It has been said that career development is like a marathon. What is it like to insist on running a marathon? Cui Ran has a great say.
Cui Ran, who has been engaged in development work for more than 10 years, is now a senior engineer of Tencent Technology (Beijing) Co., Ltd., deeply involved in the field of blockchain. In his spare time, he insists on participating in marathon events for a long time. During the constant running, Cui Ran lost more than 20 kilograms of weight, and also found the meaning and joy of persistence.
"Marathon makes me healthier, and focus and persistence make me go further in technology." From a basic technician to a senior engineer in a large factory, to a blockchain developer who wrote more than 30 patents , MVP of the FISCO BCOS open source community, Cui Ran summed up the secret of growth as: keen insight, focus and enthusiasm for technology, and tireless learning.
Most technicians are reserved and low-key, and so is Cui Ran. However, FISCO BCOS made him more "extroverted". After joining the community, more than 30 like-minded friends have been added to his "developer circle of friends", and he often initiates technical exchanges on his own initiative. At Station B, Cui Ran continued to publish a series of video tutorials on FISCO BCOS combat, with a total of over 10,000 views. As an MVP, Cui Ran is very enthusiastic and good at maintaining contact with technical personnel in different fields, and is enthusiastic about answering technical consultations, establishing a "personal brand" of technology for herself.
The following is the actual interview with Cui Ran:
Blockchain gives me the opportunity to realize more social value
1. Briefly introduce how you became acquainted with blockchain and why you chose blockchain technology?
I joined Tencent in 2017 to do some business in security scenarios. In 2018, we hoped to introduce blockchain technology, so we began to pay attention to blockchain technology and platforms at home and abroad, especially the technical principles related to user identity. During the process, I came into contact with FISCO BCOS. At that time, I learned that WeZong Blockchain provided open source technical support for the Guangdong-Macao Health Code Cross-border Mutual Recognition Project. This project applied FISCO BCOS and WeIdentity, a distributed digital identity solution independently developed and open source by WeZong Blockchain. WeIdentity was related to our business at that time. Based on this solution, we made our first product.
The main reason for choosing blockchain technology is that blockchain technology itself is non-tamperable, distributed, and multi-centered, which is naturally suitable for the security field I am engaged in, and has the value of in-depth research.
2. Before you engaged in blockchain technology development, you also worked in other fields for many years. In your opinion, what is the difference between these jobs and blockchain development?
The biggest feeling that doing blockchain brings me is a sense of value and a sense of accomplishment. In the past, I did a lot of security development work, but I focused more on the technology itself, and I always felt that the combination of technology and applications was relatively "shallow". After entering the blockchain field, I participated in the development of more valuable products, and felt more clearly how technology can bring changes to industries related to society and people's livelihood, such as copyright, agriculture, and public welfare, which gave me a lot of experience. Great sense of accomplishment.
3. Have you encountered any difficulties in the transformation of blockchain development? Any advice for other developers looking to make the transition?
I did encounter some difficulties when I first came into contact with the blockchain. There is no one to guide you when you get started, and there are relatively few relevant communities and materials, so it is inevitable to take some detours. Later, I came into contact with the FISCO BCOS open source community. The introduction and documentation of the community were more detailed, which allowed me to find a better path to learn and solve problems. At that time, I also went to Shenzhen on a business trip, and kept communicating with technicians, architects, and operation sites in our community. Over the years, we have also conducted many online exchanges, and have a deeper understanding of the platform and products. learn.
Therefore, I suggest that developers who transform the blockchain must first stick to their original intentions. The blockchain itself is a relatively hot field, and I believe there will be better prospects in recent years. However, there are also some impetuous voices in the industry, and some people came in with an opportunistic mentality. Under such circumstances, I hope that our technicians can calm down, return to the essence and original intention of technology, and truly apply this technology to all aspects of food, clothing, housing and transportation to benefit the society and people's livelihood. Secondly, it is necessary to go deep into the industry, communicate more with people in the circle, attend more online and offline meetings of the industry, and listen to the opinions of industry leaders.
The Internet allows information to be transmitted efficiently, and blockchain allows "trust" to be transmitted efficiently
4. Which blockchain projects are you involved in? How is blockchain technology applied in it?
I have participated in projects such as copyright deposit certificates and traceability of characteristic agricultural products. In the past, copyright protection was a problem, and the works published by authors were easily plagiarized. The blockchain technology provides a new solution: the application of the copyright deposit project is based on the formation of an alliance chain by notary institutions, judicial appraisal institutions, regulators, and other relevant parties. Different institutions play different roles and jointly protect copyright.
For example, the copyright holders of some popular TV series found that many small websites put videos on the shelves without obtaining permission to broadcast them, which is a kind of copyright infringement. In the past, it was very difficult to obtain evidence for this kind of infringement, because these small websites would take off the shelves and delete videos from time to time, erasing the traces of previous infringement, making the platform's subsequent reporting and rights protection very passive.
But things changed after we introduced blockchain technology. As long as these websites have played videos in violation of regulations, we can use automatic screen recording technology to record the violations of these small websites, and then upload these evidences to the chain to achieve legal evidence collection of infringements. The process of legal evidence collection must comply with special regulations. For example, the equipment for recording evidence collection must have the relevant qualifications of judicial appraisal or notary office, so as to prevent the video from being tampered with by malicious editing and ensure the authenticity and legality of electronic evidence.
