Blockchain usage
what is distributed and decentralized? Take marriage registration as an example. In the past, when two people got married, they had to go to the Civil Affairs Bureau to go through the formalities, and then enter the information into the computer before they could finish the legal process. What if we use blockchain technology? As long as two people agree to get married, and then release a message in the circle of friends, the process of marriage is completed, and there is no need to go to the Civil Affairs Bureau. Your friends are common witnesses, they may be distributed all over the world, but their mobile phones will help you record the information and tell others who want to know
if you want to hide the marriage information, you used to just modify the records on the computer of the Civil Affairs Bureau, but now you have to modify the records on the mobile phones of all the people who know the truth at the same time. The more people who know the truth, the less likely they are to modify it, so it is an impossible task. This is distributed and decentralized
deepen the understanding
on the network, every once in a while, a block will be generated. This block is equivalent to a network logbook, which is used to record the relevant information that happened in a period of time. When the logbook is full, a new logbook will be generated. Once the information is recorded, all participants will be informed, and everyone's logbook will be updated synchronously
these logbooks are finally connected in series, which is blockchain technology. Because of the use of cryptography technology, if someone wants to tamper with the message unilaterally, through the verification of blockchain algorithm protection mechanism, if the time point is not right and the associated information is not right, other people will not update their own record book, and the information will be invalid
therefore, compared with the traditional information storage technology, blockchain technology is more secure, transparent and irreversible
concept differentiation
blockchain is not equal to bitcoin, it is just a kind of underlying technology invented to realize bitcoin as a digital currency. Blockchain can be applied to a wider range. In addition to digital currency, it can also be applied to P2P loan, global payment, micro finance, electronic payment, remittance and other financial aspects. It can also be applied to intellectual property, election, notarization and other aspects of people's livelihood.
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
blockchain network visualization
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<
