Blockchain business of HUAFA

Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

if such technology wants to be put into application, the biggest problem is the "Impossible Triangle problem"

that is, scalability, decentralization and security cannot be achieved at the same time, and only two of them can be achieved

most of the existing public chain projects in the market are difficult to put into use on a large scale

3. What blockchain makes money now is only cryptocurrency such as bitcoin, and it's very difficult to make money by mining. Nowadays, there are many deceptive routines in the name of digital currency. There are some things you don't need to know so much about. Even if you understand, you can't make money.

4. Shandong bianke Information Technology Co., Ltd. is a software development company with excellent technology
[blockchain exchange]
blockchain technology application research and development, exchange wallet system app development, blockchain technology is actually a new type of Internet. Why is it a subversion of the Internet? Because the Internet solves the problem of information transmission, and the blockchain solves the problem of value transmission. Yuanzhongrui's blockchain system has a lot of value transfer in the development of blockchain, such as distributed ledger, decentralized trust, smart contract, etc. What kind of society will it build in the future
the answer is: a distributed business and self disciplined society. Blockchain features first, decentralization; Without the intervention of the third party, it can realize people to people, point-to-point transaction and interaction
Second, information can not be tampered with; Once the data information is written into the block, it cannot be changed or revoked< Thirdly, it is open and transparent; In a very short time, the block information will be copied to all the blocks in the network to realize the data synchronization of the whole network, and each node can trace back all the transaction information of both sides in the past
Fourth, collective maintenance; In the whole blockchain network, all roles work together to maintain the reliability and security of the whole blockchain information
fifthly, reliable database; Only by mastering 51% of the nodes of the whole system can we tamper with the blockchain information, which is obviously impossible, because there are many participants in the whole system, and mastering so many nodes can not be realized at high cost
the characteristics of blockchain bring great opportunities for the financial instry. With the help of blockchain, the transformation of the internal application scenarios of the instry can bring three main benefits:
1) cost rection: communication cost: the centralized trading market generally needs the participation and coordination of the central clearing system, securities companies, exchanges and banks, and the coordination cost is very high, Through the signature and encryption technology of blockchain, the information can be shared and the coordination cost can be reced; Operating costs: recing labor and paper vouchers, improving automation through smart contracts, and centralizing coordination also bring very high operating costs
2) improve efficiency: the settlement cycle is very fast. When the financial transactions realized through blockchain technology are confirmed, they are actually the process of combining clearing, settlement and audit. The openness, transparency and non tamperability of the blockchain can preserve the operation traces, keep the supervision records and audit traces, and provide convenience for supervision and audit
3) risk rection: the transaction confirmation on the chain is the completion of clearing and calculation, which greatly reces the transaction risk. The research and development of blockchain technology application and the development of exchange wallet system app

The first sub chain of ETO public chain, Jingniu chain, is coming online soon, helping the entity enterprises to enter a new era of "blockchain +"

blockchain has been born for more than ten years. In recent years, with the increasingly mature blockchain technology and the continuous enrichment of application scenarios, blockchain has attracted more and more attention. In particular, on April 20 this year, the national development and Reform Commission explicitly proposed for the first time that the blockchain should be included in the scope of China's "new infrastructure". Blockchain has become a key technology to enhance the efficiency of China's stock assets and improve the competitiveness of medium and long-term instries

the significance of chain reform? In essence, through the consistent distribution and rendant storage of data in the whole network, blockchain realizes the openness, transparency and non tampering of data, reces the information asymmetry at the system level, and enables nodes to reorganize business relationships based on new information acquisition capabilities. While the information system of blockchain is decentralized, the overall efficiency is improved by constructing the decentralization of business system and the disintermediation of business process

the essential requirement of real economy reform is to rece cost and increase efficiency. The purpose of developing digital economy is to serve the real economy, and blockchain plays an extremely important role in this process

on the one hand, the so-called "chain reform" is to reconstruct and reorganize the business process of the real economy through the blockchain, and realize the distribution and storage of data on the chain with decentralized business system and disintermediated business process; On the other hand, through the introction of token economy, we can adjust the interest structure of different subjects in the business system, improve the value flow efficiency of the whole supply chain system, and reconstruct the interest distribution model. That's why chain reform is so important

from the technical level, the chain reform can solve the problems of trust, security, privacy protection, cost rection and efficiency through application, information and assets. From the perspective of token economy, chain reform can change the way of economic value output, circulation and distribution, so that all contributors of the whole ecology can get corresponding returns for their own efforts

the chain reform transforms the identity of "consumer" into the identity of "consumer + communicator + investor", transforms the interest pair into the interest community, and improves the stickiness of terminal consumers; Through the design of incentive model, the proction relationship can be liberated, the collaborative value of the upstream and downstream of the supply chain can be improved, and the benefit can be maximized. In the long run, chain reform is of great significance to the development and progress of the whole society and the promotion and protection of personal income

