What is Qtum (QTUM)?
Despite some general similarities, Bitcoin and Ethereum diverge in the specifics of how their blockchains operate and how they record and update balances held by users.
To keep its network in sync, Qtum uses a variation on proof-of-stake (PoS) consensus called mutualized proof-of-stake (MPoS).
Account Abstraction Layer
Qtum’s Account Abstraction Layer decouples applications from the underlying protocol, maintaining the performance of the blockchain and lending the ability to add more smart contract capability in the future.
Qtum’s Decentralized Governance Protocol (DGP) allows specific blockchain settings to be modified by making use of smart contracts.
Qtum Neutron &
ARM Virtual Machine
Qtum Neutron middleware and ARM Virtual Machine will support Rust programming language and other upgrades facilitating mainstream adoption of smart contract development.
