The system related to the embodiment of the present disclosure may be a blockchain system formed by connecting a client, a plurality of nodes (any form of computing devices in an access network, such as servers and terminals) through a network communication mode.

Taking a distributed blockchain system as an example, referring To fig. 1, fig. 1 is an optional structural schematic diagram of a blockchain system 100 provided in the embodiment of the present disclosure, and is formed by a plurality of nodes 200 (any form of computing devices in an access network, such as servers and terminals) and a client 300, a Peer-To-Peer (P2P, Peer To Peer) network is formed between the nodes 200, and the P2P Protocol is an application layer Protocol operating on a Transmission Control Protocol (TCP). In a blockchain system, any machine, such as a server, a terminal, can join to become a node 200, and the node 200 includes a hardware layer, an intermediate layer, an operating system layer, and an application layer.

Referring to fig. 1, the functions of each node 200 in the blockchain system 100 are shown, and the functions involved include:

1) routing, a basic function that node 200 has, is used to support communication between nodes 200.

Besides the routing function, the node may also have the following functions:

2) the application is used for being deployed in a block chain, realizing specific services according to actual service requirements, recording data related to the realization functions to form recording data, carrying a digital signature in the recording data to represent a source of task data, and sending the recording data to other nodes in the block chain system, so that the other nodes add the recording data to a temporary block when the source and integrity of the recording data are verified successfully.

For example, the services implemented by the application include:

2.1) wallet, for providing the function of transaction of electronic money, including initiating transaction (i.e. sending the transaction record of current transaction to other nodes in the blockchain system, after the other nodes are successfully verified, storing the record data of transaction in the temporary blocks of the blockchain as the response of confirming the transaction is valid; of course, the wallet also supports the querying of the electronic money remaining in the electronic money address.

And 2.2) sharing the account book, wherein the shared account book is used for providing functions of operations such as storage, query and modification of account data, record data of the operations on the account data are sent to other nodes in the block chain system, and after the other nodes verify the validity, the record data are stored in a temporary block as a response for acknowledging that the account data are valid, and confirmation can be sent to the node initiating the operations.

2.3) Intelligent contracts, computerized agreements, which can enforce the terms of a contract, implemented by codes deployed on a shared ledger for execution when certain conditions are met, for completing automated transactions according to actual business requirement codes, such as querying the logistics status of goods purchased by a buyer, transferring the buyer's electronic money to the merchant's address after the buyer signs for the goods; of course, smart contracts are not limited to executing contracts for trading, but may also execute contracts that process received information.

3) And the Block chain comprises a series of blocks (blocks) which are mutually connected according to the generated chronological order, new blocks cannot be removed once being added into the Block chain, and recorded data submitted by nodes in the Block chain system are recorded in the blocks.

Referring to fig. 2, fig. 2 is an optional schematic diagram of a Block Structure (Block Structure) provided in the embodiment of the present disclosure, where each Block includes a hash value of a transaction record stored in the Block (hash value of the Block) and a hash value of a previous Block, and the blocks are connected by the hash values to form a Block chain. The block may include information such as a time stamp at the time of block generation. A block chain (Blockchain), which is essentially a decentralized database, is a string of data blocks associated by using cryptography, and each data block contains related information for verifying the validity (anti-counterfeiting) of the information and generating a next block.

Based on the technical problems in the related art, the embodiments of the present disclosure provide a method for processing donation data based on a block chain, so as to at least partially solve the above problems. The method provided by the embodiments of the present disclosure may be executed by any electronic device, for example, a server, or any one or more of terminals, or an interaction between a server and a terminal, which is not limited by the present disclosure.

When the embodiment of the present disclosure is implemented by using a Cloud technology (Cloud technology), the server may also be a Cloud server that provides basic Cloud computing services such as a Cloud service, a Cloud database, Cloud computing, a Cloud function, Cloud storage, a Network service, Cloud communication, a middleware service, a domain name service, a security service, a CDN (Content Delivery Network), and a big data and artificial intelligence platform.

