币界网报道：German scholars found that stablecoin payments pose serious privacy risks. In December 2024, three German marketing professors successfully reconstructed a complete customer profile of eight direct-to-consumer brands by analyzing 22.7 million retail stablecoin transaction data. The study revealed multiple privacy risks brought about by the popularity of stablecoins, including salary information leakage, personal privacy damage, and commercial competitive intelligence leakage. Experts warned that as the scale of stablecoin payments continues to expand, these privacy issues will become increasingly serious, and it is recommended to implement effective privacy protection measures as soon as possible before the cost of transparent taxes is too high.
