㈠ The market value of Bitcoin has exceeded 1 trillion. Musk has invested heavily in the game. What is the secret behind it?

In 2021, the market value of Bitcoin has exceeded 1 trillion US dollars. This makes There seems to be too much behind the things that the world is crazy about that cannot be understood.

Who is Satoshi Nakamoto, the inventor of the Bitcoin algorithm? It is still a world-class unsolved mystery. All the cryptocurrency circles and hackers in the world are looking for him, but no one can find him because he has never appeared in public view.

It is estimated that there are about 1 million to 1.1 million Bitcoins in Satoshi Nakamoto’s Bitcoin wallet. Everyone is staring at this wallet. The strange thing is that since the advent of Bitcoin, this wallet has never used Bitcoin externally. , so that means there is such a person in the world who does nothing, but may become the richest man in the world at any time.

Many people became rich overnight because of Bitcoin, such as China’s Li Xiaolai. However, the biggest unlucky guy has also appeared in the history of Bitcoin. Compared with him, none of you are miserable.

On May 22, 2010, a programmer named Laszlo Hanyez purchased two pizzas with 10,000 Bitcoins, and the first real-world Bitcoin transaction was born. As the value of Bitcoin rises, the theoretical value of that pizza becomes more and more expensive. At the current price, it is equivalent to 500 million U.S. dollars, or 3.245 billion yuan to buy two pizzas. I don’t know what the programmer is doing now. Thoughts.

On February 21, 2021, the market value of a certain Baba was US$714.9 billion, and the market value of a certain news was US$924.2 billion. On that day, a single Bitcoin was US$56,590, and the total market value exceeded US$1.245 billion. The current market value ranks only behind Apple. , Saudi Arabia, Aramco, the parent company of Microsoft, Amazon and Google, after 5 companies.

Speaking of which, everyone can’t believe that something without collateral, something with a value of 0, something that has never even appeared in the physical world, has been heavily stocked not only by American financial institutions, but also by the world. Musk, the richest man, bought a lot and allowed it to be used as payment currency for Tesla.

Recently, many states in the United States have been allowed to try to pay wages as a legal currency transaction, which makes people think deeply about the madness of the world and the accelerated virtualization of world finance. An algorithm that does not exist in the real world is So worth a trillion dollars.

On October 31, 2008, an account signed by Satoshi Nakamoto brought the concept of Bitcoin to the world for the first time in a secret forum cryptography discussion group, using a document to explain the concept of cryptocurrency. It is not issued by a central bank or authority and allows transactions between two anonymous persons.

In mid-January 2009, Satoshi Nakamoto released the earliest version of the open source client on the cryptography mailing list. Anyone can participate in Bitcoin activities through a process called "mining."Issuing by computer calculation.

The principle of Bitcoin is already known to many people, but it is no longer popular science. Read on.

In the early days, too many people mined a large number of Bitcoins, but forgot the keys because the value was too low at the time. Therefore, the total number of Bitcoins actually circulating will be far less than 21 million in the future. The total number of Bitcoins has an upper limit and cannot be overissued, which creates a natural attribute of it: there is no inflation problem and it will only become more and more scarce.

Bitcoin uses blockchain technology to realize value storage and transactions. You don’t need to know what a blockchain is. It can be simply understood as a public electronic ledger, such as stock exchanges in the early days. Everyone stands in front of the big screen in the hall, and any change in stock price and number of transactions is broadcast simultaneously throughout the system.

Whether it is people in the exchange hall or the Shanghai Stock Exchange thousands of miles away, the system broadcast speed in the Shenzhen Stock Exchange hall is public and synchronous, and every participant can view and join, and That is to say, no one can operate in the dark, tamper with data, or interfere with the operation of the system by any means.

Let’s first take a look at the Bitcoin private key, which is the principle of generating private passwords. When you toss a coin, it will be 1 if it comes up heads, and 0 when it comes up tails. Toss it 256 times in a row, and convert the result into a 16-digit number, which is the key to the next Bitcoin.

In other words, the essence of the Bitcoin private key is a 256-bit binary number. It sounds ordinary, but do you feel that it can be easily cracked with an ordinary computer? The average math teacher who can think this way is already crying in the toilet. Two to the power of 256 is equivalent to eight times two to the power of 32 multiplied, and 2 to the power of 32 is approximately equal to 4 billion. That’s 4 billion 4 billion 4 billion 4 billion 4 billion 4 billion 4 billion times 4 billion.

Let’s put it this way, even the fastest quantum computer can’t crack the private key of Bitcoin. So if you are a Bitcoin holder, remember not to forget your private key. key.

The reason why Bitcoin has intrinsic value is because of its absolute security, its monetary nature and the fact that you can carry millions or even hundreds of millions of dollars with you just by remembering a bunch of keys. The value of the dollar is stored in your own brain without any restrictions.

