Project Updates

Blockchain security meet up conference review

On the afternoon of August 28th, VNT Chain technology community and Yunphant held a meet up with the theme of “Blockchain Security”. The conference was hosted by Dr. Huang Butian, founder of Yunphant Blockchain and co-founder of VNTChain, and invited Wan Zhiguo, associate professor of the School of Computer Science and Technology of Shandong University, Shi Taibin, head of Yunphant Blockchain Infrastructure R&D, and Department of Software Engineering, Zhejiang Gongshang University Dean of the VNT Chain Technology Community Chief Scientist Dr. Liu Zhenguang, Chengdu Lianan co-founder Associate Professor Guo Wensheng, Yunxiang-Zhejiang University Joint Blockchain Laboratory Head Associate Professor Chen Jianhai and other guests, from the zero-knowledge proof account model, the People’s Bank of China Financial District Blockchain security evaluation standards, smart contract security and network protection, smart security vulnerability detection, and blockchain security & cross-chain research progress are shared. Tightly integrate the VNT Chain aggregation chain architecture, and explore in-depth the extreme requirements for blockchain security in the “consortium chain + cross chain + public chain” business application scenario. Last week we sorted out the minutes of the 4-hour meeting, and extracted the essence of each guest’s shared theme, and shared it with everyone here.

ACCPT Meetup

On September 10th at 10:00am Beijing time and 12:00pm Melbourne time, VNT Chain, Yunphant Blockchain, Swinburne University of Technology, Digital Research Innovation Capability Platform (Swinburne University of Technology, Digital Research Innovation Capability Platform) held ACCPT Meetup, Dean of Digital Innovation Research Institute of Swinburne University of Technology (SUT) in Australia, Xiang Yang, Chair Professor of Yangtze River Scholars of the Ministry of Education of China, Dr. Huang Butian, founder of Yunphant Blockchain/co-founder of VNT Chain, co-sponsored by VNT Chain Zhou Feng and related core technology developers participated in the meetup. This meet-up mainly revolves around ACCPT’s three-layer cross-chain service, cross-chain information exchange layer (C2IE), cross-chain-based decentralized asset information exchange layer (C2AE), and cross-chain-based decentralized transaction service layer (C2TS). Better achieve frictionless cross-chain asset transactions and high-value digital asset mapping and other related issues.

Yunphant won the bid for the blockchain project of Shanghai Futures Exchange

On September 10, 2020, Hangzhou Yunphant Network Technology Co., Ltd. successfully won the bid for the blockchain project of the Shanghai Futures Exchange. This is another national-level financial blockchain infrastructure that Yunphant has undertaken this year following the “Credit Assets Registration and Circulation Blockchain Platform” project of CCDC.

In order to further meet the development needs of the physical industry and better serve the real economy, Yunphant assists the Shanghai Futures Exchange to build a basic blockchain platform for the Shanghai Futures Exchange. The platform will use the cloud image financial consortium blockchain technology to digitize, informatize and standardize the inherent attributes, logistics attributes, and legal attributes of the commodity futures listed on the Shanghai Futures Exchange. The consortium chain mechanism for verifying information takes “trustworthiness” as the core and establishes a bulk commodity information system with non-tamperable information as the main symbol. Based on the architecture of the consortium chain, it realizes information sharing and mutual certification with external agencies such as customs and warehouses. On the basis of ensuring the accuracy and safety of information, it realizes some data presentation functions, such as warehouse receipt logistics, finance, information and other attribute data presentation.

The latest research results of VNT Chain are listed in the top journals of CCF Class A

The paper “BlockMaze: An Efficient Privacy Protection Blockchain Account Model Based on zk-SNARKs” jointly researched and published by the team of VNT Chain Technology Community, Yunphant Blockchain Research Center and Associate Professor Wan Zhiguo of Shandong University School of Computer Science and Technology Accepted by TDSC, the IEEE Trusted and Secure Computing Transactions, TDSC is one of only three A journals in the field of information security recommended by the Chinese Computer Society (CCF). The latest impact factor is 6.864. The Chinese Academy of Sciences is a district in the world. A well-known authoritative journal in the field of information security. This paper proposes an efficient privacy protection blockchain account model based on zk-SNARKs-BlockMaze for the account model, which is the world’s first blockchain native solution for the account model that fully protects transaction privacy.

Dr. Huang Butian and Dr. Liu Zhenguang were both selected as expert members of Hangzhou Blockchain Technology and Application Association

On September 25th, Hangzhou Blockchain Technology and Application Federation issued the annual expert member announcement, which was voted by the special committee. The founder of Yunphant Blockchain VNT Chain co-sponsor Dr. Huang Butian and VNT Chain Chief Scientist Dr. Liu Zhenguang were both selected Member of technical expert group.

The Hangzhou Blockchain Technology and Application Federation (hereinafter referred to as the “Federation”) was established on June 16, 2017. It is composed of related enterprises and individuals (managers, scientific researchers, etc.) engaged in blockchain technology and applications. Formed local, comprehensive, non-profit social organizations. The Federation accepts business guidance, supervision and management from the financial work office of the Hangzhou Municipal People’s Government, the business supervisory unit, and the Hangzhou Civil Affairs Bureau, the social organization registration management agency.

VNT Chain zero-knowledge proof BlockeMaze interpretation version released

We announced the latest research results of VNT Chain in privacy protection and zero-knowledge proof technology “BlockMaze: An Effificient Privacy-Preserving Account-Model Blockchain Based on zk-SNARKs”. This paper proposes a method for the account model blockchain. BlockMaze, an efficient privacy protection solution based on zk-SNARKs zero-knowledge proof, was accepted by TDSC, the top CCF A-class journal in the field of network and information security. This article explains in detail the specific research content of the program.

“Industrial Blockchain” Publishing Online Conference

On September 24, 2020, the “Industry Blockchain” online press conference was launched. Among them, Dr. Huang Butian, the founder of Yunphant Blockchain and the co-sponsor of VNT Chain, was invited to participate in the conference with several guests. .

“Industrial Blockchain” was co-written by 20+ domestic blockchain industry experts from the World Bank, China Development Bank, Zheshang Bank, Tsinghua Yangtze River Delta Research Institute, Canaan Technology, Yunphant Blockchain, etc. In-depth analysis of the strength of blockchain in 19 industries in the dimensions of, technical architecture, and trial plans, which is comprehensive, representative and time-sensitive. Dr. Huang Butian participated in the case writing of industrial blockchain + supply chain finance, and carried out a comprehensive analysis based on the industry background, landing cases and current policy support.
