How to carry out Nakamoto sunrika

1.

The concept of bitcoin was founded by Nakamoto

On December 12, 2010, when bitcoin graally became a hot topic, he quietly left and disappeared from the Internet

As a descendant of samurai, Nakamoto was born in 1949 in Beppu, Japan. His mother, quanzi, was a Buddhist and brought him up in poverty

When his parents divorced in 1959, Nakamoto's mother remarried and immigrated to California with her three sons. Nakamoto and his stepfather don't get along well, but according to his younger brother Arthur, Nakamoto showed his talent in mathematics and science when he was very young, but also showed his "fickle and strange interest"

Nakamoto graated from Caltech, majoring in physics. Upon graation, he joined Hughes Aircraft and worked in defense and electronic communications. Later, Nakamoto worked for the U.S. military, and his experience was classified as a state secret. Now searching his files, his life is a blank

In 2008, in an e-mail group discussing information encryption on the Internet, he published an article outlining the basic framework of the bitcoin system. In 2009, he established an open source project for the system, officially announcing the birth of bitcoin. On December 12, 2010, when bitcoin graally became the climate, he quietly left and disappeared from the Internet

2. Nakamoto uses Poisson distribution instead of approximating binomial distribution. Poisson distribution is not only the approximation of binomial distribution, it can also be applied to the situation that binomial distribution can not meet. 51% of the attacks satisfy Poisson distribution but not binomial distribution. Evidence: in the same time, honest computing power calculated z = 10 blocks, while attack computing power calculated k = 15 blocks, K & gt; z. It could happen. The binomial distribution can only calculate K & lt= In the case of Z, we can't calculate K & gt; Z. Conclusion: Nakamoto's calculation is correct. It is this netizen who has mistaken the concept. For example, the binomial distribution is like this: suppose that the probability of British soldiers being kicked to death by horses is fixed at m, and there are 100 British soldiers in a team, how to distribute the number of times s of British soldiers being kicked to death by horses? S may be equal to 0, may be equal to 100, but cannot be greater than 100, because a soldier cannot be kicked to death twice. The Poisson distribution is like this: suppose that the probability of British soldiers being bitten by mosquitoes is fixed at m, and there are 100 British soldiers in a group, how to distribute the number of times s of British soldiers being bitten by mosquitoes? S can be zero, 100, or more, because a soldier can be bitten twice by a mosquito.

3. Wang Xia's words, I think like this, you can directly add from the personal center.

4. Words: Yu Zheng
Song: Tan Xuan
editor: Xu Heli
female: flowers bloom and fall in infinite loneliness
missing is too vast
who is right and who is wrong is just a process
don't be persistent, don't be afraid to delay
follow me well
even if you burn yourself in the fire, you will never be weak

male: I am in my heart in my eyes
I met you
love and hate are just cause and effect
even if it is cause and effect Do not think too much
you accompany me
never go back to
woman: fate is repeated and bumped back and forth,
cling to you and I
hold hands with you and fear to become a bubble
male: repeatedly poking at the heart and coming to the storm
a miss too clinging
: lost the soul, and who said you, I
female: flowers bloom and fall, infinite loneliness,
miss too much. Vast
who's right and who's wrong is only after
don't be persistent, don't be afraid to delay
follow me well
even if you burn yourself in the fire, you will never be weak
man: in my eyes, in my heart
I met you
love and hate are only cause and effect
even if it's a disaster, don't think too much
have you with me
never shrink back even if you are possessed
woman: fate bumps repeatedly
cling to you and I
hold hands with you and fear to become a bubble
male: repeatedly poking at the heart and coming to
a miss too clinging
: lost the soul, and who said you, I
female: too many legends can not hide
trapped you and I
tears can not be removed from the
man: what legend do he deceive
together: in the ice and fire with whom to say you and I
in the ice and fire with whom to say you and I

5. The subversive characteristics of blockchain lie in the following four aspects: first, transparency. The data record of the blockchain system is transparent to the nodes of the whole network, and the update operation of the data record is also transparent to the nodes of the whole network, which is the basis of the trustworthiness of the blockchain system. Because the blockchain system uses open source programs, open rules and high participation, the data records and operation rules of the blockchain can be reviewed and traced by the nodes of the whole network, with high transparency< Second, openness. The blockchain system is open. In addition to the fact that the private information of the parties directly related to the data is always encrypted, the data of the blockchain is open to all (except the blockchain system with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through the open interface, so the information of the whole system is highly transparent< Third, information can not be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for private blockchain systems with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high
Fourth, decentralization. Decentralization is the most basic feature of the blockchain, which means that the blockchain no longer depends on the central processing node and realizes the distributed recording, storage and updating of data. In the traditional centralized network, attacking a central node can destroy the whole system, while in a decentralized blockchain network, attacking a single node cannot control or destroy the whole network. More than 5% of the nodes in the master network are just the beginning of gaining control. 2019 is the first year for the commercial application of blockchain technology, and the stimulation of favorable policies will make the development of blockchain technology more stable
with the application of blockchain technology graally penetrating into many fields such as digital finance and Internet, we have a clearer understanding of the value of blockchain
blockchain has formed a situation of global competition, and all countries are seizing the development opportunities, let alone China; Therefore, there is no doubt that blockchain has become a national strategy.

6. Bitcoin mining: using computer hardware to calculate the location of bitcoin and get the process is called mining

essence of bitcoin: the core of bitcoin lies in the blockchain, and its essence lies in creatively leading to the idea of decentralization and unification. This is the first time in the history of the Internet and even human beings to combine decentralization and unification, which is right for people who believe in bitcoin

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million.
