From the First Institute of the Ministry of Industry and Information Technology and the Ministry of Public Security Institute of Information and Communications Technology, National Monitoring and Management Platform for New Energy Vehicles, German Automobile Manufacturers Association, FAW, SAIC, Changan, Dongfeng, BAIC, GAC, Great Wall, Geely, Chery, NIO, Ideal, Xpeng, Tesla, Thirty-two intelligent connected car-related companies and scientific research units, including Volkswagen, Daimler, BMW, Audi, Huawei, Bosch, China Automotive Industry Corporation, Shanghai Automotive Inspection, NavInfo, Horizon, Energy Chain Technology, and Momenta, participated in the discussion. At the meeting, various companies conducted in-depth discussions on data security supervision, industry development, private data privacy protection, and data trustworthiness. The meeting believed that data security is the core of industry development, and the industry urgently needs to establish a trustworthy system for intelligent connected vehicle data between governments, enterprises, and users; at the same time, market advantages should be fully utilized to promote the use of new technologies and new means to improve the system .

Dr. Wang Yao, Assistant Secretary-General of the China Association of Automobile Manufacturers and Director of the Technology Department, gave a special introduction on the issue of trustworthy storage of intelligent connected vehicle data. The China Association of Automobile Manufacturers and relevant enterprises have jointly launched the "Automotive Data Trusted Storage" to the entire industry after more than three years of exploration in order to solve the problems of large data volumes, high storage costs, difficulty in traceability, and difficulty in ensuring data security in the era of intelligent connected vehicles. Certification Blockchain Platform”.

The platform takes advantage of the unique data anti-tampering and traceability features of blockchain technology to provide enterprises with trusted data storage services by relying only on uploading data hash values ​​(no need to upload any original data) . At present, the platform has been completed and can provide related services to member companies free of charge from now on.

『二』Ma Jinghua: 5G and blockchain are the best tools to increase influence

In the forum session of this summit, guests on-site discussed The theme of "Media Trends and Trends" was conducted in-depth discussions, and wonderful interpretations were made based on their respective corporate characteristics and industry experience. Ms. Ma Jinghua, former Vice President of Public Relations of BMW Brilliance, Brand Director of Volkswagen, and now Vice President of the International Department of Dalian Tiansi Museum Education Group, said:

I strongly agree that any business must have strategic goals. Its vision, mission, and goals must be clear. 5G and blockchain are both technologies, and the priorities must be clear. Especially in the future, brand communication is very important. The basic principles of brand building, the relationship between elements and consumers, how to maintain the value of the brand, how to measure the value of the brand, these basic business rules will not change. I hope everyone Calm down and understand these rules, learn these things and store them in your mind. Then you will not lose your direction when the big waves come, let alone be dizzy by the colorful techniques.

Specifically, 5G is characterized by low latency and high transmission speed, which places high demands on the quality of media personnel and public relations personnel. Then there are the changes in content distribution channels and methods, and everything brought by 5GThe Internet, everything is a media, smart cities, smart homes, everyone has become a media. In this case, how do you influence the public and spread your message? Everyone should think about it from a higher level, because of its low latency and high speed, coupled with the rise of short videos, the customer experience has become higher and the requirements have become higher. How can public relations and media adapt to it?

As a media company or media personnel, you must have a clear strategy. What should my company do when both technologies are intertwined. According to my personal opinion, whether it is 5G or blockchain, it is actually the best tool to increase influence. We seize this opportunity, follow this trend, and take advantage of the trend to strengthen ourselves. This is an opportunity, a time to build influence, which is rare.

I studied a little bit about blockchain because one of my classmates wrote China’s first book on the popularization of blockchain technology. As Mr. Fu just said, the core of the blockchain is the protection of the original creators. The protection of the original creators and their works gives the original creators a platform and standard for measuring their self-worth and self-products. This provides a great protection for the creation of media and the creation of content by media practitioners. In the future, as long as everything we write is good and unique, many people will buy it and give you likes. This is actually very common in the United States.

