How to develop projects with blockchain
first, how to make a fixed investment
1, why should we make a fixed investment? Because no one can determine where the bottom is, blockchain is high-risk and high-yield, and only through fixed investment can the risk be reced
2. What kind of assets are worth fixed investment
one is hard currency bitcoin, the other is widely used ether currency, and the third is a new currency with good credit endorsement. Team background must be strong
3. When is the fixed time
you can make a fixed investment every week, every two weeks and every month. If you even have trouble making a fixed investment every month, I suggest you stop making money and go to sleep
4, how much capital will be invested
the suggestion of blockchain Dashen laomao is that within the range of 10% ~ 30% of your disposable assets, I will calculate it by 20%. For example, if you have a disposable asset of 100000 yuan, you can arrange 3000 yuan for investment from your income every month. If your fixed investment period is two years, then your total investable capital is 100000 * 20% + 3000 * 24 = 92000 yuan. Divided by 24 months, you can invest 3833 yuan per month and 958 yuan per week< Second, diversify investment
after listening to the sharing of laomao and other gods, the suggestions for blockchain assets are as follows: 50% bitcoin + 15% eth + 15% your favorite small currency + 20% crowdfunding new currency.
the mainstream currency is low-risk and low-income. Small currency is a hobby, and the potential of new currency is huge. Its income will one day become your main asset, such as 1 yuan crowdfunding ant stocks, up to 1400 + yuan. Strong background of the team + pragmatic landing, as long as given the time, in this circle to return a hundred times a thousand times is very normal! Among them, blockchain + finance is the easiest scene to implement, so the projects of asset chain have always been popular
we recommend a popular project, sealchain financial public chain, which directly covers seven financial application scenarios, including Inclusive Finance, supply chain finance, ABS, insurance, equity, corporate bonds and intelligent investment advisory. It is expected to become a black horse in the money circle from 2019 to 2021! And in 2019, the exchange price is only 1 yuan!
with the global hot discussion of the concept of "blockchain", the application of blockchain technology has been quietly added to the daily life scenes such as finance, logistics, credit reference, manufacturing and retail. Some experts have shown that the future blockchain will be closely related to people's lives, and the integration of blockchain technology and people's daily life is the general trend
the popularity of the blockchain market has triggered a large number of talents demand based on blockchain technical personnel, and the popularity of blockchain talents is rising at the speed of light. According to the "2018 blockchain high salary list" released by lagou.com, Tencent, Xiaomi, Suning, Jingdong and other domestic enterprise giants have released many high salary blockchain post demands, trying to explore blockchain related technologies and applications. It is also pointed out in the list that the demand for high salary jobs is mainly based on blockchain related technical jobs, among which Suning and Keda have been given the highest monthly salary of 100k
the huge market demand for technical talents will inevitably lead to the explosive emergence and growth of the whole blockchain training market. Most of the training modes can be divided into online training, traditional IT organization training, and offline short-term training camps, which mainly focus on high-end forms. However, in the process of the hot market evolution, there are also a variety of blockchain training chaos: lecturers' qualifications are watered down, and even the most basic names are not disclosed, the syllabus is opaque, and the teaching quality is shrinking, Unreasonable class arrangement and uneven training fees and so on
with the large-scale development of the whole blockchain training market, brother company ecation, together with Yin Cheng, a senior blockchain expert, and his Tsinghua Shuimu Weiming team, has set up a blockchain college. With its professional and powerful team of technical lecturers, detailed and comprehensive curriculum system, and a large number of authentic enterprise blockchain projects, it aims to deepen the blockchain teaching and training field, And train more professional technical talents for enterprises and society<
Yin Cheng, a senior blockchain technology expert, graated from Tsinghua University, is the dean of brother Lian blockchain college. He once served as Google Algorithm Engineer, the world's most valuable expert in the field of Microsoft blockchain, and the gold medal lecturer of Microsoft tech.ed conference. Proficient in C / C + +, python, go language, sicikit learn and tensorflow. With 15 years of programming experience and 5 years of teaching experience, senior software architect, Intel Software Technology expert, famous technology expert, with many years of working experience in the world's top it company Microsoft Google. He has many years of experience in software programming and lecturing, and has developed many procts in human-computer interaction, ecation, information security, advertising and blockchain system. He has deep experience in project management and R & D, has two AI invention patents, and has practical experience in developing e-money deployed to Microsoft Windows azure. Teaching explanation is in simple language, so that students can apply what they have learned
the first stage: blockchain instry and go programming for 5 weeks
the second stage: cryptography and consensus algorithm for 2 weeks
the third stage: Ethereum source code analysis and development for 3 weeks
the fourth stage: Super ledger and node.js for 2 weeks
the fifth stage: bitcoin & EOS for 4 weeks
the sixth stage: comprehensive actual combat of the project
