The block chain is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence, and is a distributed account book which is guaranteed in a cryptographic mode and cannot be tampered and forged. Broadly speaking, the blockchain technique is a completely new distributed infrastructure and computing paradigm that utilizes blockchain data structures to verify and store data, utilizes distributed node consensus algorithms to generate and update data, cryptographically secure data transmission and access, and utilizes intelligent contracts composed of automated script code to program and manipulate data.
The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in the blockchain system. Is essentially a decentralized database and simultaneously serves as the bottom layer technology of the bitcoin. The block chain is a series of data blocks which are associated by using a cryptographic method, and each data block contains information of one bitcoin network transaction, so that the validity (anti-counterfeiting) of the information is verified and the next block is generated. Blockchain design is a protective measure, such as (applied to) highly fault-tolerant distributed computing systems. Block chains enable mixed consistency. This makes the blockchain suitable for recording events, titles, medical records and other activities requiring the inclusion of data, identification management, transaction flow management and provenance management. The blockchain has huge potential for financial off-media and has huge influence on leading global trade.
The node of the current block chain mainly has the functions of the following aspects: P2P network functions, broadcast message transmission and reception, accounting rights calculation, signing and encryption/decryption, ledger storage, etc. These functions are present for transactions in the blockchain network.
In the prior art, there are two ways to issue transaction information in a blockchain network: the first mode is that each node broadcasts the related transaction information to the whole block chain network in a broadcasting mode, and then each node receives all transaction data in the whole block chain network; the second mode is that each node issues the transaction information related to itself to the central node, and the central node performs uniform transaction issuing at a fixed period of time.
For the first method, if the transactions in the blockchain network are frequent, the transmission pressure of the blockchain network is large, and for a single node in the blockchain network, the transaction information of the entire blockchain network needs to be stored, so that the single node needs to have a large storage space. With the second approach, once the central node fails, the entire blockchain network fails. To solve the problem, the present embodiment provides a method for processing blockchain transaction information, and the method for processing blockchain transaction information is described below with reference to specific embodiments.
The block chain transaction information processing method provided by the invention can be applied to the communication system shown in fig. 1. As shown in fig. 1, the communication system includes: the blockchain network 10 and the blockchain nodes 11 to blockchain link points 17 are only schematically illustrated here, and the specific number of blockchain nodes is not limited. The blockchain node may specifically be a smartphone, a tablet, a laptop, etc., and combinations thereof.
The invention provides a block chain transaction information processing method, which aims to solve the technical problems in the prior art.
The following describes the technical solutions of the present invention and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a method for processing blockchain transaction information according to an embodiment of the present invention. The embodiment of the invention provides a block chain transaction information processing method aiming at the technical problems in the prior art, and the method comprises the following specific steps:
at step 201, a block link node divides transaction information associated therewith into a plurality of segments.
As shown in fig. 1, any one of the blockchain link points 11-17 may perform network transaction with other blockchain nodes, for example, the blockchain node 14 may perform network transaction with other blockchain nodes, for example, the blockchain node 11 through the blockchain network 10, during the transaction, the blockchain link point 14 and/or the blockchain node 11 may generate transaction information, and the blockchain link point 14 and/or the blockchain node 11 needs to issue the transaction information into the blockchain network 10, in this embodiment, the blockchain node 14 and/or the blockchain node 11 does not issue the transaction information itself into the blockchain network 10. Taking the blockchain node 14 as an example, when the blockchain node 14 needs to issue the transaction information into the blockchain network 10, the blockchain node 14 first divides the transaction information that needs to be issued into the blockchain network 10 into a plurality of segments, for example, n segments.
Optionally, the number of the segments is determined according to the size of the transaction information and the total number of the adjacent nodes of the blockchain node. That is, n is determined by the blockchain node 14 according to the size of the transaction information and the total number of neighboring nodes of the blockchain node 14. As shown in fig. 1, it is assumed that the neighbors of blockchain node 14 may include: block chain node 12, block link point 13, block link point 15, block link point 16. That is, the number of neighboring nodes of the blockchain node 14 is 4. Specifically, the blockchain node 14 calculates the number n of segments into which the transaction information needs to be divided according to the size of the transaction information and the total number 4 of the adjacent nodes of the blockchain node 14 by using a first preset algorithm.
