Blockchain is the second era of the Internet6

I Will the blockchain become the second era of the Internet?

At present, there is no substantial progress and application of technology, and the factors of hype and bubbles are relatively large.

Ⅱ Talk about several eras of blockchain technology and what are the application prospects

Blockchain 1.0 era
This generation of blockchain technology does not have any application functions , is to issue coins, represented by Bitcoin.
Blockchain 2.0 Era
Blockchain 2.0 is a programmable blockchain.
Blockchain 3.0 Era
Blockchain 3.0 is beyond the financial industry, covering all aspects of social life.

Ⅲ Will this thing really be a post-Internet era?

Yes. In essence, it is a shared database, and the data or information stored in it has the characteristics of “unforgeable”, “full traces”, “traceable”, “open and transparent” and “collective maintenance”. Based on these characteristics, blockchain technology has laid a solid “trust” foundation, created a reliable “cooperation” mechanism, and has broad application prospects.

The foundation of blockchain technology is open source, except that the private information of the transaction parties is encrypted, the data of the blockchain is open to everyone, and anyone can query the blockchain data through the public interface and development of related applications, so the entire system information is highly transparent. As long as 51% of all data nodes cannot be controlled, network data cannot be manipulated and modified arbitrarily, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes. Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. Except for the self-contained blockchain itself, through distributed accounting and storage, each node realizes information self-verification, transmission and management.

IV What are the differences between blockchain and the Internet

Blockchain is essentially a decentralized ledger system, with decentralization, openness, information immutability, Programmable and other characteristics, it can be used as the underlying storage and transmission protocol of the Internet of Value. Blockchain is expected to lead us from personal trust and institutional trust to the era of machine trust. Consensus mechanism is the core of blockchain construction. Digital currency is just the beginning, and the blockchain can change more, reshape the world’s trust system, and solve many problems that cost too much trust in the past.
Blockchain is analogous to the Internet. They have one core difference: the underlying protocol of the blockchain and the Internet and the value of the upper-layer application are completely reversed. Mainly due to two core characteristics of the blockchain:

The first characteristic is that zero-knowledge proof causes the change of data ownership. That is to say, the user’s personal data on the blockchain belongs to the user and does not need to be provided to the application party and stored on the central server. Then the services of the Internet application layer, such as BAT, the core support “data” behind the market value, have lost their original value in the blockchain field.
Another feature is the economic incentive model brought by tokens, which endows the underlying protocol with extremely high value. In the Internet age, no one pays for the http protocol, no one pays for sending and receiving email, and no one pays for Google’s search service.

Ⅳ What stage is the current blockchain development in China?

It is said that this technology is only known in the first city, but it is not widely understood. Not to mention cities. Banks are also preparing to apply blockchain technology but have not really applied it. The financial industry also needs to apply it, but I don’t know when it will be. To be precise, blockchain is only in the initial trial stage in China.

In China, the current industry where blockchain has been applied is network mutual assistance. The network mutual assistance platform I know of, Tongxin Mutual Aid, is the first real application of blockchain in China. Big data technology eliminates the defects of the traditional network mutual aid model and establishes an open and transparent new network mutual aid platform.

You can download their blockchain client to experience it.

VI The trend of the new era, what is blockchain

Blockchain is an important concept of Bitcoin, which is essentially a The centralized database also serves as the underlying technology of Bitcoin. A blockchain is a series of data blocks that are associated using cryptographic methods. Each data block contains the information of a Bitcoin network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
In a narrow sense, blockchain is a chained data structure that combines data blocks in sequential order according to time sequence, and is cryptographically guaranteed to be untamperable and unforgeable distribution. ledger. Broadly speaking, blockchain technology is the use of blockchain data structures to verify and storeData, use distributed node consensus algorithm to generate and update data, use cryptography to ensure the security of data transmission and access, use smart contracts composed of automated script codes to program and manipulate data A brand new distributed infrastructure with computational paradigms.
Biying China introduced the blockchain into the crowdfunding industry. Postal Bank and IBM (China) Co., Ltd. jointly launched a blockchain-based asset custody system. This is the first time that the Chinese banking industry has publicly applied blockchain technology to the core business practices of banks.

VII Is blockchain the trend of the next decade?

