At present, the block chain technology is evolved from 1.0 version which takes bitcoin as a main part to 2.0 version of an intelligent contract, and becomes a new technology which has great potential to be applied to various industries.

For example, a Bitfinex transaction platform constructed based on the blockchain technology is stolen by 12 ten thousand of megabits in 2016, but the transaction platform cannot trace the source and the hacker due to the defects of the blockchain technology, and the loss can only be leveled by the user.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
It should be noted that, in the embodiments of the present invention, "of", "corresponding" and "corresponding" may be sometimes used in combination, and it should be noted that, when the difference is not emphasized, the intended meaning is consistent.
For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used for distinguishing the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like are not limited in number or execution order.
The block chain structure in the existing block chain technology has the characteristics of strong robustness and disclosure transparency due to the characteristics of openness, consensus, decentralization and distrust, but because transaction information and property information of all users in the block chain system are stored in each server node in the original block chain system, and because data change in the block chain system cannot be tracked in a secret way when the user information of the block chain in the same time zone can not be modified, once the whole system of the block chain is subjected to network attack and network lasso, the block chain system cannot guarantee property security of the users.
In view of the above problem, referring to fig. 1, an embodiment of the present invention provides a method for detecting data anomaly of a blockchain service in a blockchain system, including:
101. the block chain core server obtains at least one block chain service data through a core SDN (software defined Network) router connected with the block chain core server.
The at least one block chain service data is generated by at least one block chain service server and is sent to a service SDN router corresponding to address data in the at least one block chain service data and a core SDN router connected with the block chain core server through service SDN routers connected with the at least one block chain service server; in practice, since there is more than one blockchain core server in the blockchain system, the blockchain service servers of the whole system are generally divided into several parts to be managed by different blockchain core servers, and of course, all the blockchain service servers can be managed by one blockchain core server, which is not limited herein.
In addition, because it is necessary to distinguish the network of the blockchain system from the public network, when the service SDN router sends the blockchain service data generated by the blockchain service server, a label that can only be identified by the service SDN router or the core router in the blockchain system is added to the blockchain service data, so that the following options are available: before sending the blockchain service data, the SDN router connected to any blockchain service server further includes: a service SDN router connected with any block chain service server sets a preset label for block chain service data so that a service SDN router or a core SDN router receiving the block chain service data identifies and acquires the block chain service data;
it should be noted that, data transmission among the core SDN router, the service SDN router, and the control SDN router is performed, as long as the transmitted data is usage data belonging to a blockchain system, the SDN router that correspondingly sends the data sets a preset tag for the sent data, and here, only one of the cases is schematically selected for description;
specifically, the SDN router encapsulates forwarding packets in the blockchain system to some extent by using a tunneling technique (e.g., MPLS (Multi-Protocol Label Switching), Vxlan (virtual extensible LAN, virtual extensible local area network, or other techniques)) in a normal data forwarding function technique of a three-layer forwarding device in a communication network, so that SDN routers in the whole blockchain system can recognize each other to form a private network dedicated to a blockchain service server connected to each SDN router.
102. And the block chain core server judges whether the block chain service server has data abnormality or not according to all the acquired block chain service data and a preset algorithm.
In practice, the block chain service server with data abnormality is judged according to data through a preset algorithm, and the data can be displayed to a specific professional manager for judgment; the block chain core server not only needs to judge which block chain service servers have data abnormality, but also determines which data abnormality occurs; in addition, in a special case, when the blockchain core server itself also performs the service activity of the blockchain service server, the blockchain core server itself may also have data abnormality, and at this time, the blockchain core server is also a special blockchain service server, and at this time, the data abnormality of the blockchain core server is also determined by itself, and the processing procedure is the same as that of the normal blockchain service server.
103. When the blockchain core server determines that the target blockchain service server has data abnormality, a processing instruction corresponding to the data abnormality is sent to the SDN controller through a core SDN router connected with the blockchain core server and a control SDN router connected with the SDN controller.
The target block chain service server is any one of the at least one block chain service server;
in practice, the processing instruction carries a preliminary processing policy (for example, temporarily isolating the blockchain service server and adjusting the available network bandwidth of the blockchain service server) that is determined by the blockchain core server according to the specific data exception category of the blockchain service server with data exception.
