Has blockchain 20 been implemented
There is no doubt that blockchain has development prospects, and the necessary condition for development prospects is to enter the mainstream market
North America blockchain infrastructure the oan (former aion network) founder and CEO Matt spoke published an article entitled "in order to successfully enter the mainstream market, blockchain projects must" eat dog food "in Forbes on July 24, in which Matt mentioned his views on how blockchain should enter the mainstream market - & quot; Eat dog food
in the science and technology circle, there is a jargon called & quot; Eat dog food Dogfood (also known as eating your own dog food) refers to companies using their own procts and becoming users of their own procts. Many high growth companies (such as Microsoft, Facebook, Amazon, apple, Netflix and Google) also test their procts by "eating dog food" or help build credibility“ "Eat dog food" is often used to find and fix bugs, but it has another value: to create reliable use cases for the company's procts
this is worth learning from blockchain projects, because blockchain projects often hold & quot; Once built, they (users) will come naturally, which habitually leaves the responsibility of creating new and interesting blockchain applications to a third party
this attitude is very common, even the well-known blockchain summit consensus 2019 also held a conference entitled & quot; Once built, they (users) will naturally come: to build a global blockchain Center & quot; To discuss how governments around the world can make efforts to attract blockchain projects while balancing regulatory, investment and innovation needs
to be fair, this strategy may be effective for blockchains that only focus on people in the currency circle. For the security token, especially for the exchange represented by the transaction, it makes more sense - "supply creates demand" is the usual idea here, especially considering that the realization of these transactions requires the construction of complex infrastructure
in contrast, "eat dog food" is more likely to be adopted by blockchain project developers who seek mainstream audiences (such as those in financial instry, manufacturing and supply chain, identity management, etc.). If blockchain technology wants to enter these mainstream fields, blockchain companies must first "eat dog food". This can not only clearly prove that blockchain technology is feasible outside the coin circle, but also highlight that blockchain can not only optimize existing use cases, but also create new use cases
and the oan team has been adhering to this concept, and relying on the oan and aion's technology stack built over the years, it has developed a financial technology platform moves for independent workers
Matt said that in the development and development of moves, the team hopes that the relevant functions of the OAN blockchain network can be brought into full play, so it will focus on the following three aspects:
1. How to use the OAN blockchain network to improve the credit efficiency of the proct there are two main considerations to improve credit efficiency: 1) can we use the mechanism of the defi market to rece the cost of capital; 2) Can the blockchain technology be used to increase the external trust in the credit process of moves. Here, moves will form a mechanism of "pooling wisdom", so that everyone can contribute to recing credit risk and increasing the credibility of credit process, and may even develop a micro guarantee mechanism in the future. Therefore, users will be able to participate in the market established by the platform as borrowers, lenders or guarantors
specifically, by connecting moves with the oan network, and with the help of digital asset aion, a relationship of interest consistency is formed between procts and users, so that users can personally experience the success of moves procts and directly participate in the oan, a blockchain network supporting moves
3. How to create the first open system of financial reputation data with moves
this open system may become a substitute for traditional credit scores or related mechanisms. Over the years, banks and financial institutions have been using Equifax, Fico or other similar institutions' scores as risk indicators, and the moves team believes that the procts they are building will be a good start - the beginning of a more perfect and modern financial reputation system. This is a long-term goal
moves supports North American mainstream carpooling, take out and other casual work economic platforms, and will be the flagship open application developed by the oan on its blockchain network. In June, moves expanded its operations from Ontario to Alberta and British Columbia into western Canada
all the initiatives of the oan team adhere to the spirit of "eating dog food" and strive to make blockchain technology enter the mainstream market as soon as possible. Blockchain is not for the minority, but for the mainstream. In addition to the oan team, many projects and institutions in the blockchain instry are also aiming at this goal. Can you say that such an excellent and targeted blockchain has no development prospects
The hottest things this year are "bitcoin", "Ethereum" and all kinds of cryptocurrencies, so hot that even aunts and uncles are about to start talking about them. It is no exaggeration to say that 2017 is the first year of the development of cryptocurrency and blockchain technology
