Virtual currency talk

1.

According to the current difficulty calculation, we can dig about 1.012 Laite coins a day. This is the average calculation result in the mine pool. If there is an efficient mine pool or solo, maybe more

litecoin (abbreviated as LTC, currency symbol: 321;) It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world

lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization. Lightcoin aims to improve bitcoin. Compared with bitcoin, lightcoin has three significant differences. First, the lightcoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the lightcoin network is expected to proce 84 million lightcoins, four times the amount of money issued by bitcoin network. Thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in lightcoin's workload proof algorithm, which makes it easier to mine lightcoin on ordinary computer than bitcoin. Each Leyte is divided into 100000000 smaller units, defined by eight decimal places

design purpose

it is based on bitcoin protocol, but it is different from bitcoin in that even at the present stage, it can efficiently "mine" through consumer hardware. Liteoin provides you with faster transaction confirmation (2.5 minutes on average). It uses hard memory and mining workload proof algorithm based on scrypt (an encryption algorithm). It is oriented to ordinary computer and graphics processor (GPU) used by most people. The litecain network is expected to proce 84 million currency units

one of the design purposes of litecoin is to provide a mining algorithm, which can be run simultaneously on the bitcoin mining machine. With the rise of application specific integrated circuits (ASIC) designed for bitcoin mining, litecoin is also closely following the technological evolution. But before the widespread use of litecoin currency, it is unlikely that there will be an application specific integrated circuit (ASIC) specially designed for litecoin

transactions

a peer-to-peer network similar to bitcoin handles lightcoin transactions, balances, and issues through a script workload proof scheme (when a sufficiently small hash value is found, the, A block will be created, and the lightcoin will be issued. The process of discovering the hash value and creating the block is called "mining"). The issuing rate of Leyte coins is reced by half every four years (every 840000 pieces) according to the proportional sequence, and finally the total number of LTCs is 84 million. Unlike bitcoin, the memory intensive feature of script makes it more suitable for "mining" with graphics processor (GPU). FPGA (field programmable gate array) and ASIC (application specific integrated circuit) implemented for script are more expensive than sha256 used for bitcoin

currently, lightcoin can exchange legal tender and bitcoin, most of which are through online trading platforms. Revocable transactions (such as credit card transactions) are generally not used to purchase Leyte, because Leyte transactions are irreversible, which brings the risk of refund. As of April 25, 2013, a Leyte is worth about $3.97 or 0.028 bitcoin. This makes Leyte the second largest electronic currency with a market value of about $35 million

litecain is a free software project released under MIT / X11 license, which allows you to run, modify and the software according to your own needs. You can also release a modified version of the software if you like

the software is released in a completely transparent form, and users can independently verify the binary version and the corresponding source code

mine pool

the lightcoin is generated by "miner's mining". Mining is done by hashing with computer graphics card. If the value of "mine burst" is calculated, the system will reward 50 lightcoins at one time. At present, the computing power of lightcoin is growing rapidly, and the miner can't find the mine through several computers. Therefore, it is necessary to join the mine pool, which collects all the computing power, It is estimated that the probability of calculating the "blasting" value is higher

at present, the well-known mine pools include BTCC (original bitcoin China) mine pool, waltc.net fish pool (f2pool), wemineltc, coinotron, silverfish, liteguardian, litecoin pool.org, etc. But at present, the highest income is f2pool. Recently, it launched lightcoin theory income + 10% of mine pool subsidy = your actual income, which has attracted the attention of many miners and the instry

data block chain

litecoin block chain, compared with its competitor bitcoin, can handle larger transaction volume. Due to the more frequent generation of data blocks, the network can support more transactions without modifying the software in the future
as a result, businesses can obtain faster transaction confirmation, and they can still wait for more transaction confirmation when they sell large value procts

