1. Development Progress

While the current testnet gets relatively stable, engineering team is focusing on planning and designing key features slated for the mainnet, experimenting with new ideas and constantly improving the current code base.

1. Drafted the implementation for multi-native tokens on our testnet 2.0;

2. Designed a better shard ID representation which helps to implement re-sharding;

3. Designed and simulated Proof-of-Staked-Work (POSW) consensus algorithm to better secure the network against double-spending attack, and also proposed corresponding implementation plan;

4. Finished external miner command-line tool in Go, which will be released soon;

5. Finished mining pool integration for Ethash on QuarkChain clusters.

2.GPU Mining Guide

After the CPU mining for 1 month, we now announced that we open GPU mining to public! Regarding to setup GPU mining for Ethash (shard 0,1,2,3), more details can be found at: https://github.com/jyouyj/ethminer. Please build the binary on your own or use the provided AMI on AWS (https://github.com/jyouyj/ethminer#aws-ami).

Also the GPU mining binary release for Windows. Please refer to https://github.com/jyouyj/ethminer/releases/tag/QuakrChain_Miner_Windows_Binary_Release.

3. QuarkChain 2018–2019

Year 2018 is an important year to QuarkChain, from debut listing of QKC on Binance; to announcements of Testnets 1.0, 2.0 and open-source codes. In addition, QuarkChain mining event, bounty program is ongoing. QuarkChain has launched partnership with 70+ high-quality projects and QuarkChain ecosystem universe is continuing to expand. What’s more, CEO Dr. Zhou, CMO Anthurine, and some other team members held Asian Tour, European Tour and other offline events to meet community members closely.

4. Proof of Staked Work — A Simple PoW/PoS Hybrid Consensus

In this article, Dr. Zhou proposed a simple but secure hybrid PoW/PoS — proof of staked work (PoSW). The basic idea is that, if a miner wants to contribute its hash power to the network (suppose it is equivalent to p percent of all hash power of the network), the miner must stake the number of tokens that is proportional to p.

5. qPocket 2.0 update

qPocket 2.0 aims to provide users with a simple, secure, and fully functional portal to the blockchain. qPocket 2.0 officially launched the dApp Store function, which not only provides users with a better dApp experience on mobile phones, but also connects blockchain applications into an ecosystem.

6. Event

On Jan. 04, the conference “Blockchain value list of 2019” officially held in Hangzhou. The conference unveiled the seven blockchain value lists and the White Paper of the blockchain value list of 2019, jointly created by Babbitt and TokenInsight. In addition, the new book “Ten Years of BlockChain”, which was co-authored by 12 industry leaders in the field of blockchain, will be published. During the conference, QuarkChain was awarded one of the most valuable decentralized application platforms.

QuarkChain always appreciates the community’s support and company.
