Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a method for inter-node communication of a block chain according to an embodiment of the present invention. The embodiment of the invention provides a method for communication between block chain nodes aiming at the technical problems in the prior art, which comprises the following specific steps:
As shown in fig. 3, 31 denotes a master storage node in the blockchain Network, 32 denotes a slave storage node in the blockchain Network, 33 denotes a target node, the target node 33 requests to become the slave storage node, the target node 33 does not have a public Network IP Address, the target node 33 communicates with the blockchain Network through Network Address Translation (NAT), 34 denotes a NAT, 35 denotes an inquiring node in the blockchain Network, and in the present embodiment, the inquiring node 35 is provided with an inquiry service by the slave storage node. The method is only illustrative and does not limit the specific network architecture of the blockchain network.
When the query node 35 first joins the block chain network, it is necessary to obtain the created blocks from the nodes adjacent to the query node 35, and optionally, all the nodes in the block chain network store the created blocks. In order to ensure that the query node 35 obtains a real created block, the query node 35 may send created block query requests to a plurality of neighboring nodes, for example, the query node 35 sends created block query requests to the neighboring node B1 and the neighboring node C1, after receiving the created block query requests, the neighboring node B1 and the neighboring node C1 send respective locally stored created blocks to the query node 35, the query node 35 compares whether the created blocks fed back by the neighboring node B1 and the neighboring node C1 are consistent, and if the created blocks fed back by the neighboring node B1 and the neighboring node C1 are consistent, the query node 35 locally stores the created blocks; if the created blocks fed back by the neighboring node B1 and the neighboring node C1 are not consistent, the query node 35 may further continue to send created block query requests to the neighboring node D1 and the neighboring node E1, and receive created blocks fed back by the neighboring node D1 and the neighboring node E1, respectively, and if created blocks fed back by neighboring nodes exceeding a preset proportion among the neighboring node B1, the neighboring node C1, the neighboring node D1, and the neighboring node E1 are consistent, the query node 35 determines that the created blocks are real. Optionally, more than fifty percent of neighboring nodes, such as the neighboring node C1, the neighboring node D1, and the neighboring node E1, of the neighboring node B1, the neighboring node C1, the neighboring node D1, and the neighboring node E1 respectively feed back the same created blocks, and then the query node 35 determines that the created blocks fed back by the neighboring node C1 are real, and the created blocks fed back by the neighboring node B1 are false.
When the query node 35 acquires the real created block, the created block is stored locally, the IP address of the main storage node is acquired from the created block, and a query request for querying the secondary storage node is sent to the main storage node according to the IP address of the main storage node. For example, the querying node 35 sends a query request to the main storage node 31, the query request including identification information of the querying node 35.
In the present embodiment, the master storage node 31 locally stores a list including identification information of slave storage nodes corresponding to the master storage node 31 and public network IP addresses, for example, the list includes identification information of the slave storage node 32 and public network IP addresses.
When the main storage node 31 receives the request information sent by the target node 33, it is determined that the target node 33 does not have a public network IP address, but the target node 33 wants to become a slave storage node, the main storage node 31 records the identification information of the target node 33 and the terminal device number corresponding to the target node 33 in the list. The public key of the slave storage node 32 and the public key of the target node 33 may be stored in the list.
In this embodiment, since the slave storage node 32 does not communicate with the blockchain network through the NAT, the slave storage node 32 has a public network IP address, and the master storage node 31 locally stores the public network IP address of the slave storage node 32; the target node 33 communicates with the blockchain network through the NAT, and the target node 33 does not have a public network IP address, and the main storage node 31 does not locally have the public network IP address of the target node 33; however, it is necessary to have a public network IP address as a slave storage node in order for the inquiring node to access the slave storage node based on the public network IP address. Therefore, in this embodiment, the target node 33 needs to send a heartbeat message to the main storage node 31 in real time or periodically, and it is assumed that the heartbeat message sent by the target node 33 and received by the main storage node 31 at a certain time is marked as a first heartbeat message, where the content included in the first heartbeat message may specifically be a content index, such as a block number, which can currently provide storage information query and is signed by the target node 33 using its own private key.
After the main storage node 31 receives the first heartbeat packet, according to the signed block number in the first heartbeat packet, the identity information of the target node 33 may be determined, and the source IP address and the source port number of the first heartbeat packet are further extracted, where the main storage node 31 may use the source IP address and the source port number of the first heartbeat packet as the address information of the target node 33, and optionally, the address information of the target node 33 includes: a public network IP address of the access point AP corresponding to the target node 33 and a port number mapped on the public network IP address by the target node 33. In addition, the public network IP address may also be a public network IP address of a local area network to which the target node 33 belongs. That is to say, the source IP address of the first heartbeat packet may be a public network IP address of an access point AP corresponding to the target node 33, or a public network IP address of a local area network to which the target node 33 belongs; the source port number of the first heartbeat packet may be the port number mapped on the public network IP address by the destination node 33.
