Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1A is a flowchart of a data transmission method based on a blockchain according to the first embodiment of the present invention, and fig. 1B is a network architecture diagram of a blockchain network node deployment according to the first embodiment of the present invention. Optionally, the nodes in the blockchain network are deployed in different public domains, each public domain includes at least one hierarchical sub-domain, so that the network environment can be divided into tree-like structures, each sub-domain has a domain name, and the domain name of the higher-level domain belonging to the same public domain is the prefix of the domain name of the sub-domain; the highest hierarchical domain in the public domain is the primary domain. Each sub-domain includes a bridge node and at least one consensus node is divided into a consensus node and a bridge node. As shown in fig. 1B, where the domain [ a ], the domain [ a, B ], and the domain [ a, B, a ] belong to the same common domain, the domain [ a ] is a first-level domain, and domains having different levels under the domain [ a ] such as domains [ a, a ], the domain [ a, B ], and the domain [ a, B, a ] are domains of the domain [ a ]; nodes 1-7 are consensus nodes. The bridging nodes do not participate in network consensus, only forward the data, and communicate with the bridging nodes of other domains; the consensus nodes between different domains cannot communicate directly, but only through bridging nodes.
The embodiment can be suitable for the situation of data transmission among nodes in a block chain network, and is particularly suitable for the situation of data transmission among nodes in the block chain network in a complex network environment. The method may be performed by a blockchain-based data transmission device, which may be implemented in software and/or hardware, and may be integrated in an electronic device of a bridge node in a blockchain network.
As shown in fig. 1A, the method specifically may include:
s110, responding to the data processing transaction request of the source node, and determining the target domain where the target node is located according to the address information of the target node in the data processing transaction request.
In this embodiment, the source node is a consensus node in the blockchain network that initiates the data transaction request, that is, an initiator of message consensus, and optionally, the source node may generate a consensus message according to local consensus calculation, and then construct the data transaction request according to the consensus message, the source node IP address, the source domain address, the destination node IP address, the destination domain address, and the like. The consensus message refers to message data that the source node and the target node need to perform consensus. By target node is meant the consensus node in the blockchain network that ultimately receives the consensus message.
By data transaction request is meant a request for instructing a blockchain node to process data, and optionally the data transaction request may include a consensus message, a source node address, source domain address information, a destination node address, destination domain address information, etc. Where the node address refers to the IP address of the node.
The address information of the target node is IP address information of the target node. Each bridging node is cached with node IP address and mapping information of domain.
Specifically, the local node responds to a data processing thing request initiated by the source node or a data processing thing request forwarded by other bridging nodes, further acquires IP address information of the target node from the data processing thing request, and searches a target domain where the target node is located from the mapping information of the node IP address and the domain of the local cache based on the IP address of the target node.
S120, determining whether the target domain is the same as the current domain where the local node is located.
In this embodiment, the current domain refers to the domain where the local node is located.
Specifically, the local node determines whether the target domain is the same as the current domain according to the domain name of the target domain and the domain name of the current domain where the local node is located, for example, if the domain name of the target domain is the same as the domain name of the current domain, the target domain is the same as the current domain.
And S130, if not, determining an intermediate bridging node according to the domain name of the current domain and the domain name of the target domain.
In this embodiment, the intermediate bridge node refers to a bridge node that needs to be passed when the source node and the target node perform cross-domain communication.
Optionally, if the current domain and the target domain are different, i.e. the current domain and the target domain do not belong to the same domain, i.e. the cross-domain transmission is required, the intermediate bridge node is determined according to the domain name of the current domain and the domain name of the target domain. And then S140 is performed.
Optionally, if the target domain is the same as the current domain, the data processing transaction request is transmitted to the target node. That is, if the local node (local bridge node) and the target node belong to the same network domain, the data processing transaction request is transmitted to the target node according to the Gossip protocol, so as to complete data transmission. S140 is not being performed.
S140, transmitting the data processing transaction request to the intermediate bridge node so that the intermediate bridge node transmits the data processing transaction request to the target node.
