Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art.

Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the application. One skilled in the relevant art will recognize, however, that the subject matter of the present application can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and so forth. In other instances, well-known methods, devices, implementations, or operations have not been shown or described in detail to avoid obscuring aspects of the application.

The block diagrams shown in the figures are functional entities only and do not necessarily correspond to physically separate entities. I.e. these functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.

The flow charts shown in the drawings are merely illustrative and do not necessarily include all of the contents and operations/steps, nor do they necessarily have to be performed in the order described. For example, some operations/steps may be decomposed, and some operations/steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.

The network transaction of the user is generally carried out through a network transaction platform, and if a seller who is resident on the platform needs to collect money, the seller needs to go to a third-party payment mechanism through the platform to register and apply for qualification of collecting the money. When a real transaction occurs, a buyer on the platform pays funds to a seller through a payment service provided by a third-party payment mechanism, the platform is used as a transaction scene provider and needs to obtain certain fees from the transaction, at the moment, the platform needs to call a billing interface of the third-party payment mechanism, partial funds in the transaction are transferred to a profit account opened by the platform at the third-party payment mechanism according to the agreement between the platform and the seller, and the rest funds can be transferred to an available balance account of the seller. In the process, the platform has certain control right on the funds received by the seller, and the seller needs to wait for the completion of platform call accounting when the seller wants to receive the actual available funds. In the process, the third-party payment mechanism completely trusts the billing instruction of the platform, and if the platform is in error or malicious billing instruction is generated, the seller receives funds which are not calculated according to the convention between the seller and the platform, and the third-party payment mechanism is difficult to confirm and intercept the abnormal behaviors. Therefore, the problems of poor fund distribution accuracy, poor credibility and the like in network transaction are caused.

In order to solve the situation of abnormal accounting command information in the accounting flow, an embodiment of the present application provides an accounting contract generation scheme based on a block chain and multiple signatures, where an accounting contract refers to a related contract between a third-party payment mechanism and a capital accounting signed by a resident merchant and a platform, and indicates a series of accounting-related matters such as accounting timing, maximum amount, maximum proportion, and the like, and the third-party payment mechanism completes an accounting task according to the contract in combination with a specific accounting command of the platform.

According to the technical scheme provided by the embodiment of the application, the third-party payment mechanism is brought in when the platform and the seller contract the ledger, so that the third-party payment mechanism can verify that the ledger instruction of the platform meets the ledger contract, and the contract establishment of the ledger contract is confirmed by the signatures of the platform and the seller. Meanwhile, the process data and the result data bound by the account separation contract are stored through the block chain, and the data effectiveness of the account separation contract can be better ensured by utilizing the characteristics of safe storage of the block chain and incapability of tampering the data.

The technical scheme provided by the embodiment of the application relates to transaction service scenes such as network payment and account transfer realized based on a BlockChain (Blockchain) technology. The blockchain is an anti-counterfeiting, anti-tampering and traceable shared digital account book with a blockchain data structure, which is constructed by transparent and credible rules under a peer-to-peer network environment. The block chain type data structure is a data structure which stores transactions occurring in a period of time in units of blocks and connects the blocks into a chain in time sequence by a cryptographic algorithm. Accounts are distributed to all member nodes in the network, and a history of asset transactions occurring between peer nodes in the network is permanently recorded in a sequential chain of blocks linked by a hash cipher algorithm. All validated and certified transactions are linked from the beginning of the chain all the way to the latest tile, hence the named tile chain. Blockchains can act as a single source of facts, and members in a blockchain network can only view the transactions that are related to them.

