QuarkChain solves the common problem of efficiency and fairness

Few people realize that, without strong underlying technical support, the entire industry of the blockchain is still far away from the real boom in the application layer.

As a prerequisite for the development of the block chain, the common chain is the core guarantee for the future development of the block chain industry.

Underlying male chain not only build the block chain project "the underlying male chain industry application to solution," the development of logic, more props up the block chain project business application and operating efficiency of the upper expanding.

The urgency of developing the common chain is self-evident, and the expansion, high throughput and cross-chain of block chain have become the underlying technical problems that the block chain urgently needs to solve.

In dazzling block chain track, to find out the real potential and down-to-earth good projects, a key criterion is to see who can take the lead in based technology to solve these problems.

As a trade millions of times per second (TPS), high throughput block chain project, QuarkChain quark chain is a safe, decentralized, high capacity, extensible blocks the underlying technology scheme, it for the next generation public chain provides high scalability and high processing efficiency of technical service guarantee.

The vision of QuarkChain is to raise the current TPS thousands of times to tens of thousands of times, while maintaining security and decentralization, and pushing the blockchain into the next generation.

QuarkChain is building a network that is not congested, so everyone can afford to use the network, so it's natural for every industry that needs a higher TPS.

Ultimately, QuarkChain's goal is to create a seamless platform to support distributed social media, high-frequency trading, the Internet of things (IoT), gaming and financial payments.

But to really understand the value and significance of QuarkChain, we must also find out the historical context and future trend of the development of blockchain.

 Quarkchain's elastic split-layer technology -- the balance between efficiency and fairness 

 As the article begins, the expansion of block chain, high throughput and cross-chain have become the underlying technical problems that the block chain urgently needs to solve.Quarkchain wants to be a growth potential blockchain project, and must address these issues, and must find a balance between efficiency and fairness.First of all, from the point of view of network capacity expansion, the existing block chain network in transfer speed, a piece of time, high capacity, the system of concurrent, fault tolerance, stability, etc, will still be restricted.One way to solve the problem of scalability is independent to run multiple block chain (for example, COINS, Wright COINS, currency cash, etheric fang), so the increase in the number of chain blocks, the total capacity is increased.But doing so there are a few restrictions, if two blocks in chain using the same consensus algorithm, then calculate the force may not balance, and will make it easier to double flowers attacks, reverse trading and attack strategy of mining.Having multiple blockchains will also limit cross-chain transactions and further bring security issues.
 The root chain (also known as the main chain) on the second layer of QuarkChain is used to identify all the blocks from the split layer.The root chain does not deal with any transactions (because it is not economically efficient), and the root chain has sufficient computational support to ensure security.The QuarkChain block network is also designed to support the ability to dynamically add sharding.Add more fragmentation can easily and quickly, and users almost can't feel it (if add the shard before network congestion, users may feel deal faster). 

From the point of view of distributed storage, the small size of the block can easily lead to network congestion, so where should the large amount of block data be stored?

How do you store it?

How can high storage costs come down?

These problems greatly hinder decentralization and damage the core value of blockchain.

QuarkChain solves this problem by allowing multiple honest nodes in the cluster to run as full nodes.

Each node in the cluster validates only one subset.

As long as the combination of their subsets overrides the root chain and sharding, we can demonstrate that they can fully validate the entire block chain without the need for expensive supernodes.

In addition, if one of the nodes in the cluster to collapse, the rest of the node will still be able to fully validate any block, because any two of them form a cluster, so as to realize the high availability cluster.

In addition, in order to encourage the formation of such clusters in the network, QuarkChain answer will encourage node information about random block (for example, randomly chosen shard or root block random block hash of the chain of information as a problem).

Such a problem would encourage the nodes to store the entire network's books, and it would be inefficient to download random blocks from the network for short periods of time.

Finally, from the perspective of security, frequent hacker events have become a persistent shadow in the whole blockchain industry, and the security of the public chain itself is an urgent problem to be solved.

All transactions in the QuarkChain network are protected by 50% of the total net force, while the double attack requires at least 25% of the total net force.

This is less than 50% of the single block chain, but because QuarkChain is more dispersed, it is difficult for the malicious miners to get 25% of the total net force in the QuarkChain network.
