Research and development of decentralized system
mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary.
however, bitcoin is still the most popular decentralized virtual currency so far, but no one can guarantee that it will always be in this position. Now there are some alternative currencies inspired by bitcoin. However, a more reasonable assumption is that the new currency needs significant improvements to replace bitcoin in the established market. Of course, these are still unpredictable. Without changing the basic composition of the protocol, bitcoin may also adopt some measures to improve the competitive currency
I feel that Shanzhai currency can only occupy some bitcoin markets, but it can not replace bitcoin. For example, dog money has seized the charity and small reward market; Fuyuan currency seized the market of commercial integral system; Diablo has taken over the geek market (better sex) and so on.
1. Cultural and entertainment chain: the cultural and entertainment chain takes advantage of the characteristics of blockchain, such as decentralization, openness, information tampering, and so on. It claims to build an "IP asset exchange", issue its own token for a high-quality IP, solve the problems of realization, protection, and management of the cultural and creative IP instry, and build a weakly centralized, traceable, digital, and capitalized cultural and creative instry ecosystem. But in fact, when they enter their community, the nature of the swindler will be exposed. They promise to go to the major exchanges such as Shanghuo coin, promise that the opening price will not be less than 2 times of earnings, promise that they will only go up but not go down, promise that they will not break, promise that they will not attract funds, promise to carry out pull propaganda, and hope to raise the vigilance
2. Ant chain (antc): ant chain is antc. It claims to be the token of decentralized digital asset trading system, and publicizes a of antc white paper in various wechat and QQ groups. Many people mistakenly believe that antc is raising money for fraud, There is no investment value at all
the "genuine" ant chain, which has been replaced by an impostor, is a company committed to building an intelligent transportation network through digital assets and blockchain ecosystem. It is located in Boston, USA. however, the company has only launched the ant bike
3. Sharing chain Mall: sharing chain is known as an intelligent, credible, open and decentralized credit data value platform based on sharing economy. It is the underlying structure based on sharing economy built by blockchain technology. As long as consumers shop in the mall, they can get the special benefits of the mall
4. Posevo (POF): posevo environmental protection token, which has been publicized since January 2018, is called POF for short. It has issued 700 million pieces in constant volume and will never be added. The issuing period is 4 years. The development source code is ethereum erc-20, and the original issuing unit price is 1 RMB / piece. Take static income as an example: angel investment of 1000-20000 yuan. Return 3% of the investment amount every day, ending with a total of 3 times of the investment amount. For example, if the investment is 1000 yuan, return 3% of the investment amount every day = 30 yuan, return 100 days in total, and return 3000 yuan to the investor. It is the pyramid selling mode. After investigation, mesworth token did not use any blockchain technology, nor did it log on to any exchange as mentioned in the publicity
the latest technology application of blockchain: born out of bitcoin technology in 2008, it provides a decentralized credit establishment paradigm without trust accumulation. The essence of blockchain technology is a decentralized and distributed data storage, transmission and proof method. It replaces the dependence of the Internet on the central server with data block, so that all data changes or transactions are recorded on a cloud system. In theory, it realizes the self proof of data in data transmission, This kind of point-to-point verification will proce a "basic protocol", which is a new form of distributed artificial intelligence. It will establish a new interface and sharing interface between human brain intelligence and machine intelligence
at present, almost all decentralized virtual currencies will use blockchain technology, such as bitcoin, Fuyuan, Laite, doggy and so on.
first, dog money Innovation:
by introcing the essence of consensus in global dog culture, we are determined to become a digital currency for building interesting and friendly community relations<
application scenarios of dog coin:
charity refers to charity in Europe and America. Its concept is larger than that in China. In addition to helping the weak and the poor, any act of love and sharing from the heart is charity. For example, it is charity to subsidize a teenager to participate in the e-sports competition
reward - starting from rewarding editors or those who share excellent content and software works, dog coin will bring positive and far-reaching influence to the world by expressing gratitude, appreciation, friendliness and encouragement
characteristics of dog coin:
dog coin is a rare currency that has not experienced speculation, but its popularity has been good
in order to develop dog coin, we should promote it from "traditional means" to a large extent, such as cooperation with pet businesses<
Second, the application innovation of Dash:
anonymity - the anonymous sending of dash is completely untrusted, because no one can control the whole system, but the probability of problems is very low
by the way, many people think that digital currencies have anonymity, but the reality is just the opposite: most digital currencies do not have anonymity
bitcoin is a typical example of non anonymity. In the past seven years, all kinds of news reports have been misinformed, resulting in many people still think that bitcoin can be anonymous and even become the best tool for money laundering
invest in bitcoin. Unless hackers close their eyes, your wealth will be under their eyes
instant - dascoin has a lightning trading mode, called instantx, which can complete the transaction in a few seconds (usually only one second)
compared with bitcoin's 1-hour transaction completion time, dascoin's arrival speed is very fast
Security: it's natural to be anonymous. Its advanced encryption and two-layer network mode will bring strong security
decision making engine: dascoin's decentralized blockchain management system allows anyone to propose changes or upgrades to dascoin