Blockchain is the biggest trend of the next decade!
If you look at problems with the thinking of 30 years ago, you will think that everyone else is crazy, but you are actually out of date.
The concept of blockchain can be traced back to the end of 2008. A mysterious person named “Satoshi Nakamoto” published a paper “Bitcoin: A Peer-to-Peer Electronic Cash System” in the forum. , proposed the concept of blockchain for the first time.
On January 3, 2009, the first block of the blockchain was born, and this block is called the “founding block”.
Almost with the birth of blockchain technology, Bitcoin became the first thing to play its role. In the following years, Bitcoin gradually became popular all over the world. In 2017, its crazy market made blockchain technology an important known to all.
The idea of ​​blockchain (blockchain) first appeared in the famous Bitcoin (Bitcoin) open source project. During the birth and development of the Bitcoin project, it has drawn on technical achievements from digital currency, cryptography, game theory, distributed systems, cybernetics and other fields. The blockchain technology is a remarkable innovation.
Blockchain is a distributed database system participated by different nodes, and it is an open ledger system.
Three characteristics of blockchain
Compared with traditional centralized solutions, blockchain technology mainly has the following three characteristics:
The core idea of ​​blockchain is decentralization
br />In the blockchain system, the rights and obligations of any node are equal, and all nodes have the ability to vote with computing power, thus ensuring that the recognized result is the result recognized by more than half of the nodes. Even if it is severely attacked by hackers, as long as the number of nodes controlled by hackers does not exceed half of the total number of nodes in the world, the system can still operate normally, and the data will not be tampered with.
The biggest disruption of blockchain is the establishment of credit
In theory, blockchain technology can make WeChat payment and Alipay no longer have value. The Economist makes an image metaphor for the blockchain: Simply put, it is “a machine that creates trust.” Blockchain enables people to collaborate with each other without trusting each other and without a neutral central authority. Fighting counterfeit money and financial fraud will no longer be needed.
The collective maintenance of the blockchain can reduce the cost
Under the centralized network system, the maintenance and operation of the system depend on the operation and operation of the data center and other platforms, and the cost cannot be omitted. The nodes of the blockchain can be participated by anyone, and each node also verifies the correctness of the results recorded by other nodes while participating in the record, which improves the maintenance efficiency and reduces the cost.
In one sentence, what the blockchain touches is money, trust and power, the fundamental foundations on which human beings live.
Its development has gone through 3 stages
1. Pregnancy period: From 2009 to 2012, the economic form is dominated by Bitcoin and its industrial ecology.
2. Germination period: The period is from 2012 to 2015, when the blockchain entered the public eye with Bitcoin, new wallet payment and remittance companies appeared, and the blockchain economy spread to the financial field. The underlying technology of the blockchain is constantly innovating. Blockchain technology is spun off from the Bitcoin system.
3. Development period: In 2016, we began to explore industry applications, and a large number of blockchain startups appeared. The popularity of ICOs in 2017 brought unprecedented attention to blockchain.
“Blockchain 2.0 Era” is coming
The application service layer is the driving force for the sustainable development of the blockchain, which is divided into three stages of application: 1.0, 2.0, and 3.0.
Programmable currency: Blockchain 1.0 application
Programmable currency, that is, digital currency represented by bitcoin, but it is not the legal currency of any country and region, and no government authority provides it guarantee.
Programmable Finance: Blockchain 2.0 Applications
Blockchain 2.0 applications add the concept of \”smart contracts\” (using program algorithms to replace human execution contracts). This allows the blockchain to expand from the original currency system to the registration and transfer of equity, claims and property rights, the transaction and execution of securities and financial contracts, and even financial fields such as gaming and anti-counterfeiting.
Programmable Society: Blockchain 3.0 Applications
Blockchain is the priceThe core of the Internet of Value is able to confirm, measure and store property rights for the information and bytes representing value in each Internet. It’s not just about recording transactions in the financial industry, but almost anything of value that can be expressed in code. Its application can be extended to any field in need, and then to the whole society.
At present, blockchain applications have begun to surpass Bitcoin (blockchain 1.0), enter the era of blockchain 1.5, and transition to the financial field (blockchain 2.0).
In the next 3-5 years, blockchain may surpass the financial field and enter the field of social notarization and intelligence (blockchain 3.0), including identity authentication, notarization, arbitration, auditing, domain names, logistics, medical care, In the fields of mail, visa, voting, etc., the scope of application has expanded to the whole society, and blockchain technology may become a bottom-level protocol of \”Internet of Everything\”.
At present, blockchain technology has been recognized by the world, and development has become an inevitable trend. It is accompanied by more people’s attention, “The next 30 years will be the integration of new technologies into all aspects of traditional industries, and the 30 years when human society will be turned upside down, no matter who you are, no matter where you are, all of us All will be part of this great change.”
The status quo is like this, the blockchain has given the post-90s era an opportunity, but if you want to control the blockchain technology, you will not be affected by negative factors. The most important thing is , can only have a clear understanding of it, whether it is a regulator, a researcher, a speculator, or a bystander.
It’s time to devote more of your energy to focus on blockchain technology.
The average annual salary of blockchain positions in my country has reached more than 300,000 yuan, and the annual salary of some enterprises has reached more than 1 million yuan. The monthly salary of fresh graduates in the blockchain industry in Beijing, Shanghai and other places has exceeded 20k! The post-90s generation seizes the dividends of the times, and may become the next Alibaba in the future! If you miss it, you may regret it for ten years.

