4. What is blockchain technology? What is blockchain
what is blockchain technology? Blockchain is a kind of distributed shared accounting technology. What it needs to do is to enable all parties involved to establish a trust relationship at the technical level. Blockchain can be roughly divided into two levels, one is to do the underlying technology of blockchain; The second is to do the upper application of blockchain, that is, the transformation, optimization or innovative application based on blockchain. What is the core meaning of the blockchain? Our understanding is that the core meaning of the blockchain is to establish data credit between the participants, create unilateral ecology under clear provisions through unilateral confrontation, and jointly guarantee complete opportunities. This is a system, and this kind of construction can end the problems before the blockchain, When data is shared, it is impossible to achieve new sharing. Even if you do orientation, it only gives you an interface. After the blockchain is established, the participants can realize credit sharing
blockchain has been applied in several fields. In the first field of digital assets, in addition to some points and check-in cards we have seen, it also includes various other assets, which have the process of asset digitization
the second area is trade finance, because trade finance is originally a way of multi link participation and multi-party participation, blockchain can greatly improve the efficiency of the middle, making many of the original procts achieve the effect of substitutes
the third area uses equity, which is the company's equity. Like some regional equity trading centers, the purpose is to solve the convenience between equity and trading, and to make a relatively convenient circulation. At present, the multi center blockchain system can indeed improve efficiency and rece costs
Introction to Bubi blockchain
Bubi blockchain is mainly positioned to provide commercial level blockchain infrastructure services, mainly including building a blockchain system and building a supporting system with high scalability on the blockchain system. And the support system above is the application of all walks of life. Bubi focuses more on the underlying technology of the blockchain. In the past three years or so, almost all the energy of the team of more than a dozen people has been devoted to the research and development of the underlying technology. The reason why Bubi blockchain chooses points has something to do with the promotion method of the market. As we all know, blockchain is a very suitable technology for digital asset issuance and trading. Integral is a kind of natural legal and compliant digital asset, which has little impact because of its small amount. So it's a very suitable choice to take points as the first attempt of digital asset issuance. Issuing points based on blockchain can also bring great help to the circulation and exchange of points
blockchain has many entry points in improving the financial system. Which link is the easiest to break through in different links
it is difficult to find a particularly good answer to which link is the easiest to cut in. But generally speaking, clearing and settlement, equity, various digital assets and other links are definitely the scope of application of blockchain. Every field is cutting in at the same time. At present, a realistic entry path is to graally evolve from incremental and peripheral to core components, and it is unlikely to enter the core at the beginning
the so-called peripheral, take clearing and settlement as an example, it is impossible to replace clearing and settlement system immediately at the beginning, but we can take some partial clearing and settlement business as a proof of concept, and graally we can replace and upgrade some large systems. This may be a relatively long process. Now it is difficult to give a time point for blockchain to be applied to clearing and settlement system on a large scale, It depends on the development trend
blockchain does not necessarily have no center. The so-called decentralization is more about establishing a multi center system to better overcome the original decentralized structure of each center
in fact, most of the links in the current financial system have their own centers, and it is almost impossible to share data with trust between each other - although it can connect systems and APIs, it is impossible to share data with trust. Blockchain can help these participants to set up multiple centers, realize joint trust, improve efficiency and rece costs. Therefore, the decentralization of the blockchain is by no means without a center or anti center. It is more multi center or sub center, and the decentralized center is the participants of each business. This is the next step that blockchain will change the financial system the most, and truly build a trusted multi center system
what is blockchain technology? After a certain application analysis, we will go back to the starting point. The definition of blockchain technology will become more and more abundant with the development of application. People will find more mysteries of blockchain technology.

7. 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.
