⑵ New possibilities! Blockchain technology empowers the cultural industry

On June 11, 2021, the first Blockchain + Cultural Industry Forum and Blockchain Assisted the Digital Transformation of the Cultural Industry Seminar was held in Beijing. Currently, blockchain technology is developing rapidly and is gradually extending from finance, Internet of Things and other fields to the cultural field. The blockchain + cultural industry shows broad development prospects.

What is blockchain?

Blockchain is essentially a distributed encrypted database that integrates distributed network, smart contracts, asymmetric encryption and other technologies. Based on cryptography, blockchain encrypts data with timestamps to form a data chain and stores it in a distributed form. Blockchain technology has the characteristics of decentralization, difficulty in tampering, traceability, openness and transparency.

How does blockchain empower the cultural industry?

Blockchain’s empowerment of cultural industries is mainly reflected in three aspects: digital copyright protection, reshaping cultural industry models and cultural product innovation.

1. Digital copyright protection

2. Reshaping of cultural business formats

With the characteristics of decentralization, blockchain can break the centralized business of the previous cultural industry. model to reduce the cost of the entire process from cultural production to consumption. Blockchain can establish a point-to-point direct connection between content producers and consumers, allowing copyright owners to obtain direct and immediate benefits and stimulating the creative enthusiasm of content producers. At the same time, the blockchain can also empower the cultural and tourism industry, by recording tourism information on the block, realizing resource integration and promoting the development of global tourism. In addition, blockchain technology can also play a positive role in the value appraisal of intangible cultural heritage and some artworks, and the construction of industrial chains, increasing their market value.

3. Cultural product innovation

Blockchain can create native blockchain products in the cultural field, such as NFT (Non-Fungible Token). NFT is a non-fungible token based on blockchain encryption technology. It is the only encrypted token used to represent digital assets. As a digital carrier of cultural products, NFT can ensure the non-replicability and uniqueness of cultural works, ensuring the market value of NFT. Whether it is paintings, music, games or novels, their digital content can be tokenized, and the tokenized products can be traded at any time, greatly increasing the liquidity and industrial value of cultural products.

The development prospects of blockchain + cultural industry

I believe that with the evolution and development of blockchain technology, blockchain technology will have a deeper integration with the cultural industry and continue to Generate new cultural business formats and promote the digital transformation and upgrading of the cultural industry.

⑷ Technology exploration is in progress: Blockchain is testing the waters for Internet financial dispute resolution

Financial digitization is replacing the traditional credit model. However, while automated credit approval brings efficiency and convenience to financial institutions, the rapidly growing number of credit transactions also puts pressure on back-end overdue dispute processing.

The collection results carried out by financial institutions on their own are not good, and it is difficult to manage the standard collection when cooperating with third-party collection agencies. This leads to the frequent occurrence of violent collections, which is always hanging over the heads of the institutions. problem to solve. Blockchain technology is trying to provide solutions to the "stubborn problems" of this industry.

Smart contracts transform the entire business process

"Small amounts and decentralization" are important goals for the in-depth development of inclusive finance. However, the traditional collection model is obviously ineffective in terms of cost and operational difficulty. It cannot match the current needs of Internet finance.

In the past ten years, personal consumer credit has developed rapidly. Data from the China Banking and Insurance Regulatory Commission from 2015 to 2021 show that consumer loans have accounted for more than 20% of the total balance of RMB loans for a long time, and this proportion has shown an overall growth trend. According to the "Data on Main Regulatory Indicators of the Banking and Insurance Industry in the Fourth Quarter of 2021", in the fourth quarter of 2021At the end of the quarter, the balance of non-performing loans of commercial banks was 2.8 trillion yuan, an increase of 13.5 billion yuan from the end of the previous quarter.

