Although  blockchain technology is decentralized and secure, privacy challenges still exist in some scenarios. For example, transaction records and participant identity information on the blockchain are public, which may lead to user privacy leaks. However, with the development of technologies such as zero-knowledge proof (ZKP) and secure multiparty computation, the privacy protection capabilities in the blockchain field have been enhanced. Many blockchain projects, such as Ethereum's ZK-Rollup, are applying these technologies to improve privacy protection levels. In summary, although blockchain technology has certain problems in privacy protection, continuous optimization can address these issues."}]}],"pr":"9e8486e32f3cdaa8542110cf86f3a277ac89963cebba7b1adc3bf277b0cf4278"}