Blockchain is also helpful for distribution channels. Anything you write in a rough way will have traces, and the good things you write will also be confirmed, widely quoted, and create higher value. You have the right to be yourself. Therefore, media companies must create a blockchain strategy as early as possible, take advantage of the trend, and seize this opportunity.

『三』 Five major factors that can promote the prosperity of blockchain technology in the future

The wind of change is blowing strongly. Starting from the Bitcoin craze at the end of 2017, Bitcoin futures contract trading reached a climax . The panic subsided a bit and buzzwords like blockchain, cryptocurrency and Bitcoin slowly faded from the headlines. But now the next phase for Bitcoin is the legalization of the asset class and the promotion of blockchain technology. Behind the market’s recent headlines about the trade war with the United States, a turf war has begun in the blockchain world. This is not a company changing its name to attract new investors, but some mature industries using this technology to cut costs and improve profit margins. Major companies like Walmart, UnitedHealth, and BMW have been adapting blockchain technology to suit their needs. It’s not just concepts, the practical applications of blockchain are already creating huge changes in industries around the world. The revolution has just begun, and when researching the cryptocurrency ecosystem, you'll find that there are many ways to invest in blockchain.

1) "Noisy Picks and Axes" and Miners

During the gold rush, the really rich people were those who sold picks and axesAx man. That is, these companies provide speculators with the tools to go out and find fortune. In the cryptocurrency world, this refers to companies that produce chips and hardware used in mining operations. Includes many semiconductor companies.

And the miners themselves. Miners confirm transactions between nodes by solving cryptographic problems and are then rewarded in cryptocurrencies. We’ve already seen publicly traded companies “mine” cryptocurrencies. These companies mine the tokens and then immediately sell them on the open market and pass the proceeds on to shareholders. Think of them like the pipeline companies of the energy industry. These companies are currently small but may become larger over time.

2) Cloud infrastructure

No industry relies as much on cloud technology for development as blockchain. The need to distribute the ledger globally without centralized ownership or regulatory trading authority takes full advantage of the cloud. However, the cloud still faces risks here because blockchain technology can distribute storage globally, thus countering the centralized nature of traditional cloud services. Still, the industry can adapt technology to benefit.

3) Payment processing and lending

One of the most disruptive industries for blockchain is payment processing. Unlike traditional financial intermediaries, blockchain technology supports a distributed, open, public ledger in which transactions are confirmed by other nodes in the chain and charge higher fees than those from traditional processors. The typical fees are much lower.

Blockchain technology is also ideal for lending, allowing it to spread risk across thousands of loans in an instant, regardless of the size of the lender. We are just the tip of the iceberg on this stage.

4) Investment firms, business development firms and consulting firms

There will be a wave of companies looking for ways to integrate blockchain technology into their existing businesses. Large consulting firms have begun offering services to help companies integrate new technologies. Gartner even developed a website specifically for this purpose.

Some public companies are acting as incubators for other emerging cryptocurrencies. There are currently over 1,600 cryptocurrencies in the world. These investors and business development firms invest in promising cryptocurrency technology companies before the technology becomes mainstream.

5) Futures and ETFs (Exchange Traded Funds)

The legalization of Bitcoin continues as futures contracts begin trading on two major U.S. exchanges. Soon, Bitcoin and Ethereum ETFs will also be officially regulated. Meanwhile, investors have been using GBTC as a proxy. As mentioned earlier, Goldman Sachs will soon open its trading desk, further evidence ofThe legitimacy of cryptocurrencies as an asset class.

Conclusion

There is no doubt that blockchain will have a huge impact on almost every industry you can think of. In fact, experts predict that the sector’s value will surge 8,500% to $60 billion by 2024.