The cloud technology is based on the general names of network technology, information technology, integration technology, management platform technology, application technology and the like applied in the cloud computing business model, can form a resource pool, is used as required, and is flexible and convenient. Cloud computing technology will become an important support. Background services of the technical network system require a large amount of computing and storage resources, such as video websites, picture-like websites and more web portals. With the high development and application of the internet industry, each article may have its own identification mark and needs to be transmitted to a background system for logic processing, data in different levels are processed separately, and various industrial data need strong system background support and can only be realized through cloud computing.

The terminal may be, but is not limited to, a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, and the like. The terminal and the server may be directly or indirectly connected through wired or wireless communication, and the application is not limited herein.

Fig. 3 schematically shows a flow chart of a block chain-based material donation data processing method according to an embodiment of the present disclosure. As shown in fig. 3, the method provided by the embodiment of the present disclosure may include the following steps.

In step S310, donor data sent by a donor node of a target federation chain and public institution data sent by a public institution node of the target federation chain are received by a consensus node of the target federation chain.

In conjunction with fig. 1 and 4, the block chain system 100 shown in fig. 1 may include a plurality of federation chains, and any one of the plurality of federation chains may be used as the target federation chain 100-1. The alliance chain only allows authorized nodes to join a network aiming at members of a certain group and limited third parties, information can be viewed according to authority, the alliance chain is often used for a block chain among organizations, a plurality of preselected nodes are designated as bookkeepers in the block chain, and generation of each block is determined by all the preselected nodes together.

In the embodiment of the present disclosure, the target federation chain 100-1 is applied to the processing of material donation data, which authorizes a node of a public interest participant in a certain region to join the network of the target federation chain 100-1, for example, assuming that each federation chain is divided into regions with a certain level of administration, such as a donator, charitable organization, logistics party, warehousing party, regulatory agency in a certain province or a certain city, and the like, is authorized to join the target federation chain 100-1. The blockchain system that includes the target federation chain 100-1 can be referred to as a public interest federation chain.

In the following description, it is exemplified that each alliance chain in a public welfare alliance chain is divided at provincial level, that is, a supervising and supervising function for data donation can be implemented by taking a supervising and supervising authority in each province, for example, a civil office in each province as a common node in an alliance chain corresponding to the province, each alliance chain corresponding to each province has its own relatively independent public welfare chain shared account book, for example, a target alliance chain has a target public welfare chain shared account book, each donator, common node, public welfare agency node (for example, may further include charity organization node, logistics node, warehousing party node, etc.), a material issuing agency node, donator node, etc., can only obtain the target public welfare chain shared account book corresponding to the target alliance chain, but cannot obtain the public welfare chain shared account book of another province, therefore, the hierarchical processing of the material donation data is realized, namely, the sharing of the material donation data in the same alliance chain is realized, the independence of the material donation data in different alliance chains is realized, and the confidentiality and the safety of the material donation data are guaranteed.

In the above example, although each federation chain is divided by provinces, the geographical locations of the donor node, the public institution node, the material issuing institution node, the donor node, and the like in each federation chain are not limited to the provinces of the corresponding federation chain. For example, a province alliance chain is constructed by taking a civil office of province a as an consensus node, and the consensus node of the province alliance chain is used for performing consensus on the material donation data in province a and sharing the common earnings to the public welfare chain in province a. The charitable organization of province A authorizes and joins the alliance chain network of province A to become one charitable organization node, the charitable organization of province A can select the logistics party and the warehousing party of province B to serve as the cooperative logistics party and the cooperative warehousing party, so that the charitable organization of province A transports and stores the received donated materials to a certain warehouse of province B, and the logistics party and the warehousing party of province B can be authorized and joined into the alliance chain of province A to become the logistics party node and the warehousing party node of province A. Each node in province a can only read and view the material donation data on the public welfare chain shared ledger in province a.

