Description
Technical Field
The invention belongs to the field of block chain research, and particularly relates to an expanding method of an anchor node in a block chain.
Background
The rapid development of block chain technology has brought about several opportunities and challenges to various industries. The characteristics of non-tampering, decentralization and traceability of the block chain realize the dispersive operation of application program development which can only use a centralized architecture before, and realize the same function on the premise of ensuring the same reliability. However, the development of the blockchain itself has risks of poor expansibility and safety, high node maintenance cost, unified breeding, fraudulent transfers of side chains and the like, and the specific contents are as follows:
(1) Expansibility and safety
In terms of the expansibility of the block chain, the script is complex or simple, so that the development and maintenance audit of more functions is not facilitated. The construction of bitcoins solves the problem of all nodes with a standard, which is questionable for the assurance of security for low value and low risk transactions.
(2) The maintenance cost of the node is high
In the blockchain, due to the decentralized characteristic, the verification workload of each node is increased in an excessively large-block and high-speed working mode, and since all records are recorded in the account book content, the operation speed of the node is reduced, and the maintenance cost is increased.
(3) Unified breeding
The protection mechanism of each bitcoin is the same, so that the unified breeding risk of the nodes is increased, namely when one node has a problem, the nodes using the same mechanism generate security threats.
(4) Side chain fraudulent transfer of money
In theory, any deep recombination could be sent and an attacker could completely transfer coins between side chains before the transmission chain cancels the transfer of the half-way, based on the re-sent recombination which is longer than the contention period. The result will be an unequal number of coins in the receive chain to the number of redeemable locked outputs in the transmit chain. If the attacker is allowed to transfer coins back to the original chain, he will increase the number of his own coins, leaving the other users on the side chain to pay for the loss.
Disclosure of Invention
The invention provides the anchor node in the block chain, and expands and refines the functions of the anchor node in the block chain to solve the problems of poor safety and high node maintenance cost of the block chain.
The invention is realized by adopting the following technical scheme: a method for expanding anchor nodes in a block chain comprises the following steps:
(1) Selection of anchor nodes: randomly selecting a common node on a block chain as an anchor node, carrying out transaction by other common nodes, recording the transaction behaviors of other common nodes by the anchor node, summarizing the transaction behaviors of the common nodes, coding the transaction behavior of each common node by using numbers, comparing the transaction data in the transaction behavior of each common node with a set verification workload after transaction of a unit time, carrying out transaction of the next unit time if the transaction data of each common node does not exceed the verification workload, matching the transaction behavior code of each common node in the unit time with the transaction behavior code of the previous time node if the transaction data of a certain common node exceeds the verification workload, and if the matching degree meets the requirement, selecting the anchor node again, and repeating the steps until a proper common node is selected as the anchor node;
(2) Informatization of anchor nodes: when all common nodes carry out transaction, transaction behaviors are synchronously updated and recorded on the anchor node, so that the significance is that although the workload and the work content are increased when the recorded data are updated, the time for dispersing attention can be reduced for a maintainer in the later checking process, and the later work processing efficiency is improved.
In the method for expanding the anchor node in the block chain, when the block chain needs to be changed greatly to solicit agreement of all nodes, the anchor node can quickly conclude through an empirical model to improve the speed, before that, authentication and permission of the anchor node need to be set, and an empirical judgment algorithm of the anchor node is as follows:
1) An authentication module: after the anchor node is determined, the address is broadcasted to each common node, and each common node gives an anchor node authority through a consensus algorithm;
2) A judgment module: and after the administrator makes a decision, all the ordinary nodes vote whether to agree with the decision, and the anchor node records the voting result in the empirical model. When the administrator makes a decision again, the anchor node makes a judgment according to the data in the empirical model, and each transaction node approves the judgment made by the anchor node by default.
In the expanding method of the anchor node in the block chain, the anchor node is selected from the side chain, and the anchor nodes on the main side chain of the block chain are connected to enable the anchor nodes to independently and freely communicate.
The invention divides the nodes in the block chain into common nodes and anchor nodes, wherein the related privacy data can be processed or communicated only through the anchor nodes, thereby achieving the purpose of protecting privacy.
