However, where are the opportunities for these innocent employees? To put it bluntly, some blockchain entrepreneurs are bent on "empty handed White Wolf", and exploit layer upon layer through "deception". Using asymmetric instry information, blockchain, digital currency and other projects are over packaged, giving people a sense of "Hope". This part of the blockchain entrepreneurs' inherent "bad root", to a certain extent, has led to the instry's "sick" development trend
some blockchain entrepreneurs call for embracing the times, changes and the future, emphasizing the charm of decentralized "fairness". But in reality, it is for self-interest, which hurts the interests of job seekers and other related groups, which is a great injustice in itself
The asymmetry of information is not permanent. Blockchain, digital currency and so on are all areas worthy of attention, but they are not the capital that can be used by some entrepreneurs as unlimited squanders all the time. For the job seekers who want to join them, they should polish their eyes, otherwise they may be surprised if they are not careful2. Blockchain is a shared distributed database technology. Although the wording of a sentence about blockchain in different reports is different, the following four technical features are consensus
1. Decentralized: the left side of Figure 1 describes the centralized characteristics of today's financial system, and the right side describes the emerging decentralized financial system, which has no intermediary, and the rights and obligations of all nodes are equal. Any node that stops working will not affect the overall operation of the system
2. Trustworthiness: all nodes in the system can trade without trust, because the operation of the database and the whole system is open and transparent, and nodes cannot cheat each other within the rules and time range of the system
3. Collective maintenance: the system is maintained by all the nodes with maintenance function, and all the people in the system participate in the maintenance work together
4. Reliable database: every node in the system has the latest complete database , so it is invalid to modify the database of a single node, because the system will automatically compare and think that the same data record that appears most times is true
the blockchains of bitcoin, Ethereum and decent all have these characteristics.

3. For example, I borrow money from you in a village. Normally, if I am afraid that you will not repay the money, I can find an intermediary recognized by everyone, such as the village head as the guarantor, and sign an IOU. In this way, if you default at that time, I can find an intermediary to prove that you really owe me money, But there are two problems: 1. What if the village head finds out that his long lost son colludes with him to cheat you on money? 2. What if the middleman dies on the spot the next day! This is about trust and security. If the method of blockchain is to provide you with the certificate of the whole village (distributed), so that everyone knows about it and the other party can't default on it. Second, even if a small number of people or village heads deny (some nodes commit crimes) that they have lost the IOU or tampered with the content, there will still be others to make the basis
in other words, blockchain solves the problem of trust and security

4. Blockchain is actually an emerging technology. The simplest thing is to play with digital currency. Now I'm doing it on bitmax. This platform is built by the senior quantitative team of Wall Street, which is very good in terms of security and technology.
5. This problem can be solved by Excel standard function, but it's a little boring
to ask a question, there must be a place in your original form where you can identify the currency, right? And before unifying currencies, you need to decide what your base currency is? RMB or USD or something
the information to be prepared is the exchange rate between each currency and the base currency
suppose you have only two currencies, RMB and USD, the base currency is RMB, and the exchange rate is 1usd = 7RMB
suppose the data table format is as follows
col a amount (numerical type)
col B currency
col C our target fields
column A and B are your original data, as long as you write excel function on column C
function = if (B1 = & quot; USD", A1 * 7, A1)
the sorting is nothing special, just the same as before. Excel sorting is not automatic, it is triggered manually, so if you want to sort, go to data - & gt; sort

6. Required, the remaining space is more than 1t, and the storage score of the miner is 10 points; The remaining space is 200g-1t, with 5 points; Less than 200g, 0 point. Therefore, it is recommended to buy 2T hard disk. If you buy 1t, the formatted capacity is less than 1t.
7. First, the POS + pod hybrid consensus mechanism of the exclusive game community greatly improves the efficiency and consistency of the public chain network
Second, community autonomy. All decisions are made by community members. Under the hybrid consensus mechanism, both POS krypton players and pod technology players have higher yield and discourse power, which effectively avoids the impact of centralized computing power and financial resources on the whole game ecology, and thus reces the risk of bifurcation. If a node wants to propose a bifurcation for a certain protocol or standard, all nodes need to participate in the voting. If the pod + POS weighted value of the voting result exceeds 50%, the system defaults to the chain with high weighted value as the effective chain, and all nodes will migrate to the new chain mining at the time agreed in the voting result
thirdly, because game players have requirements for the performance and bandwidth of hardware devices, vs public chain sets the node players involved in accounting into two categories: full node and light node. Players can manually switch between full node and light node. Generally, light node mode is adopted in the process of the game to provide more hardware support for the game, and full node mode is started after the end of the game and ring the hang up period
fourthly, all the transaction rights in the game come from the players. Only after the players are authorized by the exclusive secret key, the game assets can be circulated. At the same time, all transaction data are encrypted by ECC (elliptic encryption algorithm), which is a modern cryptography technology, to ensure the information security of blockchain
fifthly, as a vertical public chain in the game field, vs will first complete the overall solution of decentralized game proction, virtual asset distribution and token economy operation. It includes game engine, developer environment, standard SDK, etc., which reces the difficulty and threshold for game developers to enter blockchain game development from various environments, greatly reces the workload and cost of game development team, and also makes vs public chain highly scalable.

8. What's the purpose of Siku's cooperation with ultrain hyperbrain trust computing plus blockchain? You should say that this is a program connection of computer software. Every computer has a manual when it leaves the factory. Just connect according to the operation manual
