Description
Technical Field
The invention relates to the technical field of blockchains, in particular to a block propagation method, a system, a storage medium and electronic equipment based on acquaintance immune strategies.
Background
Blockchain is a distributed database with decentralization property, is now known to be applied in the financial field, is the bottom technology of various encrypted currencies such as bitcoin, and has the characteristics of transparency, non-tamper property, anonymity, traceability and the like. In a decentralised system, the gossip protocol is a popular choice for point-to-point communication, typical applications being Bitcoin, ethereum and risple et al.
However, the transaction processing capacity of current common blockchain systems is not high, with a bit coin per second transaction amount (TPS) of only around 7. Low transaction processing capability limits the application scenarios of blockchains. Simply increasing the block volume to accommodate more transactions to increase TPS increases the propagation delay of the block, thereby increasing the rate of solitary blocks and reducing system security. Some methods of accelerating block propagation often require altering the data structure of the block, removing some of the block verification procedures, or changing the topology of the node network. These approaches vary widely from existing systems and tend to have significant drawbacks, such as the structured network reducing the security of the blockchain system.
Block relay refers to a method that when a node cannot directly transfer a new block to other nodes in a block chain network, it sends the block to a relay node, and the relay node broadcasts the block to other nodes. This helps to ensure that all nodes in the network have the same blockchain state, block relay is used to ensure that nodes can receive new blocks in time and update their state. The block relay method of the common public chain cryptocurrency system is as follows: the block is sent directly to several first-order neighbor nodes, each of which continues to send to its own first-order neighbor node (note that the neighbor nodes that have received the block are not sent repeatedly) until all nodes receive the block.
Acquaintance immunity is one of epidemic immunity strategies in a complex network, and is characterized by no need of global topology information and excellent performance in a scaleless network. The basic idea of the acquaintance immune algorithm is: and randomly selecting a certain proportion of nodes from the nodes, and randomly selecting a neighbor node from each selected node for immunization. In the complex network domain, first-order neighbor nodes refer to nodes that are directly connected to a given node.
In view of this, it is necessary to provide a block propagation scheme based on acquaintance immunization strategies.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment of the application solves the technical problem that the transaction processing capacity of the conventional public blockchain system needs to be improved by providing the block propagation method, the system, the storage medium and the electronic equipment based on the acquaintance immune strategy.
The technical scheme in the embodiment of the application aims to solve the technical problems, and the overall thought is as follows:
in a blockchain network, each node may have a plurality of neighbor nodes, and the neighbor nodes may be first-order neighbor nodes or higher-order neighbor nodes. The acquaintance immunization strategy only needs to know the randomly selected nodes and the first-order neighbor node information thereof, so that global node information is not needed. Because some nodes with large degrees are directly connected with a plurality of nodes in the scale-free network, the nodes selected by the method have a high probability of selecting the nodes with large degrees.
Because public chains (such as bitcoin) are often topologically hidden and resist the behavior of snooping topological structures, the application uses acquaintance immune algorithms without global information, avoids the requirement on the topological information of global nodes of the blockchain, selects more suitable nodes to propagate the blocks, and reduces the propagation time of the blocks.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
Examples:
as shown in fig. 1, a block propagation method based on acquaintance immune strategy, based on a blockchain system, includes:
s1, determining a plurality of relay nodes in neighbor nodes of a block creation node by adopting acquaintance immune strategies;
and S2, based on the block creation node, the block is sent to each relay node, and the relay node receives the block after verification and broadcasts the block to the whole network.
The embodiment of the invention reduces the propagation delay of the blocks by improving the epidemic propagation protocol of the existing blockchain system, thereby reducing the average block interval, generating more blocks in shorter time and improving the transaction amount per second. The existing system is not changed greatly, the main data structure and the network structure are not changed, and the deployment and the realization are easy.
The following will describe each step of the above technical solution in detail:
in step S1, among the neighboring nodes of the block creation node, a plurality of relay nodes are determined by using an acquaintance immune policy.
The neighbor nodes comprise first-order neighbor nodes and second-order neighbor nodes determined through GETADDR messages.
