The age of Ethereum
1. Application of different
digital currency: fast, economic and safe payment and settlement; Bill finance and supply chain finance; The real right of collateral is digitalized
e-money: the seller sends the buyer's payment instructions to the seller's acquiring bank through the payment gateway; The acquiring bank obtains the authorization from the issuing bank through the bank card network, and sends the authorization information back to the seller through the payment gateway; After obtaining the authorization, the Seller shall send the buyer the shopping completion information. If payment acquisition and payment authorization cannot be completed at the same time, the seller should send payment acquisition request to the acquiring bank through the payment gateway, and transfer the transaction funds from the buyer to the seller's account. The final inter-bank settlement is completed by the payment system between banks
2. Different characteristics
digital currency is characterized by low transaction cost, fast transaction speed and high anonymity
e-currency is characterized by anonymity, saving transaction cost, saving transmission cost, small holding risk, flexible and convenient payment, anti-counterfeiting and anti repetition, and non traceability
Digital currency can be divided into three categories: completely closed, unrelated to the real economy and only used in specific virtual communities, such as world of warcraft gold; It can be purchased in real currency but not converted back to real currency, and can be used to purchase virtual goods and services, such as Facebook credit; It can exchange and redeem with real currency according to a certain ratio. It can purchase both virtual goods and services and real goods and services, such as bitcoine-money: e-cash based on the Internet environment and keeping the binary data representing the value of money in the hard disk of the computer terminal; An electronic wallet that keeps the value of money in an IC card and can be circulated out of the bank payment system

Bitcoin is not the only digital currency on the Internet. There are also ripple, stellar, litecoin, Ethereum and other digital currencies. Of course, the most popular is still bitcoin. But many times, some developers, entrepreneurs or enterprises will let us know that we need better digital currency. A programmer named Jed McCaleb, the father of electric donkeys, developed the reborn coin, which should be better than the bitcoin. Later, he launched the star coin, which is better than the reborn coin. What is more gratifying is that he is not fighting alone
now there is a trend that the instry hopes to develop a technology that enables all these online digital currencies to flow to each other, which means that you can transfer money freely in different online digital currency systems in the future. This technology is known as "interleaver protocol (ILP)", initiated by ripote. However, in recent months, that is, after the company released this idea, they also got the support of many famous companies in the instry, including Microsoft and the world wide web. Obviously, Ruibo currency company wants to set the technical standard of digital currency on the Internet. They want to develop a single global network, which can not only unify all digital currencies, but also unify all enterprises and indivials who use these digital currencies
"we want to be on a higher level and extract the differences between various digital currencies," said Stephen Thomas, chief technology officer of ripple. "We are trying to develop a global standard for payment."
with the launch of this agreement, we hope to enable more people to use online digital currency, expand the scope of use of online digital currency, and let us transfer funds more efficiently. This is actually the goal of many existing projects. For example, the original intention of the design of reborn currency and star currency is to allow users to transfer money to these two digital currency accounts in any currency, and to enable these two digital currencies to be converted into other currencies correspondingly. You can send bitcoin, and then the other party gets it. You can also send us dollars, and the other party will get dogecoin. However, for businesses and the developer community, there are restrictions on their use of these ledgers, so there are some problems because you can't transfer money from one payment network to another. Now, however, the interleaver agreement hopes to change that
to some extent, after ten years of efforts, they hope to develop a new network protocol, which is commonly known as "money Internet". If we go back to the early 1990s, we know that the famous Marc Andreessen founded the Netscape web browser. Now, the project hopes to play a similar role. They want to establish a standard way to send funds on the Internet. In fact, the original Hypertext Transfer Protocol (HTTP, which defined the basic standard of the network) contained code for payment. But this code has never been used. In recent years, many companies (such as coinbase, a bitcoin exchange, and stripe, a company that helps enterprises accept various online digital currencies) are at least trying to create a conventional standard for online digital currencies. In the future, we hope to be able to send and receive money online, just like sending short messages or e-mails. However, we still have a long way to go to this paradise, but at least now we are in the right direction
network virtual currency can be roughly divided into
the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third kind of virtual currency on the Internet, such as bitcoin (BTC), Fuyuan coin (FTC), Wright currency (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency.
