UTXO Transaction Model
Inheriting Bitcoin's Unspent Transaction Output model, Qtum ensures secure and reliable transaction processing with improved scalability. The UTXO model provides better security against double-spending attacks and enables efficient parallel transaction validation.
Account Abstraction Layer
Qtum's innovative Account Abstraction Layer (AAL) bridges the gap between the UTXO model and account-based smart contracts. This layer acts as a translator between Bitcoin's UTXO and Ethereum's account model, enabling full smart contract functionality with the security of Bitcoin.
Proof-of-Stake Consensus
Qtum uses a Proof-of-Stake consensus mechanism that is significantly more energy-efficient than Proof-of-Work systems. PoS allows for faster transaction confirmations with block times averaging 32 seconds, and greatly reduces carbon footprint, making Qtum a more sustainable blockchain solution.
Decentralized Governance
The Decentralized Governance Protocol (DGP) allows Qtum to modify blockchain parameters without hard forks. This governance system enables community members and token holders to participate in important network decisions, proposals, and upgrades through voting mechanisms.