In fact, digital virtual currency is far from the above. Forbes magazine listed the top 30 virtual currencies in the market by their total market value and price as of 10:00 a.m. local time on the 27th. Caijing.com and venture capital Post said that there are at least 60 kinds of virtual currencies currently traded According to the Forbes report, bitcoin ranked first in market value and unit price. It was the lightcoin designed by Li Qiwei, a former Google programmer, that won "erlianya". In the past week up to the 27th, the price of lightcoin rose rapidly from $6 to $26, a considerable increase. The third to fifth place in the total market value are spot money, nominal money and prime money. The report counted the 24-hour gains as of the 27th. Almost all of the 30 currencies rose, with the biggest increase of the quark currency, reaching 278.55%. The report also said that almost all virtual currencies have taken a ride in the current round of bitcoin's rise, but most of them have poor business, with 8 companies with a total market value of less than $1 million and 19 companies with a unit price of less than $1

Digital currency is an alternative currency in the form of electronic currency (which can be used for real goods and services transactions)

digital currency has the main characteristics of network packets. This kind of data packet is composed of data code and identification code. The data code is the content we need to transmit, while the identification code indicates where the data packet comes from and goes

based on the characteristics of digital currency, the direct benefit of digital currency to the central bank is not only to save the cost of note issuance, circulation and settlement, but also to enhance the central bank's ability to control funds

Electronic money and virtual money are called digital money. According to the definition of the European Central Bank, virtual money is issued by non central banks, credit institutions and e-money institutions, which can be used as the numerical expression of the value of currency substitutes in some cases

{rrrrrrr}

extended information:

the process of digital currency trading through the platform is as follows:

(1) investors should register accounts first, and obtain digital currency accounts and US dollar or other foreign exchange accounts at the same time

(2) users can buy and sell digital currency with the money in their cash account, just like buying and selling stocks and futures

(3) the trading platform will sort the buying requests and selling requests according to the rules and start to match them. If they meet the requirements, the transaction will be concluded

(4) e to the difference between the buy and sell volumes submitted by users, a buy or sell request may be partially executed

3. Here's a brief introction to several mainstream digital currencies to give you a rough idea. After that, I will talk about the specific currency from time to time

bitcoin is the originator of digital currency and the most valuable virtual currency. Because blackmail virus only takes bitcoin, it has entered the public view. The soaring price of bitcoin in 2017 has attracted a large number of investors to enter the digital money market. Because the number is small, it is only 21 million, which has a strong deflationary attribute
of course, I am extremely optimistic about the future of bitcoin. Of course, many people are not optimistic about digital currency. Here, it is most pertinent to quote Krugman's view:
"at least for now, buying bitcoin is still a good investment. But that doesn't mean the experiment was successful. The original intention of establishing a monetary system is not to make those who hold money rich, but to make transactions convenient and benefit the whole economy. And none of these bitcoins came to us. "
reborn currency
a protocol currency issued by reborn, which is the base currency of reborn network. It can circulate in the whole reborn network, with a total amount of 100 billion, and graally decreases with the increase of transactions. Reborn currency is the only common currency in ripple system, which is different from other currencies in ripple system, Ripple labs (formerly known as opencoin) is the operating company of ripple coin
unlike bitcoin, reborn is a kind of transaction protocol, which is called smart contract in technical terms. It supports people to pay in any currency, and does not need a central data exchange center, so the transaction confirmation time of ripple is only 35 seconds, while that of bitcoin is 10-40 minutes

Ethereum
Ethereum is the name of currency used in Ethereum, which is used for payment calculation in Ethereum virtual machine. Ethereum is a blockchain that can be used to deploy decentralized applications. It is an open source computer platform and blockchain platform. At the end of 2013, it was founded by vitalik buterin, a Russian programmer
there is a key difference between the blockchain technologies used by Ethereum and bitcoin. Ethereum's data processing speed is faster than that of bitcoin, because once agreed, Ethereum's system will automatically apply to the terms and conditions in the contract
unlike bitcoin, the value of Ethereum depends on whether the applications on the platform of Ethereum are prosperous or not, just like the price of oil will rise with more machines using oil

bitcoin cash
bitcoin cash is a branch of bitcoin. In order to solve the problem of long transaction time of bitcoin, at 20:20 on August 1, 2017, a small number of mining machines began to use 8m block to start mining, and the transaction confirmation speed was thousands of times faster than that of bitcoin using 1m block
strictly speaking, however, there are different opinions on whether this is a new branch of bitcoin or another kind of "counterfeit currency". But now the offer of bitcoin cash is nearly 20000 yuan, so it's not too much to use it as a kind of "Shanzhai coin" to divide bitcoin traffic

