Chongqing Jinwowo Analysis: The ultimate goal of blockchain technology is to provide real-world business solution.
By allowing blockchains to connect independent sidechains, enterprises will find that they can create customizable solutions to meet business needs.

2. What does my country’s blockchain team building solution include?

my country’s blockchain team building solution includes:

1. Team building must break the tradition It is bound by disciplines and colleges and gives full play to the advantages of cross-disciplinary research.

2. Establish a chief expert responsibility system.

3. Strictly manage the size of the team and encourage in-depth communication among members.

4. Strengthen the joint construction of blockchain scientific research teams to achieve complementary advantages and strong alliances between teams.

Origin

Blockchain originated from Bitcoin. On November 1, 2008, a person claiming to be Satoshi Nakamoto published The article "Bitcoin: A Peer-to-Peer Electronic Cash System" [4] elaborates on the architectural concept of an electronic cash system based on P2P network technology, encryption technology, timestamp technology, blockchain technology, etc., which marks the The birth of.

Two months later, the theory came into practice, and on January 3, 2009, the first genesis block with serial number 0 was born. A few days later, block number 1 appeared on January 9, 2009, and was connected to the genesis block number 0 to form a chain, marking the birth of the blockchain.

In recent years, the world's attitude towards Bitcoin has been ups and downs, but blockchain technology, one of the underlying technologies of Bitcoin, has received increasing attention. In the formation process of Bitcoin, blocks are storage units one by one, recording all communication information of each block node within a certain period of time.

The links between each block are realized through random hashing (also called hash algorithm). The latter block contains the hash value of the previous block. With the expansion of information exchange, a block Continuing with one block, the result is called a blockchain.

3. What kind of problems can blockchain technology solve

Blockchain technology can solve the trust problem at a relatively lower cost, which is very important for the current emphasis on reducing the burden of the real economy. , which plays an important role in reducing transaction costs and has great social value. At the same time, there is still a need for continuous exploration of the blockchain technology itself. It is believed that independent controllable intellectual property rights and patents can be integrated with this technology in the future.
In the future, Jinwowo will focus on promoting the legal circulation and commercial application of big data using blockchain technology.

4. What does blockchain + Metaverse solve?

Blockchain technology can provide a solution for value transfer in Metaverse. Blockchain technology has evolved from a single decentralized ledger application to a value transmission layer in virtual time and space. It has now realized a virtualA model for world value transmission. Relying on the open source application ecosystem and innovative business models, blockchain applications have developed and prospered rapidly, setting off rapid iterations around the world. Crypto-assets have experienced significant price fluctuations in the past few years, and mainstream society has very different attitudes towards blockchain technology and tokens. However, in terms of innovation alone, smart contracts, automatic market maker mechanisms, cross-chains, and second-tier networks are emerging in endlessly. From Bitcoin to Ethereum, to the recently popular DeFi and NFT, blockchain technology has demonstrated its efficiency as a clearing and settlement platform across time and space.

From the perspective of the Metaverse, it urgently needs economic rules. The reason why Roblox changed Game to Experience is because there is no transparent economic system in the traditional centralized game rules. Krypton gold players get pleasure from torturing non-RMB players, and they are also reaped by the endless inflation in the game. The emergence of blockchain ensures that the circulation of virtual assets can exist in a decentralized and independent manner, and the rules are fair and transparent through open source code, while the emergence of smart contracts and DeFi maps real-world financial behavior to the digital world.

5. How blockchain can solve pain points and change social networks

Theoretically, it can subvert existing social networks, but in fact it still faces many technical and policy difficulties. For example, DECENT, a relatively popular blockchain content publishing platform in recent times, has crowdfunded nearly 5,881 Bitcoins in the currency circle, equivalent to approximately 28 million yuan. This is a decentralized content sharing platform that anyone can participate in without any restrictions, but it still faces the risk of policy supervision globally. Now I can only use one sentence to describe the blockchain: the ideal is plump, the reality is skinny.

