Free chain mining

1.

In 2009, bencong invented bitcoin, and set that there are only 21 million bitcoins. By participating in the proction of blocks and providing proof of work (POW), he can get the reward of bitcoin network. This process is mining

the concept of "mining" comes from the existing concepts in our real economic life, such as gold mining and silver mining. Because minerals are valuable, it drives people to pay labor to dig

another important point of bitcoin mining is that the miners who participate in mining recognize the value of bitcoin, and some of them are willing to spend money in the bitcoin market. Therefore, the mining of bitcoin is meaningful

currency characteristics of bitcoin

1, decentralized

bitcoin is the first distributed virtual currency, and the whole network is composed of users without central bank. Decentralization is the guarantee of bitcoin's security and freedom

5, no hidden cost

as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay

6, cross platform mining

users can explore the computing power of different hardware on many platforms

2. Since there is no way to get active value, you can't mine, Digging a mine needs to consume an active one, which is worthy of specific mining. Go to the props merchant of each city to buy a hoe, and then go to the mine to attack with ordinary physics. The mine map http://tieba..com/f?kz=296198109 Method of obtaining active value 1) players above level 40 will be rewarded with 50 active value for each collection ring task completed. They can receive tasks all day on Sunday (they can receive tasks on Sunday first, Then you can get rewards at any time when you finish Cheng). The collection ring is changed from the original five times to ten times, and the rewards are more abundant. You can receive the task at the collection task releasing officer next to the Longcheng intermediate warehouse manager, and you can buy task items at a low price to complete the task at the task officer. 2) Fantasy defense active value reward defense task completion reward: 15 points in level 30-40 normal mode, 20 points in difficult mode; There are 25 points in common mode and 30 points in difficult mode; Grade 60-80: 35 points in common mode, 40 points in difficult mode and 45 points in incredible mode. Reward for the failure of the defense task: 8 points in the normal mode and 10 points in the difficult mode at level 30-40; There are 12 points in common mode and 15 points in difficult mode; Grade 60-80: 17 points in common mode, 20 points in difficult mode and 22 points in incredible mode. The task is collected from the envoys who defend the city. Level 30 and above can participate in the parallel world task activity value reward. Players of different levels can get different parallel world activity value tasks at Longcheng NPC's "captor Weixing" (coordinates 220, 98). Players can kill parallel world monsters and get normal falling objects when they finish the task. They can also get a certain activity value reward when they return the task, Each player can only receive a parallel world mission once a day. 38 ~ 49 level player sky spring's entrustment, teaches the variant spring spirit to obtain 15 points of active value reward; 50 ~ 59 level player tianfeng's entrustment, teaches the gate god to get 20 active points reward; Level 60 ~ 72 players are entrusted by the flower demon nest to teach the vine giant a lesson and get 25 points of active value reward; Entrusted by night shadow village, players above level 73 can teach ghost wolf · darkness and get 30 points of active value reward; 73 level and above player misty swamp Commission, teach water magic dog to get 35 points of active value reward; 4) In Pearl Sea area, 15 active points will be awarded after customs clearance. 5) Devil square, receive a warrior gift bag and reward 25 active points.

3. "Mining" in the blockchain is the process of bookkeeping. You can purchase computing power equipment, that is, "mining machine", to "mine" and get bookkeeping rewards
however, with the increasingly fierce competition in bookkeeping and the graal rise of dpos, ordinary computing power equipment has been unable to meet the needs of mining
it is necessary to purchase more professional mining machines or join large mines. Therefore, the threshold of mining is slightly higher
where there is demand, there is market
e to the increasing market demand for professional mining machinery, more and more chip enterprises increase investment in chip R & D, and start to develop mining machinery with higher computing power and lower energy consumption, so as to earn profits
when the currency price rose sharply in 2017, this kind of mining machinery was in short supply
as the level of computing power in the whole network is getting higher and higher, it is difficult for a single miner to seize the bookkeeping right and obtain bookkeeping rewards. Therefore, the way of combining a small amount of computing power and joint operation arises at the historic moment to improve the competitiveness of bookkeeping
the website established in this way is called "mine pool"
the profit model of the mine pool is to charge the handling charge. The more people participate in the mine pool, the higher the proportion of handling charge, the higher the income of the mine pool company
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

4. 1. Control
generally speaking, bitcoin and cryptocurrency tokens provide you with more control. You effectively cut the middleman between you and your money. No bank can decide how long a transaction will take and how much it will cost. You can also control where funds are stored and how they are accessed. Of course, control brings corresponding responsibilities
2. Affordability
since the middleman is not in the picture, you can save some transfer fees. Moving bitcoin from one wallet to another costs a negligible amount of money. It is cheaper for businesses to accept bitcoin payment than credit card payment
3. Speed
in addition to saving international transfer fees, you can also enjoy higher transaction speed. What does it take your bank a few days to do? Bitcoin can do it in a few minutes
4. Convenient
with bitcoin, online payment is easier and faster. If you want to donate or pay for something that will not be delivered, you do not need to disclose any personal details. Just send bitcoin to their wallet address
5. Security
it is safer for businesses to accept bitcoin than fiat money. When businesses accept credit card payments, they risk fraud and reverse payments. Bitcoin payment is irreversible, so there is no risk of reversal
6. Privacy
one of the main advantages of using bitcoin is that it provides privacy and relative anonymity. You don't need to provide any personal details to access the bitcoin wallet. All you need is a device to store it - even a piece of paper. Bitcoin transactions are only linked to your wallet address
7. Reliability
bitcoin network is essentially a point-to-point payment system. This allows you and you to remit money to anyone who participates in the party. You don't have to rely on the bank to do the work to make the transaction effective. In Ethernet, the risk of payment loss is small, which eventually makes it a more reliable way of payment
8. Investing in
bitcoin wasn't worth a lot of money ten years ago. Let's see where it has been since 2009. From a few dollars in December 2017 to nearly $20000. At the time of writing, it is now stable at around $6000. As more and more people adopt bitcoin, bitcoin will not be everywhere. Investing in it may be risky, but it's absolutely profitable.

5. I'm not sure about other things, but I heard that IPFs, a magic calculation of fire and thunder, is pretty good.
