Specifically, blockchain records transaction information in a ledger jointly maintained by all participants, each of which contains a series of immutable blocks. Once information is recorded in a block, it cannot be modified or deleted. In addition, blockchain adopts encryption algorithms to ensure data security, allowing only participants  with the correct keys to access and verify data on the blockchain."}]}],"pr":"693590b1f9b665df419951f900f12b81f32c9c4392ac8e3191f483dbae4e6a06"}
