Detailed description of the invention
Being described principle and the feature of the present invention below in conjunction with accompanying drawing, example is served only for explaining the present invention, and
Non-for limiting the scope of the present invention.
Embodiment one, the write authority distributing method of a kind of block chain.Method the present embodiment provided below in conjunction with Fig. 1
It is described in detail.
See Fig. 1, S101, record multiple terminal solve according to preset algorithm rule generate a difficult problem spent calculating time
Between.
Concrete, record multiple terminal and solve the difficult problem according to the generation of preset algorithm rule respectively and obtain result of calculation institute
The calculating time spent, wherein, described preset algorithm rule specifically includes POW (Proof of Work, proof of work) algorithm
And POS (Proof of Stake, rights and interests prove) algorithm, described POW algorithm specifically includes bit coin algorithm, Lay spy's coin algorithm
And X11 algorithm, described POS algorithm specifically includes a some coin algorithm and ether mill algorithm.It addition, the calculating of each terminal is
A same difficult problem.
S102, is carried out ascending sort the calculating time that each terminal is corresponding, and by the calculating time less than Preset Time pair
The multiple terminals alternately terminal answered.
Concrete, each terminal solves the time difference that a described difficult problem spends, and enters the calculating time that each terminal is corresponding
Row ascending sort, and set a Preset Time, the time alternately terminal of the terminal within described Preset Time will be calculated,
Remaining calculating time is left out more than the terminal of described Preset Time, such as, is set to by Preset Time 1 minute, then at meter
Evaluation time terminal outside 1 minute is all not eligible for alternately terminal, only calculates the time terminal less than 1 minute qualified
Alternately terminal.
S103, select from described alternative terminal according to default access rule terminal as write terminal, will be to district
The write authority writing data in block chain data base distributes to said write terminal.
Concrete, according to default access rule select from described alternative terminal a terminal as write terminal, will be to
The write authority writing data in block chain data base distributes to said write terminal, described default access rule specifically include with
Machine allocation rule or efficiency allocation rule.
When described default access rule is random assortment rule, described regular from described alternative terminal according to default access
One terminal of middle selection specifically includes as write terminal: randomly select a terminal from described alternative terminal, as
Write terminal, the probability that in described alternative terminal, each terminal is selected is identical.Such as, if a total of five terminals, A terminal
The calculating time that the calculating time is 5s, D terminal that the calculating time is 2s, C terminal that the calculating time is 1s, B terminal be 10s, E
The calculating time of terminal is 20s, if Preset Time is set to 15s, then tetra-terminals of A, B, C, D become alternative terminal, each end
The selected probability becoming said write terminal is held to be 1/4.
When described default access rule is efficiency allocation rule, described regular from described alternative terminal according to default access
One terminal of middle selection specifically includes as write terminal: according to formula (1) computational efficiency parameter, then join according to described efficiency
Number is calculated each alternative terminal and is selected to the probability of said write terminal, and according to described probability from described alternative end
In end, one terminal of selection is as write terminal, described formula (1) is as follows:
Wherein, tiFor the calculating time that each alternative terminal is corresponding, d is efficiency parameters,For the alternative terminal of i-th
It is selected to the probability of said write terminal.The probability that calculating time the shortest terminal is selected to write terminal is the highest.
Such as, if a total of five terminal, when the calculating time of A terminal would be the calculating that the calculating time of 1s, B terminal is 2s, C terminal
Between be calculating time that the calculating time is 10s, E terminal of 5s, D terminal be 20s, if Preset Time is set to 15s, then A, B, C,
Tetra-terminals of D become alternative terminal, are 5/9 according to the value that formula (1) is calculated as efficiency parameters d, and respectively obtain A, B,
The selected probability becoming write terminal of tetra-terminals of C, D is respectively 10/18, and 5/18,2/18,1/18, thus the time of calculating is more
Short terminal is selected, and to become the probability of write terminal higher.
Embodiment two, the write right assignment system of a kind of block chain.System the present embodiment provided below in conjunction with Fig. 2
It is described in detail.
Seeing Fig. 2, the write right assignment system of a kind of block chain that the present invention provides includes recording unit, sequence determines
Unit and authority allocation unit.
Record unit, for record multiple terminal solve according to preset algorithm rule generate a difficult problem spent calculating time
Between.
Concrete, described preset algorithm rule specifically include POW (Proof of Work, proof of work) algorithm and
POS (Proof of Stake, rights and interests prove) algorithm, described POW algorithm specifically include bit coin algorithm, Lay spy's coin algorithm and
X11 algorithm, described POS algorithm specifically includes a some coin algorithm and ether mill algorithm.
Sequence determines unit, and for the calculating time that each terminal is corresponding is carried out ascending sort, and it is little to calculate the time
In multiple terminals alternately terminal that Preset Time is corresponding.
Authority allocation unit, for selecting a terminal as write according to default access rule from described alternative terminal
Terminal, distributes to said write terminal by the write authority writing data in block chain data base.
Concrete, default access rule described in described authority allocation unit specifically includes random assortment rule or efficiency
Allocation rule.
When described default access rule is random assortment rule, described authority allocation unit is specifically for from described alternative
Terminal randomly selects a terminal, as write terminal, the probability phase that in described alternative terminal, each terminal is selected
With.
When described default access rule is efficiency allocation rule, described authority allocation unit is specifically for according to formulaCalculate efficiency parameters, be then calculated according to described efficiency parameters
Each alternative terminal is selected to the probability of said write terminal, and selects one from described alternative terminal according to described probability
Individual terminal is as write terminal, wherein, tiFor the calculating time that each alternative terminal is corresponding, d is efficiency parameters,It is i-th
Individual alternative terminal is selected to the probability of said write terminal.Calculating time the shortest terminal is selected to write terminal
Probability is the highest.
The write authority distributing method of a kind of block chain that the present invention provides and system, it is possible to record and add up each terminal
Calculate a difficult problem the calculating time, and filter out from multiple terminals the calculating time less than Preset Time multiple terminals alternately
Terminal, then according to default access rule selects a terminal as write terminal from alternative terminal, gives its write authority.
The present invention selects write terminal according to default access rule and gives write authority rather than give the calculating time by write authority
The shortest terminal, solves write authority and concentrates on " stay away from work without leave " potential safety hazard of the block chain data base caused in hands of minority and ask
Topic, improves the safety of block chain data base, and practicality is stronger.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
