Block chain stock selection formula

1. In short, the data of the blockchain is formally stored in the blockchain through the formula algorithm process of the block. All nodes in the whole network express that they accept the block, and the way to express acceptance is to make the random hash value of the block the latest block hash value. Xingqun manufacturing will be extended based on the blockchain.

In 2009, bencong invented bitcoin, and set that there are only 21 million bitcoins. By participating in the proction of blocks and providing proof of work (POW), he can get the reward of bitcoin network. This process is mining

the concept of "mining" comes from the existing concepts in our real economic life, such as gold mining and silver mining. Because minerals are valuable, it drives people to pay labor to dig

another important point of bitcoin mining is that the miners who participate in mining recognize the value of bitcoin, and some of them are willing to spend money in the bitcoin market. Therefore, the mining of bitcoin is meaningful

currency characteristics of bitcoin

1, decentralized

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

2, 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

controlling bitcoin requires a private key, 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 in the end, about 1 bitfen transaction fee 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

Blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects

on January 10, 2019, the state Internet Information Office issued the regulations on the management of blockchain information services. In October 24, 2019, ring the eighteenth collective learning of the Central Political Bureau, general secretary Xi Jinping stressed that "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". "Blockchain" has entered the public field of vision and become the focus of social attention

on December 2, 2019, the word was selected into the top ten catchwords of "biting words" in 2019

Application of blockchain Finance:

since 2016, the major financial giants have also carried out blockchain innovation projects to explore the possibility of applying blockchain Technology in various financial scenarios. In particular, Puyin group took the lead in creating a "blockchain +" standard digital currency

standard digital currency refers to the process of assets identification, evaluation, right confirmation and insurance completed by a third party organization, which is written into the blockchain through careful digital algorithm to form the standard corresponding relationship between assets and digital currency, which is called standard digital currency

in order to realize the great leap forward development of blockchain finance, promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that has been struggling for generations, Puyin group will hold the Guiyang strategic development ceremony of Puyin blockchain finance in Guizhou on December 9, 2016

the meeting will discuss the realization of digital circulation of assets by blockchain, the financial transaction mode of blockchain, and the application of blockchain services and social public instry. This conference will mark the beginning of the application of blockchain finance and the change and development of the new financial ecology

In recent years, blockchain and artificial intelligence have been very popular

first of all, blockchain is to establish a decentralized network. The so-called decentralization means that the network does not belong to you or me

it belongs to everyone

Artificial intelligence is a new technology science that researches and develops the theory, method, technology and application system for simulating, extending and expanding human intelligence. In other words, "machine self-learning"

in this way, we can think about the combination of blockchain and artificial intelligence

first of all, we need to understand that blockchain can be divided into three stages

However, in the first three stages, there are some problems, such as the lack of decentralization, low scalability, the mismatching between the incentive of the blocker and the best profit of the whole network, and the network always running at the maximum capacity. Serious waste of resources and rece efficiency

so can we combine artificial intelligence with underlying public chain technology to solve these problems

The answer is yes! And there has been team research and development, and has made a certain progress

Velas is a public chain that enhances its consensus algorithm through artificial intelligence (AI) optimized neural network, and carries out self-learning and self optimization. It is committed to improving the security, interoperability and high scalability of the transfer process and intelligent contract. Velas adopts the dpos consensus enhanced by AI, which completely realizes decentralization without recing the security and transaction speed. Not only that, AI chooses who to mortgage the token according to the needs of the blockchain; Velas only blocks when needed; Every 1 second to every 2 minutes; Scalability (up to 30000 TPS); Block procers are selected by artificial intuition

5. The reason why blockchain is deceiving is that many funds and air coins are under the banner of blockchain to recruit people to "cut leeks" to cheat money. Therefore, if you want to make investment, you should be careful of this. If you just want to know, I will some information I found to you. The following content comes from the network and my personal opinions, so it is only for your reference< The br / > Bobbi block is actually a panoramic life service application of block chaining, which applies block chain's underlying technology, artificial intelligence technology and panoramic VR space technology to build block chain ecosystem. It can be used for personal safety wallet tools (aggregating UnionPay, Alipay, WeChat payment, PayPal, and bank card payment). You can also set conditions for the other party to receive
for enterprises or groups, they can make use of the Bobbi panoramic blockchain as an intelligent ERP management system, put the enterprise's information and services into the panoramic space, and display their blockchain encrypted procts in the panoramic block. They can also establish their own blockchain distribution system through the intelligent contract, so as to truly realize the integrated operation of proct promotion and drainage, user experience and authentic proct sales
let's talk about my personal opinion. In recent years, blockchain has a trend of combining with different popular technologies, such as AI + blockchain, AI + blockchain and so on. This blockchain is panoramic technology + blockchain, so it is also an innovation to comply with the trend. Anyway, it seems that the concept of panoramic + blockchain is their idea, You can see the proct application or landing project corresponding to their concept. If the concept and proct application do not match, it is a gimmick. If not, it is not a fraud blockchain. The rest depends on your own understanding and judgment
very attentive answer, if you think it is helpful, please take it, thank you!

