10 common categories of blockchain games

1. 1. Encryption rabbit - Xiaomi "blockchain game project" 2. Encryption dog - langang "blockchain game project" 3. Blockcat - 360 "blockchain game project" 4. Netease Zhaocai cat, star - Netease "blockchain game project" 5. Leitz dog network "blockchain game project" Chongqing anonymous technology is OK, many of them are doing

2.

From the current mainstream blockchain projects, blockchain projects are mainly divided into four categories: the first category: currency; The second is platform; The third category: application category; The fourth type: asset token

currencies mainly act as the "exchange media" in the field of blockchain assets, and the exchange media refer to general equivalents, such as gold and silver bills in the past< (currency exchange on trading blockchain assets)

platform projects refer to the establishment of technical platforms to meet the needs of various blockchain application development, which can rece the threshold of application development on blockchain

application projects cover a wide range of fields, including finance, social networking, games, property rights protection, etc., and are also the fastest growing fields of blockchain assets

asset token project refers to the blockchain mapping of physical assets, that is, the physical assets on the chain. At present, there are no more than 10 varieties

01 currency

the first category is currency project, which is also the earliest blockchain project. Currency projects mainly include bitcoin and lightcoin. In addition, there is another kind of asset with the characteristics of anonymity. Its main functions include protecting the privacy of both sides of payment while realizing payment. The well-known ones are dash, monero and zcash. Currency is mainly used as the "exchange medium" in the field of blockchain assets. The exchange medium is the general equivalent you use to exchange goods. For example, gold, silver and silver bills can be used as the exchange medium in the past. At present, there are more than 2100 types of digital assets in the world, and the number of currency blockchain projects has increased rapidly recently. As of June 2018, bitcoin is still the largest market value

02 platform type

the second type is platform type blockchain project. The main function of platform type blockchain project is to establish a technical platform to meet the technical requirements of various blockchain application development; In short, platform applications allow developers to directly issue digital assets and write smart contracts on the blockchain. Smart contract is a computer program running on the blockchain database, which can be automatically executed under the conditions of its source code setting

for example, you develop a smart contract based on the house rent protocol on the blockchain. When the owner receives the rent, it will trigger the automatic execution and give the security key of the apartment to the tenant

the main function of platform blockchain projects is to establish the underlying technology platform, so that developers can do application development on the underlying technology platform. A considerable number of platforms are still in the development state. As of June 2018, Ethereum has the largest market value

03 application

the third category is application blockchain projects. Application projects are blockchain projects based on blockchain development platform (such as Ethereum), which can solve many problems in various fields of the real economy

for example, augur, Golem, vechain, omisego, which provides asset exchange and transfer services. Using blockchain technology, these projects can better solve the problems of trust and cross-border circulation. At the same time, using smart contracts and tokens on the blockchain, they can better realize automatic execution and greatly improve the efficiency of social and economic activities. Application blockchain projects cover a wide range of fields, including finance, social networking, games, property rights protection and so on. It is also the field with the fastest market value increment of blockchain projects at present

04 asset token

the fourth category is the asset token blockchain project. Asset token refers to linking the blockchain assets to physical assets such as gold and US dollars, which is the blockchain mapping of physical assets. As of February 2018, there are no more than 10 varieties. The typical representatives are usdt against US dollars, digix Dao against gold, Digix each token represents 1 gram of Gold Certified by the London Bullion Market Association. Asset token has the advantages of convenient transaction and safekeeping. First of all, asset token is more convenient for transaction. Because blockchain assets can be split, it has better liquidity

for example, at present, real estate needs to be transferred as a whole. If the real estate can be token, it can be split and purchased, which is more convenient for transaction. Secondly, the token of physical assets is more concive to custody. Gold is easy to wear out and cause losses in physical transactions, but there is no need for physical transfer after the token of physical assets, which is more concive to the custody of physical assets

