Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The inventors of the present application have found, through long-term research: along with the development of the block chain, resources which can circulate on the block chain tend to be dispersed to the participants of each block chain more and more, so that the governing mechanism of the block chain can be used for maintaining the block chain system with less and less resources, and the development of the block chain system is not facilitated; for other participants, the acquired resources cannot generate new values, so that the enthusiasm of the participants in the transactions related to the block chain is reduced, the activity of resource circulation in the block chain system is further reduced, and the stable operation of the block chain is influenced.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a resource management system according to the present application. The resource management system 100 of the present embodiment includes a plurality of blockchain nodes 110 in a blockchain system. Blockchain nodes 110 may participate in the accounting services of the blockchain, and jointly maintain the blockchain distributed ledger.

One or more management nodes 111 may also be included in blockchain node 110. The management node 111 may manage resources of the blockchain system. The resources of the blockchain system may include software resources, data resources, goods, services, other resources with value, and the like of the blockchain, and the data resources may include digital currency or other digital currency of the blockchain. The management node 111 may perform management operations such as provisioning or receiving of resources of the blockchain system.

The resource management of the blockchain system is performed through, for example, a common resource library configured on the blockchain, and resources in the common resource library can be used for the governance of the blockchain. The management node 111 may implement resource management on the blockchain system through a common resource library.

For example, the management node 111 may receive the resources of the public node 120 and place the resources in the public resource pool. Management node 111 may also use a chain of resource governance blocks in a common resource pool. The management node 111 may be a specific node in the blockchain system, such as a founder node, some nodes selected in the blockchain system that operate stably and have a high reputation, or a node operated by an administration mechanism of the blockchain system. Multiple management nodes 111 may collectively manage the resources of the blockchain system. Alternatively, the management nodes 111 may manage different types of resources in the blockchain system.

The resource management system 100 of the present embodiment further includes a public node 120. The public nodes 120 may include nodes other than the blockchain management node 111, such as other blockchain nodes 110, blockchain light nodes, or other network nodes in a blockchain system. The definition of public node 120 in this application is to be distinguished from traditional private nodes. The public node 120 may be a block link point 110 that can openly interact with the outside before the purpose of the present application is achieved, resources can circulate in a block chain, and a block chain system is not broken down or left to stand due to resource exhaustion. The public node 120 may communicate with the management node 111, initiate a resource provisioning request to the management node 111, and provision the management node 111 with corresponding resources for use. The public node 120 may also obtain the corresponding certificate issued by the management node 111 after providing the resource to the management node 111, and may obtain a certain feedback when the resource is recovered.

The public node 120 may also be used to enable user interaction with the blockchain network. For example, the public node 120 may include a terminal device, such as a computer, a mobile phone, a tablet computer, and the like, and may receive a resource provision instruction input by a user, and send a corresponding resource provision request to the management node 111; and also receives the resource-provided credentials issued by the management node 111 and presents them to the user.

In this embodiment, after the public node 120 sends the resource providing request to the management node 111, the management node 111 may further generate a contract corresponding to the resource providing request by using an intelligent contract of the block chain, and after receiving the resource of the public node 120, execute the contract to automatically issue a credential provided by the corresponding resource to the public node 120. The management node 111 can also use the resources provided by the public node 120 for governance of the blockchain according to the provision of the contract, thereby maintaining the healthy and stable development of the blockchain. The management node 111 executes corresponding operation through the intelligent contract, so that human intervention can be reduced, and the reliability is improved.

In this embodiment, the resource management system 100 may further include a resource information platform 130. The resource information platform 130 may include a client, a website, and the like, and the resource information platform 130 may be configured to manage information related to resource demand or supply, and provide a corresponding information query service. For example, the management node 111 may publish the resource staging information through the resource information platform 130 and the public node 120 may query the resource staging information on the resource information platform 130.

