Blockchain will subvert content distribution logic

1. First, the characteristics of decentralization
as the name suggests, a blockchain does not need a centralized server, and all information is stored on each node in the chain in a distributed form. Even if a node is damaged or tampered, the operation of the whole blockchain will not be affected, and the data will not be disordered
Second, consensus mechanism
consensus mechanism plays an important role in the trustworthiness of data on blockchain. Due to the decentralized architecture, any two nodes in the chain do not need to trust each other's identity to establish a connection, and there is no need to trust each other for data exchange. Since all nodes in the network can act as "supervisors", there is no need to worry about fraud. When a transaction is completed, all nodes on the blockchain will synchronize this information, so the consensus mechanism is based on the distributed architecture to ensure the data can not be tampered with
Third, smart contract
before we talk about blockchain + smart contract, let's first clarify the meaning of smart contract: a set of commitments defined in digital form, on which contract participants can implement these commitments. Generally speaking, it is a smart contract. In a computer system, when certain conditions are met, the contract can be executed automatically.

2. At present, blockchain technology is mainly applied in smart contract, identity authentication and asset transaction

in addition to solving the security problem, blockchain technology can also change the following areas:

1. In the future, music right distribution is likely to enter the stage of blockchain, removing the intermediate link, so that musicians can get more direct income. In the past, record companies or the Internet were required to increase user stickiness. There were a lot of fees in the middle of promotion or song playing, but not many were really given to the authors, because the original right was still in the hands of several major record companies

2. Writing right is the same. For example, you may have to find a publisher before. This right can't be sold many times, and the money given to the author is also very small. With blockchain technology, all users need to pay the right fee to the author, not limited to a single publisher. Previously, Mr. Li Xiaolai did the press one project, which is mainly aimed at right distribution

3. The Internet of things and blockchain technology will combine to proce the blockchain Internet of things (Biot). Blockchain Internet of things can greatly rece the risk of hacker attacks. With the help of blockchain Internet of things, it may be as convenient as mobile phones to obtain warehouse sensor data

Kevin Kelly's book out of control has become the wind vane of the development of the Internet. In his later book necessity, he also mentioned that "technology has a preference in nature, which makes it move in a certain direction. On the premise that other conditions are the same, the physical and mathematical principles that determine the development of science and technology will favor certain specific behaviors

the development of blockchain technology is an "inevitable" trend, and bitcoin and some valuable digital currencies are only proced because of one of the needs. Today's blockchain is like the Internet in 1994. The development of the times will screen out the best technology and procts. It's just a matter of time

now there are too many "pseudo blockchain" projects focusing on blockchain, because too many people blindly invest in them without understanding. I want to make a fortune in this market. Those people are aiming at leeks that enter the coin circle without learning anything. They casually make small packages on the open public chain, issue a coin, hold a roadshow and want to circle a group of people to come in. They want to run after they circle money. In fact, they have no actual technical content and can't solve any practical problems.

3. The subversive characteristics of blockchain lie in the following four aspects: first, transparency. The data record of the blockchain system is transparent to the nodes of the whole network, and the update operation of the data record is also transparent to the nodes of the whole network, which is the basis of the trustworthiness of the blockchain system. Because the blockchain system uses open source programs, open rules and high participation, the data records and operation rules of the blockchain can be reviewed and traced by the nodes of the whole network, with high transparency< Second, openness. The blockchain system is open. In addition to the fact that the private information of the parties directly related to the data is always encrypted, the data of the blockchain is open to all (except the blockchain system with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through the open interface, so the information of the whole system is highly transparent< Third, information can not be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for private blockchain systems with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high
Fourth, decentralization. Decentralization is the most basic feature of the blockchain, which means that the blockchain no longer depends on the central processing node and realizes the distributed recording, storage and updating of data. In the traditional centralized network, attacking a central node can destroy the whole system, while in a decentralized blockchain network, attacking a single node cannot control or destroy the whole network. More than 5% of the nodes in the master network are just the beginning of gaining control. 2019 is the first year for the commercial application of blockchain technology, and the stimulation of favorable policies will make the development of blockchain technology more stable
with the application of blockchain technology graally penetrating into many fields such as digital finance and Internet, we have a clearer understanding of the value of blockchain
blockchain has formed a situation of global competition, and all countries are seizing the development opportunities, let alone China; Therefore, there is no doubt that blockchain has become a national strategy.