Similarly, the donor and the recipient in the same federation chain may be in different provinces, i.e., cross-domain interworking may be achieved.

For example, as shown in fig. 4, taking target federation chain 100-1 as an example, assume that a regulatory agency in the province (such as a civil hall in the province, but the disclosure is not limited thereto) maps to a consensus node 200-5 in the target federation chain 100-1 through its corresponding server 400 (illustrated here as a server, but a terminal may also be used in practice).

The donor (which may be an individual or an enterprise or public institution, etc.) inputs donor data through a client (which may be any client capable of realizing material donation) 300-1 installed on a terminal of the donor, transmits the input donor data to the donor node 200-1 mapped in the target federation chain 100-1 through the terminal of the donor, and the donor node 200-1 transmits the received donor data to the consensus node 200-5 in the target federation chain 100-1.

In the embodiment of the present disclosure, the donor data may include donor information, donor donation material information, and donor signature.

If the donor is an individual, the donor information may include any one or more of the name, contact address (e.g., mobile phone number, email address, and residence address), identification number, and the like of the donor. If the donor is an enterprise, the donor information may include, for example, any one or more of a unit name, an organization code, a corporate representative, a business license, etc. of the donor.

The donator material information refers to donation material related data reported by the donator, for example, related data such as the type, name, quantity, volume, size, function and usage of donated materials may be donated, and the donator material information may further include which public welfare institution the donated materials are donated to, that is, public welfare institution information.

It is understood that the donation materials mentioned in the embodiments of the present disclosure may be physical materials, such as clothes of an entity, books of the entity, and the like, or virtual materials, such as money, virtual commodities, and the like, and the present disclosure does not limit the present disclosure.

In the embodiment of the present disclosure, in order to obtain authorization to enter the target federation chain 100-1 network, a donor may apply a digital Certificate to an Authority CA (Certificate Authority) to identify the identity of the donor, which is referred to as a donor Certificate.

When the donor reports the donor data through the client 300-1, the donor can sign the donor information and the donor donation material information of the uplink (to be written into the target alliance chain) with the private key information corresponding to the donor certificate, generate a donor signature, and send the donor information, the donor donation material information and the donor signature together as the donor data to the consensus node 200-5.

In an exemplary embodiment, the public institution data may include public institution information, public institution donation material information, and public institution signatures.

The public service institution information may include any data related to the public service institution, such as a name, a code, and the like of the public service institution. The donation material information of the public institution may include any data related to donation materials reported by the public institution after receiving the donation materials from the donator, for example, related data such as the type, name, quantity, volume, size, function and usage of the donation materials received by the public institution. To gain authorization to access the target federation chain 100-1 network, the public institution may apply a digital Certificate, referred to as a public institution Certificate, to an authoritative CA (Certificate Authority) for identifying the identity of the public institution. When the public welfare agency reports the public welfare agency data through the client of the public welfare agency, the public welfare agency information and the public welfare agency donation material information which are to be linked (the public welfare agency data are to be written into a target alliance chain) can be signed by using the private key information corresponding to the public welfare agency certificate, a public welfare agency signature is generated, and the public welfare agency information, the public welfare agency donation material information and the public welfare agency signature are used as public welfare agency data to be sent to the common recognition node 200-5.

When the donated materials are received as physical objects, especially when a large number of physical objects are received, the public institution generally needs to jointly implement services such as receiving, transporting, storing and the like of the donated materials by means of logistics and warehousing. Therefore, in the following description, the public institution including the corresponding charitable organization, the logistics party (which may be referred to as the determined cooperative logistics party) and the warehousing party (which may be referred to as the determined cooperative warehousing party) is taken as an example for illustration, but the disclosure is not limited thereto, and in some cases, the donated materials may be directly distributed to the donated persons by the public institution such as the charitable organization itself, or the donated materials may be distributed to the donated persons by the charitable organization and the cooperative logistics party, or the donated materials may be distributed to the donated persons by the charitable organization and the cooperative warehousing party, which is not limited by the disclosure.

