Blockchain industry ecosystem
IBM and giant automobile manufacturers are trying to use blockchain technology to solve instry pain points. In addition, there are "declining" enterprises such as Kodak of Japan, hoping to fight a "turnaround battle" through blockchain
What does these phenomena show? This shows that the technology of block chain has great commercial value. Everyone hopes to cultivate a new world on this unknown land. So, with the development of blockchain technology this year, it has not only been a simple underlying technology, but also formed a complete ecosystem. Now let's talk with you from two aspects of "coin circle" and "chain circle": what is the ecosystem of blockchain, and let's understand the whole picture of blockchain instry
the first section of the coin circle
in the coin circle, there are always several terms: project party, exchange, media, mining machinery manufacturer. Next, let's take a detailed inventory of what's going on
first, the project side of the coin circle can be understood as follows: all those who issue tokens are the project side. Attention, it's a coin ring. There are also some project parties that don't issue money, such as Alibaba, Tencent and Netease, which are also doing blockchain projects. They don't issue money and only focus on technology. Then these project parties that don't issue money mainly focus on the role of blockchain in data security and supply chain, which we will talk about later
let's return to the topic of coin circle project parties. For example, yilaiyun and BoChang, which are more controversial recently, are the project parties of coin circle, as well as blockchain games, which are more popular recently. They also belong to coin circle project parties
one of the subversive aspects of the coin circle project is the combination of the project and the token, which directly replaces the equity with the token, and the token can be directly circulated. This is a very revolutionary point, so that many initial projects can be more convenient for financing. After financing, the feedback token can be circulated on the digital currency trading platform, and the investors can also exit very well
this "financing investment" approach seems to be another way to realize the listing and trading of equity in disguised form
therefore, it is such a mode that makes the project side of the coin circle the nearest place to the money. They can easily circle the money, and of course they can't resist the temptation, or they have been planning for a long time and run away after circling the money. The detailed process of token issuing by the project side is generally as follows:
the first step is to build a token system, which is similar to an app application. This is not very complicated, because Ethereum is open source, similar to Android Apple system, on which developers can develop specific applications
the second step is to write a white paper, which is similar to the business plan. The white paper is similar to the business plan, mainly including the team situation, technical situation and other information of the project
the third step is to find someone to do endorsement, and find some influential instry bigwigs to promote
the fourth step is to promote marketing, find some blockchain media to push soft articles and pull cooperation, which we will mention below
the fifth step is to find financing
Step 6: go to the stock exchange, and the token begins to spread widely
Second, the exchange
with the project side, let's talk about the exchange. If the project side is a procer, then the things they proce have to be sold and traded, right? The exchange is a trading place for the token of the project party. If the token of the project side is similar to the stock, then the exchange of the currency circle is similar to the secondary market of the stock market. However, the exchange of the currency circle has more power. It has the right to audit the currency, and can decide whether to put the currency in or out
of course, if the project party wants to pay the exchange a huge amount of money charging fees, the investors who trade in the exchange also need to pay the handling fee or withdrawal fee, and the rules of the handling fee and withdrawal fee of each exchange are different. In fact, the currency fees, handling fees and cash withdrawal fees constitute the profit model of the currency circle exchange. Of course, in addition to these three profit models, the profit model of the exchange includes the "market maker" business to earn the price difference, that is, the exchange creates liquidity through continuous trading, acts as a market maker and earns the price difference at the same time
at present, e to the increasingly fierce competition in the instry, there will be less and less currency fees and handling charges, or even no need, so the proportion of conventional profits will be less and less, which leads to the emergence of other profit models, such as platform currency and leverage handling charges. Let's talk about platform currency first. Platform currency is the currency issued by the exchange: okb and coin an belong to platform currency. These platform currencies issued by the exchange can be exchanged for BTC and eth. At the same time, the appreciation of platform currency's own value can lay a solid material foundation for the development of the exchange. For users, holding platform currency can enjoy the benefits of commission discount, platform dividend, special activities of the exchange, etc, This is platform currency. Leverage service charge refers to the currency financing function on the platform, which supports leveraged transactions and charges a certain proportion of service charge to currency financing users
