⑴ What is a milestone in the development of blockchain

1. Satoshi Nakamoto’s paper-Bitcoin White Paper

In 2008, it was too loose in the United States Under the credit standards, the huge bubble created by housing loans triggered a series of financial crises that started in September 2008.

On Sunday, September 14, Lehman Brothers declared bankruptcy after the U.S. Federal Reserve refused to provide a financial support aid, and on the same day Merrill Lynch announced that it was acquired by Bank of America. These two events marked the starting point of the financial crisis, which in turn triggered the global stock market crash and the Great Financial Recession. Many investors suffered heavy losses and made people begin to distrust the totalitarian financial system.

2. Genesis Block

2009 On January 3, 2018, the first Bitcoin block was born after the first batch of miners obtained 50 Bitcoins through mining. This also marked the official birth of the Bitcoin financial system. But interestingly, in Bitcoin Several years after the advent of blockchain, people discovered a hexadecimal string in line #1616 of Coinbase’s genesis block transaction code.

After converting this string into alphanumeric characters, you will get "sknab rof tuoliab dnoces fo knirb no rollecnahC 9002/naJ/30 semiT ehT". The reverse reading is "The Times 03/Jan/2009" Chancellor on brink of second lout for banks” is the founding date of Bitcoin and the message left by Satoshi Nakamoto in the original transaction.

3. The first Bitcoin payment – ​​PizzaDay

Laszlo Hanyecz is a Floridian and engineer working at the online retail company GoRuck, but if you are in the currency circle, you You must have heard some of his amazing deeds: Hanyecz used 10,000 Bitcoins (BTC) to buy two slices of pizza from Papa John's from netizens on May 22, 2010, which is a $25 pizza. Today, 10,000 Bitcoins are worth approximately for US$40 million.

The man named Jeremy Sturdivant (online name "Jercos") was the person who originally received 10,000 Bitcoins in exchange for two slices of pizza to Hanyecz. The importance of this transaction is that this is the first time in history that Bitcoin has been physically traded, proving that Bitcoin does have the function of price transfer in the real world.

4. Mt. Gox, the largest exchange hacking incident in history

On February 24, 2014, Mt. Gox was the largest Bitcoin exchange at the time. The exchange’s CEO Mark Karpeles spoke to TribeGe Zhong announced his withdrawal from the Bitcoin Foundation, and subsequent visits to Mt. Gox will only return a blank page.

On February 28, 2014, Mt. Gox filed for bankruptcy protection with the Tokyo District Court. Data from the bankruptcy research institution "Teikoku Databank, Ltd." showed that Mt. Gox was in debt Reaching 6.5 billion yen, the revenue in 2013 was 135 million yen; Imperial Information Research Company stated in a press release that Mt. Gox subsequently discovered that 100,000 of its own Bitcoins and 750,000 user Bitcoins were stolen.

5. The advent of Ethereum

On July 30, 2015, the first Ethereum was officially launched, named Frontier. All the Ethereum promised to early investors was successfully delivered, and developers began to weave their dreams on Ethereum.

Part II—Constantinople of the third version of Ethereum Metropolis will be launched soon (currently postponed to the middle of next year). Although the current price of Ethereum is less than 10% of this year’s high, In the past three years, we have witnessed the innovations that Ethereum has brought to the world: including the Ethereum Virtual Machine, smart contracts, Dapps, permissioned shared ledgers (Permissioned Ledger), etc.

Although Ethereum is facing expansion difficulties and is still waiting for technology updates, in 17 and 18 years, many underlying public chains emerged as application platforms, that is, many competitors of Ethereum, opening up the "multiple "Chain Era". Currently, there are many dApp developers who are turning to other public chains due to the limitations of Ethereum's current TPS. Some people believe that the future will be a scenario of "multiple chains in parallel, each chain facing one aspect."

⑵ What are the six major stages of blockchain use case development

Blockchain is a point-to-point digital distributed ledger that records all transactions and information that occur in the peer-to-peer network. It cannot be tampered with, only appended. The following are the six major stages of blockchain use case development analyzed by Jinwowo Network Technology:
Analyze services and processes → Define technical blueprint → Develop concepts → Policy and regulatory framework → Develop pilot → Scale

< p>⑶ The birth history of blockchain

Many people will be instinctively intimidated when they hear the three words "blockchain", thinking that it is an inscrutable content or a technology that is not related to I don’t have a dime of connections.

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 asIf you own a computer or a mobile phone, you are closely connected to the entire world. Elites are accustomed to calling the past Internet era 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 currency issued by the government. Once the company that backs the virtual currency goes bankrupt or the central server of the general ledger is hackedIf it is breached, this virtual currency will face the risk of collapse. Satoshi Nakamoto optimized David Chaum's Ecash, integrating timestamps, proof-of-work mechanisms, asymmetric encryption technology, and the structure of UTSO, and ultimately 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.

⑷ The development of blockchain applications has gone through several stages

Principles of blockchain technology

By definition, blockchain is a time-based It is a traceable chain data structure that combines continuously generated information blocks in a sequential manner. It is a distributed ledger that cryptographically ensures that data cannot be tampered with or forged.