The resource information platform 130 may be configured in the blockchain system, and may collect resource raising information issued by the management node 111 in the blockchain system, and provide an effective information query channel to the public node 120, so that not only the resource raising information can be quickly and effectively disclosed, but also information privacy security in the blockchain system can be effectively protected. Or, the resource information platform 130 may also be a public information platform, and may collect resource raising information of a plurality of blockchain systems, and provide corresponding information query channels or a unified information query channel, respectively, so as to be beneficial to the public node 120 to obtain more comprehensive information when participating in multiparty resource raising, and also to the benefit of each blockchain system to seek more resource providing.

The management node 111 can manage resources of the block chain system, and receive resources of the public node 120 through the public resource library, so that more resource accumulation can be obtained for the block chain system, the management node 111 can use the accumulated resources for managing the block chain, the public node 120 can also obtain corresponding feedback by providing the resources, so that the resources in the block chain system circularly flow, the block chain system cannot be collapsed due to resource exhaustion, new values can be continuously generated, and the health, stability and sustainable development of the block chain can be promoted; and the management node 111 performs resource management through the intelligent contract, so that human intervention can be reduced, and the reliability of resource management is improved.

Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a resource management method based on a block chain according to a first embodiment of the present application. The embodiment comprises the following steps:

s101: the management node receives a resource providing request of the public node.

In this embodiment, the management node may receive a resource providing request from the public node. When determining to provide the resource to the management node, the public node may initiate a corresponding resource providing request, for example, directly send the resource providing request to the management node; or, the public node may also send a resource providing request to a nearby block link point, and the resource providing request is forwarded to the management node by the block link point.

The resource provisioning request may be for requesting the management node to receive a first resource from the public node for use. The first resource may include software resources, data resources, goods, services, other resources of value, etc., while the data resources may include digital currency of the local blockchain or other digital currency, etc. The first resource may include one or more types of resources. The public node may initiate a resource provisioning request for one or more types of resources. The resource providing request includes, for example, identity information of the public node, information on the provided resource, and the like. When receiving the resource providing request, the management node can determine whether to receive the resource provided by the public node according to the corresponding resource requirement.

In this embodiment, the resource management request may further be used to define a rule for the management node to return the first resource and/or the second resource to the public node. After receiving the resources provided by the public node, the management platform can return the first resources to the public node according to the corresponding resource return rule, and can also return the second resources to the public node. The second resource may include software resources, data resources, goods, services, other valuable resources, etc., while the data resources may include digital currency of the local blockchain or other digital currency, etc. The second resource may be of the same or different resource type than the first resource. The second resource can be used as the public node to provide feedback of the first resource and is used for stimulating the public node to participate in providing the enthusiasm of the resource, so that the quick accumulation of the resource is facilitated.

The rule that the management node returns the first resource and/or the second resource to the public node includes, for example, a return time, a return address, a return mode, and the like. For example, in the resource management request, it may be defined that the time when the management node returns the first resource and the second resource to the public node respectively is within a preset time after the management node receives the first resource, the return addresses of the first resource and the second resource are resource pool addresses corresponding to the public node, and the return mode is a fractional return. The rule for the management node to return the first resource and the second resource to the public node may be the same, for example, the management node may be defined in the resource management request to return the first resource and the second resource at the same time. Optionally, the rules for the management node to return the first resource and the second resource to the public node may also be different, and the management node may return the first resource or the second resource to the public node according to the corresponding return rules, respectively.

Optionally, the resource providing request may further include a processing rule after the default. For example, the resource providing request may specify a processing rule when the management node does not return the first resource or the second resource according to the return time or the return mode.

S102: and the management node calls the intelligent contract to generate a contract corresponding to the resource providing request.

After receiving the resource providing request of the public node, the management node can call the intelligent contract of the block chain to generate a corresponding contract. In this embodiment, the management node is configured with an intelligent contract of the block chain, and the intelligent contract may be used to specify rules for receiving or supplying resources. The management node generates a contract corresponding to the resource providing request by calling an intelligent contract, and the contract can be used for standardizing the rules of receiving or supplying the resource provided by the public node.

