区块链是如何诞生和发展的,区块链是如何诞生和发展的过程

区块链技术是一种基于分布式记账技术，它可以记录任何类型的数据，并且这些数据可以被安全地存储和共享。它的诞生是由于在2008年金融危机之后，人们对金融系统的信任度越来越低。

区块链技术诞生于2009年，当时由一位名叫Satoshi Nakamoto的神秘人物创造了比特币，并使用了区块链技术作为其基础。比特币的诞生使得人们开始意识到区块链技术的潜力，并开始研究它。

随着技术的发展，区块链技术也在不断演变。在2014年，比特币开发者开始研究如何将智能合约技术应用到区块链上，这样就可以实现更多的功能。智能合约使得区块链技术可以被用于不同的行业，从金融到健康，从教育到物联网。

随着技术的进步，区块链技术也在不断演变。在2016年，比特币开发者开始研究如何将可扩展性和隐私保护技术应用到区块链上，这样就可以实现更多的功能。可扩展性和隐私保护使得区块链技术可以被用于更多的行业，从金融到分布式计算，从健康到物联网。

今天，区块链技术已经发展成为一种被广泛应用的技术，它可以被用于金融、健康、教育、物联网等各个领域。它的发展不仅改变了金融行业，同时也改变了其他行业，使得许多新的应用可以通过区块链技术实现，为人们的日常生活带来了更多的便利。

总而言之，区块链技术是一种发展迅速的技术，它可以被用于各种行业，为人们的生活带来更多的便利。

① What exactly is blockchain

From the perspective of its application, blockchain is a distributed shared ledger and database with decentralized It has the characteristics of non-tamperable and non-tamperable files, leaving traces throughout the process, traceability, collective maintenance, openness and transparency, etc. Blockchain originated from Bitcoin, and the first blockchain was born on January 9, 2009.

Blockchain can currently be divided into public blockchain, joint blockchain and private blockchain. Public blockchain means that any individual or group can send transactions, and the transactions can be effectively confirmed by the blockchain, and anyone can participate in its publicity process. As the name suggests, joint and private blockchains refer to a combination of multiple individuals or groups, and an individual or a company has exclusive write access to the blockchain. Basic difficulties

② What is blockchain and how was it born? What are the types of blockchain?

If you want to understand blockchain, you must first understand the basic structure of the program. Everything we see on the Internet is constructed through computer language. There are many kinds of computer languages, but the most basic characters that make up the language are codes, and blockchain technology is a way of applying codes, which is different from traditional centralization. The difference between the models is that the blockchain has the characteristics of immutability, privacy, security, and consensus.

There are many application scenarios for blockchain. The most successful case so far is Bitcoin, followed by electronic invoices, cross-border payments, etc. Based on the interoperability of data, it is impossible to With characteristics such as tampering, it can also be used to save some important data. As long as this data uses blockchain technology as the underlying technology, it can never be destroyed and will be saved forever. No person or institution has the ability to modify or delete it. In addition, there are certain intersections between blockchain payment and education, medical care, credit reporting, automobiles, transportation and other fields. It is a technology, not a certain product, so there is only one type of it, but with the application As the scene changes, its role is also different. It can be integrated with existing scenes in almost any field and then derive other applications.

③ Do you know the three important stages in the history of blockchain development?

As blockchain technology matures, blockchain technology has made significant progress in the financial field. Results. Whether they are investors, practitioners in related financial fields, or technology practitioners, they are all very concerned about blockchain. Many people or platforms have begun to devote themselves wholeheartedly to it, using blockchain technology to create a new financial system, and have achieved impressive results.

If you have studied blockchain, maybe you have a deeper understanding of blockchain. Since the birth of blockchain, in terms of applications, It has gone through three stages of change. There are important developments and inventions at every stage of blockchain technology. Blockchain technology only exists for a small part of the Internet's time., so it's very possible that there are still important developments.

The first technical stage

Bitcoin has been running since 2019. The main technology supporting the Bitcoin system includes hashing Technologies such as functions, distributed ledgers, blockchain, asymmetric encryption, and workload proof constitute the initial version of the blockchain.

At present, blockchain technology is not yet mature, the conservative tendency within many organizations is still obvious, and the use of centralized technology and processes in the market to make profits Intermediaries that collect revenue, equipment providers are also hyping up the concerns it may bring.

