The QuarkChain consists of two layers of blockchains. We apply elastic sharding blockchains (shards) as the first layer, and a root blockchain that confirms the blocks from the shards as the second layer.
Cross-shard transactions can be issued at any time, and confirmed in minutes. The throughput of cross-shard transactions increases linearly as the number of shards increases.
We designed a game theoretic framework for incentives, where hash powers are incentivized to distribute evenly among shards. There are at least 50% of overall hash power allocated to the root chain to prevent double spending attack.
Last week, we officially announced the launch of QuarkChain testnet 2.0 with mining. We summarized all the questions related to the Testnet 2.0 mining function. If you have any other tech-related questions, welcome to join us on Discord. https://t.co/ng5OK64Mso
