Therefore, it is necessary to provide a general and highly scalable solution that can realize the location, acquisition, management and maintenance of resource data in the blockchain network. In the technical solution of the present disclosure, on the basis of the blockchain network, a resource analysis system and a resource storage network are set up. The resource storage network is a decentralized storage network, preferably implemented with blockchain technology, and is mainly used to store and maintain the associated information of various resource data in the blockchain network. The resource analysis system is used to provide the service of resource information analysis and query between the blockchain network and the resource storage network. The specific technical solutions are described in detail below.

FIG. 1 is a schematic diagram of a method for processing resources of a blockchain according to an embodiment of the present disclosure. The embodiment of the present disclosure is applicable to the situation of mutual positioning and acquisition of resource data between multiple chains. The method can be executed by a resource processing device of a blockchain, and the device can be implemented by means of hardware and/or software, and can be configured in an electronic device, and the electronic device can be a resource analysis system. Referring to Figure 1, the method is applied to a resource parsing system, and the method specifically includes the following:

S110. Obtain a chain resource processing request.

The chain resource processing request may be a request for processing information such as cross-chain acquisition of data resources, query of domain names, or query authority. The chain resource processing request can be directly initiated by any cross-chain resource user. For example, the initiator of the chain resource processing request can be a blockchain node.

In an optional embodiment, acquiring a chain resource processing request includes: acquiring a chain resource processing request initiated by a blockchain node; wherein the chain resource processing request is generated based on a transaction request initiated by a blockchain client.

Exemplarily, the cross-chain resource user can initiate transaction requests such as cross-chain resource acquisition or resource processing through the blockchain client according to actual needs, and send the transaction request to the resource resolution system as a chain resource processing request. The access address of the resource resolution system can be configured in the blockchain node, so that the chain resource processing request can be directly initiated to the resource resolution system.

In this optional embodiment, by obtaining the transaction request initiated by the blockchain client, the method of obtaining the chain resource processing request realizes that the cross-chain resource user on the blockchain directly initiates the chain resource acquisition and other related requests, and improves the It improves the convenience of users of cross-chain resources on the chain.

S120. According to the chain resource processing request, based on the information of the resource data stored in the resource storage network, perform resource information query to determine the resource information.

The resource storage network may be a decentralized storage network, for example, the resource storage network may be a decentralized storage network based on blockchain technology. The resource data can be the accessible resources provided in the blockchain network, and the resource information can be the associated information of the accessible resources.

Exemplarily, the resource analysis system can process the request according to the chain resource, and initiate a resource information acquisition request to the resource storage network; after the resource storage network receives the resource information acquisition request, according to the acquisition request, based on the information of the resource data stored in the network. , to query the resource information to determine the resource information corresponding to the acquisition request.

It can be understood that the resource storage network can be a blockchain network implemented based on blockchain technology. Therefore, the resource resolution system can obtain resource information by initiating a transaction request to the resource storage network. Therefore, it can not only ensure that the resource analysis system can store the information of resource data reliably and without tampering, but also ensure that operations such as query processing of resource information are reliable.

In an optional embodiment, according to the chain resource processing request, based on the information of the resource data stored in the resource storage network, performing a resource information query to determine the resource information includes: generating a resource information processing transaction request according to the chain resource processing request; The resource information processing transaction request is initiated to the resource storage network to request the resource storage network to process the resource information processing transaction request, and to feed back the resource information; wherein, the resource storage network is a blockchain network implemented based on blockchain technology.

The resource information processing transaction request may be obtained by request analysis or conversion of the chain resource processing request by the resource analysis system, and is used for the transaction request initiated to the blockchain network.

Exemplarily, if the resource storage network is a blockchain network implemented based on blockchain technology, the resource parsing system parses or converts the resource processing request after obtaining the resource processing request, and obtains the resource information processing transaction request; The parsing system initiates a resource information processing transaction request to the resource storage network. After acquiring the resource information processing transaction request, the resource storage network performs resource information query based on the information of the resource data stored in the network to determine the resource information.

In this optional embodiment, the resource analysis system may be equipped with a blockchain client of the resource storage network, so as to generate a resource information processing transaction request by processing the request according to the chain resource, and initiate a resource information processing transaction request to the resource storage network. , which realizes the initiation of transaction requests for the resource storage network based on the blockchain technology, thereby realizing the acquisition of resource information generated by the resource storage network based on the blockchain technology.

S130, responding to the chain resource processing request based on the resource information.

Exemplarily, after acquiring the resource information determined by the resource storage system, the resource resolution system may feed back the resource information to the initiator of the chain resource processing request.

In an optional embodiment, the resource analysis system may initiate a transaction request based on the blockchain client, thereby feeding back resource information to the blockchain node to which the cross-chain resource user belongs. Alternatively, the resource information can be directly fed back to the initiator of the chain resource processing request.

The solutions of the embodiments of the present disclosure determine resource information by querying the resource information based on the information of the resource data stored in the resource storage network according to the obtained chain resource processing request, and responding to the chain resource processing request based on the resource information.

Mutual positioning and acquisition of resources; multi-chain data resources are stored and maintained by a decentralized storage network, which can effectively prevent data resources from being tampered with and can be maintained and updated; the technical solution disclosed in the present invention has strong versatility and high security and reliability .

On the basis of the above technical solutions, the present disclosure also provides an optional embodiment, in this embodiment, the determination process of resource information is optimized, so as to realize the processing of chain resource processing requests according to different methods, Determine resource information. It should be noted that, for the parts that are not described in detail in the embodiments of the present disclosure, reference may be made to related expressions in other embodiments, and details are not described herein again.

Referring to a resource processing method of a blockchain shown in Figure 2, it includes:

S210. Obtain the chain resource processing request.

S220: Determine the target domain name server according to the chain resource processing request through the domain name resolver in the resource resolution system.

Among them, the domain name resolver can be used to parse the domain name and convert it into an IP (Internet Protocol, Internet Protocol) address, and the address of the domain name resolver can be pre-registered in the blockchain node for subsequent blockchain nodes. A chain resource processing request can be initiated to the domain name resolver according to the address of the pre-registered domain name resolver. Therefore, the address of at least one domain name resolver can be deployed in the blockchain node.

The domain name resolver can manage two types of information, the first type can be the request data and the status information corresponding to the request, and the second type can be the domain name server with open query authority. The request data may include the domain name, node address and resource name being queried. The status information may be the query status, for example, may include querying, querying failed, querying successful, and the like.