Second market phase

In early 2013, the price of Bitcoin began rise. In November of the same year, a U.S. Senate hearing clarified the legality of Bitcoin, and the price of Bitcoin rose sharply. But at this time, the blockchain has not yet reached the mainstream social and economic foundation, but its price has risen beyond expectations. At this time, the market opened up the visibility of Bitcoin and blockchain, but despite this, they still did not gain universal acceptance to a certain extent.

The third mainstream stage

Bitcoin, which is an alternative to the mainstream economy, began to recover. Market demand increased and transaction scale expanded rapidly. It also opened up the bull market of 2016-2017. . The enrichment effect of Bitcoin and the spillover effect caused by the congestion of the Bitcoin network have led to the explosive and crazy growth of other virtual currencies and various blockchain applications. At this time, it triggered a crazy global pursuit to make Bitcoin and blockchain a complete global vision.

In 2020, although the epidemic has dealt an important blow to our economy, the hot development of Bitcoin and blockchain tells us that they It is creating opportunities and driving related development. Just like the recent price of Bitcoin is close to 30,000 US dollars, such a market has brought surprises to many people, and it has also promoted the development of exchanges. After all, exchanges are the only way to buy Bitcoins. Its popularity is also It has brought good profits to exchanges, such as Huobi and Saturn Exchange, which have refreshed their historical trading volumes many times due to this bull market. In fact, no matter which industry develops, it will always drive multiple industries. After all, many things are always closely related.

④ What stages has the blockchain developed?

The five stages of blockchain development
1. Germination stage: The real germination stage of blockchain was in 2007 By 2009, a Japanese-American who went by the pseudonym Satoshi Nakamoto first appeared on cryptography discussion groups under a different name in 2008.A new fantasy report about electronic money was elaborated, and Bitcoin was born. As early as 2007, Satoshi Nakamoto began to explore a series of new technologies with the intention of creating a new currency. The Bitcoin white paper was released on October 31, 2008, and the Bitcoin system officially began operation on January 3, 2009.
The main technologies supporting the Bitcoin system include hash functions, distributed ledgers, blockchain, and asymmetric encryption; it can be seen that these technologies build the initial version of the blockchain, which can also be said to be a blockchain It is the underlying technology of Bitcoin. In the three years from 2007 to 2009, Bitcoin was in the experimental stage with the participation of a very small number of people, and real commercial activities had not really begun.
2. "Geek" niche stage: The "Geek" here refers to people who are enthusiastic about Internet technology and who regard technological innovation as their fashion and life. The first Bitcoin exchange appeared on February 6, 2010. On May 22 of the same year, someone bought 2 burgers with 10,000 Bitcoins. On July 17 of the same year, the exchange Mt. Gox was established. This marks As Bitcoin officially flows into the market. Despite this, the only people who can truly understand and enter the market to participate in Bitcoin buying and selling are geeks who are passionate about Internet technology. They discuss Bitcoin technology on forums, mine Bitcoins on their computers, and then buy and sell Bitcoins on Mt. Gox. Today, these geeks have become billionaires.
3. Market brewing stage: At the beginning of 2013, the price of Bitcoin was US$13. However, on March 18 of the same year, the Cyprus government closed banks and the stock market due to the financial crisis, causing the price of Bitcoin to soar. In April, the highest price rose to US$266. . On August 20 of the same year, the German government confirmed the currency status of Bitcoin. On October 14, the Chinese Internet announced the opening of a Bitcoin payment channel. In November, the U.S. Senate hearing also clarified the legality of Bitcoin. On November 19, the price of Bitcoin It rose to $1,242, forming a new high. Despite this, the foundation for blockchain to enter the mainstream social economy is not yet available, and the surge in Bitcoin prices is only due to overly optimistic expectations. The containment of China's banking system, the collapse of Mt.Gox and other events caused the price of Bitcoin to continue to fall. In early 2015, the price of Bitcoin had fallen below 200 US dollars. From 2013 to early 2015, the public began to understand Bitcoin and blockchain.
4. Blockchain mainstream period: Britain left the EU on June 23, 2016, North Korea’s fifth nuclear test in September, Trump’s election in November and other events. The uncertainty of the world’s mainstream economy has led to risk aversion. Functional Bitcoin began to recover. The market demand was large and the increase in transaction volume caused the price of Bitcoin to soar from a maximum of 400 US dollars in 2016 to 20,000 US dollars in 2017. The wealth-making effect of Bitcoin and the transaction overflow caused by the congestion of the Bitcoin network It has led to the explosion of other series of virtual currencies, and various blockchain applications have also exploded. There have been many blockchain assets that are hundreds of times, even a thousand times, or ten thousand times.It sparked a global craze, and the launch of Bitcoin futures trading on the Chicago Mercantile Exchange marked the official entry of Bitcoin into the mainstream investment product series, and Bitcoin and blockchain have completely entered the global spotlight.
5. Industrial implementation stage: After the market frenzy in 2017, virtual currency and blockchain made adjustments in terms of market, supervision, and cognition in 2018, returning to rationality. Many blockchain projects that imitate blockchain technology in 2017 will gradually die out as the market cools down, and projects with real practical blockchain applications will initially be implemented. 2018 is not only the first year of blockchain, but also a blockchain gold rush period. After the big waves wash away the sand, what remains is relatively good gold.
From the perspective of the history of blockchain development, blockchain technology is not yet mature and is currently in the growth stage. Specific practical applications of blockchain are only used in the financial field. To apply blockchain to other industries, there is still need for There is a journey to go, but the blockchain trend should be grasped. There are advantages and disadvantages in actively learning the new field of blockchain.

