Leading blockchain technology breakthrough

1. 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

2. Before, blockchain had many disadvantages. It is too transparent, so that the flow of assets lost its e secrecy and security, which will easily bring the loss of assets to the participants. However, on the basis of the original blockchain, DERO optimizes the intelligent contract, improves the privacy and security, and avoids the operational risk caused by the data disclosure of the participants. Currently, DERO coin has been on the coin dragon online line.

Because the blockchain technology is not mature at this stage, and the infrastructure is not perfect, many applications are limited, and the overall application is still in a very early stage

First of all, the main function of blockchain is to store information. Any information that needs to be saved can be written to or read from the blockchain, so it is a database. Secondly, anyone can set up a server and join the blockchain network to become a node. In the world of blockchain, there is no central node (decentralization). Every node is equal and keeps the whole database. You can write / read data to any node, because all nodes will be synchronized in the end to ensure the consistency of the blockchain

4. 1) First of all, it defines the technical value and positioning of the blockchain. As I said at the beginning, the positioning of the blockchain should take the blockchain as an important breakthrough for core technology and independent innovation
2) blockchain, Internet and artificial intelligence should be regarded as technologies of the same height, and blockchain should formally enter our hard science and technology development category
3) pointed out the development and application direction of our blockchain, including the speech that the technology of blockchain has extended to many fields, such as digital finance, Internet of things, intelligent manufacturing, supply chain management, digital asset trading, and so on. In terms of application, there will inevitably be some regulatory or legal problems in the process of application, What are the instructions in this speech? He mentioned that we should implement the rule of law in the management of blockchain, and promote the safe and orderly development of blockchain
4) in the more important point of application and development, it is mentioned that the blockchain is from virtual to real, enabling entity, improving people's livelihood, obtaining instrial advantages, and better serving the development of the whole instrial economy. In fact, through the study of blockchain technology, from one side or the signal released, we express our attitude towards the innovation and leadership of blockchain. We hope that in the development of blockchain, we can first have our own core technology, and we should be a leader in today's fierce international competition
5) it is to enhance the market confidence of the whole blockchain instry, especially for the application and development of the whole blockchain technology. With a great increase in market confidence, it is bound to attract more people in the next period of time, including the capital market and for example, more talents and research applications will enter this field. More capital, more manpower and more other social related aspects, including the rule of law and legislation, will positively promote the application and landing of the whole blockchain technology. These are my four points of view or summary of blockchain technology learning
if you have been concerned about blockchain for a long time, in fact, from the national level, including the 13th five year plan, blockchain technology has been written into the 13th five year plan, which is developed as a parallel technology with artificial intelligence, big data and cloud computing. It has been introced in the second half of 2018, and the office of network information technology has put the blockchain application service on record, From all aspects, it is actually a positive guidance or protection for the development of the whole blockchain
of course, when it comes to blockchain, you may also say that blockchain always thinks of money speculation and so on. In fact, digital currency is only a relatively narrow field in the field of blockchain. We now include support from the mainstream of modern society or the national level, and more support for the application of blockchain technology in the real instry, The core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in the distributed system without mutual trust by means of data encryption, timestamp, distributed consensus and economic incentives, so as to solve the common high cost and low cost problems of centralized institutions Low efficiency and data storage insecurity provide solutions
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.

5. Safety still needs to understand the platform carefully, including the risk control measures of the platform. As long as you want to choose a bank deposit, performance insurance, but this is for investment.

7.

In our lives, we create an unprecedented amount of data. From social media to digital footprint, we use services such as Netflix, Fitbit or networked systems. Every second, 900000 people click on Facebook, 452000 log on to twitter, and 3.5 million use Google search

this happens so fast that the amount of data now doubles every two years, and this growth (and the opportunities it provides) is what we call big data

the absolute value of this data means that an instry and an enthusiastic, non-commercial driven community develop around big data. Just a few years ago, however, only large companies had the resources and expertise to take advantage of this scale of data. The shift to a "service" platform has reced the need to spend heavily on infrastructure. The explosion of data makes many other trends possible today, and learning how to use it will increase the prospects of anyone in any field

8. For your problem, its coverage is too large and profound! At present, the existence of QQ coin and all network virtual exchange items is to make the company
profitable, and its cost can not be superficial. Who knows or stipulates how much a hat and a dress in QQ embroidery are worth? How much do I sell
it is not the same as a real commodity
you need to estimate its value and how much benefit it can bring to employees. No matter how to determine its cost, it is also virtual. In principle, as long as I meet my
profit goal, this is its cost! It's hard for such a huge system to analyze experts, not to mention you and me? I have a brief understanding as follows

first of all, in Tencent, q-coin virtual transaction phenomenon, a variety of payment means of goods have been derived from a single commodity consumption payment in disguise.
when it is used as the equivalent exchange virtual circulation in the way of RMB, he already has the concept of currency, as a value measure, which is
the intrinsic value measure of goods, In Tencent's website, q-coin can be used to buy virtual goods, such as a virtual QQ show clothes is better than a few q-coins, a virtual avatar is also better than a few q-coins, senior members can use q-coin to pay es, a senior QQ group needs 30 q-coins every month. Q-coin and other virtual currencies can not only purchase various network services provided by their own home, but also purchase network services provided by other enterprises on the Internet, such as Jiangmin antivirus software and other popular software on the network

with such a premise that interests cover a wide range and profits are rampant, all kinds of activities of q-coin trading become more and more interesting

on taobao.com, the seller's quotation for RMB to q is 0.5 yuan to 1q yuan, and the buyer's quotation is generally 0.45 to 0.47 yuan to 1q yuan in private. In addition, the method of purchasing q-coin has been simple

from dealers. It has developed to be able to apply for q-coin with face value of 1

, 2, 5, 10 yuan each time by dialing voice phone or mobile phone, which is equivalent to 1, 2, 5, 10 yuan dected from the telephone fee# Then how to get the source of goods at a low price, there are some new problems, such as the current market price of the serial number is 10000 numbers. If it is first-hand, the price is about 220 yuan. Then we can check the number through the serial number tools: jqq, PQQ, etc. the machine is fast and the network is good. We can check more than 10000 numbers in an hour, Can automatically find out each number

how many Q coins, game currency, level, whether there is password protection, points and so on can be at a glance

generally only sell 1-9. Some people sell 1-4, 5-9 separately. The price is about 1-4.14 yuan and 5-9.23 yuan respectively. It can be said that Q coin has the most negative nature of

but it is not difficult to find that in the case of incomplete relevant laws in China, the hidden dangers can not be ignored

the above is limited to space, and I only talk about some rough and obvious things. I hope you can study them together!
