Qtum (QTUM) is the first smart contact platform to fully utilise proof-of-stake consensus. By building on top of the UTXO model, Qtum adds its own ‘Account Abstraction Layer’, allowing the UTXO-based blockchain to seamlessly interact with the Virtual Machine (VM). Qtum currently supports EVM, but will support multiple Virtual Machines in the future, including our x86 VM (in development).
Qtum provides endless possibilities for smart contracts and gives smart contact designers the stability and maturity of the bitcoin ecosystem. Qtum is the first blockchain to utilise a truly decentralised governance protocol (DGP), which uses smart contract technology to update blockchain parameters in a manner which is self-regulating, self-modifying, and self-aware.
