What is blockchain game
of course, different games have different ways to play. In detail, you may need to focus on a certain game to give you an explanation. Or do you want to develop a blockchain game by yourself? I recommend Chongqing anonymous technology. Blockchain games are all in progress
are all foreign, not domestic, and there are many domestic deceptions.
What is blockchain game
there are many definitions of blockchain game at present, one of which is to write the core data into the blockchain and use the data on the chain as the source of random numbers. For example, in the previous game, the currency was decided by the game operator, but e to the decentralized characteristics of the blockchain, the transactions between currencies are transparent, and the transaction data are synchronized to each player. In this way, when the total amount of money remains unchanged, the game will get more value for money
what value can blockchain bring to the game
ownership and liquidity of game assets
on the blockchain, players can own assets in the game, and these assets have liquidity in a broader sense. In traditional games, the points, props, weapons and roles are often owned by the developers, so the centralized developers have more power to make drastic changes to these assets, or even dispose of them at will. These assets in the game can only be limited to the internal circulation of the game. Outside the game, it seems that there is no reuse value, and it is difficult to be given application scenarios again from the technical level
under the logic of blockchain, once the assets in the game are on the chain, these points, props, weapons and characters can completely belong to the player's blockchain address, and the player has ownership of this address and the assets below it. Then we can imagine a number of application scenarios:
1. Asset trading anytime and anywhere: a large number of games do not have the prop trading function. Of course, the original intention of this design is to avoid the confusion of the economic mechanism in the game, prolong the game time of users, and increase the income of developers. Assuming that the above is not the concern of developers, then "props on the chain + Mobile Wallet" can realize online and offline transactions of two users anytime and anywhere. You and your friends chat about a recent PC game ring dinner. Open your mobile wallet to see what kind of weapons and equipment each other has. The experience of completing a transaction is as simple as a wechat code scanning payment. When you come home in the evening, open the PC login game, and the transaction completion tool has already been lying in your equipment bar
2. Game asset reuse: after the assets are linked to each player's address, it is easy for developers to reuse the assets of other games for secondary transformation or cross game reuse. Spiderstore has a game called cryptocuddles, which is a cat fighting game based on encrypted cat. Players log in with their own Ethereum address, and the game will automatically get all the encrypted cats under the address. The role comes from encrypted cat, and only the fighting logic comes from cryptocuddles itself
3. New ways to get users: in traditional games, new games often need to get users again, or use old games to guide new games. Blockchain can break this way and rece the cost of getting customers. For example, the cryptocuddles mentioned above, all users of encryption cat are potential game players who can be directly converted. If the direct reuse of assets involves IP issues, developers can also design in this way. As long as the users who have cats in the encrypted cat can directly obtain certain rewards in the game, such as roles, treasure boxes, props, etc. the verification method only needs to log in with the address and read the data on the chain
in this way, a new game online can completely borrow the user drainage of the existing popular games. Isn't this kind of playing method actually a routine of issuing candy with forked coins and Airdropping new tokens? Using eth or EOS, the currency with the largest number of coin holders, to air drop their own token to the coin holders 1:1, so as to obtain users at a very low cost
spiderstore currently has more than 2000 DAPP games, accumulating hundreds of thousands of users who have played Ethereum games. If a new game needs to be promoted, the simplest way is to air drop game assets to these addresses, which is much more accurate than traditional advertising
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.
