Ⅰ Where to view your own Huanhe digital collection

Tencent Huanhe app is online. PANews reported on January 7 that the "Dunhuang Cultural Creativity-Millennium Colorful Digital Mural" reservation page was launched in the Tencent Magic Core app. This digital collection is the first digital collection project jointly developed by Tencent Magic Core and Tencent Blockchain.
Huanhe said that Huanhe will fully open up its digital collection development and digital collection exhibition capabilities, and join hands with more and more partners to explore the digital economic ecology. Supports multi-chain engine architecture to meet the on-chain transaction needs of different IP scenarios through the assembly line.
It is understood that the Tencent blockchain brand is affiliated with Tencent Financial Technology (FiT). Since 2015, the Tencent blockchain team has built a domestically produced, independently controllable blockchain service infrastructure from scratch. Tencent Blockchain has achieved many achievements in technology exploration and application implementation. It leads the country in the number of technology patents and has been applied in multiple scenarios such as smart taxation, supply chain finance, games, medical care, public welfare, and carbon neutrality. .

II How Tencent responds to blockchain issues

Although Bitcoin has always had mixed reputations, the underlying technology blockchain that supports its development has been increasingly recognized and valued by all walks of life. At the beginning of 2018, the popularity of blockchain has rapidly escalated again. Not only small start-ups, but also giant companies such as Tencent, Alibaba, Internet, and JD.com have also increased their investment in blockchain.

Tencent’s blockchain applications are in the stage of gradually blooming in many areas. Blockchain technology has been applied in supply chain finance, Tencent Micro Gold, logistics information, and legal evidence storage. , public welfare recruitment and other fields. In addition, Tencent also launched the blockchain open platform BaaS.

Cai Yige also revealed that this year he will promote the combination of blockchain and supply chain finance and launch an open platform for supply chain finance. At the same time, we continue to explore and implement in areas such as ABS platforms and virtual digital assets.

Ⅲ How is the development of Tencent Blockchain? What are the scenarios where blockchain concept stocks have been implemented? Is it a new outlet for getting rich?

In the field of blockchain, Tencent Blockchain development The speed is relatively fast. As early as 2015, the Tencent blockchain team has begun to pay attention to blockchain technology and conducted independent research and development. As of December 31, 2019, the number of Chinese invention patent applications related to Tencent blockchain reached 990, and in China Ranked first among applying companies. After several years of R&D and exploration, Tencent Blockchain has achieved good results in both the development of underlying technology and the construction of industrial ecology.

The development history of Tencent’s blockchain:

There are no technical problems, it’s just a question of whether to do it or not. ”

When asked what technical difficulties he encountered, Cai Yige, the head of Tencent Blockchain, answered this way. After thinking about it, he added that for theories such as secure multi-party computation and zero-knowledge proof, The technology that has made breakthroughs in the industry has not yet been engineered. This is a problem for the entire industry.industry issues.

For Tencent Blockchain, the bigger problem seems to be finding more scenarios. "Blockchain + supply chain finance" is a scenario that Tencent is promoting this year.

At the end of last year, the supply chain financial service platform Xingbei Cloud Chain was released, and its underlying blockchain technology is supported by Tencent Blockchain. In addition, Tencent also invested in Lianyirong, which was Tencent’s only strategic investment in supply chain finance.

Now, almost a year has passed, how is the progress of this scene and Tencent Blockchain?

Today, after the establishment meeting of the Blockchain Policy and Legal Research Group and the launch of the "Blockchain and Supply Chain Finance White Paper", Odaily Planet Daily interviewed Cai Yige, General Manager of Tencent's Blockchain Business and Lian Ji Kun, General Manager of Yirong Company.

According to two sources, in less than a year of operation, the micro-enterprise chain platform has approximately tens of billions of transactions on the chain, with 12 banks connected and more than 70 companies participating, involving Energy, automotive, manufacturing and other industries. The current penetration supplier level is about level 1 and level 2, which can lower the interest rate by 2-8 points compared with traditional bank loans.

The micro enterprise chain platform is Tencent’s key case in supply chain finance. Tencent mainly provides the underlying technical infrastructure, including the underlying self-developed alliance chain, real-time clearing and account transfer capabilities; Lianyirong is mainly responsible for integrating resources and promoting the platform.

Supply chain finance is the leading scenario of blockchain, but its actual implementation is still very slow, which makes people doubt the substantial changes it brings. The two do not deny that this business is in a very early stage, and it will take some time to promote companies to join, but they both believe that "after joining the blockchain, supply chain finance will actually change a lot."

