🔧 Essential Crypto Terminology
Beyond slang, understanding core blockchain terminology is crucial for deeper engagement.
1. Fiat Currency
Government-issued money like USD or CNY, not backed by physical commodities but by trust in the issuing authority.
2. Stablecoins
Cryptocurrencies pegged to stable assets like the US dollar. Examples include USDT, USDC, and DAI—ideal for reducing volatility in trading.
3. Smart Contracts
Self-executing contracts coded on blockchains like Ethereum. They run automatically when predefined conditions are met—no intermediaries needed.
4. CEX vs DEX
- CEX (Centralized Exchange): Platforms like Binance or OKX that act as trusted third parties for trading.
- DEX (Decentralized Exchange): Peer-to-peer platforms like Uniswap where users trade directly via smart contracts.
5. Public Chain (公链)
Open blockchains like Ethereum, Solana, or Cosmos where anyone can participate in validation, send transactions, or build applications.
6. Seed Phrase (注记词)
A set of 12–24 words generated when creating a crypto wallet. It acts as the master key—losing it means losing access to your funds forever.
7. Mainstream Coins vs Altcoins
- Mainstream Coins: Top-tier cryptocurrencies like BTC, ETH, BNB—high liquidity and wide adoption.
- Altcoins: All other tokens outside Bitcoin and sometimes Ethereum; includes speculative assets.
8. C2C & OTC Trading
- C2C (Customer-to-Customer): Direct peer-to-peer trades on exchange platforms using local payment methods.
- OTC (Over-the-Counter): Large-volume trades conducted privately between buyers and sellers, often used to avoid slippage.
9. Token Burning

10. Airdrop
Free distribution of tokens or NFTs to wallet addresses, usually to reward early adopters or promote new projects.
11. DeFi (Decentralized Finance)
Financial services built on blockchain without intermediaries—lending, borrowing, staking, and yield farming all happen through smart contracts.
12. Liquidity Pool (LP)
Funds locked in a smart contract to facilitate trading on DEXs. Providers earn fees based on their share of the pool.
13. ICO / IEO / IDO
- ICO (Initial Coin Offering): Public fundraising via token sales.
- IEO (Initial Exchange Offering): Token sale hosted directly on a centralized exchange.
- IDO (Initial DEX Offering): Launch of a new token on a decentralized exchange after vetting.
14. Private & Public Sale (私募 / 公募)
- Private Sale: Early fundraising round for select investors at discounted rates.
- Public Sale: Open token sale accessible to everyone on a platform.
15. Proof-of-Work (PoW) vs Proof-of-Stake (PoS)
- PoW: Miners compete to solve complex puzzles (e.g., Bitcoin). Energy-intensive but secure.
- PoS: Validators are chosen based on how many coins they stake (e.g., Ethereum post-Merge). More energy-efficient.
16. Layer 1 vs Layer 2
- Layer 1: The base blockchain (e.g., Ethereum). Focuses on security and decentralization.
- Layer 2: Secondary protocols built on top (e.g., Arbitrum, Optimism) to improve speed and lower fees.
17. Zero-Knowledge Proof