some countries have shown great interest in the blockchain technology of decentralized data management framework to store public data. For example, essentia is developing an e-government project with the Central Union of agricultural procers and forest owners in Finland, The project will apply blockchain technology to enable urban and rural residents in Finland to query various records, fully meet the needs of residents and employers, and improve the employment rate. In addition, the use of this technology can also improve the efficiency of government operation, so that residents can easily query ecation, public records, voting and other information
waste recycling
for example, an intelligent waste management system in China adopts the RFID technology of waltonchain company. Using this blockchain application of waltonchain, it can effectively monitor the waste level, so as to improve the management and operation efficiency and resource optimization
identity recognition
chug, a Swiss city known as "encryption Valley", has developed an identity authentication system with its partner uport by using blockchain technology, through which citizens can participate in online voting and proof of residence
border control
essentia has been in contact with the Dutch government, hoping to use its blockchain technology to establish a set of border inspection system for the Dutch government to check passengers between Amsterdam and London. At present, passengers of Eurostar high-speed rail between the two countries need to undergo border control checks at multiple locations. Essentia is working on a blockchain based solution that will securely store passenger data so that inspection records from the Netherlands can also be reviewed by UK Border agencies. Blockchain technology will ensure that the data has not been tampered with and is verifiable and accurate
health care
as we all know, medical records are very scattered and prone to errors. Inconsistent data processing process will make hospitals and clinics often forced to deal with some incorrect or incomplete patient records. For example, Medrec, a blockchain electronic medical record system developed by MIT, uses blockchain technology to promote data sharing. At the same time, it can also provide authentication and confidentiality services
enterprise management
as enterprise customers of Microsoft azure applications, they can make use of blockchain as a service (baas), which will enable enterprises to access smart contracts and blockchain applications in a secure hosting environment. According to media reports, Google is also developing a proprietary blockchain project to support its cloud based business. And alpha, Google's parent company, is developing a distributed accounting project that third parties will be able to use to store data related to Google's cloud services
medical data
medical centers that digitize patient records do not store data among multiple devices. They usually store data on centralized servers, which has become the main target of hackers. The wannacry attack on NHS hospital in the UK proves this. But in addition, even if the security risk is ignored, there is still the problem of fragmentation. At present, there are more than 50 different electronic medical record systems (EHR) operating in hospitals in different cities around the world, and there are usually dozens of different medical application systems in the same city. These independent systems can't perform interoperation, and the data of patients in each hospital can only be distributed in different data storage centers
in the case of patients' life and death, the lack of reliable medical data contrast and slow operation efficiency will be fatal. Essentia's application framework solves all these problems by using blockchain based system, which will store all clinical data of patients, and can access these data immediately regardless of geographical boundaries. In this system, the patient's medical record privacy can also be protected, and only the authorized medical personnel can access it in a specific period of time
Music Proction
one of the main advantages of blockchain technology is that it eliminates unnecessary middlemen or middlemen. The music instry is a typical example. In this instry, if artists are inefficient, they will get very low remuneration. At this time, a number of blockchain based projects have emerged to seek a fairer trading and business environment for music creators, such as artbit, a former gunshot rose drummer Matt Soren as director
carbon compensation
as a highly instrialized country, China's environmental change is huge. In March 2017, IBM and energy blockchain labs jointly launched the hyperledger fabric blockchain project to discover China's carbon assets, which not only creates a measurable and auditable system for tracking carbon emissions, but also provides a tradable market for companies seeking to offset energy consumption and stimulate green instrial practice
supply chain management
supply chain management is considered to be one of the better cases of applying blockchain, because it is very suitable for the express delivery of such goods from delivery to receipt or the whole process from manufacturer to store. IBM and Wal Mart have jointly launched a blockchain food safety alliance in China. The project is also jointly operated with Jingdong company, aiming to improve food delivery tracking and safety assurance, so as to make it easier to trace food safety issues
facts have proved that China is a mature experimental base for blockchain projects, and it is also the location of the world's first blockchain for agricultural procts (5.180, - 0.25, - 4.60%). Louis Dreyfus Co, a world-famous food trader, has established a blockchain technology project in cooperation with Dutch and French banks. Using this project technology, the transaction settlement is faster than traditional methods in the process of selling soybeans to China
diamond instry
De Beers Group, the world's most famous diamond company, has its own blockchain company and has started operation. Its purpose is to "establish a digital record for every diamond registered on the platform". Considering the origin of diamonds, the ethical standards of origin, and the risk of diamond quality, blockchain technology is a good choice, because every record of it is indelible, and it will ensure that the electronic data of each diamond is as permanent as itself
real estate transactions
