New era of blockchain
1. Germination stage: the real germination stage of blockchain was from 2007 to 2009. In 2008, a Japanese American with the pseudonym of Nakamoto first expounded a new fantasy report on electronic money in the form of a synonym on the cryptography discussion group, and bitcoin came out. As early as 2007, Nakamoto began to explore a series of new technologies to create a new currency. On October 31, 2008, bitcoin white paper was released, and on January 3, 2009, bitcoin system officially began to operate
the main technologies supporting bitcoin system include hash function, distributed ledger, blockchain and asymmetric encryption; It can be seen that these technologies build the initial version of the blockchain, and it can also be said that the blockchain is the underlying technology of bitcoin. During the three years from 2007 to 2009, bitcoin was an experimental stage in which a very small number of people participated, and the real commercial activities had not really started
2. "Geek" niche stage: here, "geek" refers to people who are crazy about Internet technology and take technological innovation as fashion and life. On February 6, 2010, the first exchange of bitcoin appeared. On May 22 of the same year, someone bought two hamburgers with 10000 bitcoins. On July 17 of the same year, the exchange Mt. GOx was established, marking the official inflow of bitcoin into the market. Nevertheless, the only people who can really understand and enter the market to participate in bitcoin trading are geeks who are keen on Internet technology. They discuss bitcoin technology on the forum, mine for bitcoin on their own computers, and then buy and sell bitcoin on Mt. GOx. Now these geeks have become billionaires
3. Market brewing stage: the price of bitcoin was $13 at the beginning of 2013, but on March 18 of the same year, the government of Cyprus closed the bank and stock market e to the financial crisis, which made the price of bitcoin soar, and the highest price rose to $266 in April. On August 20 of the same year, the German government confirmed the currency status of bitcoin. On October 14, China network announced the opening of bitcoin payment channel. In November, the US Senate hearing also confirmed the legitimacy of bitcoin. On November 19, the price of bitcoin rose to US $1242, forming a new high. Nevertheless, the foundation for blockchain to enter the mainstream social economy is not yet available, and the soaring price of bitcoin is only e to over optimistic expectations. The containment of China's banking system, the collapse of Mt. GOx and other events made the price of bitcoin continue to fall. At the beginning of 2015, the price of bitcoin has dropped below $200. From 2013 to the beginning of 2015, the public began to understand bitcoin and blockchain
4. The mainstream period of blockchain: on June 23, 2016, the United Kingdom left the European Union, the fifth nuclear test of North Korea in September, Trump's election in November and other events, the uncertainty of the world's mainstream economy led to the recovery of bitcoin with the function of risk aversion. The market demand was large, and the increase of trading volume made the price of bitcoin soar from $400 in 2016 to $20000 in 2017, The wealth effect of bitcoin and the transaction overflow caused by network congestion of bitcoin have led to the outbreak of other series of virtual currencies, as well as a variety of blockchain applications, resulting in the emergence of a large number of blockchain assets that are 100 times, even 1000 times and 10000 times, which has aroused the crazy pursuit of the world, Subsequently, the Chicago Mercantile Exchange launched bitcoin futures trading, marking that bitcoin has officially entered the mainstream investment proct series, and bitcoin and blockchain have entered the global attention
5. Instry landing stage: after the market frenzy in 2017, the virtual currency and blockchain have been adjusted in terms of market, supervision, cognition, etc. in 2018, returning to rationality. In 2017, many blockchain projects that follow the blockchain technology will graally die out with the cooling of the market, and the projects with real blockchain applications will be initially implemented. 2018 is not only the first year of the blockchain, but also a gold rush period for the blockchain. After the 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 period. The specific practical application of blockchain is only used in the financial field. It still needs a long way to go to apply blockchain from other instries. However, we should grasp the trend of blockchain and actively learn from the new field of blockchain.
