⑴ 2. What is the difference between blockchain trust and traditional model trust?

The difference between blockchain trust and traditional model trust is as follows.
1. The most different thing about trust in the blockchain is that it uses mathematics, computer technology and encryption to make the record of information unchangeable, and writes the cooperation agreement on the blockchain through smart contracts, and finally in the conditions The contract is automatically executed after satisfaction. Blockchain eliminates trusted third parties. Through blockchain, people do not need to 100% trust each other or trust third-party institutions. It does not eliminate trust issues, nor does it completely eliminate the need to consider trust issues during the cooperation process. , people still need to trust, but the object of trust is changed from people and organizations to the blockchain network composed of consensus mechanism.
2. The traditional trust system mainly comes from two aspects: country and culture. The state uses its own credibility and public power to endorse the trust of both parties; culture refers to some implicit rules, such as the trust system of various regional customs and the possible emergence of private third-party institutions. The cost of state execution is too high, and it is impossible to rely on the state for everything. The cultivation of cultural trust takes too long and cannot meet everyone's needs. Society is very complex. It is impossible to sign a contract for everything, and it is impossible for the state to intervene in everything.

⑵ What are the characteristics of blockchain technology?

The four major characteristics of blockchain technology include: decentralization; trustlessness; scalability; anonymity. Decentralization: Due to the use of distributed computing and storage, there is no centralized hardware or management organization in the blockchain system. Therefore, the rights and obligations of any node are equal, and the data blocks in the system are maintained by the entire system. nodes to jointly maintain. Openness: The system is open. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface. Therefore, the entire System information is highly transparent. Autonomy: The blockchain adopts consensus-based specifications and protocols (such as a set of open and transparent algorithms) to enable all nodes in the entire system to exchange data freely and securely in a trustless environment, so that trust in "people" is exchanged. It has become a trust in the machine, and no human intervention will work. Information cannot be tampered with: Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, modifications to the database on a single node will be invalid, so the area The data stability and reliability of blockchain are extremely high. Anonymity: Since the exchanges between nodes follow a fixed algorithm, the data interaction does not require trust (the program rules in the blockchain will judge whether the activity is valid by itself), so the counterparty does not need to reveal its identity to the other party. Generating trust is very helpful for the accumulation of credit. Reliability: The data on the blockchain saves multiple copies, and the failure of any node will not affect the reliability of the data. The consensus mechanism makes it cost-effective to modify a large number of blocksExtremely high, almost impossible. Destroying data is not in the self-interest of important participants. This practical design enhances the reliability of data on the blockchain and global circulation: blockchain assets are first based on the Internet. As long as there is the Internet, blockchain assets can be circulated. The Internet here can be the World Wide Web or various local area networks, so blockchain assets are circulated globally. As long as there is the Internet, blockchain assets can be transferred. Compared with centralized methods, the transfer fees for global circulation of blockchain assets are very low. For example, the early transfer fee for Bitcoin was 0.0001 BTC. Compared with traditional transfers, Generally speaking, blockchain assets arrive very quickly. It usually takes a few minutes to an hour to arrive.

⑶ The difference between blockchain trust and existing trust

The differences are as follows:
1. The essence of blockchain is a distributed storage balance account book. It has the characteristics of decentralization, non-tampering and traceability.
2. These features have great application value for using closed date technology to build a new trust model in the future.

⑷ Is blockchain trust an endogenous trust?

Blockchain trust is an endogenous trust. The emergence of blockchain technology makes it possible to build mutual trust among large-scale actors. Based on the endogenous characteristics of blockchain trust, trust variables can be introduced into the existing economic system to solve market failures. Problems provide credible means.

⑸ Why is the blockchain a machine for creating trust?

In the blockchain system, bookkeepers are selected according to a set of competition rules, and everyone participating in the competition has Chance to win and be elected bookkeeper. Let's assume that this rule is a Rubik's Cube competition. Whoever solves the Rubik's Cube first will get the accounting rights. This reflects a feature of blockchain accounting: decentralized accounting. The account keeper is randomly generated by playing the Rubik's Cube game to ensure that the account keeper is no longer a centralized organization.