104. And after receiving the processing instruction, the SDN controller generates router configuration parameters corresponding to the processing instruction, and sends the router configuration parameters to a service SDN router connected with a target block chain service server through a control SDN router connected with the SDN controller.
Illustratively, the data exception of the target blockchain service server at least comprises: the target block chain service server is attacked, so that the block chain service function and the preset of the target block chain service server are inconsistent, the target block chain service server issues illegal information, and the number of block chain service data generated by the target block chain service server exceeds a preset standard; the processing instruction is at least one of the following: a first processing instruction, a second processing instruction, and a third processing instruction; the target block chain service server is attacked, so that the block chain service function of the target block chain service server is inconsistent with the preset first processing instruction, the target block chain service server issues illegal information corresponding to the second processing instruction, and the number of the block chain service data of the target block chain service server exceeds the preset standard corresponding to the third processing instruction;
illustratively, the step 104 shown in fig. 2 specifically includes:
1041. and when the SDN controller receives the first processing instruction, generating router firewall configuration parameters, and sending the router firewall configuration parameters to a service SDN router connected with a target block chain service server through a control SDN router connected with the SDN controller.
1042. And when the SDN controller receives the second processing instruction, generating a router port configuration parameter, and sending the router port configuration parameter to a service SDN router connected with the target block chain service server through a control SDN router connected with the SDN controller.
1043. And when the SDN controller receives the third processing instruction, generating a router bandwidth configuration parameter, and sending the router bandwidth configuration parameter to a service SDN router connected with the target block chain service server through a control SDN router connected with the SDN controller.
105. And the service SDN router connected with the target block chain service server updates the self configuration according to the router configuration parameters.
Specifically, referring to fig. 2, the step 105 specifically includes:
1051. and the service SDN router connected with the target block chain service server updates the firewall configuration of the service SDN router according to the firewall configuration parameters of the router.
1052. And the service SDN router connected with the target block chain service server closes the port for issuing illegal information according to the configuration parameters of the router port.
1053. And the service SDN router connected with the target block chain service server adjusts the available bandwidth for data transmission according to the router bandwidth configuration parameter.
Since in practice, a new user will join the blockchain system at any time, and thus a new blockchain service server will be generated, optionally, referring to fig. 3, when a new blockchain service server joins the blockchain system where the SDN controller is located, the method further includes:
and S1, the SDN controller receives a docking instruction sent by the new blockchain service server through the service SDN router connected with the SDN controller through the SDN controller to complete docking, and the docking instruction carries address data of the new blockchain service server.
Specifically, the address data of the new blockchain service server should include the address of the service SDN router connected thereto, and is finally forwarded to the new blockchain service server through the service SDN router.
And S2, the blockchain core server sends the blockchain service data and the address data of all blockchain service servers in the blockchain system stored by the blockchain core server to the new blockchain service server through the core SDN router connected with the blockchain core server and the service SDN router connected with the new blockchain service server.
Specifically, since the blockchain system requires that each blockchain service server has all the service information generated by the blockchain system and the addresses of other blockchain service servers that can be contacted by service, S2 exists.
And S3, after the service SDN router connected with the new blockchain service server is in butt joint with the SDN controller, the blockchain core server acquires blockchain service data generated by the new blockchain service server and sent by the service SDN router connected with the blockchain core server through the core SDN router connected with the blockchain core server.
The block chain core server obtains at least one block chain service data through a core SDN router connected with the block chain core server, wherein the at least one block chain service data is generated by the at least one block chain service server and is sent to an SDN router corresponding to address data in the at least one block chain service data and the core SDN router connected with the block chain core server through service SDN routers respectively connected with the at least one block chain service server; the block chain core server judges whether a block chain service server in at least one block chain service server has data abnormality according to all the acquired block chain service data and a preset algorithm; when the block chain core server determines that the target block chain service server has data abnormality, sending a processing instruction corresponding to the data abnormality to an SDN controller through a core SDN router connected with the block chain core server and a control SDN router connected with an SDN controller; the target block chain service server is any one of the at least one block chain service server; after receiving the processing instruction, the SDN controller generates router configuration parameters corresponding to the processing instruction, and sends the router configuration parameters to a service SDN router connected with a target block chain service server through a control SDN router connected with the SDN controller; and the service SDN router connected with the target block chain service server updates the self configuration according to the router configuration parameters.
