Quantum is the Ethereum system without the Ethereum blockchain — instead it uses the Bitcoin blockchain. ny existing smart contract running on Ethereum can, through QTUM, be easily deployed on the Bitcoin blockchain as well. So things like Lightning Network and Raiden Network, where applicable, both benefit the QTUM blockchain.
Pros
- Proof-of-stake validation is tried and trusted technology and the virtual machines on offer with the QTUM platform are an attractive proposition, this is an undisputed advantage of the Qtum Network. It is essentially the Ethereum Virtual Machine retooled to run on the Bitcoin blockchain.
Cons
- People get reewards in PoS to stake their coins based on the time they are being staked for, the longer you stake the larger will be your profit. This was a good improvement over PoW but it had a loophole, people who stake their coins can keep their node offline. Hence, saving the costs of maintaining an online node, online nodes were required to ensure a healthy network. They brought it online rarely to get a huge stake payout.