IDA coin, ADA in English, is a proct of Cardano project. The total amount of Aida is 4.5 billion yuan, and 3 billion yuan will participate in the subscription. Among them, 2.5 billion ADA will be used for platform subscription, 500 million for the financial support of the development company's operating company, and 1.5 billion ADA coins will continue to be issued in the form of block awards
Cardano is a project started in 2015 to change the way cryptocurrency is designed and developed. This project is aimed at technical reformers, technical improvements to bitcoin and existing platforms. If bitcoin, Ethereum and other projects have many other shortcomings, Cardano can solve them<

lightcoin
a currency based on bitcoin protocol, but it does not require very high computing power, and it can also be mined by ordinary computer. Lightcoin's algorithm comes from the algorithm designed by Dr Colin Percival for tarsnap secure online backup service (backup for Linux and other open source operating systems)
for a long time, there has been a voice that "lightcoin will replace bitcoin", which is impossible. In the future, there will probably be a variety of cryptography currencies in the world, but any kind of counterfeit currency can not replace the mainstream position of bitcoin, no matter how excellent its algorithm is compared with bitcoin<

stellar currency
stellar currency, a digital currency project initiated by Jed McCaleb, the former founder of ripple, is used to build a decentralized gateway between digital currency and legal tender. It will be provided to users in the form of free distribution, and its supply online is 100 billion, of which 95% of the amount of star coin is used for free distribution
star is a diversified team. The board members include Keith rabois, former COO of square, Patrick collison, CEO of stripe, Jackson Palmer, co-founder of dogcoin, and naval Ravikant, co-founder of angellist, who will be the consultant of the project< New economy movement, or NEM, was founded on January 19, 2014. The founder is a mysterious person in bitcointalk.org forum called utopianfuture. The original intention of utopian future was to build a second-generation digital currency NXT. He then realized that NXT's distribution model was unreasonable, so he devoted himself to NEM with egalitarian distribution
as a kind of cryptocurrency, new coin does not need much computing resources to maintain the operation of nodes. The proof of importance (POI) engine of NEM reces the threshold of computing resources to participate in non-traditional blockchain<

dascoin
formerly known as black coin, is a kind of counterfeit currency of bitcoin, which focuses on anonymous function. There are many innovations, such as master node network, fast payment, mixed currency anonymous technology, proposals can vote, and developers have fixed budget support. The core consists of a unique incentive P2P network. Miners are rewarded for maintaining blockchain security; The main node holders are rewarded for verifying transactions, storing data and providing a variety of services
the feature of anonymity meets the needs of some investors for absolute privacy. Although bitcoin is also widely used in money laundering and other illegal transactions e to its anonymity, it is only "pseudo anonymity", and the transaction of bitcoin can still be traced back to the traders themselves.

