Through blockchain technology, IoT devices can obtain unique identity credentials, namely private key and public key pairs, enabling them to possess independence in the network. This authentication method allows each device to interact on its own behalf, achieving a decentralized network that no longer relies on traditional centralized server-client models. The decentralized network brought about by blockchain technology offers higher stability and security because hackers cannot control millions of devices by attacking a single server. Additionally, each device may be rejected by the entire network due to inability to perform the next step of interaction, thereby reducing the success rate of hacker attacks."}]}],"pr":"3218a2d051e55165276c30d129c1222cd96605c9176161e7769f15e2b489bc96"}