(1) Informatization of anchor nodes: the anchor node grasps all information of each common node. As a verification party, the method can reduce the workload, can quickly locate the key information in a larger block chain, and improves the running speed of the block chain. As miners in the block chain, the operation conditions of the blocks can be known by acquiring data of anchor nodes, and the efficiency and the speed of merging and digging are improved. And only the anchor nodes need to be maintained and recorded, so that the maintenance cost is reduced.
(2) A distributed autonomous management module of the anchor node: and realizing a distributed autonomous management module of the anchor node through a software platform. The module mainly takes the anchor node in each block chain as a main body, records transaction behaviors and results, and approves and simulates judgment of each branch node.
(3) Side chain anchor nodes to resolve side chain fraudulent transfers: the anchor nodes generated on the independent side chains can be independently communicated with the anchor nodes on the main chain, and because each anchor node records the information of all common nodes, when the main side chain performs information interaction and the competition period of the bidirectional anchoring technology has problems, the anchor nodes can play a role in recording information transaction, thereby realizing safety certification and improving the security of the transaction.

Detailed Description
The invention provides an expanding method of anchor nodes in a block chain, the thought chart of which is shown in figure 2, and the expanding method comprises the following steps:
(1) Selection of anchor nodes: randomly selecting a common node on a block chain as an anchor node, carrying out transaction by other common nodes, recording the transaction behaviors of other common nodes by the anchor node, wherein the transaction behaviors comprise transaction modes, transaction times and transaction data, summarizing the transaction behaviors of the common nodes, coding the transaction behavior of each common node by using numbers, comparing the transaction data (the transaction data is the sum of the transaction data of each previous unit time) in the transaction behavior with a set verification workload by each common node after transaction of a unit time, carrying out the transaction of the next unit time if the transaction data of each common node does not exceed the verification workload, matching the transaction behavior codes of each common node in the unit time with the transaction behavior codes of the previous time node if the transaction data of a certain common node exceeds the verification workload, and repeating the steps until the appropriate common node is selected as the anchor node;
(2) Informatization of anchor nodes: when all the common nodes carry out transaction, the transaction behavior synchronous record is updated on the anchor node, and the anchor node does not have the transaction function. The significance of this is that although the workload and the work content are increased when the data is updated, the time for the maintenance personnel to pay attention to the future account checking process can be reduced, and the future work processing efficiency is improved. The anchor node is also responsible for related communication among nodes, provides mining reference data for miners and the like, and can greatly improve the transaction rate in an oversized block chain.
(3) A distributed autonomous management module of the anchor node: according to the empirical model, i.e., when the system needs to make a large change to solicit all nodes (including the common node and the anchor node) to agree, the anchor node can quickly make a summary through the empirical model to increase the speed. Before this, authentication and authority of the anchor node needs to be set. The empirical judgment algorithm of the anchor node is as follows:
1) An authentication module: and after the anchor node is determined, the address is broadcast to each common node, and each common node gives the authority of the anchor node through a corresponding consensus algorithm.
2) A judging module: and (3) carrying out transaction by the common nodes, recording transaction behaviors of the common nodes by the anchor nodes, voting whether the common nodes agree to the decision or not after a manager makes a decision (the nodes can make the transaction behaviors according to the decision of the manager), and recording the voting result in the empirical model by the anchor nodes. When the administrator makes a decision again, the anchor node makes a judgment according to the data in the empirical model, and each transaction node approves the judgment made by the anchor node by default.
The method has the advantages that the anchor node can rapidly summarize and summarize the judgment of each branch node by recording the previous decision, thereby improving the high transaction performance in the block chain, improving the decision rate, accelerating the system upgrading and changing iteration rate in the block chain, having complete block chain model and more reliable result.
(4) Anchor nodes on the side chains: the generation process of the anchor nodes on the side chain is similar to that of the main chain, the side chain is a complete and independent system, the aim of encrypting currency and finance ecology is achieved in a fusion mode, the anchor nodes and the main chain share the same data, and in order to guarantee the safety in the data exchange process, the anchor nodes on the main side chain are connected to enable the anchor nodes to independently and freely communicate, so that the problem of fraudulent transfer can be prevented.
