❷ Blockchain development action plans "Blockchain+" have been issued in many places to show off their potential

< p> [Zhongya Finance] Recently, Hebei, Guizhou, Hunan, Beijing, Guangzhou, Ganzhou and other provinces and cities have released blockchain development action plans to plan for the construction of blockchain platforms and promote the "on-chain" of enterprises. Domestic The blockchain industry is ushering in rare development opportunities. At present, blockchain technology has been implemented in judicial certificate storage, government affairs management, people's livelihood services, food traceability, supply chain management and other scenarios. In the future, it may show its talents in new infrastructure, industrial chain transformation, public services and other fields, providing high-quality services. Quality development is gaining momentum.

During the epidemic prevention period, Mr. Ma, a Beijing citizen, fell in love with online shopping. After he recently received a box of Anhui Dangshan Su pears, he found a QR code with "Blockchain Traceability" written on the package. Scanning it with his mobile phone revealed the name of the e-commerce company selling the pears, the location of the authentic place of origin, and the product. Features, quality alliances and other "identity" informationAt a glance, even the number of scanned codes is clearly displayed. Mr. Ma said: "Seeing such detailed and accurate product information makes me more confident in the quality of the product."

The application of blockchain technology in online shopping has been an active innovation technology application scenario in recent years. an epitome of. According to the "2018-2019 China Blockchain Development Annual Report" released by the China Blockchain Ecological Alliance, blockchain technology is most actively used in the financial field, and has formed an important role in cross-border payments, asset management, supply chain finance, etc. A batch of new products that can undertake actual business; phased results have been achieved in the fields of electronic certificate deposits and charity; and exploration has begun in the fields of medical services, government management, transportation and logistics.

Against this background, many domestic provinces and cities have recently issued blockchain development action plans. In the plan, building a blockchain open innovation platform and promoting the "online" of key enterprises have become the next focus of local work. For example, the "Beijing Blockchain Innovation Development Action Plan" issued by Beijing in early July proposes to take the lead in forming a "Beijing Plan" for blockchain to empower economic and social development by 2022; Guizhou Province issued in early May "About Accelerating District Development" "Opinions on Blockchain Technology Application and Industrial Development" proposed that by 2022, 3 to 5 blockchain open innovation platforms and public service platforms will be built, and more than 100 growing blockchain companies will be introduced and cultivated; Hunan Province will The issued "Three-Year Action Plan for the Development of the Blockchain Industry in Hunan Province (2020-2022)" proposes to build more than 10 blockchain public service platforms by 2022 and promote 30,000 companies to get on the chain; Guangzhou, Guangdong, Ganzhou, Jiangxi It is also proposed to cultivate a number of key blockchain enterprises and promote typical application demonstration scenarios.

During the epidemic, various places "increased" the development of blockchain technology. Experts said that since this year, the demand for digital social governance innovation and soft and hard infrastructure construction has increased significantly, and the potential of blockchain technology in the technical transformation of industrial chains and government governance has become more prominent.

“As more and more people realize and enjoy the convenience brought by digital life, they are more determined to carry out digital reform. , the determination to actively 'get on the chain'." Pan Helin, executive director of the Institute of Digital Economy of Zhongnan University of Economics and Law, said that during the epidemic prevention period, blockchain technology has advantages in information management, emergency supplies and food safety traceability, and identity authentication management. obvious. For the digital economy or blockchain technology, this epidemic is a development opportunity. After the epidemic has spawned a large number of digital demands, blockchain will play a more important role in production and supply chain collaboration, public safety warning, and financing of small and medium-sized enterprises. Big energy.

Use blockchain technology to create a "virtual factory" for Nankang furniture to trace the origin of Gannan navel orange products... In recent years, Ganzhou blockchain companies have continued to emerge, involving digital certificates, digital bills, anti-counterfeiting traceability, filing and notarization, copyright protection, digital finance and other services are also increasing. To this end, the local government has recently established a blockchain service hall to ensure that these businesses are handled centrally.

Some experts said that from a nationwide perspective, this kind of blockchain service model innovation will crack the blockchain technology and Attempts to combine people's livelihood and the real economy are gradually increasing. As an emerging technology in the digital economy era, blockchain technology also faces many difficulties and obstacles in scientific research and implementation. In terms of technology, blockchain encryption technology faces technical risks such as inference and even traceability; in terms of implementation, there are limited application fields. , low industrial agglomeration effect and other problems; in addition, there are bottlenecks such as lack of professional talents.

