1. In order to understand the technical principle of bitcoin, we need to understand two important cryptographic techniques: hash code: it converts a long string into a fixed length string, and its conversion is irreversible, that is, it is impossible to guess the original string from hash code. Sha256 is mainly used in bitcoin protocol
public key system: corresponds to a public key and a private key, keeps the private key in the application and publishes the public key. When Party A transmits information to Party B, it can use Party A's private key to encrypt the information, and Party B can use Party A's public key to decrypt the information, so as to ensure that the third party cannot impersonate Party A to send the information; At the same time, when Party A transmits information to Party B, it is encrypted with Party B's public key and sent to Party B, and then Party B decrypts it with his own private key, so as to ensure that the third party cannot eavesdrop on the communication between the two people. RSA is the most common public key system, but the lliptic curve digital signature algorithm is used in bitcoin protocol. What's the difference between cash and bank account? Bitcoin is an electronic currency in BTC. In this article, it is also used to refer to the whole bitcoin system. Like opening an account in a bank, the corresponding concept in bitcoin is address. Everyone can have one or more bitcoin addresses, which are used to pay and collect money. Each address is a string that starts with 1. For example, I have two bitcoin accounts, and. A bitcoin account is uniquely determined by a pair of public key and private key. To save the account, you only need to save the private key file. Unlike bank accounts, banks keep all transaction records and maintain the book balance of each account, while bitcoin's transaction records are jointly maintained by the whole P2P network through a pre agreed protocol. How much money is in my account address? Although the current account balance can be seen by bitcoin software, unlike banks, there is no place to maintain the book balance of each address. It can only calculate the account balance in real time through all historical transactions. How do I pay? When I pay from address a to address B of the other party, the payment amount is e. at this time, both parties will announce the transaction information to each network node, telling address a to pay to address B, and the payment amount is e. In order to prevent the third party from forging the transaction information, the transaction information will be encrypted with the private key of address A. at this time, the network node receiving the transaction information can use the public key of address a to verify that the transaction information is indeed sent by address a. Of course, trading software will help us do these things, we just need to input the relevant parameters in the software. What will the network node do after receiving the transaction information? This is the most important part of the bitcoin system, which needs to be elaborated. For the sake of simplicity, only bitcoin protocol has been implemented. In the current version, each network node will save all transaction information synchronously. There are two kinds of transaction information in history, one is & quot; Verified & quot; The transaction information, that is, the verified transaction information, is stored in a series of "blocks". Each & quot; block" Is the previous & quot; bock" The ID of each block is the hash code of the hash code of the block and the new transaction information (see an actual block). The other category refers to those who also & quot; Unverified & quot; The transaction information just paid above belongs to this category. When a network node receives new unverified transaction information (possibly more than one), it can calculate the book balance of each address at that time because the node keeps all the transaction information in history, so it can calculate whether the transaction information is valid, that is, whether there is enough balance in the payment account. After eliminating the invalid transaction information, it first takes out the last & quot; block" Then, the unverified transaction information is combined with the ID, and a verification code is added to form a new "block". It needs a lot of calculation to build a new block, because it needs to calculate the verification code, so that the above combination becomes a block, that is, the first several bits of the hash code of the block are 1. At present, the first 13 bits need to be 1 (generally, the specific method is uncertain), which means that if the block is generated by enumeration method, the average number of enumerations