Taking the example of a public welfare agency including a charitable organization, a corresponding logistics party (a partner logistics party), and a corresponding warehousing party (a partner warehousing party), the public welfare agency data may include charitable organization data, logistics party data, and warehousing party data, and the public welfare agency nodes of the target federation chain 100-1 may include the charitable organization nodes 200-2, the logistics party nodes 200-3, and the warehousing party nodes 200-4 of the target federation chain 100-1.

The donated data may include, among other things, a donated party ID, a material ID, donated party information, a donated party certificate, and a donated party signature. If the donated party is an individual, the information of the donated party may include related information such as name, contact address, etc. of the donated party, and if the donated party is an enterprise, the information of the donated party may include related information such as name, organization code, contact address, office address, etc. of the donated party.

In step S350, the material distribution data and the donated data are successfully verified by the consensus node of the target alliance chain, a logout operation is performed on the material certificate, and the logout operation is recorded to the target public welfare chain shared account book.

In the embodiment of the present disclosure, after receiving the material distribution data and the donated data, the consensus node 200-5 of the target federation chain 100-1 may verify a charitable organization signature in the material distribution data, verify a donated party signature in the donated data, further perform cross verification on the material distribution data and the donated data if both signatures pass verification, and determine that the material distribution data and the donated data are successfully verified if information of charitable organization, which donated party is distributed, what is distributed, and how much donated material is given to the donated party, which partner logistics party transports the donated material, which partner warehouse obtains the donated material, and the like in the material distribution data can be consistent with data reported by the donated party.

As shown in fig. 7, after the donated data is successfully verified, the donated data may be linked, that is, the common nodes of the target federation chain are sorted according to the time stamp of the donated data and then packed into a certain block, and then stored into the target public welfare chain shared account book, where the data structure on the chain may include a sixth key and a sixth key value, the sixth key may be the donated party ID, and the sixth key value may include the material ID, the donated party information, the donated party certificate, and the donated party signature.

At this time, the process of donating the material this time is completed completely, the consensus node may execute an operation of deregistering the corresponding material credential, and record the deregistration operation on the target commonweal chain shared ledger, so that each node in the target alliance chain 100-1 knows that the donation of the material this time has been completed successfully, for example, the state of the material credential originally stored in the target commonweal chain shared ledger may be updated, and the state is marked as "deregistered".

In an exemplary embodiment, the method may further include: uploading the target public welfare chain shared account to a consensus node of a public welfare alliance chain, wherein the public welfare alliance chain comprises the target alliance chain.

As shown in fig. 5, the public welfare alliance chain constructed in the embodiment of the present disclosure may further include a national-level department of civil affairs as a core regulatory agency, where the core regulatory agency serves as a consensus node of the public welfare alliance chain and may receive public welfare chain shared accounts uploaded by the consensus nodes in the alliance chains from various provinces, including the target public welfare chain shared accounts uploaded by the target alliance chain. Like this, the public welfare chain sharing account book of each province can be gathered to the formula node of the core regulatory agency of national level, has guaranteed the privacy nature of data is donated to the goods and materials promptly, also can realize unified supervision.

The method for processing data donation of goods and materials based on block chain provided by the embodiment of the present disclosure builds a target alliance chain by adopting an alliance chain technology in the block chain technology, wherein the target alliance chain comprises a consensus node, a donor node, a public institution node, a goods and materials issuing institution node and a donated node, on one hand, the consensus node of the target alliance chain receives the donor data sent by the donor node of the target alliance chain and the public institution data sent by the public institution node of the target alliance chain, and also can receive the goods and materials distribution data sent by the goods and materials issuing institution node of the target alliance chain and the donated data sent by the donated node of the target alliance chain, so as to ensure that the data reporting main body of each link participating in the goods and materials donation leaves a mark on the right of the data ownership thereof, so that the reporting process can be traced and the data can be prevented from being tampered, the credibility of the data is ensured; on the other hand, when the data of the donator and the data of the public institution are successfully verified through the consensus node of the target alliance chain, a material certificate is generated and stored in the target public institution chain shared account book of the target alliance chain, so that the data of the donation of the material can be shared between institutions or users participating in each link of the donation of the material in time, the transparency of the data of the donation of the material is improved, the data of the donation of the material can be effectively monitored, and the data of the donation of the material can be used for realizing the cooperation between large-scale institutions and organizations.

