Follow Up From Each Members, Discussion, Task Assignment and Junha's Comment

1. Byeongjee Kang: Tendermint + Stable leader format seems best now. However, it seems not much different from PBFT. PoA algorithms such as Aura does not have deterministic finality. Leaderless protocols such as HBBFT show much more complicated block proposal algorithm so not fit.

2. Jaehu Yeom: Brief Explanation on Tendermint-rs research task.

3. Seongjae Kwak: Deep dive into libp2p to see how peer discovery is done on code level - Distributed Hash Table.

• Reference: Ethereum Discovery V5.

4. Changhun Oh: Brief Explanation on Storage research task.

• Further Research on checkpoint is needed.

5. Yoonsuh Park: Research on Consensus Algorithms.

• Need another meeting for discussion focused on the consensus algorithm.

6. Taehoon Kim: Explanation on Merkle Tree and Merkle Patricia Tree. Implementing on MPT because Merkle Patricia Tree allows search per character("nibble").

• Further Research on Merkle Tree is needed. If efficiency is the reason why Ethereum uses MPT, we may use Merkle Tree. Also, research on other blockchains as well.
