptocurrency

1. Lower transaction costs: Eliminates the need for intermediaries.
2. Increased financial inclusion: Provides access to banking for unbanked populations.
3. Transparency: Blockchain ensures open and verifiable transactions.
4. Enhanced security: Resistant to fraud and hacking due to cryptographic techniques.
5. Facilitates cross-border transactions without currency exchange issues.

5. Challenges of Cryptocurrency

1. Volatility: Prices can fluctuate drastically, making it a risky investment.
