1. Will El Salvador become the preferred residence for crypto entrepreneurs?

The President of El Salvador, Bugle, announced on June 6 that El Salvador is expected to become the world’s first After making Bitcoin a legal tender, El Salvador once again mentioned four major benefits for cryptocurrency entrepreneurs on Twitter.

AFP news on June 6 pointed out that at the 2021 Bitcoin Conference in Miami, Florida, USA, Nayid
Bukele said, "Next week I will let Bitcoin The bill for the currency to become legal tender is submitted to Congress." This move will make the country the first country in the world to officially accept cryptocurrency as legal tender, and will also "allow thousands of people outside the legal economy to be included in the financial system." . He pointed out that "70% of the population in El Salvador has no bank accounts and works in the informal economy" and this bill aims to create job opportunities. The El Salvador government has not yet provided details of the bill, which will need to be approved by Congress dominated by Bugle's allies.

Already last year, as the pandemic hit the tourism industry hard, the village of El Zonte in El Salvador embraced Bitcoin-powered alternatives to traditional financial solutions. An anonymous donor "allocated a multi-year, six-figure donation to ElZonte." Participants can currently use Bitcoin and the Lightning Network to purchase goods and even pay utility bills, and promising students can also receive Bitcoin funding. As early as March last year, the popularity of Bitcoin was also showing in El Salvador. In March, GoogleTrends data showed that the top five countries in the world for the search popularity of the word "Bitcoin" were: Nigeria, El Salvador, Ghana, Austria, and Germany.

Bitcoin has been around since
2009
and has gradually appreciated in value over the years under the radar of most people. However, in just two years, the world has witnessed the rapid rise and subsequent price correction of Bitcoin and hundreds of other cryptocurrencies, altcoins, and tokens. As cryptocurrency bubbles come and go, the debate continues over whether the cryptocurrency and blockchain story is a success or a failure, at least for now. There has also emerged a class of crypto high net worth individuals, many of whom are young, globally mobile and eager to consolidate and enjoy their newfound wealth. El Salvador has clearly become one of the most advantageous places to accept new things, and its subsequent development is worth looking forward to.

Compared with traditional communication technology, the characteristics and advantages of quantum communication technology are reflected in its higher timeliness, stronger anti-interference, better confidentiality, and required Low signal-to-noise ratio, etc.

In terms of policy, our country has introduced a number of policies to promote the development of quantum communications. The "14th Five-Year Plan" that will be implemented in 2021 proposes to increase the entire society's R&D investment by more than 7% per year on average, and to expand quantum communication. technology, along with artificial intelligence and semiconductors, are listed as key R&D targets.

In terms of technology, China has more than 3,000 quantum communication patents, leading the United States. As the country gradually improves the top-level design in the field of quantum technology and strengthens technical support, my country is expected to become the main promoter of global quantum information technology research and application.

Quantum communication has obvious advantages over traditional communication

Compared with traditional communication technology, the characteristics and advantages of quantum communication technology are reflected in its high timeliness and strong anti-interference It has good confidentiality, low signal-to-noise ratio, etc. The delay of quantum communication lines is almost zero, the information transmission speed is fast, and the process is obstacle-free; the information transmission in quantum communication has nothing to do with the communication medium between the communication parties, is not affected by the space environment, and has perfect anti-interference performance;

Since quantum cannot be cloned, it becomes the basis of quantum keys. Quantum cryptography is highly secure and generally cannot be deciphered. Compared with traditional communication methods, quantum communication technology obtains the information required for reliable communication under the same conditions. The noise ratio is 30-40dB lower.

