1. Concept analysis of blockchain: it is not only a concept but also a technical system
blockchain is a distributed system, which is constructed by cryptography. Indeed, blockchain is a technical collection of concepts formed by distributed system and cryptography. We should emphasize that it is not only a concept but also a technical system, At the very beginning, blockchain only represented the account structure of the underlying technology of bitcoin. It was a narrow concept. At the beginning, because the development of this technology should be represented by a special term to distinguish it from bitcoin, this word was used to refer to it, and it became a bigger and richer concept and a complete system
when we think back to cloud computing, cloud computing existed before the word cloud computing was put forward. However, once cloud computing was put forward, it developed rapidly along the concept of cloud computing. I think blockchain also has such characteristics, and it will continue to develop. Once it becomes a complete sub Technology system, all the technologies in the sub fields under blockchain will continue to develop, The algorithms in the sub domain will develop in the direction of qualitative change in the way of adding tests. Blockchain is a kind of distributed line or network trust technology. When I studied blockchain technology, there was no blockchain word. We called it distributed computing. On the technical level, end-to-end. From a macro point of view, the blockchain is composed of multiple nodes participated by Dongfang. It is equal. The cooperation of these nodes needs to complete the mutual verification on the blockchain. At this time, there is no need for a central node to do this
macro: distributed equal deployment system, participating nodes cooperate to complete verification and storage
microcosmic: rigorous data structure is packaged and stored in the block, and logically concatenated to form a chain
digital signature and integrity verification ensure the authenticity, real-time and timing of block data
at last, after learning all the technical features, it has achieved the multi fight, informed group and supervision right, because it is transparent, shared and open. All parties of the alliance should participate in the operation of the blockchain system, which is equivalent to a co construction, sharing, sharing and co governance. When constructing the alliance, I have to think of one thing: what I store to the blockchain, which are transparent and which are encrypted. At this time, I need to determine according to your business system. If someone deliberately cheats, he or she will probably find that your data may be tampered or forged with the participation of the public or even the collective alliance, so he or she will consider the cost of doing evil. In this way, the trust cost of the alliance will be greatly reced, and there will be no friction. Outside the alliance, because you believe that you have adopted the blockchain technology, you will have a higher degree of trust in the services or procts provided by the whole alliance, so this is a very good way of virtuous circle
what should you do to build a blockchain system or to bridge business to a blockchain system? There are two steps, very simple. The first step is to construct several key roles in your business logic. Now consider how many roles there may be. There may be many roles, but now consider them as one. These perspectives must be related in business logic. They need to share and map these rules to the blockchain or put them into scripts at the same time. Next, we will talk about data, which data will be put into the blockchain and which will not be put, because the efficiency of the blockchain is security, which is generally simple and key, and only what needs to be built together is considered. On the other hand, even if some data are put into the blockchain, not all things need to be supervised, but may be closed door, and can only be seen after authorization, One is privacy, the other is regulatory compliance
after the first step, the second step is simpler. You need a convenient and reliable blockchain platform. It is an underlying infrastructure, including books, networks, supply and demand algorithms, and accounts. All these things have to exist. After general checking, you can check and send these four blocks according to your business needs. There is a protocol below. The above layer is mapping. This mapping layer is very important. It abstracts your business into many models and logics, and abstracts them into an easy-to-use system. Then you can develop your business logic on the application system, and then develop the business logic based on the blockchain. This is a fast process. In fact, a good blockchain business platform should have its own application tools, as well as monitoring, viewing and auxiliary tools, just like the early days of the database. At the beginning of the database, if it was just data without auxiliary tools, it would be very difficult to run
next, let's share a small case, which is the case of blockchain business points that we just released. There are a lot of views that we have already discussed. We must use points to make it universal, so that consumers can get profits and businesses can rece the burden. Moreover, we can let points flow and guide real secondary consumption. This is of great significance. We have to consider more when we choose commercial competition. Commercial competition itself has a certain financial or monetary attribute. It is a purely low-risk number, because it has the lowest regulatory risk to the extent of compliance and legality. Second, points can quickly accumulate digital assets, accumulate C-end users, test your blockchain platform to a certain extent, and even test your blockchain technology to verify whether your blockchain platform is right. Finally, derived with financial related attributes, for the expansion of financial means behind all laid a good foundation
