wherein T is the application time, (n)3+n4) For the total number of alternative words, n3For the total number of alternative tokens passing the validity verification, n4For the total number of alternative words failing the validity verification, t3Tx is the number of concurrences per second, t is the time for invoking said intelligent contracts in turn4Generating a time for a block of the block chain.
Accordingly, the total number of all candidate terms submitted is (n)3+n4) Then, the intelligent contracts are required to be called in sequence for verification and comparison, and then n meeting the requirements is required3The number of the alternative terms needs to call the intelligent contract again to write in the block chain. If the time for calling the intelligent contract is t3And considering the number of concurrency per second as tx and the generation time of the block as t4And obtaining the calculation formula of the application time.
In the data management device provided by the prior art, the alternative words are applied as standard words to be examined by examiners, and the calculation formula of the application time is as follows:
wherein T is application time T1Time taken for examination, n1Number of words used for alternatives, n2For the purpose of the alternative word combing quantity,
integrating the time index function with probability density function of f (t) e-(0.08t-0.08)。
Further, fig. 6 is a schematic diagram of application time when an alternative wording is applied as a standard wording according to a second embodiment of the present invention. As shown in fig. 6, the abscissa corresponding to each point represents the number of alternative words, and the ordinate represents the required application time. Estimated by actual operation, n in two models1、n2、n3And n4All account for the general examination50% of the number of words used for nuclear alternatives, t in the prior art1T in this application is monitored for 1 minute according to the experiment30.012 seconds, and the average time of one block generation is used to obtain t in the present application4The time is 13.55 seconds, when a user applies the same number of alternative words as standard words, the auditing time used by the block chain is obviously shorter than the time used in the prior art, and the time consumption difference between the two is more obvious when the number of the applied alternative words is more; the time efficiency of the invention in the application verification process is obviously superior to that of the prior art.
Therefore, when the alternative word-using application is the standard word-using, the method can effectively shorten the time of the alternative word-using application as the standard word-using, shorten the data processing time of the data platform, improve the efficiency of the data platform, avoid the hidden danger of overlarge authority of the examiner in the manual auditing mode in the prior art, bring convenience for the use of personnel, reduce the burden of the data platform, prolong the operation time of the data platform and facilitate the use of personnel.
