QuarkChain is a blockchain that focuses on scalability, security, and decentralization. It uses a two-layered system with a sharded layer for distributing data across chains to allow high throughput and a root layer to confirm blocks. This structure is designed to handle millions of transactions per second and solve scalability limitations. QuarkChain also focuses on decentralization through game-theoretic mining incentives that align individual miners' benefits with the overall system. Additionally, varying rewards across chains ensures similar returns for solo and pooled miners, preventing centralization.

1. QuarkChain Solution to
Scalability, Security and
Decentralization (SSD)
QuarkChain is a user friendly and high capacity blockchain that focuses on scalability, security and
decentralization.
Scalability: Quarkchain uses a two-layered blockchain system: sharding layer, allowing high
throughput by distributing data effectively and a root layer, for confirming the blocks from the sharded
chains. This structure is designed to handle millions of transactions per sec and even solve the
limitations of blockchain scalability issue.
Decentralization: Quarkchain focuses on decentralization by using collaborative mining driven by
game-theoretic incentives which ensures that miners who mine for their own benefits, aligns with what
is best for the overall system. Also by offering different rewards and difficulty levels for each
blockchain, solo miners can expect similar returns as compared to a mining pool which results in anti
centralization. Also mining difficulty algorithm is designed in a way that the hash power is evenly
distributed among sharded chains and root chain.
Security: The 50% hash power allocation on the root chain of the network enhances security because
quark chain network is more decentralized than single block-chain system and so for a miner, it will be
very hard to collect 51% hash power in Quark chain network than that of single block-chain
Quark-chain definitely brings a suite of unique ideas to deals with the core problems that block-chain is
facing today.
