Blockchain account

1. Many blockchains are registered in Singapore, and most of them are registered non-profit foundations. How can they be registered legally? In fact, registration is legal and in line with the local laws and regulations of Singapore, so there is no such thing as illegality
when we say whether it's legal or not, we mainly talk about blockchain coin issuing, not registration. Officially, because of concerns about legal compliance, most blockchain issuers will submit legal opinions, especially the non securitization proof of token
at present, many enterprises set up Foundation Ltd. (Foundation) in Singapore because ICO is a new financing mode of digital currency, such as bitcoin, which is based on blockchain by issuing digital encryption token
What are the conditions for registering Singapore Foundation:
1. Provide the name of Singapore foundation ending with Foundation Ltd
2. Provide a member's ID card and passport
3. Provide a witness's ID card
4. Business scope of Singapore company
5. Members and witnesses hold ID card or passport photo

2. Blockchain itself is decentralized, either for indivials or teams. It doesn't have to be a company. If your project needs to be engaged in offline business, you need to register a company. However, if you are engaged in pure blockchain network, there is no need to set up a company. For example, the well-known hummingbird strategy Arbitrage (HMT. One) is carried out between different exchanges.

3.

The strict definition of blockchain refers to the distributed database technology that multiple nodes in peer-to-peer network jointly maintain a continuously growing list ledger constructed by time stamp and orderly record data blocks through consensus mechanism based on cryptography technology. This technical solution allows any number of nodes in the participating system to calculate and record all the information exchange data in the system in a period of time to a data block through cryptography algorithm, and generate the fingerprint of the data block for linking the next data block and checking. All participating nodes in the system jointly determine whether the record is true

blockchain is a technical solution similar to NoSQL (non relational database). It is not a specific technology, and can be implemented through many programming languages and architectures. There are many ways to realize blockchain, including pow (proof of work), POS (proof of stake), dpos (delegate proof of stake), etc

the concept of blockchain was first proposed in the paper "bitcoin: a peer-to-peer electronic cash system" by indivials (or groups) who call themselves Satoshi Nakamoto. Therefore, bitcoin can be regarded as the first application of blockchain in the field of financial payment

< H2 > [popular explanation]

no matter how big the system or how small the website is, there is a database behind it. So who will maintain this database? In general, who is responsible for the operation of the network or system, then who is responsible for the maintenance. If it is wechat database, it must be maintained by Tencent team, and Taobao database is maintained by Alibaba team. We must think that this way is natural, but blockchain technology is not

if we think of the database as a book, for example, Alipay is a typical account book. Any change of data is bookkeeping. We can think of database maintenance as a very simple way of accounting. In the world of blockchain, everyone in the blockchain system has the opportunity to participate in bookkeeping. The system will select the fastest and best bookkeeper in a period of time, maybe within ten seconds or ten minutes. The bookkeeper will record the changes of the database and the account book in a block. We can think of this block as a page. After the system confirms that the records are correct, the system will record the changes of the database and the account book in a block, It will link the fingerprint of the past account book to this paper, and then send this paper to everyone else in the whole system. Then, over and over again, the system will look for the next person with fast and good bookkeeping, and everyone else in the system will get a of the whole ledger. This means that everyone as like as two peas in the system is called Blockchain. It is also called distributed account technology. P>

as like as two peas (computer) have identical accounting books, and everyone has the same rights, they will not collapse e to the loss of contact or downtime of a single person. As like as two peas, the data is transparent and everyone can see what changes are in every account. Its very interesting feature is that the data can't be tampered with. Because the system will automatically compare, it will think that the same number of books with the largest number are real books, and a small number of books with different numbers are false books. In this case, it's meaningless for anyone to tamper with his own account book, because unless you can tamper with most nodes in the whole system. If there are only five or ten nodes in the whole system, it may be easy to do so. However, if there are tens of thousands or even hundreds of thousands of nodes and they are distributed in any corner of the Internet, unless someone can control most computers in the world, it is unlikely to tamper with such a large block chain

< H2 > [elements]

combined with the definition of blockchain, we think that we must have the following four elements to be called public blockchain technology. If we only have the first three elements, we will consider it as private blockchain Technology (private chain)

1, peer-to-peer network (power equivalence, physical point-to-point connection)

2, verifiable data structure (verifiable PKC system, non tampering database)

3, distributed consensus mechanism (Solving Byzantine general problem, solving double payment)

4 Game design of Nash equilibrium (cooperation is the strategy of evolutionary stability)

< H2 > [Characteristics]

combined with the definition of blockchain, blockchain will realize four main characteristics: decentralized, trustless, collective maintenance and reliable database. And the other two will be derived from the four characteristics  Features: open source  Privacy. If a system does not have these characteristics, it can not be regarded as an application based on blockchain technology

