As shown in fig. 1, which is a schematic diagram of a global state continuation decentralized blockchain network node device according to an embodiment of the present invention, and fig. 2, which is a schematic diagram of a global state continuation decentralized blockchain network formed by a global state continuation decentralized blockchain network node device according to an embodiment of the present invention, a node device may include various forms, for example, which may include: personal mobile nodes, personal office nodes, small enterprise nodes, and large enterprise nodes; the various node devices form a global state continuous decentralized block chain network, and meanwhile the global state continuous decentralized block chain network is further connected with a public cloud, wherein each node can be connected with the public cloud to provide an external storage space. In particular, an apparatus for global state persistence and decentralized blockchain network node according to an embodiment of the present invention may include:
the query module is used for receiving the query request and transmitting the query request to the routing module;
the data management module is used for setting the storage space of the node according to the supply consumption ratio, and storing and reading the node information; wherein the node information includes: an upper limit of a node information storage space and a node information attenuation coefficient; the supply consumption ratio is the ratio of the storage space of the node to the storage space required by the node information of the node stored by using the global state continuous decentralized block chain network;

the gossip protocol module is used for transmitting the node information transmitted by other nodes to the data management module for storage according to the upper limit of the node information storage space; and spreading the node information stored by the node to other nodes by using a gossip protocol according to the node information attenuation coefficient.
In an embodiment of the invention, when the global state continues to go to the centralized blockchain network node device, the query module is configured to receive a query request and transmit the query request to the routing module, and may include: in the global state persistent decentralized block chain network, when one node sends out a query request, the query request is sent to the associated node, the query module of the associated node receives the query request, transmits the query request to the routing module, and queries node information on the node or other associated nodes through the routing module.
In an embodiment of the invention, when the global state continues to go to the centralized blockchain network node device provided in the embodiment of the invention is implemented, the routing module is configured to connect the node with other nodes; according to the query request, node information is queried on the node and other nodes connected through the routing table, and the node information comprises the following steps: the routing module is connected with the query module, is provided with a routing table, records the position information of all nodes in the global state continuous decentralized block chain network when each node is accessed to the global state continuous decentralized block chain network, and pushes the position information of the node to other nodes, and the node can be connected with any one or more other nodes in the global state continuous decentralized block chain network through the routing table; the routing module is also used for discovering and recording the positions of other nodes through the routing table. When the routing module receives the query request, whether the node information is stored or not is firstly queried on the node, and if the node information is stored, the node information is returned to the node sending the query request; and if the node does not store the required node information, connecting other nodes through the routing table, and inquiring on other nodes.
In an embodiment of the invention, when the node device of the global state persistent decentralized blockchain network provided by the embodiment of the invention is implemented, the routing module is further configured to, when node information is queried, directly return the node information to a node that sends a query request within a set time interval for the same node information and when the node information is not stored in the node. In the embodiment, because a plurality of nodes exist in the global state persistent decentralized block chain network, the connection between the nodes has the limitation of distance and response time, and in order to acquire the node information required to be queried more quickly, the node information is directly returned to the node sending the query request within a set time interval when the same node information is not stored in the node, so that the node information is queried and responded quickly.
In an embodiment of the invention, when the global state is continuously used to remove the centralized blockchain network node device provided in the embodiment of the present invention, the routing module is further configured to store the required node information in the storage space of the node through the data management module for information maintenance when the required node information is queried on other nodes connected through the routing table.
In the embodiment, because each node has the non-full data storage characteristic, when information is queried, if the node does not store the node information, the final storage position of the node information needs to be queried from the routing table of the node; when the node information is inquired, the node participating in the node information inquiry is concerned about the node information, therefore, when the required node information is inquired on other nodes connected with the routing table, the required node information is stored in the storage space of the node for information maintenance, and the node inquiring the information is added into the maintenance of the node information.
In an embodiment of the invention, when the global state persistence decentralized block chain network node device provided in the embodiment of the present invention is implemented specifically, the data management module is further configured to connect a public cloud as an external storage space of the node when the storage space of the node does not satisfy a supply consumption ratio. The data management module is further configured to provide functions such as data caching.
In an embodiment, the supply consumption ratio is a ratio of a storage space of the node to a storage space required for storing node information of the node by using the global state continuation decentralized blockchain network.