⑹ What is blockchain technology, what are its benefits, and what is building digital trust

The recent surge in value of digital currencies since their first appearance in 2009 has triggered a surge in the security field discussion on the benefits of blockchain. Blockchain is a technology that can facilitate the type of trust that is sorely lacking in certain digital transactions.

Today, people are exchanging cryptocurrencies at an increasing rate. But what makes cryptocurrencies so trustworthy? The answer is simple: everyone has their own blockchain.

What is blockchain technology, what are its benefits, and what is building digital trust?

Shifting the Burden of Trust

When we deposit money somewhere, we trust that it will not modify our account. Likewise, when we make a retail transaction, we expect to get enough goods in exchange for the money we spend. By adopting blockchain, cryptocurrency providers have removed the burden of trust from third-party financial institutions

Blockchain is a peer-to-peer network database that divides each transaction into its own block. In addition to cryptocurrency transactions, these blocks can also contain other sensitive assets such as identity information, patents, land titles, medical data, and more.

What is blockchain technology, what are its benefits, and what is building digital trust?

Once transactions are grouped into a block, a hash is assigned to the block so users can easily detect changes to the data. A block may contain a hash of the previous block, creating a block of blocks. This allows security professionals to trace the blockchain back to the first block or the genesis block when an attacker attempts to modify a transaction. Any changes will alter the hash of the block, requiring a potential threat actor to modify all blocks in the chain to complete the attack. For this reason, most cybercriminals believe that attacking blockchains and targets is unrealistic.

More benefits of blockchain

The blockchain is distributed among all participating nodes in the network, so anyone who joins the network can access the entire blockchain . Participants can collectively assess the effectiveness of the entire chain, meaning a potential attacker would need to control more than half of the participants to alter the final blockchain.

The mechanism of this consensus varies depending on the blockchain implementation. For example, one of the most hyped coins uses proof of work, which is a mathematical challenge that participants must solve in order to add a block to the chain. Other methods include proof of stake, proof of activity, and selective endorsement, each with its own advantages and limitations.

By examining the blockchain’s audit trail, participants can see a complete record of who owns a given asset, coin or token throughout its lifecycle. In other words, they can trace an asset’s origins and past transactions. Public key encryption further ensures non-repudiation and confidentiality.

No Limitations

Today, blockchain is often used as a currency ledger to facilitate smart contracts and identity management. In addition, there are projects building database networks that use distributed technology to serve supply chains, real estate, voting systems, and more.

After all, a technology actually guarantees trust between participants and provides visibility into sensitive transactions. As encryption becomes more popular and the need for verification increases, blockchain technology will also get greater improvements

⑺ How important is blockchain

< p> With its exquisite design concepts and thinking, blockchain can promote the reconstruction of the rule system in economic and social fields, change the collaborative relationship and benefit distribution mechanism between people, people and organizations, organizations and organizations; at the same time, blockchain Chain technology can effectively solve the "double spend problem", which prevents the same digital asset from being reused due to improper operations.

This provides a solution to the problem of digital asset rights confirmation and transaction circulation. It can break through the problems of digital asset rights confirmation and double spending that restrict digital development, and build a new production relationship that adapts to the development of the digital economy. This Become the most important value of blockchain technology.

01 Reduce transaction intermediate links and promote cost reduction and efficiency improvement

There are a large number of rent-seeking intermediary organizations in various fields of economic and social life. Some of these organizations do not create real value, but only seek profits through the monopoly of business information or data. , artificially increasing unnecessary transaction links and costs.

Through the innovative application of blockchain, a self-organizing mechanism for economic behavior based on technology can be built to replace the business role of some intermediaries, which can greatly improve data acquisition. , consensus formation, accounting and reconciliation, and value transfer efficiency, further open up the upstream and downstream industrial chains, significantly reduce unnecessary intermediary organizations and intermediate links, improve the efficiency of effective docking of supply and demand in various industries, reduce the burden on the public and commercial entities, and promote The real economy reduces costs and increases efficiency.

02 Help confirm the rights of digital assets and stimulate innovation vitality

In the era of digital economy , data resources are becoming more and more important. In 2019, my country has officially regarded data as one of the seven production factors as important as labor, capital, land, knowledge, technology, and management, and has promoted the establishment of a data factor market system.