Decentralized: there is no centralized hardware or management organization in the whole network. The rights and obligations of any node are equal, and the damage or loss of any node will not affect the operation of the whole system. Therefore, it can also be considered that the blockchain system has excellent robustness

trustworthiness: there is no need to trust each other when participating in the data exchange between each node in the whole system. The operation rules of the whole system are open and transparent, and all data contents are also open. Therefore, within the specified rule range and time range of the system, nodes cannot and cannot cheat other nodes

collective maintenance: the data blocks in the system are maintained by all the nodes with maintenance function in the whole system, and these nodes with maintenance function can be participated by anyone

reliable database: the whole system will enable each participating node to obtain a of the complete database in the form of sub databases. Unless more than 51% of the nodes in the whole system can be controlled at the same time, the modification of the database on a single node is invalid, and the data content on other nodes cannot be affected. Therefore, the more nodes and computing power in the system, the higher the data security in the system

Open Source: since the operation rules of the whole system must be open and transparent, the whole system must be open source for the program

Privacy Protection: since there is no need to trust each other between nodes, there is no need to disclose the identity between nodes, and the privacy of each participating node in the system is protected

4. Blockchain mainly solves the trust and security problems of transactions, so it proposes four technological innovations to solve this problem:
(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts

You can participate in it with small funds. Bijing is the next generation Internet outlet. The following is my investment experience in the past year. I hope it can help you

taking advantage of the holiday to relax physically and mentally, I took stock of the pits I stepped on and sorted out the gains and losses. My experience is as follows

1. In the early days, I believed too much in the big V of the coin circle and bought some coins from their platform. Now it is close to zero. I feel that I am really naive to believe their lies. In the face of the temptation of huge wealth, people can hardly stand the test. Of course, they can't get beyond it. However, if they don't accept what they say and do, they will lose their moral bottom line. They make a lot of money, leaving me shivering on the top of the mountain

two, the official account of the currency circle and all kinds of media, the judgement of the market trend is almost the same as that of the throwing dice. Of course, this is not to say that the media are totally irresponsible, or that they are not competent at all. In fact, some media are more reluctant to feather their feathers and do their best to analyze projects for fans and judge the trend. But don't forget, in essence, the market is unpredictable, otherwise it will not be called the market. Makers and leeks are always playing cat and mouse games. The prediction of the media will often provide the smart makers with reverse action guide. When most media are optimistic about the market, it is also the time for the makers to raise their sickle; When the media generally think that the market needs further exploration, the makers may be stealing Yu Jiancang, which is not difficult to understand, because the media acts as the opinion leaders of leeks

Third, the current market mainly shows the characteristics of investment gold plate, with speculation as the main factor, and the real block chain value investment has not been reflected. The performance is that almost all counterfeit currencies are linked with the rise and fall of bitcoin. Why bitcoin? Because there is no other standard to rely on. If there is no killer application, this linkage effect is difficult to break, and there will not be a real bull market in the currency market. The killer applications mentioned here are not like Ethereum, such as issuing currency and being an underlying public chain, but have real landing application scenarios, which can link the virtual digital assets on the chain to the supply and demand of real scenes. At the same time, DAPP should have a good user experience and be accepted by the public outside the coin circle. In this way, digital currency will have real support, and the development of blockchain will usher in the spring, otherwise it will be speculation

Fourthly, we often set out from the historical phenomenon to form the expectation of the future. In 2017, some counterfeit coins went out of the market 100 times or even higher, so I always felt that the counterfeit coins in my hand had gone up three or five times after I bought them, which was not enjoyable and not in place. As a result, I didn't sell them in time, so it was rotten in my hand. To analyze, this is not the time. At that time, there were less projects and more funds. At this time, there were more projects and less funds. The situation is just the opposite. Ignorance and greed are very dangerous. Since 2018, with the big V's profits leaving the market, the funds in the market have shrunk significantly. Even the rising market is the game of the original funds in the market, and the profit-making effect is getting smaller and smaller. The funds outside the market are waiting and waiting. Only when there is a wealth making effect, can the funds outside the market have the impulse to come in

Fifthly, new ways of playing appear constantly. As the effect of making money is getting smaller and smaller, new leeks become old ones. Traditional harvesting methods are difficult to cut down the order. Only by making some innovations can leeks flock to the market. Fcoin trading, mining, firebull video and so on, has made a small number of people rich and at the same time, it has made a large number of people miserable. In essence, these projects are all capital games of drum beating and flower passing, with no change in dressing or soup. The earlier we participate, the more accounting we have. When we wait for leeks to participate, they are basically in the middle and late stage. If we put money in, they will be harvested. I, fcoin, because I participated earlier and made a small profit, but firebull participated later and was cut as soon as I went in. Fortunately, I only tried to cast a little bit