Action plans released in many places also target these difficulties and congestion points. For example, the "Beijing Blockchain Innovation and Development Action Plan" proposes four key tasks: innovation-led, building a blockchain theory and technology platform; demand-driven, building a number of multi-field application scenarios; cluster development, cultivating integration linkage The blockchain industry; ensuring the elements and building a leading blockchain talent echelon.

Affected by the epidemic, the accounting period of downstream engineering projects in some industries has become longer, and the pressure on upstream small and medium-sized suppliers has increased accordingly. This once made some small business owners very anxious and afraid to take on big orders.

How to open up business flow, logistics and capital flow, so that the upstream and downstream of the industrial chain can "turn" together? Zhejiang’s approach is to build a blockchain receivables chain platform. The platform puts accounts receivable accumulated in the supply chain online as "blockchain receivables", solving the risk of fraud that is difficult to prevent in traditional accounts receivable financing. After upstream suppliers receive the blockchain receivables issued online by the supply chain enterprises, they can transfer them to the bank for cash on the same day, eliminating the need for cumbersome procedures such as verification and verification, witnessing and confirmation of rights, and "hardening" the upstream and downstream industry chains. “Funds have been mobilized.

Currently, blockchain applications are still in the early, niche and pilot stages. With the implementation of 5G technology, the increase in market data volume and the improvement of technical issues, more application cases are expected to appear in the future.

Experts said that in order to achieve safe and sustainable development of blockchain technology, we must first solve the technical problems, especially the realization of technical security, decentralization, scalability and other issues, which requires all parties to Cooperate fully; secondly, we must promptly pass legislation to protect the legal issues that may be faced during the development of blockchain technology, and at the same time severely crack down on the use of blockchain technology to commit illegal crimes.

❸ REC is hotly launched in the Coin One 8-hour trading area, and position rewards and airdrop activities are open

After review by the Coin One Review Committee, REC is in line with the Coin One (BCCE) digital asset trading platform. Standard, the 8-hour trading area of ​​Biyi Exchange will soon launch REC, and the REC/USDT trading market will be opened.

Real estate has a high proportion of asset allocation around the world and is the main storage method of national, corporate and personal wealth. Real estate in the global investment market, especially in the field of large-scale real estate transactions, is faced with a problem: how to make asset transactions easy, efficient, and transparent.

Based on traditional real estate investment tools, asset holders can quickly transfer real estate asset ownership and ownership through REC (Real Estate Chain) preliminary review, risk control, and asset package income estimation. Yield trading greatly improves liquidity. To achieve the purpose of securitization of physical real estate assets.

At the same time, in order to celebrate the successful launch of REC, Biyi Exchange and REC have opened net buying and airdrop activities to the majority of users. For every 1,000 RECs a user's net holdings exceed, they will be rewarded with 50 RECs, with no upper limit! New users also enjoy a registration gift. Users who register for the first time during the event will receive 20 REC rewards.

REC——Blockchain real estate investment model

The REC project has been positioned as a real estate blockchain transaction chain in Southeast Asia since its preparation. REC focuses on integrating the Southeast Asian real estate transaction market through blockchain mechanisms. By linking the blockchain mechanism to real estate, connecting real estate developers with financial institutions and their users, real estate transactions will be included in the layout of Southeast Asia's "digital credit society" and play an important supporting role in economic development. All real estate owners and investors can benefit from the REC real estate blockchain mechanism.

Combining the advantages of blockchain and the development trend of Southeast Asia, the blockchain-based real estate investment model is very likely to cover future real estate investment in Southeast Asia at a sweeping speed and eliminate the traditional real estate investment model. The REC project is based on this development turning point, draws on REC's method of securitizing real estate, uses smart contracts to fragment real estate property rights, and is the first to create a blockchain + smart contract + REC business model in a forward-looking manner, which will subversively Increase the liquidity of real estate in Southeast Asia, thereby affecting the economic development of Southeast Asia.

Judging from the current business development situation, both the real estate side and financial institutions have shown great enthusiasm. More and more real estate developers and financial institutions have expressed their willingness to actively participate in the REC project and look forward to the launch of REC's blockchain project REC (Intelligent Housing Chain) as soon as possible.

It is reported that in REC’s future development blueprint, in addition to Southeast Asian real estate, all assets with exchange value will also be included in the scope of REC (Smart House Chain) blockchain. For example, art, antiques, bonds, etc.

