​Attention
Today, let’s talk about the common misunderstandings about blockchain application scenarios. , in order to prevent the misunderstanding from deepening, Xuanling Technology needs to explain. What is blockchain? Is blockchain equal to Bitcoin? Is the blockchain public? Is the ledger immutable? Is the financial industry not suitable for blockchain? With the above questions, we will answer them one by one.

What is Blockchain?

Blockchain technology is a decentralized ledger that allows a shared set of computing systems to agree that transactions between multiple parties are authentic . These results will be permanently recorded in a cryptographically secure manner and continuously coordinated and updated. Because the ledger is distributed among all transaction participants, it exists in multiple locations simultaneously, making it extremely difficult to manipulate entries or tamper with data without other parties noticing. Therefore, what makes blockchain so important is its ability to automate trust and transparency among the parties using it.

Perhaps one of the most important innovations in the blockchain space is the reinvention of smart contracts. Smart contracts have been around for decades but are now being reimagined to operate and automate business processes in a completely decentralized manner, enabling shared rules of engagement, behaviors, and business processes to be automated and enforced across the entire ecosystem. Smart contracts extend blockchain applications beyond cryptocurrencies.

Myth 1: Blockchain is equal to Bitcoin.

B. The statement about the future development of blockchain is incorrect

The statement about the future development of blockchain is incorrect because the problem of blockchain shows that it goes against the inevitable trend of development. The problems of blockchain show that its development path is tortuous, it is a new trend, and it does not go against the inevitable trend of development. Blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it has the characteristics of being unforgeable, leaving traces throughout the process, traceable, open and transparent, and collectively maintained.

C. Which of the technologies used by blockchain does not include?

The technologies used by blockchain do not include big data

1. P2P network technology

In fact, before the emergence of blockchain, distributed P2P peer-to-peer network was already a very mature technology.

2. Encryption technology

In terms of encryption technology, blockchain uses an asymmetric encryption algorithm.

3. Smart Contract

The term "smart contract" was first proposed by legal scholar Nick Szabo in 1995.

4. Consensus mechanism

In the past, we have paid an extremely high price for trust, and blockchain will incredibly change that.

Blockchain is revolutionizing various ways to pay for e-commerce:

1. Faster payment processing

2. Easily process receipts and warranty vouchers< /p>

3. Self-executing smart contracts

4. Reduce handling fees

5. Prevent network attacks

D. About the block below What is wrong with the statement of chain storage certificate

Blockchain is a temporary and irreversible generation of encrypted data superimposed in chronological order. What is wrong with the following statement about blockchain evidence is that blockchain is a temporary, irreversible generation of encrypted data superimposed in chronological order. Blockchain is a chain composed of blocks one after another. Each block stores certain information, and they are connected into a chain in the order of the time they were generated.

E. Seven major misunderstandings about blockchain

Seven major misunderstandings about blockchain
Blockchain-based systems have broad prospects for the future, but we One needs to be very clear about what blockchain can do. Imagine blockchain technology in the next 20 years, its impact may be as big as the Internet.
But what is shocking is that today we mainly see projects that seem to be based on decentralized design, but in fact there are some misconceptions about blockchain.
If we want technology to continue to advance in the right direction, we need to translate this enthusiasm into productive and realistic expectations, thereby reducing the likelihood that the supply chain will hit "rock bottom" once it does. ”, it may be discarded in the corner along with the meaningless proof of concept, and no one cares about it.
Let’s look at the top seven myths that place unrealistic expectations on blockchain:
Myth 1: Highly scalable
Compared to traditional (server-based) transactions Compared to other methods, blockchain deployments are not truly scalable, and transaction times currently depend on the slow side. They are only scalable for certain types of transactions, such as those with small payloads and close to certain limits. You can't just pile information on the blockchain.
Myth 2: It is absolutely secure
Although blockchain is based on encryption standards, the method of ensuring privacy is completely outside of any blockchain standards and implementations. Only crypto experts can truly understand and verify blockchain integration. However, each implementer is responsible for ensuring security, so the way this is handled is largely the same as how financial transactions were managed in the old days.
Myth 3: Trustworthy
Blockchain ensures the integrity of transactions and information, otherwise anything stored in the blockchain cannot be trusted. You need to be sure that it is truly trustworthy by ensuring that the parties storing facts in the blockchain are trustworthy and can ensure the authenticity of the facts. This governance model allows multiple parties to take joint responsibility for the infrastructure while requiring secure access to store facts in the blockchain.
Myth 4: You can put anything in the blockchain
Blockchain is a protocol expressed in code, and it is not defined according to any standard. There is no standards body to provide rules or guidance for the implementation of sanctions.
Typically, you can only handle small payloads, and you still need agreed upon standards between all participants for anyone to understand what is stored.
Myth 5: Anything can be expressed in a smart contract
While this is technically possible, in practice, blockchain is limited to simple and easy-to-understand use cases. Smart contracts are very complex in nature. By design, once published, you cannot modify or fix them. They contain very complex interactions and irrevocable consequences.
Myth 6: If you don’t like public chains, please choose private chains
Private chains are not a channel for obtaining privacy or accessing restricted information. In fact, you could even argue that private blockchains shouldn’t be a public option. Nonetheless, enterprise blockchains may not realize any of the inherent advantages of blockchain technology, and privately developed blockchains may lack the community and academic scrutiny necessary to ensure their properties.
Myth 7: The size of the community does not matter
Blockchain products driven by the community are being forked in various aspects by private players who are strengthening their role in various ways. However, a large community of adopters, users, academics, and implementers is the only force that ensures cryptographic properties are effective. Only the open source blockchains with the largest community and installed adoption base will last. The rest can be considered laboratory experiments, 99.9% of which will "die".
Technically savvy people move forward based on use cases and a set of first principles in mind. First, there may never be one blockchain to govern them all. Two different use cases require different blockchains. Some will have many participants, some will have few, some will require strong privacy around the facts, and some will have full transparency.
With all of the above in mind, what we can do together now is innovate, attack real business problems, and launch proof-of-concept drives to better understand the power of blockchain.

F. Which of the technologies used by blockchain does not include?

The technologies used by blockchain do not include big data

Blockchain technology Including distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other technical applications. It was developed based on needs after market research by experts, sports experts and the operation team.

2 Public blockchain The public blockchain is the earliest blockchain and the most widely used blockchain at present.

3 The alliance chain designates multiple pre-selected nodes within a certain group as bookkeepers, and the generation of each block is jointly decided by all pre-selected nodes. Other access nodes can participate in transactions,But regardless of the accounting process (essentially still managed accounting, it just becomes distributed accounting, how many pre-selected nodes, and how to decide the accountant of each block become the main risk points of the blockchain), anyone else Restricted queries can be made through the blockchain’s open API.
