Referring to fig. 1, an architecture diagram of a data management system based on a blockchain network according to an embodiment of the present invention includes a blockchain network 10, a blockchain network node 101, a target enterprise corresponding to a first terminal 11, a target vendor corresponding second terminal 12, a financial institution corresponding third terminal 13, and a downstream vendor corresponding terminal 14. Wherein:
the blockchain network 10 specifically refers to a network in which data sharing is performed from node to node, and a plurality of nodes 101 may be included in the blockchain network. Each node 101 may receive input information while operating normally and maintain shared data (i.e., blockchains) within the blockchain network based on the received input information. In order To ensure information intercommunication in the blockchain network, information connection can exist between every two nodes, point-To-point (P2P) communication can be realized between any two nodes, and particularly P2P communication can be performed through a wired communication link or a wireless communication link. For example, when any node in the blockchain network receives input information, other nodes acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all nodes in the blockchain network are consistent.
The first terminal 11 corresponds to the target enterprise, the second terminal 12 corresponds to the target provider, and the third terminal 13 corresponds to the financial institution can access the blockchain network and can communicate with nodes in the blockchain network. The first terminal 11 corresponding to the target enterprise, the second terminal 12 corresponding to the target provider, the third terminal 13 corresponding to the financial institution, and the terminal 14 corresponding to the downstream provider may specifically be a smart phone, a tablet computer, a notebook computer, a desktop computer, an in-vehicle smart terminal, etc., which is not limited in the embodiment of the present invention.
It should be noted that the number of nodes shown in the blockchain network 10 is merely illustrative, any number of nodes may be deployed according to actual needs, the target enterprise corresponds to the first terminal 11, the second terminal 12 corresponding to the target provider and the third terminal 13 corresponding to the financial institution may communicate with the same node in the blockchain network, or may respectively communicate with different nodes in the blockchain network.
Each node in the blockchain network has a node identifier corresponding to the node identifier, and each node in the blockchain network can store the node identifiers of other nodes in the blockchain network, so that the generated blocks can be broadcast to other nodes in the blockchain network according to the node identifiers of the other nodes. Each node can maintain a node identification list shown in the following table, and the node names and the node identifications are correspondingly stored in the node identification list. The node identifier may be an internet protocol (Internet Protocol, IP) address, or any other information that can be used to identify the node, and the table is described only by way of example as an IP address.
In some possible embodiments, a node of the blockchain network 10 may receive data to be managed submitted by a target enterprise through the first terminal 11, and write the data to be managed into the blockchain 10, where the data to be managed includes trade information between the target enterprise and a target provider corresponding to the target enterprise. Further, the node may generate a digital right voucher according to the data to be managed, and send the digital right voucher to the second terminal 12 corresponding to the target provider, so that the second terminal 12 updates the digital right voucher, the updated digital right voucher is used for the target provider to be posted from the terminal 14 corresponding to the corresponding at least one downstream provider, and the terminal 14 corresponding to the at least one downstream provider is posted from the financial institution. The node receives the updated digital right voucher transmitted by the third terminal 13 after the financial institution completes the financing posting to the terminal 14 corresponding to the at least one downstream provider, transfers to the first transfer record of the financial institution and the first generation payment result of the financing posting to the terminal 14 corresponding to the at least one downstream provider, and writes the first transfer record and the first generation payment result into the blockchain 10. By adopting the data management mode based on the blockchain network, the money settlement among the participants of the supply chain can be more convenient and safer, and the reliability of the data is improved.
It should be appreciated that the digital right voucher holder will give the data right voucher to the other party's business or user, and the act of withholding the digital right voucher holder's liabilities to the other party's business or user is considered to be utilizing the digital right voucher for liabilities. The act of the digital right voucher holder selling the digital right voucher to the financial institution to obtain funds is considered to be financing utilizing the digital right voucher.
Referring to fig. 2, a data management method based on a blockchain network according to an embodiment of the present invention is described from a node side, and the data management method based on a blockchain network includes the following steps:
s201: and the node of the blockchain network receives the data to be managed submitted by the target enterprise through the first terminal and writes the data to be managed into the blockchain.
Wherein the node is any one of the blockchain network nodes. The data to be managed includes trade information between the target enterprise and a target provider corresponding to the target enterprise, where the trade information includes one or more of target enterprise information, target provider information, trade amount, trade time, and terminal identification of the second terminal.
