❶ What are the benefits of blockchain + supply chain in industry applications

Application prospects of blockchain in the Internet of Things and logistics fields Blockchain in the Internet of Things and The logistics field can also be naturally combined. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered to be a promising application direction of blockchain.
Skuchain has created a new supply chain solution based on blockchain to synchronize commodity flow and capital flow while mitigating the problem of counterfeit goods. London-based blockchain start-up Provenance provides supply chain traceability services to enterprises. By recording the entire process information of the retail supply chain on the blockchain, it can achieve the retrieval and tracking of product materials, raw materials and product origin and history information. , improve the transparency and authenticity of information in the supply chain. A German start-up company Slock.it has made a smart lock based on blockchain technology, connecting the lock to the Internet and controlling it through smart contracts on the blockchain. Simply transfer money to the smart contract account through the blockchain network to open the smart lock. When used in hotels, guests can open the door easily. This is the real sharing economy!
Not only in supply chain management, but also in the financial field, intelligent manufacturing, culture and entertainment, financial services, medical health, and IP copyright , education, sharing economy, communications, social management, charity, social employment, and e-government can all be widely used.
At present, domestic Internet and IT are involved in the blockchain industry, and have begun to develop or launch a series of solutions for basic application cases. In the current development trend, integrating blockchain technology into smart life, the Internet of Things and other fields, integrating massive physical business application scenarios, carrying out blockchain + physical industry projects, and realizing the physical transformation and upgrading of the physical industry are among the most promising. One of the representative blockchain application directions.

❷ How to truly understand “blockchain”

The following uses the blockchain content publishing platform DECENT as an example:
If you create some content, These contents may be: articles, music or other interesting things. You want to share these "works" with the world through TV, websites, micro-blogs, etc., but no matter what it is, it seems that you must have a The "media" can make your "work" public.
At present, this may be the only way, but it also brings problems - when you disseminate your work through the media (third party), you need to go through its internal review, and they will determine your work. Whether the content is good enough and caters to the taste of the readers, in which case, what you create may be affected and put in a "certain angle" or "adjusted to suit the interests of that third party or agenda".

❸ Has China’s blockchain industry chain been formed?

The "2018 China Blockchain Industry" released by the Information Center of the Ministry of Industry and Information Technology of China on the 20thThe White Paper states that China’s blockchain industry is currently in a stage of rapid development, and the industrial chain has initially taken shape.

Judging from the distribution of blockchain industry subdivisions, as of the end of March 2018, the largest number of industry application service companies in the blockchain field were The number of companies providing application services in the financial industry has reached 86, and the number of companies providing application services mainly for the real industry has reached 109. In addition, the number of related companies in the fields of blockchain solutions, underlying platforms, blockchain media and communities is more than 40.

❹ The third generation blockchain will make up for the Defi loopholes left by Ethereum

Since the ETH 2.0 upgrade is still several years away from full release In months and even years, third-generation blockchain protocols are quickly catching up to replace Ethereum as the “go-to” hub for dapps and defi.

Although many people may have only recently discovered it, blockchain technology has been around long enough to evolve from first-generation protocols to second-generation protocols and now to its third generation protocol.

The first generation of blockchain began with Bitcoin, an alternative to the hegemony of centralized financial services. It laid the foundation for a decentralized financial ecosystem, but the Bitcoin network offers limited functionality, requires enormous computing power to run, and suffers from a severe lack of interoperability.

This led to the emergence of Ethereum in 2015, marking the dawn of second-generation blockchain protocols. As Vitalik Buterin introduced smart contract functionality on the blockchain, it triggered a paradigm shift that allowed cryptocurrencies to transition from financial instruments to more practical purposes.

Ethereum opens the door to decentralized finance (defi) by enabling "conditional transfer" of data and value on the chain. Since then, Ethereum has been growing like crazy, solidifying itself as the go-to platform for launching dapps, NFTs, and defi protocols.

Developers and adopters embraced Ethereum and started generating their own ERC20 tokens, so many social media platforms started talking about "flippening" - the terms in which ETH would exceed the market cap of BTC.

However, despite its success, problems soon became apparent on the Ethereum blockchain. As new projects enter the Ethereum ecosystem in large numbers, the network begins to face scalability issues. Gas fees skyrocketed and limited transaction throughput became a daily problem.