all of the above are actually ecosystems constructed through the exchange's own resource output. Now, the exchange is still actively planning the whole instry to obtain income, such as the establishment of capital, mine pool, wallet, incubator, Engineering Institute, fund and other ways. We believe that if the exchange wants to develop for a long time, it must lay out the whole instry chain, find new breakout points of the instry, and build a complete ecosystem. Therefore, the proportion of strategic profits should be increased
3. Blockchain media
in the past two years when blockchain is hot, there are not only a lot of project parties, but also media. At present, there are about 200 well-known blockchain media. The content on the blockchain media platform is about the following points: policy, hacker, exchange, boss and project party. In addition to words, the operation mode of blockchain media also includes community activities, such as inviting "big guys" to share in the group, so as to achieve a precipitation of high-quality content and earn some traffic at the same time
Why do we have to mention blockchain media? It's because there are some differences between blockchain media and the media in our impression. What's the difference? The difference is that there are some interest relationships between blockchain media and the above mentioned project parties and exchanges. We just said that the project side is like a "procer" and the exchange is like a "sales market". Then, the role of the media is like "advertising platform & quot;. If the project wants to sell well, it needs publicity and advertising, then blockchain media plays such a role. Therefore, the investors of some blockchain media are the project side and the exchange
recently, there has been a bear market. Many blockchain media have laid off employees on a large scale. The reason is nothing more than the shortage of projects and funds. Therefore, it is far from enough for blockchain media to rely solely on the investment of the project side, the exchange and the advertising revenue. When the bear market comes and the project side and the exchange are affected, then the media is bound to face a very cruel winter. As a result, many blockchain media are also doing token issuing by project parties (the most typical are content communities such as coin and coin car, which belong to a media platform and are also doing token issuing by project parties), or some blockchain media are doing business such as wallet selling, mining machine renting and computing power
however, we believe that blockchain media, as the media, still play the role of guiding public opinion. Therefore, we should return to the essence and be a place to deliver instry value information, rather than a place to pile up advertisements. Therefore, blockchain media should keep up with the development of technology to realize its own survival and development. Relying on the advantages of blockchain technology and based on the consensus mechanism in the token system, it can realize the reasonable distribution of the interests of the media instry. In this regard, it may have a certain imagination< Fourth, mining machine manufacturers
in the final analysis, bitcoin mining is the competition of computing power. The stronger the computing power, the greater the probability of bitcoin mining. Therefore, in the business system of the whole coin circle, mining machinery manufacturers are a very important existence. We can see from one data: in the blockchain instry of Hurun 100 rich list in 2018, the richest person is Mr. Zhan ketuan, a partner of bitcontinental, a miner. In addition, according to the prospectus, bitcoin's net profit in the first half of the year was US $743 million, an increase of nearly eight times over the same period last year. Bitcoin once occupied more than 70% of the global market share of mining machinery, becoming the leader in the mining machinery instry. Not only mining machinery, bitmainland still occupies a near monopoly position in the mining pool (that is, a mode of cooperative mining): at present, the computing power of the top six mining pools in the world accounts for 79.2%
after the invention of China's first bitcoin miner, Jianan Yun, another miner chip research company, began to engage in the research of chips in the field of blockchain and artificial intelligence. In just a few years, it has also become an internationally famous chip enterprise