4. Hello, it's called EOS token. It's based on Ethereum token
EOS coin
EOS (Chinese Name: EOS, English Name: EOS, abbreviation: EOS) is a token based on Ethereum released for eos.io blockchain system. Blockone is a new blockchain architecture developed by blockone company, which aims to expand the performance of distributed applications. The goal of EOS project is to achieve a blockchain architecture similar to the operating system supporting applications. The architecture can provide account, identity authentication, database, asynchronous communication and program scheling on hundreds of CPUs or clusters. The ultimate form of this technology is a blockchain architecture, which can support millions of transactions per second, and ordinary users do not need to pay for the use of the blockchain
function of EOS token
the current form of EOS cryptocurrency belongs to ERC 20 smart contract token on Ethereum blockchain. EOS ERC 20 token will be converted into the cryptocurrency available in EOS system 1:1 after the formal launch of EOS blockchain. The EOS system is expected to release the test network in August 2017, and it is expected to take one year for the main network of EOS blockchain to go online. The following application scenarios are introced after the EOS blockchain is officially launched
EOS cryptography currency has three main application scenarios: bandwidth and log storage (hard disk); Calculation and calculation reserve (CPU); State memory (RAM)
both instantaneous and long-term components consume bandwidth and computation. The blockchain system will maintain logs of all messages, which will be downloaded and stored by all complete nodes. With log information, the state of all applications can be reconstructed
the specific application scenario of EOS cryptography currency can be explained as:
receiver payment: customers purchase specific procts from the business, and the sales revenue of these procts will be used to pay the business cost, so as to avoid customers paying for the use of blockchain directly, and will not restrict or prevent enterprises from determining the monetization strategy of their procts
authorization capability: if a blockchain is developed by using EOS software system and its token is held by a ticket holder, it may not need to consume all or part of the available bandwidth immediately. Such a holder can choose to give or rent the unused bandwidth to others
separate transaction costs from token value: if the application owner holds a corresponding amount of tokens, the application can continue to run in a fixed state and bandwidth usage. Developers and users are not affected by price fluctuations in the token market, so they are not price dependent
block reward: each time a block is generated, the eos.io system will reward the block generator with a new token. The system may be configured to limit the reward cap for block procers, so that the total annual increase in token supply does not exceed 5%
community welfare applications: users can choose three community welfare applications, also known as smart contracts. These smart contracts will collect tokens based on the proportion of votes each application receives from the token holder. The elected application or smart contract can be replaced by the smart contract of the newly elected application or token holder
What are the technical advantages of EOS
1. EOS creates a developer friendly underlying platform of blockchain, which is similar to the operating system of blockchain. It has powerful performance, can support multiple applications running at the same time, and can support multiple programming languages at the same time. It provides developers with underlying moles to lower the development threshold, just like Microsoft's windows. Do you think Microsoft is worth money
2. EOS solves the problems of delay and data throughput through parallel chain and dpos. EOS can achieve a processing capacity of one million per second. At present, bitcoin has 7 transactions per second, while Ethereum has 30-40 transactions. This super power of EOS can hang bitcoin and Ethereum. For example, the recent cryptokitties | collect and breed digital cats! This is a very popular eth game. Only one game accounts for about 15% of eth's throughput. If there are seven or eight similar games at the same time, ETH will die. It's scary to think about it. Eth, which can't expand bandwidth, will have great challenges in throughput, and EOS can solve the above problems.

5.

EOS is owned by an organization called block.one, but most people contact EOS by Daniel Larimer (BM), a software developer who has been involved in other blockchain projects, including bitshares and steemit, a distributed social network. The CEO is Brendan Blumer, a serial entrepreneur

EOS is considered as Ethereum for large enterprises

EOS public chain allows people to build decentralized applications (dapps) on it and run these applications

according to the developers, the difference between EOS and Ethereum is that EOS solves the performance shortage and availability problems encountered by developers when using Ethereum. There are other small differences that we will discuss below

{rrrrrrr}

extended data:

generation of EOS:

unlike bitcoin, EOS is not obtained by mining. Bitcoin's consensus protocol, known as workload proof, uses a lot of power and can only handle limited transactions

On the contrary, EOS allocated 1 billion EOS tokens in one year's ICO. After that, EOS uses a consensus protocol called certificate of entitlement (dpos) to create the blocks that make up the blockchain

in this system, the community votes for the witness who is responsible for verifying the transaction. If the witness misbehaves, the community members can also vote, and others will take their place

The main features of EOS are as follows:

