Team Members Have Worked with Both Facebook and Google in Fields That Compliment This Type of Project. Today, lots of dApps are waiting for a more reliable and scale foundation to begin with, QuarkChain will become a perfect choice. “QuarkChain welcomes various DApps, especially those demand high transaction rates: advertisement, IOT ( internet of things), AI and big data, game, peer to peer sharing economy, etc. There are at least 50% of overall hash power allocated to the root chain to prevent double spending attack. We designed a game theoretic framework for incentives, where hash powers are incentivized to distribute evenly among shards.The throughput of cross-shard transactions increases linearly as the number of shards increases. Cross-shard transactions can be issued at any time, and confirmed in minutes.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. The QuarkChain consists of two layers of blockchains.QuarkChain welcomes various DApps, especially those demand high transaction rates: advertisement, IOT ( internet of things), AI and big data, game, peer to peer sharing economy, etc. (As a reference, Bitcoin blockchain only offers around 4 TPS.) Different solutions compel the community to split through a controversial hard fork. This problem is so urgent that the bitcoin community can’t wait to reach an agreement. The high-capacity system will solve the scalability problem that current main blockchains are facing. QuarkChain is a high-throughput blockchain that aims to achieve millions of transactions per second (TPS).
