这段话摘自文章:

局部熵的使用:从外部来源收集数据后，需要在局部生成熵。为此，我们使用了自己的TRNG(真随机数发生器)，这是一种依靠电路上的量子过程产生随机比特的硬件。每分钟，TRNG生成一个512位的值。< / p >

I found the article confusing. They allude to seismic data being used but the quote from the article suggests that the random number is generated using hardware that generates the random number based on quantum mechanical processes.

The article also mentions the use of cryptography. Perhaps the daily seismic data (which is essentially unpredictable), is used as a seed for the cryptography.
