1. What is blockchain? Application of blockchain technology
what is a blockchain? In essence, blockchain is a decentralized distributed ledger database, which is the underlying technology of bitcoin, and is associated with bitcoin. The blockchain itself is actually a series of data blocks generated by the use of cryptography, each of which contains the information of effective confirmation of multiple bitcoin network transactions
whenever an encrypted transaction occurs, miners with strong computing power in the network begin to use the algorithm to decrypt and verify the transaction, creating new blocks to record the latest transaction. New blocks are added to the end of the original blockchain in time order, and the account book will keep growing and extending
through the complex setting of public key and private key, the blockchain network will broadcast all the transaction books of the whole financial network in real time, distribute the transaction records to each client in real time, and ensure that everyone can only modify their own property. Of course, there are other people's transaction records in the account book. Although you can see the numerical value and the corresponding transaction address (which is basically composed of a long piece of disordered letters and numbers), you can't know the real identity of the trader without using other technical means
what is a blockchain? Since last year, the concept of blockchain has become popular, especially in some developed countries. Blockchain is also known as subversion, which is very popular all over the world. Blockchain will be the first to impact the financial instry, and then will affect a wider range of economic fields. The prediction is based on several core characteristics of blockchain: decentralization, distributed ledger, point-to-point transmission, tamper proof, etc. Because the birth of blockchain is quite magical, and its development is also concerned with the rise of bitcoin in the world, many people will confuse the relationship between blockchain and bitcoin. Some people think that blockchain is a parent-child relationship with bitcoin, while others think that blockchain was born after bitcoin. But in fact, blockchain is the underlying supporting technology of bitcoin, which can be compared with TCP / IP protocol in the Internet. From a certain point of view, bitcoin can be regarded as the first practical application of blockchain generated simultaneously with blockchain
Application of blockchain technology? Since its establishment, Bubi blockchain has been focusing on the R & D and innovation of blockchain technology and procts. It has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technological achievements, such as: mathematically proven distributed consensus technology, fast large-scale account book access technology, multi chain general ledger technology supporting business form expansion The interconnection technology between heterogeneous blockchains. On April 25, "gege integral" introced the integral system into the concept of blockchain, opened up by multiple parties, issued and exchanged integral, and promoted the circulation of integral. All cooperative institutions can jointly participate in transaction verification, account book storage and real-time settlement; The third-party payment platform of the enterprise points issuer makes the points in and out more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely
what is a blockchain? Application of blockchain technology? We can use bitcoin to describe several application prospects of blockchain. Bitcoin can be said to be a decentralized currency or asset. Every bitcoin can be traced back and found by everyone at any time. This application prospect means that if the transactions between people can return to the original form of barter from the current monetary value measurement method, then the measure of value is no longer legal currency, but bitcoin or other virtual currencies or virtual assets generated by the blockchain, The benefits of the current sharing economy are just the tip of the iceberg. If this traceability, query and tamper proof feature of bitcoin is applied to credit record system, identity authentication system or property right authentication system, many things like "is this house my property?"“ Whether I am unmarried or married "will not exist at all. According to the current development trend, blockchain will not only reshape all aspects of money market, payment system, financial services and economic form, but also change every field of human life.

2. IBM, Microsoft, Oracle, Accenture, Tencent, Alibaba, Jingdong, network, etc. have all done it. Many large banks, including Ping An Bank, have also launched their own blockchain solution platforms or solutions. However, it should be added that large companies do not mean strong technical strength, because blockchain is still in the hot stage of concept in the world. Unicorn blockchain companies are likely to emerge in the future, such as EOS in foreign countries and honeycomb chain of Fanrong technology in China. The efficiency of TPS and packing into blocks may be much higher than that of large companies.

[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

To select a proct traceability system, we must select a block chain traceability system
because blockchain is an open, transparent and tamper proof technology, it has great credibility for information fidelity. Compared with the traditional centralized traceability system, which is vulnerable to hacker attacks and causes poor system security and stability, the decentralized blockchain technology has absolute advantages, and the well chain traceability application is the real blockchain technology
mokejing chain has been committed to blockchain technology for six years. At the same time, mokejing chain has been carrying out the implementation practice of blockchain technology application, and has jointly built various blockchain technology application platforms with major enterprises, including business intelligence platform, smart city platform, anti-counterfeiting traceability platform, etc. Every application platform makes full use of blockchain technology to solve all kinds of pain points of traditional Internet platform, making the platform more reliable and authentic, and deeply loved by enterprises and users. The well chain traceability platform is highly praised and recommended by many enterprises
well chain traceability optimizes one thing and two codes on the basis of one thing and one code, which makes the query information more comprehensive and traceable; Anti counterfeiting one-to-one locking, implicit anti-counterfeiting code accurately corresponding, can be used for anti-counterfeiting, anti-counterfeiting, traceability, code scanning marketing, data analysis, private customized one-stop service, help enterprises solve the problems of proct traceability, anti-counterfeiting and anti channeling, brand image and so on
5. Concentric mutual aid, founded by blockchain start-up company Abbott, is a network mutual aid platform applying blockchain technology, and also the first real blockchain landing application in China. Concentric mutual aid combines open source code with practical application, realizing the deep matching between blockchain technology and network mutual aid
e to the technical characteristics of blockchain, concentric mutual aid has three characteristics: first, all capital flows are open and transparent, which can not be forged or tampered with, and each user can exercise the right of supervision. Secondly, the transfer of all funds can only be carried out in accordance with the open smart contract, and there is no legal person for misappropriation and intervention. Finally, each user's personal sensitive information will be highly encrypted, and no one else can access it. Based on the above three points, the problems existing in the traditional network mutual aid mode have been solved one by one. In addition, in order to ensure the authenticity of the payment, the new "jury" system has been established in the supervision mechanism, which forms a professional identification system with lawyers, doctors, judges, police and other public officials, so as to ensure the authenticity and reliability of each payment, and completely eliminate the most critical defects of traditional network mutual assistance.

9. First of all, these two are virtual assets. The price of these two kinds of digital currency, or a specific price of digital currency, is determined according to the market situation
the details of these two digital assets are as follows
bitcoin (bitcoin: bitcoin) was originally a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals
the full name of NMC is "new media chain", the Chinese name is media chain, and the former domain name currency (also referred to as NMC) is two completely different currencies. NMC is the circulating currency of three decentralized application platforms: coin call [blockchain information community portal], coin search [blockchain network query tool], ncoin [digital currency exchange]. However, the prices of these two kinds of digital currencies will fluctuate with the market, which can not guarantee a development prospect. If the current price is concerned, bitcoin will be a bit higher.