3. 1. Public chain, no official organization and management organization, no central server, participating nodes freely access to the network according to the system rules, not controlled, and work based on consensus mechanism among nodes Subversive: absolutely credible and open) < br > typical case: digital currency represents bitcoin < br > 2. The private chain is built within a group. The operation rules of the system are set according to the requirements of the group, and the modification or read permissions are limited to some extent, while maintaining the authenticity and partial decentralization of the blockchain Typical case: R3 < br > 3. Alliance chain, jointly initiated by several institutions, is between the public chain and the private chain, and has the characteristics of partial decentralization. The read permission on the fast chain in this area may be public or partially public, that is to say, multiple pre selected nodes are designated as bookkeepers internally, and the pre selected nodes compete for bookkeeping permission, Other access nodes can participate in the transaction, but not the accounting process The abilities of the candidates should not be uneven< Br > (relatively credible and open) < br > existing cases: Super ledger < br > example:? In the case of loan diversion, when the user jumps to the other party's website for registration through our link, the docking party can choose to cheat and say that it has not received the user's registration request. However, if we put the user registration behavior into the block, if the docking party wants to receive the user registration behavior, it must pay us at the same time.

4. Hot in progress! Now the most popular blockchain game: "ether clown" wonderful online! As a pet that people love, in addition to "beauty", there are many characteristics, such as being coquettish [hee hee], working to make money [too happy], being able to tease a younger sister to have a baby [insidious] [color] every clown 129313; Are unique, with a very high collection value!

6. A new resolution initiated by representative Adam kinzinger, a Republican from Indiana, has been submitted to the US House of Representatives, calling on the government to formulate national policies on emerging technologies, including digital currency and blockchain technology
the resolution calls on the idea of bitcoin, but does not directly mention its name. Instead, it calls it "alternative illegal currency". Blockchain technology is the key point, which points out that this technology has the potential to "fundamentally change" the way trust and security are built on online transactions
but in fact, the United States has not taken action to formulate this rule. However, there is a global blockchain alliance R3 in the process of formulating the standard for the use of blockchain. Of course, blockchain is just a technology that can be used by any enterprise. In China, there is a project called decent, which is more avant-garde. It uses blockchain technology to build a decentralized content publishing platform, but it may encounter some problems in China.