Blockchain is an innovative application formed by combining asymmetric encryption algorithms, consensus mechanisms, distributed storage, point-to-point transmission and other related technologies in new ways. The biggest advantage and direction of blockchain technology is "decentralization". By using cryptography, consensus mechanisms, game theory and other technologies and methods, decentralized credit-based decentralization can be realized in a distributed system where network nodes do not need to trust each other. Peer-to-peer trading.

The excellent characteristics of blockchain come from its unique technical foundation. A basic blockchain must at least consist of three parts: data layer, network layer and consensus layer.

The data layer provides a unique data structure to ensure security, and uses asymmetric encryption, hash function, Merkle tree and other technologies to encrypt data to ensure data security and provide the basis for blockchain applications;

p>

The network layer realizes the core idea of ​​decentralization through the P2P network. In the BitTorrent network, each node is both a data receiver and a data sender.

In blockchain technology, the public key is similar to a seed. With the public key, you have an identity that can speak in the network. At present, the consensus mechanisms mainly include PoW, PoS and DPoS consensus mechanisms. If you want to attack the blockchain, you must provide greater computing power than Zhu Lian. The benefits obtained are far less than the cost of the attack. The PoW consensus mechanism competes through computing power. Ensure the security and decentralization of the system.

⑸ 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 technologiesTechnology, intended to create 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 sign 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 and the collapse of Mt. Gox caused the price of Bitcoin to continue to fall. In early 2015, the price of Bitcoin had fallen below $200. 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.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.

⑹ How is the development of the blockchain market

Blockchain definition

According to the definition in the "Blockchain White Paper (2019)" of China Academy of Information and Communications Technology: Blockchain is an accounting technology that is jointly maintained by multiple parties, uses cryptography to ensure transmission and access security, and can achieve consistent data storage, difficulty in tampering, and prevention of repudiation; in the "Security of Financial Distributed Ledger Technology" of the People's Bank of China "Specification" defines: Distributed ledger technology is a distributed infrastructure and computing paradigm formed by the highly integrated integration of multiple core technology systems such as cryptographic algorithms, consensus mechanisms, point-to-point communication protocols, and distributed storage.

Blockchain technology collectively maintains trusted database technology in a decentralized manner. It has the characteristics of decentralization, tamper-proof, and high scalability. It is working closely with big data, cloud computing, artificial intelligence, 5G, etc. The new generation of information technology is rapidly integrated and applied to various important fields such as government affairs, medical care, charity, and judicial governance. It is expected to promote mankind from the information Internet era to the value Internet era.

Blockchain development stages

In the past ten years, blockchain technology has been continuously upgraded. The industry has divided its evolution and development into three stages. These three stages are not realized sequentially. It is a process of common development and mutual promotion.

The blockchain industry will be further standardized in 2020

In 2020, my country's blockchain policies will continue to be favorable, standards and regulations will be more perfect, industry scale will continue to grow, technology will continue to innovate and develop, and application demonstration effects in key areas will accelerate. At the same time, based on the problems existing in my country's blockchain development in 2019, CCID Blockchain Research Institute proposed to speed up top-level design and formulation, establish a sound regulatory system, accelerate core technology innovation and research and development, promote third-party evaluation and certification, strengthen professional talent training, and accelerate promotion Six suggestions for implementation in various fields.

——The above data comes from the "China Blockchain Industry Market Foresight and Investment Strategic Planning Analysis Report" by the Qianzhan Industry Research Institute.

⑺ Do you know the three important stages in the history of blockchain development?

As blockchain technology matures, blockchain technology has achieved significant results in the financial field. 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 have been important developments and inventions at every stage of blockchain technology, and blockchain technology has only existed for a small portion of the Internet's time, so there are likely still important developments to come.

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 Creating opportunities,It also drives related developments. 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.

⑻ 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 Lead 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.

⑼ Development of blockchain technology

To understand the development of blockchain technology, first of all, everyone needs to understand what blockchain is.

Blockchain is actually not difficult to understand. “Blockchain” is a term in the field of information technology. In essence, it is a data transmission method like the Internet. It’s just that the blockchain has been upgraded and innovated, and has integrated many new technologies, such as cryptography, distributed storage, smart contracts, consensus algorithms, etc., giving it unique advantages.

It can also be regarded as a cluster database. The information and data stored in it have the characteristics of "unforgeable", "full traces", "traceable", "open and transparent", "collective maintenance", etc. feature. Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.

Although blockchain originated from Bitcoin, in essence, blockchain is also one of these Internet protocols. It can be said to be a new innovation for existing Internet protocols. method of data transmission. Its advantage is that it can use data transmission as the basis to change the existing traditional third-party-centered trust endorsement model.

The unique thing about blockchain is its decentralization. This is also the most important feature of blockchain. The so-calledDecentralization means removing the center so that the rights originally belonging to the centralized role are decentralized and users can freely conduct peer-to-peer transactions.

⑽ Blockchain Encyclopedia: The Past and Present of Blockchain - 3.0 Era

The representative of the blockchain 1.0 era is Bitcoin, the representative of the 2.0 era is Ethereum, and The chaotic era of various copycats and air coins. Blockchain 3.0 is the era of consumer-level blockchain that has truly entered commercial and physical applications after the troubled times. The typical symbol 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. Break the traditional enterprise organizational hierarchy and form a self-organizing formIt 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 thereby 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-commerce is a self-organized community of blockchain. Every consumer is a token owner 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.
