The service providing method provided by the embodiment of the invention is described in detail below based on the above block chain network service system.
Fig. 2 is a flowchart illustrating a service providing method according to an embodiment of the present invention. As shown in fig. 2, the method mainly comprises the following steps:
s201, receiving a request message and identity information sent by an application access party through a block chain interaction module, and transmitting the request message and the identity information to corresponding target block chain networks in a plurality of block chain networks; the identity information is obtained by applying the application access direction to centralize the identity network application.
In the embodiment of the present invention, in the blockchain network service system, the blockchain interaction module of the blockchain service access layer may receive the request message and the identity information sent by the application access party, and transmit the request message and the identity information to the corresponding target blockchain network in the plurality of blockchain networks.
It should be noted that, in the embodiment of the present invention, the block chain interaction module may first receive the request message and the identity information transmitted by the application access party, and further transmit the request message and the identity information to the target block chain network. The block chain network can provide corresponding service for the application access party by using the request message in a plurality of block chain networks in the target block chain network.
It should be noted that, in the embodiment of the present invention, before sending the request packet and the identity information to the blockchain interaction module, the application access side needs to apply for obtaining the identity information of the application access side from the decentralized identity network.
It should be noted that, in the embodiment of the present invention, the request message may be an uplink data or an inquiry message. Of course, other information related to the requested service may also be present. The specific embodiments of the present invention are not limited.
It is understood that, in the embodiment of the present invention, the blockchain interaction module needs to determine the target blockchain network from the plurality of blockchain networks before transmitting the request message and the identity information to the corresponding target blockchain network.
Specifically, in the embodiment of the present invention, before the blockchain interaction module transmits the request message and the identity information to the target blockchain network, after receiving the request message and the identity information, when the request message is uplink data, the balanced fault-tolerant module of the blockchain service access layer selects one blockchain network from the multiple blockchain networks as the target blockchain network according to the load state of each blockchain network in the multiple blockchain networks.
It is understood that, in the embodiment of the present invention, if the application access side initiates an uplink request, i.e. uplink data is transmitted to the block chain interworking module to request uplink data, a block chain network needs to be allocated for uplink data for data uplink. Therefore, the balanced fault-tolerant module can select the block chain network most suitable for the uplink from the load states of all the block chain networks to serve as the corresponding target block chain network.
It should be noted that, in the embodiment of the present invention, the load status of the blockchain network may include connectivity, processing capability, and current queuing condition of the blockchain network, and of course, may also include other related information, and the embodiment of the present invention is not limited.
Specifically, in the embodiment of the present invention, before the blockchain interaction module transmits the request message and the identity information to the target blockchain network, after receiving the request message and the identity information, when the request message is a query message, the blockchain interaction module searches for a target network identifier corresponding to the target blockchain network from other received information sent by the application access party; when the block chain interaction module does not find the target network identifier, the target network identifier is found out from a stored database by utilizing the query message through the database module; and receiving the target network identification transmitted by the database module through the block chain interaction module. Correspondingly, the transmitting the request message and the identity information to a corresponding target block chain network in a plurality of block chain networks through the block chain interaction module comprises: and transmitting the query message and the identity information to a target block chain network through a block chain interaction module according to the target network identifier.
It should be noted that, in the embodiment of the present invention, the target blc actually applies the blc to which the access-related uplink data is linked before the query, so that the query message needs to be sent to the target blc during the query process to perform the data query.
It can be understood that, in the embodiment of the present invention, when the application access side initiates the data query request, the application access side may send not only the query packet and the identity information, but also a target network identifier corresponding to the target block chain network, and the block chain interaction module may receive the target network identifier, thereby determining the target block chain network, and finally performing data query through the target block chain network. Of course, the application access side may not send the target network identifier, and at this time, the database module queries the target network identifier from the stored data by using the query message and sends the target network identifier to the block chain interaction module.
It should be noted that, in the embodiment of the present invention, if the database module does not find the target network identifier from the data stored in the database module according to the query packet, the information that is not found needs to be returned to the application access party.
S202, the validity of the identity information is requested to be verified from the decentralized identity network through the target block chain network.
In the embodiment of the invention, after receiving the request message and the identity information of the application access party forwarded by the block chain interaction module, the target block chain network can request the DId network to verify the validity of the identity information.
It should be noted that, in the embodiment of the present invention, the target block chain network includes multiple peer nodes, and the peer nodes may request the DId network to verify the validity of the identity information.
It can be understood that, in the embodiment of the present invention, the application access side applies for the corresponding identity information from the DId network, and the DId network also stores the identity information of the application access side. When the peer node of the target block chain network requests the DId network to verify the identity information, the DId network can actually perform related matching comparison and other processing on the identity information, so as to determine whether the identity information is legal or not, and send verification result information to the peer node of the target block chain network. Specifically, when the DId network determines that the identity information is legal, a verification passing message is returned to the target block chain network, when the target block chain network receives the verification passing message, the target block chain network can know that the identity information is legal, so that subsequent service operation is performed, correspondingly, when the target block chain network determines that the identity information is illegal, the DId network returns a verification failure message to the target block chain network, and when the target block chain network receives the verification failure message, the target block chain network can know that the identity information is illegal, so that the subsequent service operation is terminated.