Next, let’s talk about another important intrinsic value of Bitcoin: liquidity and non-regulatory nature, which is what we call decentralization.

Bitcoin uses a private key as a digital signature, allowing individuals to pay directly to others. It is the same as cash. It does not need to go through bank settlement centers, securities dealers’ electronic payment platforms, and most importantly, it does not go through national financial supervision. Systematic third-party institutions avoid the cumbersome process of handling fees, taxes and funds being subject to state supervision during the transaction process.

Any user canThe connected Internet can all use decentralization, which can be described in four words: There is no power in the world.

Imagine how chaotic a society without laws and legal systems would be. At the capital level, what kind of group interests does Bitcoin represent? Since its inception, financial capital has been chasing flows and making profits. It naturally hopes that there will be no foreign exchange controls or financial supervision, and capital can flow without borders, and even participate in any shady but high-profit investments. Therefore, financial capital must hope to degovernmentalize and get rid of government supervision. The more convenient and free the liquidity of financial capital, the easier it will be for financial consortia to make profits. This is in conflict with the fundamental interests of most countries.

The issuance of legal tender and the control of legal tender are core interests that every sovereign country needs and must master.

Many major countries, represented by our country, do not legally recognize the currency attributes of Bitcoin, but in the world Several countries are gradually trying to accept the legalization of Bitcoin, including a very small number of countries represented by the United States in the West. Why does the United States support Bitcoin?

Some netizens say that Musk supports decentralization of the US dollar. In fact, he is just betting that the US dollar will regain blockchain hegemony.

Some netizens also said: Musk, the world’s richest man, has personally supported Bitcoin. Does this mean it has great investment value? This is typical leek thinking, read on.

When Musk announced his entry into Bitcoin on February 8, he announced that he had purchased US$1.5 billion in Bitcoin. Obviously, the Bitcoin he holds should be far more than 1.5 billion. One point, in less than two weeks, Bitcoin became US$38,000 and rose to US$56,000, making a profit of US$1 billion. Isn’t this much easier to make than building a car? Would you go out on your own every day to badmouth a product in which you have invested billions of dollars?

Obviously, it is easy to drive up the value of virtual currencies with his new title of "world's richest man" and "global technology leader" and the skyrocketing capital in his hands in the past year. of.

No one fights money. Other capitals naturally responded to the call and came in to support the sedan. When these big capitals felt that the bubble was too big in the short term, it was time for this period of leeks to harvest a lot of selling.

Bitcoin, a thing with no collateral and a value of 0, will be worth trillions

Satoshi Nakamoto, a "person" that even the world's hackers can't find< /p>

Bitcoin is an invisible tool for harvesting the world’s wealth, and it is also a trading tool in the darkest world in the world. Who is the invisible hand that controls Bitcoin?

Please tell us your answer in the comment area.

㈡Blockchain platform, which one does well?

First of all, you must choose according to your needs. You must also pay attention to the strength and effectiveness of the team. I understand that Baker Chain is doing a good job in blockchain. You can consult first.

㈢ What is the concept of blockchain? Read it in three minutes!

On October 25, 2019, Xinwen Broadcast sent a very important signal: the country must vigorously develop blockchain. After that, blockchain has become an Internet celebrity, and the figure of "blockchain" is floating in the streets and alleys. In fact, many technology companies have already deployed blockchain technology.

Although blockchain is very popular, many people do not know much about blockchain.

What is blockchain?

Let’s first take a look at how Du Niang explained it. Network display: Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms.

Why is blockchain called blockchain?

The blockchain is linked by blocks one by one, and the blocks are storage units that record the communication information of each block node. The blocks are much like the records of a database. Each block is a storage unit. Writing data every time creates a block. With the expansion of information exchange, one block continues with another, and the result is called a blockchain.

What are the characteristics of blockchain?

Blockchain mainly has the following characteristics:

1. Decentralization: In the blockchain system, every node has equal rights. and obligations, there is no central control here. Decentralization has well established trust relationships with each other. Although there is no central management organization, people can collaborate with each other and trust each other. This mainly applies blockchain distributed ledger technology.

2. Openness: Blockchain data is open to everyone. Except for some encrypted information that is not open, everyone can check the data here.

3. Independence: The entire blockchain system does not rely on other third parties. All nodes can automatically and securely verify and exchange data within the system without any human intervention.

4. Security: Blockchain has a certain degree of security and cannot be tampered with. Because everyone in the blockchain system has the same ledger, if someone wants to tamper with it, it is possible to forge a non-existent record only if they control more than 51% of the accounting nodes. Of course, this is basically impossible. This is mainly due to the core technology of the blockchain: the consensus mechanism. The consensus mechanism has the characteristics of "the minority obeys the majority" and "everyone is equal".

