What is bat digital currency
digital currency is an alternative currency in the form of electronic currency (which can be used for real goods and services transactions)
digital currency has the main characteristics of network packets. This kind of data packet is composed of data code and identification code. The data code is the content we need to transmit, while the identification code indicates where the data packet comes from and goes
based on the characteristics of digital currency, the direct benefit of digital currency to the central bank is not only to save the cost of note issuance, circulation and settlement, but also to enhance the central bank's ability to control funds
Electronic money and virtual money are called digital money.

practical significance
the digitalization of central bank's currency helps to optimize the central bank's monetary payment function, improve the central bank's monetary status and the effectiveness of monetary policy. The central bank's digital currency can become an interest bearing asset to meet the holder's reserve demand for safe assets, and can also become the lower limit of bank deposit interest rate
can also become a new monetary policy tool. At the same time, the central bank can affect the bank's deposit and loan interest rate by adjusting the central bank's digital currency interest rate, and help break the zero interest rate lower limit
operation system
fan Yifei, vice governor of the people's Bank of China, said in the article that the digital currency of the people's Bank of China should adopt a two-tier operation system. This model does not change the relationship between creditor's rights and debt of currency in circulation, does not change the existing money supply system and al account structure, does not constitute a competition for commercial banks' deposit currency, and does not increase commercial banks' dependence on the interbank lending market
will not affect the lending ability of commercial banks, and will not lead to the phenomenon of "financial disintermediation". At the same time, because it does not affect the existing monetary policy transmission mechanism, it will not strengthen the pro cyclical effect under the pressure environment, and it can improve the convenience and security of payment, and it also has the credit advantage of central bank endorsement
digital currency has the main characteristics of network packet. This kind of data packet is composed of data code and identification code. The data code is the content we need to transmit, while the identification code indicates where the data packet comes from and goes
based on the characteristics of digital money, the direct benefit of digital money to the central bank is not only saving the cost of paper money issuance, circulation and settlement, but also enhancing the central bank's ability to control funds.
bitcoin is the originator of digital currency and the most valuable virtual currency. Because blackmail virus only takes bitcoin, it has entered the public view. The soaring price of bitcoin in 2017 has attracted a large number of investors to enter the digital money market. Because the number is small, it is only 21 million, which has a strong deflationary attribute
of course, I am extremely optimistic about the future of bitcoin. Of course, many people are not optimistic about digital currency. Here, it is most pertinent to quote Krugman's view:
"at least for now, buying bitcoin is still a good investment. But that doesn't mean the experiment was successful. The original intention of establishing a monetary system is not to make those who hold money rich, but to make transactions convenient and benefit the whole economy. And none of these bitcoins came to us. "
reborn currency
a protocol currency issued by reborn, which is the base currency of reborn network. It can circulate in the whole reborn network, with a total amount of 100 billion, and graally decreases with the increase of transactions. Reborn currency is the only common currency in ripple system, which is different from other currencies in ripple system, Ripple labs (formerly known as opencoin) is the operating company of ripple coin
unlike bitcoin, reborn is a kind of transaction protocol, which is called smart contract in technical terms. It supports people to pay in any currency, and does not need a central data exchange center, so the transaction confirmation time of ripple is only 35 seconds, while that of bitcoin is 10-40 minutes
Ethereum
Ethereum is the name of currency used in Ethereum, which is used for payment calculation in Ethereum virtual machine. Ethereum is a blockchain that can be used to deploy decentralized applications. It is an open source computer platform and blockchain platform. At the end of 2013, it was founded by vitalik buterin, a Russian programmer
there is a key difference between the blockchain technologies used by Ethereum and bitcoin. Ethereum's data processing speed is faster than that of bitcoin, because once agreed, Ethereum's system will automatically apply to the terms and conditions in the contract
unlike bitcoin, the value of Ethereum depends on whether the applications on the platform of Ethereum are prosperous or not, just like the price of oil will rise with more machines using oil
bitcoin cash
bitcoin cash is a branch of bitcoin. In order to solve the problem of long transaction time of bitcoin, at 20:20 on August 1, 2017, a small number of mining machines began to use 8m block to start mining, and the transaction confirmation speed was thousands of times faster than that of bitcoin using 1m block
strictly speaking, however, there are different opinions on whether this is a new branch of bitcoin or another kind of "counterfeit currency". But now the offer of bitcoin cash is nearly 20000 yuan, so it's not too much to use it as a kind of "Shanzhai coin" to divide bitcoin traffic
IDA coin, ADA in English, is a proct of Cardano project. The total amount of Aida is 4.5 billion yuan, and 3 billion yuan will participate in the subscription. Among them, 2.5 billion ADA will be used for platform subscription, 500 million for the financial support of the development company's operating company, and 1.5 billion ADA coins will continue to be issued in the form of block awards
Cardano is a project started in 2015 to change the way cryptocurrency is designed and developed. This project is aimed at technical reformers, technical improvements to bitcoin and existing platforms. If bitcoin, Ethereum and other projects have many other shortcomings, Cardano can solve them<
lightcoin
