Introduction
The foundation of digital currencies lies in blockchain technology, a decentralized digital ledger system (DLT) that powers Bitcoin and most cryptocurrencies. According to the Federal Reserve, blockchain combines peer-to-peer networking, distributed data storage, and cryptography to revolutionize how digital assets are stored, recorded, and transferred.
Blockchain: The Core Technology
What Is Blockchain?
Blockchain is an immutable, transparent ledger that records transactions across a network of computers. Key features include:
- Decentralization: No central authority controls the ledger.
- Security: Cryptographic hashing ensures tamper-proof records.
- Transparency: All participants can verify transactions.

How Blockchain Supports Cryptocurrencies
- Transaction Validation: Miners/validators confirm transactions via consensus mechanisms (e.g., Proof of Work or Proof of Stake).
- Smart Contracts: Self-executing agreements automate processes on platforms like Ethereum.
Types of Cryptocurrencies
1. Bitcoin (BTC)
- The first cryptocurrency, designed as a decentralized peer-to-peer cash system.
- Limited supply: 21 million coins.
2. Ethereum (ETH)
- Introduced smart contracts and decentralized applications (dApps).
- Shifting from Proof of Work to Proof of Stake (Ethereum 2.0).
3. Stablecoins
- Pegged to assets like USD (e.g., USDT, USDC) to reduce volatility.
4. Utility Tokens
- Provide access to platform-specific services (e.g., Filecoin for storage).
5. Privacy Coins
- Enhance anonymity (e.g., Monero, Zcash).