Just like in the early days of the Internet, some companies will reap huge benefits. Others are just ephemeral. We cut through the gimmicks and hype to shine a light on the powerful, often little-known companies driving blockchain technology. Jianghui Shengxing Network Technology is a professional blockchain R&D company that provides overall blockchain solutions and uses the current popular blockchain technology to truly realize blockchain development. As a professional system development company, we have 5 years of system development experience and two years of blockchain development. We have very mature development experience and are constantly improving our technology and service quality. Solve customer needs to the greatest extent possible. If you have blockchain system development, blockchain technology research and development, various blockchain system development, blockchain settlement system development, blockchain APP development, blockchain game development, blockchain transaction system development, district If you need blockchain solutions, blockchain project development, blockchain financial system development, blockchain business model system development, blockchain payment, blockchain application development, etc., you can contact me.

『四』What kind of sparks can be created when cars meet blockchain?

Speaking of blockchain technology, it became familiar to everyone almost overnight. Words have become a technology trend pursued by many industries, and the automotive industry is no exception.

According to the MOBI statement, the alliance aims to create common standards and APIs (application program interfaces) among alliance members, seeking to establish a new digital mobile ecosystem that enables Businesses and consumers have security and sovereignty over their driving data, manage ride sharing and vehicle sharing transactions, and store vehicle identity and usage information.

However, Zhu Youping also pointed out that the scale of automobile companies is relatively large, and the alliance blockchain will have a more profound impact on automobile companies. However, the biggest difficulty in the current application of blockchain technology in the automotive industry is the This understanding is insufficient. For this reason, alliances like MOBI still need more members to join. On the one hand, it is to make more car companies aware of blockchain technology, and on the other hand, it is to allow the data of car companies to be shared.

As a technology that has just emerged in recent years, blockchain is still in its early stages of development. Whether it can be used on a large scale in the future is still unknown. Even if it can be used on a large scale, it will take a long time. time. But it is undeniable that the emergence and application of blockchain technology have given the automotive industry more possibilities for development.

『五』BMW one articleYou have an in-depth understanding of what Defi is

DeFi is the abbreviation of Decentralized Finance, also known as Open Finance. In practical terms, this means decentralized protocols for building open financial systems designed to allow everyone in the world to conduct financial activities anytime, anywhere.

In the existing financial system, financial service control is regulated by a central system, whether it is the most basic transfers and deposits, loans or derivatives transactions. DeFi hopes to establish a transparent, accessible, and inclusive peer-to-peer financial system through distributed open source protocols to minimize trust risks and make it easier and more convenient for participants to obtain financing. Compared with traditional centralized financial systems, DeFi platforms are disruptive. Not to mention the unique advantage of blockchain that does not have a centralized server, through the DEFI project, anyone can create financial products built from protocol cooperation products, triggering huge financial innovation products with network effects. DeFi is like attaching flowing wings to assets, spewing out countless constant gameplays.

The rise of Defi

A few years ago, the blockchain industry did not have the concept of Defi. It only took a few years for Defi to rise from an unknown to the "overlord" of the blockchain industry. year time. There are already many articles about Defi on the Internet. I fully acknowledge the potential and bright future of Defi.

The origin of Defi

DeFi itself is a concept and architecture, which is the same as the application of "blockchain technology" in financial technology. The concept of Defi comes from Brendan Forster, the co-founder of the lending product Dharma. He published an article on Medium on August 31, 2018, explaining the concept of DeFi. The article involves four conditions that DeFi must meet:

Decentralized Blockchain: decentralized blockchain

Finance Instry: financial industry

Open Source: open source code

Developer Platform: development Platform

How does DeFi work?

DeFi solutions are powered by blockchain technology and use the most powerful programmable digital assets such as Bitcoin (BTC) and Ethereum (ETH). These digital assets have monetary value mainly because of their value storage properties. Because these assets are programmable, they can be locked onto smart contracts as collateral (similar to residential mortgages).

