It has significant advantages in areas such as cybersecurity, data traceability, and supply chain management. Through distributed node storage and encryption technology, blockchain can ensure the secure transmission and storage of data, effectively preventing data breaches and tampering. In addition, the transparency and immutability of  blockchain make any suspicious activities promptly detectable, thereby improving the overall security of the system.\n\nHowever, blockchain is not absolutely secure. It also poses certain potential risks, such as technical vulnerabilities and smart contract risks. These risks can be gradually reduced by continuously upgrading technology, improving protocols, and strengthening regulation."}]}],"pr":"067a778e640182e65fa083cf8b35eb4bf31e173a82fa567da0e782e80acc9238"}
