50 yuan for blockchain mining

1. Yes, now you can buy a miner to dig bitcoin
but what I want to emphasize is that bitcoin mining is now a very professional instry. Although ordinary people can dig, the cost is much higher than that of professional mining, so it's better to buy money directly.

2. blockchain is a new trend at present, and I am also a senior player. As for mining, you can't dig much if you buy a miner. If you want to join in a large mine, you must pay attention to bitcoin. Don't dig other coins. But there are also many problems. First of all, you have to determine the authenticity of the mine. Second, you have to mine without losing money. This thing is very deep. Generally speaking, the threshold for ordinary people to enter the blockchain is very big

3. Now there are two kinds of miners. One is to directly choose the mining machine with high income. For example, the income of the A9 is very considerable. It can earn about 620 watts a day, and the power consumption is not high. In this way, if the miner wants to start, it should be done as soon as possible. Only in the previous period can it achieve low cost and high benefit. There will be no such situation when the later period is stable. 2、 The miner doesn't have to pay attention to the current currency income. He only cares about the currency, waiting for him to turn over.

4. Absolutely false, only the ll sound makes a lot of money, there is no publicity everywhere. At present, the propaganda is to ask you to accept the offer. You can see that bitcoin is the first currency in the blockchain. Currency is the right of a national bank, and bitcoin is too harmful. All countries and banks are resisting it. From the current trend, the disadvantages of blockchain currency outweigh the advantages, but blockchain technology is still promising, but not currency.

5. How hot is the blockchain? Even my mother knows this word, and many people around me also ask me about it
in fact, their real idea is to know how to make money. After all, how much has bitcoin gone up in recent years when all kinds of information came out on the Internet, and to what extent has blockchain become popular today, Internet companies in all halls have joined in. As ordinary people, they also want to splash in this "pond"

so what is blockchain< In a broad sense, blockchain technology is to use blockchain data structure to verify and store data, use distributed node consensus algorithm to generate and update data, and use cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing paradigm to program and manipulate data by using smart contracts composed of automated script code
in short, blockchain is a decentralized distributed ledger database. Decentralization is different from the traditional way of centralization. There is no center, or everyone is the center; Distributed ledger database means that the recording method is not only to store the ledger data in each node, but also to share and the data of the whole ledger synchronously. At the same time, blockchain also has the characteristics of disintermediation and information transparency
let's give an example. For example, in our usual online shopping, after placing an order, our money will be transferred to the intermediary platform of the third-party payment agency. After the seller delivers the goods and the buyer confirms the receipt of the goods, the buyer will inform the payment agency to transfer the money to the seller's account
however, the transaction mode supported by blockchain technology is different. Buyers and sellers can trade directly without any intermediary platform. After the transaction between the buyer and the seller, the system publishes the transaction information in the form of broadcast, and all hosts receiving the information record the transaction after confirming that the information is correct, which means that all hosts have done data backup for the transaction. If there is a problem with the orders proced by this machine, its data information will not be affected, because there are countless machines backing up data at the same time
when it comes to blockchain, we have to mention bitcoin, as if you don't understand anything without putting the two together
in fact, although blockchain is a blockchain and bitcoin is bitcoin, most of the people concerned are
concerned about bitcoin, and not many people are concerned about blockchain. Even if he says that he is concerned about the chain, in fact, that is to make do with the excitement. What the other party is more concerned about is which kind of currency makes more money. How can I join in
in fact, what I want to say is that you don't have to catch up with every outlet. If you don't catch up with the stock market, we media, wechat business and artificial intelligence, so will the blockchain. New procts will soon replace it
What's the role of blockchain in making people so obsessed? Let's take the above shopping example to illustrate that the so-called bilateral transactions are not absent now, but they are both bilateral transactions. What if one of them does not deliver the goods to you after receiving the money, or if he does not accept the account after receiving the money
How can blockchain solve this problem
it's also a transaction, but in the process of transaction, everyone knows that the other party has given you the money, and you can't deny it. In the final analysis, it's a matter of credit value
what can blockchain bring us? Once there was such a news in the society that how to prove that your mother is your mother. Even if we have the ID card account book in our hands, we still need a government agency to identify it, which is cumbersome
with the help of the regional payment chain, we can establish credit with low cost through mathematical principles rather than centralized credit institutions. In this way, our birth certificate, household register and real estate certificate can be verified on the blockchain. Your mother is your mother's problem
another example is the food safety problem that has been implemented at present, and the rookie tmall Jingdong has started to use it. With the help of blockchain technology, a reliable mechanism has been established for all transactions, which enables procers, suppliers, processors, distributors, retailers, regulators and consumers in the food chain to obtain the source and status information of food at any time, so as to facilitate the tracking of contaminated food, accelerate the removal of problem food from shelves, and effectively prevent the spread of food safety problems
when consumers buy food, they can easily see where the food they eat comes from, how long it has been proced, and what fertilizer they have applied. For the arrival of blockchain, whether we are ready or not, we still have to see if we are not ready

6. Block chain is a public record of bitcoin transactions in chronological order. The block chain is shared by all bitcoin users. It is used to verify the permanence of bitcoin transactions and prevent double consumption
a block is a record in the block chain, which contains and confirms the transactions to be processed. On average, a new block containing transactions is added to the block chain by mining every 10 minutes
more can be found on bitcoin home.

7. 1. Build a payment system on the blockchain and mine CPU. 2. Graphics card is the most popular, most famous bitcoin, BTG, etc. 3. The mobile phone digs the virtual currency, and the mobile app digs out the currency, but it can't withdraw the currency temporarily, or there is no transaction value after withdrawing the currency.