We can also do a lot of interesting things with provable lock values. Through this collateral, loans are made in the form of so-called “stablecoins”. "Stablecoin" is and the beautyA digital currency associated with world currencies such as the Yuan. We can exchange these stable assets for other digital assets, use them online, or earn interest on lending protocols. It is also possible to do higher level work beyond the scope of financial products we know today.

The general meaning is that digital reserve assets are used to mortgage innovative financial products that are completely digital and disintermediated. You can directly interact with the code anytime and anywhere without the need for an intermediary company. This is a very representative change.

Why is DeFi so popular?

DeFi is still in its infancy as a concept and ecosystem, providing us with new financial services and currency models, new models that are fully collateralized, transparent, uncensorable, and composable. It is clear to us that there are some inherent flaws in the world's financial system, mostly due to opacity and excessive borrowing. I do not believe that the global financial system will be completely replaced by crypto-based alternatives, but do believe that it will exist in parallel with crypto solutions and provide alternatives for those seeking crypto solutions.

From a user perspective, DeFi solutions also have some interesting features. First of all it is non-permissive, that is, it does not require anyone's approval to perhaps use these products. It doesn't require opening an account anywhere, sharing a copy of the passport and my money in the bank is actually in the bank. Instead, it uses its own cryptocurrency wallet to interact directly with the code, and the interaction is anonymous, real-time, and can be started at any time.

The main application directions of DeFi

1. Pledge

The blockchain network based on the Proof of Stake (PoS) protocol algorithm requires the verifier to pledge part of the digital currency funds. , to create, suggest, and vote on the network. In exchange for maintaining the network, validators under the PoS mechanism can earn rewards by staking their digital assets.

To support this consensus algorithm and earn passive income (similar to a bank deposit account), developers can create DeFi dApps, where decentralized product solutions such as staking pools and "staking services" can be used solution.

Examples of DeFi staking applications:

StakeWithUs: “Staking as a Service” based on PoS protocol

Mythos: Validator service for Cosmos and Loom networks< /p>

Dokia Capital: Professional institutional-level staking service

BMWEFT pledge mining: pledge mining means that users entrust BMWEFT to nodes through smart contracts, and the contract will be based on the overall pledge rate of users. Provision of BMWEFT pledge income. By accepting the pledge entrustment application from users holding BMW coins, the node safely stores the assets in the BMWEFT pledge contract, and users canAs for obtaining income, the annualized pledge rate at this stage is roughly around 15%. Since the target inflation rate for the issuance of BMWEFT is 3%, the later pledge rate will be adaptively adjusted according to the overall pledge amount.

2. Payment service

Allows anyone to create and trade their own digital tokens using Bitcoin blockchain data. Payment-type decentralized financial applications generally have their own digital currencies. Users can use them to conduct transactions and provide wallet addresses. Users can hold these digital currencies. Decentralizing payment services is often a good option for unbanked users and for digital currency enthusiasts and financial institutions.

Examples of DeFi payment services:

Whisp: a decentralized payroll solution with digital currency payment capabilities

Lightning Network: a network built on Bitcoin, Using smart contracts to enable low-cost and fast off-chain payments

Request Network: a decentralized network that allows users to request, verify and execute payments

BMW Flash Cash: BMW Flash Cash It is one of the many decentralized applications launched by BMW relying on Ethereum. BMW Flash Exchange can provide users with convenient and safe currency-to-coin exchange operations, realizing mutual transactions and exchanges between different currencies.

BMW Flash Exchange is a decentralized exchange "BMW DEX" built based on the pain points of centralized exchanges such as the time required for deposits and withdrawals, low transaction data security, and high transaction fees. BMW Flash Swap based on the market maker's bilateral bidding mechanism is constructed by a smart contract. The user's digital assets are initially stored at the user's address. The user interacts with the smart contract during transactions, and the smart contract executes the exchange of the user's digital assets, so it is completely decentralized. The centralized application eliminates the security issues caused by centralized exchanges. BMW Flash Token adopts a passive quotation model, leaving room for arbitrage. At the same time, there is no handling fee for user transactions and only a certain amount of fuel fee is charged.