is 16 ^ 13. Using CPU resources to generate a block is called "gold mining", because the proction of the block will get a certain reward, and the reward information has been included in the block. When a network node generates a new block, it will broadcast to other network nodes. However, this network block may not be accepted by the network, because it is possible that other network nodes have proced the block earlier. Only the earliest block or the block with the largest number of subsequent blocks is valid, and the remaining blocks are no longer used as the initial blocks of the next block. How does the other party confirm that the payment is successful? When the payment information is distributed to the network node, the network node begins to calculate whether the transaction is valid (that is, whether the account balance is enough to pay), and attempts to generate blocks containing the transaction information. When six blocks (one direct block and five subsequent blocks) contain the transaction information, the transaction information is considered "verified", so that the transaction is formally confirmed, and the other party can confirm the successful payment. A possible problem is that I will pay the balance of address a to address B, and at the same time pay to address C. If I only verify that the single comparison transaction is valid. At this point, my way of cheating is to generate six blocks including B to B and six blocks including C to C before the truth is revealed. Because I need a very long CPU time to generate a block, compared with the whole network, the probability of my cheating success is very small. What is the motivation of network nodes to proce blocks? As can be seen from the above description, in order to make the transaction information effective, the network node needs to generate 1 and 5 subsequent blocks to contain the transaction information, and such block generation is very CPU intensive. How to let other network nodes help to proce blocks as soon as possible? The answer is very simple. The agreement stipulates that BTC will be rewarded for the address where the block is proced, as well as the Commission promised by both parties. At present, the reward for procing a block is 50btc, which will be halved every four years in the future. For example, the reward will be 25btc from 2013 to 2016. Is the transaction anonymous? Yes, and No. All bitcoin transactions are visible. We can check all transaction records of each account, such as mine. But what's different from the banking monetary system is that everyone's account itself is anonymous, and everyone can open many accounts. In general, anonymity is not as good as it claims. But bitcoin has another advantage in doing black market trading: it can't be frozen. Even if the police trace a bitcoin address, there is nothing they can do unless they trace the computer used by the exchange based on the Internet address. How to ensure that bitcoin does not depreciate? Generally speaking, in the case of equivalent trading activities, the value of money is inversely proportional to the amount of money issued. Unlike the traditional money market, the central bank can determine the amount of money issued. Bitcoin does not have a central issuing institution. Only by procing blocks can we get a certain amount of BTC currency. Therefore, bitcoin's new amount of money depends on: 1. The speed of procing blocks: bitcoin's agreement stipulates that the difficulty of procing blocks is fixed at an average of 2016 every two weeks, about 10 minutes. Moore's law of doubling CPU speed every 18 months will not speed up the proction of block. 2. The number of rewards for block proction: at present, 50 BTC is awarded for each block proced, which is halved every four years. In 2013, 25 BTC is awarded, and in 2017, 12.5 BTC is awarded. Considering the above two factors, bitcoin's currency issuing speed is not controlled by any single node in the network. Its protocol makes the currency stock known in advance, and the maximum stock is only 21 million BTC
public key system: corresponds to a public key and a private key, keeps the private key in the application and publishes the public key. When Party A transmits information to Party B, it can use Party A's private key to encrypt the information, and Party B can use Party A's public key to decrypt the information, so as to ensure that the third party cannot impersonate Party A to send the information; At the same time, when Party A transmits information to Party B, it is encrypted with Party B's public key and sent to Party B, and then Party B decrypts it with his own private key, so as to ensure that the third party cannot eavesdrop on the communication between the two people.

