4. Blockchain: from digital currency to credit society
5. What is bitcoin
so what is bitcoin? First of all, remember that bitcoin is an electronic currency based on P2P and cryptography. Peer to peer transmission (P2P) means a decentralized payment system. Unlike most currencies, bitcoin does not rely on a specific currency institution. It is generated by a large number of calculations based on a specific algorithm. Cryptography is used to ensure the security of all aspects of money circulation
with this concept in mind, we can understand the wonders of bitcoin through an application scenario:
in a second grade class of primary school, in order to encourage students to study hard, Mr. Wang ranked after each exam, adding three little red flowers to the top 10, and adding one little red flower to 10-20, The last five minus a little red flower each time... The change of little red flower is recorded by the monitor Yang Yang. The number of little red flowers can be exchanged for animation books or beautiful stationery in the class bookshelf
in fact, in real life, the responsibility of the bank is the same as that of the monitor Yang Yang - they are all bookkeeping (except that Yang Yang records little red flowers and the bank records money). Pay wages, the bank to your account plus 5000 yuan; Buy a bottle of shampoo minus 20 yuan; One year deposit plus interest of 100 yuan; Transfer is to subtract 1000 from your account and add 1000 to the other's account...
the biggest difference between the bank and the monitor Yang Yang is that Yang Yang serves you for free, but the bank asks us to collect money, card fee, annual fee, transfer fee... Just look at the number of high-rise buildings and employees in the bank, you can know how much money the bank has collected from us
however, the system of relying on the records of the monitor Yang Yang is not very solid (the bank relies on government intervention), because some students began to make their own little Safflower in order to change more books and stationery. The growth of the number of little safflower has exceeded the purchase speed of bookshelves, and eventually students no longer believe in little safflower
the teacher has come up with another way, instead of using the little Safflower in the form of material object, he has to keep accounts! Each student has his own "little safflower account book", and set up "little safflower account book" in the monitor. When the transaction occurs, students in the monitor's witness, fill in their own books. If a student wants to modify his account book secretly, but he can't match the monitor's general ledger, he will find the problem
such a system solved the problem of students making their own little red flowers. However, it didn't last long, and the monetary system soon collapsed, because one day, a student found that the girls at the same table with the monitor always had endless little red flowers. As for why he wanted to (the disadvantage of central institutions issuing currency)
in view of this situation, teachers once again play their wisdom, as follows:
1) no longer set up a general ledger
2) all the students in the class maintain an account book together. No matter whether there is any change, the account book will be updated every 10 minutes, and all the students will be informed after the update
3) every day after school, all the students who want to keep accounts calculate today's transactions together, and the first student who calculates correctly gets a reward
4) after daily calculation, a transaction can only be recognized if it is consistent with the records of most students
in this way, it is very difficult for someone to modify the account book secretly. He has to check with the account book of the whole class. Only the vast majority (more than half) of the students' accounts can be matched with you (maybe some students have a wrong account), can this transaction be recognized. At the same time, it also aroused the enthusiasm of the students to calculate the accounts, because the students who calculated the first time were rewarded. And this mode is the bitcoin system in which bitcoin exists
in this scenario:
① the little red flower on the ledger is a kind of digital currency, equivalent to bitcoin
② the network composed of the whole class is a P2P network. Each student is equivalent to a node
③ the system composed of students and ledger is like a regional chain
④ there is no "little red flower general ledger" stored in the monitor, which is decentralization
⑤ the students who are calculated first will be rewarded, which is mining< There is a classmate who uses a calculator, which is faster than others. This calculator is equivalent to a miner< If students don't write their own names on their account books, but use their own symbols, this is the embodiment of anonymity
at first, bitcoin was of little value, only his inventor, Nakamoto Tsung, was willing to mine. After Nakamoto quietly g more than 1 million bitcoins, some people finally began to join the mining team. Later, some physical stores and websites began to accept bitcoin payment. With the increasing demand for bitcoin, bitcoin became more and more valuable.
so what is bitcoin? First of all, remember that bitcoin is an electronic currency based on P2P and cryptography. Peer to peer transmission (P2P) means a decentralized payment system.

6. Hashton business school is good. It focuses on blockchain ecation and training. Through group learning and taking the exam, it has obtained the certificate of blockchain consultant.
7. Considering all aspects, if you are not familiar with blockchain, don't follow suit. What you often say is very beautiful, the trap is also unfathomable, and you will fall miserably in the end! That's a good thing. I don't want to make a fortune with my own muffled voice, but I also need so much news and war to publicize and agitate
a person who is engaged in a major he likes and depends on his skills can be practical, stable and confident at any time, which can last for a long time
it's hard to be sober and unmoved in the face of temptation, but we should also stick to it. From user: Mr. Bu
thank you for your invitation
blockchain is a new instry rising in recent one or two years. The heat is pretty good. Some hot money has gone in. It's just that there are still many differences in the understanding of policy disputes, the practicability of blockchain technology, and the realization of implementation
I personally take a cautious attitude
as for the skill training of blockchain, I haven't seen any information of professional institutions carrying out such training and ecation. Even if there is, it is recommended to have a thorough understanding
if you want to research, I suggest that you consider securities funds, securities fund analysts, sponsors (the securities bull's mess)
I hope it can help you. User: Mr. Xing

8. The certificate number can be found on the official website. It won't be fake, will it
9. 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.
10.
The mechanism of mineral refresh in the original God is 72 hours (3 days) refresh. Four people form a team to dig the mine, and rotate every day. They can also dig all the mines of four people at one time, once every 4 days. But they still have to go to the blacksmith's place to make iron every day. Crystal ore is refreshed every 3 days, white iron ore is refreshed every 2 days, and iron ore is refreshed every 1 day
for the mining mechanism, there is no upper limit (or the upper limit is very high) for mining every day after the public beta, but the weapon experience materials obtained by forging in different ways at the blacksmith every day have a common upper limit of 300000 (equivalent to 120 crystal minerals, except weapons), which means that iron ore, white iron ore and crystal ore share the upper limit
extended data:
it is suggested that three people should take turns to dig one person's world's mine a day; Suppose we dig a on Monday; Dig B on Tuesday; Dig C on Wednesday; Thursday dig a; By analogy, there will be mines every day. Similarly, Xiaobian suggests that the resources with a brush of 48 hours should be mined once every three days
in the game of the original God, the more advanced the ore, the longer the refresh time. For example, for low-grade ore such as iron ore, the refresh rule is once a day; Pyrite, yeposhi and perlite are refreshed every two days, while crystal ores are refreshed every three days
