In today's world there are significant technical changes. It have become real, including through active introduction of blockchain technology. Thanks to it, there are new opportunities that until recently could seem unattainable. Existing business models have started to adapt actively to blockchain. First of all, this affected the most modern sectors of economics. System of smart contracts is confidently implemented in following sectors: medicine, logistics, investment, electronic payments. Despite convenience, blockchain technologies have a number of disadvantages. First of all, it concerns speed of operations, level of security. Therefore, developers of blockchain QuarkChain decided on creation of an entirely new transactional system. In it, the speed of operations will reach 1 million per second.

Features Of Quark Chain

Blockchain QuarkChain with maximum capacity will ensure decentralization and maximum data security. Still under development QuarkChain demonstrated to developers 2000 transactions per second. This figure is not final. However, already at this stage, excellent results have been demonstrated in comparison with other blockchains.

Scalability and security are two important factors that are not always present at the same time. In particular it concerns cases when we are talking about the blockchain. Developers of QuarkChain took decision due to which these needs are balanced. Experts plan to achieve this by dividing key chains into separate layers:

The first layer: combines small block chain (shards) that can handle multiple transactions independently from each other;
the second layer is root chain. Key function of the root chain is to fix operations. Transactions are not processed independently. Internal operations are performed only between addresses of the same chain.
Quark Chain blockchain is combined with Solidarity language, which is the most common programming language. It has been designed specifically for decentralized applications built by Ethereum (require high bandwidth). They will simply be ported to QuarkChain.

Positive features of QuarkChain blockchain

To achieve the result of 1 million transactions, developers of quark Chain will try:

to provide the highest level of security (based on joint mining): to ensure security of transactions and at least 50% of capacity will be located in root network to avoid possible attack;
to organize anticontraband horizontal scalability: blockchain QuarkChain will allow more available nodes to form the cluster. This will replace super-complete node;
to provide a simple and convenient account management: QuarkChain will attend only one account dedicated to all shards. Cryptocurrency listed from different shards will be stored in one smart wallet.
In future QuarkChain miners will provide economic incentives for enterprises in a super-node. They verify blocks inside root blockchain and all shards to prevent formation of the largest mining pools. Due to this feature, level of decentralization of used computing power will significantly increase.

QuarkChain ICO 

QKC tokens can be purchased during crowdsale. Cost: 1ETH will be 31533QKC. Hard Cap for this project is set in amount of $4 million. Users will be able to use QKC coins for transactions within the system. They will also be used for accrual of rewards to miners. Cost of QKC tokens will depend on active use of the service by users. If popularity of quark Chain grows, price of this cryptocurrency will increase.

It should be noted high professionalism of the QuarkChain team. All specialists have considerable experience in creation and implementation of software products.

Road map

According to the roadmap, next stage in development of the project will be a test for 10,000 transactions per second.


In my opinion, QuarkChain project is promising. After all, blockchain technologies are actively introduced in different areas of our lives. All useful information can be found on website or in official public on social networks. You can invest in purchase of QKC tokens to gain greater privileges. Of course, choice is yours! I recommend to follow the QuarkChain project carefully.