The domain name server may be a database responsible for managing the domain name space and resource information records. The database can be divided into sections called zones, and each domain name server can store one or more zones. After the domain name server receives the resource information processing request, it retrieves the data in the local area to give the response result.

It can be understood that the resource storage network can authorize the resource data or resource information to the domain name server by region. Among them, the division method of regions may be, for example, by country or region; or by city area, such as: A city area or B city area; or by enterprise, for example, A company corresponds to a domain name server, and B company corresponds to a domain name server. Corresponding to a domain name server, etc. This embodiment does not limit the division manner of the area. After the divided area is authorized to the area server, the relevant data such as the location of the data resources in the divided area can be queried through the area server.

It can be understood that in order to enhance the robustness of the domain name server, the redundancy of the storage area of the domain name server can be improved, that is, multiple different domain name servers can store the same area, so that multiple domain name servers can query response.

In order to achieve load balancing of domain name servers, when a domain name server contains a large database of domain name space and resource records, in order to improve efficiency, it can be divided into multiple areas, each area is independent of each other, and there is no overlapping content. . Then transfer some areas to other domain name servers to achieve load balancing.

In order to improve management efficiency, multiple domain name servers can also be merged, and the areas stored by these domain name servers can be de-duplicated, and then centralized in a single domain name server for storage and management.

It should be noted that, before the domain name resolver initiates a resource information processing request to the domain name server, at least one domain name server with access rights needs to be obtained. The target domain name server may be one or more domain name servers arbitrarily selected by the domain name resolver from at least one domain name server with access authority obtained. The domain name resolver selects the target domain name server by randomly selecting the domain name server according to the random selection rule, or by preferentially accessing the domain name server with a closer physical distance to itself, or by the domain name server with the lowest access delay.

In an optional embodiment, determining the target domain name server according to the chain resource processing request by the domain name resolver includes: using the domain name resolver to process the request according to the chain resource, and determining the target domain name server among the domain name servers discovered by the domain name resolver .

Wherein, the discovered domain name server may be at least one accessible domain name server that is gradually accumulated and determined during the process of processing the request by the domain name resolver.

Optionally, the way that the domain name resolver initiates the request to the domain name server may be that the domain name resolver analyzes the chain resource processing request initiated by the initiator. If the resource information corresponding to the chain resource processing request is not queried, or the resource information is insufficient Complete, the zone resolver will convert the chain resource processing request into a canonical request that the domain name server can parse, find the domain name server with open query authority, and initiate a request to it.

S230, through the domain name resolver, initiate a resource information processing request to the target domain name server; wherein, the resource information processing request is used to request the target domain name server to query the resource information based on the information of the resource data stored in the resource storage network to determine the resource information.

Exemplarily, the domain name resolver may directly initiate a resource information processing request to the target domain name server, or may broadcast the resource information processing request for the target domain name server to obtain after monitoring the resource information processing request.

It can be understood that when the target domain name server cannot respond to the resource information processing request, it can feed back to the domain name resolver other domain name servers that are not found by the domain name resolver in the resource resolution system. It should be noted that, when a new domain name server is added to the resource resolution system, the address of at least one domain name server needs to be obtained, so as to establish an association relationship.

In an optional embodiment, before receiving the resource information fed back by the target domain name server, the method further includes: by using the domain name resolver, if the optional domain name server connection address fed back by the target domain name server is received, according to the optional domain name server connection address and The corresponding domain name server establishes a connection, and updates it as a new target domain name server, and continues to perform the operation of initiating the resource information processing request until the resource information or failure result is received; wherein, the address space of the chain resource is divided into multiple domains, each Domain name servers are used to query resource information in one or more domains.

The optional domain name server may be a domain name server that is associated with the target domain name server and that the domain name resolver fails to actively discover.

Exemplarily, after the domain name resolver sends a resource information processing request to the target domain name server, if there is no corresponding resource information in the local cache of the target domain name server, or if the resource information processing request cannot be responded to, the target domain name server can query and Other domain name servers with associated relationship, and determine the optional domain name server from other domain name servers, and send the optional domain name server connection address to the domain name resolver. The domain name resolver establishes a connection with the corresponding domain name server according to the optional domain name server connection address, and updates it as a new target domain name server, and continues to perform the operation of initiating the resource information processing request until the resource information or failure result is received.

Optionally, the way for the target domain name server to determine the optional domain name server may be through DHT (Distributed Hash Table, distributed hash table) technology, distributed hash table to achieve recursive location and query of data resources; It is implemented by selectively recording the summary information of the zone stored by other neighboring domain name servers.

The address space of chain resources is divided into multiple zones, and each domain name server is used to query resource information in one or more zones; after the domain name server receives the resource information processing request, it can retrieve the data in the local zone to give Response result.

This optional embodiment establishes a connection with the optional domain name server by receiving the connection address of the optional domain name server fed back by the target domain name server, so as to realize the continuous expansion of the accessible domain name servers by the domain name resolver, and provide the domain name resolver with more The optional space of the domain name resolver and the domain name server improves the processing efficiency of the request.

It can be understood that the resource resolution system may include at least one domain name resolver. When a new domain name resolver is added to the resource resolution system, it is necessary to obtain the address of at least one domain name resolver in the resource resolution system to establish an association relationship. . Therefore, when the blockchain node initiates a chain resource processing request to the domain name resolver, if it is determined by the domain name resolver that the resource information query fails, other optional domain name resolvers are determined.

In an optional embodiment, after the resource information query is performed based on the information of the resource data stored in the resource storage network according to the chain resource processing request, the method further includes: if it is determined that the resource information query fails through the domain name resolver, determining other The optional domain name resolver, and feed back the connection address of the optional domain name resolver to the initiator of the chain resource processing request, so that the initiator can re-initiate the chain resource processing request to the optional domain name resolver.

The optional domain name resolver may be other accessible domain name resolvers deployed by the resource resolution system and having an associated relationship with the domain name resolver currently processing the request.

Exemplarily, if the domain name resolver processes the request according to the chain resource and fails to query the resource information, other optional domain name resolution servers can be determined, and the connection address of the optional domain name resolver is fed back to the initiator of the chain resource processing request. so that the initiator can re-initiate the chain resource processing request according to the optional domain name resolver. In addition, the initiator of the chain resource request can also store the connection address of the optional domain name resolver, so that subsequent requests can be initiated according to the optional domain name resolver.

In this optional embodiment, by determining the connection addresses of other optional domain name resolvers, the request initiator establishes a connection with the optional domain name resolver, so that the request initiator can continuously expand the accessible domain name resolvers, which is The request initiator provides more optional space, thereby improving the efficiency of the request processing by the domain name resolver and the domain name server.

