Description

Public chain based block chain network addressing method
Technical Field
The application relates to the technical field of block chains, in particular to a block chain network addressing method based on a public chain.
Background
The main task of the blockchain technology is to create a relatively objective anti-repudiation digital environment based on public consensus according to the decentralized system requirements. Based on the block chain technology, the authenticity of network information can be ensured, for example, a transaction occurs in a block chain network, a node in the network can generate block data for recording transaction contents according to transaction information, the block data is broadcasted in the whole network, and other nodes in the network simultaneously store the block data to form an unalterable block chain. The transaction is generalized, and does not refer to the traditional meaning of "commodity buying and selling" or "commodity exchange", but refers to some data operation content or operation result on the blockchain network, for example, a blockchain node a on the network initiates a query request a for the performance of a communication device of some model, and the query request a is a transaction for a blockchain node B which undertakes a query service. Similarly, the node B sends the performance table B of the communication device of the type obtained by query to the node a, which is also a transaction. Information A, a and information B, b may be written as transaction information in data blocks of a block chain.
It can be seen that a transaction based on blockchain technology is essentially a transaction between two nodes. In the traditional transaction, the initiating node needs to be clear or the address information of the target node is known, so that the target node is found through the address information, and the transaction is completed. However, since the inter-chain transaction occurs between two different blockchains, and the information of each blockchain is independent and incompatible with each other, in the case of inter-chain transaction, a node of one blockchain as a transaction initiator cannot directly acquire address information of a node of another blockchain as a transaction target.
In order to obtain the address information of the target node, an address list of other blockchain nodes may be stored in the current blockchain network, and the address list records the address information of any blockchain in the blockchain set, which can be a transaction target. If the initiating node initiates the transaction, the address information of the corresponding target node needs to be inquired in the address list, and the transaction is carried out with the target node according to the inquired address information. However, this method is only applicable in a network environment where a cross-chain transaction can be performed, which has been signed up. In the actual block chain deployment process, different types of public chains, alliance chains or industry chains are arranged according to different application fields, cross-chain transactions are possible to occur among the chains, and therefore, an address list needs to be stored in each node in each chain, and a large amount of storage resources are occupied.
In addition, most of the blockchains have a dynamic adjustment function, that is, each blockchain has a node to go online or offline at any time, so that the address of the node changes dynamically, and therefore, for any node in the blockchain, the stored address list needs to be updated continuously to adapt to the online or offline of nodes in other blockchains or the change of addresses. This makes the blockchain network need to continuously update the address list, which wastes or occupies more network bandwidth and reduces the transaction efficiency.

Detailed Description
Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following examples do not represent all embodiments consistent with the present application. But merely as exemplifications of systems and methods consistent with certain aspects of the application, as recited in the claims.
In the technical solution provided in the present application, the blockchain refers to accounting data generated by a transaction in a network system, and refers to a network operating a blockchain technology, that is, a blockchain network. The blockchain network refers to a point-to-point (P2P) network with decentralized application architecture, and the blockchain network can perform distributed storage, public consensus, digital encryption, transaction accounting and verification. I.e., a transaction platform that encompasses distributed technology, cryptography, P2P network architecture, and various consensus algorithms that may be applied.
The blockchain or blockchain information is accounting information generated according to transaction information when transactions occur in the blockchain network, namely a plurality of specific transactions form a blockchain, and the plurality of blocks form a blockchain. The blockchain network comprises nodes which establish point-to-point network connection with each other, and each node is configured with a corresponding consensus mechanism, such as an intelligent contract, and has enough computing power to perform transaction verification and accounting procedures. The nodes also have interface specifications that conform to some uniform standard to enable access to more nodes or other types of blockchain networks through the interface specifications.
Referring to fig. 1, a schematic flow chart of a public-link-based block chain network addressing method according to the present application is shown. As shown in fig. 1, the public-chain-based blockchain network addressing method provided in the present application includes the following steps:
s11: the transaction initiating node initiates address query transaction to the address management node in the public chain; part of nodes in the public chain are configured as address management nodes and storage nodes, and the plurality of address management nodes and the storage nodes form an address management network;
in the technical scheme provided by the application, a public chain, a sub-chain and/or a third-party block chain are all point-to-point P2P networks, each P2P network is composed of a plurality of nodes, and each node has independent computing capacity, application running capacity, storage capacity and human-computer interaction capacity. The nodes in the P2P network are not only gateway devices that provide network information transfer, but also any computer devices authenticated by the blockchain network, such as personal computers, computer groups, servers, and intelligent terminal devices.
