"The technologies that will have the greatest impact on the coming decades have already emerged. It's not social media, it's not big data, it's not robots, it's not even artificial intelligence. You may be surprised to hear the answer, which is the underlying technology of digital currencies like Bitcoin - blockchain. ”

This is what speaker Don Tapscott said in the TED section of the NetEase Open Class. Through this speech, people will understand the impact of data blockchain on money, business, government and society.

After all, Ji Zhen has been to the technology world further, so he has full confidence in the application of blockchain.

Indeed, blockchain has a very strong future.

The application of blockchain can protect property rights and prevent piracy through immutable timestamp records; It can also ensure that content creators get paid more, rather than going through all kinds of exploitation by middlemen.

Even, to solve the privacy impact of big data on people.

In foreign countries, people attach great importance to their privacy. However, in China, due to the vigorous development of various Internet companies in China, it has brought a lot of convenience to the country and the people.

The material needs of most people are satisfied, and people have not paid too much attention to their privacy before their material needs are saturated.

However, the killing of Internet companies has set off a little bit of signs.

Big data, which collects online data of individuals and uses this data to create a virtual person. The key is that this virtual person is not in his own hands, but in the hands of Internet companies.

This is the essence of Internet companies using personal data privacy to do business.

However, blockchain technology can really solve this problem and protect people's privacy.

Once blockchain technology is popularized, the impact on society is absolutely in all aspects, such as commercial intermediaries, Internet data vendors, etc.

And most importantly, blockchain uses virtual currency. And when it comes to currency, it's not that simple.

This is evident in the ban of Bitcoin in China.

However, the development of blockchain will take some time.

Now all kinds of YY on the network, all kinds of imagination of the future. However, it seems too empty.

Now the underlying technology and infrastructure are not mature enough, giving many people a kind of, although it is not clear whether the technology of blockchain can really be used as the cornerstone of value interconnection in the future and change the world like the Internet.

But if you don't do anything, you feel like you're missing out on a big opportunity.

This anxiety can be easily generated.

Blockchain involves cryptographic algorithms, P2P networks, scripting languages, and more. There are not many people who study this kind of underlying infrastructure, and even the link layer is not mature, and most people go to the application layer to conceive various applications.

Although there is also a driving force, or to improve enthusiasm, but also make the underlying technology researchers feel impetuous, and there are not many people who really do to get through this, in addition to the difficulty, high investment, it is not a large company is basically difficult to complete independently, and now there are many speculators.

Cryptographic algorithms are an important part of the blockchain architecture.

However, Ji Zhen is also a mathematician, and he wants to solve the NP complete problem, that is, NP=P? The question is whether NP is equal to P or NP is not equal to P.

This mathematical puzzle is regarded as one of the most prominent problems in logic and computer science.

The fact that NP Perfection topped the Millennium Puzzle Million Dollar Award is a testament to his prominence and charisma.

Whether it is NP=P or NP≠P, both will have a shocking impact on cryptography.

If P = NP is proved, the security (including financial intelligence) is based on these assumptions: the decomposition of large prime numbers, the decryption of DES (the Data Encryption Standard), which cannot be solved quickly with a digital computer.

If P≠NP is proved, then the decomposition of large prime numbers is still not NPC's? It is more difficult to prove the security of cryptography such as RSA and DES than to prove P1NP.

Not only is the cryptography based on discrete quantities affected by the "P vs. NP" problem, but also the cryptography based on continuous quantities is also affected by the "P vs. NP" problem on the real number loop.

It can be said that the NP complete problem is definitely a tsunami for cryptography.

Even if the NP problem is substantively solved, the digital information of the whole world will be turned upside down!

Not to mention blockchain.

However, even if Ji Zhen solves the complete problem of NP, it is still far away. Blockchain can continue to develop for decades for the time being.

At that time, it is difficult to say which direction of science and technology will develop.

"However, the blockchain stall is so big! I just want to do research comfortably, and I don't want to pay attention to that big stall, people can be busy to death. ”

Look at Wang Jianlin and Jack Ma's father, although they do have money. But when it comes to their realm, money is just a number and doesn't bring them much happiness.

On the contrary, they also have to bear great responsibility, and behind them, there is a large group of people counting on them.

The daily schedule is full. Ji Zhen doesn't want this kind of life at all.

Ji Zhen looked at Xu Linfei and didn't know whether the blockchain should be handed over to her.

Blockchain can achieve the myth of wealth and the myth of the Internet, which Ji Zhen has no doubt.

However, are these really important to Ji Zhen's entire family? Is it really needed?

···

"I've got an idea." Xu Linfei held her chopsticks and said. Then I saw that my husband's expression was very puzzled, and then said, "I already have an idea for the first variety show I produced." ”

"Oh? Tell me about it. Ji Zhen shifted his attention from the blockchain to Xu Linfei's variety show.

"Singing shows? Indoor talk show? Crosstalk sketches? Blind date life? Emotional counseling? Or is it a reality show? ”

Ji Zhen threw out the type of variety show he knew in a row.

"Reality TV!"

Xu Linfei's chopsticks slapped on the table with a snap, and she said these three words loudly.

"What kind of reality show?" Ji Zhen asked again.

There are also many kinds of reality shows, including reality shows that run restaurants and inns, reality shows that tear off famous brands and run, and reality shows that decipher reasoning, and there are various types.

Xu Linfei looked at Ji Zhen, her eyes lit up, "I want to do an adventure survival show!" ”

Ji Zhen was really surprised by Xu Linfei's idea. At present, all small and fresh programs focus on healing, and a series of slow variety shows such as "Dear Inn", "Youth Hostel", "Beautiful House", "Longing for Life" and so on dominate the screen.

Although there are also outdoor competitive reality shows represented by "Run, Brother", "Extreme Challenge", "High Energy Youth League" and so on.

However, on the whole, slow variety shows are showing an upward trend.

At this time, Xu Linfei actually wants to come to an adventure survival show?
