For those of you who have not done the quiz for QuarkChain public sale, maybe this could help you score higher.

What is the official website of QuarkChain?

https://quarkchain.io/

During public sale stage, 1ETH = ? QKC.

31533 QKC / ETH

When is the planned date to launch mainnet 1.0?

2018 Q4

What does TPS mean in QuarkChain’s whitepaper?

Transactions per second

What is the main goal of QuarkChain?

Provide scalability and high throughput blockchain

Which are the main features of horizontal scalability in centralized world?

All of the above

What is the technology that QuarkChain uses to increase the throughput?

Sharding

QuarkChain’s scalability technology is mainly based on

Horizontal scalability

What is the consensus mechanism of QuarkChain?

POW

Which one is correct?

All above.

Will QuarkChain support smart contact?

It will support Turing complete smart contact written in Solidity.

If a user has his/her balance in shard A while the user wants to use a smart contract in shard B, what should the user do?

Have shard A directly access the smart contract.

If a malicious miner wants to perform an attack on QuarkChain (with 10 shards), it needs collect at least hashpower of the whole network.

25%

If a malicious miner wants to perform an attack on QuarkChain (with 100 shards), it needs collect at least hashpower of the whole network.

25%

Why users can make a cross-shard transaction on QuarkChain?

Rootchain can confirm it.

Based on QuarkChain's whitepaper, which one is correct?

It is reshardable after main-net launched.

QuarkChain Testnet 0.1 has been already running at:

2200 tps

According to Qi Zhou (our CEO)'s testnet demonstration (you can find this video on youtube), how many shards we have in that testnet?

8

According to Qi Zhou (our CEO)'s testnet demonstration (you can find this video on youtube), which statement related to "secondary" in a user's balance is correct?

It is the sum of all balances other than the primary account

According to Qi Zhou (our CEO)'s test-net demonstration (you can find this video on youtube), if one clicks the "Transfer Balance" button, what will happen?

Secondary balance will transfer to primary one.

Suppose current QuarkChain network supports A cross-shard transactions per second, how many cross-shard transactions per second can be supported after doubling the number of shards?

2*A

What is the theoretical limit of the number of shards in QuarkChain?

2147483648

What is a QuarkChain’s cluster?

All of above

When a user runs a QuarkChain node with cluster feature enabled and the node is running out of storage, what should the user do?

Both A and C

Which one is correct?

Root-chain first proof of work is the consensus mechanism for the shards.

(Optional) What kind of D-Apps (or blockchain applications) do you think need 10000+ TPS?

decentralized exchanges

Hope this helps guys. Cheers :)

감사합니다.
