As a specialized distributed database, blockchain adopts a decentralized architecture, storing and synchronizing data across multiple nodes, ensuring the integrity and traceability of the data. Blockchain technology uses asymmetric cryptography to encrypt the data, and leverages the strong computing power formed  by consensus algorithms such as node workload proof in distributed systems to resist external attacks, thereby ensuring the tamper-proof and fraud-proof nature of the data. Therefore, blockchain technology has significant advantages in preventing data fraud."}]}],"pr":"4657662fb423046538ae6ebe2b52dce763521f785ee7932210b7dfa4373a1723"}