in today's life, many people use this pretext to cheat, such as direct selling, capital, technology, etc. There is no right or wrong in technology, but in people
with the progress of the times and society, the beginning of the application of any technology will be questioned positively and negatively. However, with the relative application and maturity of technology and the improvement of technology, the various applications around people will continue to improve. I believe that in the near future, these doubts will graally dissipate
the following is a summary of some blockchain scams around us
trap 1: block chain is the coin trap
trap two: virtual currency transactions, promise low investment, high return
trap three: centralization can solve all problems
trap four: block chain extension procts can be laid down with a mining machine to earn money
trap five: WeChat, Alipay trading transactions virtual currency
The first sub chain of ETO public chain, Jingniu chain, is coming online soon, helping the entity enterprises to enter a new era of "blockchain +"
blockchain has been born for more than ten years. In recent years, with the increasingly mature blockchain technology and the continuous enrichment of application scenarios, blockchain has attracted more and more attention. In particular, on April 20 this year, the national development and Reform Commission explicitly proposed for the first time that the blockchain should be included in the scope of China's "new infrastructure". Blockchain has become a key technology to enhance the efficiency of China's stock assets and improve the competitiveness of medium and long-term instries
the significance of chain reform? In essence, through the consistent distribution and rendant storage of data in the whole network, blockchain realizes the openness, transparency and non tampering of data, reces the information asymmetry at the system level, and enables nodes to reorganize business relationships based on new information acquisition capabilities. While the information system of blockchain is decentralized, the overall efficiency is improved by constructing the decentralization of business system and the disintermediation of business process
the essential requirement of real economy reform is to rece cost and increase efficiency. The purpose of developing digital economy is to serve the real economy, and blockchain plays an extremely important role in this process
on the one hand, the so-called "chain reform" is to reconstruct and reorganize the business process of the real economy through the blockchain, and realize the distribution and storage of data on the chain with decentralized business system and disintermediated business process; On the other hand, through the introction of token economy, we can adjust the interest structure of different subjects in the business system, improve the value flow efficiency of the whole supply chain system, and reconstruct the interest distribution model. That's why chain reform is so important
from the technical level, the chain reform can solve the problems of trust, security, privacy protection, cost rection and efficiency through application, information and assets. From the perspective of token economy, chain reform can change the way of economic value output, circulation and distribution, so that all contributors of the whole ecology can get corresponding returns for their own efforts
the chain reform transforms the identity of "consumer" into the identity of "consumer + communicator + investor", transforms the interest pair into the interest community, and improves the stickiness of terminal consumers; Through the design of incentive model, the proction relationship can be liberated, the collaborative value of the upstream and downstream of the supply chain can be improved, and the benefit can be maximized. In the long run, chain reform is of great significance to the development and progress of the whole society and the promotion and protection of personal income
Jingniu chain, which focuses on one-stop chain reform service, is the world's leading one-stop chain reform service platform focusing on real economy chain reform and digital equity of real enterprises. On the one hand, Jingniu chain is committed to help small and medium-sized enterprises solve the internal and external incentive problems through blockchain technology, obtain immediate incentive feedback internally, and improve the efficiency of upstream and downstream collaboration externally; According to the proct characteristics of different enterprises, personalized chain reform scheme is provided to enable enterprises to obtain differentiated competitive advantage
the specific destruction mechanism is as follows: 5% of the amount is always released every day as the destruction pool, and the explosion report mechanism is used to return to the participants. The miner needs 3% equivalent ETO (platform token of ETO equity public chain) as the miner's fee to participate in the explosion report, and the mine pool will get random returns of 2 times, 3 times, 4 times and 5 times according to the destruction amount, The money returned by the miner will be released by 2% of the balance per day until the amount of the destroyed ore pool has been exploded. The amount of money that has not been exploded on that day will be deposited in the destroyed ore pool
in terms of miner's fees, 3% ETO of equivalent value is required for pledge or withdrawal of currency JnL as token, and 0.3% ETO of equivalent value is required for transaction and transfer as handling charge
in addition, 3% of daily proction will be converted into 1% charity fund, 1% Tourism Fund and 1% learning fund respectively
As the world's leading service platform for chain reform and digital equity, Jingniu chain not only has the world's top team, covering the landing cases of chain reform and digital equity service in many instries, but also can provide services such as all-round and multi-channel promotion and operation, investment and merger, digital equity transformation, listing and circulation transaction, JnL, as the circulation medium of the value bearing capacity of the whole ecosystem, plays an important role
in the future, as more and more small and medium-sized entity enterprises realize the importance of blockchain and the continuous development of the chain reform platform represented by Jingniu chain, more "blockchain +" instries will be launched, and the global entity enterprises will enter a new era of "blockchain +"
At present, more than 90% of the issued projects of Shanghai related token financing (ICO) issuance platform have been basically completed, and the relevant bitcoin and other virtual currency trading platforms have also put forward exit plans, and started to carry out the work of customer capital and asset retirement
it is understood that after stopping trading business on September 30, Shanghai will focus on urging all trading platforms to ensure investors to withdraw cash smoothly. Like Beijing, the relevant person in charge of Shanghai mutual fund rectification Office disclosed that in principle, it requires relevant platform executives and other personnel to stay in Shanghai to assist in the removal work
I hope everyone will cooperatein a word, blockchain is decentralized, using the trust protocol between distributed data nodes to achieve data sharing and mining upgrade. Artificial intelligence covers a wide range, including language recognition, image recognition, machine learning, intelligent logic and many other disciplines.
There are e-books of this book, which can be shared with you. How to get the book and look at the pictures
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
domestic coin profit China has introced blockchain into crowdfunding instry, and postal bank has jointly launched an asset custody system based on blockchain with IBM (China) Co., Ltd. This is the first time that China's banking instry has publicly applied blockchain technology to its core business practice.
