#加密市场回调 Recently, the U.S. Department of Justice has filed criminal charges against Chen Zhi, the founder of the Cambodian BCH Group, and has applied to confiscate 127,271 BTC under his control, valued at approximately 1.5 billion USD, making it the largest Bitcoin judicial confiscation case in the world. How could BTC, known for its anonymity and decentralization, be seized? This is different from what the public might think; the confiscation does not involve forcibly cracking the BTC algorithm. Due to the nature of the Blockchain's public ledger, every transaction can be queried and viewed. Therefore, even if the coins are dispersed to multiple addresses and then consolidated to multiple sources, it can still be traced on-chain. Being traceable on-chain allows for freezing the ability to convert it to fiat. Ultimately, judicial personnel seized the Private Key and mnemonic phrase from the criminals, thereby obtaining their "electronic signature" on-chain to complete the seizure. It can be seen that the public's impression of anonymity does not align with the actual anonymity function of BTC.
