Description

Service processing method, device, node equipment and storage medium

The present application is a divisional application of a chinese patent application filed on 18/9/2020 of china patent office under application number 2020109828639 entitled "service processing method, device, node device, and storage medium", and the entire contents of the application are incorporated by application in the present application.

Technical Field

The present application relates to the field of block chain technologies, and in particular, to a service processing method and apparatus, a node device, and a storage medium.

Background

As blockchain technology evolves, blockchains are used by more and more enterprises and users. In using the blockchain, a user or an enterprise needs to register an account in the blockchain, and then a service request issued by the user or the enterprise to the blockchain network can be regarded as that the corresponding account is submitted to the blockchain network.

The process of the blockchain network executing the service request submitted by the user is as follows: after receiving a service request submitted by any account, storing the service request into a transaction pool; when an instruction for generating a new block is detected, selecting data including the service request from a transaction pool and packaging the data into the new block; broadcasting the new block to a consensus node in a block chain network, and performing consensus by the consensus node; after the consensus passes, a new block is added to the blockchain and the service indicated by the service request, such as a transfer service, is performed.

It can be seen that once a user submits a transaction to the blockchain network, the blockchain network performs the above process, and this may cause the transaction processing process to be repeated in some blockchain services, resulting in some unnecessary power consumption overhead. For example, in a service in which a plurality of accounts transfer to one account, for example, user a and user B transfer to user C, user a and user B submit transaction requests to the blockchain network respectively, and the blockchain network processes the requests of user a and user B respectively according to the above process, so as to transfer data resources in the accounts of user a and user B to user C. In summary, how to effectively perform service processing in a blockchain network becomes a hot issue of research.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The blockchain network is a novel application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism and encryption algorithm, and is essentially a decentralized database. The main concepts involved in blockchain networks include smart contracts, accounts, and transactions.

The intelligent contracts are the cores of the blockchain network and are equivalent to automatic agents in the blockchain network, and each intelligent contract corresponds to one contract address. When a transaction including a contract address is received, an intelligent contract corresponding to the contract address is activated and a blockchain network runs code corresponding to the intelligent contract.

An intelligent contract is associated with a contract account in a blockchain network. The contract account is one of the blockchain network accounts, and the blockchain network also comprises an external account which is controlled by the private key and does not have any code associated with the external account. And a contract account is an account assigned to an intelligent contract, controlled by the contract code and having a code associated therewith. The address of the external account number is determined by the public key, while the address of the contract account is determined when the smart contract is created. Each account has a corresponding balance that can be changed by exchanges with ethernet coins sent by other users. Information interaction can be carried out between the external account and the contract account and between the contract account and the contract account. Referring to fig. 1, an interaction diagram among an external account, a contract account, and an intelligent contract provided for an embodiment of the present invention is that a developer defines service logic of the intelligent contract through the contract account, that is, the developer deploys the intelligent contract in the contract account, and the external account may trigger execution of the intelligent contract corresponding to the contract account by sending a transaction to the contract account to complete the transaction between the accounts.

A transaction, which may also be understood as a service request, is an information exchange between one account and another account, and in colloquial terms, a transaction is a process in which one account sends a signed message packet to another account, and the blockchain network records and stores corresponding data. An identification of the sender of the transaction (i.e., the user owning the external account), an identification of the recipient of the transaction, the amount of resources of the transaction, and other data may be included in a transaction. Any one of the external accounts may create and sign a transaction, which may be a transfer transaction or a transaction related to a smart contract, such as a transaction used to create or trigger a smart contract, using its corresponding private key.

In an embodiment, the blockchain network may be regarded as a data sharing system, and referring to fig. 2, a schematic structural diagram of a blockchain network provided in an embodiment of the present invention is shown, the blockchain network may be regarded as a system for performing data sharing between nodes, the blockchain network may include a plurality of nodes 101, and the plurality of nodes 101 may refer to respective clients added to the blockchain network. Each node 101, while operating normally, may receive a transaction, otherwise referred to as a service request, entered into the blockchain network and maintain shared data within the blockchain network based on the received transaction. In order to ensure information intercommunication in the blockchain network, information connection can exist between each node, and information transmission can be carried out between the nodes through the information connection. For example, when any node in the blockchain network receives an input transaction, other nodes in the blockchain network acquire the transaction according to the consensus algorithm, and store the transaction as data in the consensus data, so that the data stored on all the nodes in the blockchain network are consistent.

In one embodiment, the data stored by each node in the blockchain network is stored on a blockchain, and each node maintains an identical blockchain. The block chain is composed of a plurality of blocks, the first block on the block chain is called a created block, the created block comprises a block head and a block main body, the block head stores a characteristic value, a version number, a timestamp and a difficulty value of a transaction, and the block main body stores the transaction; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the characteristic value of the transaction of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the information in the blocks is ensured.