4. Shell Currency: The most successful ancient blockchain economic experiment

This account is a news & NetEase account ""Everyone has his own attitude" signed account. The concept of contemporary blockchain has been around for just over 10 years. Years ago, there were cases of similar attempts in the long past. What’s more, this type of mechanism has been closely related to the monetary economy from the beginning. You may think that shells are primitive and outdated, but their history as currency has been prevalent in many areas. 19th century. Even today when Internet mobile payments are popular, some countries still use it as a recognized legal tender. 1 The original distributed accounting shell is the earliest known currency. The history of shells as currency has been blurred and cannot be tested. But before human society entered metal coins, shells were already everywhere in various groups on the five continents. In an era when intercontinental movement was not convenient, shells had such a powerful payment influence, which shows that they had great value in the hearts of primitive humans. and a sense of presence. Since early humans did not have transportation technologies such as wheels and horses, boating became the best choice for movement and transportation. In addition, rivers, lakes and seas are rich in aquatic products, which can easily attract a large number of people to come for fishing. Among them, shellfish And because there is little ability to escape, it is easier to become a readily available food to satisfy hunger. Correspondingly, early works of art using shells as raw materials also became popular. Most of the initial necklaces, bracelets, earrings or pendants used shells as raw materials, and gradually It has exchange value. The economic development of the Neolithic Age gave rise to the demand for trading media. As the number of human communities increased, the development of early agriculture and animal husbandry produced a large amount of surplus products. Therefore, exchange behavior in different regions began appeared. However, most agricultural and animal husbandry output has only a short shelf life, and it is inconvenient for exchangers to carry large quantities, forcing humans to seek a relatively stable and abundant trading medium. Shells that already have a stable output will follow the trend and become became the first currency in human history. Beyond many people’s inherent understanding, shell currency has evolved fromIt has the characteristics of distributed accounting from the beginning. Although many people will make a comparison with today's national currencies, Shell Exchange actually does not have a clear concept of centralization. Every coastal or riverside tribe can go to the waterside to "dig" and then process it into a relatively neat form. The only industry standard is that the medium needs to be shellfish shells, not the remains of other organisms. Even though Some residents of the American interior came up with a whim and created similar forms of snail shell coins, but they could not continue to go beyond this category. Looking for shells by the river is a primitive "mining". As for the very important specific value, it is completely unknown. It depends on the negotiation results between the two parties. In other words, not only the purchasing power of shells will fluctuate with the amount of materials, but the price itself also has many variables in the circulation process. A resident living in the inland may buy shells out of speculation. After obtaining a large amount of shells, they soon found that their prices dropped due to various force majeure factors. This is mainly because shells, as currency, lack the reserve system necessary for modern financial products. The production of shellfish species may completely decline due to natural factors. Suddenly high and sometimes low. People can't come up with reliable products with stable value as an endorsement of their own Shell coins. Therefore, Shell is a typical barbaric growth stage and has many similarities with the early blockchains of later generations. Shell The value of currency fluctuates very sharply 2 Facing the challenge of precious metals Early Minoan copper coins in Crete Once human society entered the Bronze Age, the limitations of shell currency were exposed. The birth of bulk commodity trading made merchants and managers even more People were intolerant of shells without endorsements. As a result, the first precious metal currency was born. In the beginning, copper mines, as an important strategic resource, were extremely valuable means of payment. Archaeologists discovered in Crete that there were The original copper coins minted by the Minoan civilization. The raw materials come from Cyprus, which is rich in copper mines, and it appears to be of a very international level. Of course, the introduction of precious metals never means the end of the history of shells as currency. People use it across a wide range of regions When trading, gold, silver, copper and iron with high net worth are naturally the first choice to increase purchasing power and facilitate transportation. However, within specific communities, shells are still an agreed daily means of payment. Especially in non-coastal areas, the value of shells increases with coastal mining. The decrease in miners has led to a reverse increase. Therefore, it was not until the development of horse breeding technology that the circulation area of ​​shell coins was further compressed. Due to the blockchain attributes from the beginning, shell coins are fully capable of spreading within the radiation range of their origin. It maintains meaning within. Because as long as there is the approval of the user, even game coins can have complete monetary capabilities. Shang and Zhou shell currencies from the 15th to 9th centuries BC. However, with the development of transportation technology and the lengthening of international trade, Shell coins were gradually phased out in many regions. First in the Eastern Mediterranean region, where the commodity economy was the most developed, and then in Syria, Mesopotamia and Egypt, which were closely connected with it. The mining and circulation of large amounts of gold and silver made it even more difficult. The value of copper coins quickly fell, squeezing out the last remaining remnants of shells in everyday life. 7-6 B.C.In the 19th century, the Lydians in the western part of the Asia Minor peninsula minted revolutionary round gold and silver coins. Within 200 years, this form was unanimously recognized and quickly spread among the two major groups, the Greeks and the Phoenicians. Through their transmission, it spread throughout the Mediterranean world, Egypt, the Black Sea basin and Mesopotamia. When the Persian army marched westward from the mountainous areas further east, they immediately took over this financial coinage system. By the 5th century BC, silver coins with stable quality had become the main object of tax collection by the empire. The Persians also used various means to accumulate large amounts of precious metal reserves in their treasury as reserves for issuing coins at any time. Although this process is still very crude and primitive, it has been used in financial operations for thousands of years. Lydian gold coins from the 7th to 6th centuries BC Athenian silver coins from the 6th to 5th centuries BC Silver coins from the Persian Empire from the 6th century BC Even in places where gold and silver did not circulate much, the decline in the value of copper coins alone was enough to popularize the metal currency. For example, in India, at least during the Mauryan Empire of Ashoka, square silver coins with local characteristics were issued. However, in border areas where the empire's control was weak, shells continued to be used as value carriers for small groups. When