Illustratively, the local bridge node transmits a data transaction request to the intermediate bridge node; correspondingly, if the intermediate bridge node is not the target bridge node of the target domain where the target node is located, repeating the steps until the target bridge node of the target domain is determined, and then, the target bridge node transmits the data processing transaction request to the target node according to the Gossip protocol so as to complete the final data transmission.
If the intermediate bridge node is the target bridge node of the target domain where the target node is located, the intermediate bridge node, that is, the target bridge node, transmits the data processing transaction request to the target node according to the Gossip protocol so as to complete data transmission.
According to the technical scheme of the embodiment of the invention, the target domain where the target node is located is determined according to the address information of the target node in the data processing transaction request by responding to the data processing transaction request of the source node, whether the target domain is the same as the current domain where the local node is located is determined, if not, the intermediate bridging node is determined according to the domain name of the current domain and the domain name of the target domain, and the data processing transaction request is transmitted to the intermediate bridging node, so that the intermediate bridging node transmits the data processing transaction request to the target node. According to the technical scheme, the bridge node is introduced, so that the efficiency of data synchronization of the block chain nodes is improved, meanwhile, under a complex network environment, efficient and safe communication among the block chain nodes is ensured, and the dependence of a node deployment mode on physical network topology is reduced.
On the basis of the technical scheme, as an optional mode of the embodiment of the invention, the validity check can also be performed on the data processing transaction request.
For example, network security rules may be checked for data processing transaction requests, and if the check passes, the data processing transaction request is legitimate. If the verification is not passed, the data processing transaction request is not forwarded, namely discarded.
By way of example, it may also be determined whether the number of data forwarding times in the data processing transaction request meets a time threshold; if so, determining that the data processing transaction request is legal. Wherein the number of times threshold can be set by a person skilled in the art according to the actual situation. If not, the data processing transaction request is not forwarded, namely discarded.
In this embodiment, it should be noted that after the common message passes through the bridge node, the number of data forwarding times is recorded, and the number of data forwarding times is added to the data processing transaction request.
Based on the above embodiment, as an alternative manner of the embodiment of the present invention, a certain security policy may be set for a node in the blockchain network, and only the computer device in the local domain is responded to perform an operation request for the blockchain node in the local domain, where the operation request includes querying, sending a transaction, calling a contract, and so on.
It can be appreciated that by configuring security policies in nodes of the blockchain network, message awareness among the blockchain nodes of different domains can be reduced, the possibility of data storm occurrence can be reduced, and the security of the blockchain network can be protected.
Example two
Fig. 2 is a flowchart of a blockchain-based data transmission method according to a second embodiment of the present invention, and on the basis of the foregoing embodiment, an alternative implementation is provided for further optimizing "determining an intermediate bridge node according to the domain name of the current domain and the domain name of the target domain".
As shown in fig. 2, the method specifically may include:
s210, responding to a data processing transaction request of a source node, and determining a target domain where a target node is located according to address information of the target node in the data processing transaction request.
S220, determining whether the target domain is the same as the current domain where the local node is located.
If not, selecting an intermediate bridge node from the bridge nodes in the first public domain when the first public domain to which the current domain belongs and the second public domain to which the target domain belongs are the same public domain.
In this embodiment, the first public domain refers to a public domain to which the current domain belongs; the second common domain refers to a common domain to which the target domain belongs.
Optionally, in the case that the first public domain to which the current domain belongs and the second public domain to which the target domain belongs are the same public domain, selecting an intermediate bridge node from the bridge nodes in the first public domain may be determining whether the domain name of the current domain is a prefix of the domain name of the target domain; if yes, constructing a lower domain of the current domain according to the domain name of the current domain and the domain name of the target domain, and taking the bridge node in the lower domain as an intermediate bridge node. If not, the bridge node in the upper domain of the current domain is taken as an intermediate bridge node.
Illustratively, if the domain name of the current domain is a prefix of the domain name of the target domain, that is, an upper-level domain of the current domain and the target domain, a lower-level domain of the current domain is constructed according to the domain name of the current domain and the domain name of the target domain, and a bridge node of the lower-level domain is used as an intermediate bridge node.
