Digital currency POS mode reward halved
first line: mining, mining machine, mine (ore pool)
all three are related to mining, but they are also different
Mining: we don't discuss the technical details here. From the perspective of profit, mining has the lowest threshold. Even if we need professional mining machinery now, we can still buy a mining machine to make money. If we become bigger, we can open a mine. Without talking about the risk, mining is the simplest way to make money. The investment cost is low, the rate of return is high, and the time cost is high
mining machinery: the business of manufacturing mining machinery is very hot, and there is a high threshold, so it is difficult for non professionals to become manufacturers. Ant mining machine in the bull market does not worry about selling. Especially after 1994, as far as I know, foreign domestic ore feeders were towed away by trucks. However, the threshold of manufacturers is already very high, and it is difficult for ordinary people to get in touch with them, so there are two dealers. Mining business contact is not much, the second-hand market seems to be very chaotic
mines (ore pools) of course, mines and ore pools are inseparable. Why? The mine pool exists in order to avoid the risk of the mine. The mine pool will pay the cost of the miners according to the time according to the calculation force. Of course, it also needs to draw a percentage, and the miners will be able to keep their income from drought and flood. But the only thing to do is to bring people to the mine. Offline mines are also managed by their own machines, and can also be managed by others. There is a certain threshold, risk and income coexist
second line: information platform, exchange, wallet, currency speculation
consulting platform: something that must exist in the Internet era, providing information and consulting aggregation. The first thing new people come into contact with is information media. In the 17 years since the outbreak of digital currency, bitcoin's Internet search index has exploded. Many people want to know about digital currency, so such an information platform is sure to survive. Drainage, content, value realization and value extension are generally the ways of making profits
exchange: the best understanding is that all flows and proction currencies are for trading. Only when a transaction has a price can it be valued. Many problems will also be found in the transaction, such as the famous "bitcoin expansion". Only by finding and solving problems can the instry develop better. We all know the mode of making money in the exchange. It's the makers who make money. It's just like casinos and securities dealers. They lose more money and earn less, but the exchange is stable. In addition to the handling charges, it seems that the money charge is also a profit model. The threshold of the exchange is also high. In addition to trading risk and platform risk, it pays more attention to policy dynamics. Big exchanges now have "currency exchange", "fire currency" and so on
wallets: both hot and cold wallets are procts, and coin circles are just needed for this kind of procts. Online wallet is generally free, and then through other ways to make money, such as usually do exchanges, or there are investment activities
currency speculation: simple speculation, uncontrollable risk, too many factors affecting the price. We can envy the good luck of others, but we should not hope that we have such good luck. Therefore, there are generally three modes of currency speculation, which can be more "smart" to avoid risks: 1. Fixed investment 2. Quantitative trading 3. Arbitrage: spot move brick, futures arbitrage. Now, it seems that there is a fourth kind of profit margin in the OTC channel.
POW: full name of proof of work
pos: proof of stake
both of them are the consensus mechanism of blockchain and the bookkeeping method of digital currency
the difference is:
1. POW mechanism: workload proof mechanism, that is, the proof of workload, is the requirement that must be met when generating a new transaction information (that is, a new block) to be added to the blockchain. In the blockchain network based on workload proof mechanism, the ability of nodes to obtain the correct numerical solution to generate blocks by calculating the numerical solution of random hash hash is the specific performance of node computing power
POS mechanism: the proof of rights and interests requires the certifier to provide a certain amount of ownership of cryptocurrency. The operation mode of the proof of rights and interests mechanism is that when creating a new block, the miners need to create a "currency right" transaction, and the transaction will send some coins to the miners themselves according to the preset proportion. According to the proportion and time of token owned by each node, the equity proof mechanism reces the mining difficulty of nodes proportionally according to the algorithm, so as to speed up the speed of searching for random numbersextended materials:
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
At present, whether a digital currency is a valuable currency basically belongs to the "angel wheel" stage. There are three criteria to determine whether a digital currency is a valuable currency: one is the team, the other is the economic model, and the third is the instry demand
The randomness of theteam is too great, so we will not discuss it here. This paper first makes a detailed analysis of the economic model of digital currency. In the following article, the author will analyze some digital currencies according to different instries