In an embodiment, the supply-consumption ratio is: the ratio of the storage space of the node to the storage space required by the node information of the node stored by using the global state continuous decentralized blockchain network; for example, when the supply/consumption ratio N =100, an enterprise node wants to maintain its own web address (e.g., maintain 1 piece of information) on the global state persistent decentralized blockchain network, and the storage space of the enterprise node has a capacity of at least 100 pieces of information for storing node information of other user nodes. By setting the supply consumption ratio, the storage of the node information can be loaded in each node device, and the consumer holds the node device without paying a third party, so that extra cost is not generated. The aforementioned consumers refer to users who wish to continuously maintain and maintain certain information of themselves. For example, the mobile node may be used as a storage main body for carrying a global state storage decentralized block chain network, so that the node device is miniaturized, and the running data and information are acceptable or imperceptible to the micro device. In a global state persistent decentralized block chain network, a supply consumption ratio is set to N, the information capacity that each customer desires to maintain is enlarged by N times (the numerical value of N can be calculated by a model) as a lower limit of a storage space of a node device, and N is set as a global value. Can be dynamically updated to balance the state of the entire network. That is, an enterprise wants to maintain its own web address (1 message) on the network, the node of the enterprise should have a capacity of at least 100 messages (for example, N = 100) for storing node information of other user nodes. Each piece of node information can ensure the upper limit of the storage space by setting the upper limit of the storage space of the node information. In order to meet the supply consumption ratio and the difficulty of controlling the processing of information in cooperation with the node, it is necessary to set an upper limit M of the node information storage space, for example, each piece of node information may be controlled to 1K, that is, M =1K. Considering that for a user node with a large amount of information required to be issued, the storage space of the user node may require an excessively large capacity due to a supply consumption ratio, which exceeds the upper limit of the storage capacity of a single node. The method can adopt a mode of renting the public cloud, transfer the capacity required to be borne by the enterprise node to the public cloud, connect the public cloud through the data management module, and use the public cloud as an external storage space of the node.
In an embodiment of the present invention, when implementing the global state continuously decentralized blockchain network node device provided in the embodiment of the present invention, the gossip protocol module is configured to store node information transmitted from other nodes according to an upper limit of a node information storage space, and includes: and when the upper limit of the node information storage space of the node information meets the storage space of the node, storing the node information.
In an embodiment of the present invention, when implementing a global state persistent decentralized blockchain network node device provided in the embodiment of the present invention, in an embodiment, the foregoing spreading node information stored in the node to other nodes by using a gossip protocol according to a node information attenuation coefficient includes:
according to the node information attenuation coefficient, spreading the node information stored by the node to other nodes by using a gossip protocol;
and spreading other node information transmitted from other nodes stored in the node to nodes which do not store the node information by using a gossip protocol according to the node information attenuation coefficient.
In the embodiment, one node device stores the node information generated by the node device itself and also stores other node information transmitted by other nodes; when the node information of the node is broadcasted, the node information stored by the node is broadcasted to other nodes by using a gossip protocol according to the attenuation coefficient of the node information; and when other node information transmitted by other nodes is disseminated, the node information of the other nodes stored in the node is disseminated to the node which does not store the node information by using the gossip protocol according to the node information attenuation coefficient.
In particular, when the node apparatus of the global state persistence decentralized block chain network provided in the embodiments of the present invention is implemented, in one embodiment, the attenuation coefficient of the node information is greater than or equal to zero;
the aforementioned dissemination of the node information of the local node stored by the local node to other nodes by using the gossip protocol according to the node information attenuation coefficient includes:
acquiring a node information attenuation coefficient of the node information, and judging whether the node information attenuation coefficient is equal to zero or not;
if the node information attenuation coefficient is equal to zero, the node information stops spreading;
and if the node information attenuation coefficient is larger than zero, subtracting one from the node information attenuation coefficient, and scattering the node information to the nodes which do not store the node information.
