They employs a decentralized governance protocol allowing for blockchain parameters like the block size, block time, gas schedules, and the minimum gas price for contracts to be modified without requiring a fork. In my opinion, neither the DGP, nor the x86 Virtual Machine are such innovations as to make Ethereum users abandon ship and defect to Qtum. As Qtum is targeted at businesses, there has been some posts on line indicating that Qtum has already made business deals with two large companies. The first of which is the coffee conglomerate, Starbucks, though no details of what this partnership would entail are cited.

Pros

Qtum is a blockchain project based in Singapore that is aimed squarely at the face of big businesses. Read on as we go over some of the basics of Qtum, what it is, and what it’s trying to be. Qtum had somewhat of an odd start earlier this year. Initially, a series of Qtum tokens were released as ERC-20 tokens. These tokens, however, were not intended to be the final Qtum cryptocurrency.

Cons

Qtum's flaw is similar to many full decentralized blockchain like bitcoin, ethereum. it suffers from scaling issue. Qtum right now can do around 70 tps which is about 2 times as ETH can. this number is quite impressive but still not enough, however there're many scaling solutions in the work such as Lightning Network. moreover Qtum right now can scale with DGP by voting to increase blocksize and decrease blocktime but DGP also has a limit, it's not practical to increase blocksize to something like 1 GB to support more TPS.
