1. What is blockchain mining
there are two kinds of mining in the new era, the first is bitcoin mining. After each transaction occurs, it is not complete. The transaction data must be written into the database before it is established, and the other party can really receive the money. First of all, all the transaction data will be sent to the miners, who are responsible for writing these transactions into the blockchain to complete the mining and obtain profits
the second is to dig Shanzhai. Zero coin, Monroe coin, ether coin, Wright coin, bitstock and other "Shanzhai coins". After a miner is assembled, it is connected to the designated mine pool. According to the specific algorithm, it starts full load operation and completes a calculation cycle to obtain "one" virtual currency. Then put the "this" currency on the online trading platform to cash out
How can blockchain mine
at the beginning, bitcoin could be g up with the computer CPU. The founder of bitcoin, Nakamoto Tsung, g up the world's first creation block with his computer CPU. However, the era of CPU mining has long passed, and now bitcoin mining is the era of ASIC mining and large-scale cluster mining
if you want to be a miner, it's actually relatively simple. You can start mining by purchasing a special mining equipment. You don't need to do it yourself. In fact, the computer is performing specific calculations. For miners, you only need to ensure the power supply and network connection of the mining machine.

2. In order to understand the technical principle of bitcoin, we need to understand two important cryptographic techniques: hash code: it converts a long string into a fixed length string, and its conversion is irreversible, that is, it is impossible to guess the original string from hash code. Sha256 is mainly used in bitcoin protocol
public key system: corresponds to a public key and a private key, keeps the private key in the application and publishes the public key. When Party A transmits information to Party B, it can use Party A's private key to encrypt the information, and Party B can use Party A's public key to decrypt the information, so as to ensure that the third party cannot impersonate Party A to send the information; At the same time, when Party A transmits information to Party B, it is encrypted with Party B's public key and sent to Party B, and then Party B decrypts it with his own private key, so as to ensure that the third party cannot eavesdrop on the communication between the two people. RSA is the most common public key system, but the lliptic curve digital signature algorithm is used in bitcoin protocol. What's the difference between cash and bank account? Bitcoin is an electronic currency in BTC. In this article, it is also used to refer to the whole bitcoin system. Like opening an account in a bank, the corresponding concept in bitcoin is address. Everyone can have one or more bitcoin addresses, which are used to pay and collect money. Each address is a string that starts with 1. For example, I have two bitcoin accounts, and. A bitcoin account is uniquely determined by a pair of public key and private key. To save the account, you only need to save the private key file. Unlike bank accounts, banks keep all transaction records and maintain the book balance of each account, while bitcoin's transaction records are jointly maintained by the whole P2P network through a pre agreed protocol. How much money is in my account address? Although the current account balance can be seen by bitcoin software, unlike banks, there is no place to maintain the book balance of each address. It can only calculate the account balance in real time through all historical transactions. How do I pay? When I pay from address a to address B of the other party, the payment amount is e. at this time, both parties will announce the transaction information to each network node, telling address a to pay to address B, and the payment amount is e. In order to prevent the third party from forging the transaction information, the transaction information will be encrypted with the private key of address A. at this time, the network node receiving the transaction information can use the public key of address a to verify that the transaction information is indeed sent by address a. Of course, trading software will help us do these things, we just need to input the relevant parameters in the software. What will the network node do after receiving the transaction information? This is the most important part of the bitcoin system, which needs to be elaborated. For the sake of simplicity, only bitcoin protocol has been implemented. In the current version, each network node will save all transaction information synchronously. There are two kinds of transaction information in history, one is & quot; Verified & quot; The transaction information, that is, the verified transaction information, is stored in a series of "blocks". Each & quot; block" Is the previous & quot; bock" The ID of each block is the hash code of the hash code of the block and the new transaction information (see an actual block). The other category refers to those who also & quot; Unverified & quot; The transaction information just paid above belongs to this category. When a network node receives new unverified transaction information (possibly more than one), it can calculate the book balance of each address at that time because the node keeps all the transaction information in history, so it can calculate whether the transaction information is valid, that is, whether there is enough balance in the payment account. After eliminating the invalid transaction information, it first takes out the last & quot; block" Then, the unverified transaction information is combined with the ID, and a verification code is added to form a new "block". It needs a lot of calculation to build a new block, because it needs to calculate the verification code, so that the above combination becomes a block, that is, the first several bits of the hash code of the block are 1. At present, the first 13 bits need to be 1 (generally, the specific method is uncertain), which means that if the block is generated by enumeration method, the average number of enumerations is 16 ^ 13. Using CPU resources to generate a block is called "gold mining", because the proction of the block will get a certain reward, and the reward information has been included in the block. When a network node generates a new block, it will broadcast to other network nodes. However, this network block may not be accepted by the network, because it is possible that other network nodes have proced the block earlier. Only the earliest block or the block with the largest number of subsequent blocks is valid, and the remaining blocks are no longer used as the initial blocks of the next block. How does the other party confirm that the payment is successful? When the payment information is distributed to the network node, the network node begins to calculate whether the transaction is valid (that is, whether the account balance is enough to pay), and attempts to generate blocks containing the transaction information. When six blocks (one direct block and five subsequent blocks) contain the transaction information, the transaction information is considered "verified", so that the transaction is formally confirmed, and the other party can confirm the successful payment. A possible problem is that I will pay the balance of address a to address B, and at the same time pay to address C. If I only verify that the single comparison transaction is valid. At this point, my way of cheating is to generate six blocks including B to B and six blocks including C to C before the truth is revealed. Because I need a very long CPU time to generate a block, compared with the whole network, the probability of my cheating success is very small. What is the motivation of network nodes to proce blocks? As can be seen from the above description, in order to make the transaction information effective, the network node needs to generate 1 and 5 subsequent blocks to contain the transaction information, and such block generation is very CPU intensive. How to let other network nodes help to proce blocks as soon as possible? The answer is very simple. The agreement stipulates that BTC will be rewarded for the address where the block is proced, as well as the Commission promised by both parties. At present, the reward for procing a block is 50btc, which will be halved every four years in the future. For example, the reward will be 25btc from 2013 to 2016. Is the transaction anonymous? Yes, and No. All bitcoin transactions are visible. We can check all transaction records of each account, such as mine. But what's different from the banking monetary system is that everyone's account itself is anonymous, and everyone can open many accounts. In general, anonymity is not as good as it claims. But bitcoin has another advantage in doing black market trading: it can't be frozen. Even if the police trace a bitcoin address, there is nothing they can do unless they trace the computer used by the exchange based on the Internet address. How to ensure that bitcoin does not depreciate? Generally speaking, in the case of equivalent trading activities, the value of money is inversely proportional to the amount of money issued. Unlike the traditional money market, the central bank can determine the amount of money issued. Bitcoin does not have a central issuing institution. Only by procing blocks can we get a certain amount of BTC currency. Therefore, bitcoin's new amount of money depends on: 1. The speed of procing blocks: bitcoin's agreement stipulates that the difficulty of procing blocks is fixed at an average of 2016 every two weeks, about 10 minutes. Moore's law of doubling CPU speed every 18 months will not speed up the proction of block. 2. The number of rewards for block proction: at present, 50 BTC is awarded for each block proced, which is halved every four years. In 2013, 25 BTC is awarded, and in 2017, 12.5 BTC is awarded. Considering the above two factors, bitcoin's currency issuing speed is not controlled by any single node in the network. Its protocol makes the currency stock known in advance, and the maximum stock is only 21 million BTC

