Load the coin and go overseas! Over the past few months, this seems to be the most popular topic among the smart minds in the currency circle
indeed, after the relevant ban, the innovators of the currency circle began to participate in the research of "currency" trading and "agent investment and private placement" and other hedging means, and made great achievements. However, this has not restrained the pace of many exchanges and money circle tycoons moving overseas, and the Machiya houses in Kyoto, Japan, and the cryptocurrency company registration applications in Minsk (the capital of Belarus) have also gone up
It's just that what's going up in Kyoto is the local house price (including the price of a big guy's house); And Minsk rises, it is its high-tech park (HTP) the intermediary company that agent registers offersas soon as anything gets hot, the cost of all aspects will increase. So more intelligent people began to focus on Africa, an ancient and mysterious land
As one of the cradles of ancient human beings and civilizations in the world, Africa is also plagued by poverty and backwardness. Recently, this piece of land is being regarded as "the next blockchain center" by more people in the monetary circle. Many investors and entrepreneurs begin to shout, "blockchain related enterprises are constantly emerging here, and Africa, which is quite different from the traditional impression, may soon appear in front of people."people always believe what they want to believe, even ignore the facts. From the current point of view, Africa should have a long way to go from the title of "blockchain center". If you want to go gold panning, you must think twice
we analyze it from four aspects:
the concept of management department is rigid
Cape Town is the second largest city in South Africa, which is famous for its beautiful natural landscape and wharf
just recently, a "blockchain Research Institute" was quietly established in Cape Town. According to media reports, the blockchain research institute does not do academic research. Its main work is to provide training services related to blockchain technology to some local start-ups. According to its insiders, they not only provide training services, but also provide blockchain consulting services to enterprises
in addition, the blockchain Research Institute has also carried out close cooperation with local financial institutions, including the Bank of Africa, Standard Bank of South Africa, etc. Interestingly, some managers of these banks have received relevant training in the "blockchain Research Institute"
in fact, this blockchain Research Institute is a very common ecational institution, and it is profitable. Its teaching ability is questionable. More importantly, there is no university offering blockchain related courses on the African continent, and there is no corresponding supply of blockchain talents. The vast majority of the people still know little about blockchain
in developed countries, blockchain courses have been implemented in Colleges and universities. According to incomplete statistics, dozens of universities such as Princeton University, Tsinghua University, Stanford University, Copenhagen University, MIT, Imperial University of London, Cambridge University and New York University have offered blockchain courses
if ecation can't keep up with it and there is no large supply of talents, the construction of instry will be inadequate. For the road of blockchain in the African continent, talent is a top priority
worrying about infrastructure
when it comes to blockchain, mining is an inevitable topic. Mining requires a lot of power consumption. The S9 miner usually consumes 1350 watts of power ring operation, which is equivalent to exhausting the life of a hair dryer
However, the price of electricity varies from country to country e to different factors, including local natural conditions, development level of proctivity and relevant welfare policiesaccording to a research result of an organization, the cost of mining in Africa is the lowest, and the average cost of digging out a bitcoin is $4626. The rest were South America (US $5456), Middle East (US $6249), Asia (US $6378) and Europe (US $6695)
does this mean that digital currency mining can be carried out on a large scale in Africa
The Research Report "people, power, planet" released by the African development group tells us the answer from the side: in Africa, one out of every three people has no electricity. According to the total population of Africa, about 621 million Africans have no electricity. According to its development trend, it will not be until 2080 for Africa to realize the power popularization of the whole continent. In terms of grid capacity, sub Saharan Africa is about 90 megawatts, which is even lower than South Korea, which has a fifth of its population
although the electricity price is cheap, the future of blockchain's large-scale implementation is unknown when the backward infrastructure has not completely rid the public of the problem of power shortage

Let's suppose villagers Lao Wang and Xiao Li. Lao Wang borrowed some money from Xiao Li, who wrote it in an IOU signed by both parties. A few days later, Lao Wang denied the existence of borrowing money and claimed that Xiao Li forged the paper. Xiao Li can't argue because he finds it difficult to prove that Lao Wang actually owes him money
in this example, Lao Wang and Xiao Li are two nodes
now assuming the same scenario, there are many pairs of people trading with each other in the village. The only evidence for each pair is the IOU. If one party fails, it will be difficult to do so. Seeing this scene, the village head came up with a solution. He suggested using a common notebook for the whole village to record all the transactions. Due to the high prestige of the village head, the villagers unanimously decided to let the village head keep this important transaction book. Each transaction, the villagers go to the village head's home, let the village head witness and record, each transaction is written into a notebook, and then safely saved. That notebook can be called a database
because this notebook is very important, the village head locked it in the safe. However, there are always some problems. Sometimes, the village head will accidentally sprinkle ink on the paper, making some transaction records illegible. This is called a single point of failure. The thief knows that there is an important notebook in the safe of the village head's house. He tries his best to steal it. This is called hacking
until one day, the village head's son owed others a lot of money, so the village head secretly deleted his son's debt entry. In this way, the village head's son "does not owe money."
when the villagers knew this, they began to question the fairness and authority of the village head. So some people put forward a new idea:
abolish the power of the village head, which is called decentralization. Let all villagers keep a notebook, and the transaction records are copied and distributed, which is called distributed database. Therefore, if there are n people in the village, there are n notebooks, that is, n nodes. Every time there is a trade between any two people, all the people in the village get together and record it in their notebooks. And no one can cover the sky. This is called decentralization
they also decided that they would never delete the mentioned transactions from their notebooks, which is irreversible. For example, Lao Wang borrowed a sum of money from Xiao Li before, but in the twinkling of an eye, he wants to return the money. Then the transaction book will not delete the previous borrowing record, but write a new repayment record, so there are two records
next, let's try to break this rule. What if we bribe Lao Wang to change his notebook? It's not feasible, because the next time the villagers meet, they find that Lao Wang's notebook is different from everyone else's, so the villagers notice that Lao Wang may be engaged in an indescribable transaction, and decide to abolish Lao Wang's transaction record and kick Lao Wang out of the organization
What if you try to bribe all the villagers? It's too expensive
the characteristic of this model is that greedy people need to pay a lot to attack the rules. He will find it more profitable to follow the rules
a smart child in the village suggested that each transaction data be called "block" and linked into a "chain" in chronological order, which is called blockchain
the exchange I am familiar with uses the currency payment enterprise version, which is a digital asset security payment system. The general principle is to store the private key locally, bind the exchange's unique client with multiple encryptions, and the system itself does not save the private key, so as to prevent the possibility of digital currency theft from the source. It is also convenient to operate, with unified management of Multi Chain and multi currency and convenient reconciliation
hope to adopt.