In an embodiment, the node information attenuation coefficient refers to that, in a process of transmitting a piece of node information to other nodes, a node data transmission range in which the piece of node information is stored needs to be controlled, so that the total capacity of a network is not too large. When the node information attenuation coefficient is attenuated to 0, the node information is not continuously propagated. For example, when the node information attenuation coefficient P =5, the transmission is performed at most 5 times from the node from which the node information originates. Therefore, after receiving a piece of node information, firstly, the node information attenuation coefficient of the node information needs to be obtained, and whether the node information attenuation coefficient is equal to zero or not is judged; if the attenuation coefficient of the node information is equal to zero, the node information stops being spread, and the node information is only stored in the node; and if the node information attenuation coefficient is larger than zero, subtracting one from the node information attenuation coefficient, and spreading the node information to nodes which do not store the node information. The step of scattering the node information to the nodes which do not store the node information comprises the step of scattering the node information to the nodes concerned about the node information. The node information attenuation coefficient is used for controlling the spreading times of the node information, the node information does not need to be stored on each node in the global state continuous decentralized block chain network, the global information is not recorded, only the local information is recorded, and the local information is controlled according to the capacity of the current node storage space while the node information gradually expands. The repeated storage of the node information on too many nodes is limited by successively attenuating the attenuation coefficient of the node information. When the node information of the node is broadcasted, the node information stored by the node is broadcasted to other nodes by using a gossip protocol according to the attenuation coefficient of the node information, and the method comprises the following steps: acquiring a node information attenuation coefficient of the node information of the node, and judging whether the node information attenuation coefficient is equal to zero or not; if the attenuation coefficient of the node information is equal to zero, the node information stops being spread, and the node information is only stored in the node; and if the node information attenuation coefficient is larger than zero, subtracting one from the node information attenuation coefficient, and spreading the node information to nodes which do not store the node information. The step of scattering the node information to the nodes which do not store the node information comprises the step of scattering the node information to the nodes concerned about the node information.
In an embodiment of the present invention, when the global state is continuously removed from the node apparatus of the centralized blockchain network, the attenuation coefficient of the node information is greater than or equal to zero;
according to the node information attenuation coefficient, spreading other node information transmitted from other nodes stored in the node to nodes which do not store the node information by using a gossip protocol, wherein the method comprises the following steps:
acquiring node information attenuation coefficients of other node information transmitted by other nodes, and judging whether the node information attenuation coefficients are equal to zero or not;
if the node information attenuation coefficient is equal to zero, the node information stops spreading;
and if the node information attenuation coefficient is larger than zero, subtracting one from the node information attenuation coefficient, and spreading the node information to nodes which do not store the node information.
In the embodiment, when the node receives node information transmitted by other nodes and needs to broadcast the node information of the other nodes, the node information attenuation coefficient of the node information of the other nodes transmitted by the other nodes is firstly obtained, and whether the node information attenuation coefficient is equal to zero or not is judged; if the attenuation coefficient of the node information is equal to zero, the node information stops being spread, and the node information is only stored in the node; and if the node information attenuation coefficient is larger than zero, subtracting one from the node information attenuation coefficient, and scattering the node information to the nodes which do not store the node information. The step of scattering the node information to the nodes which do not store the node information includes scattering to the nodes concerned about the node information.

the consensus module is used for temporarily forming a consensus network by the node and the related nodes and carrying out consensus processing on the node information needing consensus;
after the consensus processing is completed, the node information after the consensus processing is stored in the storage space of each node of the consensus network through the data management module.
In an embodiment, consensus techniques are used to form records of more important information. And the node information which needs to be identified is identified, and after the identification is finished, the node information after the identification processing is written into respective storage space.
In an embodiment of the invention, when the node device of the global state continuous decentralized blockchain network provided by the embodiment of the invention is implemented, in the embodiment, the consensus module is further configured to delete the node information in a manner that a plurality of nodes are in consensus when the node information is outdated and the holder of the node information has no capability to delete the node information.
In an embodiment, some node information determined to be no longer used may be submitted by a node held by a consumer to request deletion, and delete a state value in all nodes stored in the node information, so as to empty the node information in the global state existence decentralized blockchain network, thereby avoiding others from querying out-of-date information. When the node information is outdated and the holder of the node information has no ability to delete, the node information is deleted in a mode that a plurality of nodes are commonly identified.
In an embodiment of the present invention, when implementing a global state persistent decentralized blockchain network node device, the node device further includes: and the information processing module is used for recording and updating the node information in the storage space of the node and keeping the node information in the latest state.

Because the principle of solving the problem of the method is similar to that of a global state continuous decentralized blockchain network node device, the implementation of the device can refer to the implementation of the global state continuous decentralized blockchain network node device, and repeated parts are not described again.