Specifically, a target business corresponding to the target provider corresponding to the second terminal and the target business corresponding to the first terminal sign a trade contract before the trade is conducted, wherein the trade contract comprises target business information, target provider information, trade amount and trade time. After the target provider provides the goods to the target enterprise, the target provider generates trade information for the trade through the second terminal and sends the trade information to the target enterprise. After the target enterprise obtains the trade information, the content of the trade information is confirmed based on the content in the trade contract, including whether the content in the trade information is correct or not. And if the content in the trade information is consistent with the content in the trade contract, the target enterprise confirms that the content of the trade information is correct, and submits the content of the trade information to the node through the first terminal equipment as data to be managed. After receiving the data to be managed, the node writes the data to be managed into the block chain.
In one embodiment, the second terminal should also carry the digital certificate of the target enterprise when sending the data to be managed to the blockchain node. Before the node writes the data to be managed into the blockchain, the node can also verify whether the digital certificate is legal, and if the digital certificate is legal, the node executes the step of writing the data to be managed into the blockchain. If the digital certificate is illegal, outputting an error message prompt to the first terminal, and refusing to execute the writing of the data to be managed into the blockchain.
The digital certificate is used for uniquely identifying an enterprise, the enterprise can be changed into a real-name authentication enterprise by submitting registered enterprise information to the blockchain network server, and the enterprise information comprises an enterprise name, an enterprise tax payer identification number, an enterprise detailed address, a contact way, an account opening row and an account number. And the blockchain network server verifies the authenticity of the enterprise information, issues a digital certificate for the enterprise after the verification is passed so that the enterprise becomes a real-name authentication enterprise, and writes the digital certificate and the enterprise information into a real-name registry. The method for verifying whether the digital certificate is legal may be to verify whether the digital certificate exists in the real name registry, and if so, the digital certificate is legal.
S202: the node generates a digital right crediting certificate according to the data to be managed, and sends the digital right crediting certificate to a second terminal corresponding to the target supplier, so that the second terminal updates the digital right crediting certificate, the updated digital right crediting certificate is used for the target supplier to be posted from at least one corresponding downstream supplier, and at least one downstream supplier to be posted from a financial institution.
Wherein the digital right voucher indicates the liability relationship of the target business to the target supplier resulting from the secondary trade, the digital right voucher may include one or more of liability amount (e.g. trade amount as described above), liability person (e.g. target business as described above) information, liability person (e.g. target supplier as described above) information, terminal identification, and, illustratively, after the supplier A1 has provided the 20 ten thousand yuan of goods to business B, business B submits this trade information to the node via the first terminal. The node generates a digital right voucher as shown in fig. 3a according to the trade information, wherein the digital right voucher comprises 20 ten thousand yuan of right person supplier A1, debt person enterprise B and debt amount.
The downstream provider refers to a provider that provides goods to a target provider, for example, the target provider A1 provides computers to the target enterprise B, and the provider A2 and the provider A3 respectively provide computer chips and computer hosts to the target provider A1, so that the provider A2 and the provider A3 are downstream providers of the target provider A1.
The updated digital right voucher includes at least one digital right sub-voucher brought by splitting the digital right voucher, as shown in fig. 3 b; alternatively, the updated digital right voucher includes the digital right voucher after adding the identity and the right proportion of the at least one downstream provider, as exemplarily shown in fig. 3 c.
In one embodiment, after the target provider completes the posting at the at least one downstream provider, the node may receive a second transfer record of the updated digital right voucher transmitted by the target provider through the second terminal for transfer to the at least one downstream provider and a second generation payment result of the target provider by the at least one downstream provider, and write the second transfer record and the second generation payment result into the blockchain.
Specifically, the target supplier updates the digital right vouchers by completing the liaison at least one downstream supplier, and transfers the updated digital right vouchers to each downstream supplier in accordance with the liability proportions liable to each downstream supplier. The target provider sends the transfer record of the present time (i.e., the second transfer record) and the payment result of the present time (i.e., the second payment result) to the node through the second terminal, and the node receives the updated digital creditor certificate transfer record and the payment result and writes the transfer record and the payment result into the blockchain.
In one embodiment, the updated digital right voucher includes at least one digital right sub-voucher derived from the digital right voucher split, for which case the blockchain network node may invalidate digital right vouchers generated from the aforementioned data to be recorded to avoid that the digital right vouchers are used for repeated liaison.