Strictly speaking, the economic model involved in this paper is not completely equivalent to the concept described in economics. Especially in digital currency, currency consensus mechanism and incentive mechanism Consensus mechanism is the strategy and method for each node in the blockchain system to reach an agreement, which should be selected flexibly according to the different types of system and application scenarioscommon consensus mechanisms include pow, POS, dpos, pbft (and its variants), etc. In addition, based on the different application scenarios of blockchain technology and the characteristics of various consensus mechanisms, this paper evaluates the technical level of various consensus mechanisms according to the following dimensions:
A) compliance supervision: whether super permission nodes are supported to supervise the nodes and data of the whole network
b) performance efficiency: the efficiency of reaching a consensus and being confirmed
Resource consumption: CPU, network input and output, storage and other computer resources consumed in the process of consensusd) fault tolerance: the ability to prevent attacks and fraud
1 instry background
looking for Instry pain points: asset management needs professional team and knowledge, but now most digital currency investors do not have it; The fluctuation of digital money market is huge, and investors can't keep the value of assets in the falling market
2 own advantages
in the stock and futures markets for many years, has a mature and high-quality asset management team; AI big data team has strong technical strength
3 Market Research
after market research, it is estimated that the market value of asset management will be about US $1 billion in the next five years
4 total amount of digital currency
after considering the expected asset management market value, development cycle and difficulty, we will consider issuing 2 billion pieces of XT based on Ethereum erc20 digital currency, and never issue additional ones
5 allocation method
early stage investors hold 10%, teams hold 20%, business operation 10%, community construction 10%, and investors hold 50%
6 digital currency release / repo mechanism
the release mechanism can be divided into three categories:
the first category: the money holding part of business operation is fully unlocked, and the purpose is limited to business and operation activities
the second type: the release mechanism of community construction is that community members release exclusive information, cooperation platform release exclusive project progress and so on. According to the number of participating IDS, the corresponding proportion of XT is released (publishers and participants get 50% each) until all the releases are completed (after the release, the follow-up reward comes from the platform profit pool)
the third category: investors hold the mainstream digital currency, conct asset management in the platform, release a certain amount of XT according to the exchange ratio, and the early investors and the team hold part of it synchronously and unlock it according to the proportion
the repo mechanism is: 50% of the profit (in XT) will be returned to the holder; The rest goes into the platform profit pool, and 50% of XT in the profit pool is destroyed monthly until the total number of XT is 1 billion; The rest will be used as platform ecological construction fund
7 digital currency equity
profit sharing: holding XT is for platform users, and they can enjoy 50% of platform profits
platform Governance: participating in platform activities, enjoying XT awards and airdrop activities of other project parties
function customization: Based on platform AI big data, investors can purchase services optimized for indivial trading strategies
Sec (social economy chain)
Chinese name : social e-commerce chain
sec, the next generation of e-commerce blockchain protocol based on social trust, is the world's first blockchain system to promote the socialization of e-commerce. In essence, SEC establishes the trust foundation of e-commerce indivials through distributed bookkeeping transaction relationship and trust endorsement, and takes it as the basis of consensus. SEC main chain can be used in commodity trading, second-hand commodity trading, virtual commodity trading, commodity equity, commodity crowdfunding and other fields. Under the strong wind of the social e-commerce instry, the SEC team will focus on the social e-commerce field based on its own technology and user data

online exchange : 1
after the transfer of user terminals from PC to mobile phone, the e-commerce form has reached a new turning point, and is rapidly moving towards mobility, fragmentation and socialization. In three years, social e-commerce has occupied 14% of the market share of the whole e-commerce, with an annual growth rate of more than 100%. Once the share exceeds 20%, the replacement of traditional e-commerce will accelerate, just as traditional e-commerce will squeeze offline retail
based on WeChat's user volume and user time in China, the Chinese mainland market has been leading the global market in terms of innovation and market size. The main modes of social e-commerce include online Red e-commerce, content e-commerce and wechat circle of friends e-commerce. In essence, the three business models are based on personal brand and circle of acquaintances to establish trust relationship, and then attract users through content display
Social e-commerce has subverted the trust mechanism of traditional e-commerce in form, but there is no new trust solution mechanism to adapt to the P2P business model of social e-commerce, which restricts the growth of social e-commerce and model innovation in a higher dimension.