1. EOS is a bit similar to Microsoft's windows platform. By creating a developer friendly underlying platform of blockchain, it supports multiple applications running at the same time and provides the underlying template for the development of DAPP

EOS solves the problems of delay and data throughput by means of parallel chain and dpos. EOS can process thousands of data per second, while bitcoin has about 7 transactions per second, and Ethereum has 30-40 transactions per second

There is no service charge for EOS, and the general audience is more extensive. The network and computing resources needed to develop DAPP on EOS are allocated according to the proportion of EOS owned by developers

when you have EOS, it is equivalent to having computer resources. With the development of DAPP, you can lease your EOS to others. From this point alone, EOS has a wide range of value. In short, having EOS is equivalent to having a set of rent to collect rent for others, or having a piece of land to rent for others to build a house

8. Five steps to create your own cryptocurrency
when you see how complicated it is to make physical banknotes, it's easy to understand why most people don't try to print new forms of currency every day, but it's also very easy for people with only basic programming level to make new digital currency
programming is not the only step to create a new digital currency. Here are three cryptocurrency manufacturers giving you five steps to follow
1. Using the community to cultivate money
Chris Ellis, an entrepreneur from London and an activist in the feather money community, believes that when you consider making a new digital currency, it's easy to assume that the first step is to start currency programming, which is actually wrong
"the first step is to find a community and build a currency around the community, rather than expecting people to show up after building a currency," Ellis said. "It has to meet the needs of the community and be related to their cultural heritage and background."
Feather coin was created by Peter Bushnell in April 2013. Bushnell resigned as head of it at brechnos college, Oxford, because he wanted to create his own people-centered currency. He made the decision after seeing on bitcoin.org, a well-known cryptocurrency website, that the existing cryptocurrencies (such as bitcoin) lack community participation and inclusiveness
since March last year, Ellis has been actively promoting and teaching people the knowledge of cryptocurrency. Although he had not met Bushnell at that time, he was also aware of the alienation and isolation on the bitcoin forum
"these forums are very technology oriented and are not welcome for newcomers or minorities, and usually smaller teams can better serve these newcomers or minorities," Ellis said“ The forum did not make it easier for people to participate in currency development. A lot of people in these forums come to predict prices rather than actively participate in development. "
Ellis found the cryptocurrency community based on feather coin, and he said that technological development has benefited a lot from the community
"we are a group of feather coin encryption enthusiasts, but some of them may not be so easily integrated into other communities," Ellis said. He said everyone in feather money thought it was important to show that a group of loyal people could build a stable currency. Through cooperation, a dedicated community of encryption enthusiasts can better find and solve vulnerabilities and security threats. For example, the feather coin coding community has successfully resisted 51% of attacks
the establishment of such protective measures and the promotion of currency development can make the currency more legitimate and more easily trusted in the eyes of the public. But if the participants are all passive observers who are only for their own interests, it will be troublesome
2. Programming, for the long-term benefit
surprisingly, every currency developer I talked to said the same thing: "programming cryptocurrency is usually the least time-consuming part of the process. This is because all the cryptocurrencies on the market are based on the open source code of bitcoin or lightcoin provided on GitHub. "
Peter otbach, one of the founders of coino, said: "it doesn't take long to create. It could be only one day, "the company claims to be the fastest cryptocurrency on the market, with a maximum trading time of just 50 seconds“ To start programming, you just need to know C + + to create your own functions in it. "
according to Colin Evans, the developer of quark cryptocurrency, it may take longer than a day“ In terms of programming, the most complex steps may be related to the complexity of the parameters you plan to have in the blockchain, "Evans said“ For example, many currencies just use and the lettercoin code, but quark has a new hash algorithm - that is, it is separate from bitcoin and lettercoin - so if you want to change it, it will be the most difficult one. " In this case, it may take months to program cryptocurrency. However, Evans pointed out that if developers just reuse GitHub's code and change some simple parameters, any competent programmer can do it "in 30 minutes."