S203: the node receives the updated digital creditor certificate transmitted by the third terminal after the financial institution finishes financing posting on at least one downstream provider, transfers the updated digital creditor certificate to a first transfer record of the financial institution and a first generation payment result of the financing posting on at least one downstream provider, and writes the first transfer record and the first generation payment result into a blockchain.
Specifically, after the financial institution completes the financing posting to at least one downstream provider, that is, the financial institution pays the corresponding amount in the digital bond certificate to the downstream provider according to the updated digital bond certificate, the updated digital bond certificate is transferred from the downstream provider to the financial institution, the transfer record of the next updated digital bond certificate is recorded as a first transfer record, and the corresponding amount paid to the downstream provider by the next financial institution is recorded as a first payment result. Further, the node receives the first transfer record and the first payment result transmitted by the financial institution via the third terminal and writes the first transfer record and the first payment result into the blockchain.
In this embodiment of the present application, a node of a blockchain network receives data to be managed submitted by a target enterprise through a first terminal, and writes the data to be managed into a blockchain, where the data to be managed includes trade information between the target enterprise and a target provider corresponding to the target enterprise. Further, the node may generate a digital right voucher according to the data to be managed, and send the digital right voucher to a second terminal corresponding to the target provider, so that the second terminal updates the digital right voucher, the updated digital right voucher is used for the target provider to be posted from at least one corresponding downstream provider, and the at least one downstream provider is posted from the financial institution. The node receives the updated digital bond certificate sent by the third terminal after the financial institution completes the financing posting for the at least one downstream provider, transfers to a first transfer record of the financial institution and a first generation payment result of the financing posting for the at least one downstream provider, and writes the first transfer record and the first generation payment result into the blockchain. By adopting the data management mode based on the blockchain network, the money settlement among the participants of the supply chain can be more convenient and safer, and the reliability of the data is improved.
Referring to fig. 4, a data management method based on a blockchain network according to an embodiment of the present invention is described from a second terminal side, and the data management method based on a blockchain network includes the following steps:
s401: and the second terminal corresponding to the target provider receives the digital creditor certificate sent by the node of the blockchain network.

S402: the second terminal updates the digital right crediting certificate and uses the updated digital right crediting certificate to be posted from at least one downstream provider corresponding to the target provider.
In one embodiment, the second terminal obtains the number of at least one downstream provider corresponding to the target provider and the ratio of the right of each downstream provider to the target provider. Further, the second terminal may split the digital right voucher according to the number of the at least one downstream provider and the right proportion of each downstream provider to the target provider, to obtain at least one digital right sub-voucher. The second terminal sends corresponding digital creditor vouchers to each downstream provider, respectively, to complete the liaison from at least one downstream provider.
Illustratively, the downstream suppliers of the target supplier A1 are 2 in number. Target provider A1 provides target business B with 20 ten thousand yuan of goods and the node generates digital creditor vouchers as shown in fig. 3a to target provider A1. The supplier A2 provides the target supplier A1 with the goods of 8 ten thousand yuan, the right duty ratio of the digital right sub-certificate is 8/20=0.4, the supplier A3 provides the target supplier A1 with the goods of 12 ten thousand yuan, the right duty ratio of the digital right sub-certificate is 12/20=0.6, the digital right certificate shown in fig. 3a is split according to the right duty ratio, namely, the digital right certificate shown in fig. 3a is updated to the updated digital right certificate shown in fig. 3b, wherein 31 is the digital right sub-certificate of trade information of the downstream supplier A2 and the supplier A1, and 32 is the digital right sub-certificate of trade information of the downstream supplier A3 and the supplier A1. The second terminal may send 31 the digital creditor voucher to the supplier A2, the supplier A2 clears the payment owed by the target supplier A1, and the target supplier A1 completes the posting from the supplier A2. The second terminal may send the 32 digital creditor voucher to the supplier A3, and the supplier A3 clears the payment owed by the target supplier A1, and the target supplier A1 completes the posting from the supplier A3.
In one embodiment, the second terminal obtains the number of at least one downstream provider corresponding to the target provider and the right proportion of each downstream provider to the target provider, and further, the second terminal adds the identifier and the right proportion of each downstream provider to the digital right certificate to obtain the updated digital right certificate.