The transaction initiation node may be any one of the nodes in the system, such as a public link node, a child link node, and a third party blockchain node. The transaction initiation chain node can initiate transactions to other nodes in the system according to actual needs, and the transactions can be virtual currency transactions, for example, virtual currency (evidence) in one block chain network is converted into virtual currency in another block chain network; or an information service transaction, for example, a node in one blockchain network wants to provide a service such as information query, data analysis, etc. through another blockchain network.
The transaction initiating node can initiate an address query transaction according to specific contents in the pre-initiated transaction before initiating a formal transaction, the address query transaction generally aims at finding a transaction target node, and the characteristics of the nodes capable of pre-initiating the transaction can be specified in the address query transaction so as to find the nodes capable of completing the pre-initiated transaction. After the transaction initiating node creates the address query transaction, the address query transaction can be initiated to the address management node.
According to different configuration conditions of actual network systems, the mode of initiating address query transaction from the transaction initiating node to the address management node is different in the application. If the transaction initiating node stores the address information of the address management node, or the transaction initiating node can directly perform information interaction with the address management node, the transaction initiating node can directly initiate address query transaction to the address management node; if the transaction initiating node cannot directly perform information interaction with the address management node or the transaction initiating node and the address management node are not in the same public link network, the transaction initiating node is required to broadcast an address inquiry transaction to the public link network to search the address management node. Specifically, as shown in fig. 2, the step of the transaction initiation node initiating an address query transaction to the address management node in the public chain includes:
s111: extracting a transaction abstract in a pre-initiated transaction;
s112: generating an address query transaction with the transaction abstract through a public link intelligent contract, and judging whether the pre-initiated transaction is a cross-link transaction according to the transaction abstract;
s113: broadcasting the address query transaction to a public link network node if the pre-initiated transaction is not a cross-link transaction;
s114: if the pre-initiated transaction is a cross-link transaction, sending the address query transaction to a parallel link node corresponding to the transaction initiating node;
s115: the parallel link nodes broadcast the address query transaction to the public link network.
As can be seen from the above steps, in this embodiment, the requirement that the transaction target node specified by the pre-initiated transaction should meet may be determined by extracting the transaction digest in the pre-initiated transaction. And generating address query information with a transaction abstract through a public link intelligent contract. After the address query information is generated, whether the pre-initiated transaction is a cross-chain transaction can be judged according to the service content specified in the transaction abstract, and the specific judgment method can be used for finishing the pre-initiated transaction in the current blockchain network range according to whether the service content specified in the transaction abstract can be finished, for example, the pre-initiated transaction is a certificate-based transfer, namely, one node in the same chain wants to transfer a specified number of certificates to another node, and the transfer transaction does not need to be carried out in a cross-chain manner, so that the pre-initiated transaction is not a cross-chain transaction.
In addition, in the mode of determining whether the transaction summary is the cross-chain transaction or not, a conversion rule can be specified in a public chain intelligent contract to generate the transaction summary with a specific coding identifier, and the coding identifier is directly extracted in the judging process to judge whether the transaction is the cross-chain transaction or not.
In practical application, if the pre-initiated transaction is judged not to be a cross-link transaction, the address query transaction can be directly broadcast to the public link network node, so that the address management node in the public link network can receive the address query transaction to feed back the address information of the transaction target node. If the pre-initiated transaction is judged to be a cross-chain transaction, due to the fact that the transaction forms between different chains are different, the address query transaction needs to be further broadcast. Specifically, the following cases may be included:
if the sub-chain where the transaction initiating node is located is configured with an intelligent contract form of a public chain network, the intelligent contract of the public chain network can be directly butted with a public chain node so as to broadcast the address query transaction in a public chain range; if the sub-chain where the transaction initiating node is located is not configured with the intelligent contract of the public chain network, if the sub-chain where the transaction initiating node is located is a formed third-party block chain network, the transaction initiating node needs to firstly send the address query transaction to the corresponding parallel chain node, and then the address query transaction is sent to the public chain network through the bridging effect of the parallel chain node so as to be broadcast in the public chain network range.
It should be noted that, in the technical solution provided in the present application, the parallel chain means that some nodes in the public chain and/or the sub-chain (third party block chain) are configured to be able to perform all data operations of the public link node, and have all functions and information of the public link node; and is also configured to be able to perform all data operations of the third party blockchain node, with all functionality and information of the third party blockchain node. In practical application, the parallel chain nodes can transmit information of the transaction during the transaction and bridge the transaction.