Will the market rise again? The answer is yes. In two ways. On the one hand, blockchain is the trend in the future, which has formed a consensus. It is said that there is a rule that can prove whether a technology can become a trend in the future. It depends on whether the number of articles published on this technology can multiply every year. Blockchain is fully in line with this rule. On the other hand, as mentioned above, the current market is mainly capital market. So even if blockchain is not the future trend, it will still come out of a good market. Because the characteristic of the capital market is that when the capital enters the market, the market will rise, and when the capital withdraws from the market, the market will come down, and there is no reason for the capital to enter or leave the market. At present, there are not only retail investors, but also large investors and institutions in the market. What is covered is not only leeks, but also makers who cut vegetables but did not cut them. No matter who is in the currency circle, there is only one purpose, that is to make money. If the market doesn't rise, there will be no big money making effect. If it falls for a long time, it will rise. This is an irrefutable law. Of course, whether indivial investors can make money depends on their own fortune

future plans:

first, the best policy. Strictly control the position, adjust the layout and stay away from the air currency. Position control is always the first and the lifeline of investors. After losing money, we realized the importance of position control. Now I really regret that if I didn't enter the warehouse, I wouldn't be so deep. So far, decisively clear all the air projects, and more or less free up a little money. Then, select a few high-quality projects to make fixed investment, if the funds are not enough, a small part can be disbursed from the daily income. To do this well, we need to make up an important link, that is learning. In the past, I didn't know whether the project was good or bad, but I didn't learn enough and my skills were shallow. It's better to focus on study than on reading the market, consulting the public number and asking for information. The accumulated knowledge and skills are also a kind of wealth, and no one can take them away. It is necessary to learn the basic knowledge of economy, finance and investment, as well as the knowledge of blockchain. I have read some books (general knowledge of economics, one course of economics, Xiangshuai's finance course at Peking University (I get a subscription, but I can't provide an electronic version), buffet's rule, buffet's Guide to read financial report, blockchain technology guide, decoding blockchain complete works), and give the link address (link:

Second, the medium strategy. Do oversold rebound. Small earning effect does not mean no earning effect. We must invest small funds in one or two projects, and we must go in and out quickly when there is a sharp drop and most people feel panic. We must not be in love with war You can focus on one or two big public accounts to judge the panic of the market.)

Third, the worst way. Make a wool party. On the premise of not wasting energy, it's OK to get candy and some welfare. In the current market, grasshopper is also meat. The traditional way of getting candy is too cumbersome. We found two candy delivery platform projects, one is the fulcrum:

the other is the ant Miner:

the former airdrops all kinds of candy from time to time, and at the same time has the social attribute of the community. It operates in a systematic way and obtains the strategic investment of coin safety and fire coin; The latter is a brand new candy game platform of candy world, which accumulates candy in the form of chicken laying game. It is reported that it has just won the strategic investment of gbls (Global sleepless blockchain Leaders Summit)

in addition, some dapps in the testing stage are also worth a try. Anyway, it doesn't involve any energy. It's just a way to relax after work. Fighting video (IOS version: https://fir.im/51ds Android version: http://a.app.qq.com/o/simple.jsppkgname=com.xysk.mvpart.douxi , invitation code: wn4viz), focusing on the vertical segmentation of professional artists, fans can accumulate star power and sign in every day to get stars. Stars can be exchanged for prizes or sold in private. October is the right time to go online

6. Now there are crowdfunding, just change their contract account number

7. 1. The value of bitcoin does not lie in its computing method and encryption algorithm. 2. The calculation and proction of bitcoin need time, equipment loss and electricity cost. 3. The total output of the algorithm is limited. 4. Some foreign and domestic objects have supported bitcoin payment, which makes it have the preliminary property of currency. 5. There is no difference between bitcoin and the legal currency of any country in its own value. A piece of printed paper or PVC does not have actual value. It can not have the characteristics of rare metals like gold. 6. The biggest risk of bitcoin is that no country, bank, military or government can guarantee its credibility. 7. At present, it seems to be just a virtual currency with speculation value. 8. Its circulation value is certainly not as popular as q-coin in China. For example, few people in second tier cities know about bitcoin, let alone let it admit its value.

8. There are risks. Why is the account unfrozen
do you have any illegal operations
if you don't do anything, how can your account be frozen
can blockchain software bring you excess revenue
is it worth $50000
money will not be lost in vain. The money in your hand is real.

9. The data storage mode of blockchain is actually "block" + "chain". This is like our diary, each page is a piece of paper, on which useful text information can be recorded, but each page will have a page number to record the order of each page. In contrast, a block is "paper" to record all the value exchange activities that took place ring the creation period. Page numbers are "chains" that store blocks in the database in chronological order.