❹ Jingniu Chain, the first sub-chain of ETO public chain, is about to be launched, helping real enterprises enter the new era of "blockchain+"

Jingniu Chain, the first sub-chain of ETO public chain, is online Soon, we will help physical enterprises enter the new era of "blockchain +"

Blockchain has been around for more than ten years. In recent years, with the increasing maturity and application scenarios of blockchain technology, With the continuous enrichment of blockchain technology, more and more people are paying attention to blockchain. Especially on April 20 this year, the National Development and Reform Commission clearly proposed for the first time that blockchain be included in the scope of my country's "new infrastructure". Blockchain has become a key technology to enhance the efficiency of China's existing assets and improve medium- and long-term industrial competitiveness.

The importance of chain reform

Why is the blockchain brought to such an important position? In essence, blockchain realizes the openness, transparency and non-tamperability of data through the consistent distribution and redundant storage of data across the entire network, reduces information asymmetry at the system level, and enables nodes to implement business based on new information acquisition capabilities. Reorganization of relationships. While decentralizing information systems, blockchain also improves overall efficiency by decentralizing business systems and disintermediating business processes.

The essential requirement of real economy reform is to reduce costs and increase efficiency. The purpose of developing the digital economy is to serve the real economy. Blockchain plays an extremely important role in this process.

The so-called "chain reform" is, on the one hand, the reconstruction and reorganization of business processes in the real economy through blockchain, and the realization of data with decentralized business systems and deintermediated business processes. Distribution and storage on the chain; on the other hand, by introducing the token economy, the interest structure of different subjects in the business system is adjusted to enhance the overallThe value flow efficiency of the supply chain system and the benefit distribution model are reconstructed. This is why chain modification is so important.

From a technical perspective, chain reform can solve issues such as trust, security, privacy protection, cost reduction and efficiency improvement by putting applications on the chain, information on the chain, and assets on the chain. From the perspective of token economy, chain reform can change the way economic value is produced, transferred, and distributed, so that all contributors to the entire ecosystem can receive corresponding rewards for their efforts.

Chain reform transforms the identity of "consumer" into the identity of "consumer + communicator + investor", transforms the opposing parties of interests into a community of interests, and improves the stickiness of end consumers; through incentive model design , thereby liberating production relations, improving the collaborative value of the upstream and downstream supply chains, and maximizing benefits. In the long run, chain reform is of great significance to the development and progress of the entire society and the improvement and protection of personal income.

Jingniu Chain focuses on one-stop chain reform services

Jingniu Chain is the world’s leading one-stop chain reform service focusing on chain reform of the real economy and digital equity of real enterprises platform. On the one hand, Jingniu Chain is committed to helping small and medium-sized enterprises solve internal and external incentive problems through blockchain technology, obtain instant incentive feedback internally, and improve the collaborative efficiency of upstream and downstream industries externally; it provides personalized chains based on the product characteristics of different enterprises. Change the plan to allow enterprises to gain differentiated competitive advantages.

The specific destruction mechanism is: 5% of the quota is always released to the mining pool for destruction every day, and the explosion mechanism is used to reward participants. Miners need 3% of the equivalent ETO. (That is, the platform token of the ETO equity public chain) As a miner fee to participate in the explosion, the mining pool will receive random returns ranging from 2 times, 3 times, 4 times, and 5 times according to the destruction amount. The coins returned by the miners will be 2% of the balance will be released every day until the quota of the destruction mining pool is exhausted. The unexploited quota on that day will be deposited in the destruction mining pool.

In terms of mining fees, staking or withdrawing JNL requires the equivalent of 3% ETO as the token, and transactions and transfers require the equivalent of 0.3% ETO as the handling fee.

In addition, 3% of the daily mineral production will be converted into 1% charity fund, 1% tourism fund and 1% learning fund respectively.

As the world's leading chain reform and digital equity service platform, Jingniu Chain not only has a top international team lineup, covering chain reform and digital equity service implementation cases in multiple industries, but also can provide comprehensive and multi-faceted services. Channel promotion and operation, investment and mergers and acquisitions, digital equity transformation, listing and circulation transactions and other services, JNL plays an important role as the value-carrying circulation medium of the entire ecosystem.

In the future, as more and more small and medium-sized entities realize the importance of blockchain and the continuous development of chain reform platforms represented by Jingniu Chain, more "blockchain + "The industry will be implemented, and global entities will enter a new era of "blockchain+".

❺ What are the blockchain scenario application projects

Develop an ap based on the latest datap probably costs tens of thousands to several million.

There are many factors to consider when developing an Android app software. If it is an APP with simple but not comprehensive functions and few customer requirements, you only need to ask the artist to modify the front-end UI page to a certain extent, which can be completed in as little as one or two days, and the cost will be several thousand yuan.

