区块链的由来历史,区块链的来龙去脉

1. What is the development history of blockchain technology?

Which came first, Bitcoin or blockchain? When Bitcoin was first born, there was no concept of "blockchain". People used bitcoin (lowercase b) to represent Bitcoin, and Bitcoin (capital B) to represent its underlying technology, which is what we now call blockchain technology. In 2015, after The Economist published its cover article "Blockchain Technology Reshaping the World," blockchain technology set off a financial technology craze around the world. Major financial institutions and banks around the world rushed to study blockchain technology. In 2016 alone, billions of dollars were invested in blockchain-related companies. In September 2017, the Chinese government website (www.gov.cn) published an article "my country's blockchain industry is expected to be at the forefront of the world", publicly supporting the development of blockchain technology and popularizing blockchain technology to 1.3 billion Chinese people . The application of blockchain in real economic fields such as finance, insurance, retail, and notarization has begun to accelerate.

2. Who is the inventor of blockchain?

1. In 2008, Satoshi Nakamoto proposed the concept of blockchain for the first time. Over the past few years, blockchain has become a core component of the electronic currency Bitcoin: serving as the public ledger of all transactions.

2. By utilizing peer-to-peer networks and distributed timestamp servers, blockchain databases can be managed autonomously. The blockchain invented for Bitcoin makes it the first digital currency to solve the problem of repeated consumption. Bitcoin's design has become a source of inspiration for other applications.

3. What is the popular explanation of blockchain? Did blockchain originate from Bitcoin?

1. Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust", created a reliable "cooperation" mechanism, and has broad application prospects.

2. Blockchain originated from Bitcoin. On November 1, 2008, a person calling himself Satoshi Nakamoto published "Bitcoin: A Peer-to-Peer Electronic Cash System" "The article explains the architectural concept of an electronic cash system based on P2P network technology, encryption technology, timestamp technology, blockchain technology, etc., which 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.

4. Blockchain Encyclopedia: The Past and Present of Blockchain - 3.0 Era

The representative of the blockchain 1.0 era is Bitcoin, and the representative of the 2.0 era is Ethereum. And the troubled times of various copycats and air coins. Blockchain 3.0 is a consumer-level blockchain that has truly entered commercial and physical applications after the chaos.A typical symbol of this era is the emergence of tokens. The pass has brought about changes in traditional business models and production relations. The pass has moved from the digital world to the real economy and has begun to seek practical applications in various industries.

The pass has three elements, one of which is indispensable.

Pass: The pass can be circulated on a large scale in a network and can be verified anytime and anywhere; Certificate: As a proof of digital rights and interests, the pass must be a certificate of rights and interests that exists in digital form, and it must represent It is a right, an inherent and intrinsic value; value: the token must have economic value.

In this way, the meaning of "token economy" is not difficult to understand. The token economy is a large-scale group collaboration based on tokens. It maximizes the role of tokens, allows every role that creates value to share value fairly, fully mobilizes participation motivation, and forms a self-organizing form.

Major changes in the blockchain 3.0 era

The token economy has laid the theoretical basis and technical support for the large-scale application of blockchain, and the future world will also be transformed by it. Large-scale changes include:

1. Fragmented investment, fragmented income, subverting the traditional way of doing business on the Internet. In the traditional Internet era, it was impossible for ordinary people to participate in the investment of a company, but the emergence of blockchain allows ordinary people to make fragmented investments in a large asset. Assuming that Alibaba originally adopted blockchain for fragmented investment, then all fragmented shareholders who invested in Alibaba would be able to reap a return on investment that has increased thousands of times today!

2. Break the money-burning model of the Internet and make everyone a winner. The free model of the traditional Internet is essentially to obtain a large number of users through free products to form monopolies and barriers, and then make profits through advertising and value-added services on this basis. In the blockchain 3.0 era, project income is redistributed by issuing tokens to attract more early investors and community users. As the number of users holding tokens increases, the value of the tokens will become higher and higher, and community users, investors, and projects can all benefit from it. In this way, the money-burning model of providing free services in the early days of the traditional Internet can also be improved, and everyone will become a winner.

3. Breaking down the traditional corporate organizational hierarchy, self-organization may become a future trend. In the blockchain 3.0 era, through the establishment of distribution and collaboration mechanisms through smart contracts, it can be more efficient and accurate than enterprises. All token owners will naturally form a community. Everyone has the same goal - "to promote the development of the project and make it a success". They are all members of the community, contribute to the community, promote the value-added of the token, and thus gain benefits together. profit. From a philosophical perspective, this new self-organizing community of freedom, independence, and equality must be the future trend. Gojoy blockchain e-commerceIt is a blockchain self-organized community. Every consumer is the owner of its token and a fragmented investor, so he is very happy to co-create and build Gojoy value.

Therefore, we can look forward to the era of great development of the blockchain 3.0 token economy, and the existing ones may be subverted. What we need to be prepared for is to work hard to embrace the blockchain. If you want to seize the trend of blockchain and understand how to transform into blockchain, please leave a message to communicate and we will take you to learn the blockchain professional certification course.