VIII What stages of blockchain development

Blockchain developed in five stages
1. Germination stage: The real germination stage of blockchain was in 2007 By 2009, a Japanese-American pseudonymous Satoshi Nakamoto first expounded a new fantasy report on electronic money on a cryptography discussion group in a synonymous form in 2008, and Bitcoin was born. As early as 2007, Satoshi Nakamoto began to explore a series of new technologies, aiming to create a new currency. The Bitcoin white paper was released on October 31, 2008, and the Bitcoin system officially began to operate on January 3, 2009.
The main technologies supporting the Bitcoin system include hash functions, distributed ledgers, blockchains, 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. During the three years from 2007 to 2009, Bitcoin was an experimental stage with very few people participating, and real commercial activities had not really begun.
2. The “geek” niche stage: The “geek” here refers to people who are fanatical about Internet technology and who take 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 hamburgers with 10,000 Bitcoins. On July 17 of the same year, the exchange Mt.Gox was established. With Bitcoin officially flowing into the market. Even so, the people who can really understand and enter the market to participate in bitcoin trading are only geeks who are keen on Internet technology. They discuss bitcoin technology on forums, mine bitcoins on their computers, buy and sell bitcoins on Mt.Gox, and these geeks are now billionaires.
3. Market brewing stage: At the beginning of 2013, the price of Bitcoin was 13 US dollars, but on March 18 of the same year, the Cyprus government closed banks and the stock market due to the financial crisis, which made the price of Bitcoin soar, and the highest price in April rose to 266 US dollars . On August 20 of the same year, the German government confirmed the currency status of Bitcoin. On October 14, the Chinese network announced the opening of a Bitcoin payment channel. In November, the US Senate hearing also clarified the legality of Bitcoin. Bitcoin price on November 19 It rose to $1242, forming a new high. Despite this, the foundation for the blockchain to enter the mainstream social economy is not yet available, and the surge in Bitcoin price is only due to overly optimistic expectations. Events such as the containment of the Chinese banking system and the collapse of Mt.Gox have 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 European Union on June 23, 2016, North Korea’s fifth nuclear test in September, and Trump’s election in November. The uncertainty of the world’s mainstream economy makes it a safe haven The functional bitcoin began to recover, the market demand was large, and the increase in transaction volume caused the bitcoin price to soar from a maximum of 400 US dollars in 2016 to 20,000 US dollars in 2017.The enrichment effect of Bitcoin and the transaction overflow caused by the congestion of the Bitcoin network have led to the outbreak of other series of virtual currencies, and various blockchain applications have also exploded. There have been hundreds or even thousands of times. 10,000 times the amount of blockchain assets has triggered a frenzy around the world, and the launch of bitcoin futures trading on the Chicago Mercantile Exchange marks that bitcoin has officially entered the mainstream investment product series, and bitcoin and blockchain have completely entered the global attention.
5. Industrial landing stage: After the market frenzy in 2017, the virtual currency and blockchain in 2018 were adjusted in terms of market, supervision, cognition, etc., and returned to rationality. In 2017, many blockchain projects imitating blockchain technology will gradually die out as the market cools down, and projects with real blockchain applications will initially land. 2018 is not only the first year of blockchain, but also a period of blockchain gold rush. After the big waves wash away the sand, all that remains is better gold.
From the perspective of the development history of blockchain, blockchain technology is not yet mature and is currently in the growth stage. The specific practical application of blockchain is only used in the financial field. In order to apply blockchain from other industries, it is necessary to have There is a long way to go, but the trend of blockchain should be grasped. Actively learning the new field of blockchain has advantages and disadvantages.

IX What is the current development stage of blockchain is

It is a data transmission system that can ensure the absolute accuracy of information records.

Most articles on the market are either too professional or long, or the use cases are too simple to be understood accurately. I hope that within 10 minutes, you can thoroughly understand the concept of blockchain, and establish a visual understanding and accurate understanding in your mind.
