Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application to assist in understanding, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
In the embodiment of the application, the lightweight node is similar to a full node, and deployment data of a block chain, such as an intelligent contract and a consensus mechanism, are deployed. Therefore, can participate in the transaction request interaction process of the block chain, but not store all block data. When the lightweight node needs to query the transaction data in the block chain, the block data can be acquired from other nodes in real time, and the verification is carried out by adopting a set mode. The lightweight node has lower requirements on the hardware configuration of the deployed equipment, can be integrated on the operating system level, controls the hardware in the terminal equipment, can interact with the upper application software, and provides block chain support for the functions of the application software.
Fig. 1 is a flowchart illustrating a blockchain-based transaction processing method performed by an activation server according to an embodiment of the present application. The embodiment is applicable to the case where the blockchain network processes the uplink transaction request of the lightweight node device. Typically, this embodiment may be applied to a case where the activation service allocates an associated blockchain network for the lightweight node device according to the number of the lightweight node devices, so that the associated blockchain network processes the uplink transaction request of the lightweight node device. The transaction processing method based on the blockchain disclosed in this embodiment may be executed by an electronic device serving as an activation server, and specifically may be executed by a transaction processing apparatus based on the blockchain, where the apparatus may be implemented by software and/or hardware and configured in the electronic device. Referring to fig. 1, the method for transaction processing based on a blockchain executed by an activation server according to this embodiment includes:
and S110, acquiring an activation request for applying to join the blockchain network, which is sent by the lightweight node equipment.
The activation request may be generated by the lightweight node device, and sent to the activation server, so as to apply for joining the blockchain network to the activation server.
The processing resources of the blockchain network and the capability of processing uplink transaction requests are limited, and if a large number of lightweight node devices are added into the blockchain network in an unordered and centralized manner, the transaction requests of the lightweight nodes may not be processed in time. In order to solve the above problem, in the embodiment of the present application, before the lightweight node joins the blockchain network, an activation application for applying for joining the blockchain may be sent to the activation server, so that the activation server allocates the blockchain network that can be used for processing the transaction request of the lightweight node device, and the problem that the blockchain network is unbalanced in load and high in processing pressure and is difficult to process the uplink transaction request in time due to centralized joining of a large number of lightweight node devices to the blockchain network is avoided.
And S120, distributing an associated block chain network for the lightweight node equipment, and processing the uplink transaction request initiated by the lightweight node equipment through the associated block chain network.
The uplink transaction request may be a write request, such as a transaction uplink request, a contract execution request, etc., or a read request, such as a transaction query request, a block query request, etc. For example, the activation server may assign the associated blockchain network to the lightweight node device, where the blockchain network may be an existing blockchain network or a new blockchain network created. Because the associated blockchain network is distributed for the lightweight node equipment by the activation server instead of enabling the lightweight node equipment to centrally access the blockchain network in an unordered manner at the same time, the blockchain network with calculation capability can be distributed for the lightweight node equipment, so that the blockchain network associated with the lightweight node equipment can timely and effectively process the uplink transaction request of the lightweight node equipment.
In this embodiment, after allocating the associated blockchain network to the lightweight node device, the activation server may store an association relationship between the lightweight node device and the blockchain network in the gateway device, where the gateway device may be at least one unified gateway. When the lightweight power-saving equipment generates an uplink transaction request, the uplink transaction request is sent to the gateway equipment, the gateway equipment sends the uplink transaction request to the block chain network associated with the lightweight node according to the pre-stored association relationship between the lightweight node equipment and the block chain network, and the block chain network processes the uplink transaction request.
In the embodiment of the application, in order to improve the search efficiency, a unified search service may be set for the search transaction request of the lightweight node. And constructing an inverted index by analyzing data in the block chain network so as to provide uniform search service. The lightweight node device can send the search request to a server providing unified search service, or send the search request to the server providing unified search service through the gateway device, and the unified search server provides search results to improve search efficiency and hide the existence of multiple networks for the lightweight node.