It can be understood that, in order to increase the possibility of the request being answered, reduce the time consumed by the request, and avoid overloading the domain name server due to excessive requests. If the domain name resolver needs to access the domain name server, the status field is marked for each chain resource processing request to be processed. The domain name resolver generates a timeout period corresponding to the request when responding to the chain resource processing request. When the domain name resolver and the domain name server process the resource information processing request, if the processing time is not completed before the timeout period arrives, it will be forced to end and the corresponding response will be returned. error message to the initiator.

Optionally, in order to improve the selection efficiency of the domain name server by the domain name resolver, the domain name servers in the resource resolution system can be pre-grouped, and the domain name resolver broadcasts the resource information processing request, and only one of them is selected for each broadcast request. group, thereby improving the efficiency of server selection. In the process of query execution by the domain name server, when the query result is found or abnormally terminated, the query result or the accessible optional domain name server will be returned to the resource resolver.

S240, through the domain name resolver, receive the resource information fed back by the target domain name server.

In a specific embodiment, after acquiring the chain resource processing request, the domain name server checks whether there is resource information corresponding to the chain resource processing request in the local cache. If it exists, the resource information in the local cache will be directly fed back to the initiator; if it does not exist, certain rules, such as random selection rules, will select at least one domain name server from the set of accessible domain name servers, and report to the selected one. The domain name server sends a resource information processing request until a domain name server returns a response result. The resource parser analyzes the response result, and if the response is successful, feeds back the resource information of the response to the initiator. If the response contains other authorized nameservers, cache nameserver related information. If the response contains a domain name server authorization error, a server failure, or other anomalies, delete the domain name server information from the locally cached information, and re-select the domain name server. If none of the selected domain name servers can process the resource information processing request, and the total number of retries does not reach the upper limit of the threshold, other domain name servers are selected from the set of domain name servers to initiate the request again. If the total number of retries reaches the upper limit of the threshold, the request will be sent to the The initiator returned an error.

In an optional embodiment, after receiving the resource information fed back by the target domain name server through the domain name resolver, the method further includes: through the domain name resolver, performing at least one of the following checks on the resource information: validity check, validity check and Consistency check.

The check of the legitimacy of the resource information by the domain name resolver may include: the response result needs to contain the authoritative identity information of the domain name server, and needs to pass the verification. At the same time, the data structure of the response result needs to conform to the representation specification.

The check of the validity of the resource information by the domain name resolver may include: if the response arrival time exceeds the timeout time set when sending the request, the response result should be discarded.

The checking of the validity of the resource information by the domain name resolver may include: generating a unique ID (Identity document, identification number) for each request, and including the ID in the sent request. This ID should also be included in the response returned by the domain name server. The domain name resolver is responsible for confirming whether the ID in the response result matches the requested ID, so as to verify the validity of the resource information.

This optional embodiment improves the security of the acquired resource information by checking the legality, validity and matching of the resource information, and avoids the situation that the acquired resource information has security problems and causes losses to the requesting party. Fang Sheng.

S250. Respond to the chain resource processing request based on the resource information.

It can be understood that after receiving the chain resource processing request, the domain name resolver determines the target domain name server according to the chain resource processing request, and initiates a resource information processing request to the target domain name server. The target domain name server stores the resource data stored in the network based on the resource data. information, perform resource information query to determine resource information. In the above process, the domain name resolver may need to continuously access multiple domain name servers in order to find a target domain name server capable of processing the resource information processing request. In addition, the target domain name server also needs to send the resource information processing request to the resource storage network for processing and feedback the resource information. However, the above process increases the load of the domain name resolver and the domain name server, and the process of forwarding requests and feeding back results reduces the efficiency of obtaining resource information, thereby reducing the performance of the resource resolution system. Therefore, in the process of processing the chain resource processing request, the resource information fed back by the resource storage network can be locally stored.

In an optional embodiment, processing the request according to the chain resource and based on the information of the resource data stored in the resource storage network, performing a resource information query to determine the resource information includes: processing the request according to the chain resource, and performing resource information in a local cache If the resource information is queried in the local cache, it is determined to be resource information; if the resource information is not queried in the local cache, a resource information processing request is initiated to the resource storage network to query the resource information and determine the resource. information.

The resource resolution system can store the resource information fed back by the resource storage network locally. Exemplarily, the domain name server and/or the domain name resolver may locally cache the acquired resource information. When the resource information processing request is obtained, the domain name resolver queries the resource information in the local cache; if the domain name resolver finds the resource information corresponding to the resource information processing request, the resource information is directly fed back to the initiator; If the domain name resolver fails to find the resource information corresponding to the resource information processing request, it sends the resource information processing request to the domain name server.

The domain name server processes the request according to the resource information and performs a query in the local cache. If the domain name server queries the resource information corresponding to the resource information processing request, it sends the resource information to the domain name resolver, and the domain name resolver feeds back the resource information to The initiator; if the domain name server does not find the resource information corresponding to the resource information processing request, it sends the resource information processing request to the resource storage network to request the resource storage network to process the resource information processing request and feed back the resource information.

It should be noted that the data capacity of the resource information cached by the resource resolution system is small, but as the amount of cached resource information continues to increase, it is inevitable that the cache space will be filled. Therefore, a certain update or elimination mechanism may be adopted to periodically clear the cached resource information, thereby reserving more storage space for newly acquired resource information.

Exemplarily, the update time may be preset, the resource information within the update time is retained, and the resource information outside the update time is cleared. For example, the update time can be 7 days. That is, the resource data in the local cache that exceeds the update time for 7 days can be periodically cleared.

In this optional embodiment, the obtained resource information is cached locally, and the resource information can be queried in the local cache according to the chain resource processing request. If the local cache of the domain name resolver and the domain name server cannot be queried , when initiating a request to the resource storage network, the response speed to the resource information processing request is greatly improved, the load of the domain name resolver and the domain name server is reduced, the efficiency of obtaining resource information is improved, and the performance of the resource resolution system is improved. .

In the embodiment of the present disclosure, the domain name resolver in the resource resolution system determines the target domain name server according to the chain resource processing request; the domain name resolver initiates a resource information processing request to the target domain name server; and the domain name resolver receives feedback from the target domain name server. resource information. The above solution improves the efficiency of the cross-chain access data request initiated by the initiator by using the domain name resolver and/or the domain name server in the resource resolution system to process the chain resource processing request. Network direct query is more efficient.

It can be understood that the resource storage network can be a decentralized storage network based on blockchain technology, which can solve the problem of decentralized storage of domain names and resource records in the blockchain space. Based on decentralized storage technology, it can ensure the high availability and authenticity of blockchain space domain names and resource records.