money circle, one day, ten years on earth
the high housing prices destroyed the post-80s and post-90s
and then the world came back. Today's virtual currency
the post-80s also pulled back a round. Whether it is worth buying is not to see whether its current price is high or low
but to see whether it has value in the future and whether it will be useful for everyone's life There must be only a few bitcoins in total.
bitcoin has become a kind of value preservation proct corresponding to gold
decentralized anonymity advantage
bitcoin comparable to gold
moreover, more and more businesses have accepted bitcoin transactions
some institutions have also accepted bitcoin donations, and bitcoin ATM has become a hot topic Put into use
the second is
Ethereum (ETH)
it can be said that it is an evolutionary version of bitcoin
bitcoin is gold, Ethereum is silver
Ethereum's technology can be applied to real world applications
JPMorgan Chase, Microsoft, etc. are all optimistic about Ethereum technology
In my opinion, the most stable return is the twoand the other multifarious currencies have gone up and down sharply. Ordinary people's hearts can't stand
at present, domestic users can buy through this website
transactions
it's not the price rise of the currency but the price rise of the currency through the bar The number of coins is rising
1、 General situation of mineral resources (1) discovered minerals and ore procing areas by the end of 2005, 138 kinds of minerals have been discovered in the whole region, accounting for 80.7% of 171 kinds of minerals in China. There are 81 mineral resources (102 subspecies) with proven reserves. There are 87 oil and gas fields with proven resource reserves, including 10 large, 43 medium and 34 small ones. There are 993 proven non oil and gas procing areas, including 137 large, 210 medium and 646 small ones
During the Tenth Five Year Plan period, there was no change in newly discovered minerals compared with the end of the Ninth Five Year Plan period. There were 7 more minerals (natural asphalt, antimony, strontium, andalusite, pyrophyllite, basalt, perlite) with proven resource reserves, 13 more oil and gas fields with proven resource reserves, and 127 more non oil and gas procing areas with proven resource reserves. See table 3-1
Table 3-1 ring the Tenth Five Year Plan period, the situation of discovered minerals and proved ore procing areas in the autonomous region is as follows: (2) general situation of retained resources and reserves. Among them, natural gas, iron ore, gold mine, silver mine, cesium mine, andalusite mine, Glauber's salt mine, sylvite mine, asbestos mine, limestone mine for cement, bentonite mine, granite mine for decoration and marble mine for decoration increased by more than 19% (see attached table 10). See table 3-2 for the increase and decrease of main mineral reserves in 2005 compared with that in 2000
Table 3-2 increase and decrease of main mineral reserves in 2005 compared with that in 2000. See table 3-3
During the Tenth Five Year Plan period, 3652 new non oil and gas mineral exploration licenses were approved in accordance with the law. Among them, there are 239 energy minerals (223 coal mines), 528 ferrous metal minerals, 1322 non-ferrous metal minerals, 892 precious metal minerals, 62 rare, rare earth and scattered minerals, 571 non-metallic minerals and 38 water vapor minerals. It is one of the top three provinces (regions) that issue the most exploration licenses in China (Inner Mongolia, Shandong and Xinjiang in turn). See table 3-4 and Figure 3-1
Table 3-3 by the end of 2005, the reserve of main mineral resources in the autonomous region ranked among the top 10 minerals in China
there were 8 Sino foreign joint ventures and wholly foreign-owned mineral exploration enterprises registered in the autonomous region, with a total approved exploration license area of 1300 square kilometers
During the Tenth Five Year Plan period, 13300 mining licenses for non oil and gas minerals were approved in accordance with the law in the whole region (the licenses issued by land and resources management departments at prefectural and municipal levels are mainly small construction placer and clay minerals), of which 2224 were newly issued
Table 3-4 new license issuing situation of exploration license in the autonomous region ring the 10th Five Year Plan Period, 821 changes were handled and 1040 mining areas were demarcated. See table 3-5 and figure 3-2
Table 3-5 list of new mining licenses issued by the Department of land and resources ring the Tenth Five Year Plan period unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: unit: Unit, Collective enterprises decreased by 31.7 percentage points, limited liability companies increased by 15.4%, and private enterprises increased by 14.7%. The data show that the pattern of investment in mineral resources development has changed greatly
there are 19 Hong Kong and Macao businessmen and foreign-invested enterprises developing mineral resources in our region, accounting for 10.2% of the 187 Hong Kong and Macao businessmen and foreign-invested enterprises that have obtained mining licenses
