Speaking of blockchain technology, we can first understand its three key characteristics. The first of them is its uniqueness. The arrival of the blockchain era can truly make virtual items unique; the second is its non-tamperability. In the blockchain, once the information reaches a consensus, the information is It cannot be tampered with, or it will leave traces after modification; the third is the credit layer. Blockchain technology uses distributed computing to form trust. Overall, the prospects of blockchain technology are still very good. Many investors still don’t know what the characteristics of this blockchain technology are? Let the editor of the currency circle introduce the characteristics of blockchain technology to you.

## What are the characteristics of blockchain technology?

Decentralization: Since the blockchain relies on various nodes to jointly maintain the system and ensure the authenticity of information transmission, it is based on distributed storage of data without centralized management by a center, so a node will not be attacked or tampered with. Affects the healthy operation of the entire network; the blockchain is not absolutely decentralized. Different architectures have different degrees of decentralization: depending on the application scenario, there can be complete decentralization, multi-center, and weak center. As the public chain is often said, it is a decentralized distributed ledger open to all Internet users, such as Bitcoin and Ethereum, which are completely decentralized public chain architectures.

2. De-trust: The establishment of a connection between any two nodes does not require trust in each other's identities, and the exchange of data between the two parties does not require the basis of mutual trust. Since all nodes in the network can act as "supervisors", there is no need to worry about fraud; due to the distributed sharing of ledgers, distributed storage of data, and distributed records of transactions, everyone can participate in this kind of In the distributed accounting system, the transaction information on the ledger is also open to everyone, so anyone can check, audit and trace the data information on the blockchain through the public interface. It is precisely because of the high transparency of the blockchain's distributed shared ledger that all related parties can be sure that the information in the on-chain database has not been tampered with and cannot be tampered with.

3. Scalable: Blockchain is an underlying open source technology, on which various extensions, decentralization, and trustless applications can be realized.

4. Anonymization: Both parties to the data exchange can be anonymous, and nodes in the network can exchange data without knowing each other's identities and personal information.

## The Prospects of Blockchain Technology

Blockchain is regarded as one of the most disruptive representative technologies in the 21st century.

Especially in recent years, the blockchain industry has been booming, and universities and some research institutions at home and abroad are paying more and more attention to blockchain technology. Currently, at least dozens of universities offer blockchain-related courses, including theoretical and practical parts.

With the promotion of 5G applications, the Internet of Things, artificial intelligence, virtual reality, augmented reality, autonomous driving and other technologies have achieved rapid integration and development, and we are about to usher in an intelligently connected world. At the same time, blockchain has fully penetrated into various financial scenarios and become a hot topic in the field of financial technology.

On May 28, 2018, General Secretary Xi Jinping delivered an important speech at the Academician Conference of the two academies, mentioning that “the new generation of information technology represented by artificial intelligence, quantum information, mobile communications, Internet of Things, and blockchain is accelerating breakthrough applications. "This is also the first time that blockchain has appeared in the speech of the country's top leader, affirming that blockchain technology is one of the representative directions of the new generation of information technology, and pointing out the direction for the development of blockchain in China.

In October 2019, General Secretary Xi Jinping emphasized at the 18th collective study session of the Political Bureau of the Central Committee: “Blockchain technology must be used as an important breakthrough for independent innovation of core technologies, clarify the main direction of attack, increase investment, and strive to overcome a Approval of key core technologies and accelerate the innovation and development of blockchain technology and industry.”

Through the above introduction to the characteristics of blockchain technology, I hope everyone can learn more about it. The current application of blockchain technology is divided into the following three aspects, namely blockchain digital currency, blockchain payment and clearing, and blockchain bank credit reporting. In fact, the development of blockchain technology is still in its infancy, and these technologies still have some technical flaws that are difficult to overcome. These flaws will also hinder the application of blockchain technology in various fields. However, as blockchain technology continues to develop in the future, it will be more widely used. By then, blockchain technology will have a huge impact on all aspects of our lives.
