币界网报道：German financial regulator BaFin has launched an investigation into DeepSeek, a blockchain analytics firm, over potential violations of data privacy laws. The probe focuses on whether the company improperly collected and processed personal data through its on-chain surveillance tools. BaFin officials expressed concerns that DeepSeek's technology, which tracks cryptocurrency transactions across multiple blockchains, may have exceeded legal boundaries in its data gathering practices. The regulator is particularly examining if the firm obtained proper consent from individuals whose transaction data was analyzed. DeepSeek claims its services help combat financial crimes by providing compliance solutions to crypto businesses and law enforcement agencies. However, privacy advocates argue such extensive blockchain monitoring raises significant civil liberties issues. The investigation comes as EU lawmakers debate stricter regulations for crypto surveillance tools under the upcoming Markets in Crypto-Assets (MiCA) framework. DeepSeek stated it is fully cooperating with authorities and maintains its operations comply with all applicable laws. Industry analysts suggest this case could set important precedents for how privacy laws apply to blockchain analytics in Europe.