as the underlying technology behind bitcoin, the concept of blockchain has only been mentioned in the past two or three years, although as early as 2009, "Nakamoto Tsung" released bitcoin. After this wave of digital currency boom, the concept of blockchain technology has really entered the eyes of all walks of life. I'm afraid it's too early to mention the wide application of blockchain technology, which is still in a very early stage of development. However, e to the arrival of the boom, many technicians and teams have contributed their efforts to build some blockchain concept projects“ Needless to say, as the first application of blockchain technology, bitcoin of "Zhongben cong" has realized the function of distributed ledger, which can realize the first decentralized value transmission of human beings. It can be said that it is "blockchain 1.0". Then Ethereum invented the smart contract, which extended the function of blockchain technology to build applications. It is well deserved to be defined as "blockchain 2.0". However, the blockchain concept projects that came out later did not realize this leap forward role, but only improved to a certain extent at the application level, so they can not be called "blockchain 3.0"
so what is "blockchain 3.0"? Maybe bitcoin OS is the answer: an operation system that is completely based on blockchain technology and follows the concept of blockchain technology. In the 1980s, before Microsoft released the windows operating system, personal computers and Internet technology were still in a non systematic state and could not be popularized. After the release, personal computers were allowed to enter ordinary people's homes, making PC and Internet universal application procts. Recently, bitcoin OS team announced the implementation of the bifurcations of bitcoin and Ethereum on Christmas day, so as to officially publish the plan of developing blockchain OS
anyone who knows a little bit about blockchain technology knows that bitcoin solves the problem of account book, while Ethereum is a smart contract to realize application expansion. Later, a team will launch a distributed storage project. But these systems with only a single functional mole are not "operating systems". The traditional definition of operating system is a huge management and control program, which includes five management functions: process and processor management, job management, storage management, device management and file management. In fact, the OS based on blockchain does not need to change all the five functional blocks into distributed ones, as long as the parts related to the external transmission of value and information can be decentralized and distributed. Therefore, the blockchain operating system should have at least three functions of "account system management, computing resource management and storage resource management", which can realize distributed ledger, edge computing and edge storage. Although it is still too early to define the instry standard in this way, bitcoin OS team is committed to realizing the blockchain OS possessed by these three functional blocks first, and then improving it through iteration
according to the bitcoin OS team, the name "bitcoin OS" is actually "blockchain OS", which is named after "bitcoin", which is also a tribute to the inventor "Satoshi Nakamoto". At present, from the technical details given by the bitcoin OS team, we may be able to see some aspects of this "blockchain 3.0" project
firstly, the management function of the account book system supports locating the ownership of resources according to the account ID, such as the private key; Computing resource management can obtain corresponding computing resources according to the demand, support edge computing, and share distributed computing power. In addition, storage resource management can use storage resources according to the demand, and support edge storage. Compared with bitcoin OS, Ethereum only supports account system and smart contract, which can not meet the distribution of distributed computing tasks. Ethereum only supports the fair execution of contract code, let alone the management of storage resources. So Ethereum is only a custom calculator
in addition, it is worth mentioning that bitcoin OS self customized enhanced smart contract. It supports two modes, which are more flexible and efficient
1. Central computing mode: the outgoing node is responsible for executing the smart contract, and both the incoming parameters and the output results support sipfs to be stored in the storage node
Distributed computing mode: ordinary nodes can claim computing tasks, input parameters and output results support sipfs storage to storage nodesfinally, we also need to mention the built-in sipfs super interstellar file system of bitcoin OS. Sipfs can realize the decentralized storage of technical input parameters and output parameters. At the same time, the file has a life cycle, and the DNA description of the file descriptor is recorded on the blockchain. The file descriptor of sipfs does not exist on the blockchain, but it will be stored in a separate file descriptor data file. After the end of the file life cycle, the blockchain will automatically delete the file descriptor, Realize the intelligent slimming of blockchain
"blockchain 3.0" is worth looking forward to, and bitcoin OS team, as the vanguard, is worth paying attention to and encouraging. We are looking forward to the real blockchain operating system
Because the blockchain technology is not mature at this stage, and the infrastructure is not perfect, many applications are limited, and the overall application is still in a very early stage