In this embodiment, the contract may further include a rule that the management node returns the first resource and/or the second resource to the public node. For example, the management node may extract related information of a rule that the management node defined in the resource providing request returns the first resource and/or the second resource to the public node, and write the related information into the contract, so that the management node may automatically return the first resource and/or the second resource to the public node by executing the contract according to the corresponding return rule in the contract. The management node performs resource management by using the intelligent contract of the block chain, so that the credibility of the resource management can be effectively improved, and the resource security of the public node is protected.

Optionally, after receiving the resource providing request, the management node may further determine whether the resource providing request meets the corresponding resource requirement, and when determining that the corresponding resource requirement is met, invoke the intelligent contract to generate a contract corresponding to the resource providing request.

For example, the management node may determine whether the identity of the public node is legal, and generate a corresponding contract when determining that the identity of the public node is legal, so that a situation that resource raising efficiency is low due to the computing power of the management node occupied by a malicious resource providing request may be effectively reduced. The management node can also judge whether the resource type, the resource quantity, the resource providing time and the like provided by the public node meet the corresponding resource requirements, and accept the resource provision of the public node when judging that the resource requirements are met, and generate a corresponding contract. The management node judges and screens the resource providing request in advance, and therefore the management node is beneficial to rapidly and accurately raising the required resources.

S103: the public node transfers the first resource to a public resource pool.

In this embodiment, the common resource pool may be used for managing resource supply or reception of the blockchain system. After initiating the resource providing request, the public node may transfer the corresponding first resource to the public resource pool of the block chain. Alternatively, the public node may transfer the first resource to the public resource pool upon sending the resource provision request. Alternatively, the public node may transfer the first resource to the public resource pool within a preset time after sending the resource providing request. Or, the public node may further transfer the first resource to the public resource pool after receiving the message that the management node confirms to accept the resource provision.

The management node can receive the first resource transferred to the public resource library by the public node and can also use the resource in the public resource library. After receiving the first resource transferred to the public resource library by the public node, the management node can also issue a corresponding certificate to the public node. In some embodiments, the managing node receiving the public node transfer to the first resource in the common resource repository may further include: judging whether the public resource library receives a first resource of the public node within a preset time after receiving the resource providing request; if the first resource is received, the step of S104 may be executed; if the first resource is not received, a contract may be executed to end the resource provisioning of the public node.

For example, the management node may start timing after receiving the resource providing request of the public node, and determine whether the public node transfers the corresponding first resource to the public resource repository within a preset time, so as to determine the authenticity of the resource provided by the public node. Optionally, if the management node determines that the public resource pool does not receive the first resource of the public node within the preset time, the management node may execute a contract to end the resource provision. Alternatively, the contract may also specify the processing rules for the breach. And if the management node judges that the public resource library does not receive the first resource within the preset time, the management node can execute the contract to process according to the corresponding processing rule.

In some embodiments, the contract may further include resource provision rules of the public node, for example, a resource type, provision time limits respectively corresponding to different types of resources, a resource quantity, a resource provision manner, and the like. For example, the contract may specify that the type of the received resource is digital currency of the block chain, and limit the resource providing time limit to be within five days after receiving the resource providing request, the resource providing mode is one-time providing or multiple-time providing. When the resources provided by the public node include a plurality of different types of resources, the contract may further specify rules for providing the resources of each type, including but not limited to a time limit for providing, a quantity of the resources, a manner of providing the resources, and the like.

S104: the management node executes the contract to generate credentials provided by the first resource.

After receiving the first resource transferred to the public resource library by the public node, the management node can execute the contract to generate a first resource providing certificate. The credential may serve as a basis and proof for the public node to provide the first resource to the management node. The credential is generated by the management node based on the type, amount, providing time, and other relevant information of the first resource, for example, and can maintain a providing record of the first resource. The voucher may also be a digital resource similar to a bond that can be used to redeem other resources for corresponding value.

Optionally, the management node may further configure identification information provided by the first resource, where the identification information is stored in association with the provision record of the first resource. The management node may also generate a corresponding credential based on the identity of the public node and the identification information provided by the first resource. Therefore, the security of the private information of the first resource provided by the public node can be effectively protected.