Further, the parallel chain node stores therein address information of neighboring address management nodes, and the method further includes: the parallel chain nodes send the address query transaction directly to neighboring address management nodes.
In practical application, if the scale of the whole block chain system is huge and a plurality of sub-chains or third-party block networks are accessed to a public chain, the nodes in the public chain can be divided according to geographical positions or network topological relations, each sub-area can comprise at least one address management node, and the address management nodes can also mainly inquire and feed back transaction target link addresses aiming at the addresses in the current area.
In practical application, because the parallel chain is used as a connection network of the third-party block chain network and the public chain network, the parallel chain nodes can store the addresses of the adjacent address management nodes, so that the address query transaction can be directly sent to the nearest address management node through the parallel chain nodes, the time consumed by broadcasting the address query transaction is avoided, and the transaction completion efficiency is improved.
S12: and the address management node generates address query information according to the address query transaction and broadcasts the address query information in an address management network.
In the technical solution provided by the present application, the number of the address management nodes may be multiple, and a network based on a block chain technology, that is, an address management network, may also be formed among multiple address management nodes. In the address management network, the address management node may be further configured, for example, a node with better data processing performance may be configured to perform data transceiving, parsing and address query, so as to have sufficient processing performance even in high concurrent transactions; the nodes with larger storage space can be configured to store address data, that is, storage nodes, so as to fully utilize the data processing capacity of the nodes for distributed storage.
In the storage node, not only the address index table of each node and each node in the access chain is stored, but also the verification data and the block data generated in the process of completing the address query transaction can be stored, so that the address query result is booked, and the anti-repudiation effect is generated. In addition, in order to improve the security of data in the system, the data of the same node can be simultaneously and respectively stored in a plurality of storage nodes, and after the address management node broadcasts address inquiry information in an address management network, the address inquiry transaction is respectively verified so as to obtain the most accurate address information of the transaction target node.
S13: and the storage node in the address management network matches the address information of the transaction target node in the address index table according to the address query information.
After receiving the address query information, the node in the address management network may match the address data corresponding to the address query information in the address index table stored in the node itself, and if the address information of the transaction target node is matched in the address index table, the corresponding address information of the target node may be extracted to complete the addressing process.
According to the technical scheme, the address management nodes need to perform information matching through the address index table, so that the address management nodes need to be created in advance, and the stored address management nodes need to be updated continuously to adapt to the nodes in the system to be online and offline. Therefore, in some embodiments of the present application, as shown in fig. 3, the method further comprises:
s131: the address management node periodically broadcasts address confirmation information;
s132: the node receiving the address confirmation information feeds back the current address information to the address management node; the current address information is one of a network address, a terminal MAC address and a unified identification address of the node;
s133: and the address management node creates and/or updates the table entry in the address index table according to the current address information.
In this embodiment, the address index table in the address management node may be updated in a manner that the address management node actively checks the address, that is, the address management node may broadcast the address acknowledgement information once every preset time, and the broadcast address acknowledgement information may be distributed to each sub-chain and the third-party blockchain network from the public chain, so that the node in the sub-chain may feed back the current address information to the address management node after receiving the address acknowledgement information.
In order to adapt to the unified standard of the public link network, in the present application, the current address information fed back by each node may include one or more of a network address, a terminal MAC address, and a unified address identifier. The network address can be an Ethernet address, an IP address and the like in a network, and is suitable for node address management in a network system environment established according to the current Internet; the terminal MAC address is used as a unique identification of a terminal, and address management can be performed when a node is a single device, for example, when a node only includes a PC terminal; the unified address identifier may be a network address form agreed in advance, which may be adapted to all node types, but needs to translate the address management rule of the network node in advance.
In practical application, the unified address identifier can perform corresponding conversion with other address data, obviously, the unified address identifier can satisfy a many-to-many relationship with the terminal device, that is, one unified address identifier can correspond to a plurality of terminal devices in one node; the same terminal device may also have multiple uniform address identifiers according to different roles of the terminal device in different blockchain networks, for example, the same node may have service contents of both information query and data processing, and may simultaneously serve as a node of an information query sub-chain and a data processing sub-chain, and at this time, the node may have multiple uniform address identifiers. However, under the same function (or transaction), one node can only correspond to one uniform address identifier so as to achieve the purpose of addressing.
After each node feeds back the current address information, the address management node may process the fed-back information, such as parsing, format conversion, data extraction, and convert the fed-back current address information into a format specification corresponding to the address index table. And storing the corresponding data in the address index table to complete the updating of the address data. Obviously, in practical applications, the address information fed back by the node may be the same as the previously stored address information, that is, the node address is not changed; or may be different from the previously stored address information, i.e. the node address changes. If the node address is changed, the table entry corresponding to the address index table can be replaced by the changed data.
