BTC bitcoin
bitcoin is the first distributed digital asset platform created. Since its launch in 2009, it has proven to be not only the most popular, but also the largest market capital value. In addition, it is also the most expensive, with a value of $10710 per coin on February 17, 2018. Bitcoin introces the first blockchain distributed ledger dedicated to recording all transactions, and gets rid of the function that users need a central authority to process or verify transactions
its goal is to provide a platform for users to conct cross-border transactions without any intermediary, which is what we call decentralization. The platform's largest money (BTC) supply is about 21 million. Of this figure, about 16.5 million have been mined and are now in circulation. It is mined all the time around the world to ensure the circulation of coins
Advantages:1. Its distributed system provides users with great freedom
2. High portability

eth Ethereum
Ethereum is also a distributed platform, which was created by Network Programmer vitalik buterin in July 2015. Ethereum aims to enable users to create and deploy smart contracts. One of the main functions of smart contracts is to allow the creation of encrypted assets or tokens running on Ethereum networks. Ethereum token is used to purchase various functions such as cloud storage space. These tokens are stored in a digital wallet compatible with Ethereum blockchain
Ethereum's digital currency ether serves as the medium for executing smart contracts. At present, about 98 million ether coins have been mined and circulated, and the circulation supply increases by about 18 million every year. Ethernet coin is created to run on the Ethereum network. It can be used to compensate the participant nodes or transfer from one user to another

< H2 > extended data:generation principle:
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique
in the metaphor of banknotes, bitcoin is the number of the top word of a banknote. The number of the top word on a banknote owns the banknote. The process of mining is to constantly seek the special solution of the equation system through huge amount of calculation. The equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start
after completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to post the address to others, and you can pay through the same client
after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
do you remember what the consensus mechanism of bitcoin is? The consensus mechanism of bitcoin is pow. To put it simply, the more work you do, the higher the amount of computation you pay, the more likely you will be the first to find the correct hash value, and the more likely you will be rewarded with bitcoin
however, there are some defects in the pow of bitcoin, that is, it is too slow to process transactions, and miners need to constantly collide hash values through calculation, which is costly and inefficient. Friends who are interested in blockchain knowledge should see such a saying:
in order to make up for the deficiency of bitcoin, Ethereum has proposed a new consensus mechanism, called POS (this is the abbreviation of English, which means "proof of equity", also translated into "proof of equity")
POS simply means the same as its literal meaning: equity, equity. The more currency you hold, the more equity you have, the higher your equity
Ethereum's POS means that the more money you hold, the longer you hold it, the less difficult it will be to calculate and the easier it will be to mine
in the initial setting of Ethereum, Ethereum hopes to build a relatively stable system by using POW in the early stage, then graally adopt POW + POS, and finally completely transition to POS. So, it's true that the consensus mechanism of Ethereum is POS, but POS is only a plan or goal at the beginning of Ethereum's release. At present, Ethereum has not yet transitioned to POS, and the consensus mechanism adopted by Ethereum is still pow, that is, the pow of bitcoin, but it is slightly different from the pow of bitcoin
the amount of information here is a bit large,
the first information point is that the consensus mechanism currently adopted by Ethereum is also pow, but it is slightly different from the pow of bitcoin. So, what's the difference between the pow of Ethereum and bitcoin: in short, the mining difficulty of Ethereum can be adjusted, but the mining difficulty of bitcoin can't be adjusted. Just like our college entrance examination, because the teaching situation and the number of students in different provinces are not the same, so the college entrance examination is divided into national papers and provincial independent proposition
