this is mainly e to the 51% attack, because before some of the world's well-known mines, e to the low rate and convenient use, many miners went to those large mines to mine. As a result, the computing power of the mines soared, approaching or even exceeding 51% of the global computing power many times
bitcoin community has also raised a big discussion about 51% attack for many times,. The mine pool operators also called on the miners to move to other mines in a responsible manner, and finally 51% of the attacks were solved. Many of China's miners have moved to fish ponds
most of the new miners have joined the fish pond because they don't know about the global mine ponds, and many of the previous mines have died e to poor management
2. In fact, people will not let such a thing happen, because once someone controls 51% of the computing power of the whole network, the security and non tamperability of the system will be invalid, then the decentralization system of bitcoin will collapse, and the price of bitcoin will plummet or even return to zero, which is bad news for the participants of the whole network. Therefore, we will spontaneously control the distribution of computing power in the whole network, so as not to let one company dominate. Even when many people find that the computing power of a certain mine is too large, they will take the initiative to withdraw from the mine. Now the most powerful
mining pool in the whole network accounts for about 25% of the whole network.
3. The original intention of Nakamoto's design of bitcoin is to build a point-to-point trading network that is decentralized, transaction information can not be tampered with, and the total amount of money is constant, so as to solve the problems of excessive issuance of legal currency and inflation
this is the value of bitcoin's initial design, to keep the purchasing power of money
But later, the development of bitcoin went against Nakamoto's idea. In the past nine years, the price of bitcoin soared by millions of times, creating countless myths of sudden wealth and driving another instry mining
the value of bitcoin has become a tool for "sudden wealth". More and more people join the bitcoin network, hoping to achieve financial freedom. Digital cryptocurrencies such as bitcoin have become investment procts, like diamonds or gold
by purchasing bitcoin, people can achieve the purpose of wealth appreciation and asset preservation in many troubled areas. At the same time, many people make use of the fluctuation of bitcoin price to speculate, such as moving bricks, making bands and so on
another important value of bitcoin can not be ignored is blockchain, the underlying technology of bitcoin. Because of the popularity of bitcoin, many companies and indivials begin to pay attention to blockchain, and constantly try to use blockchain technology to change the existing business and create new value. It is with the help of bitcoin that blockchain has achieved such rapid development
bitcoin is also a great social experiment for all mankind, which promotes the reform of the financial instry and gives many original things a new perspective
4. Bitcoin is a kind of network virtual electronic currency, and its price has experienced roller coaster like ups and downs. It has no physical support, to put it bluntly, a string of computer code. Personally, I think this is a very unreliable thing. The Internet bubble is very big. In November 2013, the price of bitcoin once reached a high level of 8000 yuan / piece. Subsequently, the central bank, together with five ministries and commissions, issued the notice on preventing bitcoin risks, and the price of bitcoin plummeted. Now the price of bitcoin is more than 2300 yuan / piece
Jingxuan finance didn't you send a lot of articles a few days ago. China is now investigating bitcoin. Crash
5. Bitcoin cash will not have 51% computing power attack. In theory, 51% computing power attack exists, but in practice, it is difficult to work. The reasons are as follows: at present, no single miner can account for more than 50% of the whole BCC network; 51% attack is a kind of technical activity, which is difficult to operate; The cost and benefit of 51% attack are asymmetric, and 51% attack will lead to double spending of transactions. However, most of the trading platforms have implemented strict real name authentication mechanism, which can not be realized in time; Once a miner has the ability to launch a 51% attack, supporters of other large blocks will switch their computing power to Bcc to prevent the occurrence of 51% attack; 51% of attacks will cause temporary confusion on the network, but it is not fatal, and will make the attacker become infamous.
6. Gemstones can be obtained by mining. There are nine colors of jewels: red, orange, yellow, green, green, blue, purple, black and white. Except for black and white gemstones, other gemstones can be excavated in Taoyuan Village and other countries' mines. Qin: Ruby Zhao state: Orange Ruby Chu state: Topaz Yan state: Emerald Qi: sapphire Korea: sapphire. Black and white gemstones can be obtained from Luoyi mine. It has the following functions: synthesis of seven color gem, synthesis of night pearl and inlay of seven color gem. The synthesis of seven color gemstones needs seven colors of red, orange, yellow, green, cyan, blue and purple and 1 million yuan of money; To synthesize a night pearl, we need red, orange, yellow, green, green, blue, purple, black and white gemstones and 2 million yuan of money; A wedding ring inlaid with seven color gems needs a wedding ring, seven color gems and a million yuan of money.
7. I think it should be treated conservatively. My dad's experience has taught me what's the best. Find a famous doctor, traditional Chinese medicine, to open a suitable prescription, to insist on eating, can't because feel no effect, or think that after CT examination and a small step and give up taking traditional Chinese medicine. The adjustment of traditional Chinese medicine is a process. It's important to insist on it. Traditional Chinese medicine is not so fast in righting. There may be aggravation in the middle, but don't worry too much. Also, do not chemotherapy, eat Chinese medicine is not very toxic chemotherapeutic drugs, if the kind of strengthening the body and eliminating evil, improve the resistance of the kind of best.
