When we talk about probability (randomness), we show that we are speaking from a position of not knowing. For example. When one flips a coin, what are the odds it will land heads, and what are the odds it will land tails? Over time, with many tosses of the coin, we find that the answer is very close to 50% both ways.
Why don't we know ahead of time what the result will be each time? Because we are unable to measure all the forces acting on the coin sufficiently well to make an absolute prediction. Now, I understand that there are some few people who have practiced so much that they can tell the outcome almost every time. But the point that I am making is, there is no easy way to measure all the forces acting on the coin so that we can predict accurately.
This is what OUR random is. It really isn't random. What it is, is our weakness in knowing, our inability to observe. In the case of the flipped coin, it is our weakness in knowing all the forces acting on the coin.
Essentially, there is NO pure random.
Combined with Chaos Theory, from later last century, determinism can't even be considered globally on a macroscopic scale.
And it should be common knowledge, especially someone interested in cryptography and Bitcoin should know where true random exists and where not.
Everything in nature acts according to the action and reaction principle... cause and effect. Science has no evidence of anything that happens by accident, randomly; everything that we call random activity exists ONLY because we are so extremely limited in our methods of observation, that we can't track the billions upon billions of action-reaction operations in the universe around us.
Is there mathematics that shows the existence of pure random activity? If there is, it lies in realms of quantum mechanics where other math shows that pure random does NOT exist.
A good pool player might be able to hit the cue ball with such precision that it hits a second ball that hits a third ball that taps a fourth ball into a corner pocket.
The God of the Christians hit some "cue balls" way back 6,000 to 25,000 years ago that knocked this whole fantastic universe into place today. Look around yourself at nature, at life, at human emotion, and imagine how great Someone has to be to hit the "cue balls" of the Beginning so that we wind up with all the marvels that we have today.
And if the God of the Christians is great, THE GOD OF MODERN SCIENCE IS FAR GREATER! Why? Because there are COUNTLESS more action-reaction/cause-effect happenings over 13 to 14 billion years than over 6,000 to 25,000 years. And the Big Bang(?) God shot was SOOOOO exceedingly good that it STILL produced what we have today, all the marvels of nature, and the universe, and life, and emotion in people, and human thought, and even scientific investigation by man, even though it had countless MORE numbers of action-reaction, cause-effect activities that the gods of any of the religions.
..Ouch. Young-earth-creationist? Please stop insulting the vast majority of Christians and their intelligence, by calling this small god of yours the "God of the Christians"! Catholics, Lutherans, Orthodox, these churches don't show the willful obscurantism, the weird insistence of a god that, as you pointed out so well, would be an awfully small god, a god that is much smaller than the universe we can see. The medieval bishop who counted and extrapolated some years in the Bible to get your estimation was likely no small mind, he worked with the little he had in his system of reference, without knowing of contrarian evidence. Then scientists, these great minds, watched the earth and her geology, the stars and the universe. Some had religions, others not, but they opened their eyes and saw an earth that was vastly older, a universe far greater than they had imagined.
And then later came some small minds, who were scared by greatness, scared by anything that could be larger than them. They shut their eyes and created fundamentalism, started cults in which they forbade their adherents to use their eyes and minds. You can simply count the years of tree rings for far longer than any date of their "flood", count the years of the strata in ice cores far longer than your "absolute maximum" age. Why do you want to believe in a god that is that small, that you are forbidden to even count, much less look at the stars, for fear that you could cross some arbitrary limits made by very small minds?