according to the path of building a blockchain system that we have just seen, the first step is to make decisions. In the blockchain system, it plays two roles: merchant and consumer. Merchants are also divided into two levels, the points they send, the points they receive, and the points they receive are also divided into two levels, the points they transfer out and the points they receive. Rules are non discrimination rules; Data, integral, some data are very interesting. I can write all the people on it, and I can write the effective information on it. There are some consumer behaviors, such as what to buy, coffee or bread. These data are written on it. I will use a simple example to guide you
the second step is to find a platform for blockchain. In our Bubi blockchain, what do we get? We really got a positive feedback. We think it's a very good feedback. First, digital integral represents a variety of data assets, which can be supported on the blockchain. Second, it may have many users, whether real users or laboratory simulation users. It's no problem to support millions of transactions and storage. Third, it really builds a good foundation for us, which lays a good foundation for the exploration in the financial field.

2. digital currency is the proct of currency development to a certain stage. The issuance of digital currency is mainly to make transportation more convenient and also concive to the supervision of the economy.
3. Take it easy! Digital currency play spot is very good! Take it and wait for the take-off! The category of leverage is playing! To a black swan or good, zero minutes!
4. I'm too young to remember the birth of the Internet. When the Internet was booming, I was in high school, a little confused about what happened. At a family party, when my cousin bragged about how much money he made from buying and selling domain names, I thought it was stupid
it's not a reality. Up to now, I still think it's stupid to make money by buying and selling domain names. I know it happens sometimes. It's like a high-risk, low return investment
as a result, the Internet did. Now, 20 years on, domain names are cheap, and search engines make them brand specific Note: the author means that the convenience of search engines makes domain names cheaper and cheaper. Domain names are only related to brands.)
What does this have to do with the value of bitcoin
this is an example of how people's views on value change with the development of technology
at this point, most people see bitcoin as money. The chairman of the US SEC said, "yes, that's how drug gangs use it. Everyone I know thinks so.". It's called "bit coin" for a reason
bitcoin maximalists call it hard currency, critics call it fake money, and veteran players call it cyber currency
W bq89998 push the latest currency from time to time to ensure the minimum 10 times

5. Once you install a hobbit wallet on your computer or mobile phone, it will generate your first hobbit address, and it can generate more addresses whenever you need.
6. Blockchain and distributed ledger technology make digital currency development more reliable
blockchain technology has been questioned by the collapse of the centralized currency exchange, but its potential to solve the trust and centralization problems of the existing information architecture has attracted a lot of attention. Blockchain technology first gained great popularity in the field of bitcoin and digital currency. It uses a single shared ledger to store information. It is no longer to let a single central organization obtain the account book, but to obtain multiple copies of the same distributed account book by different nodes in the peer-to-peer network. Shenzhen yuanzhongrui blockchain technology adopts advanced encryption technology to ensure that any new information in the account book can not be tampered, unless it meets some preset parameters. Moreover, this kind of Ledger has stronger defense against external attacks, such as network attacks, because this decentralized system does not have a single point of failure with high cost of centralized information architecture. At the same time, all trusted nodes can affect any modification of the ledger, provided that they meet the specific preset parameters. These changes will be immediately reflected in the ledger, and all trusted nodes can obtain relevant data to make correct decisions. It can also adjust the design of the distributed ledger, create a hierarchical system within the architecture, and configure appropriate access rights and different levels of authority
blockchain and distributed ledger technology are concive to change the management mode of land registration. At present, the credibility of the real estate market is at the lowest level, which is attributed to the inefficient and opaque property registration system. The system relies on the centralized acquisition of land registration and corresponding property transaction information. Using distributed ledger technology to obtain, manage and modify these information can ensure that the public will not be infringed by land transaction fraud. Similarly, distributed ledger can simplify and integrate cross instry and cross regulatory compliance process, because it contains real-time compliance information needed by government departments, banks, investors and other third parties. By integrating data points of multiple projects and providing feedback on beneficiaries' project participation, we can better track the implementation of social welfare plans
at present, the biggest problems of technology development include: transformation cost of unique data storage system, data reliability verification of network nodes or all levels, privacy and security dimension of decentralized data acquisition, and revision of information technology act. What's important is that blockchain technology will change the way the government interacts with citizens, and this huge change is bound to be resisted by civil servants. These are all possible problems. We should take immediate action to formulate a regulatory framework to guide application development in addition to adopting blockchain technology.

