4. Blockchain and blockchain technology have been widely accepted and used by people, but they have little knowledge about blockchain and blockchain technology, and they are even at a loss about the working principle and operation mode of blockchain. Perhaps I've read many related reports, many professional terms, and I'm not very clear about them. Here, I'll explain them in a popular way
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
this is usually the summary of the professional reports, but what is the specific form
first of all, no matter how large a system or how small a website is, there is a database behind it. So who will maintain this database? In general, who is responsible for the operation of the network or system, then who is responsible for the maintenance
if it is wechat database, it must be maintained by Tencent team, and Taobao database is maintained by Alibaba team. We must think that this way is natural, but blockchain technology is not
secondly, blockchain technology is also known as distributed ledger technology. If we think of the database as a Book: for example, Alipay is a typical account book, any change of data is bookkeeping. We can think of database maintenance as a very simple way of accounting
in the world of blockchain, everyone in the blockchain system has the opportunity to participate in bookkeeping. The system will select the person with the fastest and best bookkeeping in 10 seconds or 10 minutes, and the person will record the changes of database and account book in a block
we can think of this block as a piece of paper. After confirming that the records are correct, the system will link the fingerprint of the data in the past account book to this piece of paper, and then send this piece of paper to all other people in the whole system. Then, over and over again, the system will look for the next person with fast and good bookkeeping, and everyone else in the system will get a of the whole ledger
as like as two peas, each computer has the same rights as the owner, and the whole system will not collapse e to the loss of contact or downtime by a single person.
as like as two peas in the book, it means that all data is transparent and open. Everyone can see what changes are in every account. Its very interesting feature is that the data can't be tampered with. Because the system will automatically compare, it will think that the same number of books with the largest number are real books, and a small number of books with different numbers are false books
in this case, it is meaningless for anyone to tamper with his own account book, because unless you can tamper with most nodes in the whole system. If there are only a few nodes in the whole system, it may be easy to do so. But if there are tens of thousands and hundreds of thousands of nodes and they are distributed in any corner of the Internet, unless someone can control most computers in the world, it is unlikely to tamper with such a large blockchain
I don't know if I can understand such a popular explanation

5. Blockchain encryption algorithm
asymmetric encryption algorithm is a function that converts the original plaintext file or data into a series of unreadable ciphertext codes by using an encryption key. The encryption process is irreversible. Only holding the corresponding decryption key can the encrypted information be decrypted into readable plaintext. Encryption enables private data to be transmitted through the public network under the condition of low risk, and protects the data from being stolen and read by the third party
the core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the high cost and low cost 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.

6. 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.

7. How to realize blockchain? The current situation of global blockchain development is also more and more enthusiastic, which shows that blockchain is widely used all over the world, has more and more powerful vitality, and affects all walks of life from the outside to the inside. The current situation of global blockchain development has a very good atmosphere, which is inseparable from the active support of various countries, and is also related to the increasing public attention of blockchain technology
blockchain has a deep origin with bitcoin (in fact, bitcoin is the application of blockchain Technology). Is it a signal released by the central bank? I don't know for the moment. After all, the central bank is now the most credible third party, and the development of digital currency with blockchain technology has the taste of breaking its own path. Bubi blockchain focuses on the innovation of blockchain technology and procts, has a number of core technologies, and has developed its own blockchain service platform. With decentralized trust as the core, we are committed to building an open value circulation network to let digital assets flow freely
who will benefit from the concept of blockchain technology
in which field will blockchain technology be applied first? There is no doubt that blockchain technology will first be applied to the financial system with the highest requirements for security, openness and stability. Let's take a brief inventory of the application scenarios of blockchain in the financial system: issuance and circulation of digital currency, information disclosure and share management of private and public funds, trading system of financial derivatives, transaction records, consumption records, personal lending, small and micro finance, electronic contract, etc. From the perspective of application, Bubi blockchain has been applied to equity, supply chain, points and other fields, and is concting experiments and application tests with exchanges and banks. Bubi blockchain focuses on the innovation of blockchain technology and procts, has a number of core technologies, and has developed its own blockchain service platform. Moreover, many blockchain innovation and entrepreneurship enterprises continue to emerge
for example, the securities exchange market may be the most suitable mole for blockchain in the financial field. Traditional securities trading needs the coordination of banks, securities dealers, exchanges, and central settlement institutions to complete a stock transaction, while blockchain system can independently complete a full set of behaviors: through the digital certificate containing the user's basic information, the user signs the content of the certificate with his own private key, and all the user has to do is press the operation button, And can real-time query whether someone tampered with the content of the certificate. It's not imaginary. In fact, they did. In 2015, NASDAQ Stock Exchange and London Stock Exchange, the world's top four exchanges, have explored the application of blockchain
therefore, software service providers serving the financial system are destined to be the direct beneficiaries of the blockchain concept, unless the application of blockchain technology is a false proposition. Now look at the blockchain technology, it has been initially applied, but the market space is too large for us to measure
chain open standard has been supporting a number of blockchain projects of leading financial companies, which can promote the requirements of open standard through in-depth cooperation with chain as early as 2014. For the first time today, this standard is open to the wider financial sector. The chain open standard is built for specific purposes. It can support large-scale financial applications and meet the strict regulatory, security and privacy requirements of the financial services instry while running the licensed blockchain network<
the chain open standard achieves breakthroughs in the following aspects:
the new consensus model realizes the final completion of the transaction in less than a second, even if the transaction volume is very large
the privacy solution encrypts the blockchain data and allows the relevant counterparties and regulators to read selectively
smart contract framework and virtual machine support simple rule execution and Turing complete program for key value storage
scalable data model can rece the running load for network participants
how to realize blockchain? The current situation of global blockchain development also shows a good prospect of blockchain technology. This trend of comprehensive application will be shown in various fields of various countries.

8. Think too much... Take sha256 for example, the probability that you will collide with the private key is probably equivalent to finding a special atom from all the observable atoms in the universe. It is equivalent to winning millions of grand prizes in a row. This has nothing to do with IQ. This encryption method is barbaric and effective, not high-tech
in the future, blockchain encryption can be said to be cracked. Of course, it's not the current computer system, it's the quantum computer. Once this thing is mass proced, the blockchain will be abandoned.