6. What is the blockchain + supply chain financial solution?

Since the blockchain has started a craze in China, the entire industry has been constantly exploring various implementation scenarios. It can be said that the blockchain is so attractive that it has attracted countless entrepreneurs to compete. So what are the advantages of blockchain in supply chain finance? What are the pain points in the traditional model? What new business models can blockchain create to solve these problems? How should blockchain startups enter this field? ?
Moody's, a world-famous bond rating agency, has given 127 blockchain cases, ranging from points to transaction settlement, from document depository to supply chain management, from cross-border payment to supply chain finance, various applications There are many.
Among so many applications, the field of supply chain finance has attracted much attention and has been commercialized.Progress is rapid.
This is because first of all, the supply chain finance scenario has a market scale of trillions, and the ceiling is high enough. Secondly, this scenario naturally requires multi-party cooperation, but there is no traditional centralized organization to manage it, so it needs to use regional Blockchain is used to build trust. At the same time, technically this scenario does not require high concurrency, and current blockchain technology can satisfy it.
1. Supply chain finance is a trillion-level market
Supply Chain Finance: refers to treating the core enterprises in the supply chain and their related upstream and downstream enterprises as a whole, with the core Relying on enterprises and taking real trade as the premise, we use self-reimbursement trade financing to provide comprehensive financial products and services to upstream and downstream enterprises in the supply chain.
Based on different financing collaterals, financial institutions divide supply chain finance into accounts receivable, prepayment and inventory financing, among which the scale of accounts receivable is particularly huge.
Data from the National Bureau of Statistics show that at the end of 2016, the accounts receivable of my country's industrial enterprises above designated size reached 12.6 trillion yuan, a year-on-year increase of 10%, which resulted in huge financing needs for enterprises. Compared with the huge accounts receivable, my country's annual commercial factoring volume in 2015 was only about 200 billion yuan. It can be seen that there are still a large number of supply chain needs that have not been met, so there is huge room for development of the supply chain finance industry.
2. How blockchain can solve the pain points of supply chain finance
Pain point 1: Financing is difficult and costly for small and medium-sized enterprises in the supply chain
Since banks rely on the core enterprises’ ability to control goods and To adjust sales capabilities, for the sake of risk control, banks are only willing to provide factoring business to upstream suppliers (limited to first-tier suppliers) that have direct accounts payable obligations for core enterprises, or to provide factoring services to their downstream dealers (first-tier suppliers). ), providing down payment or inventory financing.
This has resulted in the needs of second- and third-tier suppliers/dealers with huge financing needs not being met, the business volume of supply chain finance being restricted, and small and medium-sized enterprises not being able to obtain timely financing. Leading to product quality problems will harm the entire supply chain system.
Blockchain solution:
We issue and run a digital ticket on the blockchain, which can be split and transferred at will under open and transparent conditions and witnessed by multiple parties.
This model is equivalent to making credit in the entire business system transmissible and traceable, providing financing opportunities for a large number of small and medium-sized enterprises that were originally unable to obtain financing, greatly improving the efficiency and flexibility of bill circulation, and reducing Cost of capital for SMEs.
According to statistics, in the past, traditional supply chain finance companies could only provide financing services to 15% of suppliers (small and medium-sized enterprises) in the supply chain. After adopting blockchain technology, 85% of suppliers can All can enjoy financing convenience.
Pain point 2: As the main financing tools of supply chain finance, commercial bills and bank bills are currently used in limited scenarios and are difficult to transfer.
The use of commercial bills is subject to the credibility of the company, and it is difficult to control the arrival time of discounted bank bills. At the same time, it is not easy to transfer these bonds.
Because in actual financial operations, banks are very concerned about the legal effects of the "transfer notice" of accounts receivable claims. If the core enterprise cannot sign back, the bank will not be willing to grant credit. It is understood that the bank is very cautious about the legal effects of signing the "transfer notice" of the creditor's rights, and even requires the legal representative of the core enterprise to go to the bank to sign in person. Obviously, this method is extremely difficult to operate.
Blockchain solution:
A consortium chain can be created between banks and core enterprises, which can be used by all member enterprises in the supply chain. By utilizing the multi-party signature and non-tampering characteristics of the blockchain, The transfer of creditor's rights has reached consensus among many parties, reducing the difficulty of the operation.
Of course, the system design must be able to achieve the effect of legal notification of bond transfer. At the same time, banks can also trace transactions at each node and outline a visible transaction flow chart.
Pain point 3: It is difficult for the supply chain finance platform/core enterprise system to prove its innocence, resulting in high risk control costs on the capital side
