All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

Referring to fig. 1, an embodiment of the present application provides a method for determining a verification node in a blockchain, including:

s101: at least part of the block chain link points in the block chain system generate dices in real time based on the set dice model and broadcast in the block chain system;

optionally, in this embodiment, the blockchain system may be a federation chain, a private chain, or a public chain; alternatively, in this embodiment, the block link points may be a block chain light node and a block chain full node. The block chain whole node is a node which possesses all transaction data of the whole network, and the block chain light node is a node which only possesses the transaction data related to the light node.

Optionally, in this embodiment, the block chain node points of the generated dice may also be the block chain node points of the dice received from the other block chain node points.

Optionally, in this embodiment, a monitoring module is disposed on each block chain node, and the monitoring module is configured to monitor whether there is a dice broadcasted in the block chain system, and if there is a dice broadcasted in the block chain system, receive the dice broadcasted;

optionally, in this embodiment, the monitoring module is provided with a monitoring policy, such as timing or monitoring only dice in a fixed format, where it is to be noted that the monitoring modules on all the block link points in the block chain system have the same monitoring mechanism, and the monitoring mechanism corresponds to parameters of the dice model, such as a generation algorithm, a generation time, and the like.

Optionally, in this embodiment, the faces of the dice generated by the dice model in real time may be generated simultaneously, or only one face may be generated each time, and a plurality of faces may be generated continuously.

Optionally, in this embodiment, the faces of the dice may be set, and the dice model may be flexibly set according to the requirements of the application scenario.

Optionally, the shape of the die may also be configured by a die model, such as if the faces are generated simultaneously, the die model includes a plurality of die sub-models, each die sub-model being responsible for generating one of the faces, and a particular die sub-model may be configured in the shape of the die.

Optionally, when the dice model (including the dice sub-model) generates a face of the dice, log data of a system start process of the block chain node and running log data of an application program after the system start are used as input;

optionally, in this embodiment, when each face of the generated dice is broadcasted inside the blockchain system, the faces may be based on TCP (Transmission Control Protocol), UDP (User Datagram Protocol), coap (Constrained Application Protocol), mqtt (Message Queuing telemeasuring Transport Protocol), mqttn (Message Queuing telemeasuring Transport-Sensor network, Message Queuing telemeasuring Transport Protocol Sensor version);

optionally, in this embodiment, the block chain nodes in the block chain system may be grouped, so that each block chain node exists in at least two groups, the block chain node performs broadcast polling on the group where the block chain node is located, and after receiving the dice, the other block chain nodes in the group perform broadcast of the dice in another group where the other block chain nodes are located, thereby achieving fast broadcast of the dice, and being capable of quickly determining whether each face of the dice is uniform, further, speeding up the verification efficiency that the block chain node generating the dice is credible, and ensuring efficient cooperative work of the whole block chain system.

Optionally, in an embodiment, one face of the dice is generated in each time period or at a certain time, so that multiple faces can be generated in multiple time periods or multiple times, and the generation of the control faces in the time-division manner avoids the generation of the faces from being too concentrated, so that the impact of a network storm on the blockchain system can be avoided, and the safe operation of the blockchain system is ensured.

Optionally, in this embodiment, the time or the period of generating the surface may be flexibly configured according to the application scenario.

Optionally, in a specific embodiment, the dice model is a normal distribution function;

S102: the block chain node points of the dice are received to judge whether all sides of the dice are uniform, and if so, the block chain node points of the dice are confirmed to be credible.

Optionally, in this embodiment, if the faces of the die are uniform, it indicates that the state of the block chain node generating the die is stable, and thus it is determined to be authentic.

Optionally, in this embodiment, the faces of the dice are uniform, i.e. the faces are not substantially different, or are identical, but in practice, it is preferred that the faces are not substantially different.

Optionally, in this embodiment, the confidence of the block chain node has timeliness, for example, the block chain node for generating the dice is determined to be trustworthy at a certain time, which only indicates that the block chain node is trustworthy at the time and does not indicate that the block chain node is always trustworthy; therefore, by means of the scheme of the embodiment of the application, for any block chain node, the steps are repeated until a dice with uniform faces is found, so that the block chain node is proved to be credible at a certain moment. Therefore, in other words, the technical scheme of the embodiment of the application is also equivalent to a detection scheme of the block connection point trusted state, so that the real-time detection of the block link point trusted state is effectively realized, and an important basis is provided for the block link point to participate in subsequent accounting, consensus and the like;

The master node is typically always online and provides much more memory than a regular node.

Optionally, in this embodiment, when determining whether each interview is uniform based on the probability model, the probability model outputs a probability that each face is uniform, and the probability is larger, which proves that each face is likely to be uniform, where in order to quickly and effectively determine whether each face is uniform, a probability threshold or a probability range is set, if the probability output by the probability model is larger than the probability threshold or is within the probability range, each face is determined to be uniform, otherwise, each face is determined to be non-uniform, so that the block link points regenerate the faces of the dice, and through a probability-based manner, a situation that the state of the block link nodes in the block link system is changeable and actually credible can be effectively dealt with.

Optionally, in a specific embodiment, the probabilistic model has a uniform prior probability and an optimal probability for each face of the die; the block chain node points of the received dice judge whether all faces of the dice are uniform or not based on a set probability model, and the method comprises the following steps: and judging whether each face of the dice is uniform or not based on the set probability model, the prior probability and the optimal probability after receiving the block chain link points of the dice.

Optionally, in this embodiment, the prior probability and the optimal probability may be obtained based on sample learning.

Optionally, in this embodiment, after obtaining the uniform probability of each face of the dice, the probability, the prior probability and the optimal probability are introduced into a bayesian function, a logical probability is calculated, and whether each face of the dice is uniform is determined according to the size of the probability, where the larger the logical probability is, the larger the probability that each face of the dice is uniform is. Specifically, a logical probability threshold or a logical probability range may be set, if the logical probability threshold is greater than the logical probability threshold or is within the logical probability range, the faces of the dice are determined to be uniform, otherwise, the faces are determined to be non-uniform, and further, the faces of the dice are regenerated by the block link points.
