About QuarkChain\nAs blockchain receives more attention from the masses and institutional investors,<br> we start facing issues that stay in the way of the implementation and adoption of the technology. Scalability and security do not go always hand-in-hand when it comes to blockchain technology. \n![ (https:\/\/steemitimages.com\/DQmQUS7zc1YsW6gLQkq1jJ4P1owYyn3am12KbMWMzrcVe3r\/image.png)\nQuarkChain have set out to find a solution that balances both scalability and security through by separating the two main functions of the chain into separate layers. \nThe first layer contains all minor blockchains,<br> or shards,<br> which process a sub-set of all transactions independently. As the number of shards increase,<br> so to does the number of transactions which can be processed concurrently.\nThe second layer of QuarkChain is the root chain. The primary function of the root chain is to confirm all blocks from the sharded chains,<br> but does not process transactions itself.\n![ (https:\/\/steemitimages.com\/DQmPCrdqizAXiTSsbP6VJJgPcxyA77aVZbzXZ4Y9om1cvR5\/image.png)\nQuarkChain allows for two types of transactions- in-shard and cross-shard. In-shard transactions occur between addresses on the same shard. However,<br> setting the QuarkChain ICO apart from other high-throughput solutions is the ability to conduct cross-shard transactions. The throughput of the cross-shard transactions system will scale linearly as the number of shards increases.\nUltimately,<br> blockchains that balance security,<br> scalability,<br> and decentralization will be more widely adopted. QuarkChain has the potential to be successful in this balance.\n\n# II. Features\n* Reshardable two-layered blockchain-Quarkchain consists of 2 layers. The first one offers elastic sharding (a type of database partitioning that separates very large databases the into smaller,<br> faster and easily managed parts called data shards). The second layer-also known as root blockchain- confirms the transactions (blocks) of the first layer. The second layer can also be resharded as needed without changing the root layer.\n* Guaranteed security by market- driven collaborative mining-basically,<br> to ensure the security of all transactions at least 50% of the overall hash power is allocated to the root blockchain preventing double spending attacks. This means that there will be collaborative mining (incentive mechanism) included.\n* Anti-centralized horizontal scalability- Quarkchain allows multiple cheap nodes that form a cluster to replace a super full node (that can be very pricey).\nEfficient cross-shard transactions. Two types of transactions: in-shard and cross-shard. In-shard transactions -when the input and the output addresses of the transaction are in the same shard. Cross-shard-when the input and output addresses are in different shards. The cross-shard transactions can be issued at any given moment and confirmed within minutes. The speed of the cross-shard transaction increases as the number of shards increases.\n* Simple account management- only 1 account needed for the all the blockchains(shards) in Quarkchain. All cryptocurrencies from different shards are stored in one smart wallet. A user will be able to manage all addresses in all shards via a single private key.\nQuarkchain will support smart contracts via EVM. Most of the existing DApps that are built on top of EVM can be directly deployed on Quarckchain. To utilize high-scalability,<br> Quarkchain will provide additional scalability-aware interface.\n\n# III. TokenSale\nTicker: QKC \nToken type: ERC20 \nICO Token Price: 1 QKC = 0.0229 USD (0.00003 ETH) \nHardcap: 20,<br>000,<br>000 USD \nTotal Tokens: 10,<br>000,<br>000,<br>000 \nAvailable for Token Sale: 20%\n![ (https:\/\/steemitimages.com\/DQmbPNwAkRyU7dbjHwqxixKqNM3om9XzWFrSpcL51NNfLD2\/image.png)\nQuarkChain ICO is basically in the same bracket as some of these other big ICOs as: Credits,<br> Ziliqa,<br> ICON,<br> WanChain... You can see these blockchain and infrastructure projects do extremely well in ICO and also when they hit the exchanges. These are the tokens that usually hold their value or even better 5X 10X even 100X themselves. So QuarkChain(QKC) token maybe the next very popular tokens. \n\n# IV. Team\nVery academic team,<br> their blockchain platforms built by math and research teams.\n![ (https:\/\/steemitimages.com\/DQmSaA9QrCh3zggpHdTJQ3QmadyEKaMHYQSJXp51VizW3rF\/image.png)\nQi Zhou is Founder and CEO of QuarkChain. He has software engineering experience with the likes of Google,<br> Facebook,<br> and EMC,<br> where he developed sharding and clustering solutions. Qi holds a PhD from Georgia Tech in Electrical and Computer Engineering.\nYaodong Yang is a Research Scientist with the QuarkChain ICO. He is the Cofounder of Demo++,<br> a startup incubator. He is also a Prof. at Xi\u2019an Jiaotong University and holds a PhD in Engineering from Virginia Tech.\n\n# V. Conclusion\nQuarkChain has very high hype points,<br> low hardcap and very high rating from many famous ICO reviewers ( Ian Balina,<br> CoinBlog). \nQuarckchain comes with a strong team and already has a working MVP and a public testnet. \nOnly several project get \"VERY HIGH INTEREST\" from IcoDrops.com\n![ (https:\/\/steemitimages.com\/DQmY9JfVvt6UqDDuHTEgghd74NTZaSj1tNCg1qdeW3Qn878\/image.png)\n\n# VI.