⑤ What are the reasons for the emergence and rise of blockchain?

(1) Technical level. Distributed computing has affected technology developers since 2007, so the emergence of distributed autonomous Bitcoin in the field of virtual currency is also a normal phenomenon.

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

(3) Commercial level. The three major characteristics of blockchain, namely decentralization, trustlessness, and extreme difficulty in counterfeiting, exactly solve the need to reduce the trust cost of both parties and speed up transactions in financial fields such as stock trading and bank settlement.

(4) Political level. Blockchain can reduce transaction costs to a certain extent, but the anonymous and untraceable nature of blockchain brings huge political risks.

[Blockchain was proposed as the underlying technology of Bitcoin at the end of 2008]

⑥ What does blockchain mean and how to understand it

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of related data generated using cryptography methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

Notes

1. Blockchain originated from Bitcoin in November 2008 On March 1, a person claiming to be Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on P2P network technology, encryption technology, timestamp technology, blockchain technology, etc. electronic cashThe architectural concept of the system marks the birth of Bitcoin.

Two months later, the theory came into practice, and on January 3, 2009, the first genesis block with serial number 0 was born. A few days later, block number 1 appeared on January 9, 2009, and was connected to the genesis block number 0 to form a chain, marking the birth of the blockchain.

2. In order to realize the great leap forward development of blockchain finance, in order to promote the new development of China’s economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that generations have been striving for, Puyin Group launched the On the 9th, a Puyin Blockchain Finance Guiyang Strategy Release Ceremony was held in Guizhou. At the meeting, the digital circulation of assets through blockchain, the blockchain financial transaction model, and the application of blockchain services and social public industries will be discussed. Explore.

⑦ What is the development process of blockchain applications?

The development process of blockchain can be divided into three stages. Melanie Swann, founder of the Blockchain Science Institute, in her book "Blockchain: A New Economic Blueprint and Introduction", divides the application development of blockchain into three stages: Blockchain Chains 1.0, 2.0 and 3.0.

1. Blockchain 1.0 Cryptocurrency Era (2008-2013)

In 2008, Satoshi Nakamoto first proposed the concepts of Bitcoin and blockchain. In January 2009, the first blockchain was launched. At this stage, people are paying more attention to cryptocurrency transactions, and blockchain is only the underlying technology, acting as a "public ledger".

2. Blockchain 2.0 Smart Contract Era (2014-2017)

In 2014, "Blockchain 2.0" became synonymous with decentralized blockchain databases. At this stage, people mainly focus on the application of the platform. Anyone can upload and execute smart contracts on the blockchain, and will automatically receive rewards after execution. Since this transaction process does not require any intermediary, people's privacy is greatly protected.

3. Blockchain 3.0 Large-Scale Application Era (2018-)

At this stage, people began to build a completely decentralized data network. Blockchain technology Applications are no longer limited to the economic field, but have expanded to art, law, real estate, hospitals, human resources and other fields.
