1. What is blockchain? Blockchain is a technical solution to collectively maintain a reliable database through centralization and distrust in the past. The concept of blockchain first appeared in a paper "bitcoin: a peer-to-peer e-cash system" written by the founder of bitcoin, Nakamoto, in 2008. In short, blockchain is a kind of public accounting technology, which was born to solve the trust cost in our transactions
what is blockchain? Blockchain technology is a way for the whole people to participate in bookkeeping. There is a database behind all the systems. You can think of the database as a big ledger. So it's very important who keeps this account book. At present, whose system will keep accounts, wechat's account book is Tencent's account book, and Taobao's account book is Ali's account book. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there is any data change in a certain period of time, everyone in the system can conct bookkeeping. The system will judge the person who has the fastest and best bookkeeping in this period, write the content of his records into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. This way, we call it blockchain technology
what is blockchain? For example, in our daily online shopping, the money paid after placing an order for the selected goods will first be paid to the third-party payment platform, and the third-party payment platform will only pay the money to the seller's account after the seller delivers the goods to the buyer to confirm the receipt
when a transaction occurs between the buyer and the seller, the system will broadcast the transaction information between them. The person who receives the message will record the transaction after confirming that the message is correct, that is, the person who receives the message has made a data backup for the transaction
just like Zhang Ergou bought an inflatable doll on the Internet, the system would hold a loudspeaker and shout in the village: "Zhang Ergou bought an inflatable doll"“ After hearing the broadcast, the villagers took out a small notebook and wrote it down. Zhang Ergou bought an inflatable doll. Here, the recorded information is like a data backup for this transaction. Back to the current online shopping, if Zhang Ergou's order problems, Alipay system failure can not record this transaction, then Li Goudan's money is not white. On the blockchain, if there is a problem with the order, because in the early stage, the system broadcast everywhere that Zhang Ergou bought an inflatable doll with a loudspeaker, so countless people recorded the transaction information, and there would be no system failure to record the transaction records
what is blockchain? At present, blockchain technology is very popular, especially in the financial sector. Ant finance, LETV finance, Wanda, Ping'an and Minsheng have successively tested blockchain projects, and eurocrowdfunding is in the forefront of using blockchain technology
blockchain is a large-scale and decentralized economic organization mode realized by a group of technologies
bitcoin is a practical embodiment of blockchain technology, which is more accurate than the former
in fact, whether it's blockchain or bitcoin, people are more concerned about the coin itself, which coin makes more money and how to join it
what is blockchain? Blockchain has attracted wide attention because it has changed the original economic organization mode in many fields. For example, in the process of currency issuance and circulation, cryptocurrency makes the core role of the banking system decline, and the organization mode among the central bank, commercial banks and users has changed significantly; In Ethereum erc20 token system, blockchain has completely changed the organization mode among securities issuers, participants at all levels and regulators. Although it brings some problems, it also improves the efficiency of securities issuance and circulation
people are now exploring the application of blockchain in various fields of economy. In essence, they are looking for new ways to use blockchain to adjust or innovate the original economic organization mode of enterprises, instries and regions, and to rece costs and improve revenue. As an economic organization mode, blockchain can be extended downward to its implementation technology, and upward to its impact on social organization and social consciousness, which makes it easier to understand the complex social impact brought by blockchain.

2. 1、 Blockchain will play the role of "recing costs for the real economy". At present, the high cost and low profit of the real economy lead to the lack of capital support for the real economy. In the operating cost, the proportion of management cost and financial cost is not low. Blockchain technology can effectively help enterprises rece the cost of these two parts
secondly, blockchain will play a role of "improving the efficiency of instrial chain collaboration". Enhancing instrial collaboration is an important way to promote manufacturing in China to move towards the middle and high end. However, in many instries, the efficiency of instrial chain collaboration is still not high, especially in the field of international trade
thirdly, blockchain will play a role of "building an honest instrial environment". At present, the construction of China's social credit system is accelerating, but in some cases, the process of building trust among partners is still slow, it is difficult to obtain all kinds of credit information, and it is difficult for small, medium and micro enterprises to obtain credit loans from financial institutions. Through the "transaction on the chain", all aspects can more easily find out the accurate historical credit situation of the counterparties, and establish the cooperation mechanism faster; Banks can also give credit to enterprises more safely based on transaction records, and promote the solution of the problems of "difficult, expensive and slow financing" of small, medium and micro enterprises operating in good faith
in addition, blockchain can make use of smart contracts to avoid default and fraud to a large extent, and can also make efficient and convenient payment scenario applications in combination with blockchain asset wallet. As early as in the blockchain circle, there have been many innovation forums and Instry Summit aiming at the direction of blockchain enabling the real economy, and combining with the local economic instry to carry out landing optimization. For example, the world blockchain conference Macao station intends to make a deep integration with the local economic instry, and use and popularize the blockchain assets with the payment means of magic chain wallet.

