Each block contains a hash value, which is used to link the previous block, forming a chain-like structure. This chain-like structure enables tampering with a single block  to be detected, as any changes made to the block would cause the hash value to change, making it impossible to link it to the previous block."}]}],"pr":"88fb7d68007751be6520cc930bdea8ad003f9fd995f32e0685a3630227a4e427"}