3. If you want to know what IPFs super nodes are, you need to know what IPFs cloud nodes are first.
each cloud node in the interstellar meeting mine pool is an independent operating identity. We have 20000 nodes around the world, distributed in Tokyo, New York, Seoul and other international metropolises, as well as Beijing, Shanghai and other first tier cities. The whole layout is that interstellar will arrange, manage and operate the mine in a unified way, and supervise and disclose the operation of the mine openly and transparently. The configuration of each node is 4-core CPU, 4G memory, 4T hard disk, and 10-50 megabytes of dedicated broadband
if you own a part of the mine pool and some nodes, the whole income of the mine pool will be divided in proportion to the number of nodes you own. For example, you buy a cloud server on Alibaba cloud, and then you use the cloud server to mine. In fact, you don't need to buy a machine and a broadband. You only need to buy a one-year service of Alibaba cloud server. If you use this service to run mining, the profits will belong to you. Buying nodes to participate in the mine pool is the same as buying Alibaba cloud services
that is to say, IPFs interstellar cloud nodes are charged annually. If you buy a cloud node, you can enjoy the profit of one year's harvest of filecion. IPFs will charge a 10% to 15% commission. The IPFs interstellar super cloud node is the cost of 10 ordinary cloud nodes, and naturally enjoys 10 times the income of ordinary cloud nodes. In addition, super cloud nodes will enjoy more discounts.

4. Based on the Coulomb earth pressure theory, the active earth pressure of retaining wall is assumed to be generated by the sliding wedge of filling behind the wall in the limit equilibrium state. The first-order differential equation of earth pressure strength on the retaining wall is established, and the exact solution is obtained The results are compared with the Coulomb formula and the experimental results. The results show that the resultant force of earth pressure under the three wall displacement modes is equal to the result calculated by Coulomb earth pressure formula, but the action points of resultant force of earth pressure are significantly different. Combined with engineering design, the size and distribution of active earth pressure on retaining wall and the value of action point are discussed, and some suggestions are put forward.
