Block chain of parent currency

1. digital currency is an application of blockchain
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
taking the tourism instry as an example, blockchain applications mainly focus on tourism travel, tourism community reviews, digital identity management, credit consumption management, tracking pilot's professional certificate and qualification, loyalty plan of hotels and airlines, reservation management and consumption points management. In addition, blockchain also has applications in finance, games, entertainment and other fields.

2. The first category is currency projects, which are also the earliest blockchain projects. Currency projects mainly include bitcoin and lightcoin
in addition, there is another kind of asset with the characteristics of anonymity. Its main functions include protecting the privacy of both sides of payment while realizing payment. The more famous ones are dash, monero and zcash
currency is mainly used as the "exchange medium" in the field of blockchain assets. The exchange medium is the general equivalent you use to exchange goods. For example, gold, silver and silver bills can be used as the exchange medium in the past
at present, there are more than 1000 types of digital assets in the world, and the number of currency blockchain projects is not growing fast. As of January 2018, bitcoin is still the largest market value. We are already familiar with bitcoin. In the next few episodes, we will give a detailed introction to Leyte coin, Xinjing coin, Dasch coin, Monroe coin and zcash.

3. 1. Bitcoin
it is the birthplace of blockchain technology, and the market has confidence in it. It still maintains a stable growth under the adverse situation of major policies. Once it solves the problem of capacity expansion, the price rise can be predicted
2. Ethereum
compared with bitcoin, the advantage of Ethereum is that it has no policy problems. Although the event led to its bifurcation, the establishment of enterprise version Ethereum alliance may solve this problem. Its concept and Prospect of smart contract attract many developers to follow
the essence of community operation is that the majority decides the minority when indivials support eth
3. Zec
compared with bitcoin and Ethereum, the risk of z-coin will be greater, and its value will take a longer time to reflect. But in the long run, the value of anonymity will be one of the values that human beings generally pursue
4. BTS
bitstocks are very powerful and the system is very stable. Decentralized trading, anchoring system and so on. Although the founder bm's brain damage has hurt the community, the value of bitstocks is obviously undervalued. It is a wise choice to hold bitstocks on the cheap.

4. The development of blockchain technology is obvious to all, but there are essential differences between blockchain coin and virtual coin. It can be considered that blockchain projects developed with entity pain points have specific landing applications and entity support, and blockchain tokens issued with entity pain points still have certain value support; If there is no specific entity and application to support virtual currency, it is just air currency and has no value, then the risk is relatively large.

5. Virtual currency is a kind of blockchain technology. Some countries are legal, such as Japan, Russia, South Korea, etc. 66otc is currently the most fluent, reliable and best used OTC platform

6. There are not too many reliable domestic digital currencies. Generally, most excellent digital currencies are imported procts, such as bitcoin, Leyte currency, ether currency, etc
however, Yuanbao coin, Ruitai coin, bitcoin and the tokens of different crowdfunding projects in Europe are excellent digital currencies.

7.

I haven't heard of the saying "the sub currency of virtual currency". I don't know if you are talking about the bifurcation of virtual currency. For example, Ethereum and ethereal classics, bitcoin and bitcoin cash, etc. (if you want to know more, you can go to coin easy to have a look), is that what you mean

bifurcation refers to the community's disagreement when the blockchain network is "upgraded", which leads to the blockchain system being divided into two and the emergence of two different blockchains, as shown in the figure below

naturally, a new token appears in the new blockchain, which is what we call bifurcation coin. For example, in July 2017, in order to solve the congestion problem of bitcoin blockchain, several different solutions were proposed, which led to the bitcoin blockchain split in two and formed a new currency BCH (bitcash)

to some extent, BCH is the child of bitcoin, because it was born from the original system of bitcoin

In addition, bifurcations can be divided into "hard bifurcations" and "soft bifurcations", or take bitcoin as an example:

1. Hard bifurcations refer to the fact that the old node refuses to accept the blocks created by the new node when the bitcoin code changes. The blocks that do not conform to the original rules will be ignored, and the miners will create new blocks after the blocks they finally verify according to the original rules

2, Soft bifurcation can be compatible both backward and forward

although blockchain forking will not split your currency in two, it may also proce a new currency on the basis of the original, but blockchain forking is not good news most of the time, because it represents great differences in the community

of course, not all blockchains will have forks, and most of the forked currencies appear in digital currencies adopting POW consensus mechanism

8. 1. The value of bitcoin does not lie in its computing method and encryption algorithm. 2. The calculation and proction of bitcoin need time, equipment loss and electricity cost. 3. The total output of the algorithm is limited. 4. Some foreign and domestic objects have supported bitcoin payment, which makes it have the preliminary property of currency. 5. There is no difference between bitcoin and the legal currency of any country in its own value. A piece of printed paper or PVC does not have actual value. It can not have the characteristics of rare metals like gold. 6. The biggest risk of bitcoin is that no country, bank, military or government can guarantee its credibility. 7. At present, it seems to be just a virtual currency with speculation value. 8. Its circulation value is certainly not as popular as q-coin in China. For example, few people in second tier cities know about bitcoin, let alone let it admit its value.

9. Blockchain is the underlying technology of bitcoin. Blockchain and bitcoin complement each other.
