Transport BTC

1.

No matter what form or state money exists in, it is something that everyone likes, and it has been like this from the beginning. When people establish the concept of private property, they proce the general equivalent as the certificate of exchange. And this kind of equivalent from the beginning of the shell, and then to copper, silver, gold, paper money and so on, and even a located in the Western Pacific Carol islands Yapu island using stones for trading

therefore, people who do not know much about bitcoin are advised to enter the market carefully. Bitcoin is not a hedge. Its price fluctuates greatly. People who speculate in bitcoin may get rich overnight or become poor overnight. And many countries do not recognize the legitimate utility of bitcoin, and some countries even explicitly prohibit the use of bitcoin. The above personal opinions are welcome to be criticized and corrected. Agree with me, please click like before you go, thank you! Like me, please pay attention to me, thank you again

3. Tell you what blockchain is and what can it do

what is a blockchain? How does it work

bitcoin has become the trend of modern Internet, followed by blockchain. It is said that blockchain technology will lead to fundamental changes in Internet operation, enterprise operation and everything else

but what is blockchain? Most of us don't know much about blockchain. If you want to understand blockchain, you can read this article carefully

what is a blockchain? In the simplest terms, blockchain is a distributed ledger

to understand what this means, let's first look at its opposite: a centralized ledger. Because blockchain technology starts from finance, we will also use the bank as an example

the following is the process of our bank debit card transaction:

you can buy goods by swiping your card in the store

the merchant sends the bill to your bank to get the agreed amount

your bank will verify whether you are likely to authorize the purchase

banks remit money to businesses

finally, the bank records this information in its ledger

there are a lot of technologies involved here, but basically that's it. The last step is important - the bank keeps track of all transactions made by the customer. This ledger goes all the way back to the first transaction the bank made

the ledger is kept, maintained and supervised by the bank. You can read it in your online bank account, but you can't change it. The bank is in full control. If it decides to make a change, there's nothing you can do

it is crucial that if hackers can access the bank's ledger, it may lead to many problems. They can change the account balance to make it look like some transaction never happened, and so on

that's why distributed ledger is so cool

if the bank operates on a distributed ledger, each member of the bank will have a of the ledger. Whenever any member of the bank makes a purchase, they will tell all other members of the bank

each member validates the transaction and adds it to the ledger (the added record is called a "block"). This has some important benefits because there are no centralized permissions to manipulate records. Hacker access to one ledger won't be a big problem because other ledgers can easily verify it

on the other hand, it requires a lot of work. In short, the second system is blockchain (at least in the financial scenario)

as mentioned above, blockchain is a decentralized transaction list. If I send Xiaoming two bitcoins, I will send a message to everyone in the network, saying "I am sending Xiaoming two bitcoins", and they will record the transaction<

bitcoin and blockchain

let's take bitcoin as an example to illustrate

bitcoin transaction

but the transaction must be verified. This is where blockchain technology has become a bit more complex. Each bitcoin wallet (which we will complete in one second) has a public and private key

you use your private key to send transaction requests to other members of the network and confirm that you have cryptocurrency in your account. If they do, they allow transactions to register on the ledger

the mechanism of public / private key system is very complex, but it comes down to that every transaction is verifiable and secure< However, the computing cost of the whole system is very high. Everyone who updates the ledger needs a lot of authority to validate transactions and modify the ledger. This is where mining comes in. People who verify and modify use their own computing resources, and each time they get a small transaction fee

and they're using a lot of electricity to do it

in this way, each transaction will be verified and added to the ledger, and the person who performs the verification and modification will be paid. This is a reasonable system

at the same time, it is also very safe. To change a single block, you have to change each subsequent block. After all this is done, validation will fail because other copies of the chain will show someone tampered with one

how to define blockchain is a difficult problem

although the mechanism behind blockchain technology is not always intuitive, it seems that it is not too difficult to explain what blockchain is. But what we're describing here is the traditional definition

we can use this special type of blockchain for a wide range of applications;, Such as cryptocurrency, sharing medical information, sending security messages and so on. But more blockchain like technologies are being developed for other uses

for example, companies may use internal blockchains to manage problem tracking in software. Each block in the chain may represent a problem, and users can publish updates to the network. But is this a blockchain? In this case, the ledger is not public, it is only visible within the company

