Current Issues

Zilliqa beat Ethereum to the punch in releasing sharding. In Zilliqa's most recent test run they claim 2.5K TPS with 6 shards, 3,600 nodes on homogenous Amazon AWS EC2 instances. They even claim to have exhausted all of the available AWS instances in Singapore during their test. So what happens when the difficulty level increases and the nodes introduce varying qualities of hardware. Likely, TPS will decline. Zilliqa's latest results clearly show they are moving along in increasing TPS with an increased number of shards and nodes. Their test 7 months ago hit 1,400 TPS with 4 shards, 2,400 nodes).

Quarkchain Ideas

QuarkChain have set out to find a solution that balances both these needs through by separating the two main functions of the chain into separate layers.

• The first layer contains all minor blockchains, or shards, which process a sub-set of all transactions independently. As the number of shards increase, so to does the number of transactions which can be processed concurrently.

• The second layer of QuarkChain is the root chain. The primary function of the root chain is to confirm all blocks from the sharded chains, but does not process transactions itself.

QuarkChain allows for two types of transactions- in-shard and cross-shard. In-shard transactions occur between addresses on the same shard. However, 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.

Road map

• ​Q2 2018: TestNet 0.2 release which will support most of QuarkChain’s features such as smart contract, reshard, and so on

• Q4 2018: QuarkChain Core 1.0 release, Mainnet 1.0, and Smart Wallet (aiming for ~100,000 TPS at this time)

• Q2 2019: QuarkChain Core 2.0 release, Smart Wallet 2.0, (aiming for ~1 million TPS with clustering at this tim- e)

Team & Advisor

The team consists of 9 members, with the following being the key members of the team:

• Qi Zhou, Founder – PhD in Electric and Computer engineering with 5 years’ experience in engineering and software engineering with the most recent being with Facebook as a software engineer.

• Zhaoguang Wang, Software Engineer – 7 years’ experience in software engineering with tech giants such as Facebook, Instagram, and Google.

• Xiaoli Ma, Research Scientist – Professor at Georgia Institute of Technology. PhD in electrical engineering and 7 years’ experience in the tech industry with the most recent being the CTO of Ratrix Technologies.

• Yaodong Yang, Research Scientist – PhD in engineering, and a Tenure Track Professor at Xi'an Jiaotong University, and co-founder of Demo++ Technological Incubator.

They also have 6 advisors including Bill Moore, Chief Engineer for Storage at Sun Microsystems, Arun G. Phadke, Virginia Tech Professor, Zhiyun Qian, cyber security expert, among others.

QuarkChain ICO Opportunities

• Team is loaded with big name firms (Google, Facebook) and with PhD's in the relevant fields

• Scalability will be one of the main focus of blockchain in 2018, Should QuarkChain achieve such high-throughput, it could position the project amongst the few first-movers

• 20M$ Harcap is relative small which leaving huge upside potential (Zil market cap currently around 650M$)

QuarkChain ICO Risk

• Strong competitor in high-throughput scaling solution such as Zilliqa, Fusion

• No official partnerships established at time of the review. they could be more aggressive in terms of generating traction on adoption of the blockchain

Conclusion

With a hard cap of $20 million, high market awareness, and the private sale has been fully booked many times over, shortterm potential is very positive

Scalability is one of the key issues that stays in the way of mass adoption of the blockchain technology. With the exceptional team behind QuarkChain and the good result potential of their Testnet, Quark we believe Quarkchain could be the biggest winner of 2018.
