I saw some valueable questions under the same posting in the Chinese Board (Chinse version), I did the translate.
Someone asked:
Any investigations on Lisk sidechains?
I suggest to look at the following techniques:
1. To solve the scalability problem with a Layer 2 protocol. (e.g. Lightning Network, Cross-chain)
2. To implement Ethereum's Sharding - to avoid the seizing of transaction performance between contracts
3. A more expanded version of Lisk's design of sidechains
4. Achain's fork theory
Pros and cons? Who's better than others?
Very good question, hope to hear more here...
