Holy crap! Binance's user system is having another problem! What's the difference between Binance, the world's largest exchange, and the world's largest bank, the Industrial and Commercial Bank of China (ICBC)? Recently, Binance experienced a "user ID clash": Binance US, Binance Thailand, and Binance France each had a user with the UID 123456. The official explanation is compliant: they are independent entities with separate account systems. But users aren't buying it. Subconsciously, they believe "Binance is a unified entity," so entering the UID for transfers is perfectly normal, yet their money was lost. What about ICBC? With branches in dozens of countries and regions worldwide, would users have the same user ID? The answer might surprise you: In multinational financial groups, inconsistent or even identical customer IDs across different countries are actually common industry practice. Therefore, it's quite normal for ICBC's global user IDs and Binance's user IDs to clash. There are three reasons: First, the law doesn't allow for uniformity. Multinational banks must comply with local KYC rules and data privacy laws in each country. The same customer may receive completely different ID formats in different countries. Forcing a single ID to work globally is legally unfeasible. Second, ICBC relies on "logical consistency," not "forced ID generation." ICBC developed its own FOVA global technology platform, allowing customers to "uniformly query" global accounts on online banking, but the underlying physical accounts remain decentralized. Third, banks have "physical safeguards." ICBC will never allow you to transfer funds across borders using only an "ICBC ID." Cross-bank transfers require the complete account number, account name, and SWIFT code. This hard isolation directly eliminates the risk of duplicate IDs. So the truth is: Binance's independent account system is not flawed; the problem lies in the lack of a safeguard in its product design. It doesn't forcibly block the dangerous action of "entering a UID for cross-site transfers." ICBC has safeguards, Binance doesn't. That's the difference. @heyibinance
