Are bitcoins safe from attackers who use quantum computers?



The fact is this. There is quite a small number of quantum computers in the world. They are easy to control. And there is no free access to those computers. If the quantum computer is in some cave there is the possibility to double-check the code that s driven by using quantum computers. But if some intelligence service uses that quantum computer. There is the possibility. That it will use as a tool for network attacks. 

Trusted organizations are controlling those systems. And that means the internet is safe from private attackers who use quantum computers. But the problem is that some governments might have a will to attack other states' facilities by using quantum computers. 

Nobody protects people against governmental actors. If the hackers are operating under governmental protection. There is no way to get them to the court. 

The NSA is not the only network intelligence organization in the world. Chinese and Russians are also interesting in quantum computers. And those governments have their way to make hackers cooperate with their military and intelligence organizations. If some hacker would not cooperate those governments will make some trouble to that person who dares to deny their offer. 

In the worst cases, some family members will get in trouble. If the hacker says "no". And the offer goes like this. If the hacker will cooperate with authorities, some of that person's family members would not get a new workplace in carbon mining. 

And one area where quantum computers are the ultimate tools is cryptology. Quantum computers can use to break protective algorithms. The thing is that the benefits and power of quantum computers are well-known. That makes them very financed and very wanted tools.

As I wrote earlier, there are not many quantum computers in the world yet. But the situation can change quite soon. The R&D work around quantum computers continues. And the advantages in that area are impressive. The quantum computers would turn more common all the time. 

And sooner or later also medium and small-size companies can buy those systems. So in those companies may work people with some gang-contacts. And they can offer access to their systems for private hackers.

The biggest threat from the non-governmental sector is that some hackers will get access to quantum computers. And they can use the quantum systems for carking tools. When those quantum systems turn more common, there is the possibility that this kind of quantum system would get into the wrong hands.

Could this be the thing, that some people don't want you to know about zombies?

Could this be the thing, that some people don't want you to know about zombies? The simplest way to control zombies, which are made by using tetrodotoxin, which is called "zombie poison" is to use the automatic dispenser, which is normally used in diabetes treatment. In this case, the dispenser would be loaded by using tetrodotoxin. If the level of this poison is right, the person would be totally under the control of other people. And if the system cannot detect this poison there is a possibility to make the laboratory experiment when the staff will follow the decrease of the tetrodotoxin, and then the system can use a simple clock, which will inject poison to the body of a victim after a certain time. This would be an effective tool in the hands of military and counter-terror operators. Those zombies can be captured enemy operators, who will send back, and then they just kill their ex-partners. By using genetically engineered bacteria could be possible to create t...

Terrifying visions of genetic engineering.

 Terrifying visions of genetic engineering.  The modern Hounds of Baskerville ABW:s (Advanced biological weapons are the modern Hounds of Baskerville. The term ABV means the animal which is genetically engineered. And which is controlled by using some interactive electronic systems. There is a possibility to connect the action camera to dogs collars. And transmit commands to that animal by using electronic systems. Spoken words can use to the commands.  Or they can be a series of sounds that are stored in the sound files. When the operator activates a certain file that sound means a certain command to the animals. There is the possibility to automatize some commands by connecting the system to the image recognition tool. When the action camera sees something that is stored in the memory of the computer. That system sends the coded order to the animal.  Nanotechnology and genetic engineering are the most lethal combination in the world. The ABW:s (Advanced Biological ...

The story of (Northrop?) TR3A "Black Manta"

    Image I The story of (Northrop?) TR3A "Black Manta" Sometimes there have been discussions that the mysterious TR3A "Black Manta" was a study project for the B-2 bomber.  That means that TR3A was used as the flying mockup for testing the aerodynamic and control solutions for the B-2 "Spirit" bomber. The thing that supports this thing is that the manufacturer of both planes is Northrop corporation.  Along with "Aurora" was flying one other mysterious aircraft, TR3A "Black Manta". The system is described as the "Stealth VTOL" (Vertical Take-Off and Landing) aircraft. Unless the mysterious TR3B, the Northrop TR3A is the conventional VTOL-aircraft, what is using regular jet engines, but what has the stealth-body.  Image II The thing is that the stealth-reconnaissance aircraft, which uses a similar technology with the Northrop B-2 bomber would be an interesting part of the weapon arsenal. There is a possibility that the TR3A was...
