Reasons for the rise and fall of blockchain

1. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

2. In one sentence, it is decentralization
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
the so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing method, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data< Advantages:
1) the algorithm is simple and easy to implement
2) there is no need to exchange additional information between nodes to reach a consensus
3) it takes a lot of cost to destroy the system< Disadvantages:
1) waste of energy
2) it is difficult to shorten the block confirmation time
3) the new blockchain must find a different hash algorithm, otherwise it will face bitcoin attack
4) it is easy to generate bifurcation and needs to wait for multiple confirmations
5) there is no finality, and checkpoint mechanism is needed to make up for it.

The Open Market Committee expects to raise interest rates three times next year, and the market expects to raise interest rates two times. On the other hand, bitcoin is better than the market www.toubi.com According to the data above, it rose from more than 5400 points in the early 15th to more than 5600 points today. The increase of interest rate by the Federal Reserve not only did not cause the decline of bitcoin, but also caused a small rise. What makes bitcoin rise under the influence of such a big policy?

Looking at China's global price trend, I can tell you the story behind each candle chart along the way. The range of rise and fall is very large, but all investors can see clearly why it will rise and why it will fall, Bitcoin is a kind of network virtual currency, which is characterized by decentralization, anonymity, can only be used in the digital world, does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Its characteristics make us firmly believe that bitcoin will become a mainstream currency in the future. Just like diamonds, at the beginning, someone picked up some shiny things by the river or on the beach, which was caused by...

after four months of silence, bitcoin and other virtual currencies once again attracted the attention of the market because of the crash. Analysts said the reason for bitcoin's collapse was e to leveraged trading. On Monday night, the price of bitcoin on btc-e, a bitcoin trading platform, dropped rapidly to $309, nearly 40% from the highest price of $498 on that day. However, after the slump, bitcoin prices slowly rebounded. The new hope of electronic currency: the political and economic changes behind the rise and fall of bitcoin. Edwin van der Brom, a former bitcoin trader and Dutchman, is in endless regret these days.

(1) Technical level. Since 2007, distributed computing has affected technical developers, so it is normal for bitcoin to appear in the field of virtual currency

(2) hardware level. The popularity of PC servers and the exponential growth of computing power

(3) commercial level. The three characteristics of blockchain, namely, decentralization, distrust and extremely difficult forgery, just meet the needs of recing the trust cost and speeding up the transaction speed in financial fields such as stock trading and bank settlement

(4) political level. Blockchain can rece the transaction cost to a certain extent, but the anonymity and untraceability of blockchain cause huge political risk

To tell you the truth, this question will become very big if it is unfolded. If I want to write clearly my personal feelings from the beginning to the end, it will become smelly and long. So I want to use a few simple aspects and my personal views to answer this very difficult question

let's briefly talk about what bitcoin is, because this simple problem is misunderstood by most people at present. Because it is called "bitcoin", because there is a currency, this word naturally equals to RMB, US dollar, franc and other legal compensation currencies. In fact, this is totally wrong. The definition of legal currency is "the currency given by the state in the form of law for compulsory circulation". When bitcoin appeared, it was written in the white paper that the e-cash system was completely realized through point-to-point technology, which enables online payment to be directly initiated by one party and paid to the other party without any financial institutions

so what exactly is bitcoin? To be exact, it should be regarded as a commodity rather than a currency, because you can see in the white paper that "there is no need to go through any financial institutions". When bitcoin was created by Nakamoto, it was intended to change the life of the bank which was not trusted by the people because of the economic crisis. But we say the vision is good, but the reality is cruel. Even Alipay with 1 billion users can't get rid of the bank's life, let alone a small bitcoin. p>

but you can say why bitcoin is still used by many people for trading and its price is not low, that is because its market demand is very large, resulting in its high price. What is this demand for? Let's talk about it next time. In a word, its high market demand leads to high price. What is bitcoin? I prefer to compare it to a hard currency or a very scarce commodity. Like gold. Let's take a look at an interesting figure:

to tell you the truth, the development of blockchain is very, very early now. All of a sudden, so much capital has poured in, which makes everyone crazy. When the slump comes, it's a bit at a loss. Now the price of bitcoin is more stable, which gives more time for many people who are calm down to do things

out of trust in blockchain technology, bitcoin, as the genesis currency of blockchain, will have a place in the future. Money price is not the most important thing. But make a bold guess. Bitcoin or digital virtual currency will definitely recover in early 2020 and mid-2019. The bull market will come at that time. Is it possible to go back to $2W? Maybe more. Maybe

in the future world I imagine, blockchain technology will surely create a happier and better future for mankind. And the accompanying bitcoin will certainly lead to a bull market

is to read more about the various currencies or project's white paper. I pay attention to my WeChat official account: "Nanjing block chain" can get thousands of white papers free of charge, so that you will have a better understanding of the chain world. p>
