Blockchain project development contract

1. It also depends on what kind of blockchain app you develop. A simple one can be done with thousands of yuan, and a complex one can be done with tens of thousands or even hundreds of thousands of yuan

2. Blockchain assets are the most popular investment varieties in recent years. Some quantum chain crowdfunding has increased by 30 times, some Dao has been dismally delisted e to hacker attacks, and some ant stocks have increased by 1000 times in three years! How on earth should I vote? Experienced circle bigwigs all support a kind of investment mode: fixed investment + decentralized allocation
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!

3. Go is an open source programming language, which makes it easy to construct simple, reliable and efficient software. If you want to learn this programming language, you should first find a good tutorial. Brother Lian's go language + blockchain training has recently published a new set of go language tutorial, and the teacher's speaking is very good

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

4. If you have your own technology, you can develop it yourself. If you have money, you can hire people to develop it.

5. As we all know, there are many blockchain projects. The common ones are: mobile phone mining, digital currency development (token), digital currency exchange, digital currency wallet, blockchain mall, blockchain pet cultivation, blockchain games...
blockchain development needs to be determined according to the development methods and functions. Customized development is expensive, and it will be very expensive if there are many and complex functions, Therefore, this specific price can only be expressed in a specific scheme.

6. The second type of blockchain projects is platform type. What are the characteristics of platform type blockchain projects? What are the typical representatives
the second category of blockchain projects is platform. The main function of platform projects is to establish a technical platform to meet the technical requirements of various blockchain application development
in short, platform applications allow developers to directly issue digital assets and write smart contracts on the blockchain. Smart contract is a computer program running on the blockchain database, which can be executed by itself under the condition of meeting the source code setting
for example, you develop a smart contract based on the house rent protocol on the blockchain. When the owner receives the rent, it will trigger automatic execution and give the security key of the apartment to the tenant
the main function of platform blockchain projects is to establish the underlying technology platform, so that developers can do application development on the underlying technology platform. A considerable number of platforms are still in the development state. As of January 2018, Ethereum has the largest market value.

7. Early Enterprise Valuation: basically according to the fair market price, you can refer to the general valuation of the projects that have been financed, and then according to your judgment, you can give yourself a reasonable valuation, which is basically a pat on the head; If you plan to finance 5 million yuan and sell 20% of the shares, the pre investment valuation of your project is 20 million yuan, and the post investment valuation is 25 million yuan
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."

