I presume for Qst
If a malicious miner wants to perform an attack on QuarkChain, it needs to collect at least hashpower of the whole network.*
the correct answer is:
(with 10 shards) - 5%
(with 100 shards) - 0.5%

This was for a specific scenario when hash power of root chain is 0%

[sw357]

can u break down in parts the answer to Q(What is the theoretical limit of the number of shards in QuarkChain?* )

[mrthomas]

Not correct, the root chain, which gets 50% of the hash power needs to be attacked. So for a 50% attack on the root chain you always need 25% hash power no matter how many shards are active.

[naga996]

I agree with you.

Exactly, question is not related just to some n-shards. It is related to Quarckchain which is 50/50 in two chains.