What Odaily Planet Daily wants to know more is, with the addition of supply chain finance after blockchain, will companies and financial institutions be more willing to join? And can this reduce the balance of small and medium-sized enterprise loans and increase the number of enterprises that receive loans?

“The biggest difficulty (in supply chain finance) lies in the participation of financial institutions, because they can only provide funds.” Ji Kun believes that the addition of blockchain can enhance banks’ willingness to enter supply chain finance.

In his opinion, the traditional banks of the four major banks are quite keen on the layout of blockchain. He said that supply chain finance itself is decentralized and the authenticity of underlying assets is very difficult to check. It is not mainstream in traditional financial institutions, and there was no way to achieve penetration before, so banks can only obtain the data of first-tier suppliers. But those in greatest need of financing may be second- and third-tier suppliers. Now blockchain + supply chain finance has changed the credibility of multi-level data circulation, strong credit cannot be split, and the synchronization efficiency of information, making it difficult for small, medium and micro enterprises in the supply chain to obtain loans from financial institutions in the past. Can get a loan. Banks have always wanted to do business with second- and third-tier suppliers. By joining the blockchain, institutions can better control their own data.

As for promoting enterprise use, Ji Kun said that it will take a certain amount of time for many enterprises to accept it.However, because the blockchain of supply chain finance mainly replaces the original role of commercial bills, the circulation of commercial bills itself has some pain points, such as counterfeiting, so they are relatively easy to accept.

When Odaily Planet Daily asked about how to ensure the authenticity of on-chain information, Cai Yige said that different information can be cross-verified, but he also believed that this was indeed a problem, using blocks The chain does not guarantee the authenticity of the information on the chain. Therefore, the first step of the micro enterprise chain's assets is actually accounts receivable, and it is true to use invoices to protect the underlying assets. As the business systems of small and medium-sized enterprises become electronic, they will go deeper in the future.

He also added that blockchain can also improve the efficiency of information synchronization. "I think it is the control of information. It turns out that in a centralized situation, even if you have information, it can be tampered with."

After talking about the focus of Tencent Blockchain this year, everyone naturally wants to know the future plan of. However, Cai Yige’s answer was the same as at the beginning: “We can’t talk about plans. We will continue to think about the scenarios in which blockchain can exert value.”

About this development:

First, you must choose the right scene and be sure to find experts in this industry.

Second, it must be in line with the nature of technology and have commercial value.

Third, it must meet the needs of future development.

Fourth, the architecture must truly solve the problem and be fully integrated with other technologies.

The concept of blockchain should be a new trend. Specifically, make more use of Internet searches to increase knowledge. Internet search results-Tencent Blockchain Development will be put for you.

Ⅳ In addition to WeChat Pay, what financial technology products are better from Tencent?

Hello, such as Wealth Management, just like Ant Fortune in Alipay, you can easily purchase funds. Financial product.

IV What Tencent has done in the blockchain

Ma Huateng: Blockchain, OK; ICO, not OK

At the two sessions, Ma Huateng said blockchain The topic has been very hot recently, and some people even ridiculed that the Internet before blockchain was the "classical Internet." Although blockchain technology is innovative, how to make good use of this technology is another issue.

In Ma Huateng’s view, blockchain technology can be applied in many fields, especially in digitally authenticating the uniqueness of physical objects. Just like a document, a ticket, etc. in reality, blockchain technology can be used to ensure that they cannot be copied or tampered with. Compared with traditional IT technologies in the past, blockchain is of epoch-making significance in truly simulating the uniqueness of documents and receipts in real society.

As for doing digital currency ICO, Ma Huateng believes that there are still many risks. He said: "If everyone can use blockchain technology to issue digital currencies at will, it will cause a lot of regulatory issues."

For example, gold was tested during the Spring Festival in 2017 The red envelope project is Tencent’s attempt to use blockchain technology to record users’ digital assets. returnIn terms of public welfare tracing, Tencent also uses blockchain technology to reduce the problem of information asymmetry.

In addition to finance and public welfare, Tencent also reached a cooperation with Intel in September 2017, announcing that the two parties would jointly develop blockchain technology to improve security protection capabilities in Internet of Things scenarios.

VI When was Tencent’s blockchain team established?