It should be noted that the initiator and provider of cross-chain resources need to initiate requests based on the same cross-chain naming protocol, and the unified cross-chain naming protocol serves as the interoperability basis for cross-chain access resources between blockchain networks. The global dictionary table can be added and updated through smart contracts on the resource storage network based on blockchain technology. Other blockchain nodes publish resource information through this smart contract. The actual data of the global dictionary table is stored in the centralized resource storage network. Among them, the global dictionary table can use a global coding table for the positioning of the blockchain network, and declare the properties of the blockchain globally, such as frame type, name, etc., which are used to realize the basic information of mutual recognition of data.

In an optional embodiment, the resource information stored in the resource storage network includes: resource location data and resource permission data; the resource location data includes: the mapping relationship between the resource location identifier of the chain resource and the resource access address; the resource location identifier The string includes the domain name; the domain name is the domain name of the domain to which the blockchain node where the resource to be accessed belongs, and the resource access address includes the communication address of the blockchain node where the resource to be accessed is located.

The resource location identifier of the chain resource may be the location identifier of the chain resource in the blockchain network, and each data resource has a globally unique location identifier of the chain resource. There is a mapping relationship between the resource location identifier of the chain resource and the resource access address, and the corresponding resource access address can be obtained through the resource location identifier of the chain resource.

The resource to be accessed may be a resource that the originator of the chain resource wants to access or acquire. The resource right item data may include the name or identifier of the blockchain node that has the right to access the chain resource, etc.

Cross-chain resource access involves the interaction of data resources in different chains, and the resource location identifier is used to realize the unified location of these data resources. In a multi-chain blockchain network, each data resource has a unified and unique resource access address, which has a mapping relationship with the resource location identifier. The protocol definition of the resource access address can be preset. For example, the protocol definition of the resource access address can be: [specific type of chain:][//chain name][subchain/sidechain/parachain name][/contract name , method name and other parameter information].

The parameter items may include: resource name, resource execution parameters, account public key of the initiator of the cross-chain request, signature of the initiator of the cross-chain request, and the like. The resource execution parameters may include blockchain framework reserved parameters (the default value may be default), the contract name of the smart contract of the resource to be accessed, the method name and contract parameters of the smart contract of the resource to be accessed, etc.

For example: Suppose there is a blockchain network built using the underlying framework named Xuper, named hello_chain. There is a child chain/sidechain/parachain under this network called child_chain. On this child_chain, there is a smart contract that can only be executed by the wasm (webassembly) contract virtual machine. The smart contract is called counter and acts as a simple counter. The smart contract provides two methods, namely increase and getNumber. Calling the increase method will cause the value to be incremented by 1 each time. And calling the getNumber method will return the current value. If there is a blockchain network world_chain, you want to cross-chain access to the counter smart contract named counter on the child chain child_chain on the hello_chain network, and get the current value. Then the resource access address generated according to the pre-defined cross-chain protocol can be: "xuper://hello_chain/child_chain/module=wasm&contract_name=counter&method_name=getNumber".

Among them, xuper represents the reserved parameters of the blockchain framework, that is, the type of blockchain to be accessed is Xuper framework; hello_chain represents the name of the chain of the resource to be accessed is hello_chain; child_chain represents the name of the child chain/sidechain/parallel of the xuper chain of the resource to be accessed The chain name is child_chain; module=wasm indicates that the resource to be accessed is a smart contract, and the virtual machine used is wasm; contract_name=counter indicates that the contract name of the smart contract of the resource to be accessed is counter; method_name=getNumber indicates the smart contract of the resource to be accessed The method of the contract is named getNumber.

In an optional embodiment, the domain name space of the blockchain network includes multiple levels, and a tree-like structure is used for domain name storage. The nodes of the tree-like structure are used to store the labels of the corresponding level domain names. Corresponding to the data resources provided, the domain name of each node includes the label combination on the path from the current node to the root node of the tree structure; the domain name labels at each level of the domain name space include, from top to bottom: blockchain architecture name, blockchain Name of the operator to which the network belongs, blockchain name, blockchain node name, and resource name.

Among them, the domain name space of the blockchain network records the tree-structured domain name space and the data resources associated with these domain name spaces. Each node of the domain name space tree (including leaves, this embodiment makes no distinction between nodes and leaves, collectively referred to as "nodes") records a data resource record. The data resource may include resource type, access address, access protocol, version number, and permission requirements. For example, the resource type can be the type of the smart contract used, such as the smart contract using the wasm virtual machine; the access address can include IP and port numbers, etc.; the permission requirements can be, for example, different permission requirements corresponding to different methods in the smart contract .

Each node is used to store the label of the corresponding hierarchical domain name. The labels of non-sibling nodes can be the same, but the labels of sibling nodes are different. Among them, sibling nodes can be nodes with the same parent node. The label of the root node of the tree structure can be an empty label, that is, a label with a label length of zero. The full domain name of a node is the concatenation of the labels along the path from the current node to the root of the tree structure.

Exemplarily, the domain name can be named or saved in any case, for example, a node can be generated using the tag "A", or a node can be generated using the tag "a", but the two cannot be used as sibling tags. When generating a complete domain name, it may be necessary to splicing multiple tags. In this case, different tags can be separated by a marker, for example, the marker can be a dot (".").

Among them, the string representing the complete domain name can be called an absolute domain name. For example, the absolute domain name can be "channel.xxxxx.xchannel.". A string representing the start tag of an incomplete domain name may be referred to as a relative domain name. For example, "channel" in the absolute domain name "channel.xxxxx.xchannel." can be used as a relative domain name. If a domain name is contained within another domain name, the former is a subdomain of the latter. For example, channel.xxxxx.xchannel is a subdomain of xxxxx.xchannel and xchannel.

It should be noted that the domain name in the chain resource processing request initiated by the initiator can be represented by a label sequence. Each tag can be an eight-character string, and the maximum total length of the domain name is limited to 255 tags. Nameservers and name resolvers can compare labels in a case-insensitive manner.

Any uppercase and lowercase characters can be used in the domain name. However, domain names with the same spelling and different capitalization can be regarded as the same domain name. The name of the domain name starts with a letter and ends with a letter or number, and the characters in the middle can include letters, numbers and hyphens. The limit on the length of the domain name can be that the length of the label is no more than 63 characters. For example, the following string identifier can be used to describe a specific blockchain network in a cross-chain request: CHANNEL.XXX.XCHANNEL.