3. Hello, cbyea500, the top in APM series< But as an open source flight control system, it can also be programmed by itself
performance is certainly enough for general flight control. In fact, performance is also related to your ability to write algorithms
for details, you can go to the relevant forums and ask< BTW: are you Michael Dou Bi?

4. Open and transparent information and traceability of funds have always been the goals of public welfare and charity. Blockchain can do just that. It can not only track and record all the information, but also ensure that the information is traceable and authentic. As for the successful cases, it seems that there are not many now. After all, it is an emerging technology, and it will certainly get strong support and application in the future.
5. At present, what blockchain can bring to the society is regionalization.
6. Blockchain exploded at the end of 2017. It was influenced by the soaring bitcoin, thunderbolt, storm broadcast, cloud control, Renren blockchain and even Kodak. For a time, the slightly strange technology of "blockchain" seemed to be a magic drug for the stock price to come back to life. Even the prices of counterfeit tokens related to blockchain are like flying
different investors have different views. No matter they think it's a bubble sworn faction, or they regard it as a good candidate for the draught, they do not deny that the block chain is a tool that people can not ignore to change the society. Therefore, it is an important choice to join the blockchain investment platform.

7. Blockchain, a great technology with the birth of bitcoin, can greatly rece transaction costs and improve efficiency in the financial field, which is enough to make Wall Street excited. However, this is only the tip of the iceberg, and its potential application prospects are very wide, which will subvert all aspects of our lives in the future
to put it simply, blockchain is similar to an account book, recording all the transaction information of bitcoin. This ledger is stored on each bitcoin node of the Internet, and each node has a complete backup. The ledger is stored in blocks, and each block contains some transaction records. Each block will record the ID of the previous block, forming a chain structure, which is called blockchain. When you want to initiate a bitcoin transaction, just broadcast the transaction information to the P2P network, record your transaction information as a new block and connect it to the blockchain, and the transaction is completed
to sum up, the biggest feature of blockchain is decentralization. There is no centralized hardware or management organization in the whole network. The rights and obligations of any node are equal, and the damage or loss of any node will not affect the operation of the whole system
the second feature is distrust. There is no need to trust each other in the data exchange between each node in the whole system. The operation rules of the whole system are open and transparent, and all data contents are open. Therefore, within the specified rule range and time range of the system, nodes can not and cannot cheat other nodes
the third feature is to break the information asymmetry. Blockchain's ledger technology will reflect all the information, similar to an open and transparent credit system of the whole society, breaking any asymmetric information in all societies
these three features alone are enough to make blockchain overturn our present life. The financial instry is one of them
Introction to Bubi blockchain
since its establishment, Bubi blockchain has been focusing on the R & D and innovation of blockchain technology and procts, has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as: mathematically verifiable distributed consensus technology, fast large-scale ledger access technology, and so on Multi Chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. 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
for example, our common inter-bank clearing systems, securities settlement institutions and various financial settlement systems are based on this principle, but the difference is that these settlement systems are centralized, that is, there is a central server or central institution to complete the settlement work. If the central institution database is damaged, the whole settlement will go wrong. The settlement system of bitcoin is decentralized and built on the network. We call it P2P network. It is a decentralized settlement database. The destruction of indivial database nodes does not affect the whole bitcoin settlement network at all. Therefore, the distributed data settlement network based on P2P network is a new financial innovation
blockchain technology concept stock? Blockchain is like a database ledger, recording all transaction records. Because of its safety and convenience, this technology has graally attracted the attention of the banking and financial instry. According to the forecast, by 2025, 10% of the relevant information in the global GDP will be saved by blockchain technology. Blockchain technology is facing a blue ocean, and related concept stocks are becoming the wind. In A-share listed companies, it is suggested to focus on the concept leading stocks: Feitian integrity, Yuyin shares. In the future, with the fermentation of speculation, other concept stocks are expected to follow suit
blockchain stock? Blockchain technology concept stock? The part of stock trading is very simple, but the process of clearing and settlement becomes complicated. Blockchain trading can greatly simplify this part of trading
the convenience brought by blockchain is reflected in the stock cash transaction, which mainly reces the time of clearing and settlement process. Specifically, it means to rece or eliminate the wrong transactions, improve the efficiency of the back office, and rece the settlement time.
