VNT WEEKLY, December 10

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. Dr. Chen Jianhai, head of InCAS-LAB, the joint blockchain laboratory of Zhejiang University and Zhejiang University, published a paper “A Truthful FPTAS Mechanism for Emergency Demand Response in Colocation Data Centers” at the top ranked conference IEEE INFOCOM 2019.

Aiming at the problem of emergency demand response in the field of energy supply in the Cloud Data Center, the paper designs a deterministic mechanism and algorithm to let lessees of the data center participate in bidding and obtain compensation, and then contributes resources by saving energy to finally meet the emergency response demand.

At the present stage, the paper focuses on the contributions in theory, algorithm and the realization of simple system and there is little discussion on the safety of the reverse bidding system. Follow-up research focus is to use blockchain technology to enhance the security and credibility of the bidding system and design a kind of excitation mechanism of blockchain to make tenants more active in responding to emergency demand, which is of great significance for improving better energy management system of data center or price mechanism of distributed power grid market.

2. On December 6, VNT Chain and Bihu announced their official strategic partnership.

Bihu is an outstanding community platform for content of blockchain and has a relatively perfect community infrastructure, which forms a great cooperative relationship with VNT Chain community ecology.

Community Updates

Looking back at 2018, we experienced some twists and turns and achieved a lot of gains. And such a winter that many people are afraid of is precisely the opportunity for us to correct the past and achieve transcendence.

Together, we crossed the cold winter and greeted the warm spring.
