Blockchain technology is suitable for peer-to-peer (P2P) network environments, and under different deployment models such as public chains and consortium chains, it enables  functions such as consensus mechanisms, security mechanisms, storage mechanisms, P2P communication mechanisms, and smart contracts. The core value of blockchain technology lies in reducing trust costs, improving data security and transparency, and it is widely applied in fields such as finance, supply chain management, and governance."}]}],"pr":"89c7a387efe75cdb0c14ca5ad65197511db18fb8fb4caccb201613eba3033ed3"}