In the step, top-k nodes with the front occurrence frequency are selected from the second-order neighbor nodes to serve as relay nodes; the acquaintance immunization strategy includes:
s100, initializing a candidate list C=N\ { i }; on the premise of not removing the repeated nodes, N represents a second-order neighbor node list of the block creation node; i, creating a node for the block;
s200, if count j ＝max(count 1 ,count 2 ,…count l ,…count L ) The method comprises the steps of carrying out a first treatment on the surface of the Wherein the number of non-repeated nodes in C is L; j represents a node to be analyzed; count (count) l Representing the frequency of occurrence of node l in C;
s300, selecting a node j, updating a candidate list C=C\ { j }, and enabling L=L-1;
s400, repeating S200-S300 until k nodes are selected.
In step S2, the block is sent to each relay node based on the block creation node, and the relay node accepts the block after verification is passed and broadcasts the block to the whole network.
Wherein, the relay node accepts the block after passing the verification, which means that:
(1) If the IP address of the block creation node is in the address list of the current relay node, checking whether the hash of the block accords with the target difficulty of the system and whether the transaction of the block is effective, and accepting the block after the block passes the check; or alternatively
(2) If the IP address of the block creation node is not in the address list of the current relay node, verifying whether the address of the block creation node is consistent with the output address of the Coinbase transaction in the block, if so, checking whether the hash of the block accords with the target difficulty of the system and whether the transaction of the block is effective, and accepting the block after the pass of the check.
It is easy to understand that in the point (2), the sender information, which is the block creation node, is verified in advance, so that the flooding attack of the malicious node can be effectively avoided.
The embodiment of the invention takes the most popular cryptocurrency bit coin as an example. In a bitcoin p2p network, each node maintains a list of IP addresses of several other nodes, from which a bitcoin node selects a maximum of 8 (default) nodes as outbound connections for sending messages such as transactions and blocks. Each node may accept up to 117 (default) inbound connections or choose not to accept inbound connections. When the original outbound connection is not available, such as when the outbound neighbor node closes the connection or the node reboots, the node selects a new outbound connection. Generally, about 20% to 50% of the connections in a coin network can last for at least one week, which lays a foundation for the successful implementation of the present application.
Bitcoin is topologically hidden and resists the behavior of snooping topologies, thus employing the acquaintance immune algorithm described above that does not require global information. Each node in the bit coin network counts own first-order neighbor information, and a second-order neighbor node information list is obtained through GETADDR information. 8 (default) nodes are selected from the obtained node information list according to the sequence of the occurrence frequency from high to low as candidate node lists, except for the miner nodes. After successfully digging out a block meeting the requirements, the miner node immediately sends the block to the nodes in the candidate node list, and when the nodes receive the block, the addresses of the sender and the output addresses of the Coinbase transactions in the block are verified to be consistent, and after the verification is passed, the blocks are connected and received.
Although the bitcoin network may be considered an ER random network, 8 outbound neighbors of a node are randomly selected. In practice, however, most IP addresses appear in the buckets of only a few reachable nodes, while some IP addresses tend to appear frequently in the buckets of a large number of reachable nodes; of the reachable nodes, the first 50% are least frequent, the next 25% show moderate but uneven popularity, and the last 25% are very popular. This represents a very unbalanced popularity of nodes, and a very small fraction of the IP addresses retrieved are very popular, indicating that a real-world bitcoin network may possess a scaleless nature, i.e. a few nodes possess a large number of neighbors. The acquaintance immune algorithm has more remarkable effect in a scaleless network, so that the protocol provided by the embodiment of the invention has excellent effect in practical application.
The embodiment of the invention provides a block propagation system based on acquaintance immune strategy, which is based on a block chain system and comprises the following components:
the node selection module is used for determining a plurality of relay nodes by adopting acquaintance immune strategies in neighbor nodes of the block creation node;
and the block propagation module is used for transmitting the block to each relay node based on the block creation node, and receiving the block after the relay node passes the verification and broadcasting the block to the whole network.

one or more processors; a memory; and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the programs comprising a block propagation method for performing acquaintance-based immunization strategies as described above.