A vigorous “blockchain movement” swept across like a wave, enveloping everyone around us. people. The debate surrounding blockchain has never stopped from last year to this year. Is blockchain the "spring of mankind" and "the antidote to the global economic collapse" as its advocate Chen Weixing said, or is it as its skeptic Zhu Xiaohu What he said is that "blockchain is a fake trend, and there is nothing left except currency speculation."

We believe that this industry needs standards, otherwise everyone will talk about blockchain for a long time, and the concepts they talk about are different. Some companies even claim to do blockchain by themselves, but they just use Change the database. With the authoritative standard of trusted blockchain, companies that are obviously trying to sell their products can be screened out, and companies that truly engage in blockchain technology can get endorsements.

CE: Faced with the problem of scarcity of talents in the blockchain field, how does Tencent solve it?

Cai Yige: Our technical talents are basically converted from within Tencent. The blockchain industry is very new, and few people have done blockchain. Just like the arrival of mobile networks back then, it was very difficult for you to recruit developers for Android and IOS. We all trained ourselves.

Ⅶ FISCO - Golden Chain Alliance creates a new era of public alliance chain

Public chain, alliance chain (permission chain) and private chain can be said to basically include the blockchain technology Three ways to use. In recent years, the planning, financing, development and ecological construction of public chains can be said to have been carried out in a noisy manner. Some are real, and even more are deceived. It is noisy, noisy, muddy and sandy, and investors' money has really gone in. But not many are online, and the ecological construction of the few public chains that are online is also sparse. There are very few DApps, and the daily activity is even less. In short, not many current public chain projects can or are willing to survive. Ecological construction is even further away.

Private chains are self-built and internally operated blockchain structures of respective companies and institutions. Very little information is disclosed, but I believe that using your own money to do your own things and solve your own problems will not cause any problems. What a big deal.

The development of the alliance chain has always been low-key. Since blockchain technology was recognized by the mainstream economy and society, pragmatic mainstream economic institutions have been solidly carrying out research, development and application for about 4 years. During this period, the backbone of the alliance chain was formed, and another correct path was found for the implementation of blockchain applications and ecological construction. In a certain sense, the alliance chain has passed its infancy and has begun to solidly move towards the "public alliance chain" new era. The alliance chain is naturally connected with mainstream economic industry resources.The strong relationship with the source also determines the mainstream status of the alliance chain in the application prospects of blockchain technology.

With the dawn of the digital economy era and the popularization of distributed business models, blockchain technology has also been able to give full play to its advantages and become a representative of cutting-edge technology. In 2016, three companies, WeBank, a member of the Golden Link Alliance, Shanghai Wanxiang Blockchain, and Matrix Yuan, a member of Chinaledger, reached a strategic cooperation and jointly committed to exploring blockchain technology, and

The full name of Golden Link Alliance is Financial Blockchain Cooperation Alliance (Shenzhen). It was jointly established on May 31, 2016 by more than 20 financial institutions and technology companies including Shenzhen Financial Technology Association, Shenzhen Qianhai WeBank, and Shenzhen Securities Co., Ltd. Non-profit organization established. As an open organization, Financial Institutions that voluntarily abide by the charter and companies that provide technological services to financial institutions can apply to join. So far, members of the Golden Link Alliance include more than 80 institutions in six major industries including banks, funds, securities, insurance, local equity exchanges, and technology companies.

On November 26, 2016, Golden Link Alliance released the "Financial Distributed Ledger Proposal", proposing five major principles such as legal compliance, traceability, security, privacy protection, and business orientation, as well as a value alliance , autonomous and controllable, safe and trustworthy, efficient and available, business feasible, flexible configuration, intelligent supervision and other seven propositions.

Purpose: Integrate and coordinate financial blockchain technology research resources, form a synergy and coordination mechanism for financial blockchain technology research and application research, and improve the research and development capabilities of member units in the field of blockchain technology. Explore, develop, and implement financial alliance blockchain suitable for financial institutions, as well as application scenarios based on this.

The General Assembly of the Golden Chain Alliance is the highest authority; the permanent body of the General Assembly is the Presidium, which leads the alliance to carry out daily work during the intersessions of the General Assembly and is responsible to the General Assembly; the Presidium has a technical committee (chaired by Application project work), Standards Technical Working Committee (presides over the establishment, formulation, review and release of standards), Advisory Committee (organizes external experts to participate in technical and standards discussions).

Jinlianmeng has established research directions in the fields of credit, equity, points, insurance, bills, cloud services, digital assets, financial product issuance and trading, and some of the projects have now been implemented or products have been launched. prototype.

