The project design makes full use of Yunphant’s core technical experience and integrates multiple smart Asian Games scenarios such as blockchain tickets, blockchain torches, and blockchain volunteers. The relevant technical solutions have been highly praised by the Hangzhou Asian Organizing Committee and review experts. And fully affirmed.

Yunphant participated in two projects and was approved as a key project by the Hangzhou Municipal Committee of Jiu San Society in 2020

Recently, the Hangzhou Municipal Committee of Jiu San Society has issued a 2020 key project notification. The committee meeting of the Economic, Social, and Municipal Committee of the People’s Republic of China identified 11 topics as key topics for 2020 from among the many declared topics. Among them, Yunphant participated in the “Creating a National Benchmark City for Social Governance Modernization in the City Area” to improve the level of digital technology and accelerate the modernization of city governance. ”And “Improving the Level of Social Governance through Digitalization” both projects have been approved as key projects by the Social and Municipal Committee in 2020.

It is reported that “Creating a National Benchmark City for Modernization of Municipal Social Governance-One by One, Improving the Level of Digital Technology and Accelerating the Modernization of Urban Governance” is a special democratic supervision project of the municipal party committee. The application of new generation information technologies such as networking, artificial intelligence, 5G, and blockchain in urban governance will help Hangzhou improve the modernization level of urban governance capabilities and build a modern benchmark city for urban social governance across the country. “Improving the level of social governance through digitalization” is a key topic of the Social and Provincial Party Committee. The Hangzhou, Hengzhou, Wenzhou, and Taizhou Municipal Committees will jointly participate in cross-regional linkage to promote the construction and application of smart city brains, and use new generation information technology to further improve the modernization of urban governance System, promote digitally empowered city management, and improve social governance.

VNT Chain co-founder Zhou Feng was invited to participate in the keynote speech of “Industrial Blockchain Conference NO.12”

On August 6, the 12th community live broadcast of “Industrial Blockchain Talks” hosted by Milin Finance started as scheduled. The topic of this issue is: The topic of this issue is: public chain, alliance chain, aggregation chain, who can stand out in commercial applications? Zhou Feng, co-founder of VNT Chain, was invited to share the theme. Zhou Feng mentioned in the keynote speech that we adopt the “consortium chain + cross chain + public chain” aggregation chain technology architecture, hoping that this architecture can better empower the distributed economy, and promote the block from the technical and commercial levels. The industrialization of the chain industry builds a connector for data exchange and asset exchange. The public chain represents our exploration of technology and the future empowerment of liquidity in business scenarios. The alliance chain is what we use to implement the scene. The cross-chain part is for us to realize the exchange of information, data, and assets.

The second phase of Yunphant Academy started

Last week, the second phase of Yunphant Academy jointly initiated by Yunphant Blockchain and VNT Chain was officially launched, mainly including Golang syntax explanation, chain code testing, smart contract explanation, SDK and chaincode deployment and other related content. Among them, Golang is the main language of the VNTChain core code. We hope that by strengthening the learning and sharing within the team, the technical team can better understand the VNT core code and improve team collaboration efficiency.

Yunphant Academy is jointly initiated by Yunphant Blockchain and VNT Chain. It aims at the company’s internal employees through knowledge training, case sharing, technical practice (public chain, alliance chain, cross-chain) and other methods to improve the company as a whole The team’s industry awareness, personal skills and team consensus.

Upload the first batch of VNT-SGX code to Github

Last week, the first batch of VNT-SGX codes have been uploaded to VNT github. SGX technology is one of the four core technology development directions of VNT Chain. We have developed in-depth VNT Chain’s aggregation chain architecture, taking security, privacy and efficiency as the first priority, in the four directions of smart contract security, data privacy protection, blockchain software architecture, and SGX data protection.

This technology is used to protect the privacy and security of the transaction process on the blockchain. The blockchain transaction verification and transaction construction method based on the full node will expose the transaction information of the lightweight client of the blockchain to the full node server together with the client information, and the privacy of the user cannot be guaranteed. The SGX technology will be used on the full node server, the SGX security zone will be deployed to protect the transaction processing process of the full node, and the ORAM technology will be used to provide local secure storage to ensure that user data from the lightweight client will not be on the full node server during the communication process Stolen by any third party and full-node server manager.

Dr. Huang Butian was invited to participate in the “Huobi University”

At 20:00 on August 21st, Huang Butian, founder of Yunphant Blockchain, co-founder of VNT Chain, and Ph.D. of Computer Science at Zhejiang University, was invited to conduct “Financial Assets On-chain Application and Technical Practice” in the live broadcast room of the leading class of Huobi University This is also the second lesson of the asset chain lecture hall. Huang Butian said that the blockchain will promote the wider development of the digital economy, making data a key factor of production, and changing the storage and transaction forms of assets. Asset on-chain refers to the process of mapping assets in the physical world to assets on the blockchain. The entire process includes asset definition, asset selection, asset confirmation, and asset mapping. Asset on-chain is an inevitable choice for a truly digital economy.

VNT Chain has made major technological progress in heterogeneous cross-chain

Recently, VNT Chain has made significant technological progress in cross-chain. The paper “ACCTP: Cross Chain Transaction Platform for High-Value Assets” jointly researched and published by the VNT Chain Technology Community, Swinburne University of Technology Blockchain Innovation Laboratory, and Yunphant Blockchain Research Center, was selected into ICBC 2020, an international blockchain academic conference hosted by the Services Society. Based on the high-value asset blockchain platform for cross-chain technology research, this paper proposes a heterogeneous cross-chain innovation model, ACCTP, to realize information sharing and asset circulation between different blockchain networks, and overcome the problem of cross-chain asset transactions.

Blockchain security meetup

On the afternoon of August 28th, Yunphant Blockchain & VNT Chain jointly organized a meetup on the topic of blockchain security, and invited major blockchain laboratories in the VNT Chain technology community, including Zhejiang University, Shandong University, Zhejiang Gongshang University and Chengdu Chain Security. We discussed various aspects of smart contract security and network protection, central bank financial blockchain security evaluation standards, zero-knowledge proof account model, smart security vulnerability detection, blockchain security and cross-chain research progress. The topics were closely focused on the VNT Chain aggregation chain architecture, in-depth exploration of the ultimate demand for blockchain security in the “consortium chain + cross chain + public chain” business application scenario. For business scenarios, trust is the foundation and security is the gate of life. We will make best effort to explore and verify such technologies.