As shown in fig. 5, a public welfare alliance chain network in which each supervising authority and each local donor, charity, warehouse, logistics and donator are interconnected and intercommunicated across domains is constructed by using Fabric of hyperleeder (hyper book) as a network bottom engine of a block chain system. The method is constructed by using a Fabric network under the Kafka consensus algorithm.

For example, the commonweal participant nodes of the target federation chain are assumed to include a donor, a charitable organization, a logistics party (a partner logistics party), a warehousing party (a partner warehousing party), and a donor recipient. The donator, the charitable organization, the logistics party, the warehouse party and the donator call corresponding donator nodes, charitable organization nodes, logistics party nodes, warehouse party nodes and donator nodes on the target alliance chain through clients installed on respective terminals, the donator data, the charitable organization data, the logistics party data, the warehouse party data and the donator data are reported to common nodes (assumed to correspond to the monitoring organization 1) of the target alliance chain, and the common nodes corresponding to the monitoring organization 1 (such as a civil hall in a certain province) perform signature verification and cross verification on the donator data, the charitable organization data, the logistics party data, the warehouse party data and the donator data.

After the signature verification and the cross verification of the above donor data, charitable organization data, logistics party data, warehousing party data and donated party data are successful, the consensus nodes of the target alliance chain can be sorted according to the time stamps of the donor data, the charitable organization data, the logistics party data, the warehousing party data and the donated party data, and then packaged into blocks to be stored in the target public welfare chain shared account book.

Similarly, suppose that the monitoring authority 2 and the monitoring authority 3 … correspond to the civil administration halls of different provinces respectively, construct a federation chain corresponding to the province, the federation chain corresponding to the province includes public benefit participant nodes corresponding to the federation chain, and link donor data, charitable organization data, logistics party data, warehouse party data and donated party data corresponding to the province to the public benefit chain shared account book corresponding to the province, so as to implement cross-domain interconnection between nodes in the federation chains of the provinces, and implement data sharing and data supervision and supervision in the federation chains.

The union chains corresponding to each province can collect the public service chain shared accounts to the public service union chain common nodes corresponding to the national core regulatory agencies through the common nodes, and therefore unified supervision of national material donation data is achieved.

In the embodiment of fig. 5, each province may further include a plurality of monitoring entities, for example, the civil administration of the city, county, or district below each province, these civil administration and the civil hall of the province may be used as the monitoring nodes of the province, and the civil hall of the province may be selected as the core monitoring node of the monitoring nodes of the province, i.e., the consensus node of the province, to perform consensus on the material donation data of the province. The consensus nodes of each province are used for uploading data with the consensus nodes of the national level, and therefore, the consensus nodes can also be called public service chain data nodes.

In the embodiment of fig. 5, a cluster composed of a plurality of distributed block link nodes may be inside the consensus node of each province and the consensus node of the entire public service alliance chain, which may adopt a Kafka consensus mechanism supported by Fabric under hyper ledger (hyper ledger), sort the consensus nodes according to timestamps of data, package the consensus nodes into blocks, and synchronize the blocks to the nodes of the corresponding alliance chain, so as to store the data in a manner that the public service chain shares the ledger, which may specifically refer to a network node communication mechanism of Fabric.

Where Kafka is a message queue through which producers can deliver messages to consumers, Kafka guarantees ordering of messages and not loss. Kafka is a distributed system, but it is itself centrally managed and relies on Zookeeper (a distributed, open source distributed application coordination service).