However, due to the difficulty in confirming data rights, tracing back, and dividing interests, data cannot yet achieve efficient market-oriented allocation and orderly circulation, seriously restricting the development of the digital economy. develop.

Distributed, non-tamperable, traceable, With features such as transparency, multi-party maintenance, and cross-validation, data ownership can be effectively defined, data circulation can be tracked and supervised, and data revenue can be reasonably shared, removing obstacles to the efficient market-oriented allocation of data production factors and other digital assets. It is expected that Reversing the current trend of increasing centralization of data ownership, use, and benefit distribution, promote the entire society and digital economy to develop in a more trustworthy, shared, and balanced direction, and further release the innovation vitality of the digital economy.

03 Shortening the distance of trust and expanding the space for collaboration

Modern human lifestyle ofChange and progress are all directly related to the development of science and technology. Scientific and technological revolutions always dialectically expand the territory of human activities while shortening the distance between them. Every major technological change is always accompanied by the collapse of "distance" in some sense, thus bringing convenience to people.

For example, the invention of transportation has expanded the radius of human activities and shortened the geographical distance between people; the invention of communication tools has expanded the radius of human "conversation" The physical distance has been shortened; the invention of the Internet has expanded the radius of human access to information and shortened the distance of information; the invention of artificial intelligence has expanded the radius of cognition and shortened the distance of cognition of the world.

Blockchain shortens the distance of trust

Today, blockchain has brought us a new radius expansion. Blockchain can form a trust mechanism based on cryptographic algorithms without relying on authoritative centers and market environments, allowing strangers who are thousands of miles apart, have never met or even never met to establish a trust relationship, expanding the radius of human trust, thus making strangers Cooperation becomes possible.

Especially in some regions and fields with imperfect market mechanisms and lack of credit systems, the value of blockchain technology is even more precious. Blockchain technology enables strangers to establish production relationships based on technical constraints, making it possible to carry out business cooperation in unfamiliar environments, and is expected to inspire a series of new business models.

04 Driving the Internet Revolution and Accelerating Value Delivery

The first 20 years of the 21st century , human society has experienced the comprehensive baptism and reconstruction of the Internet. "Internet +" has brought about earth-shaking changes in related industries and fields. People's lives have become more convenient because of the Internet, economic activities have become more active because of the Internet, and society has become more fair and open because of the Internet. .

However, the Internet mainly solves the problem of dissemination of information. It is difficult to judge the authenticity of information content, and there are still many constraints and obstacles to the transfer of digital assets. While the Internet brings great convenience, it is also filled with more and more false information, and has even become a hotbed for various new types of fraud. While people are becoming more and more dependent on the Internet, they are also increasingly wary of the Internet.

Based on blockchain technology, the next generation of reliable technology based on technical constraints can be built. Trusting the Internet and solving the trust problem of strangers on the traditional Internet will allow digital assets to circulate efficiently on the Internet. Based on blockchainTechnology can effectively protect digital assets and intellectual property rights on the Internet. Asset transactions between people will be as convenient as sending emails. People will put down their guard against the highly dependent Internet because of the innovation of blockchain technology. The Internet will Create more valuable applications.

05 Strengthen the constraints of the integrity system and purify the market environment

Blockchain is a Trust the machine. By promoting the deep integration of blockchain and the real economy, a market environment that is convenient, efficient, fair, competitive, stable and transparent can be created. The technical characteristics of blockchain technology that cannot be tampered with and are traceable can play a very important role in the innovation of trust mechanisms in regions and fields with imperfect market mechanisms and incomplete credit systems.

Under the traditional model, market supervision requires a heavy workload and is difficult to implement. Due to insufficient administrative law enforcement resources and regulatory means, it is widely hated by the public. The phenomena of laobao, counterfeit products and fraudulent behaviors are repeated and difficult to eradicate.

Blockchain technology can be formed without the need for intermediaries and laws and regulations. The conditional self-organization and self-supervision mechanism, and the non-tampering, non-repudiation, and non-manipulability of the distributed ledger actually play a role in technical supervision of various economic behaviors.