According to the official annual report of the securities and Exchange Commission, form 10-K, Tesla has invested a total of US $1.5 billion (about RMB 10 billion) in bitcoin, and expects to accept digital assets as a payment option in the near future. Tesla is expected to begin to accept cryptocurrency as a means of payment, according to the report by Bloomberg. Before that, musk, the founder of Tesla, was still selling dog coins. Stimulated by the news, bitcoin soared instantly. By the time of publication, bitcoin had soared by more than 15% and stood at US $44000. According to bitcoin home, the market value of bitcoin has exceeded US $820 billion, surpassing that of Facebook (at US $758.619 billion) compared with the market value of well-known companies
at the same time, the block chain related to cryptocurrency also soared. The blockchain plate of the US stock market rose in the short term before trading. Before trading on February 8, the blockchain plate of the US stock market surged in the short term. For a time, the ninth city rose by more than 28%, riot blockchain rose by more than 20%, marathon patent group rose by more than 25%, Jianan technology rose by 19%, and bit digital, Inc rose by more than 24%
3. Bitcoin is a kind of cryptocurrency based on decentralization, using peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology. Under normal circumstances, an ordinary home computer can bear up to 1000h / s of computing power. According to the hash collision data of bitcoin 3 million times per second, if it is just an ordinary home computer, even if it is mining 24 hours a day, it can dig up to 0.0018 bitcoins a day. It takes at least 556 days to dig out a complete bitcoin. If it is not lucky in the middle of the way, it will be difficult to dig out a complete bitcoin, It may take more time

4. Not only are gold and bitcoin irrelevant, they even represent different asset classes. You can't compare bitcoin and gold as apples and oranges
Shelley Goldberg, a well-known investment consultant working for brevan Howard asset management and Roubini global economics, believes that as an analogy, it is like soybean futures and Intel stock. Many people may think that gold and bitcoin are both currencies because they can be used to buy goods and services. Or, both are commodities, because trading commodity futures needs to meet the minimum standards of account opening funds, and comply with the relevant futures and option contracts. But gold is a commodity, bitcoin and blockchain are technologies
in what unit are abstract things measured
Stefan Weiler, vice president of goldmoney, a global financial services and technology company, believes that gold is real and has physical and measurable natural advantages, rather than abstract man-made money, including fiat money. Therefore, gold has measurable mass and weight to determine its unit (gram, Troy, ounces, etc.). But bitcoin doesn't have this feature. Weiler pointed out that "abstract things can only be measured in their own units.". So the bitcoin value of "weighing" is literally not comparable to the value of gold
Stefan has worked in the world's top financial institutions for more than 10 years. He was senior director of commodity strategy at Goldman Sachs and research director of commodity hedge fund BBL commodities. In 2014, the hedge fund gained 51.3% return and won the title of "new fund of the year"
Weiler explains this problem by comparing the units between bitcoin and gold:
when comparing the units of gold and bitcoin, we must first define which unit to measure, gram... Kilogram... Or ton? Or ounces? Weiler uses the market capitalization of the two companies (apple (NASDAQ: AAPL) and seaboard (nysemkt: SEB) as a metaphor to illustrate how unit size / amount distorts the price: comparing the price of a unit of bitcoin and an ounce of gold is a bit like comparing seaboard's shares (US $4179 per share) with Apple's shares (US $116 per share), and concludes that, Seaboard's market value is about 35 times that of apple. Considering only the stock prices of the two companies without considering the shares (i.e. units) issued, it is obviously not enough. Weiler believes that a similar situation will occur when comparing gold and bitcoin
neither is money
by definition, money is a widely accepted means of payment as a medium of exchange. The classification of gold as a commodity currency goes back a lot to the early days of capitalism, when people could trade gold for cattle. But this model doesn't work because gold is often in short supply. Gold is a tradable tool and asset-backed currency, because it can be exchanged for a certain amount of US dollars, but if you take the gold nugget to the grocery store to buy something, the grocery store will not sell it to you. Unless we go back to the Bretton Woods system when gold was fixed against the US dollar, gold is not directly linked to any currency
there is no doubt that bitcoin is becoming an acceptable means of payment both offline and online, such as offline stores, home depot and online transactions, such as expedia.com, which are also accepted by many countries, such as Estonia and Denmark. But it is still not widely accepted around the world
