Statistical test

GINAR is a blockchain technology company specializing in providing a decentralized random number generator. Random Number Generation, or RNG, is a key component to applications that benefit from true randomness. GINAR is set to release a best-in-class decentralized.

  • Random Number Generator (dRNG) that will change the financial, gambling, online gaming, and IOT industry by providing the fastest, most secure and easily verifiable service, ..

  • For more detail about GINAR: Read our white-paper ->

This is result of Dieharder statistical test suite for Random Number Generator (RNG) that apply to GINAR RNG

Diehard Statistical Test Suite

Diehard tests are a battery of statistical tests for measuring the quality of a random number generator. It contains 16 statistical tests. This battery was developed by George Marsaglia over several years and first published in 1995. It is a complete, thorough and comprehensive set of statistical tests for PRNG. This set of statistical tests serves as some kind of litmus for checking and eventual certification of PRNG. If a PRNG passes Diehard statistical tests, then it can be used in more serious scientific researches.

Diehard Statistical Test Suite

Installation

  • You can install dieharder test suite directly from Linux Package Managesment. (Ubuntu)
$ sudo apt-get install dieharder
  • Or you can clone our repository and build the Diehard Test by yourself using our C source code (using Makefile)

Get data for random test

You need a dataset of random number for the test. We have built a function that help you get data from GINAR:

  • Login your account GINAR
  • Initialize your session key
  • Copy the init-session-key link (url)

(More detail, please visit our documentation website)

This test suite requires a lot of numbers. We recommend using 30.000.000 numbers.

Or you can get the sample of random number that we provide on github.

  • Clone the repository or just download zip file and all extended file (archive.*).
  • unzip the file and you will get input.bin (the random-number-file gotten from GINAR).

Run the test

$ dieharder -d {0-16} -g 202 -f input.bin [-D default -D histogram]

Output and visualization

You can read the result in output2.txt on github or read output of the test suite when you run the command above.
