Detailed Description
In order to make the technical solutions in the present specification better understood by those skilled in the art, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only some embodiments of the present specification, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.
The blockchain is a distributed network data storage technology constructed by utilizing an encryption algorithm and a point-to-point transmission technology, and has the characteristics of decentralization, tamper resistance, traceability and the like. In a blockchain, data may no longer be stored in a centralized hardware or administrative authority, but rather maintained together by blockchain nodes that are entitlement and obligation peers; data may be recorded on multiple nodes of a system of blockchain technical components enabling any node to view data stored in a local blockchain at any time; once the data is verified and added to the blockchain, the data can be permanently stored, and the data cannot be tampered by utilizing a consensus algorithm and a hash chain type data storage technology, so that the safety and the authenticity of the data are ensured. With point-to-point network technology, individual block link points can be grouped into a distributed network, where each node is equally located. Transaction data may be communicated over a network to various nodes, which may verify the validity of the transaction and join the corresponding block to its local block chain if the verification passes. The blockchain node can locally store a complete transaction ledger copy, namely a local blockchain, so that the transaction ledger copy of the node synchronously completes updating, thereby achieving decentralization consensus.
For blockchain networks that include, for example, 1000 or more blockchain nodes, the blockchain network may be organized using, for example, a tree topology due to the large number of nodes therein. In particular, the blockchain node that initiates the broadcast of the application layer message may transmit the application layer message to its next layer of neighboring nodes, while at least one of the nodes may continue to transmit the application layer message to its next layer of neighboring nodes, and so on, until the application layer message is broadcast to all or most of the blockchain nodes in the blockchain network. In some embodiments, to maintain stability and reliability of the tree topology, the number of neighbor nodes of its next level corresponding to each blockchain node may be equal, e.g., 2, 4, or 8, etc. The number of its next-tier neighbor nodes corresponding to each node in the tree topology may be determined based on parameters such as the total number of blockchain nodes in the blockchain network and the desired broadcast depth (the longest broadcast link or the largest number of broadcast hops that may pass in a broadcast). In such a blockchain network, when an application layer message is to be broadcast, it is possible for the application layer message to be transmitted in hops between blockchain nodes. Depending on the depth of the tree topology and the merits of the broadcast algorithm, there is often a high transmission delay when this application layer message is propagated to all (or most) of the blockchain nodes in the blockchain network, which can be simply expressed as: transmission delay = number of hops of a blockchain node × average transmission delay between each hop.
The transmission of the application layer message may be initiated by one of the plurality of blockchain nodes, which transmits the application layer message to the next blockchain node, and the next blockchain node may continue to transmit the application layer message to the next blockchain node, and so on, until the next blockchain node is a transmission break point or a transmission end point. In a specific example, as shown in FIG. 1, the first blockchain node 910 initiates the broadcast of an application layer message, where the first upper module 915 of the blockchain system may obtain corresponding data from, for example, a data layer module on the blockchain or other database under the blockchain, etc., and prepare the application layer message to be broadcast based on the data, including but not limited to, a blockmessage, a consensus message, etc. The first upper layer module 915 may then transmit the prepared application layer message to the first network module 914 of the blockchain system in the first blockchain node 910. The first network module 914 may communicate with the network layer of the first blockchain node 910 (including the first buffer 913 and the first network card 911 shown in fig. 1, etc.), package application layer messages to be transmitted into one or more message data (typically, each message data has a size smaller than the size of the application layer message for convenient transmission) under the influence of the network layer of the first blockchain node 910 and the first kernel 912 (which is the operating system core of the first blockchain node 910), and transmit the application layer messages serially to the second network card 921 in the second blockchain node 920 over the network via the first network card 911. In the second blockchain node 920, one or more message data received by the second network card 921 is uploaded into the second buffer 923 under the action of the second kernel 922. The second network module 924 of the blockchain network