First of all, the main function of blockchain is to store information. Any information that needs to be saved can be written to or read from the blockchain, so it is a database. Secondly, anyone can set up a server and join the blockchain network to become a node. In the world of blockchain, there is no central node (decentralization). Every node is equal and keeps the whole database. You can write / read data to any node, because all nodes will be synchronized in the end to ensure the consistency of the blockchainChinese Name: Thomas Alva Edison
English Name: Thomas Alva Edison
a world-famous American electrician and inventor, known as the "king of invention in the world", has made more than 1000 inventions in his life. In addition to his invention and contribution in phonograph, electric lamp, telephone, telegraph, film and other fields, he also has many famous creations and insights in mining, construction, chemical instry and other fields. Edison had about 2000 inventions in his life, which made great contributions to the civilization and progress of mankind
Edison was also a great entrepreneur. In 1879, Edison founded "Edison Electric lighting company". In 1880, incandescent lamps went on sale. In 1890, Edison had established its various businesses into Edison General Electric Company. In 1891, Edison's thin filament and high purity blank incandescent bulb were patented. In 1892, Tom was born; Houston incorporated with Edison power lighting to form general electric company. General Electric began to dominate the electric field for a century< Edison was born on February 11, 1847 in Milan, Ohio, a small town in the Midwest of the United States. His father is a descendant of the Dutch, and his mother, a former primary school teacher, is a descendant of the Scots. When Edison was 7 years old, his father lost money in the tile business and moved his family to Fort gratiott, a northern suburb of Huron, Michigan. Soon after he moved here, Edison suffered from scarlet fever, which is believed to be the cause of his deafness. Edison went to school at the age of 8, but after only three months of reading, he was expelled from school by his teacher as an "imbecile". From then on, his mother was his "tutor.". Because of his mother's good ecation method, he became interested in reading“ He not only read extensively, but also read everything at a glance. At the age of 8, he read the works of Shakespeare and Dickens, the most important playwrights in the British Renaissance, and many important historical books. At the age of 9, he could quickly read difficult books, such as nature and experimental philosophy by Parker. When I was 10 years old, I loved chemistry. At the age of 11, he experimented with his first telegram. In order to make money to buy chemicals and equipment, he began to work. At the age of 12, he got a job selling newspapers on the train, traveling between Port Huron and Detroit, Michigan. He sells newspapers while doing fruit and vegetable business. Whenever he has time, he goes to the library to read. He bought an old printing press and began to publish his weekly, the herald, the first of which was printed on the train. With the money he earned, he set up a chemical laboratory on the luggage cart. Unfortunately, once a chemical caught fire and he and his equipment were thrown out of the car. Another time, while Edison was trying to get on a freight train, a conctor grabbed his ears to help him get on. This action led Edison to be deaf for life< In August 1862, Edison rescued a boy who was about to die on the train track with great courage. The father was grateful for this, but he was willing to teach him telegraph technology because he had no money to pay for it. From then on, Edison had a relationship with this mysterious new world of electricity and embarked on the journey of science< In 1863, Edison served as the telegrapher of Stratford junction station on the main line railway. From 1864 to 1867, he worked as a telegraph operator in the central and western regions and lived a life similar to wandering. Footprints, including Stratford, Adrian, Fort Wayne, Indianapolis, Cincinnati, Nashville, Tennessee, Memphis, Louisville, Huron and other places< In 1868, Edison came to Boston as a telegraph operator. In the same year, he obtained the first patent for invention. This is an automatic voting device. Edison thought the device would speed up the work of Congress, and it would be popular. However, one congressman told him that they had no intention of speeding up the agenda and that sometimes voting slowly was out of political need. From then on, Edison decided not to invent anything that people didn't need< In early June 1869, he came to New York to look for a job. While he was waiting for a call in an agent's office, a telegraph broke down. Edison was the only one there who could fix the telegraph, so he got a better job than he expected. In October, he and Popper set up a "Popper Edison Company" to specialize in scientific instruments for electrical engineering. Here, he invented the "Edison universal press". He dedicated the press to the manager of a big Wall Street company. He wanted to ask for $5000, but he didn't have the courage to say it. So he asked the manager to give him a price, and the manager gave him $40000<
