For Ethereum's technology using the account model, in order to ease the integration of smart contracts, however, it must sacrifice efficiency. Qtum solved this problem by integrating a new layer based on Bitcoin Qtum Account Abstraction Layer (AAL) technology, which allowed it to integrate intelligent contracts, DApps.

Pros

DGP (Decentralized Governance Protocol) [2] is a technology used in Qtum, which allows blockchain parameters to be modified through a specially designed smart contract on the blockchain, without any disruption to the ecosystem like soft or hard forks.

Cons

Solidity is still in its development phase and many new bugs are discovered every other day. Be it the Short address attack or as in many crowdfunding scenarios, where the Ethereum affiliated Solidity smart contract was hacked because of security flaws resulting from a lack in the state of the art with respect to tools for formal verification.