in the second blockchain node 920 may receive the message data from the second buffer 923 and combine the message data into a complete application layer message after receiving all of the message data corresponding to at least one application layer message. The second network module 924 may then upload the application layer message to a second upper module 925 of the blockchain system, and the second upper module 925 may perform authentication, encryption, decryption, etc. on the application layer message. When the application layer message is validated by the second upper layer module 925, it indicates that the application layer message is legitimate, which can be continued to be transmitted to the third blockchain node 930. Similar to the process in the first blockchain node 910, the verified application layer message may be serially transmitted by the second network card 921 to the third network card 931 in the third blockchain node 930 through network transmission through the corresponding processes of the second network module 924, the second buffer 923, the second kernel 922, and the second network card 921 in sequence. In the third blockchain node 930, one or more pieces of message data may be obtained in a similar manner in the second blockchain node 920, the message data combined to generate a complete application layer message, and the combined application layer message may be authenticated, encrypted, decrypted, etc. by a third upper module 935 of the blockchain system in the third blockchain node 930. When the third blockchain node 930 is a transmission interruption point or a transmission end point, the application layer message may not be transmitted to the next blockchain node; and when the third blockchain node 930 is not a transmission break point or transmission end point, the application layer message may continue to be transmitted to the next blockchain point in a similar manner.
Based on the above, in a blockchain network, the transmission delay between each hop can be expressed as follows: transmission delay between each hop = transmit node blockchain system processing delay + transmit node buffer delay + transmit node to receive node transmission delay + receive node buffer delay + receive node blockchain system processing delay. The processing delay of the block chain system of the sending node specifically comprises the delay of a network layer in a block chain node sending the application layer message for obtaining message data from the block chain system, including the time required by an upper module of the block chain system for preparing the application layer message and the time required by the network module for correspondingly processing the application layer message and transmitting the application layer message to the network layer; the sending node buffer delay includes a time when one or more message data associated with the application layer message transit in the buffer, especially when there are already multiple message data associated with multiple application layer messages in the buffer, it is generally required to wait for one or more message data corresponding to a previous application layer message to be sent in series, before the sending of one or more message data corresponding to a current application layer message is completed, which may result in a longer sending node buffer delay; the transmission delay from the transmitting node to the receiving node refers to the time required for transmitting message data from the network card of the blockchain node transmitting the application layer message to the network card of the blockchain node receiving the application layer message via the network; the buffer time delay of the receiving node refers to the time required for transferring the message data in the buffer of the blockchain node receiving the application layer message; and the receiving node blockchain system processing delay refers to the time required for processing, such as combining one or more pieces of message data from the buffer to generate a complete application layer message and validating the application layer message, in the blockchain node receiving the application layer message.
It can be seen that in the case of broadcasting application layer messages in a blockchain network, the transmission delay is likely to be significantly amplified due to the existence of multiple hops, which ultimately results in lower efficiency of message broadcasting in the blockchain network, and thus may adversely affect upper layer traffic in the blockchain system.
To solve the above problems, one or more embodiments of the present disclosure propose a message broadcasting method for a blockchain network, in which a transparent routing design scheme is adopted to optimize the broadcasting process of application layer messages, thereby reducing transmission delay in the blockchain network. As shown in fig. 1, the blockchain network may include at least a first blockchain node 910, a second blockchain node 920, and a third blockchain node 930. In some embodiments, the blockchain network may have a tree topology, wherein the second blockchain node 920 may be a neighbor node of the first blockchain node 910 and the third blockchain node 930 may be a neighbor node of the second blockchain node 920. As shown in fig. 4, the message broadcasting method may include:
in step S100, the second blockchain node 920 receives message data from the first blockchain node 910.