Fig. 1 shows a schematic block chain system in the embodiment of the present application, where the block chain system 100 may include at least one client 110 and a block chain network 120, and the block chain network 120 includes at least one block chain node 121. The client 110 may be a smart phone, a tablet computer, a notebook computer, a desktop computer, an intelligent wearable device, an intelligent vehicle-mounted device, an intelligent payment terminal, a facial recognition terminal, or other various electronic devices, and may provide a block chain data service to a user by installing a corresponding client application program. The blockchain node 121 may be a terminal device or a server, for example, the blockchain node 121 may be an independent physical server, may also be a server cluster formed by a plurality of physical servers, and may also be a cloud server providing cloud computing services.

In the blockchain network 120, each blockchain node 121 may receive input information while performing normal operations and maintain shared data within the blockchain network based on the received input information. In order to ensure information interworking, there may be information connection between the block link nodes 121, and the block link nodes 121 may perform information transmission through the information connection. For example, when any blockchain node 121 in the blockchain network 120 receives input information and broadcasts the input information in the blockchain network 120, other node devices in the blockchain network 120 may acquire the input information according to a consensus algorithm and store the input information as shared data.

Each blockchain node 121 in the blockchain network 120 has a node identifier corresponding thereto, and each blockchain node 121 in the blockchain network 120 can store the node identifiers of other blockchain nodes in the same blockchain network, so that the generated block is broadcast to other nodes in the blockchain network 120 according to the node identifiers of other blockchain nodes in the subsequent process. A node identifier list as shown in table 1 may be maintained in the blockchain node 121, and the node name and the node identifier are correspondingly stored in the node identifier list. The node identifier may be an IP (Internet Protocol) address and any other information that can be used to identify the node, and table 1 is a node identifier list taking an IP address as an example.

TABLE 1

Node name	Node identification
		Node 1	117.114.151.174
Node 2	117.116.189.145
		…	…
Node N	119.123.789.258

Fig. 2 shows the constituent structure of a blockchain maintained on a blockchain network. As shown in fig. 2, the blockchain is composed of a plurality of blocks connected in sequence, and whenever new data needs to be written into the blockchain, the data is collected into a newly generated block, and the newly generated block is linked to the end of the blockchain, and the newly added block on each node device 121 can be guaranteed to be identical through the consensus algorithm. The data of the current block is recorded in the block body of each block, and the Hash value (Hash) of the previous block connected with the current block is stored in the block head of each block, and if the transaction data in the previous block changes, the Hash value of the current block changes accordingly. Therefore, the data uploaded to the blockchain network is difficult to tamper, and the reliability of the shared data can be improved.

The following detailed description will be made on technical solutions of a resource allocation method, a resource allocation apparatus, a computer-readable medium, and an electronic device provided by the present application, with reference to specific embodiments.

Fig. 3 schematically shows a network architecture of a blockchain network to which the technical solution of the present application is applied. As shown in fig. 3, in an application scenario of implementing network transaction and network payment, a transaction subject node 310, a transaction platform node 320, and a resource allocation node 330 located in a blockchain network jointly maintain one or more blockchains 340.

The transaction subject node 310 is a block link node that provides transaction services to the user, and may be, for example, a merchant or an individual seller that conducts a network transaction with the user.

The trading platform node 320 is a block node that provides a trading scenario for network trading, and may be, for example, an e-commerce website, a network mall, or various service platforms that provide network trading services.

Resource allocation node 330 is a block-linked node that provides funds management and allocation services for network transactions, and may be, for example, a third party payment authority.

When a user performs a network transaction with the transaction subject node 310, the transaction funds may be paid to the transaction subject node 310 through an account opened on the resource allocation node 330, and the transaction platform node 320 serves as a provider of a transaction scenario, and a certain amount of funds need to be extracted from the transaction funds to serve as a platform service fee. To achieve reliable fund distribution between the trading subject node 310 and the trading platform node 320, a corresponding intelligent contract (e.g., a split account contract) for fund distribution may be established based on the blockchain network, and when a network trade is generated, the resource distribution node 330 may distribute the fund to each object in the trading scenario according to the intelligent contract.