In the embodiment of the disclosure, cross-domain interconnection and interworking may be achieved by deploying each node in a target federation chain in different regions, and when Fabric uses Kafka, Security and authentication of data transmitted during cross-domain interconnection and interworking may be ensured by configuring TLS (Transport Layer Security) encryption and authentication.

The public welfare alliance chain visualization operation management platform on the right side of fig. 5 is a visualization for business applications, and may include a blockchain service platform, an identity authentication platform, an integrated management platform, a business audit platform, and a trusted computing platform. The block chain service platform management chain, the identity of a participant on the identity authentication platform management chain, the integrated management platform is used for butting a local reporting system and a block chain system, the service auditing platform is used for service analysis and auditing of reported data and is visual, and the trusted computing platform is another system for protecting the privacy data matched with the block chain in consideration of privacy data exchange in the future.

The target public welfare chain shared ledger in fig. 5 can be generated by each node of the target federation chain as shown in fig. 6 after the material confirmation flow is uplink, which may include information of each party concerned in the public welfare federation chain, such as registration, right confirmation, logout, release, and the like of the material, as shown in fig. 6 in detail.

In a specific implementation aspect, the donor and the recipient, whether individual or organization, may make donation reports of donated materials and donation confirmations of donated materials through charitable organizations, and the organization on the chain may include: charitable organizations, partner logistics parties, partner warehousing parties and corresponding regulatory agencies, which together build a target federation chain network as shown in fig. 4 and 5. Each public interest participant applies for a digital certificate from the authority CA to identify the identity of each public interest participant. Each public interest participant signs the information of the chain by using the private key information corresponding to the identity of the public interest participant, and the related donated material information can be chain only on the premise that the signature information is correct. The specific process of reporting the material donation data is shown in fig. 6.

In fig. 6, registration/check-out is performed first, which may include signature registration of donation declaration of donated materials by the donator, transportation and check of received donated materials by the charitable organization, the cooperative logistics party and the cooperative warehousing party, and if the test of the charitable organization and the cooperative warehousing party is correct, material registration may be initiated to the consensus node corresponding to the monitoring organization.

Specifically, the donor fills in donor data through a client installed on the terminal of the donor, signs the donor data by using a private key corresponding to the donor certificate, generates a donor signature, and sends the signed donor data to a consensus node of a target alliance chain, so that the donor data is reported. Then, the donor sends the corresponding donated materials to a charitable organization; after the charitable organization receives the donated materials, corresponding cooperative logistics parties and cooperative warehousing parties are determined, then the related information of the donated materials, the information of the determined cooperative logistics parties and cooperative warehousing parties and the information of the charitable organization are signed by a private key corresponding to a charitable organization certificate to generate a charitable organization signature, and the signed charitable organization data is sent to a consensus node of a target alliance chain through a corresponding client side of the charitable organization data to realize the report of the charitable organization data; after receiving donated materials from charitable organizations, the cooperative logistics party signs the information related to the donated materials, the determined information of the cooperative storage party and the information of the logistics party by using a private key corresponding to a logistics party certificate to generate a logistics party signature, and sends the signed logistics party data to a consensus node of a target alliance chain through a corresponding client side of the logistics party signature to realize the report of the logistics party data; after receiving the donated materials from the cooperative logistics party, the cooperative warehousing party signs the information of the transportation party transporting the donated materials, the information of the warehousing party and the like by using a private key corresponding to the warehousing party certificate to generate a warehousing party signature, and sends the signed warehousing party data to the consensus node of the target alliance chain through the corresponding client side of the warehousing party signature to realize the report of the warehousing party data.

When the common identification node of the target alliance chain receives the data reported by each node, signature verification is carried out on the common identification node, and if the signature verification of one reported data fails, the uplink fails; if the signatures pass the verification, the consensus node of the target alliance chain performs cross verification on the data uploaded by each party to see whether the data are consistent, and if the data are inconsistent, for example, if the number of donated materials reported by the cooperative warehousing party and the charitable organization are inconsistent, the chaining fails.

