The EU's proposed ban on privacy coins aims to restrict the trading of anonymous cryptocurrencies like Monero, with the core logic being to strengthen anti-money laundering regulations. Such coins achieve complete anonymity through techniques like ring signatures and zero-knowledge proofs, objectively providing a channel for financing illicit activities. If the ban is implemented, exchanges will be forced to delist privacy coins, which may cause short-term market fluctuations but will accelerate the integration of compliant crypto projects with regulatory frameworks in the long term. The point of contention is that regulators emphasize financial security, while the tech community believes that this move violates the decentralized spirit of blockchain and may push privacy technology towards more covert forms. The future struggle between regulation and privacy protection will continue to escalate.