In order to ensure the effectiveness and the credibility of contract formation, the process data and the result data of the contract formation can be uplink stored through the block chain 340, and the centralized contract formation and data storage can effectively avoid the trust crisis.

Fig. 4 schematically shows a flowchart of steps of a resource allocation method in an embodiment of the present application, where the resource allocation method may be executed by the client 110 or the block chain node 121 shown in fig. 1, and the embodiment of the present application specifically uses the resource allocation method executed by the resource allocation node 330 as an example for explanation. As shown in fig. 4, the resource allocation method may mainly include the following steps S410 to S430.

Step S410: and sending the contract template for agreeing the resource allocation rule to a trading platform node in the block chain network so that the trading platform node performs content filling and signature processing on the contract template to obtain the single-party signature intelligent contract carrying the digital signature of the trading platform node.

In the block chain network, firstly, a resource allocation node sends a contract template to a trading platform node, wherein the contract template is used for agreeing a resource allocation rule for allocating resources to the trading platform node and a trading subject node. The contract template can be a template which is pre-configured on the resource allocation node according to the agreement between the trading platform node and the resource allocation node, and when the contract establishment requirement is generated, the resource allocation node sends the contract establishment requirement to the trading platform node. In the embodiment of the present application, the same or different contract templates may be configured between each resource allocation node and each trading platform node.

In one embodiment of the application, the resource allocation node may transmit the contract template to the trading platform node according to the communication address of the trading platform node based on point-to-point data transmission. In the embodiment of the application, the resource allocation node can obtain the node address and the node public key of the trading platform node, and the contract template for agreeing the resource allocation rule can be encrypted according to the node public key of the trading platform node to obtain the encrypted contract template. And the transaction platform node decrypts the encrypted contract template by using a node private key matched with the node public key to obtain the contract template.

In one embodiment of the present application, the resource allocation node may broadcast the contract template over the blockchain network, so that the trading platform node can obtain the contract template by listening to the broadcast message.

In one embodiment of the present application, the resource allocation node may store the latest contract template on the blockchain, and when a contract establishment requirement is generated, the trading platform node may query the blockchain for the blockdata to obtain the corresponding contract template. In this embodiment of the present application, a resource allocation node may broadcast a contract template for agreeing on a resource allocation rule on a blockchain network, so as to write the contract template into a to-be-uplink blockchain of each blockchain node on the blockchain network; when the block generation condition is met, broadcasting a block to be uplink-linked, which carries a contract template, on the block chain network so that each block link point on the block chain network performs common identification authentication on the block to be uplink-linked, and performing uplink processing on the block to be uplink-linked after the authentication is passed; and sending the block height of the target block where the contract template is located to the trading platform node so that the trading platform node can inquire in the target block to obtain the contract template.

The contract template comprises pre-agreed clause data and data to be filled which needs to be perfected according to actual transaction requirements. After the trading platform node obtains the contract template, the data to be filled in the contract template can be filled with the content, and therefore the intelligent contract with complete content is obtained. The data to be populated may include, for example, transaction accounts, contact details, etc. of the various transaction parties.

After the contract template is filled with the content, the trading platform node can perform signature processing on the contract template to obtain the single-party signature intelligent contract carrying the digital signature of the trading platform node. The digital signature is a digital string which can be generated only by a sender of the information and cannot be forged by others, and the digital string is a valid proof of the authenticity of the information sent by the sender of the information. The trading platform node can ensure the source validity and the content validity of the intelligent contract by carrying out signature processing on the contract template filled with the content.

Step S420: and sending the single-party signature intelligent contract to a trading subject node in the block chain network so that the trading subject node performs content verification and signature processing on the single-party signature intelligent contract to obtain a multi-signature intelligent contract carrying the digital signature of the trading platform and the digital signature of the trading subject.