in fact, as early as 2012, the United States announced that it was going to sell a butterfly miner, but many people later thought it was a scam, because it took several years for the butterfly miner to go on sale, which also made the R & D of mining machines in other countries become very scared, and they were all scrambling for time, in a sense, Butterfly mining machine is also driving the prosperity of mining machine instry. So, in 2013, the mining machine has entered a season of contention, and a large number of ASIC mining machines have been put forward: or announced research and development, or announced pre-sale, or in the form of spot: cat roasting mining machine, pigeon mining machine, TMR mining machine, biter mining machine, Rand mining Bureau, little bee mining machine, Avalon original factory and various OEM, garden mining machine, Smart mining machine and so on... Maybe you haven't heard of these mining machines, because they are basically dead. Bitcontinental, Jianan Yun and Yibang have become mining machine giants< However, as a derivative instry under the prosperity of cryptocurrency market, the price of mining machinery is closely related to the cryptocurrency Market: in the bull market, the supply of mining machinery often falls short of demand, and it is common for miners to buy Mining machinery from "scalpers" at several times high prices. At this time, mining machinery manufacturers enter the dividend period. However, in a bear market, mining machinery manufacturers will also be adversely affected. As miners' enthusiasm for mining declines, some manufacturers have to rece the price of mining machinery to recover costs. For example, when bitcoin plummeted in March this year, a certain model of mining machine sold by Huaqiangbei was on sale at a price of 5000 yuan, and the price dropped from about 19000 yuan to
14000 yuan
[summary]
at this point, we can find that whether it is the project party, the exchange, the media, or the mining machinery, it can be said that it is a kind of "one-stop"
, under the testimony of the leaders of Hunan high tech Zone, will jointly publish the first 2018 global chain chain instry yearbook by China Mobile communications Federation, international block chain application alliance, self chain college and Wutong think tank. The details are as follows:
since October 2016, the Ministry of instry and information technology has issued the white paper on China's block chain technology and application development (2016). Blockchain was identified as a strategic frontier technology for the first time and was written into the notice of the State Council on printing and distributing the 13th five year plan of national informatization issued by the State Council in December 2016. The plan clearly puts forward the need to strengthen the innovation, test and application of new technologies such as blockchain, so as to seize the leading power of the new generation of information technology
local governments have also issued guidance and notification documents on blockchain. According to financial statistics, as of March 2018, Beijing, Shanghai, Guangzhou, Shenzhen, Zhejiang, Jiangsu, Guizhou, Fujian, Guangdong, Shandong, Jiangxi, Inner Mongolia, Chongqing and other provinces and cities have issued guidance on blockchain
Chen Xiaohua, director of ecation and examination center of China Mobile Communications Federation, Secretary General of international blockchain innovation and application alliance of China Mobile Communications Federation, and President of Beiyou online digital economy research institute, said: "one of the biggest values of blockchain technology is the combination with big data. Blockchain technology will be the key technology to build a social big data platform. The combination of blockchain and big data will solve the deep-seated problems of data interconnection and open sharing. "2018 global blockchain Instry Yearbook" is a big database of blockchain ecological information. Through research and aggregation of the whole ecological instry data of blockchain, it provides authoritative system data mining analysis, data docking and matching, intelligent information flow and instry spectrum for blockchain enthusiasts, avoids learning blind spots, popularizes blockchain knowledge, and promotes the healthy development of blockchain ecology. "
"the development of blockchain in the past two years is obvious to all. Local governments are also more active in promoting the development of blockchain technology and application. With the innovation and upgrading of blockchain, deep integration and innovation with cloud computing, big data and other cutting-edge technologies, it will promote the application of blockchain technology in medical, judicial, instrial, media and other fields Business exploration and application of games and other subdivided fields. The healthy development and application of blockchain in the future cannot be separated from the construction and improvement of instry ecology. From 2015 to 2018, more than 50 instry associations / alliances related to blockchain have been established in China, and blockchain media and institutions emerge in an endless stream. With the rapid development of blockchain, a large number of enthusiasts, practitioners, entrepreneurs and investors will participate in the future, And the 2018 global blockchain Instry Yearbook provides an authoritative platform for them to systematically understand the blockchain instry. " Tang Yuze, President of the Institute of creative talents of Wutong think tank, believes that the 2018 global block chain instry yearbook will have a significant impact on the future development of the block chain.