Wherein the message data may be generated by the first blockchain node 910 from an application layer message to be transmitted. Typically, the size of a complete application layer message may be 1-2 MB or more, while the size of each message data generated from the application layer message may be, for example, 64kB for ease of transmission. In each blockchain node, the message data may exist in the form of message stream data, message frame data, or message packet data, etc. In some embodiments, as shown in fig. 2 and 3, the first blockchain node 910 may transfer the message data to the second network card 921 in the second blockchain node 920 through a wired or wireless network transmission or the like using the first network card 911 therein.
Further, as shown in fig. 4, the message broadcasting method may further include:
in step S300, each time a message data is received by the second blockchain node 920, a message data is copied and forwarded to the third blockchain node 930.
Specifically, the second blockchain node 920 may immediately replicate and forward a piece of message data to the next blockchain node, namely the third blockchain node 930, upon receipt of the message data, without waiting to receive all of the message data corresponding to the complete application layer message, as described above with respect to fig. 1, and upon generation and successful verification of the application layer message from the message data, forward to the third blockchain node 930. This is because in blockchain networks, particularly in blockchain systems in certain specific scenarios, such as private chain, alliance chain systems, each blocklink point typically has a strong trust basis, i.e., the blocklink point is typically trusted without disfiguring or tampering with the data. Accordingly, in the broadcasting process of the application layer message, the verification of the application layer message by each block link point can be successfully passed basically, so that in the block chain node, the copying and forwarding of the message data can be immediately performed after each message data is received, one part of the message data can continue to flow in the block link point to participate in generating the application layer message in the subsequent steps, further the operations of verification of the application layer message and the like are realized, and the other part of the message data can be simultaneously or parallelly forwarded to the next block chain node, so that the average transmission delay between each hop is reduced, and the transmission efficiency of the message broadcasting is improved. Of course, it will be appreciated that even if a blockchain link point is bad, other methods and means may be employed in the blockchain system to locate and penalize the bad node.
In one or more embodiments of the present description, the copying and forwarding of a message data may be performed upon receipt of the message data in a variety of ways. In an exemplary embodiment, step S300 may include:
whenever the second network card 921 of the second blockchain node 920 receives a message data from the first network card 911 of the first blockchain node 910, the second blockchain node 920 copies a message data and transmits the message data to the third network card 931 of the third blockchain node 930.
As shown in fig. 2, the processing involved in the dashed box may be performed simultaneously or in parallel with the forwarding of the message data from the second network card 921 to the third network card 931. That is, forwarding of message data (e.g., in the form of ethernet frames) may be sunk to the level of the network card in a kernel bypass manner without passing through the kernel, buffers, etc. in the blockchain node, reducing the average transmission delay between each hop through such transparent forwarding. In some embodiments, replication and forwarding of message data may also be implemented using, for example, switches, bridges, etc.
In another exemplary embodiment, as shown in fig. 5, step S300 may include:
Step S331, whenever the second network card 921 of the second blockchain node 920 receives a message data from the first network card 911 of the first blockchain node 910, the second kernel 922 of the second blockchain node 920 receives a message data from the second network card 921;
step S333, the second kernel 922 converts a message data into a message data packet, and stores the message data packet in the second buffer 923 of the second blockchain node 920; and
in step S335, the second blockchain node 920 copies a message packet in the second buffer 923 and sends a message packet to the third blockchain node 930.
As shown in fig. 3, the processing involved in the dashed box may occur simultaneously or in parallel with the transmission of the message data into the third blockchain node 930 through the relevant processing of the second network card 921, the second kernel 922, and the second buffer 923. That is, in the present embodiment, message data (e.g., in the form of a TCP stream) may be replicated and forwarded at the buffer level without waiting for the results of the higher layer processing of the message data by the second network module 924 and the second upper layer module 925 of the blockchain system to reduce the average transmission delay between each hop. Message data transmitted to the third blockchain node 930 through the second network card 921 of the second blockchain node 920 may be received by the third network card 931 in the third blockchain node 930, and processing by the third kernel 932 in the third blockchain node 930 is stored in the third buffer 933 of the third blockchain node 930 to be further processed.
