중앙화 거래소 (CEX)
사용자 자금을 수탁하고 중앙 주문서를 통해 매수/매도 주문을 매칭하는 기업 운영 암호화폐 거래소.
주요 CEX: Binance, Coinbase, Kraken, OKX. 수익: 거래 수수료(0.1–0.5%), 스프레드, 상장 수수료. CEX vs DEX: CEX — 높은 유동성, 법정화폐 지원, 하지만 수탁 위험.

🧒 5살도 이해할 수 있게 설명
[CEX](/ko/terms/cex)는 은행과 증권 거래소를 합친 것과 같지만 암호화폐용입니다. 비트코인을 맡기면 거래 플랫폼에서 사고팔 수 있습니다. 문제는 '은행'이 파산하면 돈이 사라질 수 있다는 것 — 2022년 FTX가 바로 그 사례입니다.

❓ 자주 묻는 질문
What is the main risk of using a CEX?
Custodial risk: you do not control your private keys. If the exchange is hacked, goes bankrupt (like FTX in 2022), or freezes withdrawals, you may lose access to your funds.
What is Proof-of-Reserves?
A Proof-of-Reserves (PoR) is a cryptographic attestation that a CEX actually holds the assets it claims to hold for users. After FTX collapsed, it became a standard practice for exchanges to publish Merkle-tree-based PoR reports. However, PoR only proves assets, not liabilities.
What is the difference between a maker and a taker on a CEX?
A market maker places a limit order that sits on the order book, adding liquidity. A taker executes against an existing order, removing liquidity. Makers typically pay lower fees than takers.
