How did bitcoin start

2. The topic of blockchain and bitcoin has gone crazy recently

in fact, Mr. Xiao Zaojun paid attention to this very early. Last year, I wrote a popular science article about blockchain and bitcoin. At that time, the price of bitcoin seemed to be $3000, and many people suggested that I start. After thinking about it, I still didn't buy it

later, bitcoin soared and plummeted, peaking at $20000, and then quickly fell to $8000. I'm both sorry and glad<

today, I've also rerouted that article (with some revisions). I hope it will help you to know more about blockchain and bitcoin technology

in my opinion, whether you invest in bitcoin or not, whether you believe in blockchain or not, first of all, you should fully understand them

today, let's talk about blockchain and bitcoin

well, here's the thing -

these days, if you haven't heard of bitcoin, it's really out

when you see the glittering gold coin, is it a moment of spirit

in other words, bitcoin is not an ordinary fire nowadays. Some friends always come to ask Mr. Xiao Zaojun about it. Even when you take the subway, you can hear people around you talking about it<

bitcoin has been used for several times, and the most influential one is this:

children's shoes must be familiar, and indivial children's shoes are expected to be shocked

Yes, this is the blackmail window that popped up after computer poisoning when wannacry blackmail virus broke out in May 2017

the words in the blue box are the way blackmailers ask for ransom - "only accept payment in bitcoin", and others are not recognized. At the same time, the blackmailer also kindly tells you how to buy bitcoin

as a result, bitcoin, along with the blackmail virus, swipes the screen all over the world, greatly enhancing its popularity.

Bitcoin, English name bitcoin, is a digital currency based on blockchain technology, which is composed of a series of computer-generated complex codes. Like RMB's ￥ and US dollar's $, bitcoin has its own symbol, the "B" in the figure below

The inventor of

bitcoin is Nakamoto. Satoshi Nakamoto is the creator of bitcoin protocol and its related software bitcoin QT. In 2008, he published a paper called "bitcoin: a peer-to-peer electronic cash system", describing an electronic currency and its algorithm that he called "bitcoin"

In 2009, he released the first bitcoin software and officially launched the bitcoin financial system

In 2010, he graally faded out and handed over the project to other members of the bitcoin community

Nakamoto is believed to hold about one million bitcoins. If the price of each bitcoin was $2W, it was worth $20 billion at one time. So far, his true identity is still unknown to the outside world, that is to say, no one knows who Nakamoto is

bitcoin appeared after the global financial crisis in 2008. In fact, before that, many people have tried electronic currency, digital currency and virtual currency, but they have not succeeded. There are not only technical reasons, but also social environment and economic background reasons. To some extent, it was the 2008 financial crisis that gave birth to bitcoin

4. Think again about having your own small hydropower

5. Bitcoin is not a company. Bitcoin is a consensus network that has led to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system

at present, bitcoin is still a small-scale large-scale socialization experiment, which is in the early stage of development, and the supporting infrastructure is not perfect. It is very difficult for some bitcoin start-ups to make profits at present. If there is no continuous large-scale capital entry, it is normal for them to go bankrupt. This is not the same company as the bank, but there are many enterprises that set up banks, and many banking enterprises will go bankrupt because of poor management. For example, the most typical example is Lehman Brothers bank. Bitcoin home network has a basic introction about bitcoin, you can learn about it.

historical background

bitcoin is one of the first currencies to realize the concept of "cryptocurrency". In 1998, Wei Dai first expounded the concept of "cryptocurrency" in cypherpunks mailing list. Based on the basic concept of money, which is used to pay for goods, services and debt or any form of records in a given country or economy, bitcoin is a new form of money. Its original design is to integrate the idea of not relying on the central authority, using the principle of cryptography to control the issuance and transaction of money
in 2009, Satoshi Nakamoto published the first bitcoin specification and its proof of concept in the cryptography mailing list. At the end of 2010, Nakamoto claimed that he had transferred to other affairs and left the project. The creator of bitcoin never revealed his true identity, but left his invention to the world. Today, the origin and motivation of the invention of bitcoin is still a mysterious story
since 2010, many developers have devoted themselves to this project, and the bitcoin community has grown rapidly. Between June and July 2011, bitcoin suddenly gained media attention, leading to large-scale buying. The resulting bubble led to the continued decline in the price of bitcoin in the second half of 2011. After that, the price of bitcoin graally rose to the height of 2011
in order to regulate, protect and promote the development of bitcoin, the bitcoin foundation was established on September 27, 2012. Nowadays, with the increasing number of bitcoin users, bitcoin economy is developing rapidly

When you heard that many people who bought bitcoin got rich overnight, Japan also legislated to accept bitcoin, and then the major businesses supported bitcoin payment... You also have grass in your heart. Although I don't know what this coin is, it seems to make a lot of money. Do you want to buy it for two yuan

With a wave of his hand, Mr. Nakamoto, you guys need not worry. In order to make money... Oh no, in order to save the economic crisis, I have already considered this small matter carefully. In order to ensure the authenticity and quantity of each coin, each of us has a small notebook. On this magical notebook, you can see the birth of each coin, and everyone is a witness. At the same time, for the sake of safety, our notebook also has a very cool function, which is to have an invisible lock. You can only see it, but you can't change it. This kind of bitcoin has authenticity and authority

at the same time, you can rest assured that bitcoin will not be used in vain. I have found many "bricks" of mainstream economics, analyzed bitcoin and predicted that it will become the mainstream currency in the future. Now you can dig (Jian) currency without spending a cent, and you can wait for the currency to appreciate. Isn't it super good

this boasting, we listen to the bious, some people go to dig (Jian) money, some keep watching. At this time, Nakamoto took action. In 2014, he secretly united with American e-commerce giants such as eBay, airbnb and Uber, which began to accept bitcoin payment. Since then, the bitcoin market has really begun. Many people know that there is money coming in vain, and they also begin to join the ranks of coin digging. However, the number of people is still small, and there are not many coins g up

until 2017, when the blackmail virus incident occurred and the whole world suffered from large-scale network virus attacks, the poisoning unit had only two choices, either waiting for the computer to GG and the data disappeared, or paying about RMB 2069 bitcoin to unlock

this made bitcoin instantly become global famous. At the same time, all units had no choice but to buy coins. At this time, the brothers who had been digging for (Jian) coins for five or six years had a collective climax. There were so many coins. You want to buy them, right. In this way, the value of pure virtual bitcoin without real value soared to $2151 / piece

since then, as you have heard, XXX has accumulated more than n bitcoins, which have soared ten thousand times and become rich overnight

up to now, the creator of bitcoin, Nakamoto Tsung, has become a fan of identity, but bitcoin is still not accepted by most countries, including China. At present, bitcoin's high trading volume is also an illusion. Most of them are bad speculators. Through high-frequency trading, they create an illusion to attract investors' attention. This practice is equivalent to Taobao's swiping orders

for you who want to invest, you still need to clarify some things

1. Bitcoin is not restricted by law, and of course it is not protected. Once your trading platform is attacked by hackers, your currency will be lost, there will be no place to find it, and there will be no place to reason Many people go to the rooftop)

2. The fluctuation is very great. You only see a ten thousand fold increase, but not a half drop overnight

3, bitcoin has no issuer. In today's financial world, the currency of no issuer is worthless, and the bubble economy may collapse at any time. p>

the last word of advice: don't touch bitcoin as a rookie, or the old bird will speculate and run when they earn money, otherwise they will be sad

8. It was initiated by Fuhui China.