5. 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 with the pseudonym Satoshi Nakamoto first described a new fantasy report on electronic currency on a cryptography discussion group in 2008 under a different name. Since then, Bitcoin has been 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 the Chinese banking system, the collapse of Mt. Gox and other events have caused Bitcoin toThe price continued 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 a hundred times, even a thousand times, or ten thousand times, triggering a crazy pursuit around the world, and then Chicago The launch of Bitcoin futures trading on the commodity exchange marks Bitcoin’s official entry 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.

6. Who proposed the idea of ​​blockchain

Satoshi Nakamoto (English: Satoshi Nakamoto), who claims to be Japanese-American, is often translated as Philosophy of Nakamoto by Japanese media. This person is the creator of the Bitcoin protocol and its related software Bitcoin-Qt, but his true identity is unknown. Satoshi Nakamoto published a paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System" in 2008, describing a method he called "Bitcoin." "Coin" electronic currency and its algorithm. In 2009, he released the first Bitcoin software and officially launched the Bitcoin financial system. In 2010, he gradually faded away and handed the project over to other members of the Bitcoin community. Satoshi Nakamoto is believed to hold approximately one million Bitcoins.

7. How the blockchain was formed

The origin of the blockchain comes from Satoshi Nakamoto in 2008. Based on this ideological concept, the first product "Bitcoin" was born . The origins of blockchain technology are often attributed solely to a few godsThe actions of secret geniuses who work under the pseudonym Satoshi Nakamoto. This view of history often makes the technology seem almost magical and difficult to understand. It's even more fundamental when one understands the actual history behind the development of these systems. In this section, I will outline the most important topics from the decades of research on consensus algorithms and distributed systems that led to the creation of blockchains.

8. 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.

9. The History of the Birth of Blockchain

Many people will be instinctively intimidated when they hear the word "blockchain" and think it is unfathomable content. Or a technology that has nothing to do with me.

2018 is the first year of blockchain technology. In the past Spring Festival, blockchain has become really popular. The "three o'clock sleepless zone" of the first blockchain community "Blockchain", articles from major media "How to introduce blockchain to seven aunts and eight aunts", novices from all walks of life are ready to enter the currency circle and try their best, etc.

We know that the Internet has connected the world over the course of decades. People don’t talk about whether the world is flat, because as long as you have a computer or a mobile phone, you are closely connected to the entire world. Elites are used to putting past InternetThe Internet era is called the information Internet era.

With the advent of blockchain technology in 2008, humans were caught off guard and drawn into the world of bits. In the future, no matter whether you understand whether you know what blockchain technology is? Do you understand how digital virtual currency is implemented? They have all been coerced into the second era of the Internet: the era of value Internet. What you don’t know is how blockchain technology was born?

David Chaum, the "bishop" figure of cypherpunk in the 1980s and 1990s, invented the cryptographic anonymous cash system Ecash in 1990. Chaum believes that a distributed, truly digital cash system should encrypt people’s privacy.

British cryptographer Adam Baker invented Hashcash in 1997, which used the Proof of Work system. The proof-of-work system is one of the core concepts of Bitcoin.

In 1997, Harper and Stonitta proposed a protocol that uses timestamps to ensure the security of digital files. This protocol has also become one of the prototypes of the Bitcoin blockchain protocol. The biggest feature of timestamps is that when a virtual currency is traded, it is timestamped and it cannot be changed.

Cryptozoology expert Dai Wei invented B-money in 1998. B-money emphasizes point-to-point transactions and immutable transaction records, and every trader in the network keeps track of transactions.

In 2004, Hal Finney, a top developer at PGP Crypto Company, launched the electronic currency "Crypto Cash", which used a reusable proof-of-work mechanism (RPOW).

But their single invention and idea are still not enough to become a world-class virtual currency. Ecash declared bankruptcy in 1998; the proof-of-work system cannot guarantee whether digital currencies have been traded many times; the technical protocol of timestamps is only used on a small scale by the government; in the B.money system, David did not solve the problem of ledger synchronization; finally Halfini's idea is still not enough to become a world-class virtual currency.

In 2008, when all technical conditions were mature and time conditions were mature, a god-level figure was still needed to answer a question: why did the previous virtual currency pioneers fail? The name of the person who answered this question is Satoshi Nakamoto.

He believes that the most important reason for the failure of previous virtual currencies is that they all have a centralized structure, and all transaction data will be aggregated into the company's data center, which is no different from government-issued currencies. Once the company that backs the virtual currency goes bankrupt, or the central server of the general ledger is compromised by hackers, the virtual currency will face the risk of collapse. Satoshi Nakamoto’s review of David Chaum’s EcashAfter optimization, he integrated timestamps, workload proof mechanisms, asymmetric encryption technology, and the structure of UTSO, and finally he invented Bitcoin.

It can be seen that blockchain is not a single technology, it is a collection of a series of above-mentioned technologies. Bitcoin is just a typical example of the first large-scale application of blockchain technology. In the future, blockchain technology can be applied to many fields such as financial services and social life.
