- Secure: Uses cryptographic techniques to secure transactions and control the creation of new units.
- Peer-to-peer: Enables direct transactions between users without middlemen.
- Blockchain Ledger: All transactions are recorded on a blockchain, a public, distributed ledger that is maintained by a network of computers (nodes). Each transaction is verified and grouped into a block.
- Transactions use cryptographic keys: Public keys act as addresses that others can send cryptocurrency to.Private keys are secret and prove ownership, enabling users to sign transactions securely.
- Mining and Validation: For many cryptocurrencies like Bitcoin, new transactions are validated by “miners” who solve complex mathematical problems to add blocks to the blockchain. This process ensures trust and security.
- Wallets: Cryptocurrency wallets store private and public keys, enabling users to send, receive, and manage their digital assets.
- Bitcoin (BTC): The first and most well-known cryptocurrency, created as a decentralized alternative to traditional money.
- Altcoins: Other cryptocurrencies developed after Bitcoin, often with improvements or new features.
- Ethereum (ETH): Enables smart contracts and decentralized applications (dApps).
- Ripple (XRP): Focused on fast cross-border payments.
- Litecoin (LTC), Cardano (ADA), Polkadot (DOT): Each with unique consensus mechanisms or use cases.
- Stablecoins: Cryptocurrencies pegged to stable assets like USD to reduce volatility.
- Tokens: Digital assets issued on existing blockchains (like Ethereum) to represent various assets or utilities.
- Decentralized Network: Nodes around the world maintain copies of the ledger, preventing central points of failure.
- Immutability: Once recorded, transactions cannot be altered without consensus, preventing fraud.
- Consensus Protocols: Mechanisms like Proof of Work (PoW) or Proof of Stake (PoS) ensure all nodes agree on the ledger’s state.
- Transparency: All transactions are visible on the blockchain, enhancing trust.
- Lower Transaction Fees: Without intermediaries, transaction fees are often significantly lower than traditional banking or payment systems.

- Security Risks: Though secure, crypto wallets and exchanges can be vulnerable to hacking if not properly managed.
- Scams and Fraud: The crypto space has seen scams and fraudulent projects, requiring caution from investors.
- Technical Complexity: For many users, the technology behind cryptocurrency remains complex and challenging.
- Mainstream Adoption: More businesses and individuals are using cryptocurrencies for payments and investment.
- Central Bank Digital Currencies (CBDCs): Governments are exploring digital versions of fiat money that could integrate with or compete against cryptocurrencies.
- DeFi and NFTs: Decentralized finance and non-fungible tokens are expanding cryptocurrency’s utility beyond payments.
- Improved Scalability: New blockchain designs aim to handle more transactions faster and cheaper.