And S203, when the identity information is verified through the decentralized identity network, providing corresponding service to the application access party through the target block chain network by using the request message.
In the embodiment of the invention, when the DId network passes the authentication of the identity information, the target blockchain network can provide corresponding services to the application access party by using the request message.
Specifically, in the embodiment of the present invention, providing a corresponding service to an application access party by using a request packet through a target blockchain network includes: when the request message is uplink data, signing and uplink data through a target block chain network; and when the uplink is successful, the first feedback operation and/or the second feedback operation are/is executed through the target block chain network, and the uplink service is completed.
It should be noted that, in the embodiment of the present invention, the request message is uplink data, and actually, the target block chain network needs to uplink the uplink data, that is, add the uplink data to the block chain of the target block chain network.
It should be noted that, in the embodiment of the present invention, when the target blockchain network fails to uplink the uplink data, the failure result may be returned to the equalization fault-tolerant module, and the equalization fault-tolerant module may continue to select one blockchain network from the multiple blockchain networks again to uplink the uplink data again. In addition, if all the blockchain networks fail to uplink the uplink data, the balanced fault-tolerant module can return the results of all the uplink failures to the application access side.
Specifically, in the embodiment of the present invention, when the uplink is successful, the first feedback operation is performed by the target block chain network, including: transmitting the uplink result and a target network identifier corresponding to the target block chain to a block chain interaction module through a target block chain network; and transmitting the uplink result and the target network identifier to the application access party through the block chain interaction module to complete the first feedback operation. When the uplink is successful, executing a second feedback operation through the target block chain network, wherein the second feedback operation comprises the following steps: and transmitting the uplink result, the uplink data and the target network identifier to a database of the database module for storage through the target block chain network, and finishing the second feedback operation.
It is understood that, in the embodiment of the present invention, after the target blk network successfully uplinks the uplink data, the target blk network may transmit the successful uplink result and the target network identifier to the blk network interworking module, and the blk network interworking module may forward the target blk network identifier to the application access party, so that the application access party knows that the uplink data is successfully uplinked and the specific blk network to which the uplink data is uplinked. Of course, the target block chain network may also transmit the uplink result, the uplink data, and the target network identifier to the database module for data storage, so as to provide support for services such as subsequent queries.
Specifically, in the embodiment of the present invention, if the request packet is an inquiry packet, the method for providing a corresponding service to the application access party by using the request packet through the target block chain network includes: performing query operation according to the query message through a target block chain network, and transmitting the queried target data to a block chain interaction module; and transmitting the target data to the application access party through the block chain interaction module.
It is understood that, in the embodiment of the present invention, the request packet is a query packet, and the target blockchain network may perform a query operation according to the query packet, so as to provide the queried target data to the application access party. The data interaction between the target block chain network and the application access party is realized by forwarding through a block chain interaction module.
Fig. 3 is a flowchart illustrating an uplink procedure according to an embodiment of the present invention. As shown in fig. 3, the application access side first applies for identity information from the DId network, and then initiates an uplink request to the block chain service access layer. The balanced fault-tolerant module of the block chain service access layer firstly selects a block chain network according to the network connectivity, the processing capacity and the current queuing condition of each block chain network in a plurality of block chain networks, and selects a target block chain network from the block chain networks. And the block chain service access layer calls the determined target block chain network and transmits the uplink data and the identity information sent by the application access party to the target block chain network. The target block chain network carries out validity verification on the identity information based on the DId network. If the identity information of the application access party is legal, the target block chain network signs and chains the chain data, and after the chain is successfully linked, the chain result and the target network identification of the target block chain network are returned to the application access party through the block chain interaction module, and/or the target block chain network directly stores the chain result, the target network identification and the chain data in a database. And if the identity information of the application access party is illegal, the target block chain network returns the information of the identity authentication failure to the application access party through the block chain interaction module. In addition, if the uplink fails, the target blockchain network returns the information of the uplink failure to the balanced fault-tolerant module through the blockchain interaction module so as to reselect a new blockchain network for uplink.
Fig. 4 is a flowchart illustrating a query process according to an embodiment of the present invention. As shown in fig. 4, when the block chain interaction module receives a target network identifier of a target block chain network sent by an application access party, the received query message and the received identity information are sent to the target block chain network according to the target network identifier. And the target block chain network carries out validity verification on the received identity information based on the DId network, and when the verification is passed, the target block chain network carries out query operation by using the received query message and returns a query result to the application access party through the block chain interaction module. When the application access side does not send the target network identification, the database module searches the target network identification from the database according to the query message, and the block chain interaction module can transmit the received query message and the identity information to the target block chain network so as to perform subsequent identity authentication and query operations. Of course, if the database module finds the target network identifier, the database module returns the information which is not found to the application access party.
