Background and development of ADA digital currency

1.

what is digital currency

digital currency can be used to describe all electronic currencies, including virtual currency and cryptocurrency. Digital currency is a kind of electronic currency without any physical form. Because of its functions and inherent attributes, it is the same as the standard illegal fixed currency, and can also be referred to as the network version of cash. Digital currency is invisible. People need to use and hold it through devices that can be connected to a specific network

T1: eth (the first public chain at present, the underlying platform of Shanzhai coin breeding, and in the speculation of eth2.0) EOS (community consensus + DAPP possible explosion + defi can also join + drop out of high cost performance) Zec (anonymous leader)

T2: Yas (UBI concept, low market value, great potential) atom (cosmos, advantage new public chain), XRP (the decline in 2019 has not risen, so the upward space is still very large) Polkadot dot (Boca, the goal is to surpass Ethereum) KSM (Boca pioneer)

T3: Ada (potential) NEO (myth of 1000 times of the last bull market), ont (strong village), Iost (Iost is currently undervalued, DAPP is also in good development)

there are platform coins in the coin circle, corresponding to HT, BNB, MX

1. Enjin (enj)

in the near future, the game instry is the instry most likely to adopt blockchain on a large scale. Enjin coin is the cryptocurrency of virtual goods created by Enjin. Enjin is the "largest online gaming community platform" with more than 250000 gaming communities and 18.7 million registered gamers

Cardano (ADA)

compared with Ethereum, EOS and Tron, Cardano is the third generation of decentralized app (DAPP) and smart contract platform. Cardano's design philosophy has the following points:

scalability: with the growth of users, the transaction processing speed is not affected or even faster, such as P2P protocol

interoperability: in the future, there will be countless devices connected to each other, instead of only connecting and forwarding through routers. All kinds of devices can communicate directly through standard general protocol

Sustainability: like bitcoin, Cardano project will not be controlled and influenced by a certain company or organization, which is a safe, decentralized and sustainable development platform

With the popularity of sto (security token offers), Nash also plays an important role. Nash is a kind of registered security token. In the past, Nash participated in and led the development of many projects

Nash exchange is a decentralized exchange. If you hold nex token, you can calculate the dividend here

4. Basic attention token (BAT)

bat mainly solves the problem of advertising:

user information is abused: large companies such as Google and Facebook track and use user information and behavior, and sell without the knowledge of users

the effect of advertising is restrained: middlemen earn most of the fees, a large number of advertisements are blocked by users using software, and advertisements are fake

in the past six to 12 months, the number of publishers using the brand browser (Note: the brand browser supports bat token) has grown rapidly, and almost no blockchain ecosystem has grown so fast

5, chainlink (link)

chainlink mainly solves the problem that each blockchain has and the smart contract cannot obtain external data. In order to introce external data into the blockchain, the concept of Oracle is proposed in smart contract

companies including Google are supporting the development of chainlink. Here is a list of chainlink partners

one of the main problems of chainlink is similar to Ethereum. The development team has reserved 650 million link tokens, while only 350 million are in circulation at present

Ethereum (ETH)

Ethereum has long occupied the second place in the top 100 cryptocurrencies. Its ecology is so big that we can't call it altcoin now. To tell you the truth, I'm not optimistic about Ethereum in the long run, but it will flourish in the short run

3. Here's a brief introction to several mainstream digital currencies to give you a rough idea. After that, I will talk about the specific currency from time to time

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.

4. Virtual currency ranking

the ranking of digital currency can be measured according to multiple dimensions, such as market value, technical ability, landing in Cheng, 24-hour rise and fall, 24-hour turnover list, 24-hour turnover rate, etc. For the sake of data accuracy, we list the ranking of virtual currencies in the market value list<

let's first look at the data to see how the Ministry of instry and information technology measures the value of digital currency:

saidI Research Institute of the Ministry of instry and information technology officially announced the first global public chain technology evaluation index and ranking. Eth ranked first with a total index of 129.4, while BTC only ranked 13th<

moreover, the ranking method this time is that CCID Research Institute of MIIT does not mention cryptocurrency, but only public chain. The first list of evaluation objects are: bitcoin, Ethereum, reborn, Leyte, bitcoin cash, Cardano, starcoin, Neo, eota, Monroe, dasey, Xinjing, Ethereum classic, quantum chain, Nanor, application chain Big zero coin, verge, stratis, cloud storage coin, stim coin, bitstock, byte coin, wave coin, deced, super cash hcash, Comodo coin, ark. The top ten in the list are eth, stem, LSK, Neo, KMD, XLM, ADA, iota, XmR and strat<