It will be appreciated that in other embodiments, message data may also be replicated and forwarded at other levels, e.g., the data link layer, the network layer, etc., without waiting for the processing results of the corresponding modules of the blockchain system in the blockchain node to be of a higher layer of message data to reduce the average transmission delay between each hop.
In some embodiments, the second blockchain node 920 may communicate with the first and third blockchain nodes 910 and 930 based on transmission control protocol/internet protocol, TCP/IP. Accordingly, the first buffer 913, the second buffer 923, and the third buffer 933 may be socket buffers, and the message data may be a socket byte stream.
Further, as shown in fig. 4, the message broadcasting method may further include:
in step S500, after the second blockchain node 920 receives all the message data corresponding to the complete application layer message, the application layer message is generated according to all the message data.
Wherein the application layer message may include at least one of a block message and a consensus message, the block message may characterize a block to be added to the blockchain, the block may be a set describing a series of transaction information, and the consensus message may characterize consensus information of the blockchain node. In the second blockchain node 920, all message data corresponding to the complete application layer message may be received by the second network module 924 of the blockchain system and the application layer message generated from the message data.
From the above description, it is apparent that at least one of replication and forwarding of message data may be performed in parallel with generation of application layer messages in a blockchain node. That is, in the broadcasting process of the application layer message, in each blockchain node, the message data can be forwarded without waiting for the completion of the generation of the application layer message, but the message data can be duplicated, one of the two duplicated message data is used for continuing the further processing of the message data in the blockchain node, and the other message data is forwarded to the next blockchain node simultaneously or in parallel, so as to reduce the broadcasting transmission delay of the message data.
In one or more embodiments of the present disclosure, as shown in fig. 6, the message broadcasting method may further include:
in step S700, the second blockchain node 920 performs a preset process on the application layer message.
The preset processing of the application layer message may include verification, encryption and/or decryption of the application layer message, and the like. Verifying the application layer message may help determine whether the application layer message has been tampered with maliciously, etc., to ensure that the data and operations corresponding to the application layer message are reliable. The security of the application layer message can be better ensured by encrypting the application layer message. And, a blockchain node in the same blockchain network may decrypt the application layer messages it receives based on a predetermined manner to obtain the required information therefrom. It will be appreciated that other preset processing of the application layer messages may also be performed based on the blockchain system (e.g., according to a smart contract in the blockchain system, etc.), without limitation.
Specifically, step S700 may include:
step S711, the second upper layer module 925 of the blockchain system of the second blockchain node 920 obtains the application layer message from the second network module 924 of the blockchain system of the second blockchain node 920; and
in step S713, the second upper module 925 performs a preset process on the application layer message.
Wherein upper modules of the blockchain system may include, for example, at least one of a consensus layer module, an application layer module, an incentive layer module, and a contract layer module. The consensus layer module can comprise a consensus algorithm and a consensus mechanism, and is responsible for effective identification and authentication of the point-to-point mode, so that highly dispersed blockchain nodes efficiently achieve consensus on the validity of the blockdata in the decentralised blockchain network. The application layer module can realize various application scenes, and can contain various application scenes and cases. The incentive layer module can comprise an issuing system, an allocation system and the like of economic incentives to provide certain incentive measures to encourage the nodes to participate in the security verification work of the blockchain. The contract layer module may include various scripts, code, algorithmic mechanisms, and smart contracts, which are the basis for blockchain programmability.
It will be appreciated that at least one of copying and forwarding of message data may also be performed in parallel with the pre-set processing of the application layer message. That is, in the process of broadcasting the application layer message, in each blockchain node, forwarding of message data can be directly performed without waiting for the result of the preset processing of the application layer message. One of the two message data obtained by copying is used for continuing to process the message data and the application layer message in the block chain node, and the other message data is simultaneously or parallelly forwarded to the next block chain node, so that the broadcast transmission delay of the message data is reduced.