Ethereum said that I am in favor of the topic by region. Bitcoin said: No, it must be the same volume in the whole country. The difficulty is the same for everyone
the popular explanation is that bitcoin uses computer computing power to do a lot of hash collisions, enumerate various possibilities to find a correct hash value. The Ethereum system has a special formula to calculate the difficulty of each block. If a block is verified faster than the previous block, Ethereum protocol will increase the difficulty of the block. By adjusting the block difficulty, the time needed to verify the block can be adjusted
according to the Ethereum protocol, the dynamic adjustment method of difficulty is to make the time interval of creating new blocks in the whole network 15 seconds, and the network uses 15 seconds to create blockchain. In this way, because the time is too fast, the synchronization of the system is greatly improved, and it is difficult for malicious participants to launch 51% (that is, more than half) of the computing power to modify historical data in such a short time
the second information point is: in the initial setting of Ethereum, we hope to achieve the transition from POW to
POS through phased upgrade
dating back to 2014, at the beginning of Ethereum's launch, the team announced that the launch of the project would be divided into four stages, namely, Froniter, homestead, metropolis and serenity. In the first three stages, the consensus mechanism adopts pow (workload proof mechanism), and in the fourth stage, it switches to POS (equity proof mechanism)
on July 30, 2015, the first phase "frontier" of Ethereum was officially released. This phase is only suitable for developers. Developers can write smart contracts and decentralized application DAPP on Ethereum network, and miners begin to enter Ethereum network to maintain network security and get Ethereum coins. The leading-edge version is similar to the beta version, proving whether the Ethereum network is reliable or not
on March 14, 2016, Ethereum entered the second stage of "homeland". In this stage, Ethereum provides the wallet function, so that ordinary users can easily experience and use Ethereum. There is no obvious technology improvement in other aspects, but it shows that Ethereum network can run smoothly
in September 2017, Ethereum has reached the third stage of "metropolis"“ "Metropolis" is composed of Byzantine and Constantinople. The goal of this stage is to introce the hybrid chain mode of POW and POS, so as to prepare for the smooth transition from POW to POS. This is the latest popular "Ethereum Constantinople upgrade". In the Constantinople upgrade, Ethereum will make some changes to the underlying protocols and algorithms to lay a good foundation for the implementation of POW and
POS
how much reward will Ethereum get for mining? Miners who win the block creation competition will get the following income:
1. Static reward, 5 ethereums
2. The fuel cost in the block, i.e. gas, we talked about in the last issue
3. As a part of the block, it includes the extra reward of "Uncle block". Uncle is uncle of uncle, and each uncle block can get 1 / 32 of the mining reward as a reward, that is, 5 times 1 / 32, which is equal to 0.15625 ethereums. Here, let's briefly explain the concept of "TERT block". The concept of "TERT block" was proposed by Ethereum. Why should we introce the concept of TERT block? This also starts with bitcoin. In the bitcoin protocol, the longest chain is considered absolutely correct. If a block is not part of the longest chain, it is called a "orphan block". An isolated block is a block, which is also legal, but it may be found later, or the network transmission is slower, and it does not become part of the longest chain. In bitcoin, the solitude is meaningless and will be discarded later, and the miners who find the solitude will not receive mining related rewards
however, Ethereum does not think that isolated blocks are worthless, and Ethereum system will give rewards to miners who find isolated blocks. In Ethereum, isolated blocks are called "Uncle blocks", which can contribute to the security of the main chain. Ethereum's ten second block interval is too fast, which will rece the security. By encouraging the use of tertiary blocks, the main chain can obtain more security guarantees (because the isolated block itself is legal). Moreover, paying the tertiary block can also stimulate the miners to actively mine and actively use tertiary blocks. Therefore, Ethereum thinks that it is valuable.
