Ethereum replacement
Digital money is legal
digital currency itself is legal in China. Digital currency is defined as Internet goods in China, but the relevant supervision is still blank, and digital currency is still in the gray area in China. Well known digital currencies include bitcoin, Leyte coin, Ruitai coin, thousand gold card, dog coin, etc
however, there are also some non developers who use the cover of digital currency to carry out pyramid schemes, such as the Vicat scheme, treasure scheme, Porter scheme and so on
development materials:
digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency
the number of atoms in the universe is between the 78th power of 10 and the 82nd power of 10. That is to say, 24 words are randomly selected from 2048 words in bip39 thesaurus for permutation and combination, and the magnitude of the answer is similar to the number of atoms in the universe
if we want to get a mnemonic word of bitcoin wallet from these 2048 words, the probability is about 677 billion divided by 1 * 10 to the 78th power, and the result is 6.77e to the - 70th power. This is a very small number. Therefore, the probability of getting a bitcoin wallet from 2048 words is very, very low, let alone from Nakamoto's wallet
of course, we don't rule out the element of luck, in case you hit the mnemonic word of Nakamoto's wallet. Then you can really get instant wealth and freedom, and more importantly, you can cheat people that you are Nakamoto. So, as long as you have perseverance and courage, you can have a try. After all, there is a very good saying: there should be dreams, in case of hell.
1. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
2. Unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation
3. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
don't be cheated any more. The air bitcoin club is a pyramid scheme
however, it will be difficult today in 2018. For a while, "bitcoin" and "lightbank", for a while, dogcoin culture, for a while, reborn has deeply cooperated with many banks around the world, for a while, dark coin can be anonymous to the end, and for a while, Ethereum has successfully crowdfunding
however, more often than not, you will encounter serious bitcoin loyalists, who would like to remind you that only bitcoin will be favored by Wall Street, investment banks, venture funds, big companies and multinational governments, and will be invested with real money and silver. Other currencies are cat and have no future. They should be returned to zero, so be careful
however, I often see Jiang En of China Dog Coin Association and his gang of dog fans. They are always amazed at an activity, blinding the eyes of the coin fans once. In 2015, they solemnly held a "China's first digital currency application creative competition"
let's get down to business. Whether you are anxious or confused, you should not forget that you are an investor today and put money in for profit. So, should we hang on a big tree of bitcoin What if it doesn't catch up with the stock Or actively participate in some reliable competition What if it's not recognized and returned to zero It's so hard. Who knows the pain of our digital currency
at the level of investment and speculation, the evil of monopoly is that when it has sole or totalitarian power, it will make the world unstable by unscrupulously manipulating resources, making rules, restricting competition, gaining price hegemony and squeezing higher profits. For the cryptocurrency of blockchain distributed record, which challenges human's extreme thinking, we can't find the evidence of monopoly in reality, but we will certainly associate with the dark manipulation of the United States on quasi currency and bulk energy commodities such as gold and oil
gold rose from US $300 in 2002 to US $1922 in 2011, a 6-fold increase in 10 years, and then fell to RMB 1200 at the peak of the bull market. This precious metal, which once served as a currency, has become a tool for Wall Street investment banks to cut off global investors by derivative leverage trading
the same goes for oil, which rose from US $10 a barrel in 1998 to US $147 in 2008, and then dropped to US $33 in 2009 in the next few months. This largest energy commodity with fixed reserves and stable proction costs has become a meat sauce on the speculative capital chopping board. Everything is caused by monopoly or uniqueness. In this price war planned by hegemonic countries and chaebols, the wealth of the world keeps flowing into wall street
assuming that humans eventually accept only bitcoin as a digital currency, the US government, which has lost its US dollar monopoly, will not agree to it. It will certainly pursue monopoly at all technical levels, such as bitcoin protocol improvement, software upgrade and maintenance, wallet update management, and transaction rule making. As long as other countries refuse to accept, it can use all political and monetary resources Armed by military forces, hackers and inced by public opinion, bitcoin has been forced to obey all over the world and eventually turned into a financial power tool for Americans
Wall Street will not stop. With the connivance of the U.S. government and the Federal Reserve and the support of foreign creditors' trust in the U.S. dollar, Wall Street will print U.S. dollars, buy and hoard bitcoin in large quantities, turn bitcoin into a tool of speculative manipulation like gold and oil again, and let Americans continue to cut off the leeks of people all over the world, People's pursuit of decentralization will come to nothing
only when the issue of digital currency is not unique, unlimited and exclusive, will people calmly abandon one or several currencies in case of monopoly and manipulation, and choose another new currency with more fairness and credibility to replace it, so as to eliminate manipulation, hegemony and monopoly that may exist in one or several fixed currencies Privilege, centralization, exploitation and corruption
therefore, in order to ensure the steady development of digital currency, it is necessary to set up a mechanism not to be destroyed by centralization and monopoly. Then, it is the general trend that bitcoin will survive and die together with other competitors. The idea that bitcoin will be the king for a long time because of its preconceptions and despise all competitors is narrow-minded. As an ordinary investor, under the background of paying attention to the long-term stable and slow upward trend of bitcoin price, we should pay proper attention to competitive currencies with pure agreement, global recognition and small market value, such as integrity currency CXC, which may really have the opportunity to enjoy short-term windfall profits.