currently, Ukraine is the first country to use blockchain technology to promote property transactions. Michael Arlington, the founder of techcrunch, a famous technology website and cryptocurrency player, remotely purchased and resold a real estate in Kiev through the smart contract of Ethereum blockchain. This transaction was completed by propy, a start-up company specializing in blockchain real estate transactions
fisheries
blockchain technology is now being used to support the development of sustainable fisheries. Illegal fishing is a common problem in this instry. The distributed ledger technology of blockchain provides a proof of the capture source, processing and sale mode. This "net to table" supply chain allows inspectors to determine whether the fish caught came from a human rights violation area or from a country affected by economic sanctions
art paintings
similar to diamond trading, the art instry relies on the provenance and authenticity of art works. Although the blockchain cannot identify whether a painting is an original or a fake, it can be used to prove the identity of the previous owner of the painting. In addition, blockchain technology is now also used as a means to obtain works of art. It can make tangible goods easily traded and exchanged anywhere in the world without physical transfer from a secure storage place
public facilities
in Freemantle, Australia, a project dedicated to distributed energy and water system management is using blockchain technology, and solar panels (3.340, - 0.06, - 1.76%) are being used in sunny areas to obtain electricity, which is then used to heat water and provide electricity, All these energy conversion and use information will be recorded in the blockchain data
in Chile, the National Energy Commission has started to use the blockchain technology as the verification of the country's energy use data, and some sensitive data will be stored in the blockchain. The application of this technology can be regarded as a means for the modernization and safe operation of power infrastructure in this South American country
LGBT rights
blockchain can help build a "pink economy" and help LGBT communities fight for their own rights without revealing people's identities. This is an extremely important issue, because crimes of discrimination against homosexual groups often occur, especially in countries notorious for human rights violations, Homosexuality is illegal, or at least not allowed
catastrophe bonds
catastrophe bonds may be the only hope for victims of earthquakes, tsunamis and other natural disasters. Blockchain allows fast and transparent reconciliation between the parties, and can ensure that the system can continue to operate normally even under unmanned operation. Now, blockchain has been successfully used in the settlement mechanism of catastrophe bonds
tourism
local institutions in Hawaii are studying how to use blockchain technology to improve the economy, such as opening bitcoin and other monetary payment means to facilitate tourists' transaction of local goods and services. In this way, the Hawaiian government hopes to attract tourists, especially those from Asia, to spend more money in the local area and improve the economic development of Hawaii
homeland security
in 2016, the US Department of Homeland Security (DHS) announced a project that will use blockchain technology as a means of secure storage and capture of data transmission. DHS uses Factom's blockchain technology to encrypt and store data captured by security cameras and other sensors. The application of this blockchain technology will greatly rece the risk of data leakage. At present, the project is still in progress
maritime transportation
it is self-evident that blockchain is used to record ship transportation data. At present, some local shipping projects have adopted distributed ledger technology. In the maritime logistics instry, blockchain technology can make the inevitable cumbersome management proceres in international trade more transparent and orderly. Maersk, one of the world's largest shippers, is a pioneer in the use of blockchain. Today, Yixing international shipping company Zim has also made follow-up use of blockchain technology.
Sharing area network:
the application scope of blockchain technology is still very wide. Based on the characteristics of decentralization, distrust, collective maintenance and reliable database, its application in the financial instry is the first step
blockchain is the underlying technology of bitcoin, and the application and development of blockchain in digital currency is mature
like the block chain based trading system development scheme provided by Yingtang Zhongchuang, the developed software system has great safety factor and transparency
When it comes to offshore companies, they usually choose to register in the islands. Some domestic giants, such as Ali, tengxu, Shanda network, Xiaomi and Haidilao, set up overseas IPO structures by registering offshore companies in the islands
advantages of offshore companies registered in the islands:
1. Full tax exemption system (only a small amount of annual management fee)
2. Company information confidentiality (high degree of confidentiality)
3. Overseas IPO structure (Tencent, Xiaomi and other domestic giants build overseas IPO structure by registering offshore companies)
4. Freedom of name (Chinese can be added)
5 No foreign exchange control
6, no specific business scope, as long as not engaged in illegal and criminal activities or need to franchise instry
Second, the non-profit foundation of Singapore can issue relevant legal opinions to prove that the operation of the company is in line with the current laws of Singapore The main contents of the legal opinions are as follows:1. White paper modification: the white paper of the project shall be modified where it does not comply with the laws and regulations of Singapore, and a professional legal compliance opinion shall be issued by a lawyer
2. Token non securitization certificate: the lawyer issued a professional legal opinion to clarify in detail that the token issued by the project does not have the nature of securities
project valuation in round a and beyond: build your valuation model according to your income, proct, market, instry competitiveness and other factors, and give your project a relatively scientific valuation through the model, which needs professionals to do
the nine dimensional business plan is dedicated to "making a good business plan for 100000 visionary enterprises."