The main storage node 31 records the identification information of the target node 33, the terminal device number corresponding to the target node 33, and the public network IP address and port number corresponding to the target node 33 in a local list.
After receiving the query request of the query node 35, the main storage node 31 determines whether the target node 33 is a node under the symmetric NAT, which includes the following specific steps: the main storage node 31 checks a locally stored blockchain account book, detects whether a node M exists in the blockchain account book, and during a communication process between the node M and the node a, the node M actively contacts the node a through an IP address of the node a, but not the node M that the node a contacts first, if the node M exists, the main storage node 31 determines that the target node 33 is not a node under the symmetric NAT, and if the node M does not exist, the main storage node 31 determines that the target node 33 is a node under the symmetric NAT, further, the main storage node 31 acquires a public network IP address and a port number corresponding to the target node 33 from a local list, and it can be understood that the public network IP address and the port number corresponding to the target node 33 are determined by the main storage node 31 through a heartbeat message reported by the target node 33.
Specifically, the sending, by the master storage node, the query request to the at least one slave storage node according to the address information of the at least one slave storage node includes: and the main storage node sends the query request to the target node according to the address information of the target node, and the target node is communicated with a block chain network through symmetrical network address translation.
After the main storage node 31 acquires the public network IP address and the port number corresponding to the target node 33 from the local list, the main storage node 31 sends the query request sent by the query node 35 to the target node 33 according to the latest public network IP address and port number corresponding to the target node 33, that is, the main storage node 31 may send the query request sent by the query node 35 to the target node 33 through a heartbeat channel between the main storage node 31 and the target node 33, and after receiving the query request of the query node 35, the target node 33 sends the corresponding query result to the query node 35.
In the embodiment of the invention, the heartbeat message sent by the target node is received through the main storage node, and the heartbeat message comprises the address information of the target node, so that the main storage node records the corresponding relation between the identification information of the target node and the address information of the target node, and the target node can become a slave storage node in a block chain network, so that the node without a public network IP address can also become the slave storage node, and the development of block chain service is promoted.
Fig. 4 is a flowchart of a method for inter-node communication of a block chain according to another embodiment of the present invention. On the basis of the foregoing embodiment, before the main storage node receives an inquiry request sent by an inquiry node, where the inquiry request includes identification information of the inquiry node, the block inter-link node communication method provided in this embodiment further includes the following steps:
In this embodiment, when the target node 33 first joins the blockchain network, it is necessary to obtain the created blocks from the nodes adjacent to the target node 33, and optionally, all the nodes in the blockchain network store the created blocks. In order to ensure that the target node 33 obtains a real created block, the target node 33 may send created block query requests to a plurality of neighboring nodes, for example, the target node 33 sends created block query requests to the neighboring node B and the neighboring node C, after receiving the created block query requests, the neighboring node B and the neighboring node C send respective locally stored created blocks to the target node 33, the target node 33 compares whether created blocks fed back by the neighboring node B and the neighboring node C are consistent, and if created blocks fed back by the neighboring node B and the neighboring node C are consistent, the target node 33 locally stores the created blocks; if the created blocks fed back by the adjacent node B and the adjacent node C are not consistent, the target node 33 may further continue to send created block query requests to the adjacent node D and the adjacent node E, and receive created blocks fed back by the adjacent node D and the adjacent node E, respectively, and if the created blocks fed back by adjacent nodes exceeding a preset proportion among the adjacent node B, the adjacent node C, the adjacent node D, and the adjacent node E are consistent, the target node 33 determines that the created blocks are real. Optionally, if the created blocks fed back by more than fifty percent of the neighboring nodes, such as the neighboring node C, the neighboring node D, and the neighboring node E, are consistent, the target node 33 determines that the created block fed back by the neighboring node C is real, and the created block fed back by the neighboring node B is false.
When the target node 33 acquires a real created block, the created block is stored locally, the IP address of the main storage node is acquired from the created block, and request information is sent to the main storage node according to the IP address of the main storage node, where the request information is used to indicate that the target node 33 wants to become a slave storage node, and the request information includes identification information of the target node 33, a terminal device number corresponding to the target node 33, and indication information used to indicate that the target node 33 has no public network IP address, and the indication information may be a field or a character agreed in advance in the block chain network.