5. What application scenarios do you think the blockchain can expand to?
There is a lot of room for imagination in blockchain applications. For example, after the use of blockchain technology in the public welfare field, the entire public welfare ecology will be more transparent and credible. The flow of these public welfare projects and the donation records of each user will be stored on the chain, and a subsequent transaction will be formed based on the user’s donation record. According to this transaction, a certificate can be presented to the user. The whole process realizes that donations can be uploaded to the chain. Evidence can be stored, information can be traced, feedback can be reached, and multi-terminals can participate.
In addition, blockchain technology has a good application space in various fields, including games, entertainment, smart cities, smart transportation, government affairs management, mobile medical care, etc.
6. You have been in the industry for ten years, and you must have witnessed the changes in Internet technology. In your opinion, what is the difference between blockchain technology and the Internet technology in the past?
The Internet is used to transfer information, and the blockchain is used to transfer value. To put it simply, the Internet solves the efficient transmission of information, and the blockchain solves the efficient transmission of "trust".
For example, the account reconciliation business of the bank's remote authorization system that I have done before is very cumbersome to implement before blockchain technology: a corporate account will generate a statement every month, and we need to put the account information including balance details Print it out and send it to the company by courier; the company will confirm the information with a receipt after receiving it, and send the receipt back to the bank if there is no problem. Our system also needs to scan and enter the signed receipt form of the enterprise into the system, and some problematic statements need to be processed again.
But now with blockchain technology, the whole process will be very convenient. Account information can be shared during bank reconciliation, transaction data can be synchronized in seconds, and real-time reconciliation can be completed in a very short period of time, realizing the "trust" Efficient delivery.
Engage in technology, but also develop a personal brand
7. When and how did you learn about FISCO BCOS? What new friends have you made after joining FISCO BCOS?
Since I came into contact with the blockchain, I began to study the current alliance chain in China. At this time, I saw the relevant information of FISCO BCOS, and found that it was one of the few at that time, and it was very leading in technology, application, ecology and other aspects. Open source alliance chain. After choosing to join FISCO BCOS, the first contact was with the developers responsible for the underlying technology, and they learned about the underlying content. Later, they came into contact with some open source projects in the community, including WeBASE enterprise-level middleware, data export, and on-chain management. In this process, I met many experts in the community. In the past few years, the community has had many activities in Beijing, and I often participate in them. I feel that I have benefited a lot from the close contact and chat with these experts.
8. You have been actively participating in open source evangelism, and have set up video tutorials such as FISCO BCOS practical applications on platforms such as station B and CSDN. Tell us about your original intention and understanding of recording tutorials?
This is one of the things that I realized deeply after coming into contact with the community. To be honest, when I first recorded the FISCO BCOS tutorial, I just wanted to review and sort out the knowledge points to facilitate my own learning. In addition, I think that if technology practitioners want to achieve better development, they must build their own brand influence and become experts in this field. But in fact, I am usually introverted and not good at expressing. In the process of making videos, I also exercised my ability to express and present content.
After the video was released, I gradually found that I helped many technicians who are engaged in this field like me, such as some students who are doing papers and graduation projects in colleges and universities, researchers doing related technical research, and some technical experts from the community. Workers or enterprises, I am also happy to share with you the pitfalls and experiences I have stepped on. When encountering a lot of questions from everyone, I will write some articles and publish them for everyone to view. In the process, I have also met more like-minded friends who are passionate about technology.

9. There are also many people in the community who want to participate in evangelism, but do not know how to start. Do you have any suggestions and experiences to share?
I can’t even talk about the experience of evangelism, just a little insight. I think technology sharing needs to start from the perspective of technicians, and share technology-related content without reservation. Making a video is also a process of systematic thinking. It is better to tell everyone the process of how to achieve it than to simply tell everyone the result. This will make it easier to understand the essence of the technology behind it. It is better to teach people how to fish than to teach people how to fish.
10. As the MVP of FISCO BCOS open source community, how do you understand MVP? Do you have any plans to participate in open source co-construction in the future?
Being the MVP of FISCO BCOS gave me a lot of confidence, and I feel that my efforts have been recognized. In the future, I will keep up with the updates of the platform and get a deeper understanding of the technical details; I will continue to pay attention to the dynamics in the group and GitHub to see what problems you encounter, and answer them within the scope of my ability. Sharing, after all, the process of helping others is also improving yourself.
Since the establishment of the open source community, it has attracted many technology enthusiasts who love to share and communicate. In order to thank everyone for their support and contributions to FISCO BCOS along the way, the community has opened the FISCO BCOS MVP certification to encourage FISCO BCOS opinion pioneers and opinion leaders who contribute high-quality technical content to the open source community.
Since its launch, the community has identified 26 MVPs, covering experts in various fields such as cultural copyright, intelligent construction, supply chain management, and the Internet of Things. The development of the community is inseparable from every developer. We look forward to partners in more fields sharing ideas, colliding views, and interoperating technologies to jointly promote the vigorous development of the industrial blockchain. In the first half of 2022, the FISCO BCOS MVP certification channel has been opened, and everyone is welcome to click the [ link ] to apply enthusiastically. At the same time, in order to let everyone better understand and understand MVP, the community launched the "Dialogue MVP" column, which will take you through the Q&A to understand what MVP feels and understands in the blockchain field.
