Total amount of BTK token digital currency

1.

The total number of bitcoins is 21 million

in 2009, when bitcoin was born, block reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

extended data

monetary characteristics

1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom

2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution

5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay

6. Cross platform mining: users can explore the computing power of different hardware on many platforms

2. The total number of lightcoin is three times that of bitcoin. The total number of bitcoin is 21 million, and the total number of lightcoin is 84 million

it is based on bitcoin protocol, but different from bitcoin, it can also "mine" efficiently through consumer hardware. Liteoin provides you with faster transaction confirmation (2.5 minutes on average). It uses hard memory and mining workload proof algorithm based on scrypt (an encryption algorithm). It is oriented to ordinary computer and graphics processor (GPU) used by most people. The litecain network is expected to proce 84 million currency units

one of the design purposes of litecoin is to provide a mining algorithm, which can be run simultaneously on the machine mining bitcoin. As the application specific integrated circuit (ASIC) designed for bitcoin mining (Avalon proced the world's first ASIC bitcoin miner in 2012) graally emerged, litecoin also followed the technological evolution. But before the widespread use of litecoin currency, it is unlikely that there will be an application specific integrated circuit (ASIC) specially designed for litecoin. But in fact, under the expulsion of interests, there has been an ASIC miner with scrypt algorithm, and the competition has become white hot. Many people claim that the recent decline of Leyte coin has something to do with the manufacturers of Leyte coin miner

similarly, at present, the competition among bitcoin mining machine manufacturers is still fierce. Since Avalon proced the world's first ASIC bitcoin miner, so far, it has upgraded three generations of miner chips, and the fourth generation of 28nm miner will come out soon.

3. The Chinese name of DK coin is tic coin, which is not a real digital currency and can not be listed as a noun in the mainstream currency circle. This is a typical MLM coin, which often spreads some false information. These false information can be found on the Internet
if you don't understand digital currency, don't go through this muddy water. If you are interested, you can pay attention to the mainstream digital currencies such as bitcoin, Leyte coin, doggy coin, and the tokens of crowdfunding projects on the European crowdfunding platform.

4. I can't give you an accurate answer to this question because digital currency covers too many aspects. There is also the possibility that many new cryptocurrencies are born or die every day. Now the world's more well-known digital currencies are bitcoin, dogcoin, Leyte coin, bitstock, reborn coin, Yuanbao coin, Diandian coin and so on. It is said that Ecuador, a small South American country, recently created its own official cryptocurrency
according to incomplete statistics, more than 200 counterfeit coins have been proced since 2014, and more than 100 have survived. The life cycle of Shanzhai coin is generally about 2-3 months. Because the purpose of some Shanzhai coins is to earn money without any innovation. When the price is high enough, the makers will sell a lot to cash out. Without the support of the makers, this kind of counterfeit money will eventually die.

5. One of the controversial attributes of bitcoin is its fixed supply. At present, 25 new bitcoins are proced every 10 minutes, and the number is halved every four years. Overall, there won't be more than 21 million bitcoins & gt;. On the other hand, each bitcoin can be divided into 100 million shares (each is called 1 "cong"), if one cent is enough to buy a car, it will be troublesome to trade in US dollars, but even if bitcoin rises to the level of US dollars assumed above & gt; We will not encounter such problems. Therefore, in short, the total number of monetary units that will always exist is 2100 billion, that is 2100 trillion, or 250.899. In the square of choosing this value & gt; In fact, Nakamoto is much luckier or smarter than most people realize. First of all, this number is far less than 264-1, which is the largest integer that can be stored in the form of standard integer in a computer. If it exceeds that value, & gt; The value will return to zero like a odometer
secondly, however, there is a smaller threshold for the total number of "smart": the largest possible integer that can be represented in floating-point format. Integers are not the only numbers that computers can store; To deal with decimals, computers & gt; Use a format for floating point representation. Floating point notation is essentially a binary version of scientific notation. For example, here is a value you will encounter when you study physics:
mass of the earth: 5.972 1024 kg
mass of the sun: 1.989 1030 kg
speed of light: 2.998 108 M / s
light year: 9.460 1015 m
mass of proton: 1.672 10-27 kg
Planck length: 1.616 10-35 m
we can notice that, How does scientific notation allow you to represent all of these values with reasonable accuracy, even though they vary greatly in size. Floating point notation is essentially a binary scientific notation; When you store numbers & gt; When the word is 9.625, what your computer stores is "1.001101
* 1011" (in other words, it stores 0100000000100011
& gt; This is the same thing with high-precision sequence form). In this high-precision form, the coefficient (that is, the part that is not the exponent) has 52 bits. This means high precision (more refined & gt; Double precision floating point number is enough to store up to 253 numbers, but it can't be any higher. If it exceeds 253, you have to start cutting off the numbers at the end. Bitcoin's 250.9, the total number of "smart" in the form of index, is just & gt; OK, below this maximum
if we have integers, why should we care about floating-point values? Because more high-level programming languages (such as JavaScript) do not open low-level "floating point" and "integer representation", but only provide "number" representation for programmers; Concepts
– of course, in floating-point form. If Nakamoto chose 210 million instead of 21 million at that time, bitcoin programming in many languages would be much more troublesome than it is now
note that Stefan Thomas unfortunately didn't notice this in time when he wrote bitcoinjs, so that the library used a special "big number big
number" object instead of an ordinary number to store the tutorial output value; My own bifurcated bitcoin JS (along with other improvements) uses ordinary numbers.

