related books include principles of economics, blockchain: technology driven finance, blockchain Revolution: how bitcoin's underlying technology can change money Business and the world, blockchain technology guide, illustrated blockchain, how blockchain will redefine the world, digital currency: bitcoin data reporting and operation guide, blockchain: from digital currency to credit society, intelligent age, etc. to be honest, blockchain is still a hot resource. It's mainly about judgment (whether it's valuable) and action (to get in early)
recommends a block chain related APP, called golden finance, recommends a public official account, called "Xiao Ke online". The article is rich in materials;
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 />
Specifically, users can share the idle storage space and bandwidth resources of cat disk, and these resources will be output to companies such as content, video, game, blockchain, etc. cat disk company will convert the legal currency and various digital currencies paid by the latter into bitcoin, and users will get the corresponding bitcoin income. This is also the unique mining mode of cat disk
why reward bitcoin
because similar procts on the market reward users with points, diamonds and other rights and interests issued by relevant companies, and most of these rights and interests are of low or no value. In addition, those projects that once seemed to be hot are now almost withered, and the early players may benefit, while the late players will lose all their money
as we know, bitcoin is the anchor currency in the digital currency world. Cat disk directly uses bitcoin to motivate users, and users can pick up the coin to their wallet at any time, and their income can be guaranteed. Moreover, the risk of bitcoin breaking is almost zero, and the user's income will be more lasting and stable
how is the mining income distributed when it comes to distribution, we should first introce the concept of "storage power", which is directly linked to the income of cat disk users. Storage power is an index based on users' shared storage space, bandwidth and online time. The larger the storage space, the faster the bandwidth speed and the longer the online time, the larger the storage power, and vice versa the cat disk gains revenue by sharing storage bandwidth resources, and users can check the revenue through app every day, that is, how much bitcoin they earn. The profit distribution of maopan mining is not random, but through a series of calculations. In short, users' daily income depends on their personal storage capacity, all users' storage capacity and the amount of money issued each day. The calculation formula is as follows: single user's daily income = single user's daily storage capacity / all users' daily storage capacity * Daily currency amount it can be seen that users' daily income is positively correlated with the daily storage capacity index and the daily currency amount, and negatively correlated with all users' daily storage capacity index what is the amount of money issued every day the cat disk integrates the storage and bandwidth resources shared by users, provides storage and bandwidth services to the demander, and converts various digital currencies paid by the other party into bitcoin for distribution to users. How much bitcoin is issued every day depends on the actual business situation, so there is no way to give specific figures for the time being. What we can make clear is that, unlike other mining procts, cat disk does not issue its own currency or restrict the mining of a specific kind or several kinds of currency. Instead, it earns various digital currencies paid by others. These currencies are all market currency. Cat disk converts these currencies into bitcoin and distributes them to users note that all the currencies are negotiable, and the more storage nodes, the more business, the higher the overall mining revenue; For other mining procts, the amount of money that can be mined is limited or issued by the owner. With the passage of time, there will be more and more mining machines, and the mining income will be less and less
then, how to judge whether blockchain technology is reliable depends on two main points
first, there should be a real application scenario. No matter how small the application scenario is, it must be valuable
whether blockchain technology can finally be implemented depends on many complex factors, and one of the key points is the application scenario. To find the corresponding application scenario, we should start from the technical characteristics of blockchain itself. Blockchain technology can provide decentralized, tamper proof, safe and reliable characteristic guarantee without introcing third-party intermediaries
Second, the application of blockchain technology should be able to solve problems, not manufacturing problems
with real application scenarios, it also hit the pain points in the instry, but these are not enough to make blockchain technology truly land in the real economy and realize the integration with the real economy. Because the most critical point depends on whether the blockchain technology is applied to solve the problem
with the application of blockchain technology and the assistance of some Internet of things devices, investors can query the real-time and dynamic data of the project at any time, and can directly monitor the progress of the project in different places even without leaving home
using blockchain technology to solve the original difficult problems, combined with the real application scenarios, the implementation of blockchain technology in the real economy has become a natural thing.
blockchain English Name: blockchain, also known as block chain, is a kind of chain data structure that combines data blocks in chronological order, It is a distributed account book that can not be tampered with and forged by means of cryptography
blockchain is essentially a distributed database, which is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block
2. Working principle
the core potential of blockchain lies in the characteristics of distributed database and how to help transparency, security and efficiency
in the past, institutions used a central database to support transaction processes and calculations. The control of the database is in the hands of its owner, who manages the access and update rights to the database, which limits the transparency and scalability, and makes it difficult for outsiders to ensure that the data records are not manipulated
at the same time, e to technical limitations, distributed database is basically impossible to achieve. But with the development of software, communication and encryption technology, it is possible to build a distributed database across organizations. Blockchain has graally emerged
3. Core idea
the basic idea of blockchain is to establish a network-based public ledger (data block), each block contains the information of a network transaction. All the participating users in the network work together to keep accounts and check accounts. All the data are open and transparent, and can be used to verify the effectiveness of the information. In this way, the authenticity and non tamperability of information can be guaranteed at the technical level without the central server as the trust intermediary.