but just thinking that anyone with C + + skills can make their own cryptocurrency doesn't mean that one day there will be as many kinds of currencies as IOS applications. "Feather coin is actually a branch of Leyte coin," Ellis said“ It starts with a minimum number of parameter changes, because we think the most important feature of money is viability. "
however, the feather coin team noticed that some of the previous currencies did not last long, because they included a new function, which enables investors to make profits through short-term speculation. However, the team was often unable to manage the project as planned for a long time, resulting in the failure of the project. In other words, those failed currency developers may want to create cryptocurrencies and make profits in the short term, rather than in the long term, which is doomed from the beginning
Ellis said: "you have to be responsible for fixing defects, and you have to make a commitment when you launch the currency, and you have a responsibility to inform people of the risks and protect their property." if you can't, then no one will use your currency all the time
3. Let miners appear on the stage
once you develop currency, you need to spread the information so that people can start to excavate the currency, make people aware of its existence, and hopefully start to get some value in the eyes of miners and users. This is where cryptocurrency manufacturers can't think like programmers, but how humans put trust (and value) in things
Ellis of feather coin explains: "a good start is half done, so it's about building trust, expressing your vision and intentions to miners, who have the hardware they need, and giving them the opportunity to meet future opportunities“ You have to be honest and respect people's expectations and tolerance of risk, which many people value
"overheated money sales can be counterproctive, including new features designed just to try or stand out. Markets can test courage and determination. You need a group of loyal, loyal miners who will deal with the deal even when prices plummet, because they believe in the end result. It depends on good communication and team building
"many cryptocurrencies fail because they underestimate" software ". They think that technology can solve all problems. And then it's not what they think it is. You have to be good at being aware of what needs to be done and be ready to do what others don't want to do. "
4. Know your business
if you've done that. You've conceptualized a good cryptocurrency and brought the right team together to develop and nurture it in your own way. You have spread the news on the cryptocurrency forum, and a large number of miners are actively trying to dig your currency. The next step is to market your currency so that all miners can use it. This is not a small feat. After all, you need to convince indivials and businesses that these currencies created by themselves have value and can be traded like traditional trustworthy currencies
"it's a confidence building process," Ellis said“ It takes good management and time to work out what you really believe and advocate. People will be more willing to buy money based on your motives than your actions, so once you are confident, you have to start discussing your money with friends, businessmen, Internet forums and social media. "
Peter otbach agrees with this view that "to start marketing, you need to find the exact target group," he said, "at first you can start with the cryptocurrency market, because people there know the currency, and you will see their first reaction. It's going to be more difficult after that. You need to convince a lot of people who don't even know what cryptocurrency is, so you have to use money as a payment solution for online stores to attract their attention. "
"I want to add that it's not just about ecating them with facts," Ellis said. "It's about encouraging them to learn and discover their strengths. Money is a classified account. It is a tool that people use to achieve their goals and meet their needs. Knowing this will help you make great progress in marketing. "
Ellis believes that the key to getting merchants to accept money is to understand their different views“ Different stakeholders have the same rules. The difference is that miners are speculative and businessmen are more conservative. " He pointed out that businessmen have three main purposes: to make money, to save money and to raise their awareness“ If we can bring them customers and increase sales while recing the cost of payment, the rest of the job is to persevere and make it as easy as possible for them to start working. "
5. Conclusion
from a professional point of view or a traditional point of view, the last step in the journey of making cryptocurrency is to rule the world with money. But given that no currency has dominated the world for 5000 years, no matter what bitcoin enthusiasts in Silicon Valley say - any cryptocurrency
moreover, cryptocurrency domination "is not necessarily the goal," Ellis said“ Currency can be local. In fact, we think feather currency is a local currency that can serve the global market. "
there may be a real market for emerging cryptocurrencies: local currencies for certain communities, cities, events, venues and people. Build around like-minded consumer groups, so that they can trade quickly and freely, and provide security for the important goods and services in their lives. You don't have to rely on central banks and big markets to tell them that coins and paper money are valuable.
