Blockchain Hasi coin

1. digital currency is an application of blockchain
blockchain is a new computing paradigm and distributed infrastructure, which uses fast chain data structure, distributed node consensus algorithm, cryptography and intelligent contract based on automated script code to proce, verify, store and transmit data. It can also be said that blockchain is a distributed ledger technology, which can provide decentralized trust mechanism in non trust environment, so that multi-party participants can conct secure trust transactions without intermediaries
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.

2. Blockchain is an emerging instry, which has been highly valued by all countries. It is called the fourth instrial revolution and will have an immeasurable impact on society. Blockchain is the literal translation of block and chain. Each block stores the transaction data within a specified time, and forms a non tamperable, all staff shared distributed ledger through cryptography
digital currency and virtual currency are actually different names. They are tokens issued based on blockchain technology. Behind them are a series of computer-generated complex codes. At present, there are thousands of digital currencies in the market. The safest and most powerful digital currency is bitcoin
digital currency is also a high-risk and high return investment proct, through appropriate investment strategies, you can get rich returns. If you have spare money, you might as well put some of it into the digital currency. There will be unexpected surprises.

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. Laikelib blockchain infrastructure operation team thinks: blockchain technology can be understood as a public accounting mechanism, which is more a technical solution than a specific proct. The basic idea is to establish a set of public account books on the Internet, in which all users in the network keep accounts and check accounts together, so as to ensure the authenticity and non tamperability of information. The reason why it is called "blockchain" is that the structure of blockchain storage data is composed of a chain of "storage blocks" on the network. Each block contains all the information exchange data in the network within a certain period of time, and the chain continues to grow over time
relationship between blockchain and bitcoin: bitcoin used to be one of the most successful applications of blockchain technology. Specifically, the blockchain is a series of data blocks generated by the use of cryptography Association, and each data block contains the information of effective confirmation of multiple bitcoin network transactions. It can be said that bitcoin is a "killer application" of blockchain idea. Blockchain is the underlying technology of bitcoin, but its role is not limited to bitcoin.

7.

Often when we talk about value, we will naturally relate to price. Indeed, price is an important data to measure value. As a blockchain technology, bitcoin's price reached 140000 RMB when it was high, and now it has dropped by about 50%, but it is still as high as 80000 RMB

At this point, you may have understood: if people do not have a common understanding of a thing, and do not give value to a thing, many things will not become "valuable". Just like our understanding of air and food, it is necessary for us to live and survive! This is the "consensus". We all believe that if we want to live, these two are indispensable! Therefore, we can conclude that the essence of value is consensus. What is the value consensus of virtual currency? Most people think that the essence of currency is not consensus, but the credibility and authority of the ruling government. This is not unreasonable. The government can only be one of the sources of value consensus, so most people think it is not comprehensive. In today's society, our consensus on the value of things comes from many ways, such as: Endorsement of authoritative institutions, corporate credit, religious belief, support of scientific theory

8. Litecoin litecoin (LTC), released on October 7, 2011, is currently the most valuable counterfeit coin, accounting for about 2% of BTC's market value. The current unit price is US $2.31, with a total currency value of US $38 million. It's also a distributed (decentralized) digital currency. Unlike the sha256 mining algorithm used by bitcoin, LTC adopts scrypt algorithm. Scrypt algorithm uses sha256 as its subroutine, and scrypt itself needs a lot of memory. Each hash is used as the seed of the input, and then it needs a lot of memory to store another pseudo-random sequence to generate the pseudo-random points of the sequence and output the hash value. In the mining of BTC (bitcoin), it is not enough to rely on simple graphics card mining (it takes about ten to dozens of days to dig a BTC with general configuration graphics card). The emergence of various expensive mining machines has raised the threshold for ordinary people to get BTC through mining, while LTC has certain advantages in using PC graphics card mining This passage comes from Zhihu.) Compared with BTC, litecoin has made a little improvement in technology. If BTC is gold now, LTC is silver for the time being. The biggest advantage of litecoin is that it can confirm the authenticity faster. The virtual currency is designed and maintained by Charles Lee. Bitcoin transactions need to be verified, and the average verification time is more than 10 minutes. Most transaction websites need 1 hour to verify. The average transaction confirmation time of liteoin is 2.5 minutes. Developers claim that shortening the verification time increases the practicability of virtual currency. The bitcoin mining efficiency of customized machine and amdgpu is the highest, making it almost unprofitable for miners using CPU mining. Litecain's mining excludes GPUs and custom processors, so it doesn't rely too much on a small number of professional miners. Ppcoinppcoin (PPC) was released on August 19, 2012, which has improved the original technology of BTC. Use proof of stack and join the concept of coinage. Ppcoin is a bifurcated project of bitcoin, which aims to achieve energy efficiency and keep the best performance of the original bitcoin as far as possible. The unit price of ppcoin is US $0.22 and the total currency value is US $4 million. Ppcoin does not have a fixed upper limit of money supply, but it does not mean that ppcoin has obvious inflation compared with bitcoin. Bitcoin can be compared to gold. The annual inflation rate of gold is about 1-3%. Although gold has no known upper limit of money supply, we still know that it is a reliable scarce commodity. There are two types of ppcoin casting: work certificate and equity certificate. The coinage rate of working proof is affected by Moore's law, which depends on the doubling of our working proof ability. What we all know is that Moore's law will eventually come to an end. By then, the ppcoin of inflation may be close to the gold level. The annual maximum inflation rate of certificate of equity is 1%. At the same time, ppcoin's transaction costs were destroyed to fight inflation. So on the whole, the coin design of ppcoin is still a very low inflation design in the future, which can be comparable with bitcoin. Ppcoin is awarded in a lottery like way, and the winning probability is determined by the number of ppcoins held by miners, said sunny king, one of the founders. Their design is based on a new concept of long-term energy efficiency. Terracoin terracoin (TRC) was released on October 26, 2012, with a total currency of 42 million. The speed of each block is 2 minutes, slightly faster than LTC. There is not much special in technology, similar to the proction of BTC halved every four years. However, the operation team seems to have a strong business background and may be better than other bitcoin in circulation. The development of virtual currency is getting more and more attention. Now some teams with business background will accelerate the development of virtual currency. Namecoin namecoin is a distributed domain name system based on bitcoin technology. Its principle is the same as bitcoin. This open source software was first released on April 18, 2011. Namecoin is generated from an original block which is different from bitcoin's main trading block. It uses a new blockchain, which is independent of bitcoin's blockchain. Because it is based on bitcoin, the security, distribution, robustness, encryption and migration of domain names are mathematically guaranteed. You can dig bitcoin and namecoin at the same time. This project was discussed and proposed by bitdns, which is mainly dissatisfied with the defects of DNS. The only top-level domain name of namecoin is. Bit. It costs namecoin to register a. Bit domain name.