The FISCO BCOS underlying blockchain platform is jointly built by the FISCO open source working group. Members of the working group include Beyondsoft, Huawei, Shenzhen Stock Exchange, Digital China, Sifang Inextron, Tencent, WeBank and Yuexiu Jinke and other members of the Golden Link Alliance, aiming to create a secure and controllable blockchain suitable for the financial field. Chain bottomplatform.

Financial services are one of the earliest application areas of blockchain. Blockchain technology brings advantages such as safety and reliability, simplified processes, cost savings, reduced operational risks, and increased trust, and has the potential to reconstruct and sublimate the original financial industry infrastructure. The financial industry focuses on multi-party reciprocal cooperation and has strong supervision and high-level security requirements, which require node access and authority management. Therefore, the technical direction of the alliance chain has become the main choice for the financial industry.

At present, my country's financial industry is opening up to the outside world with unprecedented intensity, and the pace of financial innovation is also accelerating. Therefore, how to effectively balance the relationship between open innovation and risk prevention and firmly maintain the bottom line of no systemic risks is an important issue for the industry. challenges that urgently need to be addressed.

From the perspective of financial IT infrastructure, there are still some shortcomings and pain points in operational risks, moral hazards, credit risks, information protection risks, etc.

First, financial IT system data may still be tampered with, forged, or have consistency differences.

Second, the infrastructure structures and business processes of different financial institutions are different, and even still involve many manual processes, which greatly increases operating costs and is also prone to operational risks and ethics. risk.

Third, financial business and financial cooperation may involve multiple participants or intermediaries, which can easily increase trust costs and friction costs. There are also certain issues of mutual trust, collaboration or cooperation reciprocity.

Fourth, financial business is often highly complex, and it is easy to miss records of all business elements. Sometimes it is difficult to trace the entire business process, and it cannot meet the needs of supervision and auditing.

Fifth, the data between different financial institutions are relatively independent, making it difficult to achieve safe and efficient interaction, resulting in high costs for repeated KYC, anti-money laundering, and anti-fraud, and also indirectly causing the loss of user data. Risk of disclosure by certain intermediaries.

Sixth, the availability and adaptability of centralized IT infrastructure are weak, and distributed technologies need to be used to improve robustness or adaptability.

As a combined infrastructure solution, blockchain technology can in principle respond to the needs of the financial industry. However, because the requirements of the financial industry are more diverse and strict, as a financial version of the blockchain solution, it needs to be based on the blockchain technology of the universal industry and according to the special business needs of financial institutions, existing technical levels, and laws and regulations. Requirements or conditions in other aspects shall be comprehensively considered from multiple dimensions such as business suitability, performance, security, policy, technical feasibility, operation and maintenance and governance, and cost.

First, the appropriateness of the business scenario. Not all financial business scenarios require the use of blockchain technology. Generally speaking, those involving multi-party participation and peer-to-peer cooperationIn this scenario, the traditional centralized system architecture is often difficult to meet the needs, so you can consider using blockchain technology to increase mutual trust among multiple parties, improve business operation efficiency, and reduce business operation costs and friction costs.

Second, the performance of the blockchain system. Financial business often has characteristics such as massive transactions, high-frequency transactions, and timely confirmation. Therefore, the blockchain open source platform in the financial industry needs to analyze the business volume, potential business growth scale, and potential business growth scale that the blockchain system needs to support based on the current business scale of financial institutions. Technical performance index requirements such as concurrent business volume and response time. Since blockchain platforms using different technical modules, such as different consensus mechanisms, have greatly different performance support, it needs to be evaluated based on business performance requirements and combined with blockchain performance efficiency indicators.

Third, the security of the blockchain system. Blockchain can ensure the credibility of recorded data from a technical level and prevent data from being tampered with, forged and other risks. In addition, in terms of data sensitivity and security, it is necessary to evaluate the content encryption strength of the on-chain data, as well as access control, etc. Financial institutions need to choose mature, appropriate, and secure encryption algorithms based on the specific security requirements of their business.

Fourth, policy compliance. Blockchain is a set of technical solutions that, with reasonable design, can provide good support for existing businesses or complement existing centralized systems. However, when financial institutions use blockchain to conduct business, they must implement it within the country's existing regulatory requirements and legal framework.

Fifth, technical feasibility. Blockchain technology has already been implemented in some financial scenarios, but it is still an emerging technology. It is necessary to fully evaluate the fit of the technology with specific businesses and its advantages and disadvantages compared with traditional systems before finally choosing the appropriate area. Demonstration and trial operation of the blockchain platform.