8. " Let's take a look at the keynote speech entitled "the era of instrial community has come" delivered by Wu Ting, founder of guest University and procer of "I have guests". In her speech, Wu Ting first mentioned "instrial community", which is a new force to promote China's economic growth, and gave six characteristics of the times of instrial community:
1. Technology empowerment and cross-border cooperation
not only Xiaomi and Tencent, but also iFLYTEK has a developer's festival. IFLYTEK's open platform is open source technology, shared with 450000 entrepreneurs. Every day, 4 billion people use iFLYTEK's open technology, which is technology empowerment and cross-border cooperation. Mr. Liu Zihong is building the "flexible +" platform of Rouyu, which is also a typical example from technology enabling to cross-border cooperation
2. Be yourself and practice internal skills
What are we going to do? We should be ourselves and practice our internal skills. As long as you make the best of what you are good at, you will have "core competitiveness". In the past, it was said that we should make up for our shortcomings. Today, the shortcomings are not important. If everyone makes his own long board, he can make the container higher
when he was young, his parents wanted him to become a writer and painter, but his works were evaluated as "no room for shaping" by his teachers. Later, his chemistry teacher discovered his talent. After training, walach won the title of doctor of chemistry at the age of 22, and finally won the Nobel Prize in chemistry
everyone has his own short board. As long as he finds his best position in life and gives full play to the potential of the long board, he can achieve the most amazing results, which is the "Wallach effect". This is the way to be a person, an enterprise and an investment
let me give you an example. There is an investor in Shenzhen who has invested in the consumer instry for more than ten years. He has invested in Zhou Heiya, Baiguoyuan and Naixue's tea projects. Although he is famous today, more than ten years ago, everyone thought that the things he invested in had no room for imagination, and PE was very low, that is, he opened a shop to do business. But he persisted, and has been doing insight, understanding, and research in this instry to invest in projects. Up to now, he has become the top investor in the field of consumption, and has gained in-depth thinking of the instry. This person is Feng Weidong, the managing partner of Tiantu investment
it needs to be hard to forge iron. If you do it well, everything will follow, facing the heart and blooming in spring. To be good at yourself is the most powerful thing
3. Quality revolution and ingenuity return
why does Japan have such a good consumer service instry? Because Japan's economy has been in a downturn for a long time, and the Japanese market is very small, everyone has the opportunity to stand out and be bought by consumers only when they make their procts the best
some people say that it is a good time to get the bottom of the stock market and the real estate market, but I think it is also a very good time to get the bottom of the life. Chen Biao, a senior journalist, once said that we should not forget why we started just because we have gone too far. In today's adjustment period, we have the opportunity to calm down and think about why we want to start a business? What purpose and effect do I want to achieve? Many people around me are already thinking about this
as an interesting example, since our company was founded nearly three years ago, I have not been able to recruit a particularly good editor, because the first group of editors went to Party A as a brand, and Party A had more money and less work; The second group, because we media has risen, many people have gone to work in US media. Now we media is nothing but chicken feathers, and few people can survive tenaciously; The third group of writers have gone to do blockchain media. In my understanding, many blockchain media are public relations media, but who makes it profitable. Later facts have proved that many of them have been shut down
in the face of a phased downturn today, when everyone is thinking about what I am best at, I think the quality revolution may be based on the return of ingenuity, and each of us should think about what we can do and what we can do well
I believe I can recruit a good editor in chief soon
4. Consensus mechanism, rule first
everyone is talking about blockchain today. I made a documentary about three or four years ago, the group dance of black bees. At that time, I was the only filmmaker of wildlife documentary in China. After shooting, because of its uniqueness, this work also won many awards. I would like to make this point: a bee is an insect, and a group of bees are mammals. The work of bees is unconscious and distributed, but the colony has formed an organic function and brought about the reproction of the population. Later, some people described blockchain as honeycomb thinking, which I very much agree with
from the hunting age to the workshop age, from the instrial age to the information age. Every progress of human society comes from the upgrading of cooperative relationship
blockchain has removed the transaction mode based on "organization" link and established the transaction mode based on "person" link. Blockchain technology + Tongzheng economy + community = instrial community. Instry + blockchain, based on the public account book, can make the information symmetry, trust symmetry, resource allocation, cost-effective management, and efficient capital flow of all cooperative entities in the instrial ecology, optimize the proction relations, and fully release the proctivity of workers
5. All things accelerate their evolution, and the only constant is change
why was I the only one who made wildlife documentary at that time? Because it doesn't make money, the price of this film is about 1 million yuan. I shot it for 700 days. After shooting, the company won a lot of awards, but it soon went bankrupt. Today, when I was making a commercial documentary, I didn't dare to do it with such a rhythm
some time ago, we photographed the short rent of piglets. They don't start a business for a long time. When they start a business, their benchmarking is airbnb; At the end of last year, his target was the hotel; Last week, when we went there to visit students, he said that we should do instrial Internet, from information flow to service flow
in this era, the only constant is change. There was a joke in the past that "the only constant for women is fickleness". In fact, in this era, I think the ability to deal with complex situations is one of the most important core competitiveness of founders. Change is to seek death, change is to wait for death. The person who chooses to seek death between seeking death and waiting for death must be an entrepreneur
Bill Gates once said: people always overestimate the changes in the next year and underestimate the changes in the next 10 years. Chen Chunhua once said: in the future, enterprises will only focus on growth rather than success, regardless of size. Xiaomi's Liu De also said: do a good job in this year and arrange for next year. I didn't expect to fall like this when I rang the bell. Zhang Liaoyuan of three squirrels also felt deeply about this: I don't set any goals now. I used to like setting goals, but today I only dare to set goals for next month
every year "I have guests" interviews 500 guests to learn about their cases. We have made nearly 100 programs, reaching 350 million high-end people. The theme of this season is "I have guests - the story of the reformer.". The story of death and posterity is particularly moving. Companies that have never been able to survive are not able to have the motive force of free growth
on the other hand, the guest university does not have the physical wall, nor the shackles of thinking. It has global pattern, seeking change and following reality, opening up knowledge, linking value, dynamic cognition and elite dialogue
it's very meaningful for us and students to go into each company and explore their ups and downs, to feel their changes, their ability to cope with changes, their ability to deal with crises, and to feel life and death with them
Jobs said that he was willing to exchange his life's wealth for the opportunity to talk with Socrates. That is to say, we are going to meet Socrates one by one. We are going to talk with Mr. Fang Hongbo of Midea about how they are going to upgrade from a home appliance benchmarking enterprise to an intelligent instry; Talk to Cai Xiaodong of aofei about how they have changed from a toy factory to an entertainment IP magnate; Talk with Uncle Kai about how they have become the first brand of children's ecation from audio programs; Talk with Mao Daqing about how real estate turns to entrepreneurial services; He also talked with Jiang Xipei of Far East Group about his four survival changes
6, the city is a super instrial community
instrial community is not only the development path that enterprises should take the initiative to explore, but also the development direction of the city. The concept of city that I know is not necessarily a city, but also a district, a small town or a province. Of course, given the concept of "smart city", the instrial community can do better
a benchmark is Shenzhen, where we live today. In 2017, about 70% of the intelligent hardware in China came from Shenzhen. Shenzhen has all the resources and conditions from hardware design to procts. A hardware entrepreneur from Silicon Valley yelled, "here we can find any raw material we want within one kilometer, which is impossible in the United States, Europe and anywhere in the world, because there is no Huaqiangbei in Shenzhen."
Shenzhen provides a very natural convenience for entrepreneurs. There are many great enterprises in Shenzhen, such as Huawei, oppo and youbiexuan. They are all brought up by the fertile land of Shenzhen. There are two kinds of entrepreneurs, Tianpai and Dipai. Tianpai is an Internet entrepreneur; Di Pai is more early entrepreneurs in Shenzhen. They open factories, have their own proction lines, and do things in a down-to-earth way
lack of instrial landing coordination, Internet, app and innovation are "castles in the air"; Lack of technological innovation and upgrading, "local entrepreneurship" will always be the labor force at the end of the instrial chain
only the combination of heaven and earth can we innovate and upgrade and create a better life for us& quot;

9. Now the hot blockchain project is virtual currency investment, such as the realm Kingdom, which mainly provides investors' favorite up and down trading methods, and provides a variety of trading methods to meet the trading needs of customers' webpages, mobile phones and app ports.

10. 1. The square hole copper coin should be said that the heaven is round and the earth is square. In ancient times, people thought that the heaven was round and the earth was square, so Qin Shihuang's coin was made in this way
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.
