ICBC block chain mining 2020

1. 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.

2. It's about making money;, However, who knows! Whose money do you earn? If you don't think about it, how can blockchain financial disk make money?

3. In the big bear market in 2019, there is not much money making effect, and most of the high-yield ones are capital stocks

4. BTD is the most popular

Suppose you understand the blockchain. To put it simply, the blockchain generates a new block every ten minutes to store all the transaction information in the blockchain. This block is equivalent to a network account book, which correctly time stamps all the transactions of the whole network in the past ten minutes. The question is who will build it? The "miner" on the blockchain is to compete for the bookkeeping right of a block in the past ten minutes. The rule of competition is to solve the sha256 problem while correctly bookkeeping. Who can prove that his computer has the fastest computing power can compete for the legal bookkeeping right of the block in the past ten minutes. This is the "mining" process. In the bitcoin blockchain, miners who dig mines can get certain bitcoin rewards. Therefore, miner's more essential function is "bookkeeper"

in his bitcoin white paper, Nakamoto describes in detail the process of establishing the credit system:

Step 1: in order to make the whole network recognize effective, every transaction must be broadcast to each node (node: miner)

Step 2: each miner node should correctly stamp each transaction in the ten minutes and record it in that block

Step 3: each miner node should compete for the legal bookkeeping right of this 10 minute block by solving the sha256 problem, and strive for the reward of 25 bitcoins (50 bitcoins every 10 minutes in the first four years, decreasing by half every four years)

Step 4: if a miner node solves the ten minute sha256 problem, TA will publish all the time stamped transactions recorded in the ten minute block of TA to the whole network, which will be checked by other miner nodes in the whole network

Step 5: other miners in the whole network check the correctness of the block's accounting (because they are also stamping the time stamp for accounting, but they do not compete for the legal block's accounting right, so there is no reward). If there is no error, they will compete for the next block after the legal block, thus forming a single block chain of legal accounting, That is the general ledger of bitcoin payment system - blockchain

generally speaking, each transaction must go through six block confirmations, that is, six ten minute bookkeeping, before it can be recognized as a legal transaction on the blockchain. The following is the accounting format of bitcoin:

so the so-called "bitcoin" is such a billing system: it includes the owner using the private key to make an electronic signature and pay to the next owner, and then the "miners" of the whole network stamp the account to form a blockchain Network)

if you want to learn more about blockchain information, it is recommended that you use Baijia, mustard circle and other popular B circle media. The amount and richness of information are more and better than those on the general network.

6. Of course,
with the development of
blockchain,
digital currency
has been widely recognized, and more and more people are engaged in mining.

gym mining machine is recommended, with more advanced intelligent technology.

7. Sober up, China's laws and regulations do not allow investment in blockchain.

8. 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.

9. It's a bit late to dig. It's too expensive,