5. Anonymity: Many people think that blockchain is so open and transparent, does that mean we have no privacy? In fact, no, although the transaction information in the blockchain is open and transparent, the identity information of the account is encrypted and can only be accessed with authorization.

Now let me tell you a story to help you better understand the blockchain.

There are three people in the family, mom, dad, older brother and younger brother. Last year, my father was in charge of the family's account books. He was responsible for all the family's income and expenses alone.

However, on the day of Double Eleven, my mother, who has always been frugal, wanted to buy herself a beautiful piece of clothing on a certain online store. When she checked the account book, she found something was wrong. It stands to reason that except for some money deposited in banks and financial management, the whereabouts of the daily consumption money at home are all in this account book, but no matter how you look at it, it is wrong. Some consumption is clearly not recorded, but is recorded.

Later, my father took the initiative to confess that he couldn’t help but buy a pack of cigarettes.

Later, my mother changed her strategy and the whole family kept accounts. Everyone recorded their monthly consumption expenditure in their own account books. Whenever there was a transaction or consumption at home, my mother would shout, "Book it," and everyone would record the transaction in their own books. This is the decentralized accounting model, where everyone is the center and everyone has a ledger.

The previous accounting model for dad was centralized accounting. If dad wanted to do something alone, it would be difficult for anyone to see it. The decentralized accounting model has solved the problem of centralization very well. The disadvantage of bookkeeping is that it is very difficult for dad to tamper with the books.

For example, if dad wants to take some money from the ledger and secretly buy cigarettes, the amount of money is limited, and if he wants to take the money, he has to change the ledger, but he only tampered with his own ledger. No, he had to change the accounts of three people including himself. And this is undoubtedly more difficult than reaching the sky.

So, many times my father had the idea of ​​smoking, but he had no choice but to give up the idea due to the current situation.

Are blockchain and Bitcoin the same thing?

In fact, blockchain and Bitcoin are not the same thing. It is just the underlying technology of Bitcoin. Bitcoin is the first digital currency applied by blockchain.

In 2008, Satoshi Nakamoto first proposed the concept of blockchain. In the following years, it became the core component of the electronic currency Bitcoin, serving as a public account book for all transactions. Blockchain was first applied to Bitcoin.

The origin of blockchain is to solve the problem of trust, and one of the most successful applications of blockchain is digital currency. Bitcoin is arguably the most successful application of blockchain so far.

What are the applications of blockchain?

The application of blockchain is actually very wide. In addition to digital currency, the future applications of Bitcoin are still very extensive. Blockchain technology has been widely used in different industries. Such as product traceability, copyright protection and transactions, payment and settlement, Internet of Things, digital marketing, medical care, etc., promoting different industries to quickly enter the "blockchain+" era.

1. Payment and clearing: Blockchain can abandon the role of transit banks, realize point-to-point payment, reduce transit fees, and accelerate fund utilization.

2. Product traceability: For example, if we buy a piece of clothing on a certain store, we can see the past and present life of this piece of clothing.

3. Securities trading: Traditional securities trading requires the coordination of four major institutions, which is inefficient and costly. Blockchain technology can independently complete one-stop services.

4. Supply chain: Introducing blockchain technology into the supply chain system, synchronizing information within the system can control all links, better complete division of labor and collaboration, and facilitate subsequent accountability.

5. Intellectual property rights: With copyright on the chain, our photographic works, musical works, literary works, etc. will become our information, and the ownership of the information will be confirmed and become our property.

㈣ Analysis of the relationship between distributed and blockchain

We have talked about the discussion of blockchain technology many times in previous articles, and also I have introduced to you which programming development languages ​​are used to realize the realization of the blockchain insight chain technology. Today we will learn together how to analyze and understand the structure of the blockchain from a distributed perspective.

Blockchain is the underlying technology in Bitcoin and is used to implement a centerless peer-to-peer cash system. Because there is no central organization involved, Bitcoin uses blocks Organize transaction data in the form of a chain to prevent "double spending" and reach transaction consensus.

Digital assets in the traditional sense, such as game currency, are managed in a centralized manner and can only be transferred in a single system, coordinated by a centralized organization. , usually stored in a database. From a macro perspective, blockchain and database are both used to store data, but the form of data access is different.

The blockchain is essentially a distributed database that is active in different places. The idea of ​​multi-activity in different places was originally to solve the disaster recovery problem of the system. It has been a direction explored in the field of distributed databases for many years, but with little success because multi-activity in different places needs to solve the problem of data conflicts. This problem is actually Not easy to solve. However, the blockchain born in Bitcoin has realized the world's largest remote multi-active database in a completely new way. It is completely open, has no boundaries, supports tens of thousands of nodes and can join and exit at random.

