Centralized Exchange (CEX)

Understanding Centralized Exchanges

Centralized exchanges (CEXs) are platforms that facilitate the trading of cryptocurrencies among users.

They maintain an order book consisting of buy and sell orders submitted by individual traders.

Using specialized software, CEXs match and execute these orders to enable transactions.

IOUs, Custody, and Trading

Unlike decentralized exchanges, CEXs do not involve direct peer-to-peer exchanges between users.

Instead, when users deposit funds onto a centralized exchange, the exchange assumes custody of the assets and provides users with IOUs.

These IOUs represent the exchange’s corresponding amount of cryptocurrency or fiat currency.

The internal accounting system of the business tracks the ownership of these IOUs as they are traded, and actual currency conversion occurs when users withdraw their funds.

Centralized exchanges have become the dominant mode of operation in the cryptocurrency industry.

They offer fast and cost-efficient transaction processing, making them popular among day traders and crypto investors seeking to buy or sell cryptocurrencies.

However, CEXs have certain drawbacks due to their reliance on a central authority:

  • Transparency: CEXs often lack transparency as they do not provide detailed information about their internal operations. This opacity can enable malicious practices such as wash trading and price manipulation.
  • Security Risks: As centralized exchanges hold custody of users’ assets, they become attractive targets for potential attacks from external hackers and insider threats within the organization.
  • Downtime and Trade Disruptions: Technical issues or coordinated attacks can result in significant downtime for CEX services. This downtime can lead to missed trading opportunities for users.
  • Government Intervention: Centralized exchanges are susceptible to government censorship and regulatory actions. Authorities can freeze or seize user funds and compel exchange operators to disclose customers’ personal information.

While centralized exchanges offer convenience and liquidity, users should be aware of these potential risks and exercise caution when using such platforms.
