❷ What is blockchain technology and how it changes business and financial models

Blockchain technology is a distributed ledger technology that allows Multiple participants work together on a decentralized network to maintain a secure, transparent and immutable record. Blockchain technology was originally designed for the digital currency Bitcoin, but is now widely used in many other fields.

The core features of blockchain technology include:

Decentralization: Blockchain has no central control agency, and data is distributed on various nodes in the network, which makes it decentralized. The centralization feature reduces the risk of single points of failure.

Transparency: Transaction records on the blockchain are public to all participants, and anyone can view these records. This helps increase trust and reduce the risk of fraud.

Immutable: Once a transaction is recorded on the blockchain, it cannot be easily modified or deleted. This guarantees data integrity and security.

Smart contracts: Transactions on the blockchain can be automatically executed to implement "smart contracts", which automatically execute corresponding operations when specific conditions are met. This helps simplify complex business processes and reduce costs.

Blockchain technology has had a profound impact on business and financial models.The far-reaching impact is mainly reflected in the following aspects:

Reducing costs: Blockchain technology can reduce intermediary links and reduce transaction costs and operating costs. For example, by adopting blockchain for cross-border payments, remittance fees can be significantly reduced.

Improve efficiency: The automation and smart contract features of blockchain technology help improve the efficiency of business processes, reduce manual intervention, and reduce error rates.

Enhance trust: The transparency and non-tamperability of blockchain technology help to establish a reliable trust system, reduce the risk of fraud, and provide better protection for business activities.

Innovative business models: Blockchain technology has spawned many new business models, such as decentralized finance (DeFi), digital asset trading, supply chain finance, etc. These new business models have brought disruptive changes to existing industries.

In short, blockchain technology, as an emerging technical means, is gradually changing the landscape of business and finance. With the continuous development of technology and the in-depth promotion of applications, blockchain is expected to have a more extensive and far-reaching impact in the future

❸ Essential characteristics of blockchain smart contracts

Blockchain The essential characteristics of smart contracts: decentralization.

Some of the main advantages of using smart contracts include greater efficiency when processing documents. This is thanks to its ability to employ a fully automated process that does not require any human involvement, as long as the requirements listed in the smart contract code are met.

The result is that time is saved, costs are reduced, transactions are more accurate and cannot be changed. Additionally, smart contracts remove any third-party interference, further enhancing the decentralization of the network.

(3) Extended reading of blockchain attributes decentralized smart contracts :

Smart contracts can only use digital assets, and problems will arise when connecting real assets and the digital world. Finally and most importantly, smart contracts lack legal supervision and are only subject to the obligations agreed in the code. The lack of legal regulation may lead some users to be wary of transacting online, especially if it is significant.

The advantages of using smart contracts are more efficient processing of transactions, irreversible, secure transactions and fully automated processes. On the other hand, the disadvantages are the lack of legal supervision, human errors and difficulties in implementation.

❹ What is the role of smart contracts in blockchain technology

Smart contracts are one of the four core technologies in blockchain. This concept was first developed in 1994. It was proposed by the well-known cryptologist Nick Szabo, but due to technical and other reasons it has never been implemented. Even today, smart contracts have been used in many applications on the Internet, such as automatic repayment, drone sales, etc. , most of them are limited to smart contracts between individuals and institutions. There are almost no smart contracts between individuals. The reason is the "trust" issue. WeWe will find that whenever we talk about contracts, most of them are strangers who have this kind of demand, and it is also related to money. If we make an agreement without a third party as a guarantee, I sent you money, but you broke the contract. What should I do if you don't admit it? Therefore, smart contracts have never been popular among individuals. Later, with the emergence of blockchain, people found that blockchain is very consistent with smart contracts, because of many characteristics of blockchain, such as Decentralization, non-tamperability of data, etc. can solve the problem of trust between strangers from a technical perspective. This makes the large-scale application of smart contracts possible. The beginning of this stage is marked by the birth of Ethereum. . Based on the blockchain, Ethereum applies smart contract technology. Smart contracts enable Ethereum to achieve more functions. Smart contracts are a very important application, so slowly, smart contracts have become one of the core technologies of the blockchain.

❺ What is the blockchain technology architecture?

The architecture of blockchain technology includes the following aspects:

Decentralized network: blockchain The core of technology is decentralization. Its network structure is different from the traditional centralized network structure. It realizes data transmission and verification through point-to-point method, thereby achieving the purpose of decentralization.

Consensus mechanism: The consensus mechanism is an important means to ensure data security and reliability in the blockchain network. The consensus mechanism can ensure data consistency among all nodes in the blockchain network. Common consensus mechanisms include proof of work, proof of equity, and share authorization.

Smart contract: Smart contract is another important component of blockchain technology. It is a computer program that can automatically execute and verify contracts and can be programmable on the blockchain network. Automated trading. Distributed storage: Distributed storage is another important component of blockchain technology. It realizes distributed storage and backup of data by storing data on various nodes of the network, thereby improving the security and reliability of data. .

Common numerical features include expectation, variance, standard deviation, etc. These indicators can be used to describe the central trend, degree of dispersion and other characteristics of random variables, and can also be used for probability calculations and risks. Analysis etc.

❻ What is blockchain

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is an important concept of Bitcoin.

It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains a batch of The information of Bitcoin network transactions is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

Characteristics of blockchain:

1. Deposit certificate

The "non-tamperable" feature of blockchain provides economic benefits It provides a solution to the problem of “evidence preservation” in social development. As long as the authenticity of the on-chain information and data can be ensured, the blockchain can solve the problem of "storage" and "certification" of information.

For example, in the field of copyright, blockchain can be used to store electronic evidence, which can ensure that it is not tampered with, and can link original platforms, copyright bureaus, judicial agencies and other parties through distributed ledgers, which can greatly Improve the efficiency of handling infringements.

2. Sharing

The "distributed" characteristics of the blockchain can break through the "data barriers" between departments and achieve information and data sharing. Different from centralized data storage, the information on the blockchain will be distributed to each node through point-to-point broadcasting, and all information can be "truthfully recorded" through "whole network witness".
