Fan Length: Trends in Pioneering Blockchain Research

On December 28, "The 1st Digital Finance Frontier Conference in 2021" was held online. The conference was organized by the Tsinghua SEM Digital Financial Assets Research Center and chaired by Professor Luo Mei, director of the center.Long Fan, Director of Shanghai Shutu Research Institute, Assistant Professor of Computer Science, University of Toronto, Canada, and Visiting Scholar, Center for Digital Financial Assets Research, gave a keynote address entitled "Frontier Research Trends of Blockchain".This sentence is designed based on the content of the statement.

First, we present the current state of research on the frontiers of blockchain. It's coming to an end.Currently, the front-end instructions for the blockchain are as follows:

First, more than 95% of the data is linked to public channels.The blockchain is divided into shared chains and public chains, and some wonder why so few people learn to share. The reason why string strings are a problem is thought to solve the problem. The complexity of the blockchain is proportional to the number of nodes, and in a typical application environment, the number of nodes required by a consortium chain is several or ten nodes. Many complex security issues in the blockchain are not a problem in this regard.

Now, for some reason, the benefits of the embedded chain system are really not a future-looking research problem, but an engineering problem, so most research focuses on the public chain. Public channels have more than performance, including security, industry standards, etc. The system is an open system and will have everything that can be learned. The public chains had to rely on their own stimulus model at the same time, and each public chain distributed tokens to control the symbiotic capital, which was also a disadvantage coordinated by internal scientists.

Second, in terms of overall research, the research results were presented with a focus on improving the performance of crypto root consensus algorithms for all public chains and smart contracts.Now, while blockchain performance issues have been gradually resolved, expansion issues have also been identified.

Third, current research is generally divided into three phases: the exploration phase, the fracture phase, and the development phase.Integrating all the technologies of our time, high-performance algorithms are the closest to development. Several obvious solutions have been developed. Blockchain is a distribution and once the shortest array of these processes has been solved, other factors such as storage, execution of smart contracts and network processes can be transmitted to make new bottles. This is why more and more people are now working on smart contracts and the implementation of a high-performance blockchain network P2P protocol.

Moreover, the wide application of public chains, especially the security of smart contracts, has become a problem where everyone pays more and more, and the benefits of security can never be undone because the road is always ahead. High and magical. a sheet of paper. For example, the DeFi ecosystem is now developing a new type of attack, such as the new FlashLoan, which is not only a disadvantage of security in the traditional sense, but a lack of funding in small budgets, or a lack of Business Development. .

Privacy and zero-knowledge proof are some of the things everyone has done on the blockchain. Since blockchain itself is a value transfer network, everyone wants to be a value switching network, so they always pay more attention to privacy than general information and how to use excellent privacy such that zero can be tilted. - Reduces the cost of proof of knowledge and can be used in practice.

He talked about his future decision on blockchain technology.

1. Solutions for the performance of the public channel will be put forward.After strong competition, many ways to use technology can now solve the problem. Despite the advantages and disadvantages, it is difficult to decide which is the best and which is the lowest, because this challenge is not entirely determined by the technology, but often combined by the investment of companies, by the use of technology alone.

2. The main theme that privacy uses technology, especially the combination of privacy number and blockchain, becomes obsolete.Indeed, privacy using technology has evolved from cryptographers studying only theoretical algorithms to scientists learning how to make private data count faster through the processing of cryptography, systems and compilers of the whole chain. High-performance smart contracts backed by zero-knowledge privacy technology will become a reality in the next few years. A completely anonymous and unmonitored stability coin can be found. Actually. This can create new problems for financial markets, ecosystems and policies.

3. Currently, blockchain research is generally driving application.Currently, there are two main directions for blockchain, one is DeFi applications affecting finance, which poses a greater risk to the security of smart contracts, and the other is The current direction of the metaverse should be made on the blockchain. Themes have been created on the Internet, some of the main content and some of the content is not, but new content is constantly being created. This will bring new challenges for blockchain storage, because blockchain storage space is very expensive, indeed, these applications will create security smart contracts and store or buy new research.
