What is IBM blockchain technology
what is centralization
the so-called centralization means "ownership" or ownership by the company. For example, Tencent's q-coin, which is issued by Tencent, is a kind of centralized electronic currency, including the total amount and the issuing method, is supervised and controlled by Tencent. You can use it, trade and go shopping, but you always have to operate in the framework of Tencent, and the final right of interpretation belongs to Tencent
the issuing mode of bitcoin is preset by the program and encryption algorithm, and runs on multiple nodes all over the world. No one or organization can modify it (everyone has his own account book, so it is impossible for one person to control everyone's account book at the same time. If there is such a technology, why should it be so complicated, If you want to blackmail money into your account, you will be the richest man in the world. There is no one left, And it is not controlled by any single person or organization
take an example: for example, Lao Zhang borrows 100 yuan from Lao Li, but Lao Li is afraid that he will default, so he asks the village head to do notarization and write down the account. This is called centralization. But if you don't find the village head, you can use the loudspeaker to shout in the village: "I Lao Li lent Lao Zhang 100 yuan! Please put it in the account book. "We all put this account in our own account book. This is called decentralization
anyone who transfers money between them will release information through loudspeakers. After receiving the information, everyone will record the transaction in their own account book. With distributed ledgers, it doesn't matter if Lao Zhang or Lao Li's ledgers are lost, because Lao Zhao, Lao Ma, Lao Wang and other families have ledgers
the main advantages of blockchain are that it does not need intermediary participation, the whole process is open and transparent, and the cost is low, and the data security is high
at present, blockchain is in a stage where everyone talks about blockchain, but can't perceive its actual technical charm. Since 2017, it has graally come into our sight, and we have graally realized that bitcoin is more fierce than real estate speculation (the price of mining machinery has skyrocketed! The news is on the screen But I still don't know
so, in which fields can blockchain be applied, what kind of changes will it bring to our future life
the core key: everyone has an account book, everyone has an account book, and the information recorded in each person's account book is consistent and synchronous, and the information is completely transparent. If it is fake, it will be the public enemy of the whole people, which greatly increases the cost of data fraud
core key 2: decentralization, which does not need a central system to manage data, prevents some people from changing data and damages the interests of the majority of people
Application:
1. Account security and privacy protection: currency transfer, exchange, payment system. Blockchain can help prevent data manipulation and fraud, prevent distributed denial of service attacks (DDoS), and effectively protect users' network privacy. Key words: anti counterfeiting, anti-counterfeiting, loan payment
2. Copyright regulation and interest disputes: for example, when a song is downloaded, from the author to the procer and then to the singer, they can get payment in real time through the blockchain, without having to wait for a long time like the traditional way, or even get no reward e to right disputes. Instead of waiting for publishers to provide royalty checks, creators can freely control the process from publishing to payment through blockchain application. Key words: real time receipt, no property dispute
3. Internet of things + artificial intelligence: the intelligent devices in the Internet of things based on the blockchain will be used to monitor the real-time situation of urban infrastructure such as bridges, roads, power grids, etc. the blockchain can connect these intelligent devices together for unified management to help them monitor more efficiently. This will help people better understand how to build a smart city in the future. Key words: unified monitoring, intelligent city
4: proof of existence: in life, once you are asked to prove that you are you, that your mother is your mother, that you have never been married, that the house belongs to you, and so on, things seem very simple. Once it falls on you, it is a great trouble. The application of blockchain technology can perfectly solve the above embarrassment. At that time, all the information that belongs to you will be recorded accurately and can not be tampered with. No one has the right to change it. When the technology develops to a certain stage, birth certificate and marriage certificate may be recorded on the blockchain. Keywords: no keywords
in addition to the application scenarios mentioned above, blockchain technology can also be applied to e-commerce, data storage, logistics and other fields. As long as we grasp the characteristics of blockchain technology, it will become easy to understand.
