Is BVB virtual currency a public chain
1、 Different definitions:
1. virtual currency:
virtual currency refers to non real currency
digital currency:digital currency is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
3. Cryptocurrency:
cryptocurrency is a kind of transaction medium that uses cryptography principles to ensure transaction security and control the creation of transaction units
4. Token (token):
a kind of article whose shape and size are similar to currency, but the scope of use is limited and has no currency effect, and its token is the homonym of token in English
Second, the characteristics are different:1; It can also be said that virtual currency is personalized currency. In another way, it can also be called information currency
2. Digital currency:
is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities
Cryptocurrency:cryptocurrency is based on the decentralized consensus mechanism, which is opposite to the banking and financial system relying on the centralized regulatory system
4. Token (token):
usually needs to be exchanged for money, used in shops, playgrounds, mass transportation and other places, as a voucher to use services and exchange goods
extended data
at present, digital currency is more like an investment proct, because it lacks a strong guarantee agency to maintain its price stability, and its role as a value measure has not yet appeared, so it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investment company
digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stability
Public chain, also known as "public chain", refers to the blockchain that anyone in the world can enter the system at any time to read data, send confirmatory transactions and compete for bookkeeping. The public chain is generally considered to be "completely decentralized", because no indivial or institution can control or tamper with the reading and writing of data in it. In terms of application, blockchain public chain mainly includes bitcoin, Ethereum, super ledger, most counterfeit currencies and smart contracts. The ancestor of blockchain public chain is bitcoin blockchain, which has the following characteristics:
1, open source code
upload the code to GitHub, and everyone can get complete blockchain data by downloading, Accept the test of the public
2, complete decentralization
anyone can become a node, each node is open, everyone can participate in the calculation of the blockchain, any node is not permanent, but phased, and any center is not mandatory for nodes. Anyone can read and send transactions, and transactions can be effectively confirmed on the blockchain. Anyone can participate in the consensus process. The consensus process determines whether a block can be added to the blockchain and the exact current state. Everyone can get financial reward from it, which is proportional to their contribution to the consensus process. These public chains are generally considered to be "completely decentralized"
3. Developing decentralized applications
through this public chain, developers can easily develop centralized applications. Public chain can protect the rights and interests of users from the influence of program developers
This is two different concepts. According to different standards, blockchain can be classified into three categories:
& # 8195&# 8195; 1) According to the network scope of blockchain, it can be divided into public chain, private chain and alliance chain
&# 8195; 2) According to the docking type of blockchain, it is divided into single chain, side chain and interconnection chain
&# 8195; 3) According to the display environment of blockchain deployment, it can be divided into main chain and test chain
the main chain can be understood as a formal online and independent blockchain network, while the public chain refers to a blockchain that can be read by anyone, can send transactions and can be effectively confirmed by anyone, and can participate in its consensus process
virtual currencies are generally at the bottom, and many of them are pyramid schemes or funds
in fact, cryptocurrency, virtual currency and digital currency are the same, but they are called differently
at present, the mainstream digital currencies in the market include bitcoin, bitcoin cash, wikilink and so on.
Public chain is also known as "public chain", and public chain refers to the blockchain that anyone in the world can read and send transactions, and transactions can be effectively confirmed, and can also participate in the consensus process. According to the different degree of blockchain network centralization, three kinds of blockchain under different application scenarios are differentiated:
1. The blockchain with open whole network and no user authorization mechanism is called public chain
2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain
3. All the nodes in the network are in the hands of one organization, which is called private chain
extended data:
function of public chain:
1. Public chain can protect users' rights and interests from the influence of program developers:
in public chain, program developers have no right to interfere with users, so public chain can protect users' rights and interests using the program. In addition, the highly decentralized distributed data storage is also one of the biggest characteristics of the public chain, which has the advantages of openness and transparency of transaction data, and data can not be tampered with, so that the public chain can effectively protect the data security of users
2. Public chain can proce network effect:
an information proct has the inherent need of interconnection, because the purpose of people procing and using them is to better collect and exchange information. With the expansion of the network scale, users can get more value from it and their needs can be met. The common chain is open, so it has the opportunity to be applied by many external users and proce a certain degree of network effect
3. Public chain can be applied to actual business scenarios:
except for financial applications, any application scenario with high requirements for trust, security and persistence, such as asset registration, voting, management and Internet of things, will be affected by public chain on a large scale
source: network public chain
at the same time, it can provide mutual trust for transactions by using trusted self-executive code, so as to rece uncertainty and promote digital transfer and asset transactions
bitcoin is the most well-known blockchain as an encryption currency that uses blockchain technology to realize alternative payment. Bitcoin is a kind of unlicensed blockchain, also known as public blockchain, which does not restrict the identity of users who consume bitcoin or participate in verifying the authenticity of transfer blocks in the blockchain (an energy intensive process, also known as "mining"). These miners get token, or bitcoin, in return, and given that everyone can view the block (though anonymously), the blockchain itself is somewhat transparent
bitcoin is controversial and banned by many countries e to user anonymity to a large extent. However, it is worth noting that the anonymity and energy use of bitcoin are its own characteristics, not the characteristics of the whole blockchain technology.
The first is to increase the time limit. For example, as I said just now, our time limit is very short, just three days, and it's useless when it's expired
another way is to raise the threshold of things exchange, but this will make points a little weak
the second way is to increase the number of lucky draw and points to win treasure, and collect the scattered points by some means to benefit a small number of users. In fact, this is also a helpless move. Of course, if the design is good, it is also very interesting. Jingdou uses this method
the third way is to let points become the threshold, such as how many points + how much money you need to buy something, or what level of points you can buy. This is actually very good. It's quite clever to get goods through low price channels, sell procts at a price slightly lower than the market price but slightly higher than the cost price, and consume points at the same time. The premise is to have good goods and good channels
the fourth way is to exchange points for rights, such as membership privileges, lottery times, game times and so on. This practice is also OK. For example, if you exchange for a thunderbolt member, you can consume points and stick to users. The key is that these authorities can attract people or negotiate cooperation with these channels
how to establish a perfect integral system can be used for reference by the major e-commerce examples, which will not be discussed in detail here. With the system, the key is how to operate an e-commerce points system. E-commerce points are real money. If you want to operate money, you need to consider three dimensions
1, anti cheating
now there are two major trends in operating points - it's very difficult to earn and I don't want to play. Especially easy to earn, I don't want to play
especially easy to earn - there are loopholes in points that are easy to earn, negligence in human design, or insufficient anti cheating function
obtaining points by cheating will destroy the incentive system for users
2, reservoir
integral is a reservoir, through long-term accumulation, release at a certain time point, you can get the pleasure of release, and feel that the savings are useful
how to make good use of the reservoir, we need to set a warning line - more than how many points, we need to encourage users to exchange
how to make good use of the function of the reservoir, timely remind, timely consumption, timely exchange, more savings, more profits
how to make users fall in love with point incentive? Saving points is either to exchange valuable items, or to make users feel cheap at any time
How to rece the cost of incentive is the corefor example, to motivate a user to use 100 yuan (within the life cycle) to extend the user's life cycle and rece the incentive cost (to 50 yuan)
how to establish a powerful integral system is a science, not only a simple proct function, but also a simple operation means, It needs a lot of knowledge whether to play with points or not. In my opinion, this is a deep test of operation