As shown in fig. 1, the block link point 12, the block link point 13, the block link point 15, and the block link point 16 are adjacent nodes of the block link node 14, and the block link node 14 may transmit each of the n segments to the block link node 12, the block link point 13, the block link point 15, and the block link point 16. However, malicious nodes, illegal nodes or faulty nodes may exist in the block link points 12, 13, 15, and 16, and in order to avoid malicious or illegal nodes from modifying the contents of the fragmented segments maliciously or that the faulty nodes cannot process the fragmented segments normally, the block link node 14 may select a block link node with high reliability from the block link points 12, 13, 15, and 16, and send each of the n segments to the block link node with high reliability instead of sending the n segments to all neighboring nodes.
The embodiment does not limit the specific method selected. It is assumed that the block chain node 14 with higher reliability selected from the block chain link point 12, the block chain link point 13, the block chain link point 15, and the block chain link point 16 is the block chain link point 12 and the block chain link point 13, that is, the number of at least one target adjacent node selected by the block chain node 14 is 2. And sends each of the n segments to the block chain node 12 and the block chain node 13.
Optionally, the number of the at least one target neighboring node is determined according to the total number of neighboring nodes of the block chain node and the number of the segments. Assuming that the number of the at least one target adjacent node selected by the blockchain node 14 is M, and the total number of the adjacent nodes of the blockchain node 14 is W, the blockchain node 14 may determine the number M of the at least one target adjacent node by using a second preset algorithm according to the total number W of the adjacent nodes of the blockchain node 14 and the number n of the segments into which the transaction information needs to be divided. That is, the block-link point 14 selects M target neighboring nodes from all W block-link points that are neighboring thereto. And sends each of the n segments to the M target neighbor nodes instead of all W blockchain nodes.
As shown in fig. 1, assuming that the blockchain node 14 and the blockchain node 11 perform network transaction through the blockchain network 10, during the transaction, the blockchain link point 14 and/or the blockchain link point 11 may generate transaction information, it can be understood that the transaction parties of the transaction information are the blockchain link point 14 and the blockchain link point 11, and the transaction party information may be identification information of the blockchain node 14 and identification information of the blockchain link point 11.
In the present embodiment, after the blockchain node 14 selects M target neighboring nodes from all W blockchain nodes adjacent to the blockchain node, the blockchain node 14 issues transaction party information of the transaction information, i.e., identification information of the blockchain node 14 and identification information of the blockchain node 11, and address information of each neighboring node in at least one target neighboring node of the blockchain node 14, i.e., address information of the blockchain node 12 and address information of the blockchain node 13, into the blockchain network 10. Specifically, the block chain node 14 broadcasts the identification information of the block chain node 14 and the identification information of the block chain link point 11, and the address information of the block chain node 12 and the address information of the block chain link point 13 into the block chain network 10. Other blockchain nodes in the blockchain network 10 will receive the broadcast message sent by the blockchain node 14, where the broadcast message includes identification information of the blockchain node 14 and identification information of the blockchain node 11, and address information of the blockchain node 12 and address information of the blockchain node 13. The broadcast message means that: the segment of the transaction information generated when the blockchain node 14 and the blockchain node 11 perform the transaction is stored in the blockchain link point 12 and the blockchain link point 13, and other blockchain nodes in the blockchain network 10 may obtain the segment of the transaction information generated when the blockchain node 14 and the blockchain node 11 perform the transaction from the blockchain link point 12 and the blockchain link point 13 according to the address information of the blockchain node 12 and the address information of the blockchain link point 13.
Other block chain nodes in the block chain network store transaction party information related to the transaction information and address information of each adjacent node in at least one target adjacent node.
After the blockchain node 14 broadcasts the identification information of the blockchain node 14 and the identification information of the blockchain link point 11, and the address information of the blockchain node 12 and the address information of the blockchain link point 13 to the blockchain network 10, the other blockchain nodes in the blockchain network 10 perform the preemption of the accounting right in a manner of preempting the accounting right in the prior art, the blockchain link point which preempts the accounting right stores the message broadcast by the blockchain node 14 in the block, and all the blockchain links in the blockchain network 10 need to store all the blocks in the blockchain network 10 locally, that is, in the prior art, all the blocks in the blockchain network 10 store the content of the transaction information itself, in the embodiment, all the blocks in the blockchain network 10 store the transaction party information related to the transaction information and the address information of the blockchain link point storing the segment of the transaction information, optionally, the address information of the block link point of the segment in which the transaction information is stored may be address index table information.
