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.
It is an indisputable fact that qubu app is suspected of pyramid selling, and qubu's making money is unreliable, so it is not safe
interesting step mode: using blockchain technology to calculate the output of candy based on human movement, participants can proce candy at every step. Candy is very rare and valuable at present. Members feel that candy is valuable, they will buy and sell candy to get cash income, and the platform will charge a handling fee for each transaction. Participants can raise the membership level to ensure more people to participate
Hunan qubu Network Technology Co., Ltd. is suspected of illegal pyramid selling, illegal fund-raising, amount fraud and other illegal acts, and has been put on file for investigation by relevant units. In early August of this year, the official account of the WeChat public warning by the police of Bole was very risky. p>
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
we usually think that the one who maintains the system is the one who manages the database, and other users have no right to participate. Just like the users of a certain treasure can not participate in the specific bookkeeping behavior
but blockchain subverts the tradition and lets every user in the system participate in it
blockchain is like a large total account book. Every user in the system can participate in competitive bookkeeping. In a certain period of time, the system will find the fastest and best users among competitors. The user writes the data changes in this period to a block, just like writing to an account page, and copies this account page to all other users in the system for backup, completing the whole action. In the next period of time, every node in the system has a of the complete ledger
since each block data is linked together through cryptography technology, we call it "blockchain" or "distributed ledger technology"
blockchain, let the whole people participate in bookkeeping. Because there is no specific bookkeeper in the system, any part of the nodes in the system will not affect the operation of the system if they are lost or destroyed. It is safer for all people to keep accounts. The system stipulates that the same number of accounts with the largest number are true accounts, and a small number of accounts that are inconsistent with other users are false accounts. This makes it difficult for a blockchain with enough nodes to be attacked and tampered with. These nodes are distributed in any corner of the Internet. Unless you are God and can control most computers in the world, you cannot tamper with them. Therefore, blockchain is considered to be the most secure way of data management in history. National bookkeeping is more efficient. Because there is no centralized intermediary organization, it can run automatically through pre-set proceres, which can greatly rece costs and improve efficiency, and ensure that the process and content of account records are open and transparent
bitcoin is only an experimental application of blockchain technology in the field of payment. Blockchain can also be used in a broader field, including medical treatment, supply chain, Internet of things, security authentication, social networking and artificial intelligence The economist called blockchain "the trust machine" and believed that it would have a huge and far-reaching impact on global finance and even social structure
to sum up in one sentence, blockchain technology is a way that enables all participants in the system to work together to record and maintain a reliable data log under the environment of multi-party without mutual trust through cryptography technology
bitcoin, blockchain content publishing platform decent and lightcoin all use blockchain technology, and anyone can participate in it in theory.
Ledger is a book with a certain format and several account pages. Based on the accounting documents, it records all economic business in chronological order and classification, which is what we usually call the ledger. Blockchain represents a unique data record format. Blockchain is "block + Chain". The so-called block is the meaning of data block. Each block is connected by a certain mark to form a chain
Super ledger
hyperledger (Chinese name is super ledger, collectively referred to as hyperledger) is an open source project launched by Linux foundation in 2015 to promote blockchain digital technology and transaction verification. The goal of hyperledger is to enable members to work together to build an open platform to meet the needs of various users from different instries, while greatly simplifying the business process. The founding members of hyperedge include IBM, Intel, Cisco and other large companies. By the end of this book, more than 183 organizations and companies have joined hyperedge, and they are growing rapidly
at the beginning of hyperledger project, Linux foundation has received a number of different code bases, including IBM code base (inspired by Ethereum to a certain extent), Dah (bits of proof bitcoin code base) and sockstream code base (an extension of bitcoin code base). In addition, there are digital asset and ripple contributions. With the development of the instry, a single project has been unable to meet the needs of the business, so hyperledger has graally developed from a single project into a project group. At present, hyperledger is not a specific technology, but a set of blockchain technology frameworks. Up to now, the hyperledger project team contains 9 formal projects and more than 50 moles related to these formal projects