To develop a complete Android app, a simple one requires tens of thousands, and a complex one requires tens or millions. Android is not more difficult than IOS, and many teams can contract it.

(5) Extended reading of the upcoming blockchain project:

Software maintenance

1. Delete the useless installation package apk in time after installing the App

p>

Mobile phones and personal computers are very similar, and they have many similarities in maintenance methods. Nowadays, many ROMs that have been improved by mobile phone manufacturers are very considerate. Generally, after installing an App, you will be reminded whether to delete the installation package. If there is no other use, you can delete it immediately. If the mobile phone does not have this function, you can also delete it manually. .

2. Clear the cache regularly

Long-term use of social applications will generate a lot of cache, and the application itself will not delete it. Over a long period of time, a lot of cache will be accumulated, occupying storage space and causing It is stuck, so you can use the clear cache function in the application management in the phone settings to delete it. You can also use a system maintenance app that has the function of cleaning up junk. You can also uninstall and reinstall it.

3. Close unused programs promptly when using them

Although the Android system will automatically end some processes when memory is tight, in actual applications, you should have the awareness to prepare for a rainy day. , usually just end the currently unused apps on the multi-tasking interface to release the current running memory of the phone, which not only helps the phone run efficiently, but also prevents the traffic from being wasted when its background software is running.

❻ CSPR is about to be listed on Huobi or will continue to rise. What kind of project is cspr?

CSPR is also called Casper. This project is dependent on the Ethereum ecosystem. Moreover, it can smoothly transfer projects on Ethereum based on its own compiler, and jointly build and continue the prosperity of the Ethereum ecosystem. It is worth mentioning that CSPR (Casper) has also established a DevDAO organization, which can provide technical and financial support to developers in its own ecosystem. This is also a point worthy of attention. After all, with technology and funds Only with support can we achieve long-term development. Another point is that CSPR has very good corporate relationships and can connect the traditional world with the blockchain world to further promote the common prosperity of the industry.

In fact, according to relevant information, there are already about 20,000 users rushing to buy it. When it came to these plans, however, most investors did not win the lottery, onlyA small number of people successfully subscribed. Of course, in response to this, CSPR (Casper) has come up with a fourth plan, and more than 10,000 people have already subscribed for this plan.

❼ What are the seven major blockchain applications that will affect the future world?