Ethereum creator Vitalik Buterin also expressed his doubts about Ethereum’s ability to scale, saying:

While the proposed Ethereum 2.0 upgrade promises solutionsTo resolve the issues currently clouding the Ethereum network, things didn’t go as planned. The first phase of ETH 2.0, initially slated for a 2019 launch, begins in December 2020. There are still two phases left, and a full launch before 2022 is highly unlikely.

Therefore, it is not an exaggeration to claim that the network still has a long way to go before realizing its core vision of becoming the world's "decentralized computer."

Despite the innovations brought by Bitcoin and Ethereum, these chains are plagued by their own scalability and efficiency issues. At the same time, both networks require significant computing resources to run. All of this results in a perpetual cycle of painfully slow throughput and exorbitant costs.

Many local 2-level scaling solutions have been developed to overcome the inherent problems of Bitcoin and Ethereum, each with varying degrees of success. Layer 2 solutions solve interoperability and scalability issues to a certain extent, but core issues related to consensus mechanisms and mining have yet to be resolved.

This is where the third generation of blockchain comes in. While some third-generation protocols complement existing blockchain networks, others are entirely new blockchains with a wide range of features and functionality. From multi-layer architecture to innovative consensus mechanisms, third-generation blockchain protocols are not only fully capable of solving emerging scalability issues, but are also highly interoperable, fast and cost-effective.

It is undeniable that the defi craze happened because of Ethereum, and Ethereum still dominates the defi market. However, with the emergence of newly defined projects based on third-generation blockchain protocols, Ethereum’s authority will undoubtedly be challenged.

As defi continues to expand its market, the next "Defi boom" is likely to come from emerging industries that are more agile and focused than early blockchain network innovations. That said, as the crypto world lays the groundwork for the “next big flip,” promising projects are lining up for newer blockchain technology.

In terms of market dominance, Cardano, Solana, and Polkadot lead the way. Each platform offers a range of capabilities, which is why a consortium of new projects is lining up to start building their ideas on these platforms.

For example, Cardano’s stablecoin and defi hub Ardana enables Cardano to expand into the defi space. The platform and its constituent protocols were designed from a defined macro perspective to provide users with the functionality they need to help maintain all types of decentralized economies on the Cardano chain. It will serve as a financial foundation layer by adopting historically proven composability, capital efficiencyand stable protocol model to support Cardano’s decentralized economy.

Ardana will soon launch dUSD as part of its strategic roadmap. This verifiable, on-chain mortgage-backed stablecoin will help users put their ADA and other supported assets to use. The platform will also launch its AMM dex (decentralized exchange) Danaswap for stable multi-asset pools. According to the Ardana team, Danaswap will offer capital-efficient swaps while targeting minimal slippage and enable liquidity providers to take advantage of low-risk yield opportunities.

Another ambitious initiative is Acala, a Defi liquidity center that leverages the built-in capabilities of the third-generation blockchain protocol Polkadot. Currently, almost all stablecoins are built on the Ethereum network, limiting adoption and usage. Acala hopes to change this reality by leveraging Polkadot’s speed, cross-chain interoperability, and cost efficiencies to provide a defi hub with built-in liquidity and ready-made decentralized finance applications.

Likewise, Acala claims to settle transactions at a fraction of what other networks require, establishing a numerical advantage in the defi race. The platform will support small gas fees that are minimally affected by transaction complexity through Polkadot’s weight-based fee model. Additionally, Acala will introduce an “algorithmic risk adjustment” feature that will automatically modify the risk parameters of its lending protocols, including interest rates and collateral ratios.

Finally, in the ongoing battle for defi market share, Atani, the all-in-one crypto trading platform built on the Solana blockchain network, is another heavyweight contender to monitor. The platform offers free crypto trading tools and partners with top exchanges such as Kucoin, Binance, Okex, Bitfinex, Poloniex, etc. to provide users with lower trading fees.

Atani recently launched a new dex aggregator on Solana to provide order routing capabilities while providing add-ons such as portfolio tracking, price alerts, technical analysis, and more. With this aggregator and the embedded nature of Solana, Atani’s plan is to reduce friction between the decentralized defi ecosystem and provide liquidity from cexs (centralized exchanges) and dexs to the Solana ecosystem while ensuring multi-chain support .

When it comes to tapping into defi’s true potential, we haven’t really scratched the surface yet. Web 3.0 is evolving and the global village is getting smaller. At the same time, the defi service hasIt’s revolutionary for the world’s unbanked and underbanked, who need more space to expand, just as existing protocols push network capacity limits.

