Each node contains a hash value, and the connection between nodes represents the dependency relationship between transactions. When  a new transaction is added to the block, its hash value is calculated and inserted into the corresponding position in the Merkle tree. Thus, each block has a unique Merkle root hash value representing the collection of all transactions in that block."}]}],"pr":"b18920ea5e4745728665cc91516571232e2a8c2e7d3f32f92557ee5e2aafa3d7"}