According to the technical scheme of the embodiment of the application, the associated block chain network is allocated to the lightweight node equipment in a targeted manner through the activation server, so that the problem that the block chain network load is large and the uplink transaction request of the lightweight node equipment cannot be processed in time due to the fact that a large number of lightweight node equipment access the block chain network in a centralized manner is solved, the processing resources of the block chain network are reasonably allocated, and the effect of processing the uplink transaction request of the lightweight node equipment in time is achieved.
Fig. 2 is a schematic flowchart of another block chain-based transaction processing method executed by an activation server according to an embodiment of the present application. This embodiment is an alternative proposed on the basis of the above-described embodiments. Referring to fig. 2, the transaction processing method based on a block chain provided in this embodiment includes:
s210, an activation request for applying to join the block chain network, which is sent by the lightweight node equipment, is obtained.
S220, comparing the number of the activated first total lightweight node devices in the existing block chain network with the number of second total lightweight node devices expected to be accommodated by the existing block chain network.
And determining the second total lightweight node equipment quantity according to the lightweight node equipment quantity expected to be accommodated by a single blockchain network and the existing blockchain network quantity. For example, the second total number of lightweight node devices may be the product of the number of lightweight node devices expected to be accommodated by a single blockchain network and the number of existing blockchain networks. The number of lightweight node equipment expected to be accommodated by the single blockchain network is determined according to the uplink time length of the single blockchain network.
For example, the uplink duration of the blockchain network may be a duration from when the blockchain network receives the transaction request to when the processing result is uplink stored, and may be determined by performing a pressure test on the blockchain network. Determining the number of lightweight node equipment expected to be accommodated by the blockchain network according to the uplink duration, so that the uplink duration of the blockchain network can be smaller than the uplink duration threshold when the number of activated lightweight node equipment in the blockchain network reaches the number of lightweight node equipment expected to be accommodated. For example, if the uplink duration of a certain blockchain network is less than the uplink duration threshold, it may indicate that the blockchain network has redundant computation, so that the number of lightweight node devices expected to be accommodated by the blockchain network may be increased; on the contrary, if the uplink duration of a certain blockchain network is greater than or equal to the uplink duration threshold, it may be said that the processing pressure of the blockchain network is large, so that the number of lightweight node devices expected to be accommodated by the blockchain network may be reduced.
And S230, if the number of the first total lightweight node devices is equal to or greater than the number of the second total lightweight node devices, controlling to create a new blockchain network, and establishing an association relationship between the lightweight node devices and the new blockchain network.
For example, if the number of the first total lightweight node devices is equal to or greater than the number of the second total lightweight node devices, it indicates that the current block chain network does not have the capability of timely processing the uplink transaction request of the newly added lightweight node device, and at this time, if the existing block chain network is still used to process the uplink transaction request of the lightweight node device, a problem may be caused that the processing of the uplink transaction request fails or cannot be timely processed. Therefore, in the embodiment of the present application, the activation service may generate a transaction request for organizing and creating a new blockchain network, control and create the new blockchain network, and introduce new computing power to improve the uplink transaction request processing capability of the entire blockchain network.
In this embodiment of the present application, the blockchain network may be an independent network, and a new blockchain network may be created through an existing node device according to a transaction request for creating a new blockchain network by an organization of an activation server. The blockchain may also be a three-dimensional blockchain network, i.e. a super-chain network, comprising at least two blockchain networks, e.g. nodes a, B and C form one blockchain network, and nodes E, D and F form another blockchain network. The three-dimensional block chain network comprises a basic chain and at least one parallel chain network. The three-dimensional blockchain network can create a transaction request of a new blockchain network according to the organization of the activation server, and construct a new parallel chain based on the basic connection so as to improve the processing capacity of the blockchain network.