The problem of data conflicts is even more prominent in the blockchain. Each node in the blockchain is a completely peer-to-peer multi-active architecture.Tens of thousands of nodes have to reach an agreement, who should the data be based on? The method adopted by Bitcoin is POW. Everyone comes to calculate a puzzle. Whoever calculates it first will have the right to keep accounts. In this cycle, the account he keeps will be used. Subject to this, everyone will recalculate in the next cycle. Nodes competing for accounting rights decide which Quanlu transactions are packaged into blocks and synchronize the blocks to other nodes. Other nodes still need to verify the transactions in the block based on local data, unlike the master-slave nodes of the database. This is the consensus algorithm in the blockchain. Although POW consumes a lot of computing power, the advantage is that in the process of competing for accounting rights, POW only needs to calculate hashes in its own nodes and does not need to go through network voting for election. The cost of network communication is small, and it is suitable for consensus among large-scale nodes. Beijing Computer Training believes that POW is a complete, simple and crude method in the current public chain and can stand the test, but the problem is that the efficiency is too low.

So PoS and DPoS were developed later. Whoever has more assets will have the right to bookkeeping, or everyone will vote, but this also introduces economic problems. For example, the so-called vote-buying issue is difficult to control. In traditional distributed databases, it is not called a consensus algorithm but a consistency algorithm, which is essentially the same thing. However, the number of nodes in a distributed database is generally very small, and the network is trustworthy. Usually the nodes are safe and reliable. We can basically trust every node. Even if it fails and does not respond, it will never respond. False response. Therefore, in traditional company distributed data, Raft or Paxos protocols are used to implement this consistency algorithm.

㈤ Does anyone know where blockchain development is better? What about companies that do blockchain?

Smartcontract (smartcontract) The term dates back to at least 1995 and was coined by prolific interdisciplinary legal scholar Nick Szabo. He mentioned the idea of ​​smart contracts in several articles published on his website. His definition is as follows :

"A smart contract is a set of promises defined in digital form, including an agreement on which contract participants can execute these promises. "

Let's explore the meaning of his definition in more detail.

Commitments

A set of commitments refers to a set of commitments agreed upon by the parties to a contract (often mutually ) rights and obligations. These commitments define the nature and purpose of the contract. Take a sales contract as a typical example. The seller promises to deliver the goods, and the buyer promises to pay a reasonable price.

Digital form

The digital form means that the contract must be written in computer-readable code. This is necessary because as long as the parties reach an agreement, the rights and obligations established by the smart contract are controlled by a computer or Computer network execution.

Further explanation:

(1) Reaching an agreement

When do the parties to a smart contract come to an agreement? The answer depends on the specific smart contract implementation. Generally speaking, a contract is discovered when a party commits to its execution by installing the contract on the contract hosting platform.

(2) Contract execution

The true meaning of "execution" also depends on implementation. Generally speaking, implementation means active implementation through technical means.

(3) Computer-readable code

In addition, the specific "digital form" required by the contract depends very much on the protocol the parties agree to use.

Agreement

Agreement is a technical implementation (technical). On this basis, contract commitments are realized, or the realization of contract commitments is recorded. Which protocol is chosen depends on many factors, the most important being the nature of the assets being traded during the performance of the contract.

Take the sales contract as an example again. Assume that the participants agree to pay the payment in Bitcoin. The protocol of choice will obviously be the Bitcoin protocol, on which smart contracts are implemented. Therefore, the "digital form" that the contract must use is the Bitcoin script language. The Bitcoin Script Language is a non-Turing complete, imperative, stack-based programming language similar to Forth.

㈥ What can be done in the blockchain craze

1. Invest in digital currency (coin speculation)

Coin speculation is the most basic method, but speculation The nature of the market is to rise and fall sharply. Some people sing every night while others lose everything. How to do it? To put it simply, it is to select a currency-select a place-register-verify the certificate-recharge-purchase. As for exchanges, domestically you can choose Bitcoin China, OKCoin, Huobi, and China Bitcoin, while foreign ones include Bittrex, Poloniex, and Bitfinex, which have pretty good credibility.

As for choosing coins, you can look at the top ten virtual coins with relatively low market capitalization. At least some people are pursuing them, and the operation team behind them is generally good. Pay more attention to new coins and cryptocurrencies with relatively active trading volumes. It is easier to pull up low-priced coins; however, not all low-priced coins can participate. If you choose the trending long-moving average upwards, the risk is relatively small, and don't consider the short-selling ones.

Of course, the investment principles of digital currency are the same as other investments: don’t invest if you don’t understand, insist on value investment, and insist on long-term investment. The specific implementation is very simple: basically follow the six-word motto of the blockchain big V: stock up, configure, don’t look. Then invest in digital currencies like an investment fund.
