Describe the nature and duration of your affiliation with the Filecoin project. Please include relevant Github handles, miner ids, significant projects or contributions (with links).


In 2013, as a participant and builder of early Bitcoin mining, I deeply felt that the blockchain is different from the traditional industry and has great charm, so I started to contact and study the blockchain technology and related projects.

In 2017, during the booming trend of ICO, I reached IPFS/Filecoin project from the earliest promoting team in China. At that time in China, internet was in rapid development, data storage and privacy was a big problem of the entire Internet industry, which realized me that IPFS/Filecoin is an important way for future internet development, so I began to consult a large number of authoritative information research of the project.

In 2018, after my deep research and learning process lasting for more than a year, I contacted with authoritative experts from different fields such as government, universities, Internet enterprises, venture capital institutions, etc. In this process, I created the WeChat community "IPFS Linden community", and dedicated to the construction of IPFS/Filecoin in China.So far, we have held many online AMA and offline salon activities, and continue to produce related original articles and videos, to promote IPFS/Filecoin project. For instance, "the most authoritative IPFS&Filecoin Knowledge Popularization" video is widely spread in the industry, with up to 50W+ views.

In 2019, IPFS/Filecoin became a industry and gets really hot in China, at the same time blockchain industry is getting mess with lots of chaos, to build a clean environment for the development of blockchain industry in China, I called for establishment of China Association for promotion of private Sci-Tech enterprises - Distributed Storage branch(http://www.cappse.org.cn/).
At the same time, Linden is appointed by China distributed storage blockchain Technology and Testing Standardization Working Group.
As the founder of Linden, I won the First Outstanding Committee Award from China Communitcations industry Association(http://www.ccia.org.cn/) blockchain professional committee
Our team have keep making contributions to the IPFS/Filecoin industry.

Diversity and Decentralization

Use Case Diversity

(Optional) Any additional information you'd like to share about the use case(s) you plan to support?

Within the scope of legal compliance, my team supports the application development of real data storage, mainly providing data storage solutions for enterprises and individuals. Including but not limited to video storage, document storage, image storage, enterprise disaster backup storage and other subdivisions. At present, Filecoin Plus is still under testing. I will focus on the process and conduct follow-up research and analysis according to the actual situation. I hope that the application i develop can alleviate or even break the development bottleneck and dilemma of data storage, and actively create a valuable Internet world.

Allocation Plan

Concreteness of Allocation Plan

Allocation Strategy

How do you plan on allocating the DataCap requested above? Please describe your allocation strategy with as much specificity as you can.

The great vision of the Filecoin network is to store the most important information for humanity, so the key for allocation is to develop an appropriate standard to evaluate the weight of each piece of data. In the early stage, my main goal is to develop enterprise-level customers and help them to use Filecoin network. I will make a comprehensive assessment of these customers' reputation, data nature, data size and other influencing factors, and finally allocate them according to the following rating rules and weight ratio.(100 points in total)

1． Reputation of data providers: 10%
2． Nature of data: 20%
3． Data size: 20%
4． Importance of data: 15%
5． Contribution to the community: 5 %
6． Customer data storage management system: 10%
7． Social background of data provider: 5%
8． Data management investment and accumulation of r&d: 5%
9． Equipment input: 5%
10． Growth rate and customer quality: 5%

I will nominate more than 5 internal notaries to score users according to the above assessment rules and weight ratio, and finalize the score of users to establish a reasonable allocation scheme.

Are there any internal processes you plan on impelementing regarding the target, amount, or rate at which you'll allocate DataCap?

I will nominate more than 5 internal notary staff, on the basis of the rational distribution plan, assign users in batches.I plan to add the above assessment rules to the internal process, and constantly explore our practical application value based on the dynamic balance process of Filecoin network, develop and reward the application with reasonable compliance, so as to encourage the benign development of IPFS/Filecoin ecosystem.

In order to build business applications, I will also continue to focus on several data storage applications:
1.Enterprise data storage, disaster backup storage (e.g., medical imaging, insurance industry, astronomy and geography);
2. Personal data storage (videos, pictures, documents and other data);
3. Important data native to various blockchain host networks (related to blockchain, smart contracts, open finance).

How do you plan on securing the DataCap to ensure your organization (and its delegated members) are the ones allocating the DataCap?

The security and rational use of DataCap is the core of notarization.Therefore, in terms of security, I will establish a security team of no less than 5 people within the organization and implement reasonable audit mechanism.During the test period, I will establish a platform for notarized public information disclosure and supervision on GITHUB, and launch a verification tool to promote the fair and just of our audit results through multiple measures such as an authorized multi-signature platform.

Client Due Diligence

How will you vet your Client to ensure they are spending that DataCap responsibly?

Step 1: Register and back customer information
I will register customer information. Participants are required to provide the following information:
- Business license;
- Legal person information, including ID card, ID card photo, mobile phone number, mobile phone verification code;
- Signature of legal person or agent
- Compliance application commitment
- Detailed application materials and historical evidence
- Complete the data cap plan within at least one year
- List of relevant historical products.
- Number of users in the existing user community, user portraits, etc

Step 2: Grade assessment
I will score the weight ratio for users according to the set customer scoring rules. We will truly assess the reliability of the data provider and the nature of the data, etc., to ensure the quality of the provider and its data. Then I will distribute the data in batches, and finally dynamically adjust the distribution quantity according to the user's rating table.

Step 3: Make information public for verification
All of our ratings and distribution reports are publicly and transparently posted on GITHUB for review and supervision by participants.
We will also introduce a feedback mechanism to collect suggestions or complaints for improvement.After gathering and reviewing the above information, participants will use the DataCap in a reasonable and efficient manner.

What questions will you ask to ensure the Client can properly handle the DataCap you intend to allocate to them?


1. What is the main direction of your application?
2. What is the current development plan for the application?
3. What is the organizational structure of your team?
4. What are the features of your application?
5. What areas will your app serve when it goes live?
6. How to reflect the promotion mode of the application after going online?

What processes will you employ to confirm that a Client is not improperly over-allocating DataCap to a single entity?


Ecosystem construction still needs good systems and procedures to ensure that the work of notaries can be carried out in a fair and transparent environment.Every notary should proceed with caution and pragmatism.Our investigation and review team will closely monitor and track the use of DataCap.Once the problem is found, it will be responded in time, and the illegal use will be severely punished.Second, open oversight mechanisms allow mutual oversight.If it is found that the distribution is unfair, it can be reported and deal with it strictly after examination.

Bookkeeping Plan

Do you plan on keeping records of your allocation decisions? If so, with what level of specificity do you intend to respond to any audit requests?

We fully support documenting the entire assignment and Posting notarized information on GitHub to ensure transparency and credibility.

Do you plan on conduct your allocation decisions in public (e.g. Github repo), private (e.g. over email, Telegram, etc), or both?

As a Datacap notary, it is necessary to notarize the information.We will make a public distribution on Github. We must uphold the principles of fairness, transparency and openness.
