VNT WEEKLY, September 2

This is the weekly report of VNT Chain in which you will find about the latest project updates, community news and development progress. It would be a great honor for us to share exciting news and build the ecology with you!

Project Updates

1. On August 26, [Chainge] the 10th Technical Salon — The Application of Sidechain & Cross-chain Technology in Blockchain Industry, was successfully completed. Yang Wenlong, chief architect of VNT Chain, made a wonderful speech on “Aggregation Chain: New Trends in Blockchain Technology Development”. Yang Wenlong said that there is token on the public chain and data on the consortium chain. What VNT Chain aims to do is to transfer the token from public chain to consortium chain and data from consortium chain to public chain through the application of cross chain.

2. On August 31, the VNT Developer Platform was first opened for small-scale testing. As the technical service provider of this Bitrun activity, VNT Chain provides a developer platform to provide blockchain infrastructure services, node status monitoring, block information display, contract management and other functions for developers participating in the competition. At the same time, the team that developed on the VNT developer platform won the second prize in the competition.

3. VNT Chain [Block Theory] Series Salon is under preparation! We will gather enthusiasts of cryptography, digital currency, blockchain and other technologies to discuss the blockchain, and at the same time provide participants with a technical communication platform to promote communication and integration. This is a discussion salon for top blockchain developers, and also a space meant for passion collision!

Community News

1. On August 31, the first BitRun Hackathon supported by VNT Chain, which gathered the most active blockchain developers, has officially launched in Hangzhou Xixi Valley. In this event, 15 teams from dozens of computer technology and general economic design talents from Tsinghua University, Peking University, Zhejiang University, Tongji University, Wuhan University, Imperial College, Ibm and Huobi Research Institute will be conducted in the form of sub-component theme development and then represent the final works. The winning teams and works will be selected through professional judges composed of authoritative experts in the industry, CTOs of well-known enterprises and partners of investment institutions.

At the opening session, co-founder of VNT Chain Zhou Feng shared his understanding of the practice of blockchain scenarios by making a speech on “The Exploration of the Next Generation Public Chain”, and explained the important value of the emergence and improvement of aggregation chain architecture, which accelerates the realization of multi-scenario application.

In order to enrich the content of the competition and provide more development options for the participants, the organizer provides multiple development platforms for all participating teams. Among them, the VNT developer platform, AKA VNT consortium chain application development platform, provides developers with blockchain infrastructure services, node status monitoring, block information display, contract management and other functions.

2. The first anniversary of “September 4” is about to open. What kind of surprise will VNT Chain give as the sole sponsor of the event? If you want to know what's going on, please keep paying attention to our WeChat public account!
