How the block chain will change the world - you know the first article that the block chain should read

The future has come, but it's just not yet popular
Imagine we return to the gold standard in the world, then the amount of gold everyone have recorded in Alipay, we buy things and transfer through the gold to pay treasure, while physical gold we have hidden in the one who could not find a place.

This is a digital currency to describe for us the world, there is a kind of goods do not rely on the national sovereignty (here is gold) acting as the general equivalent, you will find that the general equivalent is not important what the history also had a silver shell equivalents even act as general situation, of course, it can also be is bitcoin, what really matters is the general equivalent to being accepted.
But the digital currency of the world is still a little different, in the digital currency in the world, Alipay does not exist, but there is a set of system, it does not belong to any person or company, jointly safeguard and control by most people, can be free to help us record assets and transactions, and never make mistakes, also cannot be attacked. This system is a block chain.
How can someone accept bitcoin?
Ask this question. Obviously, you haven't accepted bitcoin yet. It's not surprising that most people in the world don't accept bitcoin, but of course, some people choose bitcoin to accept bitcoin, for example, Microsoft Corp accepts bitcoin payment. At present, the total value of bitcoin is over $10 billion, and the price of a single bitcoin is about 3800 yuan.
Take now the degree between bitcoin is not overnight, in fact from bitcoin available up to now nearly 8 years of experience, the first bitcoin transactions in 2010, when a person with ten thousand coins to buy a pizza (now this is history the most expensive pizza), so bitcoin has a gradually accepted process, so the right question is, what is the promotion of a bitcoin accepted?
Obviously, the world did not initially bitcoin, bitcoin process known as mining, you can imagine it as gold mining. But bitcoin mining is a competition maths process, the system will all mining computer is a math problem, who first made this problem, who will get a bitcoin. The main factors influencing the mining output is considered, the higher the probability is dug machine bitcoin is bigger.
As gold mining bitcoin mining also need cost, power consumption and wear with ordinary computer hardware, now mining, resource consumption is about ten times the value of bitcoins dug up, so I want to dig through the rich buddy can wash sleep. Most of mine real professional are built in the hydropower station next to the low cost of energy, and the hardware and software optimization, more details about mining, can refer to this article.
Back to our question, how is bitcoin popular? The answer is that the efficiency of different mining period is different, in the early in the mining machine, the competition is relatively small, easier to dig bitcoin, of course this time bitcoin is not worth the money, early participation in mining are some geeks, they usually have the expected that bitcoin will in the future the more popular.
Circulation itself will bring value. In our initial gold case, actually, we hide gold and do not affect people to use electronic gold to trade, that is to say, we all value the value of gold, but the value of circulation as a carrier of value. From the angle of economics, mining supply is relatively stable, wider circulation means more people and scenes of bitcoin, but the increase in demand will push up the price of bitcoin.
That is to say, if you think bitcoin will be more popular, bitcoin prices are expected to rise, so there will be more people involved in mining, there will be people in the speculation, in general there will be more and more people involved, the process and the promotion of bitcoin prices, the formation of a the positive feedback loop, early participants have also benefited from bitcoin.
Of course, the real situation is more complicated, another important factor is that people need to constantly develop bitcoin payment scenarios, let more merchants to accept bitcoin payments, so as to truly promote bitcoin as a currency, but in fact, the key concept, let more people understand and accept bitcoin and digital currency.
No Alipay, digital currency to be recorded?
Here we need to explain the relationship, the block chain and bitcoin mentioned above, bitcoin mining is a process of competition mathematics calculation, in the design of the system, when bitcoin is dug, and will produce a block called things, each block will be recorded from a block to produce all bitcoin transactions at present.
In addition, each block has a head and tail, its function is through the principle of cryptography, connect the adjacent blocks, forming block chain, to achieve the effect, if a block content has been tampered with, the conflict will be adjacent to the block, which was found.

The design mechanism of block chain is only the longest chain is effective, if there is a bad node wants to tamper the blockchain content, it can't change a single block, only to produce false new blocks, which requires all other nodes and the whole network confrontation, so if this node has more than all 50% operation ability can be realized
