Since inception, QuarkChain has achieved many milestones. It has been almost 2 months since QuarkChain testnet 2.0 launched and runs stably. Enormous attentions haves been paid to project development in the past one year. Thanks to the community support, QuarkChain, as one of the most famous open source public blockchain projects, has received lots of thumb-ups from several code review agencies.

However, 51% attack was reported to happen on a few influential blockchain projects, which also suffer from security concerns. These events have given us serious alert. QuarkChain has been focusing on security design from the very beginning by applying rich prior industry experience. In addition, the launches of testnets 1.0 & 2.0, code review by professional agencies, organizing hackathon, and TPS competition also greatly enhanced QuarkChain network security. A strategic partnership was also reached between QuarkChain and Certik, which will provide QuarkChain a top-notch security verification solution to resist potential hacking for smart contracts on its public chains. Nevertheless, we deeply believe that solid consensus and security come from excellent community that is very helpful for QuarkChain to do better.

Therefore, QuarkChain will officially announce “Developer Bounty Program”. The main purposes of such event are to further enhance QuarkChain network security, offer the highest level of security of users’ property, and make QuarkChain the most secure project. Developers who find a bug, report a bug issue, and invite friends to join bounty program will receive high rewards. Details are given as follows.