The management node may also issue a credential to the public node after generating the credential provided by the first resource. For example, the contract may also specify relevant rules such as the format of the credential, the generation conditions, the issuance time, the issuance mode, and the like. After receiving the first resource transferred to the public resource library by the public node, the management node can execute the contract to judge that the voucher provided by the first resource in the corresponding format is generated when the corresponding generation condition is met, and issue the voucher provided by the first resource to the public node in the effective issuing time. The public node can confirm the validity of the first resource supply after receiving the certificate.

In this embodiment, after initiating the resource providing request, the public node may also transfer the first resource to the public resource pool for multiple times. The management node can also execute the contract to generate the resource providing voucher of the corresponding part after each time the public node transfers part of the resources to the public resource library, so that the timeliness of obtaining the corresponding voucher by each resource provided by the public node can be effectively guaranteed, and the safety of each resource provided by the public node is protected.

In some embodiments, when the management node generates the credential provided by the first resource, the management node may further configure an operation rule corresponding to the credential. For example, the management node may configure the valid redemption time of the credential, whether transferable, the manner of transfer or destruction, etc. The management node can also write the relevant operation rule of the certificate into the contract by using an intelligent contract, and the safety degree and the credibility of the certificate are improved by judging the validity of the certificate or the validity of the operation of the public node on the certificate through executing the contract. Optionally, the management node may also sign the certificate issued to the public node to identify the source of the certificate, thereby improving the credibility of the certificate.

In this embodiment, the receiving and supplying of the resources in the blockchain system, and the generation, issuance, transfer, or destruction of the credential and other related operations are all stored in the blockchain distributed ledger, so that the operation records of the resources or the credential can be actively checked, and the reliability of resource management is effectively improved.

S105: the management node uses at least a portion of the first resource for administering the blockchain.

In this embodiment, the management node may use resources in the public resource pool, for example, at least part of the first resource in the public resource pool is used for governing the block chain. For example, the management node may use at least part of the first resource for maintenance of the blockchain network, maintenance and updating of node devices in the blockchain system, or reward for participation of blockchain nodes in blockchain transactions, etc.

The management node can utilize corresponding resources to process the block chain according to the requirements of the block chain system so as to maintain the healthy and stable development of the block chain. Alternatively, the management node may also use the first resource in the common resource pool by executing an intelligent contract. For example, the management node generates a contract corresponding to the resource providing request, and the contract may also be used to specify a usage rule of the first resource. The usage rule of the first resource includes, for example, applicable object, usage time, usage amount, and other relevant specifications for the first resource. When the first resource includes multiple types of resources, the contract may further include usage rules corresponding to each type of resource. The usage rule of the first resource may be formulated by the management node according to the requirement of the blockchain system, and written into the contract after being confirmed by the public node. The management node pays out the first resource by executing the contract, so that the fairness and the reliability of resource asset paying out can be ensured, and the possibility that the first resource is maliciously used is reduced.

Optionally, the using, by the management node, at least part of the first resource for governing the blockchain may further comprise: the management node judges whether the use of the first resource meets the use rule; if the usage rules are met, executing a contract to draw at least part of the first resource from the public resource library for use in governing the blockchain; if the usage rule is not satisfied, the operation of drawing at least part of the first resource from the public resource library is not executed.

The usage rule of the first resource may include one or more rules such as an applicable object, a usage time, a usage amount, and the like, and the management node may determine the validity of the resource usage by performing a judgment on a corresponding item when the first resource is fetched. For example, in one particular embodiment, the first resource is an amount of digital currency, and the contract specifies that half of the first resource is to be used for blockchain network maintenance; when the management node fetches the first resource from the public resource library, it may determine in advance whether the usage of the first resource is correct, and whether the number of the fetched first resource exceeds the number specified by the contract; if the management node judges that the resource use is correct and no excess support exists, a first resource can be taken from the public resource library for use; if one of the items is determined to be not eligible, such as being used incorrectly or being out of order, then the expenditure of the first resource may be abandoned. The management platform can prevent the first resource from being used disorderly by judging whether the use of the first resource meets the use rule specified by the contract or not, and the safety of the resource in the public resource library is improved.

