Chapter 195: The Secret of Foreknowledge [3]

"I was just thinking... If you or His Majesty the Dragon King interfere with the growth of this Heavenly Devil King, causing a fundamental difference between her in the future and her now - for example, her in the future does not agree with her now..."

"This kind of thing is hard to happen." His Majesty the Demon King asserted: "Maybe you can exert influence, but her own mind is always the most important - external things are difficult to change."

"But in theory it can still be changed, right?" Wang Qi said: "You will feel tired at this level, right?"

The Demon King looked disappointed: "Yes... This question..."

He paused, then asked: "Do you believe in destiny?"

Wang Qi said: "I was determined not to believe it at first, but since I saw the goddess of beauty, it doesn't matter whether I believe it or not - the so-called "destiny" is also It's just a vague concept created in natural language. We can only see a group of elements in a limited set. "

The Demon King held his forehead: "Sorry, it's my fault, I shouldn't talk to you like this... Let's put it this way. There was a young man who didn't believe in destiny - he didn't believe that there was a destiny in the dark that dominated him. If this destiny is the will of man, then let this person go to hell. If this destiny is the will of heaven, then let this heaven change its appearance. "

"But it was a long time later that he realized that this will of heaven was actually his own will. It was not another self that he didn't recognize, but a whole of his past, future and present. This is his will of heaven. "

The Demon King spread his hands and looked at it: "Our consciousness has always been in chronological order. Or... …In your words, the direction of entropy, the direction of the expansion of the universe, and the direction of time in the heart are exactly the same. The self we know, no matter whose self it is, can only flow in the direction of time, right? But the moment the past and the future merge into one, the essence of our life has already exceeded the time sequence. Self-consciousness itself cannot control it. We naturally become part of the subconscious of a huge creature. "

"If you don't think about this problem, you won't even notice its existence - just like mortals can live without thinking about the topic of "I am me". We don't need to think about this thing, we just need to enjoy the power brought by the future and the past. "

"But sometimes I also think... Have we cultivated ourselves into God's will? Then, we What is this humble self of mine now in front of the Heavenly Saint who designed the Nascent Soul Method? "

Wang Qi automatically filtered out the sadness of His Majesty the Demon King and thought: "That is to say, if a self in the distant future wants to convey spiritual resonance to the self in the past, then it must be recognized by all the selves in the middle? Every minute and every second is necessary?"

"That is also a problem." The Demon King also thought: "Although I personally feel that the self in the distant future has a greater advantage in intelligence, perhaps with a greater weight... and this reverse time process is also very difficult, but in the final analysis, this is an instinctive process."

People do not need to understand the cell membrane ion channel, the heart will beat naturally, and they do not need to understand the central law to know how to reproduce naturally.

This process does not require knowing the principle or the details of the process.

In fact, the instinct of the past and the future returning to one body also works in this way.

No need to know the principle or the process.

You don't even need to know how to make a decision.

The final result will inevitably lead to a decision that you can accept.

Because it must be a decision made by yourself.

The Heavenly Demon King of Rescue doesn't care about life or death - she doesn't care about her own life at all times, so she can't see the signs of her own death.

This is also asking for benevolence and getting benevolence.

Wang Qi couldn't help but think about it.

"Could it be that... there is also a consensus algorithm problem here?"

In other words, the strong man who has the past and the future in one body may contain a consensus mechanism in his body.

The consensus algorithm starts with an "unsolvable two generals problem".

Two generals are attacking the same enemy. General A is considered the commander-in-chief, and General B is the deputy commander. Each general's army cannot successfully defeat the enemy army by its own strength, so they need to cooperate and attack at the same time. This seems to be a simple situation, but there is one thing to note:

In order for the two armies to communicate and decide the time of battle, General A must send a messenger through the enemy's camp to tell General B the time of attack. However, the messenger may be caught by the enemy and the information cannot be transmitted to the friendly army. That will result in General B and his army staying in place when General A launches the attack.

Even if the first message arrives, General B needs to confirm that he received the message, so he has to send a messenger back, thus repeating the situation where the previous messenger may be caught. This situation will extend to infinity, and the two generals will not be able to reach an agreement.