7. Look at the indivial requirements for the accuracy of quantification. What comes out of big data analysis is that the success rate must be higher. Digital currency is still very little to quantify, now it seems that jiuzhuang bcbot is doing quantification. For reference, in a bear market, high-frequency trading will surely be more reliable.
8. If the property is cheated, it is necessary to report to the public security organ in time. The public security organ determines the nature of the case after examination. For those who meet the conditions of filing a case, it is necessary to obtain evidence by means of investigation to solve the case, so as to recover the loss of the victim
legal basis:
166th proceres for the handling of cases by public security organs. The public security organs should give immediate acceptance to citizens for the transfer, reporting, accusation, reporting or criminal suspect's automatic surrender, inquire about the situation, and make notes. After checking correctly, the signers, the complainants, the accusers, the informants, and the automatic surrendered persons will sign their names. Print your finger. When necessary, it shall be recorded or videotaped
Article 174 if, after examination, administrative punishment is not enough for criminal punishment, it shall be dealt with in accordance with the law or transferred to relevant departments
Article 175 after accepting a case, if a public security organ, upon examination, considers that there are facts of a crime that need to be investigated for criminal responsibility and that the case belongs to its own jurisdiction, it shall file the case with the approval of the person in charge of the public security organ at or above the county level; If a person considers that there is no criminal fact, or that the criminal fact is obviously minor and does not need to be investigated for criminal responsibility, or that there are other circumstances in which criminal responsibility is not investigated according to law, the case shall not be filed with the approval of the person in charge of the public security organ at or above the county level
if the public security organ decides not to file a case with a accuser, it shall make a notice of not filing the case and deliver it to the accuser within three days
187th, the public security organs should investigate the criminal cases that have been registered in time, collect and obtain evidence materials of the suspect's guilt or innocence, light offense or heavy crime.

9. Any market can achieve high-frequency trading, but the high-frequency trading cost requires hardware support such as bandwidth server, as well as algorithms for different markets and different periods. Arbitrage trading is really suitable for digital currency, and now the well-known strategy is hummingbird strategy (HMT. One).
10. How to get attack fragments
1. Replenishment (this is nonsense)
2. Store refresh
3. Chance to drop in difficulty 2-15
"nvwushen · assault" is the school uniform of Lei Lei Ya Yi in St. Freya School Park
this "creature" uniform enhances the melee output speed and damage of thunder bud
after a short period of power accumulation, you can launch a series of "void chop", each blow will cause considerable damage, and at the end of the end of the great damage. In the face of floating enemies, the damage and critical hit rate will be further improved
the "nvwushen · assault" in the position of captain can enhance the team's critical hit rate in close combat through "Sakura's border"
after the outbreak of the must kill skill "xuzuo's man", the thunder and lightning sprout clothes enter the apotheosis state, all attacks are strengthened, the blade is huge, and the attack range is expanded. It's the best time to launch a series of killing to give the enemy a fatal blow!
