1. blockchain technology is considered to be the next generation of disruptive core technology after steam engine, power and Internet. If the steam engine has released people's proctivity, the power has solved people's basic living needs, and the Internet has completely changed the way of information transmission, then the blockchain, as a machine for building trust, may completely change the way of value transmission of the whole human society. In the past, relying on reputation, century old stores and authoritative institutions, blockchain has established a new way of trust by using technology, which can be quantified and realized from the perspective of technology. Therefore, blockchain has become the cornerstone of the next trust. The core revolutionary feature of blockchain is to change the backward credit mechanism for thousands of years
blockchain technology is the underlying technology of bitcoin. Bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted out, which was called blockchain technology or distributed ledger technology. It can be said that bitcoin is the first application of blockchain and will be extended to more and more instries in the future
bitcoin is the leader of virtual currency and has the reputation of digital gold. Its value lies in its network. We can connect to the global payment network in real time. It can send large or small amount of funds to any person, any place, any time, for any purpose, and complete the transaction without obtaining or sharing any person's private information. Using utomarket makes digital currency transaction easier.

2. 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<

3. The main difference between private blockchain and public blockchain is that jinwowo thinks that private blockchain only uses the general ledger technology of blockchain for bookkeeping, which can be a company or an indivial, enjoying the write permission of the blockchain. This chain is not very different from other distributed storage schemes.
4. Bitcoin is a kind of P2P virtual currency. Point to point transmission means a decentralized payment system. Bitcoin does not rely on specific currency institutions to issue. It is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole
P2P network to confirm and record all transactions< Bitcoin trading is carried out through bitcoin trading platform,
at present, the better bitcoin trading platforms in China are
okcoin, bitcoin China,
fire coin network, 796 trading network, etc. the capital of each company is different,
okcoin is based on Technology, and fire coin network pays more attention to user experience,
but in terms of professionalism,
okcoin is relatively good.

5. In general, the requirements for hardware architecture are not too high in the practical application of blockchain, but different applications have different requirements for hardware
for example, eurocrowdfunding is a new crowdfunding platform based on blockchain technology, which combines physical assets with digital currency. Each crowdfunding project will issue a different digital currency. Digital currency exists as an asset certificate and can be freely traded in the market.

6. In the blockchain system, the bookkeeper is selected according to a set of competition rules, and those who participate in the competition have a chance to win and be elected as Bookkeeper. Let's assume that this rule is a Rubik's cube competition, and the one who makes the Rubik's cube first will get the bookkeeping right. This reflects a feature of blockchain bookkeeping: decentralized bookkeeping. By playing Rubik's cube game, the bookkeeper is randomly generated to ensure that the bookkeeper is no longer a centralized organization.
7. Blockchain technology is characterized by anonymity, decentralization, openness and transparency. Blockchain is not a newly invented technology, but an integration of a series of technologies, including asymmetric encryption technology, timestamp, consensus mechanism and so on
taking bitcoin as an example, blockchain solves double spending and Byzantine Generals' problem through timestamp and proof of work mechanism, that is, it ensures that the same bitcoin can not be spent twice, and keeps consistency among all nodes in the whole decentralized blockchain network
the asymmetric encryption mechanism ensures the security of the private key, the timestamp ensures that the blocks are connected into chains in sequence, and the workload proof mechanism solves the problem of how to distribute 21 million bitcoins fairly in the decentralized system.

8. Xu Mingxing believes that with the rapid development of the current manufacturing instry, there will be more and more information physical systems in this field. These systems will proce a large amount of data, which is a great test for the transmission channels and processing equipment. Blockchain technology has a decentralized point-to-point communication mode, which can efficiently process the exchange of a large amount of data, Recing the cost of maintaining large data centers is the advantage of blockchain technology in the manufacturing field.