The construction of mining right market is a new task, and there is no ready-made experience to follow. At the same time, it is an important task for geological and mineral administration. In order to establish a standardized, orderly, unified, open and reasonably competitive mining rights market, first of all, Hami, Altay and Tacheng regions, which are rich in mineral resources, high mining output value and well managed, are selected to carry out the pilot work of mining rights transfer(1) Altay is rich in metal and rare metal mineral resources, but the degree of geological work is low, the level of mineral resources reserves is not high, and there are many scattered small mines. Altay Bureau of land and resources tried to transfer the mining rights of scattered small mines by agreement, and achieved good results
(2) Tuoli County in Tacheng area is rich in granite resources, among which the variety of "tuolihong" granite is popular in the market. Because there are many mining sites, the quality and price fluctuate greatly, which affects the orderly development of mining economy in the county. Through the rectification, the mine that issued the license beyond its authority was closed down, the mining area was re planned, four mining rights were set up, and the price of 1.1 million yuan was used for bidding, which achieved good results
(4) the natural environment of Hami region is relatively good and the resources are rich. In August 2002, through investigation, Hami Municipal Bureau of land and resources selected the "Tianshan Baima" facing granite varieties with good market prospect and low transportation cost adjacent to the national highway, i.e. No. 1 and No. 2 orebodies of Liugou granite in Hami City for auction, and successfully determined the first hammer for the whole district to sell mining rights by auctionon the basis of the working experience of mining right agreement transfer and auction in pilot units, the Interim Provisions on the administration of mining right bidding, auction and listing transfer (new land and resources development [2002] No. 134) was formulated and issued to guide and standardize the paid transfer of mining right in the whole region
In order to cultivate and standardize the mining right market of the whole region and speed up the construction of the mining right market, according to the mineral resources law, supporting laws and regulations and the relevant requirements of the Ministry of land and resources, In 2001, the implementation plan for further rectifying the mining economic order and standardizing the mining right market in the autonomous region (new land and Resources Office [2001] No. 175) and the notice on strengthening the management of mining right transfer and cultivating and standardizing the mining right market (new land and Resources Office [2001] No. 244) were formulated, Land and resources departments at all levels are required to conct in-depth investigation and investigate illegal transfer of mining rights in accordance with the law, and promote market-oriented management of mining rights. In order to standardize the bidding, auction and listing of mining rights, increase the market allocation of mineral resources, and rece the transfer of mining rights by administrative examination and approval, the notice on stopping the transfer of mining rights of building materials minerals by administrative examination and approval (new land and Resources Office [2002] No. 459) was formulated on the basis of summarizing the pilot work of the transfer of mining rights, The establishment of the above documents and systems has played a positive role in the construction and standardized development of the mining rights market in the whole region Since the implementation of the administrative measures for bidding, auction and listing of exploration rights and mining rights on August 1, 2003, the whole region has actively studied and formulated the paid use system of mineral resources in line with the local reality, and further cultivated and standardized a unified, open, competitive, orderly and dynamic mining rights market system, "Two rights" bidding, auction, hanging "transfer has increased significantly, the degree of marketization of mining rights has graally improved, and breakthrough progress has been made in the construction of two rights market(1) listing transfer of mining rights of construction placer and clay ore. After the mining right market of the whole region started, the paid transfer of construction placer and clay mining right was first included in the agenda of mining right market construction. Taking advantage of the opportunity of mining order rectification and mining management in scenic spots, we first carried out the paid transfer of mining rights of sand and clay mines in Turpan. The non coal mines in Shanshan county were re planned, and only 6 sand and stone mines were set up in the county. Shanshan County Bureau of land and resources openly sold two sand and gravel mining rights in Sanchakou of the county town to the public by way of listing. The initial price of listing was 200000 yuan. After 15 and 29 rounds of listing bidding, the two mines sold for 2.44 million yuan, becoming the first sand and gravel mining right sold by way of listing in Xinjiang