Blockchain is the return of value to the Internet.
In 1989, Berners-Lee developed the World Wide Web. The World Wide Web was founded on the principles of openness and fairness. But today, 28 years later, various forms of monopoly have begun to appear on the global Internet, and the principle of openness and transparency on the Internet has been trampled on without restraint.
In China, the Internet has officially entered the era of "the United States and the Soviet Union competing for hegemony", with Tencent and Alibaba almost forming a monopoly. Some platforms have experienced leaks of user privacy one after another. Recently, it has been reported that two well-known companies are competing for user data, etc. To change all this, a new technological force is urgently needed, and it is against this background that blockchain emerged.
Explained from a technical perspective, blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms.
The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system. In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and cryptographically ensures a distributed ledger that cannot be tampered with or forged.
Broadly speaking, blockchain technology uses block chain data structures to verify stored data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure the security of data transmission and access. A new distributed infrastructure and computing paradigm that uses smart contracts composed of automated script code to program and manipulate data.
From this point of view, blockchain application projects that can affect the future world must have the following common characteristics:
1. The field has extremely high demand for data security
2. The field has extremely high requirements for data privacy
3. The computing process needs to be traceable and non-tamperable
4. It can reduce social costs
5. Open attitude, everyone can contribute and participate
6. Have its own independently issued token
7. The industry has been highly prosperous in the Internet landscape
Through sufficient industry data research and extensive sampling research, we list the following eight areas that can change the world. Blockchain application directions and outstanding representative projects.
1. Finance
The core value of blockchain application in the financial field: promoting anti-money laundering and customer identity review.
In the innovation and application exploration of blockchain, finance is the most important field. Blockchain technology has broad applications in many aspects such as digital currency, payment and settlement, smart contracts, financial transactions, and Internet of Things finance. prospect.
Take Taobao shopping as an example. The payment process requires Alipay.Achieve trustworthy guaranteed transactions, but because Taobao and Alipay belong to the same company, this credit foundation is controlled by Alibaba itself. If the Alipay guarantee platform is replaced by a "trustworthy super system" to make transactions intuitive and safe, there will be no need for third-party guarantees. The emergence of blockchain can make this idea a reality.
Bitcoin is currently the most widespread and successful application of blockchain technology. Because of its non-tamperable timestamp and network-wide publicity, it has been widely trusted by financial industries such as banks, securities, and insurance. Recently, It has skyrocketed in recent years, and Bitcoin has even become legal currency in many countries.
2. Games
The core value of the blockchain application game field: returning game rights to game players.
The technical features of blockchain technology, such as decentralization, smart contracts, and asset transactions, can well solve the current problem of privacy leakage of game data and user data in the gaming industry, promote the preservation of the value of virtual digital currencies in games, and enable users to Fair value sharing with game development platforms.
Abroad, blockchain technology has been widely used in game currency payments. For example, Fragoria, a game with eight million players, has launched GameCredits’ blockchain payment gateway, providing the first cryptocurrency payment solution for the gaming industry.
3. Socialization
The core value of the social field of blockchain applications: allowing users to control their own data and prevent privacy leaks.
Think about why we always receive similar advertising pop-ups on other social platforms after browsing a certain shopping website. This is because data privacy is shamefully trafficked by monopolized big data platforms.
The purpose of applying blockchain technology in the social field is to shift the control of social networks from centralized companies to individuals, realize the change from centralization to decentralization, and firmly grasp the control of data. In the hands of the users themselves.
Israeli light social APP software Synereo fully guarantees user privacy and security with the help of an anonymized blockchain network and its embedded token mechanism. At the same time, tag tokenization and personalized pricing are used to help people reshape their social network image, relationships between people, identity and cognition.
4. Copyright
The core value of blockchain application copyright: reshaping the protection of intellectual property.
Blockchain technology records all transactions in blocks, and the records cannot be tampered with, so all transactions can be tracked and queried, ensuring transaction transparency on the blockchain and avoiding Users on the Internet illegally use content protected by intellectual property rights. For original creators, this is a more convenient, safer and cheaper way to protect copyright.
At present, blockchain technology is mostly used in the copyright protection of digital music. The online music platform PledgeMusic has announced a comprehensive blueprint for a global decentralized account book and fair trade music database, which can fully solve the issues of ownership, payment and transparency.
5. CloudComputing
The core value of blockchain application cloud computing: promoting the construction process of public trust infrastructure.
China Academy of Information and Communications Technology believes that the combination of blockchain and cloud is also an inevitable trend. There are two models for the combination of blockchain and cloud, one is blockchain on the cloud, and the other is blockchain in the cloud. The latter one, namely BaaS, Blockchain-as-a-Service, refers to the cloud service provider directly providing blockchain as a service to users.
In the future, cloud service companies will increasingly integrate blockchain technology into the cloud computing ecological environment. By providing BaaS functions, they can effectively reduce the deployment cost of enterprise application blockchain and lower the initial threshold for innovation and entrepreneurship. .
6. Sharing Economy
The core value of blockchain application in the field of cloud computing: building user trust for the platform.
Blockchain is a distributed and consistent storage system that realizes a transparent and true credit management system under the P2P business model. The core is decentralization and trustlessness to crack the trust pain points of the sharing economy. P2P online lending, second-hand car trading, accommodation sharing and other sharing economy segments have already begun to be tried.
By using smart contract technology, blockchain can automatically perform operations that meet certain conditions, and can also enable more goods to be "shared", significantly reducing the cost of contract establishment and execution.
Tencent is applying smart contracts to bicycle rental, house sharing and other fields. If this smart contract is applied to today's popular bicycle sharing field, it may bring new changes to the entire industry.
7. Digital Advertising
The core value of blockchain application in the field of digital advertising: achieving precise advertising and ensuring that user privacy is not violated.
The natural advantages of blockchain technology in terms of data non-tamperability, decentralization, and security indicate that it has natural advantages in grafting with digital advertising. Smart contracts can effectively improve the efficiency of advertising transactions while combating digital advertising fraud.
metacrypto metadata advertising chain is the world’s first mobile advertising platform based on blockchain technology. MetaCrypto adopts a decentralized business model and does not rely on any centralized intermediaries or the troubles of bidding rankings to achieve freedom. Submit an online advertising contract, and there is no need to worry about the delivery effect being tampered with by any link or being falsely delivered by the channel party.
Users set personalized metadata on their own private devices. Private and sensitive information will only be kept on their own devices. Only part of the metadata that can be made public for contract matching will be synchronized by the business blockchain. , while protecting the privacy of each user, the user can locally trigger the advertiser's ad playback contract and obtain certain additional rewards.