If ranked by market value, the results will be much different: the following data are based on Niuniu app, and the market value represents the first place at the time of writing: bitcoin (BTC)

current price: 26428 yuan, market value: 460.018 billion yuan, total amount of CDB: 21 million, circulation volume: 17.406 million, and circulation market value: 460.207 billion yuan, Issue time: 2009.01.03

second place: XRP

current price: 236 yuan, market value: 95.192 billion yuan, total issue volume: 100 billion yuan, circulation volume: 40.327 billion yuan, circulation market value: 95.181 billion yuan, issue time: 2011.04.18

third place: eth

current price: 734 yuan, market value: 76.136 billion yuan, total issue volume: 104 million yuan, Circulation volume: 104 million, circulation market value: 76.136 billion, issue time: July 24, 2014

fourth place: Star currency (XLM)

current price: 98 yuan, market value: 18.834 billion, total issue: 104.523 billion, circulation volume: 19.155 billion. Circulation market value: 188.43 yuan. Issue time: 2014.08.01

fifth place: bitcoin (BCH)

market value: RMB 137.700 billion, currency price: RMB 810.175, total currency: RMB 21 million, bitcoin cash released on August 1, 2017, jointly created by some bitcoin developers, belongs to the new version of bitcoin. From 2015 to 2017, the price of bitcoin rose rapidly. Different factions competed fiercely for more computer network resources. In order to get out of the competitive environment, one camp created another version and rebuilt the blockchain currency. Bitcoin cash modifies the code of bitcoin, increases the block size to 8m, adopts two-layer network, reces the workload of bitcoin network, and maximizes the efficiency of bitcoin network without damaging the original structure and security of bitcoin blockchain

with the integration of the two exchanges of okex and Huo yuan.com, yuanniuniu can share the trading depth and enjoy the treatment of zero handling charge fund transfer. It only needs to download an app to exchange transactions at both ends. At the same time, yuanniuniu is also a good market software tool, which can help speculators master the latest currency price trends and large positions.

5. First of all, what ADA does is the concept of smart contract. I think you should be familiar with smart contract, but for some new people, I still want to explain. The so-called smart contract is to write a contract that the computer can understand through the programming language, because there is no need for a third party, and the executor of the contract is a selfless computer, so it solves the problem of trust between people. For details, please refer to GitHub smart contract
Ethereum is a blockchain smart contract. Now Ethereum ranks 2-3 in the market value ranking, with a market value of 25% of bitcoin. However, Ethereum also has some problems, such as slow trading, high fuel costs and the mining mechanism that has been criticized repeatedly. Familiar? All of bitcoin's problems are with Ethereum. Some time ago, the Ethereum cloud cat game developed on Ethereum went online in the first week, directly blocking Ethereum's trading network. I tried to pay a high gas fee of nearly 100 yuan, but I still couldn't transfer it successfully. This can't help but lower my expectation of Ethereum. Ethereum is a great idea of V God, but after all, it is a pioneer, and there is a long way to go from perfection.

6. If you buy, you can go directly to the exchange. But if you ask about the investment method, it will be difficult to learn for a while. It is suggested to take a look at the recent market of bitcoin, and password finance can see the recent market and analysis.

7. Miner is composed of high-end graphics card, a miner to use a lot of high-end graphics card composition. There are a lot of loaders, so the price of graphics card will rise naturally. It's all taken to the loader.

8. At present, investing in digital currency is still a very small way of investment. The digital currency market is still in the early stage of instability, and the investment risk is high, but once there is income, it is still very considerable. There is still a lot of room for bitcoin appreciation. In addition, we can pay attention to some non mainstream currencies, see their potential, and make long-term value investment. Like pnt and ADA, they're good. I've voted for them. But pnt estimates it'll be a year later.