In one or more embodiments of the present disclosure, transparent routing techniques are used to parallelize the processes of receiving and verifying the complete application layer message with the process of transmitting the message data for forming the application layer message, whenever a block link node receives a message data from its previous block chain node, the current block chain node can immediately copy the message data and forward the message data to its next block chain node or nodes, without waiting for the current block chain node to receive the complete block chain application layer message, and while forwarding the message data to the next block chain node or nodes, the current block chain node can wait in parallel for receiving other message data associated with the complete application layer message, assemble and combine the message data to generate a final complete application layer message, and pass the application layer message to an upper layer module in the block chain system for further processing, thereby eliminating the time spent waiting for receiving all message data corresponding to the complete application layer message in each of the broadcast layer message, forming a combined layer, using the application layer, and forming a layer, reducing the number of time delay and forwarding the application layer, reducing the number of time delay and the transmission layer to be used by the nodes, reducing the number of time delay and the number of forwarding the application layer, and reducing the time delay of the transmission layer and the like. Especially when the blockchain network contains more blockchain nodes and the broadcasting depth is deeper, the transmission mode can obviously reduce the overall transmission delay, for example, the transmission delay can be reduced by more than 30 percent.
In addition, one or more embodiments of the present specification also propose a blockchain node that may be, for example, the first blockchain node 910, the second blockchain node 920, or the third blockchain node 930 shown in fig. 1-3. Taking the second blockchain node 920 as an example, it may include a communication module and a network module of the blockchain system (second network module 924). Wherein the communication module may be configured to: receiving message data from a first blockchain node different from the blockchain node; and each time a block link point receives a message data, copying the message data and forwarding the message data to a third block chain node different from the block chain node and the first block chain node. The network module may be configured to generate an application layer message from all message data after receiving all message data corresponding to a complete application layer message at a block link point.
In some embodiments, the communication module may include a network card (e.g., second network card 921) and a buffer (e.g., second buffer 923). The network card may be configured to receive message data from a first blockchain node different from the blockchain node, and the network card may be further configured to send one message data to a third blockchain node different from the blockchain node and the first blockchain node. Further, the buffer may be configured to store message data packets resulting from the message data conversion, the message data packets in the buffer configured to be sent to a third blockchain node different from the blockchain node and the first blockchain node.
In some embodiments, the blockchain node may also include an upper module of the blockchain system (e.g., the second upper module 925) that may be configured to obtain the application layer message from the network module and perform a preset process on the application layer message. Specifically, the upper layer module may include at least one of a consensus layer module, an application layer module, an incentive layer module, and a contract layer module.
As described above, at least one of copying and forwarding of message data and at least one of generation and preset processing of an application layer message may be performed in parallel. Wherein the preset process may include at least one of authentication, encryption, and decryption.
Further, one or more embodiments of the present specification also provide a blockchain system that may include the blockchain nodes as described above. Wherein the blockchain network of the blockchain system may have a tree topology.
In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable Gate Array, FPGA)) is an integrated circuit whose logic function is determined by the user programming the device. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented by using "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before the compiling is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but not just one of the hdds, but a plurality of kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), lava, lola, myHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application specific integrated circuits (Application Specific Integrated Circuit, ASIC), programmable logic controllers, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.
The system, apparatus, module or unit set forth in the above embodiments may be implemented in particular by a computer chip or entity, or by a product having a certain function. One typical implementation device is a server system. Of course, the application does not exclude that as future computer technology advances, the computer implementing the functions of the above-described embodiments may be, for example, a personal computer, a laptop computer, a car-mounted human-computer interaction device, a cellular telephone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
Although one or more embodiments of the present description provide method operational steps as described in the embodiments or flowcharts, more or fewer operational steps may be included based on conventional or non-inventive means. The order of steps recited in the embodiments is merely one way of performing the order of steps and does not represent a unique order of execution.