For example, other blockchain nodes in the blockchain network 10 store locally the identification information of the blockchain node 14 and the identification information of the blockchain node 11 broadcast by the blockchain node 14, and the address information of the blockchain node 12 and the address information of the blockchain node 13.
It can be understood that, in this embodiment, the blockchain node 14 may perform network transaction with not only the blockchain node 11 but also other blockchain nodes, and when the blockchain node 14 performs network transaction with other blockchain nodes, the blockchain node 14 issues transaction party information and address information of the blockchain node storing the segment of the transaction information to the blockchain network. In addition, other blockchain nodes besides the blockchain node 14 may also issue transaction party information of network transactions related thereto and address information of the blockchain nodes storing the segments of the transaction information into the blockchain network.
In the embodiment of the invention, the transaction party information related to the transaction information and the address information of the block chain link point of the segment storing the transaction information are issued to the block chain network instead of issuing the content of the transaction information to the block chain network, so that the transmission pressure of the block chain network can be reduced, the storage space of a single node can be reduced for the single node in the block chain network, in addition, each of a plurality of fragments of the same transaction information is stored on a plurality of block chain nodes, the fault caused by the malicious modification of the fragment content by a certain block chain link point is avoided, and the safety of the block chain network is improved.
Fig. 3 is a flowchart of a method for processing blockchain transaction information according to another embodiment of the invention. On the basis of the foregoing embodiment, the method for processing blockchain transaction information provided by this embodiment includes the following steps:
in step 301, a block link point divides transaction information associated therewith into a plurality of segments.
The implementation principles and manners of steps 301 to 303 are consistent with those of steps 201 to 203, and are not described herein again.
For example, the blockchain node 14 needs to perform a transaction with the blockchain link point 17 in the blockchain network 10, for example, the blockchain link point 17 owns a product that the blockchain node 14 wants to purchase, the blockchain node 14 needs to send a transaction request to the blockchain link point 17, the transaction request includes information of the amount of money of the product, and assuming that the price of the product that the blockchain node 14 wants to purchase is 10 yuan, the transaction request may specifically be: the blockchain node 14 pays 10 dollars to the blockchain link point 17. After receiving the transaction request sent by the blockchain node 14, the blockchain node 17 confirms whether the blockchain node 14 has the capability of paying 10 dollars. Optionally, the block link point 17 queries the block information in the locally stored block link network 10, and obtains address index table information of all transactions related to the block link point 14 from the block information, where the address index table information may include a plurality of address information, the plurality of address information may be address information of a plurality of block link nodes, and the plurality of block link points may be block link points storing segments of all transaction information related to the block link point 14. Assuming that all pieces of transaction information related to the block link point 14 are stored at the block link point 12 and the block link point 13, the address index table information includes address information of the block link node 12 and address information of the block link point 13.
In other embodiments, all the segments of the transaction information related to the block link point 14 may not be limited to be stored in the block link point 12 and the block link point 13, but may also be stored in the block link point 12, the block link point 13, the block link point 15, and the block link point 16, in which case, the address index table information includes address information of the block link node 12, address information of the block link point 13, address information of the block link point 15, and address information of the block link point 16.