money is national legal, which means that each Congress uses it in monetary policy. The Fed can print as many dollars as it can to stimulate the economy. At present, more than 50 banking organizations in the world have joined the R3 blockchain alliance, but bitcoin does not rely on the government, banks and other third parties
unlike money, both gold and bitcoin are in limited supply. The gold supply of the earth depends on the underground reserves, and the creation limit of bitcoin is 21 million
Goldberg believes that although the value of bitcoin exceeds that of gold for the first time, there is no comparability between bitcoin and gold
the two are not irreplaceable
gold was first used around 700 BC, and after that, nothing with the same properties as gold has been found or created. Metallurgists have made alloys that look and feel like gold, but they are not gold because they do not meet physical delivery standards. Bitcoin, on the other hand, has numerous alternatives, because countless "altcoin" cryptocurrencies have sprung up to challenge it, such as Ethernet, which follows Casper rules
according to cryptocoincharts, the market value of 3694 cryptocurrencies has reached 27.8 billion US dollars. Of course, bitcoin has an overwhelming market share, but who knows what other cryptocurrency popularization or some technology will challenge and destroy the current market in the future. Not long ago, many bitcoins were stolen from Mt. GOx exchange. Last summer, a project using blockchain technology was hacked and lost millions of dollars. So there is still room for improvement
gold is a commodity, but bitcoin is not. Gold is a basic commodity or hard asset that can be used in business, and it can be used as a material to proce other commodities. People can also use gold for physical delivery and then make it into some other form for use. Although bitcoin is storable, it is not physical and cannot be held, felt or transferred. " Goldberg said
are bitcoin and gold risk averse
for centuries, gold has been regarded as a safe haven asset or used as a hedge against inflation, but this attribute is not permanent, because there are many alternatives, such as the Swiss franc and tips. Bitcoin is different. In fact, China's three largest bitcoin exchanges recently stopped withdrawing money under pressure from the people's Bank of China for fear that bitcoin would be used to transfer money abroad. Bitcoin has not experienced inflation since its birth, so its anti inflation property has not been verified< However, they are similar. Shelley Goldberg believes that bitcoin and gold are rare, their prices may be volatile, and each serves as an alternative investment to those lacking confidence in legal tender and monetary policy. Bitcoin trading is not as easy as gold, because people have to buy bitcoin through online trading platforms or invest in over-the-counter bitcoin trusts. There may be a bitcoin ETF in the near future, as the US Securities and Exchange Commission is considering a proposal to launch an exchange traded fund backed by bitcoin. A final decision will be made by this Saturday
on February 14, SEC officials met with brother Tyler Winklevoss and brother Cameron Winklevoss, advocates of bitcoin ETF, to discuss the above proposal. The market expects that once bitcoin ETF is listed, it will attract a large amount of capital investment, reaching at least $300 million. With this development, bitcoin will become an easier trade
cryptocurrency supporters believe that bitcoin is the medium of exchange and storage value in the future. However, the volatility of bitcoin is a problem when only the downlink deviation is measured instead of the standard deviation& quot; This method better shows the risks of bitcoin becoming a widely used currency, "Weiler said
in his analysis, Weiler believes that "the volatility of bitcoin is significantly higher than that of gold and currency
Weiler believes that although bitcoin's short-term performance is impressive, it still has serious limitations in terms of utility and savings compared with gold and precious metals. At the same time, Shelley Goldberg also believes that the relative value of bitcoin is basically nothing except speculation. In addition to the expectation that trump will relax the financial regulatory environment in the United States, China, India, Venezuela and other countries have tightened the supervision of bitcoin. Therefore, with the currency instability in emerging markets, the uncertainty of Trump's policy and the expectation of stock market adjustment, there are still good reasons to buy gold.

5. Bitcoin (English: bitcoin, abbreviated as BTC or XBT) is a kind of cryptocurrency based on decentralization, adopting point-to-point network and consensus initiative, open source, and blockchain as the underlying technology. Bitcoin was published by Satoshi Nakamoto on October 31, 2008, and Genesis block was born on January 3, 2009. In some countries, central banks and government agencies, bitcoin is regarded as a virtual commodity rather than a currency
anyone can participate in bitcoin activities, which can be issued through computer computing called mining. The number of bitcoin protocols is capped at 21 million to avoid inflation. Bitcoin is used as a digital signature through the private key, which allows indivials to pay directly to others.