For example, during the process of donating materials and transporting and storing the donated materials to the cooperative warehousing department of the charitable organization, the donator, the cooperative warehousing department, and the cooperative logistics department will register and chain the donated material information, as shown in fig. 7, each KEY is the ID of each organization, the Value includes the material ID and the corresponding information including the amount of donated materials and the timestamp, and the digital signature certificate of each organization and the signature of the private KEY corresponding to the certificate on the Value, if the target public welfare chain shares the block of the same material ID already in the account (for the sake of uniqueness) or does not reach the consensus in the above cross-validation process, the chain fails. At the same time, it will check if the signature is correct, and if the signature is wrong, the uplink will fail.

If the signature verification and the cross verification are passed, the supervision authority of the target alliance chain initiates registration right-confirming operation on material declaration information, transportation material lists, warehousing check information and the like so as to generate block chain material certificates (namely the material certificates) at the common identification nodes of the target alliance chain.

The supervising authority will register the registered donated materials as block chain material voucher, as shown in fig. 7, KEY is the ID of the supervised materials, and Value contains the information of the type, name and quantity of the materials, including the information of the confirmed donator/donator and the information of which charitable organization, the cooperative logistics party and the cooperative warehousing party carry and store the donated materials, and the materials voucher is linked up after registration. If the asset ID is found to already exist, the uplink fails (here, the uniqueness of the asset ID on the chain is guaranteed).

And all the participant nodes of the target alliance chain can inquire related information according to the goods ID, and the information is transparent and sharable. At this time, the charitable organization or the government organization performs the material allocation, and the supervision organization allocates the donated materials received according to each party under the supervision material ID, records the material allocation data again for uplink, and performs the offline material distribution/transportation operation.

When the donated material is received by the donated party, there is an operation of registering confirmation of acceptance and recording the uplink. Meanwhile, the charitable organization, the cooperative warehousing party and the cooperative logistics party initiate the action of canceling the material voucher, and the supervision mechanism initiates the action of canceling the right confirmation so as to complete the closed loop on the chain of material donation.

After all parties cross-verify that the supervised material ID is issued for transportation, the supervision authority logs off the material certificate and signs with a private key corresponding to the supervision authority certificate to confirm the consensus result of all parties. If the inquired material ID information is inconsistent under the ID information of each public welfare participant corresponding to the supervised material ID, the cross validation fails, the result content is reported to the supervision authority and is synchronized to each public welfare participant, and evidence can be provided for further investigation.

According to the method for processing the material donation data based on the block chain, provided by the embodiment of the disclosure, the block chain network ecology of large-scale multi-chain multi-organization cooperation is realized through a block chain cross-domain interconnection technology. On one hand, the material donation data is linked up through a block chain technology, the data is reported to a main reporting party (including a donator, a charitable organization, a cooperative logistics party, a cooperative warehousing party and a donator) of each link to confirm the data right, and the reporting process can be traced; and a safe and credible data base is established for the whole material donation field by using a data encryption algorithm of the block chain distributed account book. Meanwhile, through the consensus processing process of block chain data storage, mutual trust of authenticity and effectiveness of all nodes added into the chain on the data is technically guaranteed, and the data on the chain has public trust on all public interest participants. On the other hand, by utilizing the sharing characteristic of the block chain distributed account book, timely and credible sharing of data among all institutions in the alliance chain is achieved, the data transparency is improved, furthermore, all public welfare participants can use the data to conduct statistics and analysis in an authorized range, for example, a monitoring institution can be in butt joint with a local data statistics and analysis system through the reported data, and the results of the statistics and analysis are displayed. In addition, the monitoring mechanism can also realize penetrating monitoring on the material donation data, and is favorable for realizing data interconnection and sharing of large-scale cooperation among organizations.
