1. blockchain platform, do you want to see blockchain information? Here is Amway password finance, general chain circle, coin circle, DAPP and other information.
2. I met a hacker
there is no way to find out the theft, just like where the blackmail virus is and who blackmailed it is still a mystery
the nature of bitcoin is that it cannot solve cases
bitcoin (bitcoin: bitcoin) was originally a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals.

3. The price of bitcoin has gone up abruptly, and the old miners who left the mine have begun to return. Many new people have also poured into the mining instry. However, the price has gone up, and the difficulty of mining bitcoin is also rising. How can we make money from mining now
- - talking about the mining cost of bitcoin -
the first thing to consider is the cost if you want to make money. If the profit is greater than the cost, it is worth doing. We all know how much bitcoin costs, so let's calculate the cost
1. Mining machine cost: the "number" of bitcoin is a problem-solving process, which can't be calculated by human brain alone. Therefore, mining people need to buy mining machines and keep calculating. The more mining machines, the stronger the computing power
2. Electricity charges: mining machines are big consumers of high power. How much electricity does it consume? Let's put it this way. At present, the electricity consumption of bitcoin and Ethereum mining has surpassed Jordan, Iceland, Libya and other small countries, ranking 71st among all countries and regions in the world. You want to cry when electricity is expensive
3. The rent of the place where the mining machine is placed: because the mining machine consumes a lot of electricity, the power supply load of ordinary residential buildings can not be guaranteed at all, so the mining must rent a commercial site separately, and the rent is much more expensive than that of ordinary residential buildings
4. Operation cost: in order to ensure the computing power, the high-power mining machine needs to work 24 hours, which requires someone to maintain it at any time. When the mining machine is in trouble, the cost of hiring someone is required; At the same time, the mining machine is very delicate. If it is too hot or too cold, the vegetables will be stopped. Therefore, the measures of cold air and cold water insulation are needed to help the mining machine run. This is another expense
5. Mining machine update cost: because bitcoin is becoming more and more difficult to dig, the machine that was able to dig a month ago may not be able to dig anything today, and the market will also launch mining machines with greater computing power. The original mining machine is not worth money immediately. If you want to maintain computing power, you need to buy mining machines again
the above bitcoin mining costs all have a marginal effect, that is, the larger the volume is, the lower the corresponding cost will be. Therefore, some super large mines have been built
bitcoin g in the mine will enter the mine pool and be distributed by all participants. Large mines will be built in places where labor and electricity are cheap, such as Venezuela, the legendary miner's paradise, or Iceland, where the climate is favorable and electricity is cheap
as for the cost, everyone will be different. Let's take a look at an average: in 2017, according to the data of elite fixtures, a research institution, Venezuela is the cheapest of 115 mining countries, which is 513 US dollars, while South Korea is the most expensive, which is 26170 us dollars
China's mining cost is US $3172, which is relatively low among 115 countries. However, the cost is an average value. Large mines with low electricity prices must be much lower. If you are a lone ranger, the cost will rise sharply
in a word, if you really want to make money by mining, first of all, unless you are rich enough to build a mine with thousands of machines, you'd better join a mine to dig together. Although you have to share the money, it's still appropriate in the long run because it can greatly rece costs and improve computing power
secondly, whether you dig by yourself or join the mine, you must choose the place with low electricity cost, and the city with abundant hydropower resources is preferred, because hydropower is the cheapest source of power generation in China at present.

4. In January 2013, Avalon released the 60g / s miner specification and accepted the booking. In January 2013, Avalon delivered the world's first commercial bitcoin ASIC miner, and Jeff garzik, the core developer of bitcoin network, was fortunate to be the owner of the first commercial ASIC miner.
the most difficult mining problem is 0. At the beginning of 2013, the computing power was about 2p, and now it has reached 100p

5. How can I not show you my mother but still prove that my mother is my mother
zero knowledge proof is a technology that the verifier can make the verifier believe a certain conclusion is true and credible without providing the verifier with the information itself. At present, the anonymous transaction of zcash, a digital asset with outstanding anonymity, is realized by "zero knowledge proof"
for example, a has to prove to B that he has the key to a room. Suppose that the key can only be used to open the lock of the room, but no other method can. At this time, a can choose to give the key to B, and B can use the key to open the lock of the room, so as to prove that a has the correct key of the room
or a opens the room with the key, takes an object out of the room and shows it to B. B knows that the object is only in the room. The principle of method two is zero knowledge proof
zero knowledge proof can prove that I know the secret without disclosing the information itself, and can effectively solve many verification problems.

6. It's very simple. It can be sold directly in the legal currency trading area
7. Beginners, I want to know more about the origin of the predecessor of bitcoin
8.
Recently, the U.S. Supreme Court said in a lawsuit that with the growth of time, people's views on money will change greatly, or bitcoin will become a form of compensation for employees one day in the future. It is understood that the US Supreme Court said for the first time in its ruling the existence of bitcoin
On June 21, the Supreme Court of the United States made a ruling in the case of Connecticut central Co., Ltd. the dispute involved in this case is whether the recognized stock option can be taxed in the same way as money as a way of compensationit is understood that the subsidiary of Canadian national railway company lost the lawsuit at the beginning, and the district court and later the court of Appeal ruled that the tax on stock options was based on the US tax law
However, according to the opinion released on Thursday, the US Supreme Court's decision on lease out determined that the shares would not be included in the monetary reward, and the case should be "further litigated in accordance with this opinion".