There is no way to guarantee the second requirement, that is, each general must ensure that the other agrees to the attack plan. Both generals will always doubt whether their last messenger will arrive.

- Because the probability that the messenger cannot arrive is always greater than 0, the generals can never reach a consensus with 100% confidence.

On Earth, this problem is called the "Byzantine Generals Problem".

And the Byzantine Generals Problem has an upgraded version called the "Two Army Problem".

In the "two-army problem", two or more generals need to agree on the time to attack their common enemy. The scary thing is that one or more of the generals may be traitors, which means they can lie about their choices.

After a series of detailed arguments, mathematicians came to a conclusion.

When the number of traitors is less than one-third, the algorithm can reach a consensus.

This is the core of blockchain technology.

It does not need a center, nor does it need a "headquarters" to command all the generals. It only takes more than two-thirds of the members to approve an instruction for the entire system to reach a consensus.

It is precisely because of this that blockchain is difficult to invade - it is not afraid of internal traitors. The rebellion of any node is irrelevant. And the cost of hijacking more than one-third of the nodes will be too high.

Idealists see it as a means to fight tyranny and centralization, and criminals see it as a lawless zone.

Could it be that if more than two-thirds of the "self" recognize a certain future flowing into the past, then the current node self does not recognize it and can only accept it?

For a moment, I couldn't figure it out.

So, Wang Qi asked the next question: "So, Your Majesty the Demon King, what does the battle of the foreknowers look like?"

He knew how to seize this opportunity.

His Majesty the Dragon King has always been a secrecy advocate. He may not want the history he chooses to limit the human race to the history he knows, but expects the human race to bring changes that he does not know.

But he asked Wang Qi to fight against the Devil King of Rescue, who is a foreknower. Can it be considered that... His Majesty the Dragon King has tacitly allowed this to happen?

Of course, Wang Qi would never go directly to the Dragon King to confirm this. At least not before meeting the Dragon King.

He would use this opportunity to ask the Demon King a few questions.

The Demon King asked back: "What do you think it looks like?"

Wang Qi thought for a moment: "Complete information dynamic game?"

A complete game means that during the game, each participant has accurate information about the characteristics, strategy space and benefit function of other participants. An incomplete information game means that at least one participant does not have accurate information about other participants, or does not have accurate information about the characteristics, strategy space and benefit function of all participants.

Static game refers to a game in which the participants choose at the same time or not at the same time, but the later actor does not know what specific action the first actor has taken; dynamic game refers to a game in which the participants' actions have a sequence, and the later actor can observe the action chosen by the first actor.

Because of this, games can be divided into: static game with complete information, dynamic game with complete information, static game with incomplete information, and dynamic game with incomplete information.

Dynamic game with complete information is like playing chess. Both sides know all the information on the chessboard - of course, only for Go and Gobang.

The dark chess and flip chess playing methods of military chess are all dynamic games with incomplete information.

The battles of the foreknowers may be like this. Their battles are not only in the present, but also in the past and in the future. In their view, these battles may even happen at the same time.

The ability to foreknow does not look at distance or time, but only at cause and effect.

Perhaps when two foreknowers decide to play against each other, or even as long as they are likely to be hostile, they will start fighting.

For the foreknowers, the universe is just a chessboard. All factors - even the past and future self, are chess pieces.

The Demon King nodded: "Very... vivid metaphor. How did you come up with it?"

"You just said that saving the Heavenly Demon King might be a game with the Demon Emperor, and mistakenly thought that liberating the Demon Emperor would be able to do something." Wang Qi said: "That's it... I just imagined it."

"So, it can't be said to be wrong." The Demon King shook his head: "But I thought about it carefully. If my life is really similar to what you described, then I'd better erase my spiritual wisdom and create a 'future in which I don't exist'."

"First of all, limited foreknowledge is ultimately 'limited'. I can't know too many things, I can only know the information I care about, and it's often just a few words. This even has to be realized in the foreseeable future. Sometimes, it is even only a little better than 'wisdom insight'."

"Secondly, as I said just now, sometimes, the game is not necessarily what we call 'self'."