In one embodiment, the obtaining of the transaction by the other nodes in the blockchain network according to the consensus algorithm may refer to: after receiving the transaction submitted to the blockchain network, any node in the blockchain network packs the transaction and other transactions into a new block; then broadcasting the new block to each node through information connection between the nodes, and carrying out consensus verification on the new block by each node through a consensus algorithm; after the verification is passed, the new block is connected to the block chain.

In the existing blockchain network, transactions received by nodes are submitted to the blockchain network by taking account individuals as units, so that the execution of multi-account cooperation services in the blockchain network is not facilitated, such as a many-to-one data resource transfer service or an intelligent contract calling service. Based on this, the embodiment of the present invention provides a service processing scheme, where the service processing scheme may be applied to a blockchain network, and the blockchain network may include at least one account group, where each account group includes at least two accounts; and if the accounts with the target quantity pass the authorization of the service request, executing the service indicated by the service request. The service request submitted to the block chain network by the target account carries the address identifier of the target account group, the service request can be regarded as being in account group unit, the node device performs service processing on the service request in account group unit, service processing modes in the block chain network are enriched, and multi-account cooperation service in the block chain network can be optimized.

Based on the service processing scheme, the embodiment of the invention provides a service processing system. Referring to fig. 3, which is a schematic structural diagram of a business processing system according to an embodiment of the present invention, the business processing system shown in fig. 3 may include a blockchain network 301 and at least one account group 302, each account group 302 may include at least one account 303, and each account 303 may refer to an external account in the blockchain network. Other accounts 304 not in any account group may also be included in the business processing system shown in fig. 3.

In one embodiment, the blockchain network 301 may include a plurality of node devices 3011, and each node device 3011 may be a terminal or a server. The terminal can be equipment such as a smart phone, a tablet computer, a notebook computer, a desktop computer, an intelligent sound box, an intelligent watch and the like; the server can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, and can also be a cloud server for providing basic cloud computing services such as cloud service, a cloud database, cloud computing, cloud functions, cloud storage, network service, cloud communication, middleware service, domain name service, security service, CDN, big data and artificial intelligence platform and the like.

In one embodiment, each account group 302 may be created by initiating an account group creation request to the blockchain network, where the account group creation request may carry a plurality of account identifiers, and the node device 3011 combines the account from which the account group creation request is initiated and the account indicated by each account identifier in the plurality of account identifiers in the account group creation request into one account group. In addition, after an account group is successfully created, the node device 3011 may assign a unique address identifier to the account group.

Also, the node device 3011 may set the account initiating the account group creation request as an account having a management authority for the account group, and the account having the management authority may manage the account group, such as deleting an account in the group, adding a new account, or sending a service request to the blockchain network in units of account groups. The sending of the service request to the blockchain network by taking the account group as a unit is to send the service request carrying the address identifier of the account group to the blockchain network.

In one embodiment, an account 303 with management authority in any account group may submit a service request carrying an address identifier of the account group to which the account group belongs to the blockchain network through a user terminal used by the account 303. The user terminal used by the account 303 may be a node device in the blockchain network 301, or may not be a node device in the blockchain network 301 but may communicate with any node device in the blockchain network 301. It is assumed in fig. 3 that the user terminal used by account 303 is not a node device in the blockchain network 301. The user terminal can be terminal equipment such as a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart sound box and a smart watch.

After the blockchain network 301 receives the service request, any node device 3011 in the blockchain network executes the service processing scheme described above, so as to implement execution of the service indicated by the service request.

Based on the service processing system, the embodiment of the invention provides a service processing method. Referring to fig. 4, a flow chart of a service processing method according to an embodiment of the present invention is schematically shown. The traffic processing method shown in fig. 4 may be performed by any node device in the blockchain network. The service processing method shown in fig. 4 may include the following steps:

step S401, receiving a service request sent by a target account to a node device, wherein the service request carries an address identifier of a target account group to which the target account belongs.

In one embodiment, the target account group is generated from an account group creation request submitted to the node device by the target account. In a specific implementation, a node device receives an account group creation request submitted by a target account, wherein the account group creation request may include at least one account identifier; and after the verification of the account group creation request by the node equipment is passed, forming a target account group by the target account and the accounts indicated by each account identifier in the at least one account identifier, and allocating address identifiers for the target account group. An account group is uniquely identified by its corresponding address identifier.