The management node of the embodiment can receive the first resource of the public node through the public resource library, so that more resource accumulation can be obtained for the block chain system; at least part of the first resources are used for managing the block chain by the management node, and the public node can also obtain corresponding second resources as feedback by providing the first resources, so that the resources in the block chain system flow circularly, the block chain system cannot be broken down due to resource exhaustion, new values can be generated continuously, and the health, stability and sustainable development of the block chain can be promoted; and the management node performs resource management through the intelligent contract, so that the human intervention can be reduced, and the reliability of the resource management is improved.

In this embodiment, the sequence of steps S101 to S105 is the description sequence in this embodiment, and is not limited to the sequence of the resource management method based on the block chain in the execution process in this embodiment, and on the premise that the method can be implemented, some steps may be executed simultaneously or individually by exchanging the sequence.

Referring to fig. 3, fig. 3 is a flowchart illustrating a resource management method based on a block chain according to a second embodiment of the present invention. This embodiment is further described on the basis of the first embodiment of the resource management method based on a block chain in the present application, and the same steps as those in the first embodiment of the resource management method based on a block chain in this embodiment are not described herein again. The embodiment comprises the following steps:

s201: and the management node issues the resource raising information on the resource information platform.

In this embodiment, the resource management system further includes a resource information platform. The resource information platform may be used to collect and display resource raising information. The management node may also issue the resource staging information through a resource information platform before receiving a resource providing request of the public node. The management node issues the resource raising information, so that the corresponding resource requirements of other public nodes can be informed, the management node can seek more resources, and the resource raising efficiency is improved.

The resource raising information includes, for example, the resource type, the resource amount, the resource receiving address, the resource raising time, the resource return rule, the credential issuance rule, and other relevant information of the resource to be raised by the management node. When the resource raising types are various, the resource raising information may further include related information such as the number of each type of resource, the receiving address, and the like. The resource raising time is, for example, a time during which the management node receives the resource provided by the public node and is effective, and the management node can receive the resource of the public node during the raising time. The resource return rule includes, for example, the type, time, and other resource related rules for returning the resource after the management node receives the resource provision. The certificate issuing rules include, for example, relevant regulations such as issuing time, issuing mode, operability, and the like.

Optionally, the management node may also send the resource raising message to a block link point in the block chain network, and the block link point may also serve as a public node to provide resources to the management node to assist the management node in performing resource raising.

S202: and the public node inquires the resource raising information through the resource information platform.

In this embodiment, the resource information platform may further provide an information query channel, and after the management node issues the resource raising information on the resource information platform, the public node may query the resource raising information through the query channel of the resource information platform. The public node can obtain relevant information such as corresponding resource types, resource quantity, resource receiving addresses, resource raising time, resource returning rules, credential issuing rules and the like by inquiring the resource raising information.

In some embodiments, the resource information platform may also be a common information platform that may receive resource staging information sent by management nodes of multiple blockchain systems. The resource information platform can also be configured with the corresponding serial number of the resource raising information, so that the resource raising information of multiple parties can be managed in order. The public node may query the resource information platform for a plurality of resource staging information and determine to provide the corresponding resource to one or more of the resource staging projects by screening matches.

S203: and the public node sends a resource providing request about the resource corresponding to the resource raising information to the management node.

In this embodiment, after querying the resource raising information on the resource information platform, the public node may send a corresponding resource providing request to the management node when determining to provide the resource to the management node. Optionally, the resource providing request may further include a serial number of the resource raising information, so that the management node may further confirm the corresponding resource raising item after receiving the resource providing request.

In some embodiments, after the public node queries the resource raising information, the public node may further send a resource providing request to the management node through the resource information platform. For example, when determining that a resource is provided for a resource aggregation project corresponding to a certain number, the public node sends the number and related information of the resource to be provided, such as a resource type, a resource quantity, and the like, to the resource information platform, and after receiving the information, the resource information platform may generate a resource providing request of the public node based on the corresponding information and send the resource providing request to the corresponding management node.

