Each block records all value exchange activities that occur within a specific time period, and each block contains an encrypted hash value pointing to the previous block. This means that each block depends on the data of the previous block, forming a chain structure. When a new block is created, it will contain  the hash value of the previous block, and simultaneously, the encrypted hash value of the current block will also be calculated. This process ensures that blocks in the blockchain are linked in chronological order, forming an immutable data structure. Nodes throughout the entire network will validate the new block, once"}]}],"pr":"4f274cdd407a81929422eb07c36f63dc3f8d1be4d21ae04d5e1b6d6a918c8d9a"}