Taking the practice of communication and negotiation between attorneys and borrowers as an example, under normal circumstances, overdue borrowers with low willingness to repay have weak legal awareness, and it is not uncommon to use property transfer and other means to evade debt. Therefore, Ordinary phone calls and text messages to collect collection do not have much effect. However, after accessing the court's judicial blockchain system, parties can log in to the court website to check the loan evidence on the blockchain, which will put pressure on credit penalties for this type of borrowers, both in terms of efficiency and endorsement capabilities. . More importantly, before an overdue transaction occurs, the blockchain evidence can not be tampered with, which can have the effect of urging the entities on the chain to keep their promises in good faith.

A case disclosed by the official WeChat account of the Supreme People’s Court shows that a natural person, Yang, signed a personal agreement with Hangyin Consumer Finance Co., Ltd. (hereinafter referred to as “Hangyin Consumer Finance”) on the “Hangyin Finance” App. Loan Contract. Yang failed to repay the loan on time, and Hangyin Xiaojin filed a lawsuit with the court after repeated reminders. As an access party to the judicial blockchain of the Hangzhou Internet Court, the contract signed by Hangzhou Bank Consumer Finance and Yang has already been synchronized to the judicial blockchain. The objective facts were clear, and the advising judge conducted asynchronous mediation. Yang agreed to repay the money after being unable to deny it, and the case was settled within 7 days.

According to the Supreme People’s Court, in September 2018, the Hangzhou Internet Court officially launched the country’s first judicial blockchain platform. As of April 2022, the total amount of on-chain data exceeds 5.69 billion, more than 9,700 pieces of electronic evidence have been retrieved, and the dismissal rate of relevant cases exceeds 98.7%.

According to MaMa Consumer Finance, the company has currently based on its own blockchain technology, the electronic lawyer's letter automatically generated by the mediation platform and the mediation letter materials confirmed in real time by the customer's online mediation are stored on the chain. “The credibility of blockchain evidence solves the problems of difficulty in obtaining, storing, and authenticating evidence during judicial proceedings, supports enterprises to efficiently collect non-performing assets, and can especially improve notarization, mediation, and even execution of small batches. The efficiency of evidence storage, processing and trial in the investigation and control process."

Cross-chain interoperability needs to be further implemented

The person in charge introduced that the current model adopted by the company is to cooperate with industry and information technology Cooperate with electronic certification service agencies established with permission from the Ministry of Finance to provide full-process electronic certificate deposit services for consumer finance companies’ loan businesses. When filing a case, an electronic certificate deposit report is provided to prove that the entire process data is true and has not been tampered with. "This is also a common model at present. Its advantage is that it has wide adaptability and can carry out litigation or arbitration services in multiple courts or arbitration committees that meet the jurisdiction requirements. The disadvantage is that it requires initial communication with the courts and arbitration committees to confirm the electronic existence It takes time to review the electronic evidence report corresponding to each case when filing a specific case."

At the same time, the above-mentioned persons in charge did not hide their expectations for emerging technologies: for judicial blockchain , consumer financeThe business is combined with the judicial blockchain led by the court. When an overdue repayment dispute is submitted to the court for filing, the consumer finance company can directly authorize the court to go to the chain to obtain information on the entire business process, effectively simplifying the evidence submission process and ensuring the authenticity of the evidence. Improve the effectiveness of the evidence chain and the efficiency of review of evidence materials to achieve rapid case filing and efficient trial. “Realizing data submission and docking through this technology is expected to further enhance the effective protection of personal information.”

Each DApp runs on its own blockchain, and its data is public and forkable, just like Ethereum and blockchain.
Expansion information:
1.2017Zhu Xuejiao, who is well-known in the currency circle for her Kcash wallet project, has repeatedly expressed her optimism about the token economy. He even "tokenized" his abilities, issued "blessing coins" named after his surname, and conducted token experiments. Zhu Xuejiao’s KCASH currency has so far exceeded its crowdfunding price by 96%, and was almost delisted due to insufficient liquidity. Nowadays, KCASH's attention in the market has weakened, and Zhu Xuejiao has pushed two new currencies closely related to him to the secondary market. Some investors believe that neither KCASH nor Luwang’s dual currency have substantial applications and there is a risk of zeroing out. "Perhaps issuing coins one after another is his great experiment, but the consequences of failure will be borne by users who invest real money."