In one embodiment, the node device may group the target account and the account indicated by each account identifier in the at least one account identifier into a target account group, which may include: sending a creation notification to the account indicated by each account identifier of the at least one account identifier; and forming a target account group by the account, which is indicated by each account and has input a confirmation instruction for the creation notification, and the target account. The creation notification received by any account may include an account group creator, that is, a target account, and an account other than the own account in at least one account identifier.

That is, before forming a target account and an account indicated by at least one account identifier into a target account group, the node device may notify a creation notification of the account group indicated by each account identifier in the at least one account identifier to notify that each account is to be added to one account group; if any account agrees to be added into the account group, a confirmation instruction can be input, and further, the node device forms the target account group by the account into which the confirmation instruction is input and the target account, so that each account can select whether to be added into a certain account group by itself, and the security of data resources in the account can be ensured.

In one embodiment, the target account may be any one of a group of target accounts; alternatively, the target account may be an account having administrative rights to a group of target accounts. The management authority may refer to adding an account to the target account group, deleting an original account, or dissolving the target account group, or the like.

Optionally, after the node device forms a target account group with the target account and the account indicated by the at least one account identifier, an account having a management right for the target account group may also be set as the target account. That is, the node device may default the account from which the account group creation request originated as an account having administrative rights to the account.

In one embodiment, after an account group is successfully created, the actual payer is a member of the group with a service request initiated by the account group. For example, a data resource transfer-out service initiated by taking an account group as a unit should be an account in the account group.

Step S402, at least one account related to the service request in the target account group is obtained according to the address identification, and notification information of authorization verification is sent to each account in the at least one account.

As can be seen from the foregoing, one account group corresponds to one unique address identifier, and the node device may acquire all accounts included in the target account through the address identifier of the target account. In step S402, the acquiring at least one account related to the service request in the target account group according to the address identifier includes: and acquiring all accounts in the target account group according to the address identification, and selecting at least one account related to the service request from all the accounts.

And selecting at least one account related to the service request according to different services indicated by the service request. In one embodiment, if the service indicated by the service request is a data resource transfer-out service, and the service request carries a transfer-out party account, at least one account related to the service request is an account in the target account group, which is matched with the transfer-out party account. For example, the target account group includes an account a, an account B, and an account C, the service indicated by the service request is a data resource transfer-out service, and the transfer-out party accounts carried in the service request are a user a and a user C, so that the user a and the user C in the target account group can be used as accounts related to the service request.

In other embodiments, if the service indicated by the service request is a multi-account collaboration service, such as invoking an intelligent contract, the at least one account associated with the service request may refer to all accounts in the target account.

In one embodiment, after determining at least one account related to the service request, notification information of authorization verification may be sent to each account of the at least one account, where the notification information is used to instruct each account to perform authorization verification on the service request.

In one embodiment, each account may verify the service request with a digital signature. Optionally, the digital signature means that each account has a pair of signature keys, which are a public key and a private key, respectively, the public key is disclosed in the blockchain network, and the private key is stored by the account itself. When the service request needs to be verified, any one account uses the respective private key to sign the service request; and the node equipment verifies the signed service request by adopting the public key corresponding to each account, and if the service request passes the verification, the authorization verification of any account on the service request is determined to pass.

In one embodiment, the service request sent by the target account to the blockchain network in step S401 may also carry a digital signature of the target account, that is, it is equivalent to that the authorization verification of the service request is completed when the target account sends the service request. Based on this, in order to save power consumption overhead, if there is a target account in at least one account related to the service request, the node device may send an authorization verification notification to other accounts except the target account in the at least one account before sending notification information of authorization verification to each account in the at least one account.

Step S403, if the authorization verification of the service request by the target number of accounts in the at least one account passes, executing the service indicated by the service request.

In one embodiment, the target quantity is related to a total quantity of accounts for the service indicated by the service request and the at least one account. In a specific implementation, if a service indicated by the service request is a data resource transfer-out service, and the service request carries a transfer-out party account identifier of the data resource transfer-out service, in this case, at least one account refers to an account in a target account group that is matched with the transfer-out party account identifier carried in the service request, and the target number may be equal to the total number of accounts of the at least one account. In short, if the service indicated by the service request is a data resource transfer-out service and the transfer-out party account is at least one account in the target account group, it is required that each account in the at least one account performs signature verification on the service request, and then the data resource can be transferred out from each account.

In other embodiments, if the service indicated by the service request is a multi-account collaboration service, such as intelligent contract invocation, in this case, the at least one account may refer to all accounts in a target account group, and the target number may be determined based on an account number proportion threshold corresponding to the multi-account collaboration service and the total number of accounts of the at least one account. In a specific implementation, the node device may preset that the executed multi-account collaboration service requires authorized signing on accounts greater than or equal to the proportion threshold among the accounts related to the service. For example, if the percentage threshold of the number of accounts corresponding to a certain multi-account collaboration service is 70%, indicating that, in the accounts related to the multi-account collaboration service, if more than or equal to 70% of the accounts perform authorized signature on the multi-account collaboration service, the multi-account collaboration service may be executed.