Optionally, this embodiment does not limit the tree structure used in the domain name space of the blockchain network, that is, it does not limit the use of a specific tree structure, or a specific method must be used in the tree structure. Locate labels to increase the versatility of the domain name space.

Among them, each node corresponds to the data resources provided by the blockchain, that is, each node can correspond to a domain name, each domain name can correspond to the data resources provided by the blockchain, and each data resource can correspond to a resource record , each resource record can correspond to a resource locator.

It should be noted that the domain name server may cache the structure of the domain name space related to the tree structure. The domain name server caches the resource record information in the domain name space of the specified blockchain network and refreshes it regularly. Resource record information is stored in a decentralized resource storage network based on blockchain technology.

In an optional embodiment, the resource query request will be forwarded by the domain name resolver to the domain name server to trigger a response. Domain name servers can respond to resource query requests or give reasons for errors. The initiator does not directly send the request to the domain name server, but first makes a resource query request to the domain name resolver. Depending on certain query conditions, the name resolver will forward the request to a name server suitable for processing the request, or give the reason for the error. For example, assuming that there are multiple chains under the domain name XXXX.XCHANNEL, CHAINX, CHAINY, and CHAINZ, the query requests of these three chains can be processed by three domain name servers ServerX, ServerY, and ServerZ respectively. Therefore, the corresponding request can be forwarded according to a specific chain. For example, for a query request for CHAINX.XXXX.XCHANNEL, the request can be sent to the domain name server ServerX for processing according to "CHAINX" in the domain name.

In an optional embodiment, the accessible resources provided by the blockchain network include: blockchain-supportable services and/or blockchain-readable data; blockchain-supportable services include at least one of the following: smart contracts , and methods accessible in smart contracts.

It is understandable that the originator of the cross-chain resource can initiate a chain resource access request for obtaining chain resources, a domain name query request for querying a domain name, and a permission query request for querying whether the chain resource has access rights to the resource resolution system.

In an optional embodiment, if the chain resource processing request is a chain resource access request, then according to the chain resource access request, based on the information of the resource data stored in the resource storage network, the resource information query is performed to determine the resource information including: The resource location identifier of the resource to be accessed in the chain resource access request, based on the resource location data stored in the resource storage network, the access address query is performed to determine the resource access address; wherein, the resource access address represents the resource to be accessed in the blockchain network. access entry in .

The chain resource access request may be an access or acquisition request of the initiator to the chain resource in the blockchain network.

The chain resource access request may include a resource location identifier and an access parameter, and the access parameter may include at least one of the following: resource name, resource execution parameter, initiator public key, and initiator signature.

The resource resolution system requests the resource storage network to determine the resource access address according to the chain resource access request according to the obtained chain resource access request. Exemplarily, the resource resolution system may parse the obtained chain resource access request to obtain a domain name resolution request, and initiate a domain name resolution request to the resource storage network. The domain name resolution request may include a resource location identifier and access parameters of the resource to be accessed. Based on the stored resource location data, the resource storage network queries the resource access addresses that have a mapping relationship with the resource location identifiers according to the resource location identifiers, so that the queried resource access addresses are fed back to the initiator based on the resource resolution system.

Optionally, after the resource resolution system obtains the chain resource access request, it can use the domain name resolver to query in the local cache according to the resource location identifier and access parameters in the chain resource access request. If the resource access address corresponding to the resource location identifier is not queried, the domain name resolver converts the chain resource access request to obtain a domain name server that can access the resource. For the identified domain name resolution request, the domain name server queries the local cache whether there is a resource access address corresponding to the domain name resolution request. If there is, the queried resource access address is directly fed back to the initiator through the domain name resolver; , the resource storage network processes the domain name resolution request to obtain the corresponding resource access address.

Exemplarily, after the initiator obtains the resource access address, the resource access address can be used to determine the access entry of the resource to be accessed in the blockchain network, and to access the resource to be accessed through the access entry.

The solution of this optional embodiment uses the resource location identifier of the resource to be accessed in the chain resource access request, and based on the resource location data stored in the resource storage network, performs access address query, realizes the determination of the resource access address, and realizes the initiation of The party can access and obtain cross-chain resources through the resource access address.

In an optional embodiment, if the chain resource processing request is a domain name query request, according to the domain name query request, based on the information of the resource data stored in the resource storage network, perform resource information query, to determine the resource information includes: querying according to the domain name For the resource access address in the request, based on the resource location data stored in the resource storage network, a domain name query is performed to determine the resource domain name; the resource domain name is the domain name of the domain to which the resource access address belongs.

The domain name query request may be a query request initiated by the initiator for the domain name of the blockchain node where the resource to be accessed belongs.

The domain name query request may include a resource access address. The resource access address may include the communication address of the blockchain node where the resource to be accessed is located.

According to the acquired domain name query request, the resource resolution system requests the resource storage network to determine the resource domain name according to the domain name query request. Exemplarily, the resource resolution system may parse the acquired domain name query request, and send the resolved domain name query request to the resource storage network. The domain name query request may include a resource access address. Based on the stored resource location data, the resource storage network performs domain name query according to the resource access address, so that the domain name of the domain to which the resource access address belongs is queried, and is fed back to the initiator as the resource domain name based on the resource resolution system.

Optionally, after the resource resolution system obtains the domain name query request, it can use the domain name resolver to query the local cache according to the resource access address in the domain name query request. If the domain name of the domain to which the resource access address belongs is queried, then The resource domain name can be directly fed back to the initiator; if the domain name of the domain to which the resource access address belongs is not queried, the domain name resolver converts the domain name query request to obtain a domain name query request recognizable by the domain name server, which is stored in the local cache by the domain name server. Query whether there is a resource domain name corresponding to the domain name query request, and if so, directly feed the queried resource domain name to the initiator through the domain name resolver; if not, the resource storage network will process the domain name query request to obtain The domain name of the domain to which the resource access address belongs.

The solution of this optional embodiment uses the resource access address in the domain name query request to perform domain name query based on the resource location data stored in the resource storage network, thereby realizing the determination of the domain name of the domain to which the resource access address belongs.

In an optional embodiment, if the chain resource processing request is a permission query request, according to the permission query request, based on the information of the resource data stored in the resource storage network, perform resource information query to determine the resource information includes: querying according to the permission The resource access address or resource location identifier of the resource to be queried in the request is based on the resource permission data stored in the resource storage network, and the permission query is performed to determine the resource permission; the resource permission is the permission control information of the resource being accessed.