4. In its 2016 investment theme report, Citigroup said: blockchain technology will not lead to financial disintermediation (i.e. financial decentralization), but blockchain technology will greatly benefit the financial instry, such as improving the level of transaction automation and recing operating costs. Transaction checker will continue to check transactions and update classified books, and financial assets can be transferred immediately, So as to improve the settlement efficiency; The transaction information in the blockchain can also be made public to all participants in the network, bringing greater transparency and security to the transaction; Ensure seamless and automated transactions of electronic assets, and bring innovation to the fields of secure settlement, payment, identity management, accounting insurance and Internet of things; Rece the operating costs of the syndicate loan
however, while affirming the potential development of this technology, the report also points out that financial institutions have excessive pursuit of this technology, and blockchain technology is still facing practical challenges, such as the need to establish legal tender for blockchain
with the combination of real assets of digital currency, coin Ying China has launched a new mode of blockchain + crowdfunding, providing players with a more flexible exit mechanism.

5. Since the origin of money, the development of trade between people and countries has become more smooth and convenient. The exchange of trade proces a large amount of transaction information, which is initially recorded by some special systems, such as the government system and the banking system, so it is often confidential and not open to the public. Therefore, when we trade with unfamiliar counterparties, we need reliable third parties or intermediaries who have the above information records to help us audit the authenticity of the transaction, such as the government, banks, accountants and notaries. These are called "reliable third parties"
the emergence of bitcoin makes the status of "trusted third party" in danger. Bitcoin maintains a public account book through computer networking, which is completely open and not controlled by any organization. To be more precise, it is a large digital ledger that is publicly accessible and maintained by the whole distributed network, which we call "blockchain"
in the blockchain, all transactions are recorded, including the date, time, trading partner and number of transactions. Each node in the network has a complete of the blockchain ledger, which is equivalent to that each node has a of the ledger. Blockchain uses advanced and complex mathematical principles to allow all users in the system to participate in bookkeeping competitively. In a certain period of time, the fastest and best user records will be selected and recorded in the big ledger
nationwide bookkeeping makes the system have no specific independent third-party bookkeeper, the records on any node of the system are lost, and the other nodes have a full set of books, so that the information transmission and transaction conclusion will not be affected. If someone tries to make fraulent transactions, its node information will not be able to reach a consensus with the network, because its account book content is inconsistent with most people's account books, so it will not be recognized by the public, unless he can tamper with the account book records of more than 51% nodes. Obviously, this is difficult to achieve, because no one can control the accounting computers distributed on nodes all over the world at the same time. Therefore, blockchain will not lead to false transactions
through the blockchain, every transaction is open, and thousands of nodes anonymously identify the date x, time y, quantity n, etc. of the transaction, which is just like justifying all transactions as a notary. In this way, we share the same data source, which is open, transparent and reliable. This is the reason why we trust blockchain and the essential attribute of blockchain technology
in short, blockchain can subvert the existing world. Ethereum and decent are the most typical examples. However, at present, they only stay in theory.

6. A federal judge yesterday ruled that the IRS has access to user information on coinbase, the bitcoin and Ethernet exchange. The judgment came into force on November 30, Jacqueline; Scott & Chen 8226; Judge Jacqueline Scott Corley decided to approve the IRS petition, allowing it to investigate any possible tax avoidance in the United States
coinbase said it was aware of the existence of the judgment and would make a formal statement shortly

and the US government is celebrating this victory. Director of the IRS, John J; John Koskinen said:

like other properties, virtual currency transactions are taxable‘ The purpose of John Doe's summons is to ensure that citizens in emerging economies can abide by tax laws and fulfill their responsibilities

the coinbase user information that IRS applied to view was from December 31, 2013 to December 31, 2015. Coinbase said it would try its best to protect users' privacy when it first received the subpoena

as we all know, the attitudes and regulatory policies of countries around the world towards digital currencies such as bitcoin are not the same, and the tax policies of different countries are also different
on October 22, 2015, the European Court of Justice ruled that transactions in bitcoin and other virtual currencies would be exempt from value added tax (VAT). This decision is a major victory for the bitcoin trading community

generally, Japanese people need to pay 8% consumption tax to buy bitcoin on the digital currency exchange. In October this year, it was reported that the Japanese government planned to cancel the consumption tax generated by the purchase of virtual currencies such as bitcoin next spring

since 2015, the IRS has regarded bitcoin and other digital currencies as taxable assets. Recently, the IRS inspector general has been responsible for the Department's gaps in digital currency taxation. The American Institute of Certified Public Accountants (AICPA) has raised similar questions.

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