as one of the sponsors of this yearbook, Jian Jinqiu, founder of Zilian college, said: "technological innovation is the core driving force for the in-depth development of the blockchain instry, and the technological innovation of China's blockchain instry is undergoing a process of obvious acceleration. Thanks to the continuous innovation of blockchain technology and China's huge Internet consumer groups, blockchain applications in China also show a wide range of diversified and active characteristics. From 2016 to 2018, private equity investment in China's blockchain field has been invested in many fields, such as blockchain personnel training, infrastructure, underlying technology, related services, blockchain application, etc., and China's blockchain instry chain has basically taken shape. And the government is increasingly facing up to and affirming the value of the blockchain, and the launch of the 2018 global blockchain Instry Yearbook is to build a good blockchain instry ecology and promote the healthy development of the blockchain instry. "
with the continuous excavation of the potential value of the blockchain, the heavyweight multinational instry giants have entered the blockchain field by setting up research groups, investing in blockchain start-ups, developing the basic platform of blockchain, and studying the potential application scenarios in the future. Their demonstration and leading role has begun to drive a new round of blockchain entrepreneurship and innovation wave. As the world's first blockchain Yearbook, 2018 global blockchain Instry Yearbook will invite world-renowned scholars and enterprise experts to write it, and give full play to the role of blockchain policy guidance to better promote the healthy development of the blockchain instry
Original title: China's blockchain instry market status and development trend analysis in 2019, widely used to accelerate the construction of Digital China. Basically, a relatively mature instrial chain has been formed. With the promotion of national policies and the increasing demand of downstream application fields, the market scale of China's blockchain instry is constantly developing, the regional concentration is high, and the instrial cluster effect is obvious. With the increasing maturity of blockchain technology, the blockchain instry is entering the 3.0 stage as a whole. It has a good performance in finance, logistics, right protection and other fields, and has made great contributions to promoting China's digital construction and accelerating the process of Digital China
instrial chain analysis of blockchain instry: there are many downstream application fields with huge development potential
from the perspective of instrial chain, China's blockchain instry includes upstream hardware, technology and infrastructure; Midstream blockchain application and technical services
application fields of downstream blockchain. The upstream hardware, technology and infrastructure mainly provide the necessary hardware, technology and infrastructure support for blockchain application. The hardware equipment includes mining machinery, ore pool, chip manufacturer, etc; General technologies include distributed storage, decentralized transaction, data service, distributed computing and other related technologies
the downstream application fields include the combination of application blockchain technology and existing instries, mainly including financial instry, logistics instry, right protection, medical health, instrial energy and many other fields. As an emerging technology, blockchain has many downstream application fields and great development potential
the application and service of midstream blockchain includes the construction of infrastructure platform and the provision of technical service support. The construction of infrastructure platform is divided into general infrastructure chain and vertical domain infrastructure chain; Technical service support includes technical support and service support. Similar to upstream technology, technical support is responsible for providing buyers with a series of technical support based on blockchain procts, such as blockchain security protection; Service support includes a series of services such as digital asset trading place, digital asset storage, media community, etc
instry chain analysis of blockchain instry Most of 360 and other enterprises use their own financial companies to apply blockchain technology to launch a new mode of blockchain + finance and broaden the application scenarios of blockchain technology
With the continuous development of China's blockchain technology and the continuous expansion of blockchain application fields, China's blockchain instry will become the forefront of global technology development and open up a new international competition track in the future2. Blockchain has become a new hot spot for innovation and entrepreneurship, and technology integration will expand new application space
3. Blockchain will be widely implemented in the real economy in the next three years and become an important support for the construction of Digital China
4. Blockchain creates a new platform economy and opens a new era of sharing economy
5. Blockchain accelerates the process of "credible digitization" and drives finance to "move from virtual to real" to serve the real economy
The blockchain supervision and standard system will be further improved, and the instrial development foundation will continue to be consolidatedthe alliance is jointly sponsored by 24 enterprises, institutions, universities, instry media and associations, including Shenzhen Branch of China Quality Certification Center, Tencent, Cisco, CIMC, Zhongan technology, Neusoft group, Shenzhen IOT Media Co., Ltd., Shenzhen Institute of standards and technology, Shenzhen University blockchain technology research center, and is committed to focusing on promoting blockchain technology research Achievements transformation, application promotion and instrial development
recently, blockchain technology has been highly affirmed by the Political Bureau of the CPC Central Committee. The stock prices of listed companies involved in the concept of blockchain have skyrocketed, and the market is hot. It is also hotly discussed that blockchain has been "turned into a regular" by the state, so the future prospects are bound to be bright
now, the year is coming to an end, and 2019 will come to an end. One year later, what progress has Shenzhen blockchain instry alliance made
let's take a look at the progress of the following four instry alliance members first< At the original founding meeting, Tencent was selected as the chairman of Shenzhen blockchain instry alliance, and Cai Yige, general manager of Tencent blockchain business, served as the chairman of the alliance
now, Cai Yige will be the general manager of Tencent virtual bank blockchain
it is reported that at the recent "2019 world blockchain conference · Wuzhen", Cai Yige disclosed that Tencent has obtained the virtual banking license granted by the Hong Kong Monetary Authority and is preparing the virtual banking blockchain project. At present, Tencent has digital asset practice in supply chain finance and improving asset and capital allocation efficiency
from the general manager of blockchain business to the general manager of virtual bank blockchain, the stage will naturally be broader< In 2019, as the representative of blockchain enterprises, Cisco participated in the preparation of national standards for blockchain
on April 3, 2019, China Institute of Electronic Technology Standardization (hereinafter referred to as the Institute) organized experts to successfully hold the first working group meeting of the national standard 2019 of "information technology blockchain and distributed ledger technology reference architecture" in Shanghai

in the future, we will continue to speed up the promotion and implementation of blockchain plus Internet of things system solutions, and improve and optimize the terminal equipment and software platform for anti-counterfeiting, traceability, warehouse inventory, smart retail, data acquisition and other systems
so far, 69 patents related to "Internet of things + blockchain" have been submitted, 47 invention patents, and the rest are utility models and layout designs
as the technical supporter of Walton chain, Cisco tries to go further on the road of combining hardware with software
the company's key proct is the combination of self-developed RFID chip and Walton chain (commercial bottom public chain), which uses the technology features of blockchain chain, such as non tampering and full process traceability, to serve the scene data collection and traceability applications in food, clothing, retail, power grid equipment, art and other instries, Form a standardized comprehensive solution for data collection, certification and traceability of various instries< Zhongan Information Technology Services Co., Ltd.
