Problems solved by technology

[0002] With the continuous development and application of blockchain technology, stability issues have become increasingly prominent. In the POS and Dpos consensus mechanisms, if there is no abnormal rollback of the block, the share / equity held by the user and the income are positively correlated , if the block rollback is abnormal, it may cause uneven and unfair mining income for users, resulting in the loss of users and the decline of user trust
Due to the decentralized nature of the blockchain network, there is no centralized collection and management tool for blockchain stability detection and anomaly detection, especially for mining revenue calculation and positioning linked to user revenue. challenge

Embodiment 1

[0028] A blockchain anomaly identification method, such as figure 1 As shown, including: S101, obtain the share of the mining address; S102, sort the mining address according to the number of shares; S103, select N mining addresses according to the share within the set window value range, as a mining address group; S104. Calculate the difference ΔP between the maximum share and the minimum share of the mining address in the mining address group; S105. Keep the mining address group whose ΔP is less than the set share reference difference, and discard the mining address group whose ΔP is greater than the set share reference difference. Address group; S106. Sliding the window to obtain the mining address group whose ΔP is less than the set share reference difference.

[0029] N is the set window value. The set window value and the set share reference difference are all empirical values, which are determined by considering the number of nodes in the blockchain network system and t...

Embodiment 2

[0039] A block chain abnormal identification system, according to the above-mentioned a block chain abnormal identification method, a mining address share statistics module, used to select qualified mining address groups according to the above-mentioned method; abnormal mining A mining address group identifying unit, configured to identify abnormal mining address groups according to the method described above. The abnormal mining address group identification unit is also used to check the rollback number of each mining address in the abnormal mining address group, locate the mining address whose rollback number is too large, and complete the positioning of the abnormal mining address.

[0040] The system can exist in the blockchain network in a centralized (similar to existing centralized application software) or decentralized form (such as smart contracts, DAPP, etc.), and is used to detect whether the mining address mining is abnormal or not.

Embodiment 3

[0042] An apparatus comprising: one or more processors; memory for storing one or more programs which, when executed by the one or more processors, cause the One or more processors execute the method as described above.

[0043]A storage medium storing a computer program, when the program is executed by a processor, implements the method described in Embodiment 1 above.

[0044] image 3 It is a schematic structural diagram of a device provided by an embodiment of the present invention.

[0045] Such as image 3 As shown, as another aspect, the present application also provides a device 500, including one or more central processing units (CPU) 501, which can be 508 programs loaded into random access memory (RAM) 503 to execute various appropriate actions and processes. In the RAM 503, various programs and data necessary for the operation of the device 500 are also stored. The CPU 501 , ROM 502 , and RAM 503 are connected to each other via a bus 504 . An input / output (I / O...

Abstract

The invention discloses a blockchain anomaly identification method and system, equipment and a storage medium, and relates to the technical field of blockchains. The method comprises the steps of obtaining a share of a mining address; sorting the mining addresses according to the shares; selecting N mining addresses according to share sorting in a set window value range to serve as a mining address group; calculating the difference delta P between the maximum share and the minimum share of the mining address in the mining address group; reserving the mining address groups of which the delta Pis smaller than the set share reference difference, and abandoning the mining address groups of which the delta P is larger than the set share reference difference; and sliding the window to obtain amining address group of which the delta P is smaller than a set share reference difference. According to the method, whether the current network is stable or not and whether abnormal mining exists ornot can be effectively measured and calculated by collecting the block rollback data of the mining address of the user, accurately positioning the abnormal data through a mathematical method and evaluating the network stability.

Description

technical field [0001] The present invention relates to technical fields such as block chains, and in particular to a block chain abnormality identification method, system, equipment, and storage medium.
