1)QuarkChain PoSW Mining Event

PoSW model precisely helps both token holders and miners to attain their objectives. Once the miners meet the requirement of staking, the benefits of mining on QuarkChain (converting to market price) exceed mining returns from Ethereum under the same level of hash power. The benefit can be 5 times higher than the one on Ethereum. In order to enable more people to join the mining and staking, we have prepared three fabulous tools and one favorable news enabling both miners and holders to gain outsized mining returns. Details.

2) BTC/QKC exchange was listed on Gate.io

BTC/QKC exchange was listed on Gate.io on September 1, 2019 (Beijing Time). To show our gratitude to the supportive QuarkChain users, QuarkChain and Gate.io hosted 2 Million QKC Reward for Trading Competition and Special mining event from September 1 to September 5.

QuarkChain CMO Anthurine discussed the future and development of the blockchain industry with representatives from these blockchain projects. She said QuarkChain’s underlying architecture is designed to be flexible enough. The basic idea is that each shard can have its own consensus, VMs, and token economics as needed. If a new consensus algorithm is developed in the future, we will add another shard to be fully compatible with the new consensus, which enables us to keep up with the new updates.