Edison used the money to build a factory on ward street in Newark, New Jersey, which specializes in manufacturing all kinds of electrical machinery. He works all night. He trained a lot of capable assistants. At the same time, he also ran into the diligent Mary, his first bride in the future. In Newark, he made such inventions as wax paper and mimeograph. From 1872 to 1875, Edison invented the double Telegraph and quadruple telegraph, and helped others build the world's first English typewriter< In the spring of 1876, Edison moved to "Monroe Park" in New Jersey. He built the first "invention factory" here, which "marks the beginning of collective research". In 1877, Edison improved the telephone invented by Bell and put it into practical use. He also invented his favorite project, the phonograph. Telephone and Telegraph "is a revolution to expand human sensory function"; Gramophone is one of the three great inventions that changed people's lives. "From the perspective of invention imagination, this is his extremely important invention achievement.". By this time, people called him "the magician of Monroe Park"< When Edison invented the phonograph, he finally made a breakthrough in the research of electric lamp after numerous failures. On October 22, 1879, Edison lit the first electric lamp with wide practical value. In order to extend the life of the filament, he retested, and tried out more than 6000 kinds of fiber materials before finding a new luminous body, Japanese bamboo silk, which lasted for more than 1000 hours, and achieved a rable purpose. In a way, this invention is the highest achievement of Edison's life. Then he created a power supply system that allowed distant lamps to be distributed from a central power station, a major technological achievement
his first discovery in pure science appeared in 1883. When experimenting with electric lamps, he observed what he called the Edison effect: an electric charge in the lighted bulb passes through space from the hot filament to the cold plate. Edison patented the discovery in 1884, but did not study it further. Other scientists used the Edison effect to develop the electronic instry, especially radio and television
Edison tried to do what the phonograph did for the ear for the eye, and the film camera was born here. Using a new Celluloid film invented by George Eastman, he took a series of photos and projected them onto the screen quickly and continuously, creating the illusion of movement. He first experimented with films in the laboratory in 1889 and patented them in 1891. In 1903, his company proced the first feature film "train robbery". Edison did a lot of work for the formation and standardization of the film instry< After Edison moved his laboratory to West Orange in 1887, he founded many commercial companies to make procts and promote sales for his various inventions; These companies later merged into Edison General Electric Company, later known as general electric company. Since then, his interest has shifted to fluorimetry, ore crushers, magnetic separation of iron, batteries and railway signaling devices
ring World War I, he developed torpedo mechanisms, flamethrowers and underwater periscopes< On October 21, 1929, on the 50th anniversary of the invention of electric light, people held a grand celebration for Edison. Famous scientists such as Einstein of Germany and Madame Curie of France congratulated him one after another. Unfortunately, at this celebration, when Edison delivered his reply, he suddenly fainted e to excessive excitement. From then on, his health went from bad to worse. On October 18, 1931, the scientist who had made great contributions to mankind died of illness at the age of 84
Edison's ecation level is very low, but his contribution to mankind is so great. What's the "secret" here? In addition to a curious heart, he has an instinct to test himself, that is, he has the infinite energy and bold spirit of extraordinary hard work. When someone called Edison a "genius", he explained: "genius is one percent inspiration and ninety-nine percent perspiration." In the "invention factory", he organized many people of different professions, including more than 100 scientists, engineers, technicians and workers. Many of Edison's major inventions were successful thanks to this collective force. His achievements are mainly e to his hard work and creative ability as well as the collective strength. In addition, his wife also played a very important role< In August 1862, Edison rescued a boy who was about to die on the track of a train. The father was grateful for this, but he was willing to teach him telegraph technology because he had no money to pay for it. From then on, Edison had a relationship with this mysterious new world of electricity and embarked on the journey of science< In 1863, Edison worked as a telegrapher at Stratford junction station of the main line railway. From 1864 to 1867, he worked as a telegraph operator in the central and western regions and lived a life similar to wandering.

In October, he and Popper set up a "Popper Edison Company" to specialize in scientific instruments for electrical engineering. Here, he invented the Edison general seal
Let me answer the questions one by one
1) is blockchain legal
blockchain is a kind of technology. To ask whether blockchain is legal, we can take the example of fast broadcast
blockchain is a P2P network based on the Internet, which was first used in bitcoin protocol in October 2008. Bitcoin is a virtual currency system; It decentralizes currency issuance, ownership transfer and transaction confirmation. Bitcoin is the first application case of blockchain technology. Digital currencies such as Puyin, Laite coin and doggy coin are also the application of blockchain.