As for this question, I suggest you go to lobby the community to have a look (web link), where there are big guys and big V to answer for you. Here I share with you an article by Mr. Ruan Yifeng, which should be able to answer your questions

I. what is the essence of blockchain? In a word, it is a special distributed database

the current rule is that new nodes always use the longest blockchain. If there is a fork in the blockchain, we will see which branch is behind the fork point and reach six new blocks first (called & quot; Six confirmations. According to the calculation of a block in 10 minutes, it can be confirmed in one hour

since the generation speed of new blocks is determined by computing power, this rule means that the branch with most computing power is the authentic blockchain

9. As an unmanaged distributed database, blockchain has been running for 8 years since 2009, and there is no big problem. This proves that it is feasible

However, in order to ensure the reliability of data, blockchain has its own costs. One is efficiency. When data is written to the blockchain, it takes at least ten minutes. If all nodes synchronize data, it takes more time; The second is energy consumption. The generation of blocks requires countless meaningless calculations by miners, which is very energy consuming

therefore, the application scenarios of blockchain are very limited

there is no management authority trusted by all members

the data written by

does not require real-time use of

the benefits of mining can make up for its own costs

if the above conditions cannot be met, then the traditional database is a better solution

at present, the biggest application scenario (and possibly the only one) of blockchain is cryptocurrency represented by bitcoin

About dragonex dragon token

1, basic introction

Dragon token (DT) is a token issued by dragonex based on Ethereum erc20 standard, and each dragon token stored on the platform has the right of project dividend

every day, the transaction commission income of dragonex project will be distributed to all dragon coin holders according to the holding proportion of dragon coin

2. Mining method

longcoin can not be obtained through ICO or pre excavation

all dragon coins can only be generated in the form of "mining", and the only way of mining is to trade on the platform“ Miners (i.e. platform users) contribute to the platform through trading behavior, and the platform issues dragon coins to miners as rewards

the total number of dragon coins issued was 37339500, and promised never to be issued

3. Release rules of dragon coin

Dragon coin is a token based on Ethereum smart contract. Since the launch of Genesis, the smart contract will be released for a total of 3650 times, with an interval of 24 hours and a cycle of 365 times

in the first cycle, 51200 dragon coins will be released each time; The yield of each cycle will be 50% lower than that of the previous cycle

4. Longcoin distribution mechanism

the platform will make statistics on the mining situation of "miners" every day, and the statistical cycle is 0:00:00-23:59:59 on that day; Each time the smart contract releases the Dragon coin, the platform will allocate the new dragon coin to the corresponding "miner" account on the next day according to the statistical data

"miners" dig out dragon coins through trading behavior, but the excavated dragon coins are not 100% owned by miners, among which:

① "miners" get 30% dragon coin reward and

② market brokers get 20% dragon coin reward Market broker: if miner a uses the invitation link of user B when registering, then B is the market broker of user a)

③ dragonex project party gets 10% block dragon coin Award (frozen for one year: for project marketing)

(4) dragonex project party gets 40% block longcoin Award (permanently frozen: used for platform technology research and development, talent introction, project operation, buy back longcoin and destroy)

note: Singapore standard time (UTC / GMT + 08:00)

5. Longcoin dividend mechanism:

① 100% of the daily platform revenue will be distributed to longcoin holders according to the proportion of longcoin holdings

② the platform will take a snapshot of the balance of dragon coin holders at 23:59:59 every day. Since the Dragon coin g up on the same day will arrive the next day, the user can share the Dragon coin on the same day = snapshot data + dragon coin g up on the same day. Dividends will be paid the next day, in the form of usdt to each holder's account

③ dividend formula:

project party's income to be paid dividends = transaction fees + other income of the project

dividend income of currency holding users =

income to be paid dividends * [number of indivial dragon coins held / (number of issued dragon coins - number of destroyed dragon coins)]

6. Online time of dragon coins

Dragon coins began to "mine" and calculate dividends from November 2, 2017

e to the fact that Longyuan is still in the development stage, it can not be released to miners and market brokers. However, the project side will record the data of everyone, and after the development of longcoin is completed, the longcoin and dividends e to everyone will be distributed to the account

longcoin is expected to be developed before November 25, 2017, and will be traded online on dragonex platform. The specific online transaction time will be subject to the official announcement later