3. Lending

Decentralized lending is a core application that attempts to decentralize the economy. Like now, people have to go to a bank to get a home loan. The core goal of decentralized lending is to make more loans available to people from lenders and democratize the lending process overall. One example of decentralized finance currently being experimented with in the lending space is the Dharma Protocol. It is built on the Ethereum blockchain, Dharma allows participants to lend various forms of collateralized bonds. Currently, lending products are the hottest applications in the DeFi market. In terms of market price, two DeFi dApps, MakerDAO and Compound Finance, account for 77.5% of the total market share.

Using these platforms, you can borrow digital currency as collateral, or lend digital assets to other users to earn interest.. Platforms like Maker and Compound have other products (stablecoins, etc.) and DeFi services built into dApps.

BMW is expected to launch the BMW mortgage lending platform in 2022Q3 to provide users with a decentralized digital currency banking system. Users can deposit qualified digital currency assets, earn interest and use deposit assets as collateral. Obtain a loan line, which allows users to access digital currency assets that meet the requirements. We will obtain various other price data from Chainlink to calculate the value of users’ assets and conduct decentralized liquidation of under-collateralized assets. This will bring an extremely high level of security to users and ensure that the mortgage rate remains adequate.

4. Decentralized ETF

The financial derivatives leveraged ETF issued by BMW is essentially an anchored financial derivatives spot (ETH, BTC, LINK, silver , crude oil, etc.) price changes in index funds.

The series of digital currency leveraged ETFs currently issued by BMW will fluctuate according to a certain leverage ratio with the rise and fall of related financial derivatives (ETH, BTC, LINK, silver, crude oil, etc.).

BMW will further explore the possibility of implementing more traditional financial scenarios through DeFi. For example, we hope to obtain specific financial market index data and issue decentralized ETFs through BMW.

The BMWETF brand will release a series of DeFi Dapps, including lightning exchange (DEX) and pledge mining (BMW Staking); decentralized games such as lossless lottery and BMW pass red envelopes.

DeFi Dapp is the core business of BMWETF. The core of DeFi application is to provide safe and reliable value for assets. If the data source of asset price is unreliable, such as being manipulated or the price update is not timely, it will have a direct impact. to the normal operation of the application. Therefore, a safe and reliable decentralized oracle system can provide timely and reliable asset prices while ensuring the end-to-end security of Dapp, and plays a key role in this process.

5. Decentralized exchanges

Users can trade digital assets such as Bitcoin and Ethereum. Decentralized exchanges were created to solve the problems of centralized exchanges. In centralized exchanges, users cannot control their own property because they do not have their own private keys.

BMWETF is such a decentralized financial application. It is a comprehensive DeFi application platform with digital currency ETF as its core product.

BMWETF is a decentralized trading platform deployed on the Ethereum mainnet. All transactions are executed through smart contracts, allowing users to trade digital assets while controlling their own private key trades.

Enter the BMWETF Dapp page and select products (such as lightning exchange, ETF, pledge mining...) for trading. Users who already have an Ethereum encrypted wallet can directly access https://BMWBE.COM through the encrypted wallet (copy the link and access it from the imtoken wallet browsing page).

Mia Niu, CEO of BMW Health Platform, said: Decentralized finance is an expansion of financial science and technology and is also the entry point for traditional finance and blockchain in the future. The most important thing is that decentralized finance is already underway and is a science, technology and service that everyone can use. As a DeFi comprehensive application platform, the BMW Big Health Platform is committed to blockchain technology exploration, application research and talent training. It uses human vision as the driving force to increase the popularity of blockchain applications and enhance society’s awareness of blockchain. , to promote the traditional Internet to accelerate into the era of value Internet. Of course, we can also look forward to BMW establishing a more comprehensive DeFi Dapp in the future, so that blockchain technology can truly benefit the general public.