After the trading platform node carries out signature processing to generate the single-party signature intelligent contract, the single-party signature intelligent contract can be sent to the trading subject node corresponding to the single-party signature intelligent contract, so that the trading subject node can verify the contract content of the single-party signature intelligent contract, and the digital signature of the trading subject node can be further added to the single-party signature intelligent contract to obtain the multi-signature intelligent contract carrying the signatures of both parties.

In an embodiment of the application, the transaction platform node may return the unilateral signature intelligent contract obtained after completing the content filling and signature processing to the resource allocation node, and then the resource allocation node sends the unilateral signature intelligent contract to the transaction host node.

In one embodiment of the application, the trading platform node can transmit the single-party signature intelligent contract to the trading platform node according to the communication address of the trading subject node based on point-to-point data transmission.

In one embodiment of the present application, the transaction platform node may broadcast the one-party signed intelligent contract on the blockchain network, so that the transaction subject node can obtain the one-party signed intelligent contract by monitoring the broadcast message.

In one embodiment of the present application, the transaction platform node may store the unilateral signature intelligent contract on the blockchain, so that the transaction subject node may obtain the corresponding unilateral signature intelligent contract by querying the blockchain for the blockdata.

After the trading subject node obtains the single-party signed intelligent contract, the trading subject node can perform content verification on the intelligent contract to determine the content accuracy of the contract, for example, whether content data filled by the trading platform node in the contract content conforms to the contract of both parties can be verified. In addition, before checking the content of the single-party signed intelligent contract, the transaction subject node may first check the signature of the single-party signed intelligent contract to determine that the source of the single-party signed intelligent contract is valid and has not been tampered during transmission.

Step S430: and performing signature verification on the multiple signature intelligent contracts, and distributing resources to the trading platform nodes and the trading main body nodes according to the multiple signature intelligent contracts passing the verification.

After the resource allocation node obtains the multi-signature intelligent contract which is signed by the transaction platform node and the transaction main body node together, the signature verification can be carried out on the digital signature carried on the contract, and the source of the multi-signature intelligent contract is verified to be effective and is not tampered in the multi-party transmission and signature process.

In one embodiment of the application, the transaction agent node may transmit the multi-signature intelligent contract to the resource allocation node according to the communication address of the resource allocation node based on point-to-point data transmission.

In one embodiment of the application, the transaction principal node may broadcast the multi-signed intelligent contract over the blockchain network so that the resource allocation node can obtain the multi-signed intelligent contract by listening to the broadcast message.

In one embodiment of the present application, the transaction principal node may store the multi-signed smart contract on the blockchain, so that the resource allocation node may obtain the corresponding multi-signed smart contract by querying the blockchain for the blockdata.

When the resource allocation node determines that the multiple signature intelligent contract is accurate through verification, the resource can be allocated to the trading platform node and the trading subject node based on the content specified by the contract. For example, the multiple signature intelligent contract specifies that the transaction platform node and the transaction subject node perform resource allocation according to a certain proportion, so that the resource allocation node can divide the quantity of the resources to be allocated according to the specified proportion, and correspondingly transfer the divided resources to the transaction platform node and the transaction subject node. For another example, the multi-signature intelligent contract provides that the trading platform node charges a service fee according to a specified amount in each transaction, and the resource allocation node can extract a specified amount of resources from the resources to be allocated to transfer to the trading platform node and transfer the rest amount of resources to the trading subject node.

In the resource allocation method provided by the embodiment of the application, a contract template is provided through a resource allocation node, a trading platform node performs content filling and signature processing on the contract template to obtain a single-party signature intelligent contract, a trading main node performs content verification and signature processing on the single-party signature intelligent contract to obtain a multiple signature intelligent contract, and finally, after the multiple signature intelligent contract is subjected to signature verification by the resource allocation node, resource allocation is performed on the trading platform node and the trading main node by using the verified multiple signature intelligent contract. Based on the resource allocation method, the reliability and the credibility of network transaction can be improved, and the problem of trust crisis caused by depending on a single object is avoided.