This will help solve problems such as difficulty in loan financing for small and medium-sized enterprises and difficulties in bank risk control; by recording the entire product production and transaction circulation process, it can significantly reduce the risk of counterfeiting, Various market frauds such as passing off substandard products to solve problems such as difficulty in market supervision.

⑻ Behind the rise of “digital collections”: how to ensure the credibility and security of digital assets

With the metaverse, NFT (non-fungible) With the popularity of concepts such as tokens, a large number of NFT trading platforms have emerged in China, and "digital collections", a Chinese product of NFT, have entered the public eye.

Public data shows that there are currently more than 70 domestic digital collection platforms, including many major Internet companies such as Ant Group, Tencent, and JD.com.

The so-called digital collection refers to the use of blockchain technology to generate unique digital certificates corresponding to specific works and artworks. On the basis of protecting their digital copyrights, they can achieve authentic and credible digital distribution, Buy, collect and use.

“The characteristics of blockchain that cannot be tampered with and have lifetime traceability make itIt plays an irreplaceable role in the copyright protection and confirmation of digital content, and it can also play an increasingly important role in the value circulation of data assets. "On March 30, Yin Keting, dean of Ningbo Standard Blockchain Industry Development Research Institute and executive deputy director of the Blockchain Research Center of Zhejiang University School of Software, pointed out in his speech at the first China Credit Union Digital Collection Summit Forum that blockchain can Allow high-value data such as "digital" artworks to be transmitted and shared unimpeded.

It should be noted that while digital collections are developing rapidly in our country, they lack certain legal protection and supervision mechanisms. Fudan Ling Hong, director of the University's Smart City Research Center, reminded that practitioners need to fully realize the importance of digital collection market supervision, digital property rights certification, and industry compliance development, and work together to create an authoritative and credible system for digital collections that is suitable for my country's actual conditions. The value circulation platform promotes the long-term and healthy development of digital collections in our country, allowing collectors and enthusiasts to enjoy the value brought by digital collections. At the same time, digital collection platforms need to play an extremely important role - in addition to artworks, traditional commodities Digitization gives digital collections a broader space.

According to Tang Quan, consulting director of Chain City Digital Technology Co., Ltd., ensuring the credibility and security of digital assets is the core issue in the development of the digital collection industry. The most important thing is to build an infrastructure where the members on the chain are clear, the data on the chain is indestructible, and the behaviors on the chain can be trusted and endorsed, so that the value of the digital assets on the chain can be truly ensured.

In this regard, Yin Keting Agreed. He emphasized that the development of the digital collection industry requires more credible, secure and efficient infrastructure as support.

On the same day, the country's first and largest public trust alliance chain "Certificate Chain" announced Officially supports the enterprise-level digital collection platform. Under the authoritative endorsement of the China Credentials Alliance, it opens up the capabilities of the trusted infrastructure of the Credentials Chain to provide technical operation services for institutions that need to build digital collection platforms.

According to Tang Quan, the Credit Certificate Chain links more than 30 provincial and municipal public trust institutions across the country to create an infrastructure and trusted data usage interface for a trusted digital society, and can play an important role in the metaverse and digital collection fields.

It is understood that the China Credit Credentials Alliance was initiated by the Ningbo Standard Blockchain Industry Development Research Institute and is composed of notary offices in various provinces and cities across the country, Zhejiang Municipal Supervision and Judicial Appraisal Center, Zhejiang Intellectual Property Protection Center and other enterprises and institutions. Technical support is provided by Chain City Digital Technology Co., Ltd. The alliance achieves national collaboration and service innovation through "building a chain into a network", providing a trusted environment and trust endorsement for every electronic data and digital asset, and building a trustworthy, safe and efficient The value of Internet trust infrastructure.

The relevant person in charge of the China Credit Credentials Alliance said that in the future, it will focus on digital assets, intellectual property protection, market supervision, notarization innovation and other fields.Continuously build more innovative application scenarios for trusted data, give full play to the value of credible institutions, link the "first mile" and "last mile" of the trusted digital world, and create a healthy and orderly industrial ecosystem for the value Internet.