Sixth, operation and maintenance and governance capabilities. Since there are differences in operations and management between blockchain-based businesses and traditional centralized systems, and the continuous governance requirements of financial businesses are extremely high, corresponding planning and adjustments are required to evaluate the feasibility and sustainability of the new governance structure. , evaluate the impact of version iterations and the official launch of the system, monitor the operation of the blockchain system in real time, and ensure business controllability and financial environment stability.

Seventh, costs are controllable and economically feasible. Blockchain applications use technical features to solve specific problems in actual business. Applications that effectively solve pain point problems can bring great benefits to financial businesses, and the value of the application itself can also be revealed; on the contrary, if it cannot solve important problems in the industry , you need to face a trade-off between costs and benefits.

If a safe and reliable underlying financial blockchain platform can be built to meet the special needs of the financial industry, blockchain technology will be of great use in the financial industry.

For example, from the perspective of banking institutions, the focus is on exploring waysThe general trend is to apply blockchain technology to reduce clearing and settlement costs, improve middle and back-end operational efficiency, improve process automation, and reduce operating costs. In addition, in cross-border financial scenarios, blockchain can help realize ledger sharing among cross-border financial institutions, reduce reconciliation and settlement costs and dispute friction costs between cooperative banks, thereby improving the processing speed of cross-border business. and efficiency.

From the perspective of non-bank financial institutions, blockchain can be used to improve the authority of rights registration and information storage, reduce counterparty risks, solve data tracking and information anti-counterfeiting issues, and reduce audits. operating costs, etc.

From the perspective of financial regulators, blockchain provides regulators with consistent and easy-to-audit data. Through data analysis of inter-institutional blockchains, the audit process can be faster and more efficient than traditional audit processes. Precisely regulate financial operations. For example, in an anti-money laundering scenario, the balance and transaction records of each account are traceable, and no aspect of any transaction will be out of sight of supervision, which will greatly strengthen anti-money laundering efforts.

Designed an efficient, reliable, message communication protocol based on the blockchain network, referred to as AMOP (Advanced Messenger On-chain Protocol), focusing on the following functions:

 Based on the blockchain network, it supports cross-bank and point-to-point real-time message communication;

 Provides standardized interfaces for the interaction between off-chain systems and blockchain;
< br />  The blockchain system can actively call the business interface of the off-chain system;

The technical characteristics of this protocol are:

 In the point-to-point blockchain network topology , plan node communication paths to ensure message reachability;

 Can quickly sense node abnormalities in the blockchain network and automatically switch paths to resend messages;

 In communication Encryption technology is used in the process to ensure privacy at the communication layer.

Designed the contract naming service CNS (Contract Name Service). The design goal of CNS is to name the correspondence between the business layer and smart contracts, so that the business layer no longer cares about the relevant contract addresses. Similar to DNS on the Internet, the use of domain names makes it easier for users to remember how to access a website, and also gives the website great flexibility in terms of clustering, migration and expansion.

Special Prize: ODRchain - a typical application of public consortium chain

The most high-profile champion project - ODRChain, is based on the FISCO BCOS underlying platform and uses blockchain technology to solve the pain points of traditional judicial processing of online disputes, such as the difficulty in verifying the authenticity of electronic data and the inability to digest a large and rapidly backlog of case disputes.

At present, ODRChain has shortened the time it takes for customers to go from clicking "one-click arbitration" to receiving the arbitration award, from the traditional arbitration process that lasted several months to about 7 days. , and the arbitration fees that originally cost tens of thousands of dollars have been reduced to a few hundred yuan. As of December 2018, ODRChain has completed the deposit of over 10 million contracts, involving hundreds of billions of funds.

First prize: JustSign - a white-box cryptographic algorithm that turns a mobile phone into a USB shield

The project that grabs the first prize in the competition - JustSign, is based on FISCO BOCS It is an electronic contract signing and certificate storage system. Its original JustKey white-box cryptographic algorithm realizes "mobile phone as USB shield", which solves the problem of limited compatibility of traditional CA, inability to protect key security on the mobile terminal, and vulnerability to attacks in centralized data storage. question.

Expert reviewers commented that electronic contracts involve complex legal relationships and ownership of interests, and it has long been difficult to achieve a balance between security, integrity and portability. The team’s original white-box cryptographic algorithm is really conducive to improving security in blockchain certificate storage scenarios.