After the block link point 17 queries and acquires the address index table information of all transactions related to the block link point 14, the neighboring nodes related to the block chain node 14, such as the block chain node 12 and the block link point 13, are determined according to the address information in the address index table information. Further, the block link point 17 sends a request message for requesting to acquire the segments of the transaction information of all transactions related to the block link point 14 to the block link point 12 and the block link point 13, respectively. After the block link point 12 and the block link point 13 receive the request message, the block link node 12 and the block link point 13 send the locally stored segments of the transaction information of all transactions related to the block link node 14 to the block link node 17, and after the block link point 17 receives the segments of the transaction information of all transactions related to the block link point 14 returned by the block link node 12 and the block link point 13, it is determined which segments belong to the same transaction information, and the segments belonging to the same transaction information are combined to form the transaction information of one transaction related to the block link point 14. In this way, the transaction information of the multiple transactions related to the blockchain node 14 can be combined, and further, the blockchain node 17 calculates the remaining amount of the blockchain node 14 according to the transaction information of the multiple transactions related to the blockchain node 14. If the remaining amount of the blockchain node 14 is greater than 10 yuan, the blockchain link point 17 confirms that the transaction is performed with the blockchain node 14, and if the remaining amount of the blockchain link point 14 is less than 10 yuan, the blockchain link point 17 stops performing the transaction with the blockchain node 14.
It is understood that any one of the block link points 11-17 may perform network transaction with other block chain nodes, and when any one of the block chain nodes 11-17 performs network transaction with another block chain node, it may be determined whether the party requesting the transaction has the ability to continue the transaction according to the method similar to the method provided by the present embodiment in which the block link point 17 determines the remaining amount of the block chain node 14.
In the embodiment of the invention, the transaction party information related to the transaction information and the address information of the block chain link point of the segment storing the transaction information are issued to the block chain network instead of issuing the content of the transaction information to the block chain network, so that the transmission pressure of the block chain network can be reduced, the storage space of a single node can be reduced for the single node in the block chain network, in addition, each of a plurality of fragments of the same transaction information is stored on a plurality of block chain nodes, the fault caused by the malicious modification of the fragment content by a certain block chain link point is avoided, and the safety of the block chain network is improved.
Fig. 4 is a structural diagram of a blockchain node according to an embodiment of the present invention. As shown in fig. 4, the blockchain link node 40 may execute the processing procedure provided in the embodiment of the blockchain transaction information processing method, and includes: the system comprises a slicing module 41 and a sending module 42, wherein the slicing module 41 is used for dividing transaction information related to block link points into a plurality of segments; a sending module 42 configured to send each of the plurality of segments to at least one target neighboring node of the blockchain node; and issuing transaction party information related to the transaction information and address information of each of the at least one target neighbor node into a blockchain network.
Optionally, the number of the segments is determined according to the size of the transaction information and the total number of the adjacent nodes of the blockchain node.
Optionally, the number of the at least one target neighboring node is determined according to the total number of neighboring nodes of the block chain node and the number of the segments.
Optionally, other blockchain nodes in the blockchain network store transaction party information related to the transaction information and address information of each neighboring node in at least one target neighboring node.
The block link points provided by the embodiment of the present invention may be specifically used for executing the method embodiment provided by fig. 2, and specific functions are not described herein again.
In the embodiment of the invention, the transaction party information related to the transaction information and the address information of the block chain link point of the segment storing the transaction information are issued to the block chain network instead of issuing the content of the transaction information to the block chain network, so that the transmission pressure of the block chain network can be reduced, the storage space of a single node can be reduced for the single node in the block chain network, in addition, each of a plurality of fragments of the same transaction information is stored on a plurality of block chain nodes, the fault caused by the malicious modification of the fragment content by a certain block chain link point is avoided, and the safety of the block chain network is improved.
On the basis of the foregoing embodiment, the sending module 42 is further configured to: sending a transaction request to the other block chain nodes so that the other block chain nodes inquire address information of at least one target adjacent node of the block chain nodes, acquiring a segment of transaction information related to the block chain nodes from the at least one target adjacent node according to the address information of the at least one target adjacent node, and determining whether to perform transaction with the block chain nodes according to the segment of the transaction information related to the block chain nodes.
The block link points provided by the embodiment of the present invention may be specifically used for executing the method embodiment provided by fig. 3, and specific functions are not described herein again.
In the embodiment of the invention, the transaction party information related to the transaction information and the address information of the block chain link point of the segment storing the transaction information are issued to the block chain network instead of issuing the content of the transaction information to the block chain network, so that the transmission pressure of the block chain network can be reduced, the storage space of a single node can be reduced for the single node in the block chain network, in addition, each of a plurality of fragments of the same transaction information is stored on a plurality of block chain nodes, the fault caused by the malicious modification of the fragment content by a certain block chain link point is avoided, and the safety of the block chain network is improved.