First of all, we need to understand what is MLM:
MLM refers to the illegal behavior of organizers and development personnel to obtain wealth by calculating and paying remuneration to the developed personnel based on the number or performance of the personnel directly or indirectly developed, or requiring the developed personnel to pay certain fees to obtain the qualification to join. The essence of MLM is "Ponzi scheme", that is to say, the money of later comers is distributed to the income of former comers
However, the new type of MLM does not restrict personal freedom, does not accept ID cards and mobile phones, and does not take classes collectively. Instead, it uses capital operation as a banner to pull people to cheat money, drives luxury cars, wears gold and silver, and uses money to attract your relatives and friends to join in, and finally makes you lose all your moneythen judge whether the ether coin is a kind of MLM, whether you need membership fee, whether you need to ask your relatives and friends to join
extended materials:
Ethereum is an underlying technology platform on which developers can create distributed applications. With the application, there will be transactions. With a transaction, you need money to complete the transaction. In this way, money has value, and investors' investment has a return. If the transaction volume on the platform is larger and larger, the demand for money will be higher and higher, and the money will be more and more valuable
from the perspective of image, bitcoin creates a kind of digital gold, while Ethereum creates a country, and Ethereum is the credit currency of the country
after bitcoin, there are thousands of digital virtual currencies in the world, many of which are completely deceptive in the guise of "digital currency". Previously, Haikou Municipal Public Security cracked down on a pyramid selling organization called "Eurasian currency", which operated on the internet pyramid selling platform, making more than 40000 investors cheated, involving 4.06 billion yuan. The field of virtual currency has just started, so we need to be cautious

blockchain is an important concept of bitcoin, which is essentially a decentralized database and serves as the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
blockchain is public on the network and can be queried in every offline bitcoin wallet data. The function of bitcoin wallet depends on the confirmation with the blockchain. An effective inspection is called a confirmation. Usually, a transaction needs to obtain several confirmations. The lightweight bitcoin wallet uses online confirmation, that is, it will not download the blockchain data to the device storage
many of bitcoin's competitors also use the same design, but the workload proof and algorithm are slightly different. For example, the use of proof of interest and scrypt and so on
in addition, digital cryptocurrencies such as Laite coin, Ethereum, Weimeng coin, doggy coin and Ruitai coin also use blockchain technology.
mahjong is the earliest application of blockchain in China:
the idea that a wants to play mahjong is equivalent to creating a block:
a calls to inform B, C and D, which means "decentralization & quot; Point to point transmission of
ABCD has formed a consensus that the touch action is "mining", and four people are "miners"
mahjong is a hash value. The Hu card is to hit the correct hash value and get the corresponding chip reward, which is called bitcoin
each of the four recorded the first round of the game. In the whole blockchain, this is only one node. If 20 mahjong games were played that day, that is, 20 nodes (blocks), and 20 blocks were connected together to form a complete ledger, that is blockchain< According to historical records, China is the world's earliest application group in blockchain, so you can be proud to say that China is more than 1000 years ahead of the world in blockchain application
it's powerful. Our country is [strong] [strong] [strong]
to put it simply: if you are only the holder of eth, you don't need to make any preparation for this upgrade.
short video platform that I can earn money is not enough. I am going to share with you today a short video platform called tubing, jitter and block chain. Tiktok Kwai br />1, platform features are now short video platform, so many people finally won the jitter, and no quick response. But if a new short video platform wants to promote and get more traffic, it is bound to invest an initial capital to guide and support the content procers on the platform. Although we can't guarantee that this platform will continue, for us, even a novice who has just contacted the Internet, we can earn the first money from these short video platforms by moving. Is it worthless for us to release so many gimmicks on this platform? Of course not. In the field of blockchain, there is a concept called "decentralization". This concept is reflected in the community convention of short video of firebull, which has become such a paragraph: "firebull video community users are completely autonomous, without official management and audit, and are completely maintained through the user's behavior and community standards." Of course, there can't be a completely unregulated platform right now. But we can feel from this concept that the audit of this platform will be more relaxed than that of some old platforms. And with the addition of the concept of blockchain, users' behaviors on this platform, including watching, liking and commenting, are no longer just a simple number. These behaviors can directly increase the income of video owners. 2. Access to software firebull video is now online in the Android App store, but users on the IOS side can't find it in the Apple App Store yet. They can only download it by scanning the code. You can scan the following QR code to download and register
