Mining Blitz

1. 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. Take our life as an example. When you buy things on double 11, tmall's sales of more than 100 billion a day and huge digital computing are applied to cloud computing
there are also agricultural procts like rice, oil and so on
for example, vonetracer traceability system of wangchain technology is related to us.

4. Lightning bitcoin (LBTC) is a decentralized global value Internet transmission protocol, including point-to-point payment and trading platform. Any user who accepts LBTC protocol can use LBTC almost free to ensure the real-time and security of transactions. This concept has been seen in the official microblog of coin e before.

5. Depending on the specific era, the battle of Changping directly killed 400000 prisoners, and Xiang Yu, the overlord of Western Chu, killed more than 100000 prisoners many times. During the first World War, because it was a European war, surrender was not a big deal, so there were many prisoners of war, but they did not reach the level of one million. During the Second World War, Germany began to encircle and annihilate the Soviet army, and the number of Soviet prisoners of war did reach the level of one million, but not all of them were locked up in prison camps, Because many Soviet troops took up guns to attack the Soviet army. Of course, there were ethnic, political and other reasons. In the later period of World War II, the Soviet army also captured a large number of German troops and directly transported them to Siberia to dig mines and build railways. Many of them died. After the end of World War II, the civilians of some defeated countries were also exchanged between Britain and the Soviet Union. The Soviet Union directly adopted the policy of genocide and killed them, The Soviet Union killed the most people ring World War II, far more than Germany. As for the prisoner's camp, there will be no one with a million people. If there are too many people, there will be no way to manage it. However, there must be several prisoner's camps with a million people.

6. Yesterday, the instry exposed a big event - uniswap issued coins, and issued 400 Unis to all users who traded on it before September 1. The whole community was boiling, and Ethereum became congested again

the surprise that uniswap has brought to you is commendable, but its impact on the development of the whole defi and the overall market is more worthy of our in-depth analysis. Generally speaking, it will bring the following impacts to the whole Aftermarket:

1. Further popularize decentralized exchanges

uniswap's practice of benefiting the public will undoubtedly further enhance the status of decentralized exchanges in the hearts of all investors and popularize the use of decentralized exchanges, Promote more users from centralized exchange to decentralized exchange< All the initial liquidity mining pools opened by uniswap are related to Ethereum: eth / usdt, ETH / usdc, ETH / Dai, ETH / wbtc

it can be expected that with the opening of mining, a large number of eth will be locked, and this lock will last until November at least. If we think of the ongoing Ethereum 2.0 beacon chain, we will find that November is likely to be the launch date of Ethereum 2.0 beacon chain. At that time, a large number of eth will be used by the beacon chain to pledge mining.

7. Each step analysis:

1, open the ancient chariot to dismantle the other's home, another chariot can help Pangu, or can rush to the middle to grab the flag, if two chariots rush to the other's home together, someone must interfere with the other's flag raising

2. Pangu broke down his opponent's home and went to the middle to fight with the army to help raise the flag. If the double chariots successfully besiege the opponent's home and the expedition ends ahead of time, there will be nothing left and it will be meaningless

3. Seizing the flag is the first choice for stars. You can talk and laugh freely. If the chariot can conquer each other, it can be basically completed. The flag was raised successfully

4. If the flag is raised successfully, you can choose to encircle and suppress the local mining area (limit the other party's resources); Or guard your own mining area (increase your resource score); Or you can choose to go forward and demolish the opposite building. Eight minutes later, continue to come back for the flag

5. Repeat the idea of "three four"<

in this , killing people, demolishing buildings, demolishing cars and digging mines can score, and how to balance these small things depends on the commander's on-the-spot command ability
key words: form a team
at the beginning of the expedition, the other party may have just received the news that they are going to fight, and the participants are scattered, while the other party has formed two or three teams, Very likely to take a Blitzkrieg against the opponent, so that the opponent has little power to fight back
team 1: Flag grabbing group
95 + suque chariot driver (Shaolin) + 2 Emei + 3 thugs
team 2: Mining + mine protection group
90 + 2 thugs + Emei + miners
team 3: demolition group
95 + Pangu chariot driver (Shaolin or beggars' sect) + Emei + others
team 4: Mechanical Group...
team 1: Team 3: demolition group
95 + Pangu chariot driver (Shaolin or beggars' sect) + Emei others
team 4: Mechanical Group....
team 1: strive to form a good group before the battle starts, and the leader calls the group number