Based on this, the determining the target number based on the multi-account collaboration service and the total number of accounts of the at least one account includes: acquiring an account quantity proportion threshold corresponding to the multi-account cooperative service; determining a target number based on the proportional threshold and the total number of accounts. For example, assuming that the total number of accounts of at least one account related to a certain multi-account collaboration service is 10, and the percentage threshold of the number of accounts corresponding to the multi-account collaboration service is 50%, if any 5 accounts among the 10 accounts are authorized to be signed, the multi-account collaboration service may be executed.

In one embodiment, the executing the service indicated by the service request includes: selecting at least one service including the service and packaging the service into a target block to be verified; informing a consensus node in a block chain network to verify the target block to be verified; and if the target block to be verified is verified, executing the service indicated by the service request, and linking the target block to the block chain.

Based on the foregoing service processing method, an embodiment of the present invention provides another service processing method. Referring to fig. 5, a schematic flow chart of another service processing method according to an embodiment of the present invention is shown. The service processing method shown in fig. 5 may be executed by any node device in the blockchain network, and may specifically be executed by a processor of the node device. The service processing method shown in fig. 5 may include the following steps:

step S501, receiving an account group creation request submitted by a target account.

In one embodiment, the account group creation request may include at least one account identifier, each account identifier uniquely indicates one account, and the target account carries at least one account identifier in the account group creation request, indicating that the target account wants to select to form one target account group with the account indicated by each account identifier in the at least one account identifier. Optionally, when the target account group selects at least one account identifier, an account identifier having business with the target account group may be selected from accounts of the multiple block chain networks, for example, the target account is account a, and account a often has a cooperative relationship with account B and account C, so that account a may carry the account identifiers of account B and account C in the account group creation request.

As another optional embodiment, for the many-to-one data resource transfer service, if the target account is a transfer party account in the data resource transfer service, the target account may select that other transfer party accounts in the many-to-one data resource transfer service are carried in the account group creation request; or, if the target account is the transferring party account in the data resource transferring service, the target account may also select other transferring party accounts in the many-to-one data resource transferring service to be carried in the account group creation request.

In other embodiments, the target account may also randomly select at least one account identifier from the plurality of blockchain network accounts to be carried in the account group creation request.

Step S502, after the verification of the account group creation request is passed, the target account and the accounts indicated by each account identifier in the at least one account identifier form a target account group.

Assuming that in fig. 5, the accounts indicated by each account id in the at least one account id are account a and account B, respectively, the blockchain network forms a target account group from the target account, account a, and account B.

Step S503, allocating address identification for the target account group, and setting the account having management authority for the target account group as the target account.

In one embodiment, after the verification of the account group creation request by the node device is passed, the target accounts and the accounts indicated by each account identifier form a target account group, and address identifiers are allocated to the target account group. And setting the target account as an account having management authority to the target account group by default, or setting the target account as a management account of the target account group.

After the setting is successful, the target account may manage the target account group, where the managing may include updating an account in the target account group, such as deleting an account of the target account group or adding a new account in the account group, and the managing may further include sending a service request carrying an address identifier of the target account group to the blockchain network.

In a specific implementation, when the target account updates the intra-group account of the target account group, the node device may perform: receiving an intra-group account updating request submitted by a target account, wherein the intra-group account updating request is used for indicating that a new account is added in the target account group or an existing account in the target account group is deleted; and after the verification of the intra-group account updating request is passed, the node equipment updates the accounts included in the target account group according to the intra-group account updating request.

Optionally, if the intra-group account update request indicates that a new account is added to the target account group, the intra-group account update request may carry an account identifier of the new account, and after the intra-group account update request is verified, the new account is added to the target account group; if the intra-group account updating request indicates to delete an existing account in the target account group, the intra-group account updating request may carry an account identifier of the account to be deleted, and after the intra-group account updating request is verified, the node device may delete the account indicated by the account identifier from the target account group.

In one embodiment, the target account may also transfer administrative rights to any one of the accounts within the target account group. In specific implementation, the node equipment receives a management authority transfer request sent by a target account; and after the node equipment passes the verification of the management authority transfer request, updating the account with the management authority from the target account to the account indicated by the management authority transfer request. For example, the target account group includes an account a, an account B, and an account C, where the account a is an account with management authority, the account a may submit a management authority transfer request to the blockchain network to transfer the management authority to the account C, and after the management authority transfer, the account C is an account with management authority in the target account group.
