Welcome to the 20th QuarkChain Bi-weekly Report for the period from Nov. 30 to Dec. 13.

1. Development Progress

Our engineers have been actively improving the testnet 2.0 and publishing new releases based on the feedbacks and comments from our users. Here is a list of major updates:

Added timeout logic in the block synchronizer so that the cluster will give up syncing from slow or unresponsive peers and switch to a better peer instead. Fixed a memory leak bug in the P2P layer Ran QKCHASH in native code significantly reducing the block validation time Added a page to the testnet 2.0 website to show the mining results in real time A snapshot of the database is uploaded every 12 hours by the team. New cluster can opt to download and use the database directly instead of syncing blocks from the genesis blocks. Built a tool to guide users through creating an address for mining, starting a cluster, syncing blocks, and prompting users for mining when blocks are synchronized with the network.

2. qPocket Mobile Wallet V 1.0.0 official launch

3. Testnet 2.0 Mining Event

Testnet 2.0 further improves the openness of the network. Users who participate in the mining of the testnet and obtain the test tokens (tQKC) can be converted to QKC of the mainnet in a certain ratio after the launch of mainnet (note that Country restriction). Please find more details here:

4. Partnership

4.1. QuarkChian works together with Bitape and Global Idol Coin to create Upstream and Downstream Ecology of BlockChain

QuarkChain shakes hands with Taiwan’s most promising blockchain intelligent tracking-Bitape.