you can write a "blockchain project white paper" or a "business plan" according to a resource you have, and then find the relevant blockchain DAPP development company, or find the technology R & D team with blockchain application to help you develop the blockchain application you want
here, you should pay special attention to the fact that you can't easily introce your "business plan" to others, in case they imitate and develop similar projects. In this way, your advantage will not exist. You can also sign a "confidentiality agreement" to let the other Party keep secrets before development, and then you can give the specific requirements of the relevant procts and the price to pay.
1. Technical language
Python and go are two technical languages mentioned by many companies. Learning needs to be a priority. Moreover, these two languages have great application in the technical direction outside the blockchain. For example, go is used in the background construction of large concurrent systems, and Python is used in the construction of artificial intelligence systems. So learning these two languages is a priority
2. Technical framework
master one or more of bitcoin, Eth and hyperledger. Needless to say, BTC is written in C + +. A large number of currency projects, such as lightcoin, dash, Monroe, zcash, use bitcoin technology for secondary development
eth is the representative of blockchain 2.0, which can build a variety of application classes DAPP on eth network. Now a large number of application blockchain projects are developed using eth platform
hyperledger fabric is a blockchain development platform pushed by IBM, which is mainly used for the development of alliance chain, and is the most popular alliance chain development platform at present
3, algorithm
pow (proof of work), POS (proof of rights and interests algorithm), pbft (Byzantine fault-tolerant algorithm) are all important components of cryptography in blockchain. A full understanding of these algorithms will help you to have a better understanding of cryptography when you participate in the underlying development of blockchain projects
extended data:
blockchain technology is a kind of Distributed Accounting Technology, which is characterized by decentralization, openness and transparency, so that everyone can participate in the establishment of the database, and each established data can not be tampered with, and everyone participates, The problem of trust between strangers is solved
blockchain technology has emerged. It is an accounting technology with the participation of the whole people. The transaction information and data between AB and ab are published to the public and can not be tampered with. As we all know, there is no need for any authoritative Third Party C here. In other words, everyone in the system plays the role of C, which is also called decentralization
2. It's easy to carry. It's convenient and safe to wrap the coin around the waist& quot; Inventory & quot; This is the origin of the word
ancient coins are metal coins with holes in the middle. A thousand coins are usually hung up in a string with ropes. The rope through which the coins are put is called "Guan". Therefore, a thousand coins are also called "hanging money" or "consistent money". When people go abroad to visit their relatives, they can only bring heavy strings of copper money. It is convenient to carry and patrol the whole coin by winding it around the waist. Therefore, the ancients called the travelling expenses "winding"
3. There is a reason to be a man. Copper coin is a kind of external and internal way, and so is the need to be a man. He is smooth in his work, but upright in his heart.
recently, people's daily commented on the hot topic "community group buying" . The commentary points out that there are many different voices in the public opinion field now, "in addition to the discussion on the profound changes in the interests of the vegetable vendor group, there are also many thoughts pointing to the innovation expectations of large Internet enterprises."
the comments said that the Internet giant with massive data and advanced algorithms "don't just think about the traffic of a few bundles of cabbages and a few catties of fruits. The star sea of scientific and technological innovation and unlimited possibilities in the future are actually more exciting."
{rrrrrrr}
extended data
community group buying has become a hot spot in the air:
in June this year, the community group buying brand "orange heart preferred" incubated by didi was officially launched. At present, its service scope has covered seven provinces and cities, including Sichuan and Chongqing, and will develop nationwide in the future. Then, meituan's "meituan preferred" was launched in July. In a short period of three months, it has laid out more than 20 cities and expanded the number of community group buying staff to 1000
at this moment, pinoo is not lonely, so it launched "Duoo shopping" in August. In two months, it covered more than 60 cities. It's no exaggeration to say that it's just like a miracle of development in the past
as for Jingdong, it was first reported that Jingdong youyou would soon go online, and then it recently acquired Meijia Maicai, a subsidiary of meicai.com. We have to say that Jingdong has a strong sense of crisis
it can be seen from here that with the rush of giants, community group buying has changed from the oil bottle of that year to the fragrant cake under the wind. In addition, after decades of hard work, community group buying has become mature and stable from being young in those years