In addition, the corresponding updated data may also include address information of newly accessed nodes, which are not contained in the stored address index table. Thus, a new entry may be created in the address index table for the address information of the new access node. Obviously, the address index table should include the corresponding nodes: terminal data, address information, and service content, etc.
The above embodiment mainly depends on the way in which the address management node actively sends the address acknowledgement information, and this way does not need to additionally configure the node in the child chain or the third-party blockchain network, and can be directly interfaced with the existing blockchain network, so as to reduce the cost investment at the initial stage of operation and maintenance. However, in practical applications, if the address index table is periodically updated in the above manner, part of the network bandwidth is occupied each time the address index table is updated, and the update period can be appropriately extended to avoid occupation of the network bandwidth. In order to maintain a certain real-time update function in the process of extending the update period, in some embodiments of the present application, as shown in fig. 4, the method further includes:
s134: the new access node encrypts the current address information into an address public key according to an address encryption algorithm of the public link network, and broadcasts the address public key in the public link network;
s135: the address management node which receives the address public key analyzes the address public key to obtain current address information;
s136: and the address management node broadcasts the current address information in the address management network so as to store the current address information in an address index table of a storage node.
In this embodiment, the new access node actively sends address information to the address management node, and the node address data can be stored when each node is online, so as to update the address index table. In practical application, in order to improve the security of the new access node and avoid the danger of being easily attacked due to broadcasting address information, the new access node can be limited to encrypt the current address information according to an address encryption algorithm of a public link network, namely, an address public key is generated. The address encryption algorithm may be a HASH algorithm specified in the public link network, for example, a HASH value obtained by a 64-bit encryption algorithm is used as the address public key.
After generating the address public key, the new access node may broadcast the address public key, where the specific broadcast form may be the same as a common broadcast form, but needs to meet the specification requirement specified by the public link network, so that the address management node may receive the address public key. After the address management node receives the address public key, the address public key may be parsed and broadcast in the address management network to be stored in the corresponding address index table.
S14: and the storage node sends the address information to the transaction initiating node.
In practical application, after the storage node extracts the address information, the storage node can send the address information to a node for data processing and analysis in an address management network, and the node judges whether the address information is complete or not and whether the address information format can be identified by the transaction initiating node or not through a built-in screening program. And when the address information format can not be directly identified by the transaction initiating node, the format of the extracted address information is converted so as to adapt to the addressing requirements of various different third-party block chain networks.
According to the technical scheme, part of nodes in the public link network can be configured as address management nodes, so that when a transaction occurs, the transaction is quickly positioned to a transaction target node through address query transaction and an address index table stored in the address management nodes.
In another embodiment of the present application, there is also provided a public-chain-based blockchain network addressing method, as shown in fig. 5, the addressing method includes the following steps:
s21: the transaction initiating node inquires the transaction from the public link broadcast address; part of the nodes in the public chain are configured as address management nodes;
s22: the address management node which receives the address query transaction broadcasts address query information in a public link and/or a sub-link accessed to the public link within a specified range;
s23: the public link node or the sub-link node which receives the address query information feeds back the current address information to an address management node according to the address query information;
s24: and the address management node sends the current address information to the transaction initiating node.
The difference between this embodiment and the above embodiments is that in this embodiment, the address management node may not store an address index table, but broadcast the address query information in the public link or the sub-link range through the address management node, so that the node receiving the address query information may feed back the address information to the address management node, and send the address information to the transaction initiating node through the address management node. In the embodiment, the address management node directionally broadcasts the nodes in the designated range, so that in practical application, each transaction can be prevented from being addressed in the whole network range, and the transaction efficiency is improved.
In order to implement broadcasting address query information in a public chain and a sub-chain within a specified range, the public chain node is divided into a plurality of sub-areas, each sub-area includes at least one address management node therein, as shown in fig. 6, the method further includes:
s221: the address management node receiving the address query transaction broadcasts address query information in the sub-area to which the address management node belongs;
s222: if the node in the subzone does not feed back the address information to the address management node, the address management node broadcasts the address inquiry information to the subzone adjacent to the subzone.