Mediterranean merchants from the Hellenistic era continued to arrive, the monetary system along the western coast was completely upgraded. But in the Bay of Bengal, which is densely covered with swamps and rarely touched by outsiders, shells still served as currency until the 19th century. During this period, they will become flexible and diverse means of transaction payment together with precious metals, spices or other commodities. As for extremely immoral slaves, they are also a circulating resource in this huge market. In more remote East Asia, metal currencies also appeared during the Zhou Dynasty. But at the same time, the phenomenon of shells as folk currency has always continued. The currency upgrade process similar to that in the Mediterranean and West Asia is happening again here. Because early copper coins were of high value, they were larger and did not need to be carried too much. However, as copper mines increased and a small amount of gold and silver were imported, copper coins gradually shrank and occupied the shell market. However, because the external communication channels were too narrow and a large amount of copper was prioritized for weapons manufacturing, the use of shells continued until much later. The round square hole coins designated by Qin Shihuang were a key step in upgrading the currency value. The large handfuls of copper coins connected with ropes are almost identical to the shell necklaces worn by ancient ancestors. Although the Qin State never eliminated shell currency, the impact of this choice lasted until the Qing Dynasty in the 19th century. The silver coins of the Mauryan Empire in the 4th century BC, the Seven Heroes copper coins in the Warring States Period, Qin Shihuang chose coins with round square holes, but failed to eliminate shells. At the end of the Middle Ages, the limited precious metal production was unable to support the development of the overall economy. The original driving force of the Age of Discovery was the joint treasure hunt between European royal families, nobles and merchants. They also soon discovered large areas of primitive economies using shell currency on both sides of the Atlantic. The Portuguese who landed in West Africa realized that tribes along the Gulf of Guinea used shells as a means of payment. Even the most economically developed Kingdom of Southern Sahara would agree to accept the shells sent by the Japanese. Although gold, weapons and saltThey all have circulation properties, but their weight and popularity are not as widespread as those of shells. Therefore, in the early trading station forts, a professional employee would be assigned to clean the shells. Then they combined weapons or luxury goods shipped from Europe in exchange for local gold and slaves. *** Merchants who are using shells in West Africa. The Portuguese used shells and other methods to exchange for a lot of West African gold. The colonists of Northwest Europe in the 17th century also discovered that the Indians in North America liked to use shells as currency. Despite being isolated from the world for nearly ten thousand years, they have also formed a characteristic economy similar to distributed accounting. As for South America, which had been previously conquered by the Spanish, shell payment was first eliminated due to the large-scale mining of silver mines in Peru. But the shell economy in North America lasted until at least the 18th century. Before members of the Indian economic circle recognized European gold and silver, they strictly protected their shell currency system and contributed a large number of expensive furs. Indians in North America also continued to use shells as currency. 3 The ultimate pressure in the modern world. Shell currency in West Africa and other places persisted until the 19th century. When readers see this, they may feel that the survivability of shell currency is very strong. Throughout history, it is not difficult to find that it is of great significance to certain places to maintain independent economic zones. However, due to the lack of reserves and other reasons mentioned above, shells are always at a disadvantage in the face of precious metals. These flaws are also the flaws of blockchain currencies in the early 21st century. Still taking Africa, which has long insisted on trading shells, as an example. Between the 15th and 19th centuries, the economic strategy of the local black kingdoms was to limit contact, export irreplaceable goods, and strictly prohibit European business groups from entering the mainland market. Of course, they are actually indispensable for the weapons and other goods imported by white people, but generally they can maintain this balance. However, with the advent of the more powerful British Empire, the past methods of dealing with Japanese, Portuguese and Dutch merchants gradually lost their effectiveness. West Africa has become an integral part of the transatlantic multilateral trade. The British can ship large quantities of shells at any time if they are willing. After the British gained advantages in the Atlantic region, they continued to influence West Africa through places such as Ghana's Gold Coast. The huge shipping capacity advantage of British sea power allows them to transport several meals of shells for trade at any time if they want. This weight is undoubtedly far greater than that of the medieval camel caravans and later the fleets of early adventurers. Therefore, no matter how exquisite the polishing skills of local local workshops are, they will always be defeated at the technical level. Secondly, when European and American countries banned the slave trade, the advantages of coastal tribes’ specialty products disappeared. As a result, the originally balanced trade suddenly became unequal. As a result, the shell currency was quickly defeated in a short period of time. The remaining craftsmen can only turn ""coin-making skills" into custom tourism projects, which continue to this day. In North America, the collapse of shell coins is even more unsuspicious. As early as the colonial periods of Britain and France, there were a large number of The natives gave up their original traditions and tried to integrate into the international world. That is to say, the shell coins disappeared from the coast in a short period of time and degenerated into a reserved item for trade between different tribes. TimeA time when everyone felt its value was too low, prompting the shell to continue to degenerate into the internal currency of conservative tribes such as the Iroquois. Finally, with the establishment of the independent United States of 13 states, the westward movement also completely replaced the original blockchain orphans. The abolition of the slave trade caused West Africa to lose its advantage. The shell processing industry finally changed from currency to handicrafts. The proportion of global currency transactions as of April 2019. Since then, the global monetary system based on the gold standard has gradually spread, and the value of precious metals has also been weakened. The shell at the bottom has no chance of turning over. However, in today's Papua New Guinea, cowrie shells are still legal tender in the eastern province of New Britain. But its symbolic significance obviously far exceeds its actual value. But you have to admit that as the first official currency, shells do have extraordinary tenacity. Looking back at this history of more than 5,000 years, people today can clearly understand the advantages and disadvantages of blockchain-like technology. The barbaric growth stage of high net worth involves a lot of risks in addition to benefits. The application of decentralized thinking is its core competitiveness that always attracts attention. But any currency cannot do without value endorsement, which is the most important reason why every country today has a central bank.