Alternatively, constructing the lower domain of the current domain according to the domain name of the current domain and the domain name of the target domain may be that the domain name of the target domain is de-duplicated according to the domain name of the current domain to obtain the remaining domain name; and splicing the domain name of the current domain with the first element of the rest domain names to obtain the domain name of the lower domain. For example, the domain name of the current domain is [ A ], the domain name of the target domain is [ A, B, B ], the remaining domain name is [ B, B ], and the domain name of the lower domain of the current domain is [ A, B ].
Illustratively, if the domain name of the current domain is not a prefix of the domain name of the target domain, that is, the current domain is an upper-level domain of the target domain, the bridge node in the upper-level domain of the current domain is taken as an intermediate bridge node. For example, the domain name of the target domain is [ a ], the domain name of the current domain is [ a, B ], the domain name of the upper domain of the current domain is [ a, B ], and the bridge node in the domain [ a, B ] is taken as an intermediate bridge node. It should be noted that, the lower domain is transparent to the upper domain, so that the bridge node of the lower domain [ a, B ] may directly transmit data to the directly connected upper domain [ a, B ].
S240, transmitting the data processing transaction request to the intermediate bridge node so that the intermediate bridge node transmits the data processing transaction request to the target node.
According to the technical scheme of the embodiment of the invention, the target domain where the target node is located is determined according to the address information of the target node in the data processing transaction request by responding to the data processing transaction request of the source node, whether the target domain is the same as the current domain where the local node is located is determined, if not, the middle bridging node is selected from the bridging nodes in the first public domain under the condition that the first public domain where the current domain belongs to and the second public domain where the target domain belongs to are the same public domain, and then the data processing transaction request is transmitted to the middle bridging node, so that the middle bridging node transmits the data processing transaction request to the target node. According to the technical scheme, the bridge node is introduced, so that the efficiency of data synchronization of the block chain nodes is improved, meanwhile, under a complex network environment, efficient and safe communication among the block chain nodes is ensured, and the dependence of a node deployment mode on physical network topology is reduced.
Example III
Fig. 3 is a flowchart of a blockchain-based data transmission method according to a third embodiment of the present invention, and provides an alternative implementation manner for further optimizing "determining an intermediate bridge node according to the domain name of the current domain and the domain name of the target domain" based on the above embodiment.
As shown in fig. 3, the method specifically may include:
s310, responding to the data processing transaction request of the source node, and determining the target domain where the target node is located according to the address information of the target node in the data processing transaction request.
S320, determining whether the target domain is the same as the current domain where the local node is located.
S330, if not, selecting an intermediate bridge node from the bridge nodes in the first public domain or the second public domain when the first public domain to which the current domain belongs and the second public domain to which the target domain belongs are not the same public domain.
Optionally, in the case that the first public domain to which the current domain belongs and the second public domain to which the target domain belongs are not the same public domain, selecting an intermediate bridge node from the bridge nodes in the first public domain or the second public domain may be that the local bridge node determines whether the current domain is the current primary domain in the first public domain; if so, taking the first-stage bridging node in the second public domain as an intermediate bridging node; if not, the bridge node in the upper domain of the current domain is taken as an intermediate bridge node.
The current primary domain refers to a primary domain in the first public domain. The primary bridge node refers to a bridge node in the primary domain.
In the case where the first public domain to which the current domain belongs and the second public domain to which the target domain belongs are not the same public domain, the first-level bridge node in the second public domain is used as the intermediate bridge node if the current domain is the current first-level domain in the first public domain.
In an exemplary case where the first public domain to which the current domain belongs and the second public domain to which the target domain belongs are not the same public domain, if the current domain is not the current primary domain in the first public domain, the bridge node in the superior domain of the current domain is taken as an intermediate bridge node.
S340, transmitting the data processing transaction request to the intermediate bridge node so that the intermediate bridge node transmits the data processing transaction request to the target node.