a currency based on bitcoin protocol, but it does not require very high computing power, and it can also be mined by ordinary computer. Lightcoin's algorithm comes from the algorithm designed by Dr Colin Percival for tarsnap secure online backup service (backup for Linux and other open source operating systems)
for a long time, there has been a voice that "lightcoin will replace bitcoin", which is impossible. In the future, there will probably be a variety of cryptography currencies in the world, but any kind of counterfeit currency can not replace the mainstream position of bitcoin, no matter how excellent its algorithm is compared with bitcoin<
stellar currency
stellar currency, a digital currency project initiated by Jed McCaleb, the former founder of ripple, is used to build a decentralized gateway between digital currency and legal tender. It will be provided to users in the form of free distribution, and its supply online is 100 billion, of which 95% of the amount of star coin is used for free distribution
star is a diversified team. The board members include Keith rabois, former COO of square, Patrick collison, CEO of stripe, Jackson Palmer, co-founder of dogcoin, and naval Ravikant, co-founder of angellist, who will be the consultant of the project< New economy movement, or NEM, was founded on January 19, 2014. The founder is a mysterious person in bitcointalk.org forum called utopianfuture. The original intention of utopian future was to build a second-generation digital currency NXT. He then realized that NXT's distribution model was unreasonable, so he devoted himself to NEM with egalitarian distribution
as a kind of cryptocurrency, new coin does not need much computing resources to maintain the operation of nodes. The proof of importance (POI) engine of NEM reces the threshold of computing resources to participate in non-traditional blockchain<
dascoin
formerly known as black coin, is a kind of counterfeit currency of bitcoin, which focuses on anonymous function. There are many innovations, such as master node network, fast payment, mixed currency anonymous technology, proposals can vote, and developers have fixed budget support. The core consists of a unique incentive P2P network. Miners are rewarded for maintaining blockchain security; The main node holders are rewarded for verifying transactions, storing data and providing a variety of services
the feature of anonymity meets the needs of some investors for absolute privacy. Although bitcoin is also widely used in money laundering and other illegal transactions e to its anonymity, it is only "pseudo anonymity", and the transaction of bitcoin can still be traced back to the traders themselves.
digital currency has the main characteristics of network packet. This kind of data packet is composed of data code and identification code. The data code is the content we need to transmit, while the identification code indicates where the data packet comes from and goes
based on the characteristics of digital money, the direct benefit of digital money to the central bank is not only to save the cost of paper money issuance, circulation and settlement, but also to enhance the central bank's ability to control funds.
There is a long bridge on the beach of the tower at the bottom. You can walk to the central island and get to the second island through the central island
radiation island is an open survival game with nuclear theme, which focuses on nuclear energy again. Nuclear energy is an alternative new energy, but the panic caused by nuclear leakage is still difficult to eliminate. The game takes the distant future world as the background, the human hands have destroyed the beautiful home personally, the earth has become critical, the radiation is rampant, the weather is bad, what's more terrible is, fierce mutant zombies are everywhere, and the important task of the players is to survive in such an extreme environment
Introction:
primary Survival Guide: if you want to survive, food is essential. It is very important to get food in the 4399 radiation island game. All kinds of food and props will be randomly brushed on the map, which we can collect. It is very important in the case of lack of resources in the early stage. Of course, we can hunt animals to get food. In the early stage of survival, we can create two essential necessities in the game, furnace and bonfire, through simple operation
bonfires can be used for lighting and heating at night (it is worth noting that in the night mode, when the temperature drops, we will be fatally injured, so a bonfire is necessary. Of course, if conditions permit, sleeping directly can help you spend the night safely and quickly. In the 4399 radiation island game, the furnace can be said to be the most important thing to survive. We can refine various materials and cook in the furnace (how to use the furnace: click the furnace to enter the refining interface, and the two spaces above are the place where the articles are put in. Just put in the raw materials and fuel wood that need to be refined, and the successful refining items can be taken out in the space below)
primary survival suggestions: stone axe, stone pick, bow and arrow. In the early stage of 4399 radiation island game, stone axes and stone pickaxes can be made with very few resources. They can be used as acquisition necessities and weapons at the same time. Of course, we can also obtain resources through one handed tree rolling (this is also a small unexpected setting). Bows and arrows can also be completely obtained by simply collecting materials. You can look at the introction of manufacturing formula materials
the project carries out decentralized digital advertising business based on the brand browser, protects users' privacy through the use of zero knowledge proof, and at the same time can make users' attention get a return. There is a unique concept in the brand browser - attention. Brave uses anonize algorithm to count user behavior, such as which link to click most, or which website to stay for the longest time. These behaviors can be quantified by the unit of "attention". The specific way is to embed the blockchain ledger system in the browser, and the token circulated by this system is bat (attention token). In short, the brand browser integrated with bat token will maintain a good positive feedback relationship among businesses, website owners and users. Usually, when people watch advertisements or high-quality content, they will be rewarded with bat token because they spend their attention; The website owner successfully attracts the attention of users by virtue of advertising and high-quality content, and the system will reward them. The bat token that users and website owners get comes from the advertising expenses of businesses.