Because the existing blockchain network does not have enough processing capacity to process the uplink transaction request of the newly added lightweight node equipment, the activation server allocates the created new blockchain network for the newly added lightweight node equipment, establishes the association relationship between the newly added lightweight node equipment and the new blockchain network, so that when the lightweight node equipment generates an uplink transaction request, the uplink transaction request is sent to the associated new blockchain network, and the uplink transaction request is processed in time by the associated new blockchain network. The allocation policy of the blockchain network may be: each blockchain network bears a basically consistent number of lightweight node devices, and the lightweight node devices can be all allocated to the newly created blockchain network before balance is achieved.
S240, if the number of the first total lightweight node devices is smaller than the number of the second total lightweight node devices, distributing a block chain network for the lightweight node devices from the existing block chain network, and establishing an association relationship between the lightweight node devices and the distributed block chain network.
For example, if the number of the first total lightweight node devices is less than the number of the second total lightweight node devices, it indicates that the currently existing blockchain network still has the capability of processing the uplink transaction request of the newly added blockchain node device, and therefore, the association relationship between the lightweight node devices and the existing blockchain network may be established. When the activation server establishes the association relationship between the lightweight node device and the existing blockchain network, the current processing capacity of each blockchain network can be considered, and the allocation is balanced. For example, the association relationship may be established with reference to the number of lightweight node devices that a single blockchain network is expected to accommodate. If the number of the lightweight node devices associated with one blockchain network is greater than or equal to the number of the lightweight node devices expected to be accommodated by the blockchain network, the association relationship between the blockchain network and other lightweight node devices is not established. If the number of the lightweight nodes associated with one blockchain network is smaller than the number of lightweight node devices expected to be accommodated by the blockchain network, the activation server allocates the blockchain network to the lightweight node device sending the activation request, and establishes an association relationship. Whether the association relationship between the blockchain network and the lightweight node device is established can also be determined by detecting the transaction processing capability of each blockchain network.
In this embodiment of the present application, the execution sequence of S230 and S240 is not specifically limited, and the executed steps may be determined according to a comparison result between the first total lightweight node device number and the second total lightweight node device number.
Fig. 3 is an overall block diagram of another specific implementation of a transaction processing method based on a blockchain executed by an activation server according to an embodiment of the present application. As shown in fig. 3, the activation server determines whether to allocate an existing blockchain network to the lightweight node device or to create a new blockchain network according to the number of activated lightweight node devices, and allocates the new blockchain network to the lightweight node device. And if the number of the activated lightweight nodes is larger than or equal to the number of the lightweight nodes expected to be accommodated by the existing blockchain network, creating a new blockchain network. If the number of the activated lightweight nodes is smaller than that of lightweight nodes expected to be accommodated by the existing blockchain network, the load condition in the blockchain network is measured through the load balancing server, and the blockchain network with the processing capacity is adaptively distributed to the lightweight node equipment. After the block chain network processes the data, the data can be gathered to establish an index, and a search result is provided for the lightweight node device through the unified search server.
According to the embodiment of the application, when the number of the first total lightweight node equipment is equal to or greater than the number of the second total lightweight node equipment, the creation of the new blockchain network is controlled, and the incidence relation between the lightweight node equipment and the new blockchain network is established, so that new calculation power is introduced, and the uplink transaction request is ensured to be processed in time. When the number of the first total lightweight node equipment is smaller than that of the second total lightweight node equipment, distributing a block chain network for the lightweight node equipment from the existing block chain network, and establishing an association relation between the lightweight node equipment and the distributed block chain network, so that the load of the existing block chain network is balanced, and the balance processing of the uplink transaction request is realized.
Fig. 4 is a flowchart illustrating a method for block chain based transaction processing performed by a lightweight node device according to an embodiment of the present application. The embodiment is applicable to the case where the block link network processes the uplink transaction request of the lightweight node device. Typically, this embodiment may be applied to a case where the activation service allocates an associated blockchain network for the lightweight node device according to the number of the lightweight node devices, so that the blockchain network processes the uplink transaction request of the lightweight node device. The block chain-based transaction processing method disclosed in this embodiment may be executed by an electronic device bearing a lightweight node, and specifically may be executed by a block chain-based transaction processing apparatus, which may be implemented by software and/or hardware and configured in the electronic device. The details, such as the noun explanation, etc., not described in detail in the embodiments of the present application are described in detail in the above embodiments. Referring to fig. 4, the block chain based transaction processing method performed by a lightweight node device according to this embodiment includes:
s310, an activation request for applying for joining the block chain network is generated.