In the current supply chain finance business, banks or other capital sides are not only worried about the company's In addition to the ability and willingness to repay, they are also concerned about the authenticity of the transaction information itself, which is recorded by the ERP system of the core enterprise.
Although ERP tampering is difficult, it is not absolutely trustworthy. Banks are still worried that core enterprises and suppliers/distributors collude to modify information, so they need to invest manpower and material resources to verify the authenticity of transactions, which adds additional Risk control costs.
Blockchain solution:
As a "trust machine", blockchain has the characteristics of traceability, consensus and decentralization, and the data on the blockchain is timestamped, even if Even if the data of a certain node is modified, it cannot cover the sky with one hand. Therefore, the blockchain can provide an absolutely trustworthy environment, reduce the risk control cost on the capital side, and solve the bank's concerns about information tampering.
3. How should blockchain companies enter supply chain finance
In terms of market selection, we believe that blockchain startups should choose subdivisions with high ceilings, such as home appliances, automobiles, retail, and clothing. , pharmaceutical industry, etc. On the one hand, these industries have a vast market; on the other hand, their supply chain management infrastructure is relatively complete, and the upfront cost of adopting blockchain is relatively small.
We believe that there are two models for blockchain companies to enter supply chain finance.
The first is to directly cooperate with core enterprises/platforms to provide them with underlying blockchain solutions. After accumulating enough data, build an alliance chain to connect with funds to provide financial services. (Consortium Chain Model)
Given that the blockchain itself cannot solve the problem of risk control, enterprise-level risk control at this stage still needs to revolve around strong core enterprises. At the same time, obtaining the support of core enterprises can also effectively solve the problem of customer acquisition. problem, because a large core enterprise usually has thousands of suppliers of various types.Should be business.
At present, domestic blockchain companies start from core enterprises, including Bubi, Wanglu Technology, etc. Bubi has launched a consortium chain "Buno" specially built for supply chain finance, integrating banks and core enterprises. , factoring companies, etc. are all linked. Bunuo is based in Guangzhou and Shenzhen, radiates business in the southeast region, and digs deep into the field of supply chain finance. It has previously signed a strategic cooperation agreement with Yigang.com.
The second model starts by providing supply chain management services, such as traceability, tracking, visualization, etc., integrating information flow, logistics and capital flow, and providing financial services on this basis. (Private chain mode)
This mode is equivalent to building an application scenario using blockchain. Just like Alipay back then, if Jack Ma had just started Alipay, it would have been difficult to do it because there was no application scenario, so he first started Taobao to serve the real economy. With Taobao, Alipay emerged as a centralized trust scenario, and other applications were grafted onto Alipay to create Ant Financial.
At present, among domestic blockchain companies, those that adopt the supply chain service model include BITSE and Food Excellence.
For example, VeChain provides an anti-counterfeiting traceability method by implanting an NFC chip into each product, registering the product on the blockchain so that it has a digital identity, and then recording this through a jointly maintained account. All information of digital identity achieves verification effect. At present, Vechain products have connected with more than 10 industry benchmark customers, and millions of IDs are running on the chain.
4. Three steps to build a supply chain financial exchange
From the perspective of implementation path, the application of blockchain in the field of supply chain finance can be realized in three steps.
As a premise, we need to first create a blockchain + supply chain finance alliance. Participants in the alliance include supply chain finance platforms, core enterprises, professional financial intermediaries, funders, factoring institutions, etc.
Each participant needs to assume corresponding obligations. For example, the platform is responsible for providing supply chain information, customer information and other basic services similar to water and electricity. The core enterprise understands the industry status, has control over the enterprises in the supply chain, and is responsible. risk control.
Professional financial intermediaries can integrate and analyze platform information and provide customized supply chain financial products, such as personalized blockchain electronic bills. Funding parties include banks, Internet financial institutions, etc. who are responsible for connecting customers with corresponding risk preferences.
After the alliance chain is established, you can start the three-step strategy.
The first step is to put the data on the chain, put the data in the supply chain alliance on the chain, use the characteristics of the blockchain to make it tamper-proof, and provide data verification, traceability and other services.
The second step is to digitize assets, turning warehouse receipts, contracts, and blockchain bills that can represent financing needs into digital assets, which are unique, non-tamperable, and non-replicatable.
The third step, the trading of digital assets, the supply chain financial platform will be transformed into aThe financial asset exchange transforms non-standard corporate loan needs into standardized financial products, tokenizes them, connects investment and financing needs, and conducts value transactions.
Ultimately, blockchain technology will effectively enhance the liquidity of supply chain financial assets, mobilize new financing tools and risk control systems to help cover the long-tail market for small and medium-sized enterprise financing, and give birth to supply chain finance as a service.