S204: the management node obtains a first parameter in the resource raising information and a second parameter in the resource providing request.

After receiving the resource providing request of the public node, the management node can also extract a first parameter in the resource raising information and a second parameter in the resource providing request. The first parameter in the resource raising information includes, for example, a resource type, a resource amount, a resource receiving address, a resource raising time, a resource return rule, a credential issuance rule, and other relevant parameters of the resource to be raised by the management node. The second parameter in the resource providing request includes, for example, the resource type of the resource to be provided by the public node, the resource quantity, the time for providing the resource, the resource return address, and other relevant parameters.

In this embodiment, when the management node issues the resource raising information on the resource information platform, the first parameter in the resource raising information may also be saved. When receiving a resource providing request of a public node, the management node can directly call the stored first parameter, so that operation steps can be effectively saved, and the calculation efficiency is improved. When the management node issues the resource raising information on the resource information platform, the resource raising information can be broadcasted to the block chain network for distributed storage, so that the credibility of the resource raising is effectively improved. S205: the management node invokes an intelligent contract to generate a contract based on the first parameter and the second parameter.

After the management node obtains a first parameter in the resource raising information and a second parameter in the resource providing request, an intelligent contract of the block chain can be called, the first parameter and the second parameter are written into the intelligent contract to generate a contract based on the first parameter and the second parameter, and the contract is subjected to distributed storage after consensus confirmation.

Optionally, after generating the contract based on the first parameter and the second parameter, the management node may further feed back a message confirming acceptance of resource provision of the public node to the public node. Or, the management node may also feed back a message of receiving the resource provision of the public node to the resource information platform, and the resource information platform may further feed back to the public node and prompt the public node to provide a corresponding resource to the management node.

S206: the public node transfers the first resource to a public resource pool.

In this embodiment, the public node may transfer the corresponding first resource to the public resource pool within an appointed time after determining that the management node confirms to receive the resource provision. When the first resource comprises multiple types of resources, the public node can transfer the multiple types of first resources to the public resource library simultaneously or sequentially.

S207: the management node executes the contract to generate credentials provided by the first resource.

In this embodiment, the management node may receive a first resource transferred from the public node to the public resource library of the block chain, and execute a contract to generate a corresponding credential after receiving the first resource. The management node may also issue the corresponding credentials to the public node so that the public node may confirm the validity of the first resource provision upon receiving the credentials.

S208: the management node uses at least a portion of the first resource for administering the blockchain.

In this embodiment, the management node may obtain the first resource from the public resource library, and may further use at least a part of the first resource for managing the resource information platform, so as to effectively maintain stable operation of the resource information platform and protect security and validity of relevant information in the resource information platform.

In the embodiment, the management node issues the resource raising information through the resource information platform, so that the resource raising information can be quickly and effectively disclosed, more resource supplies can be searched through the resource information platform, and the resource raising efficiency is improved; at least part of the first resources are used for managing the block chain by the management node, and the public node can also obtain corresponding second resources as feedback by providing the first resources, so that the resources in the block chain system flow circularly, the block chain system cannot be broken down due to resource exhaustion, new values can be generated continuously, and the health, stability and sustainable development of the block chain can be promoted; and the management node performs resource management through the intelligent contract, so that the human intervention can be reduced, and the reliability of the resource management is improved.

In this embodiment, the sequence of steps S201 to S208 is the description sequence in this embodiment, and is not limited to the sequence of the resource management method based on the block chain in the execution process in this embodiment, and on the premise that the method can be implemented, some steps may be executed simultaneously or individually by exchanging the sequence.

Referring to fig. 4, fig. 4 is a schematic flowchart illustrating a resource management method based on a block chain according to a third embodiment of the present application. This embodiment is further described on the basis of the first embodiment of the resource management method based on a block chain in the present application, and the same steps as those in the third embodiment of the resource management method based on a block chain in this embodiment are not described herein again. The embodiment comprises the following steps:

s301: the management node receives a resource providing request of the public node.

S302: and the management node calls the intelligent contract to generate a contract corresponding to the resource providing request.