as the first Internet insurance company that hopes to reshape the insurance value chain through science and technology, Zhongan has set up a blockchain team since 2015 to reserve core technology and explore the deep integration of blockchain technology and instrial innovation. Up to now, it has submitted 129 blockchain related patents, 112 of which can be checked publicly
"in the future, Zhongan blockchain will focus more on the exploration of insurance. Sooner or later, blockchain and smart contract will have a significant impact on insurance. We have started to penetrate from simple and marginal business. From the early health insurance policy deposit, to the claim efficiency of smart contract, and then to the policy token, we hope to use technological innovation to release manpower, improve efficiency, rece transaction friction and loss between collaborations, and create a real new insurance. " Zhongan technology CTO Li Xuefeng said recently
in 2019, Zhongan science and technology will focus on supply chain finance. In view of the long-standing bottlenecks of supply chain finance, such as fraud risk, information island, difficult credit transmission and high performance risk, Zhongan science and technology will launch the "Zhongan chain" to build a safe and reliable supply chain financial ecosystem with enterprises in the "double chain" mode of block chain and supply chain
at present, the safety chain of many enterprises has been graally implemented in the supply chain scenarios of automobile manufacturing, logistics, construction, e-commerce and medical drugs, covering the online receivables transfer, financing, management and settlement needs of core enterprises and their upstream suppliers< As one of the largest IT solutions and service providers in China, Neusoft Group Co., Ltd., the vice chairman unit, is increasing investment, strengthening strategic deployment in the field of blockchain technology and expanding its business
by using aiguille BCP peak series blockchain technology application platform, the blockchain and the current mode of enterprises are integrated and innovated
it is reported that as a new computer application technology and basic technology, Neusoft group has started tracking and pre judging since the beginning of 2016, strengthened ecological cooperation, combined with the company's main business to achieve more scenario applications, provided more solutions for users, and realized the real implementation of blockchain technology
in the application of blockchain technology, Neusoft group mainly uses application scenarios to drive the selection of technical routes and the establishment of cooperation ecology. In February 2018, Neusoft group developed a blockchain based medical data sharing platform (carevault)
in 2019, Neusoft has developed a licensed drug and equipment traceability management platform for Hainan Bo'ao Lecheng International Medical Tourism pioneer zone

It has the functions of online electronic approval, traceability supervision and adverse reaction monitoring of licensed drugs and medical devices, To provide information support and reasonable and effective supervision means for the whole process traceability supervision business of licensed drugs and equipment
summary:
there is a long way to go for the development of blockchain technology landing scenarios. How to enable the instry to become a standardized technical infrastructure needs long-term exploration and running in.