7. The foreign exchange market is the largest financial market in the world, and the average daily capital flow far exceeds that of other financial markets such as stocks and bonds. However, even if there is a god like existence, for some of us, it is also the "most familiar stranger", who only hears its prestige but does not know its true appearance, let alone participate in it. Today, we are going to popularize the nine basic knowledge of foreign exchange< What is foreign exchange
foreign exchange refers to the foreign currency held by a country and the means of payment expressed in foreign currency for international settlement
the concept of foreign exchange can be divided into static and dynamic
1. Static concept
the static concept of foreign exchange refers to the payment means in foreign currency that can be used for international settlement. This means of payment includes credit instruments and securities expressed in foreign currency, such as bank deposits, commercial bills, bank drafts, bank cheques, long-term and short-term government securities, etc
2. Dynamic concept:
the dynamic concept of foreign exchange is a kind of specialized business activity that changes one country's currency exchange into another country's currency in order to pay off international creditor's rights and debts. It is the abbreviation of international exchange
here, it should be pointed out that the currencies of some countries are not freely convertible in the international market, so they can only be counted as foreign currency, not foreign exchange< What is the exchange rate
exchange rate, also known as exchange rate, refers to the price of one country's currency expressed in another country's currency, or the comparison between the two countries' currencies. Usually expressed by the exchange ratio between two currencies. For example: USD / CNY = 1 / 7.2456, that is, the exchange rate between us dollar and RMB is 1: 7.2456, which can also be said that 1 US dollar needs to be purchased with RMB 7.2456< Third, the characteristics of the exchange rate
EUR 0.9705
JPY 119.95
GBP 1.5237
CHF 1.5003
2. The minimum change unit is one point, that is, the change unit of the last digit
EUR 0.0001
JPY 0.01
GBP 0.0001
CHF 0.0001
3. The rise and fall are described by "dots"
according to market practice, the price of foreign exchange rate is usually composed of five significant figures, which are counted from the right to the left, and the first one is called & quot; X dots;, It is the smallest unit of exchange rate change; The second is called & quot; X ten points;, And so on
for example: 1 euro = 1.1011 US dollars; 1 dollar = 120.55 yen
the euro against the dollar changed from 1.1010 to 1.1015, saying that the euro against the dollar rose by 5 points
the dollar against the yen changed from 120.50 to 120.00, saying that the dollar against the yen fell by 50 points< (4) the pricing method of exchange rate
1. Direct pricing method
direct pricing method is a method of expressing the exchange rate of a certain unit of foreign currency in domestic currency. Generally, how much foreign currency of one unit or 100 units can be converted into domestic currency. At present, most countries in the world use the direct pricing method, and China also uses the direct pricing method, such as the US dollar to RMB ratio is 1:6.4906.
2. Indirect pricing method
indirect pricing method is the foreign currency to express the exchange rate of a certain unit of domestic currency. Generally speaking, how much foreign currency can be converted from one unit or 100 units of local currency. At present, only a few countries in the world use indirect pricing method, such as British pound, euro, Australian dollar, New Zealand dollar and Irish pound. For example, for the UK, the exchange rate of pound sterling to RMB is 1: 9.4471, which is the indirect pricing method< What are the main procts and symbols
according to international practice, the name or code of currency is usually represented by three English letters
US dollar: USD
British Pound: GBP
Euro: EUR
Japanese Yen: JPY
Canadian Dollar: CAD
Swiss Franc: CHF
Australian Dollar: aud
New Zealand Dollar: NZD
6. Who are the market participants
participants in the foreign exchange market mainly include central banks, commercial banks, non bank financial institutions, broker companies, self dealers and large multinational enterprises. They trade frequently with huge amount of money, and each transaction is worth several million dollars or even more than ten million dollars. Generally speaking, there are three motivations for their participation:
1) through trade and investment, international enterprises convert foreign profits into domestic currency
2) for hedging, the finance director and fund manager will also use the foreign exchange market to rece the risk of price fluctuation in futures trading< 3) speculative profit< What are the major foreign exchange markets in the world< At present, there are more than 30 major foreign exchange markets in the world, which are distributed in different countries and regions on all continents of the world. Among them, the most important are London, Frankfurt, Zurich and Paris in Europe, New York and Los Angeles in America, Sydney in Australia, Tokyo, Singapore and Hong Kong in Asia< 8. Trading hours of major foreign exchange markets. Each foreign exchange market in the world alternates with each other in business hours, forming a circular operation pattern< 9. What are the ways to buy foreign exchange
1. Bank. At present, many banks can handle personal settlement and sales of foreign exchange business, foreign exchange settlement of trading companies, personal purchase of foreign exchange for overseas travel expenses and other non speculation foreign exchange situations also choose to go to the bank to apply for foreign exchange
2. Platform dealers. At present, China has allowed indivials or institutions to exchange foreign exchange online. Indivials or institutions that speculate in foreign exchange can trade foreign exchange through platform dealers.

8. Blockchain digital currency investment has risks

9. With the popularity of blockchain, blockchain games are also developing rapidly. What is blockchain game? Blockchain game is a new type of game integrating blockchain technology and concept. According to the types of "chain", blockchain games are generally divided into four categories: Ethereum games, chain game, public chain games and private chain games
Ethereum game: the underlying logic of the game is based on Ethereum blockchain and smart contract
chain game: the underlying logic of the game is based on thunderbolt cloud blockchain technology
public chain game: anyone can view the data on the blockchain and initiate transactions, open source code, decentralized blockchain management, and use algorithms and other system mechanisms to achieve the purpose of transaction and data tamper prevention without exposing too much privacy, such as bitcoin, Ethereum, etc
private chain game: similar to public chain, distributed database, point-to-point transaction, but not everyone can read, write and audit block data. The owner of the database is a separate group or enterprise. In extreme cases, the owner can cover or delete the block. In short, private chain is not completely decentralized
if it is divided by game type, it can be the same as the traditional way. At present, the existing types of blockchain games in the market include: cultivation, role play, simulation operation, sandbox, set and change cards, placement, war strategy, leisure competition, etc. With the development of blockchain, it is believed that there will be more types of games embracing blockchain, and there will be more and more types of blockchain games
as the name suggests, blockchain game refers to the game that uses blockchain technology. Because the game requires high accuracy of data and is not allowed to be tampered with, it completely gives the game rights to the players and is not controlled by the centralized platform, so it is perfectly combined with blockchain technology. Dr dragon hunt is a typical blockchain game. I hope it can help you.