Second Prize: Internet of Things Trusted Interconnection Solution - The Smart Life Picture Looks Like This

The Internet of Things Trusted Interconnection Solution entered by Sichuan Changhong Security Laboratory depicts an almost useless You should pay more attention to the smart home blueprint. When analyzing the blockchain technology behind it, a team representative said that an inter-enterprise cooperation alliance is established based on the alliance chain to open up the interconnection and mutual trust of IoT devices between different manufacturers, and based on insights into typical business scenarios of smart life, through smart contracts Implement smart terminal registration, scene rules, trust rules and linkage rules.

Expert judges of the competition believe that this project has practical hardware and scenarios in the field of Internet of Things, and is expected to further promote the implementation of application scenarios such as distributed AI assistants, resource sharing, life cycle management, and multi-channel payment. Truly usher in smart life.

Among the projects that won the third prize in the competition, they accurately targeted the characteristics of blockchain in terms of security and efficiency improvement, and provided practical solutions for the industries they represented. Tsinghua University The team of teachers and students found a new way to develop cross-layer full-stack blockchain security detection technology to protect other blockchain applications comprehensively, and its technical strength was highly praised by the judges.

The third prize winners were the trusted electronic certificate platform of Shenzhen E-Commerce Security Certificate Management Co., Ltd., the real estate registration platform of Wuhan Liandong Times Technology Co., Ltd., and Shandong Guanhai Data Technology Co., Ltd. The company's Rongcheng blockchain service platform, the livestock industry blockchain traceability of Quanliantong Co., Ltd., the tourism finance alliance platform of Shenzhen Youxun Information Technology Co., Ltd., and the copyright safe deposit box of Beijing FamilyMart Technology Development Co., Ltd.

Shanghai Jiuyaojiu Information Technology Co., Ltd.’s first-responder mutual aid first aid, “Yongteng Group My Innovate”’s HaveFund, Qianhai Life Insurance Co., Ltd.’s blockchain policy management, “Huazhong Technology The university's Guanshankou Hulu Brothers' Book Campus and the Cloud Block project team's "Yun Block" account system also won the competition's Outstanding Social Value Award, Outstanding Business Design Award, Outstanding User Value Award, Outstanding Creativity Award, and Outstanding Application Integration Award respectively.

Ma Zhitao, chairman of the Golden Alliance Technical Committee, elaborated on the concept of the “Public Alliance Chain”. He believes that the alliance chain should achieve self-sublimation and should be able to evolve into an ecosystem that provides services to the public, that is, a "public alliance chain."

Different from the public chain project’s idea of ​​“coming up with a plan first, raising funds, vigorously promoting it, raising the price, and finally investing in development”, the alliance chain project adheres to the idea of ​​“investing in development first with its own funds” , verify in the production environment, accumulate real customers and users, run steady trials and errors, and finally carry out promotion and publicity.” However, due to the focus on practical implementation and focusing on real applications, there is a lack of publicity.Without it, we have no choice but to fall into the passive situation of "there are many people who have implemented it, but few people who are applauding it". Golden Chain Alliance hopes that through this competition, the project team of the alliance chain will come to the stage to show their results, enhance the influence of the alliance chain, and let the public know more about the real application implementation and sustainable development of the alliance chain project.

Ⅷ How does the third-party electronic contract platform ensure data security when signing electronic contracts online?

Take the electronic contract signing platform for pen boxes as an example:

① Real-name authentication: Before signing the contract, the user needs to conduct real-name identity authentication on the Pen Box electronic contract platform. After passing the authentication, the platform will work with the CA agency to issue a CA certificate to you

②Transmission encryption: guaranteed by digital signature technology mechanism Electronic signatures ensure that data and documents are not tampered with or lost during electronic contract transmission.

③Third-party time acquisition: The signing pen box has an IP certificate storage function during the electronic contract signing process, a unique time source evidence chain, and a trusted timestamp that effectively prevents the contract from being signed by different people in different places and prevents Illegal tampering with the contract.

④PDF anti-tampering: The electronic contract of the Pen Box electronic contract platform uses PDF file encryption format, which plays a certain role in anti-tampering.

⑤Cloud storage: Regarding the storage of contracts, in fact, electronic contracts are stored locally, and the evidence efficiency is low, because it is difficult for you to prove your innocence; and when it is stored at a network service provider, evidence collection will also be very troublesome; Therefore, a third-party electronic contract platform should be the best choice: Pen Box Electronic Contract encrypts and stores the signed contract in a secure cloud storage, ensuring the original output of the contract, simple evidence collection, and high legal effect.