In one embodiment of the present application, after the resource allocation node completes the verification of the multi-signature intelligent contract, the verification result of the contract and the process data contracted by the contract may be stored on the blockchain. Fig. 5 is a flow chart schematically illustrating the steps of ul saving contract order data according to an embodiment of the present application. As shown in fig. 5, the method for uplink saving of contract order data may include the following steps S510 to S540.

Step S510: and broadcasting the check result of the multi-signature intelligent contract on the block chain network so as to store the check result of the multi-signature intelligent contract into a contract buffer pool of the block chain nodes.

Each blockchain node in the blockchain network may each maintain a contract buffer pool for storing to-be-uplinked data related to a contract establishment procedure broadcast on the blockchain network. After the resource allocation node completes the check of the multi-signature intelligent contract, the check result can be stored in the contract buffer pool maintained by the resource allocation node, meanwhile, the check result can be broadcasted on the block chain network, and after other block chain nodes receive the broadcast message, the check result can be stored in the contract buffer pools maintained by the other block chain nodes, and the uplink is waited.

Step S520: process data associated with the process of contracting the multi-signed smart contract is looked up in a contract buffer pool.

Corresponding process data can be generated in the process of establishing the multi-signature intelligent contract, and the process data can comprise an original contract template, a single-party signature intelligent contract obtained after the filling and signature processing of the trading platform node, and a request message and a response message generated in the process of carrying out contract transmission among the resource allocation node, the trading platform node and the trading subject node. In the binding process, each block chain node stores the process data broadcast on the block chain network in a contract buffer pool, and after the check result of the multi-signature intelligent contract is stored in the contract buffer pool, the process data corresponding to the multi-signature intelligent contract can be searched in the contract buffer pool.

In one embodiment of the present application, a unique contract identifier (e.g., a contract number) may be assigned to a contract-making requirement, and all process data generated during the contract-making process will carry the contract identifier. In the contract buffer pool, the process data related to a multi-signature intelligent contract can be determined by inquiring the same contract identification.

Step S530: and writing the checking result of the multi-signature intelligent contract and the process data into the block to be uplink after the correlation processing.

Based on the query result in the contract buffer pool, the verification result of the multi-signature intelligent contract and the process data related to the verification result can be associated, and the associated data can be further written into the to-be-uplink block. After data is written into the to-be-uplink block, the data can be removed from the contract buffer pool, and the data which is not written into the to-be-uplink block is continuously stored in the contract buffer pool to wait for an appropriate uplink opportunity.

In one embodiment of the present application, a buffering duration of each process data in a contract buffering pool may be obtained; and if the buffering duration of the process data is greater than the duration threshold, writing the process data into the block to be uplink-linked. In order to avoid that the time span of contract establishment is too long due to network delay or data loss and the like, the embodiment of the application can record the buffer duration of buffer storage of each process data in the contract buffer pool, and when the buffer duration is greater than a set duration threshold, even if a verification result of a corresponding multi-signature intelligent contract is not obtained, the process data can be directly written into a block to be linked, so that the process data can be stored in the block to be linked when the block is newly generated.

Step S540: and when the block generation condition is met, broadcasting the block to be uplink on the block chain network so as to enable the block chain link points on the block chain network to perform common identification authentication on the block to be uplink, and performing uplink processing on the block to be uplink after the authentication is passed.

The block generation condition may include, for example, a time condition or a data amount condition, where the time condition is that a block is generated every set time duration, and when the generation time from the previous block reaches a set time duration, the block to be uplink is broadcasted, so as to generate a new block based on the result of the consensus authentication. The data volume condition means that a certain amount of block data is stored in each block, and when the data stored in the block to be uplink reaches a specified data volume, the data is broadcasted, so that a new block is generated based on the result of the consensus authentication.

Each method step of the resource allocation method in the embodiment of the present application is described in detail below with reference to a specific application scenario.