Wherein, the permission query request may be a query request for the access permission of the chain resources in the blockchain network initiated by the initiator. For example, if the initiator wants to obtain the chain resource A of the blockchain network, it can query in advance whether it has the right to obtain or access the chain resource A, that is, whether the chain resource A authorizes the initiator and allows the initiator to access. The resource permission can be the permission control information that the resource is accessed.

The permission query request may include a resource access address or a resource location identifier of the resource to be queried. The resource permission data may include permission control information about the resource being accessed, for example, the name or identifier of the blockchain node that has permission to access the chain resource.

The resource analysis system requests the resource storage network to determine resource permissions according to the obtained permission query request according to the obtained permission query request. Exemplarily, the resource parsing system may parse the acquired permission query request, and send the parsed permission query request to the resource storage network. The permission query request may include a resource access address or a resource location identifier of the resource to be queried. Based on the stored resource permission data, the resource storage network queries whether the resource associated with the resource location identifier or resource access address has access permission according to the resource access address or resource location identifier, so that the resource permission result obtained by the query is fed back to the resource parsing system. Initiator.

Optionally, after the resource resolution system obtains the permission query request, it can use the domain name resolver to perform permission query in the local cache according to the resource location identifier and resource access address in the permission query request. The corresponding resource permission can be directly fed back to the initiator; if the resource permission corresponding to the permission query request is not queried, the domain name resolver converts the permission query request to obtain a permission query request identifiable by the domain name server. The domain name server performs the permission query in the local cache. If the resource permission corresponding to the permission query request is queried, the resource permission can be directly fed back to the initiator; if the resource permission corresponding to the permission query request is not queried, the resource permission will be based on The resource permission data stored in the resource storage network is queried to determine the resource permission.

Exemplarily, after the initiator acquires the resource permission, it can determine whether the resource to be queried can be accessed according to the resource permission result. If the resource authority does not have the access authority, the resource access address can be used to determine the access entry of the resource to be queried in the blockchain network, and the resource to be queried can be accessed through the access entry.

The solution of this optional embodiment implements the determination of the resource authority by performing authority query based on the resource authority data stored in the resource storage network according to the resource access address or resource location identifier of the resource to be queried in the authority query request, thereby realizing Determines whether the initiator has access to the resource to be queried.

FIG. 3 is a schematic diagram of a method for processing resources of a blockchain according to an embodiment of the present disclosure. The embodiment of the present disclosure is applicable to the situation of mutual positioning and acquisition of data resources between multiple chains. The method can be executed by a resource processing apparatus of a blockchain, and the apparatus can be implemented by means of hardware and/or software, and can be configured in an electronic device, and the electronic device can be a resource storage network. Referring to Figure 3, the method is applied to a resource storage network, and the method specifically includes the following:

S310. Obtain a resource information processing request; the resource information processing request is determined based on the chain resource processing request.

The chain resource processing request may be a request for cross-chain acquisition of data resources, query of domain name or query authority. The resource information processing request may be a processing request after parsing or converting the chain resource processing request by the resource parsing system. Among them, the chain resource processing request can be generated based on the transaction request initiated by the blockchain client.

It can be understood that the resource storage network is a decentralized storage network, and the resource storage network can be either a blockchain network implemented based on blockchain technology, or an ordinary distributed network implemented based on other technologies. When the resource storage network is a blockchain network based on blockchain technology, the resource resolution system can obtain resource information by initiating transaction requests to the resource storage network.

In an optional embodiment, the resource storage network is a blockchain network implemented based on the blockchain technology, and obtaining the resource information processing request includes: obtaining the resource information processing transaction request initiated by the blockchain client, and processing it as the resource information ask.

The resource information processing transaction request may be obtained by request analysis or conversion of the chain resource processing request by the resource analysis system, and is used for the transaction request initiated to the blockchain network.

Exemplarily, if the resource storage network is a blockchain network implemented based on blockchain technology, the resource parsing system parses or converts the resource processing request after obtaining the resource processing request, and obtains the resource information processing transaction request; The parsing system initiates a resource information processing transaction request to the resource storage network. After acquiring the resource information processing transaction request, the resource storage network performs resource information query based on the information of the resource data stored in the network to determine the resource information.

This optional embodiment uses the resource information processing transaction request initiated by the blockchain client as the resource information processing request method, and realizes the initiation of the transaction request for the resource storage network based on the blockchain technology, thereby realizing the The acquisition of resource information generated by the resource storage network based on blockchain technology.

It can be understood that the resource information processing request may be initiated after the domain name resolver or domain name server in the resource resolution system fails to query the local cache. The resource resolution system obtains the chain resource processing request, and determines the target domain name server according to the chain resource processing request through the domain name resolver in the resource resolution system; through the domain name resolver, a resource information processing request is initiated to the target domain name server; the target domain name server sends the resource storage The network initiates a request to request information based on resource data stored in the resource storage network, and perform resource information query to determine resource information.

The domain name resolver can process the request according to the chain resource and query the resource information in the local cache; if the domain name resolver queries the resource information in the local cache, it is determined as resource information; if the resource information is not queried in the local cache, Then initiate a resource information processing request to the domain name server; if the domain name server queries the resource information in the local cache, it is determined to be resource information; if the resource information is not queried in the local cache, it initiates a resource information processing request to the resource storage network, to perform resource information query and determine resource information. Therefore, the resource information processing request may be initiated by a domain name resolver or a domain name server.

In an optional embodiment, acquiring the resource information processing request includes: acquiring a resource information processing request initiated by a domain name resolver or a domain name server in the resource resolution system.

Among them, the domain name resolver can be used to parse the domain name and convert it into an IP (Internet Protocol, Internet Protocol) address, and the address of the domain name resolver can be pre-registered in the blockchain node for subsequent blockchain nodes. A chain resource processing request can be initiated to the domain name resolver according to the address of the pre-registered domain name resolver. Therefore, the address of at least one domain name resolver can be deployed in the blockchain node.

The domain name server may be a database responsible for managing the domain name space and resource information records. The database can be divided into sections called zones, and each domain name server can store one or more zones. After the domain name server receives the resource information processing request, it retrieves the data in the local area to give the response result.

S320. According to the resource information processing request and the information of the resource data stored in the resource storage network, query the resource information to determine the resource information.

The resource storage network may be a decentralized storage network, for example, the resource storage network may be a decentralized storage network based on blockchain technology. The resource data can be the accessible resources provided in the blockchain network, and the resource information can be the associated information of the accessible resources.

Exemplarily, the resource analysis system can process the request according to the chain resource, and initiate a resource information acquisition request to the resource storage network; after the resource storage network receives the resource information acquisition request, according to the acquisition request, based on the information of the resource data stored in the network. , to query the resource information to determine the resource information corresponding to the acquisition request.