key words: chariot
chariot is particularly important in the war. Before the war, it is necessary to confirm whether the chariot driver is in place
1. Driver's choice: it's better to have more blood. It's suggested that Shaolin or the beggars' sect should teach if they can't. If there are too many Emei, it's also good to have more blood,
at least 8W of blood
2. For the identification of the opponent's chariot: see the figure below -

precautions:
① when you see the opponent's Pangu chariot coming to dismantle the base camp, you should immediately inform the guild
② when you see the opponent's rosefinch and white tiger chariot, you should immediately avoid being killed
③ don't worry when you see the green dragon chariot and Xuanwu chariot, especially the green dragon chariot, just go on

3. Selection of chariot: White Tiger conquers rosefinch, rosefinch conquers Xuanwu, Xuanwu conquers Qinglong, white tiger and rosefinch are better

key words: buff

buff means to get the following free or quasi free buffs before you start.
1. Lucky and happy three, 10 attributes
2. Master and apprentice of looting treasure, 5 attributes
3. Harmonious aura, 30 attributes
4. Get them from the Engineering Department of the guild. Generally, the senior 45-55 aura and strength care need 1 helping tribute
5 Moon cake and other
6.80 physical strength, 80 spirit, 80 power cooking procts, general 2 gold, a
7. Ruby essence, 36 yuan treasure, a 48 hour
8. ice watermelon, the basic attribute value +15%, need to consume tribute
of course, there are other things, such as A Zhu and Mu Wanqing task care, far away, need to do a certain relationship value
small note proposal: 1, 2, 3, You can get all 4, 5, 6, 7 and 8 if you have conditions. Generally, it can improve personal attributes by 20% - 30%. Although some caring effects disappear after death, some are better than none<

key words: Intelligence
intelligence work is very important, mainly aiming at the following aspects:
1. What is the total number of people on the other side? How many will take part in the war then? They usually ask the guild leader directly or check the number of officials online at the Luoyang guild
2. How many 95 + experts are there? Identify the enemy to watch out for
3. How many experts are there with more than 4 gems? Due to the limited number of Quanfu gangs, there are only about 20 gangs that are often enlisted, so it's OK to pay attention to them at ordinary times
4. How many Tianshan sects are there? If there is a senior, sneak attack mining or direct attack Huanglong can be careful, at the same time ready to senior see through baby<

key words: double open

since there are rewards for collecting tribute, if computer conditions permit, double open is allowed. If the trumpet is above 80, you can dig the mine first and then cooperate with the mine protection team. If it is below 70, it is recommended to quit the game after 5 minutes of mining and wait for 45 minutes to enter again to avoid sending points<

key words: surprise soldiers

ordinary surprise soldiers have special missions, such as high-level Tianshan Mountain, which seems to be unattended, but in fact they are ambush, or Emei, which has more than 60000 blood and high meat and high blood explosion, usually adds more blood, and obstructs the other party from raising the flag at the critical moment
of course, there are still many things to do before the war, and it's impossible to do everything. Most people just go into the replica to make a scene,

8. If I remember correctly, the World War 2 real-time strategy game didn't mine
either surprise or Blitzkrieg

9. Eve is a very free game. There are more than 100 kinds of ships in the game. You can do whatever you want. You can be a pirate. You can be a merchant. You can run trade. You can be a task party. You can dig tombs in archaeology.
you can be a dead space party. You can scan dead space. You can add an army. You can be a NPC. Pirates make money and fight with the army Grab territory. The battle of the Legion is not 15vs15. It's a battle of hundreds of people. You can also be the harvest team of the Legion. The anti harvest team is dedicated to maintaining the safety of the Legion system. Scientists engage in scientific research, miners engage in mining, and merchants engage in manufacturing. Too much to say no

in addition, the game is very cruel. All the items in the game are consumables, that is to say, if you accidentally blow up your boat, you have to buy one. If you blow up your escape capsule, you have to buy one. Your body will float in space, and of course you will be resurrected.