From an unbiased perspective, Polkadot, Cardano, Solana, and several other third-generation blockchain platforms provide much-needed solutions to the scalability and interoperability that hinder traditional chains. They are faster, more secure, more cost-effective and low on resource consumption, positioning them as an all-in-one solution that can broadly benefit the entire cryptocurrency industry. With the debut of Ethereum 2.0 still a long way off, third-generation blockchain protocols are already here to do the heavy lifting and take defi to the next level.

Which network do you think will win the defi race? Let us know in the comments section below.

❺ When will the national standards for blockchain technology be completed

my country has begun to establish a national standard for blockchain to promote the construction of a blockchain standard system from a top-level design, which is expected to be completed by the end of 2019 at the earliest.

In this regard, Zhao Wu, founder of Beijing Huashun Xin'an Technology Co., Ltd., also said that although blockchain has disruptive technological potential, we must realize that blockchain The blockchain is still in its infancy and is far from reaching the stage where it can disrupt the world.

Yu Kequn emphasized that an independent and controllable blockchain network is not technically controlled by others, but can also promote the healthy development of the blockchain. Security is the future life of the blockchain, and only its own security can bring blockchain technology to fruition. This requires us to pay equal attention to the development of its security attributes while developing blockchain technology, and even develop it ahead of time.

In this regard, Li Ming also said that an important part of the standard is the standard of information security, which also shows the importance of security for blockchain technology. He also pointed out that the formulation of blockchain standards does not mean that it will rapidly promote the development of the industry, but rather gives certain guidance to the industry. Previously, China had suffered a lot in terms of international intellectual property rights and standards. In terms of blockchain, China has now formed more than 200 patents in international blockchain, and has even stood at the forefront of the world's technology. Therefore, we also need to firmly grasp our right to speak.

Blockchain technology has been regarded as the core technology with the greatest potential to trigger the fifth round of disruptive revolution after steam engines, electricity, information and Internet technology. In the past 10 years, with the strong support of the government and policies, the development situation of my country's philanthropy has been relatively optimistic. However, as the scale of charity continues to develop and expand, my country's public welfare undertakings have gradually revealed some shortcomings. The biggest problems existing in traditional public welfare undertakings are insufficient credibility, imperfect internal management of charitable organizations, and high costs. However, many Internet public welfare service companies are currently actively using the new technology of blockchain to solve this problem. Blockchain technology has the characteristics of decentralization, information traceability and non-tampering, openness and transparency, and smart contracts. It can make up for the shortcomings of traditional public welfare undertakings such as opaque information and low management efficiency. Blockchain technology will enter public welfare undertakings and will Bring new development opportunities to the charity industry.

Purpose of the research:

As the scale of my country’s public welfare continues to develop and expand, our shortcomings have also been exposed, including lack of credibility, and charitable organizations There is a lack of management, and the use of blockchain technology can solve this problem. This technology will track and store data and behaviors throughout the donation process, realize the complete disclosure of the public welfare chain, enable donors to effectively supervise, avoid shortcomings such as low efficiency and clear fund flows, control risks for public welfare projects, and improve Credibility and transparency of public welfare projects promote the development and progress of public welfare projects and enhance trust between people. According to the attributes and characteristics of the blockchain system, public welfare enterprises can implement full-cycle tracking, evidence storage and auditing of data and behaviors in the public welfare process, so that all parties involved in public welfare projects can conduct full-process tracking and effective supervision of the project, avoiding Due to the shortcomings of artificially reducing efficiency in public welfare, it provides a rational method for public welfare projects to control risks and judge effects, improve the transparency of public welfare undertakings, and promote the development of public welfare.

Significance of the project research: This project intends to develop an open and transparent system for tracking public welfare donations based on blockchain technology and combined with the actual development of public welfare undertakings in my country. Through an in-depth analysis of blockchain technology and the business of philanthropy, we discovered that blockchain technologyIt has a natural advantage in solving the problem of public welfare transparency. Blockchain technology can be understood as a distributed accounting method that can record all transaction information and ensure that it cannot be tampered with. This determines that wherever justice, fairness, and integrity are required, blockchain has great technology. Room to play. At the same time, the addition of smart contracts directly solves the business problem of earmarked funds.
