1. What does blockchain mean and how to understand it

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

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, on November 1, 2008, 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, The architectural concepts of electronic cash systems such as timestamp technology and blockchain technology mark 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.

2. What exactly is blockchain

What is blockchain?
Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system [1].
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
Blockchain was born from Satoshi Nakamoto’s Bitcoin. Since 2009, various Bitcoin-like digital currencies have appeared, all based on public blockchains.
The current situation of digital currencies is that a hundred flowers are blooming. List some common ones: bitcoin, litecoin, dogecoin, dashcoinIn addition to currency applications, there are also various derivative applications, such as underlying application development platforms such as Ethereum and Asch, as well as industry applications such as NXT, SIA, BitShares, MaidSafe, and Ripple.
On January 20, 2016, the People’s Bank of China Digital Currency Seminar announced that it had achieved phased results in digital currency research. The meeting affirmed the value of digital currency in reducing the issuance of traditional currency and stated that the central bank is exploring the issuance of digital currency. The expression of the People’s Bank of China’s Digital Currency Seminar has greatly enhanced the confidence of the digital currency industry. This is the first time that the five central bank ministries and commissions have expressed a clear attitude towards digital currencies since they issued a notice on preventing Bitcoin risks on December 5, 2013. [4]
On December 20, 2016, the Digital Currency Alliance - China FinTech Digital Currency Alliance and FinTech Research Institute were officially established, with Huobi being one of the co-initiators. [5]
Some areas where blockchain can be used are:
▪ Smart contracts
▪ Securities trading
▪ E-commerce
▪ Internet of Things
▪ Social communication
▪ File storage
▪ Proof of existence
▪ Identity verification
▪ Equity crowdfunding
We can compare the development of blockchain to the development of the Internet itself , something called finance-internet will be formed on the Internet in the future, and this thing is based on blockchain, and its precursor is bitcoin, that is, traditional finance starts from private chains and industry chains (local area network), and the bitcoin series starts from public chains (Wide Area Network), they all express the same concept - digital assets (Digital Asset), and finally converge to an intermediate balance point.
The evolution of blockchain is:
▪ Blockchain 1.0 - digital currency
▪ Blockchain 2.0 - digital assets and smart contracts
▪ Blockchain 3.0 ——The implementation of distributed applications in various industries
Blockchain is divided into three categories, which is introduced in detail in the book "Blockchain: Defining the New Pattern of Future Finance and Economics" [2] issued by Currency, < br />Hybrid blockchains and private blockchains can be considered as broad private chains:
Public Blockchains (PublicBlockChains)
Public blockchains refer to: any individual or group in the world Transactions can be sent and effectively confirmed by the blockchain, and anyone can participate in its consensus process. Public blockchain is the earliest blockchain and the most widely used blockchain.The virtual digital currencies of the bitcoins series are all based on public blockchains. There is only one blockchain corresponding to this currency in the world.
Consortium (Industry) Blockchain (ConsortiumBlockChains)
Industry Blockchain: Multiple preselected nodes are designated within a certain group as bookkeepers, and the generation of each block is jointly performed by all preselected nodes. Decision (pre-selected nodes to participate in the consensus process), other access nodes can participate in transactions, but do not participate in the accounting process (essentially still managed accounting, just become distributed accounting, how many pre-selected nodes, how to determine the number of each block The bookkeeper becomes the main risk point of the blockchain), and anyone else can conduct limited queries through the open API of the blockchain.
Private Blockchain (privateBlockChains)
Private Blockchain: Only uses the general ledger technology of the blockchain for accounting. It can be a company or an individual, and has exclusive access to the writing of the blockchain. With access permissions, this chain is not much different from other distributed storage solutions. (Dec2015) Conservative giants (traditional finance) all want to experiment with private blockchains, while public chain applications such as Bitcoin have been industrialized, and private chain application products are still being explored.

3. What exactly is blockchain

From the perspective of its application, blockchain is a distributed shared ledger and database with decentralization , the file cannot be tampered with, leaves traces throughout the process, can be traced, is collectively maintained, and is open and transparent. 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 Difficulty

4. What is the origin of blockchain

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

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.

In recent years, the world’s attitude towards Bitcoin has been ups and downs, but as one of the underlying technologies of Bitcoin,Blockchain technology is receiving increasing attention. In the formation process of Bitcoin, blocks are storage units one by one, recording all communication information of each block node within a certain period of time.

The links between each block are realized through random hashing (also called hash algorithm). The latter block contains the hash value of the previous block. With the expansion of information exchange, a block Continuing with one block, the result is called a blockchain.

(4) Blockchain 2009 Extended Reading:

Characteristics of blockchain:

1. Decentralization. Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes self-verification, transmission and management of information through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain.

2. Openness. The foundation of blockchain technology is open source. In addition to the private information of the transaction parties being encrypted, the data of the blockchain is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface. Therefore, the entire System information is highly transparent.

3. Independence. Based on consensus specifications and protocols (similar to various mathematical algorithms such as the hash algorithm used by Bitcoin), 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 the need for any human intervention.

4. Security. As long as you cannot control 51% of all data nodes, you cannot manipulate and modify network data at will. This makes the blockchain itself relatively safe and avoids subjective and artificial data changes.

5. Anonymity. Unless required by legal regulations, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transfer can be carried out anonymously.

5. The first birth time of the blockchain

If it refers to the first mined block, then it was January 3, 2009, when Satoshi Nakamoto The first block, the so-called "genesis block", was mined on a small server in Helsinki, the Netherlands. For information about blockchain, you can learn about it at Crypto Finance mimacaijing.

6. 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.

7. 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. . August 20 of the same yearOn October 14, 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 rose to 1,242 US dollars. , 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 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.
