First, a block chain technology is briefly introduced, wherein the block chain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc., and is essentially a de-mediated database, and meanwhile, as a bottom layer technology of bitcoin, the block chain is a series of data blocks which are associated and generated by using a cryptographic method, and each data block contains information of one bitcoin network transaction, which is used for verifying the validity (anti-counterfeiting) of the information and generating the next block. The multi-node backup feature of the blockchain ensures that any one node in the blockchain network is alive.
Exemplary donation demand data may include: for example, in the first central hospital department of city a, patient B cannot continue to pay the hospitalization cost due to difficulty in family conditions, and needs social donation of 2 ten thousand yuan first. In this specific example, the donation item information is hospitalization cost, the donation amount demand information is 2 ten thousand yuan, the donation use information is treatment, and the donated person information is related information of the patient B, such as family address, work unit, birth year and month, family condition, and the like; the donations are money.

S140, carrying out Hash encryption on the encrypted donation data information and the actual donation amount information to generate a donation digital certificate, and issuing the donation digital certificate to the donator, wherein the donation detail information is inquired through the donation digital certificate.
Where Hash, transliterated as "Hash," refers to the transformation of an input of arbitrary length into a fixed length output, i.e., a Hash value, by a hashing algorithm, the transformation is a compression mapping, i.e., the space of a Hash value is usually much smaller than the space of an input, different inputs may Hash to the same output, so it is not possible to determine a unique input value from a Hash value. In short, it is a function of compressing a message of an arbitrary length to a message digest of a certain fixed length.
Specifically, after the donation action of the donator occurs, actual donation amount information is added to the donated data information after encryption, and data corresponding to the actual donation amount information of the data amount corresponding to the donated data information is spliced. The data after splicing is subjected to Hash encryption, so that the safety of donation information is ensured. The donation data information comprises donation time information, donator information, donation item information, donation amount demand information, donation use information, donator information and donation information.