some people will say that this is not a blockchain

other blockchain like technologies are not encrypted. Are they still blockchain? What if it's centrally managed but uses other blockchain features? What defines the lowest level of blockchain technology? There is no consensus on these issues

what is a blockchain wallet

we usually hear people talk about bitcoin wallets, Ethernet wallets and other cryptocurrency specific wallets. But wallet technology can be used in any system that uses blockchain

a wallet is the software or hardware that "saves" your cryptocurrency. But it doesn't really have anything, it's just a place to store public and private keys. This information allows you to access the currency shown in the public ledger

the wallet is the only record of the key. So if you lose it, you will no longer be able to access your cryptocurrency

in the future of blockchain, how will it change our lives

one important thing about blockchain is that it is a public resource and no one really owns it because everyone owns it

blockchain is more than science fiction. We don't need to understand the mechanism behind this technology, but you need to understand that it may completely change our lives in the next 20 years

that sounds bold, but remember, 20 years ago, we were browsing the Internet on Netscape, using the most advanced Motorola flip phone, and buying our first DVD player. At that time, if we imagined that the computer could be held in our hands, and that we could buy a car, pay for money and watch movies on it, it would be considered a fantasy

although the impact of blockchain may not be as obvious as the Internet or as tangible as mobile phones, blockchain will effectively solve many troubles in daily life. For example, intermediary entrapment, transaction delay and so on. In our present life, middlemen can be seen everywhere. We take it for granted that they are a part of our life. If one day, these intermediaries no longer exist, you will find that the world will become a different one

imagine that by 2040, blockchain may become a mature and widely used technology. One day, you can't do without blockchain, just as you can't do without the Internet now, you will be surprised that this decentralized accounting technology has become a part of your lifestyle<

4. How can dpos balance the advantages of centralization and decentralization
share authorization certification mechanism, dpos for short, is similar to the voting of the board of directors. The coin holders cast a certain number of nodes to verify and account on their behalf. In order to encourage more people to participate in the election, the system will generate a small amount of tokens as a reward. Bitstocks, diandianbi and other digital assets use this method
dpos is a bit like the parliamentary system or the people's Congress system. If representatives can't perform their ties, for example, when it's their turn to keep accounts, they will be removed and the network will select new nodes to replace them
each client of dpos has the ability to decide which nodes can be trusted. Compared with pow (workload proof mechanism), dpos greatly improves the ability of blockchain to process data, and can even achieve second arrival. At the same time, it also greatly reces the cost of maintaining blockchain network security, so that the transaction speed of digital assets is close to that of centralized settlement systems such as visa.

Moving bricks is a Chinese word, which originally means carrying bricks. In Internet language, moving bricks is extended to hard work, repetitive machinery, and not much money. In some dialects, it refers to playing mahjong. In commercial trade, it means earning a price difference, buying by the owner and selling by the west, and it also means moving money. Originated from internet post bar

this word is a Chinese word, which first refers to carrying bricks. In some local dialects, it also means playing mahjong. In commercial trade, it also means to earn a price difference, buy from the owner, sell from the west, and move money

extended materials

describes working hard and not making much money, but having to do it

has different meanings in different contexts:

1. For example, in various online games, players spend a lot of time and energy to earn

For those who are engaged in chemistry, biology and other experimental subjects, because the process of doing experiments is relatively boring, "moving bricks" is often used as a nickname for doing experiments

3. This entry has a special meaning in "ngeons and Warriors". The brick here refers to "magic brake stone", which is the item needed to open the of "Antun" team. Because of its high value, many players get this item at "grandi power plant" for selling price

Generally speaking, programmers (coders) write tedious code, which is similar to moving bricks, and is often ridiculed by programmers

When chatting on the Internet, it's not convenient to disclose one's career, so it means to go to work and leave temporarily instead of chatting

6, move brick, in the network post bar, also have the meaning of transfer post

6. I know what you mean. You want to move bitcoin back and forth to make a difference. I just went to this website to see that the website does not accept personal accounts. It must be the bank account number of the enterprise. It also needs business license and other documents. It needs to be verified by the website before email activation. The proceres are very cumbersome. I've been watching it for a long time, and I've got a headache.