According to the news on the morning of December 22, according to the latest tax reform plan of the Republican Party of the United States, investors in bitcoin and other virtual currencies will lose an attractive tax preference
under the current tax law of the United States, such transactions are protected by a clause that allows investors to postpone the payment of capital income tax in so-called "similar transactions"“ "Similar transactions" traditionally refer to real estate, art, horse racing and aircraft transactions. If the asset owner replaces his assets with other assets of the same type, tax payment can be postponed, usually for 180 days
with Ethereum officially confirming erc-721 as one of the new token standards, many people are asking what erc-721 is recently. There are many technical posts on the Internet to analyze the code differences between erc-721 and erc-20. They are very unfriendly to Xiao and leek. With the attitude of sharing knowledge, I will try to explain the most significant differences between erc-721 and erc-20 with intuitive words
erc-20 standard token:
1
2. It can be subdivided into N parts (n = 10 ^ 18)
conclusion: similar to the currency in real life, it can perform all monetary functions. The application cases are similar to legal currency and virtual currency
erc-721 standard token:
1
2. The minimum unit is 1 and cannot be subdivided
summary: non homogeneity exists widely in life, such as art, pets, handicrafts, custom-made items, etc., and can even be used to mark students in schools, doctors and patients in hospitals, etc. The application scenarios are very wide
the above description is relatively concise. Taking a look at specific projects can help you better understand erc-721 standard. At present, the popular projects using erc-721 standard can take a look at
- cryptokitties (cryptokitties | collect and breed digital cats!)
this is the "ethereal cat" mentioned before. It's very basic and interesting. Each cat is a token with unique attributes. The more unique the attributes, the higher the value of the cat. It's very popular, but its development potential is limited
- 0xcert (0xcert - supporting uniformity.)
this project is a recent project of personal interest, which is close to life and easy to implement. Erc-721 token is used to mark real-life artwork or a unique item, and record the basic attributes, characteristics, value, previous owners, etc. It is very helpful in combating counterfeits and piracy. It may also be used in the second-hand market, exchange of valuables and other scenarios in the future
personally, I am very optimistic about erc-721 standard. After the whole blockchain instry calms down from the carnival, the implementation of the project has become the first consideration for developers, and erc-721 is very suitable for connecting the blockchain with the real world.
I don't think bitcoin will collapse
I started to contact bitcoin in 14 years. At the beginning, I just wanted to find a part-time job. I heard that mining can make money, so I started to contact bitcoin from mining
at that time, when I bought an ant miner, the seller registered a bitcoin account for me and debugged the machine. When I got home, I just needed to connect the Internet cable and power supply to start making money. At that time, the profit of a machine was about 40 yuan a day, and it cost more than 20000 yuan to buy that machine
at that time, I didn't know much about blockchain and virtual currency, and the information available on the Internet was not comprehensive enough. At that time, I thought it was similar to the running score of the game
later, the mining became popular, and the graphics card became a hot proct. My miner sold again for 30000. At that time, I didn't buy and sell graphics cards and made a small profit. But they didn't realize the value of bitcoin