S330, responding to the resource information processing request based on the resource information; the resource data is an accessible resource provided in the blockchain network, and the resource information is associated information of the accessible resource.

Exemplarily, after acquiring the resource information determined by the resource storage system, the resource resolution system may feed back the resource information to the initiator of the chain resource processing request.

Optionally, the resource resolution system may initiate a transaction request based on the blockchain client, so as to feed back resource information to the blockchain node to which the cross-chain resource user belongs.

The solution of the embodiment of the present disclosure determines the resource information by querying the resource information according to the obtained resource information processing request and the information of the resource data stored in the resource storage network; and responding to the resource information processing request based on the resource information. The above scheme maintains and manages multi-chain data resources by the decentralized storage network, obtains resource information from the decentralized storage network through the resource analysis system, and feeds it back to the cross-chain resource users, realizing the data between multiple chains. Mutual positioning and acquisition of resources; management based on the domain name mechanism enables blockchain nodes to flexibly publish and manage data resources provided by external chains. The multi-chain data resources are stored and maintained by the decentralized storage network, which can effectively prevent the data resources from being tampered with and can be maintained and updated; the technical solution of the present disclosure has strong versatility and high security and reliability.

On the basis of the above technical solutions, the present disclosure also provides an optional embodiment, in which the process of how a blockchain node performs resource registration in a resource storage network is improved. It should be noted that, for the parts that are not described in detail in the embodiments of the present disclosure, reference may be made to related expressions in other embodiments, and details are not described herein again.

Referring to a resource processing method of a blockchain shown in Figure 4, it includes:

S410. Receive a resource registration request initiated by the blockchain node.

It can be understood that the resource storage network can include three types of nodes, namely data holding nodes, storage nodes and blockchain nodes. Among them, the data holding node is the owner of the data, and is generally a participant in a blockchain network with storage requirements. Participants can encrypt, segment, and copy the blockchain space domain name, resource record information and access authorization control information corresponding to their own blockchain network and distribute them to storage nodes. The storage node has abundant idle storage resources and can provide storage services; it proves that it holds the data shards by responding to the challenge of the data holding node. Blockchain nodes constitute a blockchain domain name network, supporting the decentralized governance of the entire resource storage network. One or more smart contracts for registering and maintaining resource information can be deployed in the blockchain nodes of the resource storage network. For example, in a smart contract used for resource registration, a global dictionary table, that is, a global coding table, can be maintained for locating resource data in the blockchain network, and globally declaring the properties of the blockchain, such as frame type, name and other basic information used to realize mutual recognition of data. The global dictionary table can exist on the blockchain in the form of smart contracts, so that the blockchain network can use a unified naming method to encode the location identifier of resource data. The smart contracts deployed in the resource storage network can also check the health of all storage nodes in the resource storage network and give the measurement results. Metrics include, for example, replica retention proof challenge success ratio and effective heartbeat frequency. Smart contracts will adopt different strategies according to the measurement results, such as: healthy, data is recommended to be held; medium, data can be held; unhealthy, data may not be held. When conditions permit, the smart contract will schedule the storage network to migrate data shards from moderately healthy nodes/unhealthy nodes to healthy nodes.

Among them, the blockchain node can be the data initiator of the cross-chain resource access request, or the data holder of the cross-chain resource. The resource registration request may be a request initiated by the data holder who wants to register and store its own resources in the resource storage network.

Exemplarily, the data holder can initiate a resource registration request to the resource storage network through the blockchain client, so that the cross-chain resource initiator can access or obtain the registered resource data.

S420. Store the association information of the resource data in the resource registration request in the resource storage network; wherein the association information includes at least one of the following: resource location data and resource permission data.

Among them, the resource data can be the accessible resources provided by the blockchain nodes. The associated information may include resource location data and resource permission data.

The resource location data may include a mapping relationship between resource location identifiers of chain resources and resource access addresses. The resource permission data may include permission control information about the resource being accessed, for example, the name or identifier of the blockchain node that has permission to access the chain resource.

It can be understood that in the process of managing the resource data of the registered blockchain nodes by the resource storage network, the blockchain nodes can add, delete, modify and check the resource data registered by themselves. Correspondingly, the resource storage network can also actively A request to update the resource data is initiated to the blockchain node that registers the resource data, so as to realize the timely update of the resource data of the blockchain node.

It can be understood that, in order to ensure the security of the resource data of the data holding node during the resource registration process, the resource data in the resource registration request may be encrypted.

In an optional embodiment, storing the associated information of the resource data in the resource registration request in the resource storage network includes: encrypting and fragmenting the associated information of the resource data in the resource registration request to form encrypted fragments Copies; the encrypted shard copies are stored in the storage nodes in the resource storage network respectively.

The data holding node can encrypt, segment, duplicate and randomly group the associated information of the resource data requested for registration to form encrypted shard copies; the resource storage network can encrypt different storage nodes to generate encrypted shard copies and distribute them. to different storage nodes for storage. Using this encrypted storage method can ensure that the shards stored by each storage node are different, and the same storage proof cannot be reused between storage nodes, which can effectively resist single-copy attacks. The multi-copy multi-location storage method enables the storage network to have fault self-healing capability. An attacker cannot obtain the plaintext of resource data through the storage node, and it also requires huge costs for multiple storage nodes to obtain data at the same time.

This optional embodiment encrypts and shards the associated information of the resource data in the resource registration request to form encrypted shard copies; and stores the encrypted shard copies in storage nodes in the resource storage network, thereby improving The security of the resource data of the data holding node during the resource registration process is prevented, and the attackers are prevented from attacking the plaintext of the resource data of the storage node.

It should be noted that the mechanism to prevent storage cheating can be that the data holding node issues a challenge to the blockchain network, the storage node submits the storage proof to the blockchain network to answer the challenge, and the smart contract automatically verifies the response information. Provable storage nodes hold encrypted slices.

Optionally, the resource storage network may initiate a storage certificate retention request to each storage node according to a storage certificate mechanism, and receive a storage certificate fed back by the storage node based on the stored resource information.

It can be understood that the data holding node of the blockchain network can choose to authorize its own domain name and resource data to the resource resolution system, so that the initiator can access the authorized resource information through the resource resolution system.

In an optional embodiment, based on the authorization contract deployed by the resource storage network, the resource information of part or all of the stored resource data is authorized to the resource analysis system for query.

Among them, the authorization contract can be a smart contract with related functions that can process authorized resource data or domain names.