Jingniu chain, which focuses on one-stop chain reform service, is the world's leading one-stop chain reform service platform focusing on real economy chain reform and digital equity of real enterprises. On the one hand, Jingniu chain is committed to help small and medium-sized enterprises solve the internal and external incentive problems through blockchain technology, obtain immediate incentive feedback internally, and improve the efficiency of upstream and downstream collaboration externally; According to the proct characteristics of different enterprises, personalized chain reform scheme is provided to enable enterprises to obtain differentiated competitive advantage

the specific destruction mechanism is as follows: 5% of the amount is always released every day as the destruction pool, and the explosion report mechanism is used to return to the participants. The miner needs 3% equivalent ETO (platform token of ETO equity public chain) as the miner's fee to participate in the explosion report, and the mine pool will get random returns of 2 times, 3 times, 4 times and 5 times according to the destruction amount, The money returned by the miner will be released by 2% of the balance per day until the amount of the destroyed ore pool has been exploded. The amount of money that has not been exploded on that day will be deposited in the destroyed ore pool

in terms of miner's fees, 3% ETO of equivalent value is required for pledge or withdrawal of currency JnL as token, and 0.3% ETO of equivalent value is required for transaction and transfer as handling charge

in addition, 3% of daily proction will be converted into 1% charity fund, 1% Tourism Fund and 1% learning fund respectively

As the world's leading service platform for chain reform and digital equity, Jingniu chain not only has the world's top team, covering the landing cases of chain reform and digital equity service in many instries, but also can provide services such as all-round and multi-channel promotion and operation, investment and merger, digital equity transformation, listing and circulation transaction, JnL, as the circulation medium of the value bearing capacity of the whole ecosystem, plays an important role

in the future, as more and more small and medium-sized entity enterprises realize the importance of blockchain and the continuous development of the chain reform platform represented by Jingniu chain, more "blockchain +" instries will be launched, and the global entity enterprises will enter a new era of "blockchain +"

6. Blockchain concept:
hailimeda (25.99 + 0.89%, buy) has become a leading mobile information service and third-party payment provider in China through M & a linkage advantages, entered the first echelon of A-share mobile payment, and formed a unique mass data base, which is expected to become one of the earliest financial service companies to lay out blockchain in China. Although the company's answer to the market rumor that it is involved in the blockchain technology instry is "so far, it has not been included in the main business", it seems to be optimistic that the company is involved in this field according to the research reports of many securities companies
Hang Seng Electronics (62.30-0.73%, buy) is trying to establish a digital bill system based on alliance chain by using blockchain technology

In the past week, blockchain concept stocks have set off a wave of speculation in the A-share market. Indivial stocks have been trading continuously. Dozens of listed companies have issued announcements one after another. Some have clarified the relevant business, while others have "rubbed" the blockchain concept intentionally or unintentionally

In addition, dozens of companies, including Aikang technology, Donggang Co., Ltd., Shenzhou Taiyue, Hailian Jinhui, Bosi software, have also issued announcements. Wind statistics show that since the beginning of this year, the wind blockchain concept index has increased by more than 15.89%. In the overseas market, stocks involving the concept of blockchain soared overnight. On January 4, china.com.cn announced that it would carry out the application of blockchain technology. The stock surged 698% overnight. Taking 2018 as the interval, the cumulative rise of the stock has reached 340.37% in just nine trading days

it is learned that although the instry generally recognizes the potential of blockchain technology, many A-share listed companies are still at a relatively preliminary level. As for the market's speculation on the concept of blockchain, in the past week, the Shanghai Stock Exchange has successively sent inquiry letters to Shangying global and youjiu game, requiring them to disclose the research progress, commercial application scenarios and profit models of blockchain technology, and fully remind investors of the risks in combination with the current market-oriented and commercial maturity of blockchain technology

8. 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."

9. Blockchain technology is called distributed ledger technology

10. Suppose 10 yuan x pieces, then 5 yuan is (45-x), according to the meaning of the title,
10x + 5 (45-x) = 350
10x + 225-5x = 350
5x = 125
x = 25
so 10 yuan is 25 pieces, 5 yuan is 20 pieces.
