Don't brush your face in mining

See a lot of people selling bitcoin mining machines, why don't they go mining? Do they make more money selling machines than digging bitcoin
On the gold road, the most profitable is the ticket. Those who dig money are all gold miners. Mining machine manufacturers are those who sell water and shovels on the way to gold mining. The so-called saying is that they have heard the news one after another, and they specialize in the technology instry. It's OK to do a good job in their own specialty. They can't earn any moneythe purpose of enterprises is to make money. Since selling mining machines can make money, why should they be involved in the mining instry. Wu Jihan in mainland China is worth tens of billions of yuan only by selling mining machines, and he is engaged in large-scale mining in many countries. It's also very limited. Since selling equipment can make money, why do you have to mine
another example is the e-commerce instry. I don't know whether it makes money or not, but I know that agent operation must make a lot of money. Now the hot small program, businesses through small programs to earn money, I do not know, but those who help develop small programs companies must make money
2. Such things are fake, so you should not easily believe what your friends recommend.
3. It's certainly not illegal, and there are many domestic mining machines on the market. For example, interstellar bit is a very good IPFs mining machine manufacturer
4. We know the process of information computing hash packing: transaction record, time, account number, last hash value. We also know that all calculation and storage need to consume computer resources. In Nakamoto's design, the completion of bookkeeping can be rewarded with bitcoin by the system, which is also the process of issuing bitcoin. Therefore, bookkeeping becomes mining
bookkeeping
because bookkeeping is a reward, each time you can add a certain number of bitcoin for yourself, so everyone is competing for bookkeeping, which of course leads to a problem: when there is inconsistency in bookkeeping, the system introces workload proof to solve the problem, and the rules are as follows:
1. In a period of time, only one person can succeed in bookkeeping
2. Obtain the unique bookkeeping right by solving the cryptography problem
3. Other nodes the bookkeeping results
but before the workload proof, The accounting node will do the following preparatory work:
1. Collect the original transaction information that has not been recorded in the broadcast
2. Check whether the payment address in each transaction information has enough balance
3. Verify whether the transaction has the correct signature
4. Package and record the verified transaction information
5. Add a reward transaction: add 12.5 to your address Bitcoin
if you succeed in competing for bookkeeping rights, you can get a reward of 12.5 bitcoin
workload proof
the hash value of the previous block and the current account page information will be hashed together as the original information in each bookkeeping. In order to ensure that only one person can keep accounts around 10 minutes, we have to improve the difficulty of keeping accounts. The results of hash must start with several zeros. In order to satisfy the condition, hash is to introce a random number variable
denoted by pseudo code:
1. Hash (last hash value, transaction record set) = 456635bcd
2. Hash (last hash value, transaction record set, random number) = 0000afd635bcd
if you change part of the original information of hash, the hash value will also change continuously. Therefore, when you run hash, the value of random number will change continuously, A random number can always be found so that the result of hash starts with several zeros. The node that finds the random number first obtains the unique bookkeeping right
verification
after the node successfully finds the hash value, it will broadcast and package the block to the whole network immediately, and the node of the network will verify it after receiving the broadcast. If the verification is passed, it indicates that a node has successfully decrypted, it will not compete for the current block, but will choose to accept the block and record it in its own account book for the next round of competitive guessing. Only the fastest decrypted block in the network will be added to the ledger, and other nodes will to ensure the uniqueness of the whole ledger
If a node has cheating behavior, it will cause the node of the network to fail the verification, give up its packaged block directly, and cannot be recorded in the general ledger, then the consumption cost of the cheating node will be in vain. Therefore, miners consciously abide by the consensus protocol of bitcoin system, and ensure the security of the whole system
it's like you go to the construction site to move bricks. After moving bricks for one day, the contractor asks you how can you prove that you move bricks for one day?

5. What is the traceability of blockchain
simply speaking, traceability is based on the decentralized technology of blockchain to realize the non tampering characteristics of data. By monitoring the proction and transportation process of crops, the data is uploaded and broadcast to the whole traceability chain, and then the anti-counterfeiting code is scanned and viewed
while dmtc agricultural traceability and vonetracer are all based on the traceability of commodities of blockchain

6. It must be in the real name
otherwise it is impossible to withdraw cash
if it is not in the real name
it is equivalent to digging in vain

7. Fake don't charge money, if more than 200 still use promotion? Everybody's hanging up. Let's just give it a dime a day
8. If you don't dig, it will appear. If you dig, it will also appear
9. 1. Dalaran - Transport Ogg - make airship to thorn Valley - ride horse to twilight forest - Chiji mountain - Burning Plain - cross from Blackstone mountain to scorching Canyon - finally run right to barren land.
2. Dalaran - Transport darkness - if you have ever been to alaxi highland, fly to alaxi Highland - run down to Wetland - lockmodan - barren land.
3. Hire someone to pull you.
2 Run the second route by yourself
remember to fly
you can find 2 DK to pull it to you. There are assembly stones in the barren land, and all the flight points of DK are open