According to the technical scheme of the embodiment of the invention, the target domain where the target node is located is determined according to the address information of the target node in the data processing transaction request by responding to the data processing transaction request of the source node, whether the target domain is the same as the current domain where the local node is located is determined, if not, the middle bridging node is selected from the bridging nodes in the first public domain or the second public domain under the condition that the first public domain where the current domain belongs to and the second public domain where the target domain belongs to are not the same public domain, and the data processing transaction request is transmitted to the middle bridging node, so that the middle bridging node transmits the data processing transaction request to the target node. According to the technical scheme, the bridge node is introduced, so that the efficiency of data synchronization of the block chain nodes is improved, meanwhile, under a complex network environment, efficient and safe communication among the block chain nodes is ensured, and the dependence of a node deployment mode on physical network topology is reduced.
Example IV
Fig. 4 is a flowchart of a data transmission method based on a blockchain according to a fourth embodiment of the present invention, which is further optimized based on the above embodiment, and provides a preferred embodiment.
When data in a block chain network is transmitted, firstly, a source node sends a data transaction processing request to a target node, and the source node judges whether the domain in which the source node is located and the domain in which the target node is located (target domain) are the same domain or not; if yes, the source node transmits a data processing transaction request to the target node according to the Gossip protocol; if not, the source node sends the data processing matter request to the bridge node of the domain where the source node is located, and the bridge node determines an intermediate bridge node according to the domain name of the domain where the source node is located and the domain name of the target domain until the data processing matter request is transmitted to the target bridge node of the target domain, so that the target bridge node transmits the data processing matter request to the target node according to the Gossip protocol.
As shown in fig. 4, the method specifically may include:
s401, starting data transmission.
S402, determining whether the current domain is the same as the target domain; if yes, S408 is executed, and if no, S403 is executed.
Illustratively, when data transmission begins, the current domain is the domain in which the source node is located; for example, referring to fig. 1B, if the source node is node 2, the target node is node 3, and the domain in which the source node is located (current domain) is the same as the target domain, which is domain a, then S408 is performed, that is, node 2 directly transmits the data transaction request to node 3 through the Gossip protocol.
In the data transmission process, the current domain may be the domain where the intermediate bridge node is located, and the intermediate bridge node may be one or a plurality of intermediate bridge nodes. For example, in connection with fig. 1B, the source node is node 2, and the target node is node 6, then the bridge node in domain [ a, a ], the bridge node in domain [ a ], and the bridge node in domain [ B ] need to be passed.
That is, to which node is executed, which domain the node is in is the current domain.
S403, judging whether the current domain is the current primary domain; if yes, S404 is executed, and if no, S405 is executed.
S404, forwarding a data processing transaction request to a primary bridging node of a public domain to which the target domain belongs; and returns to S402, that is, the current domain in S402 is updated to the target primary domain.
S405, judging whether the domain name of the current domain is the prefix of the domain name of the target domain, if so, executing S406; if not, S407 is performed.
S406, determining a lower domain of the current domain, and forwarding a data processing transaction request to a bridge node of the lower domain of the current domain; and returns to S402, i.e., the current domain in S402 is updated to the lower domain of S406.
S407, forwarding a data processing transaction request to a bridge node of a superior domain of the current domain; and returns to S402, i.e., the current domain in S402 is updated to the upper domain of S407.
S408, the data processing transaction request is directly transmitted to the target node, and data transmission is completed.
And the target bridge node of the target domain directly transmits the data processing transaction request to the target node according to the Gossip protocol, so that the data transmission is completed.
According to the technical scheme of the embodiment of the invention, the target domain where the target node is located is determined according to the address information of the target node in the data processing transaction request by responding to the data processing transaction request of the source node, whether the target domain is the same as the current domain where the local node is located is determined, if not, the intermediate bridging node is determined according to the domain name of the current domain and the domain name of the target domain, and the data processing transaction request is transmitted to the intermediate bridging node, so that the intermediate bridging node transmits the data processing transaction request to the target node. According to the technical scheme, the bridge node is introduced, after the network structure is changed, network equipment (namely electronic equipment of the blockchain node) in the domain does not need to be changed, all the equipment can be exposed to the public network, domain names are logically divided, and efficient routing and forwarding can be performed. If the data on the chain of the block chain consensus node is tampered maliciously, the data processing transaction request is preferentially forwarded in the domain due to the existence of the block chain consensus algorithm, so that the information perception of the error by the external node can be reduced, and the probability of being attacked maliciously can be reduced.
