Answer

The technical problem solved by the present invention is the problem that the donation funds in the traditional charitable donation method are unclear, which leads to the donor losing trust in the donation institution. The present invention uses blockchain technology to ensure the transparency and security of the donation information and improve the trust between the two parties.

The donation request contains the donation information of the donor, including the amount of donated materials and/or the amount of funds. For example, a donor can choose to donate 500 yuan or 100 tents.

"Pre-condition" means that the amount of materials and/or funds that can be donated in the donor's electronic wallet is greater than or equal to the amount of donated materials and/or funds requested in the donation information. The system verifies whether the balance of the electronic wallet meets the donation request.

The donation information will be written into a block, and then the block will be stored on the blockchain. Each block contains donation information and data such as timestamps, and its security is guaranteed by cryptography.

The donor's identity information will be encrypted and stored, and the corresponding block header will be generated. The block header is associated with the block containing the donation information. This method protects the privacy of the donor and can trace the donation record.

The block header stores the donor's identity information (encrypted storage) and the mapping information of the corresponding block. The mapping information can be the absolute address of the block, etc., which is used to associate the block header and the block.

The information on the blockchain is open to all nodes, and anyone can query the donation information, ensuring the transparency of the donation information. At the same time, the immutability of the blockchain also guarantees the authenticity of the information.

Third-party organizations can query the donation information disclosed on the blockchain, including the amount of donated materials and/or the amount of funds, but cannot view the identity information of the donor.

Compared with traditional charitable donation methods, the present invention uses blockchain technology to achieve decentralization, ensure the transparency, security and immutability of donation information, improve donation efficiency, and enhance the trust of donors in donation institutions.

"E-wallet" is used to record the amount of materials and/or funds to be donated, and donors can initiate donation requests through e-wallets. E-wallets can be associated with the payment account of the donor to facilitate the transfer of funds in and out.

Key Terms

Term DefinitionsBlockchainA decentralized distributed ledger technology that uses cryptographic methods to link and protect data blocks. BlockThe basic unit of the blockchain, containing transaction information, timestamps, and other relevant data. Block HeaderThe header information of each block in the blockchain, including the hash value of the block, the hash value of the previous block, and other information. Donation RequestA request initiated by the donor containing donation information. The donation information contains information such as the amount of donated materials and/or the amount of funds. E-walletAn electronic account that records the amount of materials and/or funds to be donated. Preconditions refer to the need for the donor's e-wallet balance to meet the conditions for the amount of donated materials and/or funds in the donation request. MappingThe technology that associates the block header with the block containing the donation information. Transparency refers to the fact that the information on the blockchain is open to all nodes and can be queried by anyone. Immutability refers to the fact that once the data on the blockchain is written, it cannot be tampered with, ensuring the authenticity of the data.
