Trade QTUM/USD

Bitcoin tracks balances using Unspent Transaction Outputs, each transaction consumes specific previous outputs and creates new ones, creating a clear chain of custody for funds. This model has well-understood security properties and makes parallel transaction validation easier than Ethereum’s account model. Ethereum uses accounts with balances, which is simpler for smart contract development but different from Bitcoin’s proven transaction structure. Qtum’s creators believed combining UTXO security with Ethereum’s programmability would produce a better platform than either alone, Qtum achieves this via its Account Abstraction Layer, which lets EVM-compatible contracts run on top of a UTXO base layer.

Qtum uses Mutualized Proof of Stake, where any wallet holding QTUM can stake by keeping the wallet open and connected to the network. Validators are selected to produce blocks proportionally to their stake, and successful block producers earn QTUM rewards. The minimum staking requirement is low, allowing small holders to participate. Unlike some PoS chains that require dedicated validator infrastructure, Qtum’s staking is designed to work from a standard desktop wallet, making participation accessible to a wide range of holders.

Yes. Qtum’s EVM compatibility means Solidity contracts compiled for Ethereum can be deployed on Qtum with minimal or no modification. The Account Abstraction Layer handles the translation between Qtum’s UTXO base layer and the account-based environment that EVM contracts expect. The design allows Ethereum developers to deploy on Qtum without learning a new language, and existing Ethereum tooling such as Remix can interact with Qtum nodes using its EVM-compatible interface.

No. QTUM/USD on StoicFX is a Contract for Difference. You trade QTUM’s price against the US dollar without holding any tokens. To stake QTUM, deploy smart contracts on the Qtum network, or participate in governance, you would need actual QTUM tokens in a Qtum-compatible wallet.