firebull video app to download: firebull video
however, the app downloaded by Apple mobile phone through scanning code will encounter the same problem as above, and the solution to this problem is extremely simple
IOS users first enter the settings interface, then click general, and then find the option of "device management"
in this option, we choose to trust the app, and then we can use the proct on Apple's mobile phone
after logging into this interface, we can start to register the account of firebull video
a new invitation code is required to register on firebull video, because the platform has a new policy. Here is an invitation code for you to fill in: 7960308
on the main page of short video, we can see that firebull video will directly provide a revenue channel for video owners through the function of "like". Users can praise the short video and then directly reward the video host with 10 virtual currencies. However, this reward will be different from that of other we media platforms, because all the virtual money spent in this reward behavior is provided by the platform, rather than the virtual money obtained after users recharge and purchase. This means that the content procers of this platform directly get the pink of the platform revenue, rather than waiting for the users to pay for it. It is precisely because users can conct a kind of free reward behavior, as long as the video can attract the attention of users, we have a great chance to obtain revenue. 3. User income because it is a short video platform related to blockchain, huoniu short video also adds the function of mining
on this platform, each user can get the virtual currency provided by the platform through the app. And from the above figure, we can see that as long as we watch and reward videos, we have a chance to get more platform virtual coins. This is the welfare period policy of the new platform, which means that the platform will not only encourage content procers to create content on the platform, but also encourage users to conct "user behavior" on the platform. Under this al stimulation, both content procers and users can guide more traffic for the platform. It is also this kind of welfare policy that both new and experienced people have the al means to obtain benefits. If we operate the platform as a user, there are only two ways to obtain virtual currency: one is to conct user behavior and watch, share and reward videos. As we can see in the above figure, there are 10 signs like small fire buffalo in the reward function. Users will consume a small fire bull by clicking reward, and each small fire bull will increase the probability of procing virtual currency. When we've consumed all 10 buffaloes, we'll get one for every 5 minutes we watch the video. In order to encourage users to watch and reward. Firebull video app Download: firebull video
the second method is to get virtual currency of platform reward through innovation. Because the platform is in an initial stage, it needs a lot of traffic support, so the platform will also have more support for pull new. Every time you pull a friend, you will get 80 virtual coins provided by the platform, and new users must fill in the invitation code when they register
you can fill in: 7960308
and we need to use Ethereum wallet to withdraw the virtual currency on the firebull video. Although the process will be complicated, with the trust endorsement of Ethereum, it is a cash withdrawal guarantee for users. However, this currency has not been online yet, so it can not be directly converted into RMB. 4. Dividend income
compared with the platform virtual currency that can't directly connect with RMB, I recommend you to directly become content procers to obtain income. For content procers, the platform will first calculate the virtual currency we get on the day of our short video, and then the platform will take out 80% of the revenue on the day, and give us dividends according to the proportion of virtual currency we get. And the dividend is directly in the form of cash dividends to our account, and is settled by the day. That is easier than pulling new harvest virtual currency or moving bricks to get dividend income
in this new platform, it is definitely the best that we can create our own content. If we can't create our own content, we can use this technology to find content that can attract a large number of users on other short video platforms, and then transport these content to the platform of firebull. If we want to avoid the homogenization of moving content, the users who have started the YouTube brick moving project can directly put their prepared videos on this platform. Of course, if some friends rely on their own wool traffic to operate the above mentioned pull new project, then we can also guide this batch of traffic to operate for our own video users, so as to increase our dividend income. However, whether it is to pull new or rely on traffic to improve our video dividends, we should try not to use technology tools to decode and brush. Because the benefits offered by the new platform are relatively high, if we use scientific and technological tools for batch operation, it is easy to be monitored by the platform because of high profits. Once it is found that cheating is used, we will be banned by the platform. Generally speaking, this is a project worthy of our operation. Although we can't ensure that this platform can continue to develop, we can also make a good profit in the welfare period of several months as long as we operate it properly.
