Embodiment
Referring to Fig. 1, Fig. 1 is the method flow diagram of the common recognition method of block chain in an embodiment.
In the present embodiment, the common recognition method of the block chain comprises the following steps：
S101, obtain the common recognition problem that current block proposes.
Block chain is made up of multiple blocks, and each block corresponds to unique cryptographic Hash, passes through Hash between block and block
Value forms mutual relevance, and the cryptographic Hash can be understood as the identity of block.
In publicly-owned block chain, any personal or group can participate in common recognition process, and new area is established on block chain
Block.But in the same time, an object can only be selected to establish this block, in general, one is provided altogether by current block
Knowledge problem, participant, that is, ore deposit person is dug, who first answers this common recognition problem, it is possible to obtain the right for establishing next block, that is, dig
Ore deposit success.
S102, the common recognition problem is answered, during the answer of the common recognition problem, the result of next step depends on
The output of previous step.
In publicly-owned block chain, because participant is numerous, digging ore deposit competition is very fierce, and the present embodiment is set common recognition problem
Put, the common recognition problem can only be calculated by single line bar algorithm, during calculating, the result of calculation of each step is all
Output depending on previous step.
The single line bar algorithm can not be calculated by parallel mode, it is not necessary to such as parallel by the computing device of costliness
Processor, distinctive digging ore deposit chip, or multiple FPGA (Field-Programmable GateArray, field programmable gate
Array) etc. handle this calculating process.Ore deposit process, which will be dug, becomes simple, reduces competitors during common recognition to dig
Ore deposit success and caused by resource consumption, such as calculate the huge consumption of energy, the consumption of the energy, the consumption of hardware device, produce this
Consumption of human resources etc., reduces the operation cost of block chain, while inhibit harmful competition during a little hardware devices.
S103, the qualification for establishing next block is obtained according to the result of answer.
The authority for establishing next block can be obtained by first answering the participant of common recognition problem.
The common recognition method of above-mentioned block chain, the common recognition problem that current block proposes is obtained, the common recognition problem is answered, in institute
During the answer for stating common recognition problem, the result of next step depends on the output of previous step, is obtained according to the result of answer
Establish the qualification of next block；This method carries out the calculating of common recognition problem using single line bar algorithm, each during calculating
The result of calculation of step both depends on the output of previous step, it is impossible to using parallel processing manner, simplifies common recognition process, reduces area
The operation cost of block chain, while inhibit harmful competition.

In the present embodiment, the common recognition method of the block chain comprises the following steps：
S201, the cryptographic Hash of current block is obtained, the relevance with the current block is established according to the cryptographic Hash.
During common recognition, it is necessary to first pass through block before participant establishes new block on the basis of current block
Unique cryptographic Hash finds the current block, and establishes the relevance with current block.
S202, obtain the common recognition problem that current block proposes.
S203, the common recognition problem is answered according to Chaos iteration algorithm, it is next during the answer of the common recognition problem
The result of step depends on the output of previous step.
During the answer of the common recognition problem, the result of next step depends on the output of previous step.Chaos iteration is calculated
Method is a kind of single line bar algorithm, when answering the common recognition problem according to Chaos iteration algorithm, it is impossible to by multiple terminal parallel computations,
The harmful competition during block chain common recognition is inhibited, has saved human resources.
S204, the terminal answered at first is chosen as the object for establishing next block according to the result of answer.
In publicly-owned block chain, multiple terminals simultaneously participate in common recognition process, and a terminal can be considered as a participant, often
Individual terminal discloses each other during the common recognition problem is answered, and information sharing, will be solved at first automatically after common recognition process terminates
The terminal for answering out common recognition problem is chosen for the lower object for establishing next block.
In addition, when each terminal can also set the desired value of duration needed for answer common recognition problem according to demand not less than presetting
It is long.
S205, establish next block.
The common recognition method of above-mentioned block chain, the common recognition problem that current block proposes is obtained, according to the chaos iteration of single line bar
Algorithm answers the common recognition problem, and the result of calculation of each step both depends on the output of previous step, it is impossible to using parallel processing manner,
Common recognition process is simplified, reduces the operation cost of block chain, while inhibits harmful competition.
In addition, the embodiment of the present application also provides a kind of computer-processing equipment, the computer-processing equipment includes memory
And processor, the memory storage have the computer program for the common recognition method for realizing above-mentioned block chain, the processor is used to hold
The row computer program.
Due to solving the problems, such as that the algorithm of common recognition is single line bar algorithm, calculating process is simple so that realizes the calculating of this method
Machine program can be run on common computer equipment, such as X 86 processor, X64 processors, be not limited to both processing
Device.For these processors than more conventional, price is cheap compared with parallel processor, reduces the operation cost of block chain.
