- Dealt with a malicious transaction and fixed a bug in consensus；
- Fixed the nodes’ stalled issue when too many files were opened;
- Modified the redundant coinbase branch check in shard state;
- Shut down jrpc server properly when jrpc server context encounters test error;
- Improved our jrpc communication code to avoid blocking on each connection；
- Evaluated some options for performing third party code review and prepared the mainnet launch.
2. QuarkChain Guardian Plan Officially Released
QuarkChain Mainnet Singularity V1.0 will be officially launched on April 30, 2019. QuarkChain will be one of the first public chains which successfully implements high-throughput sharding technique in the world.
Guardian Plan has been launched to protect all community members’ interests and guarantee the security of QuarkChain mainnet with enough hash power. All community members are encouraged to apply as a guardian or vote for guardians through staking a certain amount of QKC. Elf Guardian expects to receive more than 300% annualized returns. Additionally, to show the good faith of QuarkChain team on the long term vision and mission of this project, QuarkChain foundation will match and stake the same amount of QKC during the Guardian Plan.
3. QuarkChain Announced the Official Open for Staking QKC for Votes
After constant development and test, staking QKC for votes officially opened. Users are allowed to stake QKC for receiving votes at the Guardian Plan page and earn the early bird rewards before QuarkChain mainnet launch. The Elf Guardian campaign will officially start in early April 2019.