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
future development and application scenarios of blockchain
1. Digital identity
many people will encounter the dilemma of "proving that my grandmother is an alt" and "my mother is my mother" when they open various certificates. With blockchain, they will never have to worry about it again. It turns out that our birth certificate, real estate certificate, marriage certificate and so on need a central node for everyone to recognize. Once transnational, contracts and certificates may become invalid because of the lack of a global central node
the tamper proof feature of blockchain technology has fundamentally changed this situation. Our birth certificate, real estate certificate and marriage certificate can be notarized on the blockchain and become something trusted by the whole world. Of course, it can also easily prove that "my grandmother is an alt" and "my mother is my mother"
2. Health care
in short, it is to use blockchain to establish a general record repository with time stamp, so as to achieve the purpose of extracting data information from different databases
3. Travel consumption
when we travel, we often use Ctrip, meituan and other apps to find and place orders for hotels and other services, and each platform gets a commission from them. The application of blockchain is to remove middlemen and create a secure and decentralized way for service providers and customers, so as to achieve the purpose of direct connection and transaction
4. More convenient transaction
blockchain can make payment and transaction more efficient and convenient. The blockchain platform allows users to create smart contracts that become active when certain conditions are met, which means that automatic payment can be released when both parties agree to meet their conditions
5. Strictly control the proct quality
if you buy an apple, under the blockchain technology, you can know the whole process from the proction of fruit farmers to the circulation. Among them, there are government regulatory information, professional testing data, quality inspection data of enterprises and so on. The smart supply chain will make the food we eat and the goods we use safer and more reassuring
6. Art of property rights protection
the creator puts his works on the blockchain. Once someone uses his works, he will know immediately. The corresponding royalty will also be automatically paid to the creator. Blockchain technology not only protects right, but also helps creators sell their works to consumers more directly without the assistance of distribution companies.
The application prospects of blockchain are mainly in the fields of finance, Internet of things and logistics, public services, digital rights and insurance
1. Blockchain has great potential applications in international exchange, letter of credit, equity registration, stock exchange and other financial fields. The application of blockchain technology in the financial instry can eliminate the third-party intermediary link and realize the point-to-point direct docking
2. Blockchain can also be naturally combined in the field of Internet of things and logistics, which is considered as a promising application direction of blockchain. The establishment of credit resources in the blockchain can double improve the security of transactions and improve the convenience of Internet of things transactions. It can save time and cost for the application of intelligent logistics mode
3. Blockchain is closely related to people's proction and life in public management, energy, transportation and other fields. The decentralized and fully distributed DNS service provided by blockchain can realize the query and resolution of domain name through the point-to-point data transmission service between nodes in the network
4. Through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership. After the works are confirmed on the blockchain, the subsequent transactions will be recorded in real time to realize the full life cycle management of digital rights, and can also be used as a technical guarantee in judicial evidence collection
5. In terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized
extended data:
the core technology of blockchain
1. Consensus mechanism, through the voting of special nodes, completes the verification and confirmation of transactions in a very short time; For a transaction, if several nodes with unrelated interests can reach a consensus, it can be considered that the whole network can also reach a consensus. The goal of blockchain consensus mechanism is to make all honest nodes keep consistent blockchain views
2. Asymmetric encryption requires two keys for encryption and decryption, which are public key and private key. The public key corresponds to the private key. The public key is used in the process of data encryption, and only the corresponding private key can be used to decrypt; On the contrary, the private key is used to encrypt the data, and only the corresponding public key can be used to decrypt the data
1. Decentralization
the core advantage of blockchain technology is that it does not need a traditional centralized organization, and does not rely on the point-to-point transaction, coordination and cooperation of a credit center in the distributed system, so as to avoid the common problems of data security, collaborative efficiency and risk control of centralized organizations
2. High security
in blockchain technology, data is difficult to tamper with. Anyone can access the database that records transactions. In this transparent and open mode, everyone can act as a supervisor. We can see at a glance what changes have taken place in the data, which is more secure than traditional technology
3. More reliable
the blockchain technology is connected by multiple nodes in different places. The nodes in the blockchain interact through the point-to-point communication protocol. Under the condition of ensuring the consistency of the communication protocol, different nodes can be processed by different developers using different programming languages and different versions of the whole node
in short, when a node encounters network problems, hardware failures, software errors or is controlled by hackers, the operation of other participating nodes and systems will not be affected
therefore, blockchain is more reliable than traditional technology
therefore, I firmly believe that the application of blockchain must be the development trend in the future.
Blockchain Instry Yearbook is a comprehensive and informative large-scale tool book that comprehensively reflects the development of global blockchain instry, and has been published continuously year by year The blockchain Instry Yearbook is based on the continuous observation and research of the global blockchain instry, as well as enterprise interviews, media docking, and employee research, which makes a detailed division of the current mainstream blockchain instry ecosystem.
