Digital currency Tsinghua University

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin,

in essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information of bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

extended data

most blockchain public chains are limited by scalability. The biggest feature of blockchain technology is decentralization, which requires that all accounts in the network need to deal with the accounting process. Distributed accounting has high security, low misoperation rate, political neutrality and correctness

however, blockchain technology embraces these features at the same time, sacrificing scalability, unable to meet the personalized supervision, and slightly insufficient in protecting data privacy. Moreover, with the increase of the number of ledger, the interaction delay will increase exponentially, that is to say, the more ledger in the blockchain network, the higher the delay

China's top ten virtual currency trading platforms are bitcoin, okcoin, Huo coin, jucoin, yuncoin, BTCC, coin security, bitera and viabtc

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

as 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

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

according 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