The public chain sub-regions can be divided according to the geographical position of the node, different sub-chains connected with the node and different roles configured by the node. Since the transmission time of the nodes in the adjacent address area is short and the functions generally tend to be consistent, the present application prefers the technical scheme of dividing according to the geographical position. In practical applications, the address management node receiving the address query transaction may preferentially broadcast the address query information in the sub-area to which the address query transaction belongs. If a transaction target node meeting the pre-initiated transaction exists in the sub-area, the node can feed back the current address information to the address management node.
If the sub-area does not have the transaction target node meeting the pre-initiated transaction, the address query information needs to be further broadcast to the sub-areas adjacent to the sub-area until the node feeds back the current address information to the address management node. Therefore, in the embodiment, addressing in the whole network range can be avoided through a reasonable fragmentation mechanism, so that the acquisition time of the address of the transaction target node is shortened, and the addressing efficiency is improved. And the mode of firstly broadcasting in the sub-area and then broadcasting from the adjacent area of the sub-area can occupy the network bandwidth to the minimum extent on the basis of avoiding the addressing failure.
Further, as shown in fig. 7, if the sub-chain accessing the public chain includes a third party block chain, the third party block chain is connected to the public chain through a parallel link, the address management node receiving the address query transaction broadcasts the address query information in the public chain and/or the sub-chain accessing the public chain within a specified range, including:
s223: the address management node broadcasts the address query information to the parallel chain nodes;
s224: and broadcasting the address query information in the third-party block chain by the parallel chain node according to an intelligent contract form corresponding to the third-party block chain.
In practical application, the third-party blockchain network cannot directly receive the broadcast address query information of the address management node because the third-party blockchain has an independent blockchain transaction mode and an independent accounting mode. Therefore, the address management node can broadcast the address query information to the parallel chain corresponding to the third-party block chain. And then the address query information is converted through the parallel chain according to the intelligent contract of the third-party block chain, and the address query information is broadcasted in the third-party block chain network, so that the forwarding and transaction bridging of the address query information are realized.
Accordingly, as shown in fig. 8, the method further comprises the steps of:
s225: the third-party block chain link point receiving the address query information judges whether the transaction specified by the address query information can be completed according to a preset transaction type;
s226: if the third-party block link node can complete the transaction specified by the address query information, feeding back the current address information to the parallel link nodes;
s227: the parallel chain link points send the current address information to the address management node according to a public chain intelligent contract form;
s228: and if the third-party blockchain node cannot complete the transaction specified by the address query information, broadcasting the address query information to nodes adjacent to the third-party blockchain.
In some embodiments of the present application, as shown in fig. 9, the step of feeding back current address information to an address management node according to the address query information by a public link node or a child link node that receives the address query information includes:
s231: the public link node or the sub-link node which receives the address query information analyzes the address query information and judges whether the transaction specified by the address query information can be completed according to a preset transaction type;
s232: if the public link node or the sub-link node can complete the transaction specified by the address query information, feeding back the current address information to the address management node;
s233: broadcasting the address query information to nodes adjacent to the public link node or the sub-link node if the public link node or the sub-link node cannot complete the transaction specified by the address query information.
In practical application, each node receiving the address query information can analyze the address query information according to a preset data transmission protocol, and determine a pre-initiated transaction type specified in the address query transaction. And then, whether the node can be used as a transaction target node is determined by comparing the transaction type supported by the node with the transaction type supported by the node.
Therefore, in the embodiment, the address query information can be broadcast in the specified range, so that the whole network broadcast is converted into the partial network broadcast, the broadcast form of most of the P2P networks can be adapted, the addressing time of the blockchain transaction is shortened, and the transaction efficiency is improved. Moreover, most addressing processes occur in a partial network range, so that the occupation of the whole network bandwidth resource in the broadcasting process can be reduced.
According to the technical scheme, the method enables the sub-chain and/or the third-party blockchain network to form a network system capable of conducting transaction through the public link network, and in the system, part of nodes in the public link network are configured as address management nodes and can inquire the address information of the transaction target node according to the address sent by the transaction initiating node. And the address of the transaction target node is quickly determined by matching the address index table and broadcasting the address query information, so that the transaction initiating node and the transaction target node can perform subsequent transactions. According to the addressing method, the address information of the transaction target node can be obtained through the address management node, so that each transaction is prevented from being subjected to broadcast addressing, and/or the address index table is prevented from being stored and updated in each node, therefore, the occupation of network bandwidth in the addressing process can be reduced, and the transaction efficiency is improved.
The embodiments provided in the present application are only a few examples of the general concept of the present application, and do not limit the scope of the present application. Any other embodiments extended according to the scheme of the present application without inventive efforts will be within the scope of protection of the present application for a person skilled in the art.