In this embodiment, the master storage node 31 locally stores a list including identification information of a slave storage node corresponding to the master storage node 31, a terminal device number corresponding to the slave storage node, and a public network IP address, for example, the list includes identification information of the slave storage node 32, a terminal device number corresponding to the slave storage node 32, and a public network IP address.
When the main storage node 31 receives the request information sent by the target node 33, it is determined that the target node 33 does not have a public network IP address, but the target node 33 wants to become a slave storage node, the main storage node 31 records the identification information of the target node 33 and the terminal device number corresponding to the target node 33 in the list. The public key of the slave storage node 32 and the public key of the target node 33 may be stored in the list.
Optionally, the address information of the target node includes: and the public network IP address of the access point AP corresponding to the target node and the port number mapped on the public network IP address by the target node.
In this embodiment, since the slave storage node 32 does not communicate with the blockchain network through the NAT, the slave storage node 32 has a public network IP address, and the master storage node 31 locally stores the public network IP address of the slave storage node 32; the target node 33 communicates with the blockchain network through the NAT, and the target node 33 does not have a public network IP address, and the main storage node 31 does not locally have the public network IP address of the target node 33; however, it is necessary to have a public network IP address as a slave storage node in order for the inquiring node to access the slave storage node based on the public network IP address. Therefore, in this embodiment, the target node 33 needs to send a heartbeat message to the main storage node 31 in real time or periodically, and it is assumed that the heartbeat message sent by the target node 33 and received by the main storage node 31 at a certain time is marked as a first heartbeat message, where the content included in the first heartbeat message may specifically be a content index, such as a block number, which can currently provide storage information query and is signed by the target node 33 using its own private key.
After the main storage node 31 receives the first heartbeat packet, according to the signed block number in the first heartbeat packet, the identity information of the target node 33 may be determined, and the source IP address and the source port number of the first heartbeat packet are further extracted, where the main storage node 31 may use the source IP address and the source port number of the first heartbeat packet as the address information of the target node 33, and optionally, the address information of the target node 33 includes: a public network IP address of the access point AP corresponding to the target node 33 and a port number mapped on the public network IP address by the target node 33. In addition, the public network IP address may also be a public network IP address of a local area network to which the target node 33 belongs. That is to say, the source IP address of the first heartbeat packet may be a public network IP address of an access point AP corresponding to the target node 33, or a public network IP address of a local area network to which the target node 33 belongs; the source port number of the first heartbeat packet may be the port number mapped on the public network IP address by the destination node 33.
The main storage node 31 records the identification information of the target node 33, the terminal device number corresponding to the target node 33, and the public network IP address and port number corresponding to the target node 33 in a local list.
In addition, in another embodiment, after the main storage node records the correspondence between the identification information of the target node and the address information of the target node in step 404, the method further includes: the main storage node receives a second heartbeat message sent by the target node; and the main storage node updates the address information of the target node stored by the main storage node according to the address information of the target node included in the second heartbeat message.
In this embodiment, the target node 33 may send a heartbeat message to the main storage node 31 in real time or periodically, and it is assumed that after the target node 33 sends the first heartbeat message described in the above embodiment to the main storage node 31, a second heartbeat message is sent to the main storage node 31, a source IP address of the second heartbeat message may be different from a source IP address of the first heartbeat message, and a source port number of the second heartbeat message may also be different from a source port number of the first heartbeat message, that is, the source IP address and the source port number of the heartbeat message may be changed.
When the main storage node 31 receives the second heartbeat packet, the source IP address and the source port number of the second heartbeat packet may be used as new address information of the destination node 33.
Before the main storage node 31 receives the second heartbeat message, the main storage node 31 locally stores identification information of the target node 33, a terminal equipment number corresponding to the target node 33, a public network IP address and a port number corresponding to the target node 33; after the main storage node 31 receives the second heartbeat message, the source IP address of the second heartbeat message is used as the new public network IP address of the target node 33, and the source port number of the second heartbeat message is used as the new port number of the target node 33, so that the public network IP address and the port number of the target node 33, which are already stored in the main storage node 31, are updated according to the new public network IP address and the new port number of the target node 33.
In the embodiment of the invention, the heartbeat message sent by the target node is received through the main storage node, and the heartbeat message comprises the address information of the target node, so that the main storage node records the corresponding relation between the identification information of the target node and the address information of the target node, and the target node can become a slave storage node in a block chain network, so that the node without a public network IP address can also become the slave storage node, and the development of block chain service is promoted.