The data holding node of the blockchain network can choose to authorize the data file containing its own domain name and resource data to a certain domain name server in the resource resolution system. And the authorization behavior can be completed through the smart contract for authorization deployed in the resource storage network. When the resource information is authorized, the designated domain name server will have the ability to extract the corresponding resource information ciphertext from the resource-removing storage network, so as to complete the decryption operation of the resource information and obtain the original resource information.

Optionally, if a domain name and its corresponding resource data are authorized to be used by at least one domain name server, the information can be accessed by cross-chain resource users through the resource resolution system. On the contrary, if any domain name server is not authorized to use a domain name and its corresponding resource data, the information will be hidden from the resource storage network and cannot be accessed by users using the resource resolution system; if it exists in the local cache, it will be Hide after the cache period expires.

In this optional embodiment, the resource information of some or all of the stored resource data is authorized to the resource analysis system for query based on the authorization contract deployed on the resource storage network, so as to realize the authorization of the data holding node of the resource data. Therefore, it is convenient for the initiator to access the authorized resource information through the resource resolution system.

S430. Obtain a resource information processing request; the resource information processing request is determined based on the chain resource processing request.

S440. According to the resource information processing request and the information of the resource data stored in the resource storage network, query the resource information to determine the resource information.

S450 , responding to the resource information processing request based on the resource information; the resource data is the accessible resource provided in the blockchain network, and the resource information is the associated information of the accessible resource.

It should be noted that the execution sequence of S410-S420 in this embodiment may be before any steps of S430, S440 and S450, or between any steps of S430, S440 and S450, or between steps S430, S440 and S450. After any step of S450, this embodiment does not limit this.

By receiving the resource registration request initiated by the blockchain node, the solution of the embodiment of the present disclosure stores the associated information of the resource data in the resource registration request in the resource storage network, so that the blockchain node in the resource storage network can monitor its own resources in the resource storage network. Data registration, so as to facilitate the acquisition of registered resource data by cross-chain resource users. The resource data registered by the blockchain nodes is stored and maintained by the decentralized resource storage network, which can effectively prevent the resource data from being tampered with and can be maintained and updated.

It should be noted that the initiator and provider of cross-chain resources need to initiate requests based on the same cross-chain naming protocol, and the unified cross-chain naming protocol serves as the interoperability basis for cross-chain access resources between blockchain networks.

In an optional embodiment, the resource information stored in the resource storage network includes: resource location data and resource permission data; the resource location data includes: the mapping relationship between the resource location identifier of the chain resource and the resource access address; the resource location identifier The string includes the domain name; the domain name is the domain name of the domain to which the blockchain node where the resource to be accessed belongs, and the resource access address includes the communication address of the blockchain node where the resource to be accessed is located.

The resource location identifier of the chain resource may be the location identifier of the chain resource in the blockchain network, and each data resource has a globally unique location identifier of the chain resource. There is a mapping relationship between the resource location identifier of the chain resource and the resource access address, and the corresponding resource access address can be obtained through the resource location identifier of the chain resource.

The resource to be accessed may be a resource that the originator of the chain resource wants to access or acquire. The resource right item data may include the name or identifier of the blockchain node that has the right to access the chain resource, etc.

Cross-chain resource access involves the interaction of data resources in different chains, and the resource location identifier is used to realize the unified location of these data resources. In a multi-chain blockchain network, each data resource has a unified and unique resource access address, which has a mapping relationship with the resource location identifier. The protocol definition of the resource access address can be preset. For example, the protocol definition of the resource access address can be: [specific type of chain:][//chain name][subchain/sidechain/parachain name][/contract name , method name and other parameter information].

The parameter items may include: resource name, resource execution parameters, account public key of the initiator of the cross-chain request, signature of the initiator of the cross-chain request, and the like. The resource execution parameters may include blockchain framework reserved parameters (the default value may be default), the contract name of the smart contract of the resource to be accessed, the method name and contract parameters of the smart contract of the resource to be accessed, etc.

In an optional embodiment, the domain name space of the blockchain network includes multiple levels, and a tree-like structure is used for domain name storage. The nodes of the tree-like structure are used to store the labels of the corresponding level domain names. Corresponding to the data resources provided, the domain name of each node includes the label combination on the path from the current node to the root node of the tree structure; the domain name labels at each level of the domain name space include, from top to bottom: blockchain architecture name, blockchain Name of the operator to which the network belongs, blockchain name, blockchain node name, and resource name.

Among them, the domain name space of the blockchain network records the tree-structured domain name space and the data resources associated with these domain name spaces. Each node of the domain name space tree (including leaves, this embodiment makes no distinction between nodes and leaves, collectively referred to as "nodes") records a data resource record. The data resource may include resource type, access address, access protocol, version number, and permission requirements. For example, the resource type can be the type of the smart contract used, such as the smart contract using the wasm virtual machine; the access address can include IP and port numbers, etc.; the permission requirements can be, for example, different permission requirements corresponding to different methods in the smart contract .

Each node is used to store the label of the corresponding hierarchical domain name. The labels of non-sibling nodes can be the same, but the labels of sibling nodes are different. Among them, sibling nodes can be nodes with the same parent node. The label of the root node of the tree structure can be an empty label, that is, a label with a label length of zero. The full domain name of a node is the concatenation of the labels along the path from the current node to the root of the tree structure.

Exemplarily, the resource storage network determines the resource access address by querying the resource access address corresponding to the domain name to be resolved according to the mapping relationship between the resource location identifier and the resource access address in the stored resource location data. The character string of the resource locating identifier includes a domain name. Therefore, the corresponding resource locating identifier can be determined through the domain name to be resolved, so that the resource access address can be determined according to the resource locating identifier.

Exemplarily, the resource analysis system may initiate a permission query request to the resource storage network. The permission query request may include a resource access address or a resource location identifier of the resource to be queried. Based on the stored resource permission data, the resource storage network queries whether the resource associated with the resource location identifier or resource access address has access permission according to the resource access address or resource location identifier, so that the resource permission result obtained by the query is fed back to the resource parsing system. Initiator.

Exemplarily, after the initiator acquires the resource permission, it can determine whether the resource to be queried can be accessed according to the resource permission result. If the resource authority does not have the access authority, the resource access address can be used to determine the access entry of the resource to be queried in the blockchain network, and the resource to be queried can be accessed through the access entry.

The solution of this optional embodiment implements the determination of the resource authority by performing authority query based on the resource authority data stored in the resource storage network according to the resource access address or resource location identifier of the resource to be queried in the authority query request, thereby realizing Determines whether the initiator has access to the resource to be queried.
