Review on Qtum by Huu Nghi

Qtum is an open source Blockchain application platform Proof of Stake (PoS) algorithm. Qtum's core technology incorporates a branch of the Bitcoin Core, the Account Abstraction Layer class that enables multiple virtual machines including Ethereum Virtual Machine (EVM) and Proof-of-Stake consensus to address industrial use cases. .

Pros
- For consortium blockchains, the consensus algorithm is usually called PoA (Proof of Authority). Instead of solving a difficult mathematical problem in PoW or holding a large amount of cryptocurrencies in PoS, in PoA, a list of authorized block miners is used to determine which nodes are allowed to create new blocks. The chain has to be signed by the majority of miners, then it becomes a permanent record. It is more efficient and secure since the miners are fewer and more reliable.
Cons
- Qtum probably has to find the scaling solutions for UTXO model by themselves but i believe in the team.