❽ Four major highlights in the blockchain field in 2022｜Interface Prophet⑯

There is a core proposition about the "Impossible Triangle" in the blockchain field, namely security Sex, sexcapabilities and degree of decentralization. This proposition is the foundation of the evolution of blockchain technology. Whether it is Bitcoin, Ethereum, or the vigorously developed alliance chain, it is essentially a trade-off between the above three elements.

As Ethereum’s core position among blockchain developers is determined, performance has gradually become a bottleneck for its development. Therefore, in the foreseeable 2022, improvements in performance and efficiency will be a long-term and critical issues.

Based on the Ethereum ecosystem, to improve performance within the limits of the "Impossible Triangle", the current path has been clear. The first one is the Layer 1 level, that is, other public chains share the burden of Ethereum. Data pressure.

One of the major trends in 2021 is the increased use of Layer 1. The space is currently dominated by Solana, Avalanche, Terra and Binance Smart Chain, each with a growing ecosystem. The value has exceeded 10 billion US dollars.

The second type is Layer 2, which is based on the Ethereum main network, but transfers settlement to the second layer network to improve efficiency. This is what Ethereum is working on, Layer 2 is often called rollups because they "aggregate" or bundle transactions together and execute them in a new environment before sending updated transaction data back to Ethereum.

As for the most critical data verification link of the blockchain, Layer2 currently has two technical solutions, one is called "Optimistic rollups" and the other is called "ZK Rollups". Both technical routes have teams developing corresponding networks and have ecological support, such as Arbitrum, which chooses "Optimistic rollups", and dYdX, which chooses "ZK Rollups".

Between Layer1 and Layer2, there is another solution called "side chain", which is partially compatible with the Ethereum main network, but does not belong to Layer2. They are specially used to deal with the excess of Ethereum. capacity, rather than competing with Ethereum as a whole, and hosting Ethereum applications in a complementary manner.

Starting with DeFi, which currently has the most active users, according to statistics from DeFi Lama, the amount of DeFi locked on Ethereum has exceeded 100 billion US dollars, and other public chains such as BSC, Solana, and Avalanche have also Attracting nearly US$49 billion in funds, it has become a very active financial scene.

Although the data of many public chains is quite large, different chains are like data islands, and assets on different chains cannot be freely exchanged. In addition, many emerging public chains are not as developed as Ethereum and lack many foundations. Facilities, such as stablecoins and NFT gamesDrama Wait.

Therefore, assets on other chains need to be introduced into one's own public chain through cross-chain. Among the currently commonly used cross-chain methods, in addition to cross-chain currency withdrawals in centralized institutions such as exchange wallets , the most common ones are various decentralized cross-chain asset bridges.

For cross-chain bridges, the most important issue is how to reach consensus, which is largely related to the security of investors’ assets under custody. For now, the security of centralized exchanges Cross-chain bridges are the most convenient type of cross-chain bridge for users. However, cross-chain bridges in centralized exchanges have the problem of single points of failure. In addition, current cross-chain bridges are gradually moving towards non-custodialization. Development is to further protect the security of users’ assets.

The full name of DAO is "Decentralized Autonomous Organization", which is a management model that attempts to get rid of the traditional bureaucracy and uses blockchain technology to complete autonomous operations. organizational form.

Decentralized Autonomous Organizations (DAOs) enable global coordination of individuals using blockchain-based governance. DAOs can be used for many purposes, including managing the operations and capital of a blockchain project (MakerDAO), managing investment capital (The LAO), managing the use of game assets (YGG DAO), coordinating cultural groups (Friends With Benefits), or coordinating purchases Asset (Constitution DAO).

The number of DAOs included in the deep website has reached 187, with total assets under management exceeding US$12 billion and covering more than 1.6 million members. Although in the blockchain field, this is not a huge amount of data. But institutions including Sequoia Capital are beginning to take notice of this new term.

The market value of cryptocurrencies officially exceeded US$2 trillion in 2021 and is now at US$2.5 trillion, an increase of 175% from the beginning of the year. Along with the explosive growth of market value, financing in the encryption field has also increased rapidly. According to statistics, there were 1,529 publicly disclosed primary market financings in the encryption industry in 2021, totaling approximately US$32.6 billion, with a year-on-year growth of an exaggerated 814.2%.

However, equity financing in the crypto field is different from other fields. Under the "VIE" structure, the main exit channel for traditional VC funds is for companies to land on the secondary market for IPO.