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 the information of a bitcoin network transaction, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
some areas where blockchain can be used can be as follows:
& ᦇ 9642; Smart contract; Securities trading; E-commerce; Internet of things; Social communication; File storage; Proof of existence; Authentication
&9642; Equity crowdfunding
we can compare the development of blockchain with the development of the Internet itself. In the future, something called finance Internet will be formed on the Internet. This thing is based on blockchain, and its precursor is bitcoin, that is, traditional finance starts from private chain and instry chain (LAN), bitcoin series starts from public chain (WAN), They all express the same concept - digital asset, and finally converge to an intermediate equilibrium point
The evolution mode ofblockchain is as follows:
& 9642; Blockchain 1.0 digital currency; Blockchain 2.0 digital assets and smart contracts; Blockchain 3.0: implementation of distributed applications in various instries
A: the main application fields of blockchain technology are finance, Internet of things and logistics, public service, digital right, insurance and public welfare
First, in the field of finance,
blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields
Second, the Internet of things and logisticsblockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management
Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs Sixth, the data stored on the public welfare fieldblockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision
the principle of blockchain can be more widely used in other innovative fields. For example, blockchain is expected to establish a points exchange and transaction system, which can be used for the exchange and transaction of various points, such as telecom telephone fee points, aviation mileage points, hotel accommodation points, etc. In the field of Internet of things, IBM has cooperated with Kouvola innovation in Finland to establish a trusted cargo view of the whole process of logistics in the technology of blockchain and Watson Internet of things
in fact, in the next few years, the Internet of things will become one of the most exciting and largest application fields of blockchain. Blockchain solves the trust problem and financial transactions between massive devices and nodes in the Internet of things. The Internet of things based on blockchain and e-money can enable smart appliances to automatically complete financial transactions such as paying electricity bills, while IBM Watson cognitive technology can automatically recommend a more reasonable level of electricity consumption by learning historical data, which can form a real smart grid from the perspective of the whole society
in May 2016, two Chinese blockchain enterprises announced to join the hyperledger super ledger project led by IBM and Linux foundation. Also in May, Ping An Insurance Group announced to join the international R3 alliance to jointly develop innovative business applications based on distributed shared ledger technology with other financial institutions
now, blockchain is not only as simple as having influence on Internet technology, but also to create a new decentralized next-generation business model, which is the real significance of the blockchain revolution< br />
blockchain is a brand new proction relationship. The means of proction and the way of distribution are essentially a redistribution of interests. From this perspective, it is far more than a simple technology. In essence, blockchain can integrate procers, consumers, investors and other participants. As a result, friction is subtracted from the value in the process of circulation. If friction is subtracted from the value in the process of circulation, its liquidity will become very, very large, and the new proction relations will promote the progress of proctivity from this angle
the surging wave of science and technology in the world is accelerating the development of blockchain technology, and more favorable policy environment is promoting the implementation of blockchain instry. Breaking through the technical threshold is the most important innovation of development, and IBM capital ushered in the era of artificial intelligence digital currency trading

IBM capital has become a leading company in the U.S. financial services instry, providing unique procts in securities brokerage, wealth management, venture capital, private equity, trust and other fields, as well as investment initiation loans to provide financing services for customers
the best value carrier is Tongzheng, the original intention of returning to the Internet is decentralization, and blockchain technology is the key to Internet decentralization. The change brought by blockchain technology to the instry is the change of proction relations, and the payoff is achieved through the decentralized system
blockchain brings about a change in proction relations. The combination of blockchain and AI, or mutual promotion, brings about a very benign change of social economy and community ecology. In the field of blockchain, IBM capital is increasing investment in a series of projects and technological innovation, and is striving to promote intelligent trading and innovative trading technology in this field.

All transaction orders are executed on the world's largest Lmax platform regulated by FCA in the UK. Bancor, the world's famous mobile trading system, provides technical support for blockchain transaction
the future of currency is digital currency. In the new era of encrypted asset trading, IBM capital deeply insight and explore the prospect and practice of technological innovation in the new financial field, strive to explore the digital password behind the blockchain technology, witness the subversive technological change and instry upgrading of the financial instry in the future, let's work together to change the world and create a better future.
1. Technical language
Python and go are two technical languages mentioned by many companies. Learning needs to be a priority. Moreover, these two languages have great application in the technical direction outside the blockchain. For example, go is used in the background construction of large concurrent systems, and Python is used in the construction of artificial intelligence systems. So learning these two languages is a priority
2. Technical framework
master one or more of bitcoin, Eth and hyperledger. Needless to say, BTC is written in C + +. A large number of currency projects, such as lightcoin, dash, Monroe, zcash, use bitcoin technology for secondary development
eth is the representative of blockchain 2.0, which can build a variety of application classes DAPP on eth network. Now a large number of application blockchain projects are developed using eth platform
hyperledger fabric is a blockchain development platform pushed by IBM, which is mainly used for the development of alliance chain, and is the most popular alliance chain development platform at present
3, algorithm
pow (proof of work), POS (proof of rights and interests algorithm), pbft (Byzantine fault-tolerant algorithm) are all important components of cryptography in blockchain. A full understanding of these algorithms will help you to have a better understanding of cryptography when you participate in the underlying development of blockchain projects
extended data:
blockchain technology is a kind of Distributed Accounting Technology, which is characterized by decentralization, openness and transparency, so that everyone can participate in the establishment of the database, and each established data can not be tampered with, and everyone participates, The problem of trust between strangers is solved
blockchain technology has emerged. It is an accounting technology with the participation of the whole people. The transaction information and data between AB and ab are published to the public and can not be tampered with. As we all know, there is no need for any authoritative Third Party C here. In other words, everyone in the system plays the role of C, which is also called decentralization