S303: the public node transfers the first resource to a public resource pool.

In this embodiment, the blockchain system may include a plurality of common resource pools, and each common resource pool is respectively used for managing supply or reception of different types of resources. The public node provides the first resource to the management node, and the first resource is stored in the corresponding public resource library, so that the management node is favorable for orderly managing multiple types of resources in the blockchain system.

The management node receiving the first resource transferred by the public node to the public resource library may further include storing the first resource in the public resource library of the corresponding resource type. For example, when receiving a resource providing request from a public node, the management node may provide the public node with an address of a public resource pool of a corresponding resource type, so that the public node may directly transfer the first resource to the public resource pool of the corresponding type. Or, the block chain system may be provided with an intermediate resource library, and after the public node transfers the first resource to the intermediate resource library, the management node transfers the first resource to the public resource library of the corresponding type. The arrangement of the middle resource library is beneficial to improving the resource receiving efficiency when the management node collects various types of resources, and is convenient for the classified statistics of the collected resources.

S304: the management node executes the contract to generate credentials provided by the first resource.

S305: the management node obtains a signature of a usage operation for a first resource in a common resource pool.

In this embodiment, each public repository may further be configured with a plurality of corresponding keys. The key may be used to sign usage operations of resources in a public repository to prove authenticity and validity of the usage operations. The plurality of keys configured in the public resource base can be respectively kept by the plurality of management nodes, so that the safety is improved.

Each public resource pool can be managed by a plurality of management nodes, and a plurality of configured keys can be respectively stored by the plurality of management nodes. Each management node of the blockchain system can also participate in the management of a plurality of public resource pools, and stores a key corresponding to the plurality of public resource pools. The management node may sign the usage operation of the resource in each public repository with the corresponding key, respectively.

When the management node uses at least part of the first resource for managing the block chain, the management node can utilize the corresponding key to sign the use operation of the first resource in the public resource library, and the user of the resource can be determined through the signature, so that the use of the resource can be checked. The management node can also obtain signatures of other management nodes corresponding to the public resource library on the use operation of the resources by using corresponding keys, so that the use safety of the resources in the public resource library can be effectively improved, and the possibility of malicious use of the resources can be reduced.

Optionally, the usage of the first resource in the public resource pool may also be provided with a corresponding signature rule. For example, use of a first resource in a public repository requires signing of a corresponding part or all of a key in the public repository. For example, the public repository i is configured with three keys, and the use of the first resource requires signatures of at least two keys, and then the signatures of two keys need to be satisfied when the first resource in the public repository ii is used.

In some embodiments, the usage of resources in the common repository may also configure corresponding signature rules depending on the number of resources that are paid out. For example, when the amount of resources used by the management node is large, more keys are needed to sign the use operation. For example, when the management node uses the first resource in the public resource library I, if the amount of the first resource which is paid out is large, the management node can utilize all keys to sign; if the amount of the paid first resource is small, only two keys are needed to be used for signing, and the corresponding part of the first resource can be used.

Signature rules for usage operations of resources in a common repository may also be specified by intelligent contracts for blockchains. When the management node uses the resources in the public resource library, the management node can sign the use operation by using the key by executing the corresponding intelligent contract, and when judging that the signature rule specified by the intelligent contract is met, the management node uses the corresponding resources in the public resource library. The management node automatically carries out key signature through the intelligent contract and judges whether the signature meets the signature rule, so that the human intervention can be reduced, and the safety of resource use in the public resource library is improved.

S306: the management node uses at least part of the chain of abatement blocks of the first resource.

In this embodiment, after obtaining signatures of the first resource usage operations in the public resource pool by the plurality of management nodes using the corresponding plurality of keys, the management node may execute the first resource usage operations, and draw at least part of the first resource from the public resource pool to be used for managing the block chain.

S307: the public node sends a resource recovery request to the management node.

In this embodiment, the public node may further send a resource retraction request to the management node to request retraction of at least a part of the first resource. The resource recovery request may include identity information of the public node, resource type, resource quantity, resource recovery address, and other related information. Alternatively, the resource retraction request may include information about a credential corresponding to the resource. The public node may reclaim part or all of the provided first resource from the management node by sending a resource reclaim request to the management node.

