In the data layer, blockchain stores data in individual blocks, which are linked to form a chain-like data structure through hash links. The network layer is responsible for handling communication issues in P2P networks, achieving information transmission between nodes. The consensus layer  implements consensus mechanisms in blockchain networks to ensure data consistency and security. Nodes in the entire blockchain network jointly participate in data verification and maintenance, realizing decentralization and open transparency. In addition, blockchain can be divided into public chains, private chains, and consortium chains according to different application scenarios."}]}],"pr":"bde873ac71bd68da04c9204492ced69f666168208791b9bb22a6b6c3d9325255"}