(2) coal mining right auction. In order to further promote the construction of mining right market, according to the development planning of mineral resources and market demand, the mining right of Heishan coal mine in tuokesun County, with proved reserves of 25.66 million tons, thick coal seam and good mining conditions, was selected for auction. On November 18, 2002, the mining right of the mine was sold at 9 million yuan. After 33 rounds of bidding, it was sold by Xinjiang Guanghui granite mine development Co., Ltd. at a price of 49 million yuan, becoming the first coal mining right sold by auction in China (3) the important mineral exploration rights and mining rights are transferred to the public. In March 2004, according to the requirement of "emancipating the mind and achieving breakthroughs in the development of mineral resources in Xinjiang" put forward at the sixth (enlarged) meeting of the sixth session of the Sixth Party committee of the autonomous region, 13 exploration rights and mining rights of coal mine, gold mine, copper mine, iron ore, magnesite, potash and other important minerals were transferred to the public, of which 7 exploration rights and mining rights had a total starting price of 38.6 million yuan, The auction price was 183 million yuan. In particular, the meisbulake coalfield in Baicheng county (a total of three minefields) has a total starting price of 29 million yuan and an auction transaction price of 172 million yuan, which has strong repercussions in the society. At the same time, the people's Government of the autonomous region attaches great importance to the exploration right and mining right(4) the mining right evaluation unit is determined by "shaking beads". In 2005, in order to reflect the principle of fairness and justice and improve the transparency of mining right examination and approval, our district took the lead in determining the mining right evaluation unit by "shaking beads" in China
During the Tenth Five Year Plan period, we actively explored the transformation of the management mode of mining rights, made efforts to settle the unemployed workers and social stability, and promoted the economic development of the autonomous region. For example, a state-owned ceramic factory in Urumqi, with two small coal mines and one clay mine for ceramic making, was on the verge of bankruptcy in 2001 e to poor management. The staff and workers of the enterprise are living in distress and petitioning constantly, which has affected the local social stability. In accordance with the instructions of the leaders of the autonomous region, our department has invested 3.6 million yuan of the mining rights originally obtained free of charge by the enterprise as a share of the resettlement expenses of the enterprise's employees, introced new capital technology and new management methods, revitalized the assets, and revitalized the old enterprises. Another example is an old state-owned gold mine in Hami. Due to the chaotic operation and the depletion of proven resources, the enterprise went bankrupt, and the placement of workers became a major difficulty. After negotiation with the Department, Hami District auctioned the four mining rights obtained free of charge by the original enterprise and the fixed assets of the bankrupt enterprise, and finally concluded the transaction with 11.08 million yuan, which effectively protected and utilized the original mine resources, guaranteed the life of the enterprise staff, and accumulated experience for the disposal of the mining rights of the bankrupt enterprise (3) explorationit is also closely related to Internet technology and has the attributes of payment and circulation. The central bank's "digital currency" is closely related to bitcoin. But bitcoin is a kind of digital currency, but digital currency is not just a form of bitcoin. Although the central bank's "digital currency" veil has not yet been lifted, there must be many differences with bitcoin
first of all, the issuers are different
most currencies have an issuer. For example, RMB is printed and issued by the central bank. But bitcoin does not have a centralized issuer. It is generated randomly based on an algorithm. Anyone can mine, buy, sell or receive bitcoin
secondly, the acquisition methods are different
bitcoin is the result of unremitting "mining" by some people who master the algorithm. These real it experts need to search for 64 bit numbers by computer, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network and obtain the corresponding bitcoin
but the digital currency issued by the state is bound to face the people of the whole country, rather than some network experts. When the country strives to achieve the goal of Inclusive Finance, how can it only tailor a currency for Internet experts? The national version of "digital currency" is bound to help the realization of Inclusive Finance, facing the most extensive groups.