6. BTT is the incentive token on BitTorrent (bitstream), and Chinese is the stream token. For BitTorrent, the early Internet practitioners are very clear. At that time, the network download was very slow, and many students would use BT download resources in dormitories. This protocol enables client software endpoints to cooperate with each other, so as to efficiently and reliably distribute large files to multiple clients. The more users download, the more users, The faster the speed is, BitTorrent can be regarded as the originator of decentralized system application
BitTorrent was originally a point-to-point distributed communication protocol born in 2001, with more than 100 million users. Last year, the Tron foundation officially issued a community open letter, announcing the acquisition of BitTorrent company, which marks the strategic partnership between BitTorrent agreement and Tron wave blockchain agreement

in 2001, Bram Cohen invented the BitTorrent agreement. On September 22, 2004, BitTorrent company was established. On July 24, 2018, Tron foundation completed the acquisition of BitTorrent company. On January 20, 2019, BitTorrent token (BTT) was issued on Tron. On January 28, 2019, BTT was put on sale in binance launchpad
Bram Cohen, also translated as Bram Cohen, is known as the father of BT and a computer programmer in the United States. His software BitTorrent makes him famous. He is also one of the founders of codecon, the organizer of bay area P2P hackers conference and the writer of codeville. What's more famous is that he personally developed and designed the famous game platform steam. In history, BitTorrent once appeared as a rule breaker, which has a profound impact on the Internet. At the peak of 2006, BT traffic even accounted for 70% of the total network traffic, and almost all the download software we use now is improved on the basis of BT. However, e to the business model and other reasons, BitTorrent failed to become a profitable company. On the 30th day after BitTorrent was acquired by BoChang, the founder Bram Cohen announced his resignation. At present, the actual controller of BitTorrent is sun Yuchen

7. The total amount of money in DCEP is not constant

why

let's take a look at the current definition of DCEP

Digital legal tender

in addition to being different from legal paper money in carrier, it has the same function as paper money: value scale, circulation means, payment means and value storage

this is also the function of paper money

the issuance of DCEP is based on 100% reserve and will circulate with cash currency, that is, M0 issuance

although the central bank's digital currency was slowly launched after the rise of blockchain technology, it is not pure blockchain technology, but only uses some technologies related to blockchain

we all know that the commercial application of block chain technology still faces many problems, such as concurrency, data storage and so on

a country with a large population like ours, if we use blockchain technology in a strict sense, it will not be able to carry it at present<

Wanxiang blockchain analysis:

from the information disclosed by the people's Bank of China, DC / EP does not use the real blockchain like Libra

although digital currency is not a token in the blockchain, it is similar to the token in the blockchain in the key features of non double flower, anonymity, unforgeability, security, transitivity, separability and programmability

therefore, DC / EP still belongs to token paradigm rather than account paradigm

the central bank is responsible for the maintenance of the DC / EP issuance registration subsystem, which is centralized and does not need to run consensus algorithm, so it will not be subject to the performance bottleneck of the blockchain

in DC / EP, blockchain is used to confirm the right registration of digital currency and plays an auxiliary role

each country's base currency issuance is increasing every year

therefore, the central bank's digital currency improves the bearing property of money. Paper money is naturally suitable for the atomic world, and digital currency is more suitable for the consumption scenarios in the bit world

the supply is definitely the same as that of the previous monetary system, increasing every year.

8.

BTD, fully known as "bitdisk", is a digital storage system that can provide users with pictures, videos, music, files and other data

BTD has the same functions as network disk, Tencent micro cloud and 360 network disk. The difference between BTD and traditional network disk is that it is built with blockchain technology, which makes the data stored by users more secure

BTD is a global distributed shared storage ecosystem based on blockchain, headquartered in the garden city of Singapore, and the domestic operator is Guangzhou Chaomi Information Technology Co., Ltd. On April 21, 2019, bitdisk, the world's first blockchain cloud disk based on BTD storage chain, has been officially released. Bitdisk has the same functions as the network disk, but the blockchain technology makes the files stored in bitdisk more private and secure, and the remote disaster recovery more secure

The characteristics of BTD are as follows:

1. Users can enjoy mass storage system after registration

2. At the same time, users can provide their own computer hard disk as BTD point-to-point storage system, so as to obtain the platform's "mining" digital currency award, the token name is "BTD", this digital currency uses the encryption data algorithm, which can flow to the market

3. Of course, the above-mentioned reward of providing your own computer hard disk to BTD platform as a point-to-point storage system is just a drop in the bucket for promoters. You should know that the registration income of participating in BTD promotion can be quite considerable. You only need to register as a member of BTD platform and invite new users to register, and you will get the corresponding BTD digital currency reward. The key point is free, No franchise fee, zero threshold to join< br />

9. Digital currency is an alternative currency in the form of electronic currency. It is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community

it is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currencies, such as bitcoin, lightcoin and ppcoin, are electronic currencies created, issued and circulated by means of check sum cryptography.