The activation request may be generated by the lightweight node device, and sent to the activation server, so as to apply for joining the blockchain network to the activation server.
For example, the processing resources of the blockchain network and the capability of processing uplink transaction requests are limited, and if a large number of lightweight node devices are added to the blockchain network in an out-of-order centralized manner, the transaction requests of the lightweight nodes may not be processed in time. In order to solve the above problem, in the embodiment of the present application, before the lightweight node joins the blockchain network, an activation request for applying for joining the blockchain network may be generated first to request for joining the blockchain network, so as to avoid a problem that a large number of lightweight node devices collectively access the blockchain network in an unordered manner at the same time, which results in unbalanced load of the blockchain network, low processing capability, and incapability of timely processing an uplink transaction request of the lightweight node device.
S320, sending the activation request to an activation server to indicate the activation server to distribute the associated blockchain network for the local node equipment.
Exemplarily, an activation application for applying for joining a blockchain is sent to the activation server, so that the activation server allocates a blockchain network which can be used for processing the transaction request of the lightweight node device, and the problems that the blockchain network is unbalanced in load, large in processing pressure and difficult to process the uplink transaction request in time due to the centralized joining of a large number of lightweight node devices into the blockchain network are solved. The activation server may specifically allocate an associated blockchain network to the lightweight node device, where the blockchain network may be an existing blockchain network or a newly created blockchain network. Because the associated blockchain network is distributed for the lightweight node equipment by the activation server instead of enabling the lightweight node equipment to centrally access the blockchain network in an unordered manner at the same time, the blockchain network with calculation capability can be distributed for the lightweight node equipment, so that the blockchain network associated with the lightweight node equipment can timely and effectively process the uplink transaction request of the lightweight node equipment.
In this embodiment of the present application, after sending the activation request to the activation server, the method further includes: generating an uplink transaction request; and sending the uplink transaction request to the block chain network associated with the local node equipment to instruct the associated block chain network to process the uplink transaction request.
The uplink transaction request may be a write request, such as a transaction uplink request, a contract execution request, etc., or a read request, such as a transaction query request, a block query request, etc. The home node equipment may collectively send an uplink transaction request to its associated blockchain network to instruct the associated blockchain network to process the uplink transaction request. In an embodiment of the present application, the sending the uplink transaction request to the blockchain network associated with the local node device may include: and sending the uplink transaction request to gateway equipment to indicate the gateway equipment to distribute the transaction processing request to a block chain network associated with local node equipment according to the association relationship between the lightweight node equipment and the block chain network. For example, after allocating the associated blockchain network to the lightweight node device, the activation server stores the association relationship between the lightweight node device and the blockchain network in a gateway device, which may be at least one unified gateway. When the lightweight power-saving equipment generates an uplink transaction request, the uplink transaction request is sent to the gateway equipment, the gateway equipment sends the uplink transaction request to the block chain network associated with the lightweight node according to the association relationship between the lightweight node equipment and the block chain network, and the block chain network processes the uplink transaction request in time and in order.
According to the method and the device, the activation request is generated and sent to the activation server, so that the activation server can know the number of the currently activated lightweight node devices, and then the block chain network is allocated to the local node devices in a targeted manner, the problem that the block chain network is large in load and cannot process the uplink transaction request of the lightweight node devices in time due to the fact that a large number of lightweight node devices visit the block chain network in a centralized manner is solved, processing resources of the block chain network are reasonably allocated, and the effect of processing the uplink transaction request of the lightweight node devices in time is achieved.