The public node may specifically send a corresponding resource retraction request to the management node according to a rule that the management node defined in the resource providing request returns the first resource and/or the second resource to the public node. For example, the time when the management node returns the first resource and the second resource to the public node may be defined in the resource management request as the resource library address corresponding to the public node, where the return addresses of the first resource and the second resource are in a preset time after the management node receives the first resource. Then, the public node may send a resource retraction request to the management node within a preset time to request to retract part or all of the first resource and a corresponding part or all of the second resource.

S308: the management node performs a contract transfer of at least part of the first resource and at least part of the second resource to the public node and reclaims or destroys at least part of the credentials.

The management node may transfer the corresponding first resource and second resource to the public node when receiving the resource reclamation request of the public node. The management node may transfer the corresponding first resource and second resource to the public node according to the resource type, the resource quantity, the resource recovery address, and the like in the resource recovery request. Or, the management node may also transfer the corresponding first resource and second resource to the public node according to the relevant information in the resource provision record of the public node stored in the block chain distributed ledger.

The management node may transfer the first resource and the second resource to the public node by transferring the respective resources from a common resource pool to the public node. Or, the management node may also transfer the corresponding resource from its own resource pool or another resource pool of the block chain to the public node, which is beneficial to improving the flexibility of resource transfer.

In this embodiment, when receiving the resource retraction request, the management node determines that the resource retraction request is correct, and satisfies a trigger rule of a contract, and may execute the contract to transfer the corresponding first resource and second resource to the public node. For example, the management node receives a resource retraction request of the public node, where the resource retraction request includes the resource quantity, the identity information of the public node and the related information of the credential corresponding to the resource, and the management node may query the issuance record of the credential in the block chain distributed ledger, determine a contract corresponding to a first resource that the public node needs to retract, and execute the contract to transfer the corresponding first resource and second resource to the public node.

When the management node transfers at least part of the first resource and at least part of the second resource to the public node, the voucher corresponding to the first resource transferred to the public node can be recovered or destroyed. When the management node returns the first resource to the public node, the corresponding voucher is withdrawn or destroyed, so that the peer between the voucher held by the public node and the remaining resource to be returned can be ensured. For example, if the resource reclamation request requires to reclaim half of the first resource, the management node may transfer half of the first resource from the public resource repository to the public node, and reclaim or destroy the credential corresponding to the part of the resource. The management node can automatically withdraw or destroy the certificate of the public node by executing a contract, so that resource loss of both parties caused by omission, mistaken withdrawal or destruction and the like can be effectively reduced.

In some embodiments, the management node may also return at least part of the first resource and at least part of the second resource to the public node and reclaim or destroy at least part of the credentials according to preset return rules specified in the contract. The preset return rules include, for example, resource return time, return address, return mode, credential processing mode, and other relevant rules. The management node may execute the contract to return a part or all of the first resource and the second resource to the public node at a preset resource return time. The management node automatically executes the operation of returning the resource through the contract, so that the operation steps of returning the resource can be effectively saved, and the safety and the reliability of returning the resource can be improved.

The method is beneficial to orderly managing the raised various types of resources by the management node by setting the plurality of public resource libraries; when the management node uses the resources in the public resource library, the management node also signs the use operation of the resources by using the key corresponding to the public resource library, so that the safety of the resources in the public resource library can be effectively improved; the management node can also return a second resource to the public node to serve as the public node to provide feedback of the first resource, so that the enthusiasm of the public node for providing the first resource is improved, more resources are raised by the management node to be used for treating the block chain, and the health, stability and sustainable development of the block chain are maintained.

In this embodiment, the sequence of steps S301 to S308 is the description sequence in this embodiment, and is not limited to the sequence of the resource management method based on the block chain in the execution process in this embodiment, and on the premise that the method can be implemented, some steps may be executed simultaneously or individually by exchanging the sequence. This embodiment may be combined with the second embodiment of the resource management method based on a block chain in the present application.
