Firstly, blockchain adopts a decentralized architecture, distributing data across multiple nodes in the network, each of which saves a complete blockchain ledger. When new transactions occur, nodes need to reach a consensus to verify the validity of the transactions. This process involves the application of cryptographic technologies, such as asymmetric encryption algorithms and hash algorithms.\n\nAsymmetric encryption algorithms are used  to ensure secure communication between nodes, making it difficult for the communication process to be tampered with or eavesdropped on. Hash algorithms are used to generate fingerprints of data, mapping transaction data into a fixed"}]}],"pr":"2a7fed7aa49841a9e734c487e65b0ef8cdbc1763a8dc958860c447cee1cd1e44"}