whether it's legal, marketing or other suggestions, they can be directly submitted to the network through the blockchain. The selected proposal will pay 10% to the new block
the community votes on the proposal every month (only the node holder has the right to vote)
at least 10% more affirmative votes than negative votes are eligible, and there is competition between proposals. The monthly bonus is about 8000 dashes<
self sufficient budget system - budget system or self financing of dascoin allows anyone to provide their own budget and initiate a proposal on the development and publicity of dascoin
the budget system and decision engine make dascoin an independent, decentralized and autonomous currency
Yes, dash itself is probably the first decentralized autonomous organization (DAO) in the blockchain instry<
application scenario:
hope to make achievements in the field of anonymous investment, and strive to build a decentralized and sustainable anonymous financing mode
instant payment under certain demands, such as dascoin, has caught up with bitcoin and entered the ATM market through bitcoin
strictly speaking, bitcoin can't do zero confirmation transaction. It usually takes 3-6 confirmations for bitcoin to confirm a transaction once every 10 minutes before businesses can recognize the success of the transaction. (another factor is the limited capacity of bitcoin blockchain. When the transaction volume breaks out, many people will increase the handling charge, and miners will give priority to the transaction with high handling charge, And may cause your transfer to be delayed)
dascoin is not. Its instantx function can solve the problem of zero transaction trust, and the speed of reaching agreement in dascoin's master node network is amazing, which usually takes only one second
finally, bitcoin wallets are generally confirmed six times, and users will not be allowed to use the new money until one hour after it arrives, which is obviously not concive to the emergency needs of small transactions
therefore, for ATM services that need instant deposit and withdrawal, by eliminating business risks and greatly speeding up the speed of account arrival, dascoin has the upper hand<
other features:
anonymous sending uses the addresses in the very large address pool inside the wallet to confuse frequently
when anonymization is carried out, a large number of transactions will be generated in the background, which means that wallet files need to be backed up frequently
in order to ensure security, it is necessary to back up a new wallet file after each anonymous confusion
do not run wallet programs in different places at the same time. If you do this, you will have automatic anonymous synchronization, and the problem of "double flowers" will occur
dash, formerly known as darkcoin, was used by pyramid schemes because of its anonymity
the most serious case is "Liu Xiong's pyramid scheme with black money". In August 2014, the MLM organization hired a lot of staff to make the official website of "dark money", create a false online trading platform and start the operation of the website
in order to support the false "dark money" investment, the core figure of the MLM organization set up Dakang Intelligent Technology Co., Ltd. in Hong Kong, China
based on this, we take people to the headquarters of the company for investigation and study (every afternoon, consultants will give lectures to teach the concepts of "virtual currency", "dark currency" and other concepts, as well as marketing skills)
in just 8 months, 3 members of the Chinese mainland have developed more than 3 members (counting by accumulating accounts), and nearly 1 billion 500 million yuan has been accumulated. Although the fake "dark money" website established by this pyramid selling organization has nothing to do with the real "dark money", it only uses the reputation and value of "dark money" to make a lot of publicity, so as to achieve the purpose of confusing the public
however, there are still many people who do not know the real situation, and even suspect that the black money is involved in it. As a result, the dark coin had to be completely changed. English name, Chinese name, currency symbol, logo and official website domain name were all replaced
however, because the trial time of the case is very long, the case is still hot in the news after the replacement. Some people who don't know why changed the name of "Liu Xiong's pyramid selling case of dark coins" to "Liu Xiong's pyramid selling case of Dashi coins", which still cast a shadow on Dashi coins
this story tells us that the complexity of digital currency technology makes it impossible for the public to digest in a short time, so the confusion, confusion and danger in the early stage are inevitable
in addition, the number, activity and longevity of MLM organizations in China in recent years, as well as the amazing amount of money collected from MLM cases, not only remind people to be cautious in screening, but also illustrate the poor domestic environment and low efficiency of law enforcement
dascoin is the first of many competing currencies and the only cryptocurrency that has entered the bitcoin ATM market when I write here - that is, dascoin can be extracted from bitcoin ATMs
economist Ashe Whitner (currently working for europacific capital, a global network of more than 600 corporate governance expert groups, tax lawyers, trust advisers and portfolio managers to manage all B2B referral partners) made special mention of arriving at the world currency in an interview and said that in his opinion, Dascoin is a more perfect and flexible management system than bitcoin and most other cryptocurrencies
Ashe Whitner once met with the creator of dascoin, Evan Duffield. Through contact, he thought that Evan Duffield had a great plan here<
Third, integrity currency
Innovation: by introcing the essence of consensus in the credit reference culture, we can protect the credit rights and interests from infringement of digital currency
application scenario: credit investigation - credit transaction, digital assets generated by honest transaction
reward every person who cherishes credit through one visit, bringing positive and far-reaching influence to the world
features: honest currency is a currency that has not been hyped, but its popularity has always been good
to a large extent, it can be developed because under the condition of asymmetric information, everyone needs to open accounts to make information and data symmetrical, and more importantly, it needs regional centralization to ensure the capital security of each transaction
in order to eliminate the credit problem under the condition of information asymmetry.
