What is QTUM?
QTUM, also known as Quantum Chain, is a blockchain platform designed to combine the advantages of Bitcoin and Ethereum. It was founded by Patrick Dai, Neil Mahi, and Jordan Earls in 2016 and launched its mainnet in September 2017. QTUM is the native cryptocurrency of this blockchain and is primarily used for transactions and paying network fees.
Technical Features
Qtum’s technology combines the Unspent Transaction Output (UTXO) model of Bitcoin with the smart contract capabilities of the Ethereum Virtual Machine (EVM).
- UTXO Model: Qtum utilizes the UTXO model from Bitcoin as the foundation of its transaction system, which helps enhance security, transparency, and privacy, and supports parallel transaction processing.
- Account Abstraction Layer (AAL): Qtum has introduced an Account Abstraction Layer to serve as a bridge between the UTXO model and the virtual machine layer, enabling the network to simultaneously implement updates from Bitcoin and Ethereum while supporting the execution of smart contracts.
- Mutual Proof-of-Stake (MPoS) Consensus Mechanism: Qtum employs the MPoS consensus mechanism, an evolved version of Proof-of-Stake (PoS), designed to enhance network security and incentivize participants. This mechanism defends against “spam contract” attacks by distributing block rewards among multiple validators and delaying a portion of the rewards.
- Decentralized Governance Protocol (DGP): Qtum’s DGP allows blockchain parameters to be modified via smart contracts without the need for a hard fork; community members and token holders can participate in important network decisions and upgrades through voting.
Uses of the QTUM Token
The QTUM token serves multiple purposes on the Qtum network:
- Paying Transaction Fees: Users must use QTUM to pay gas fees when conducting transactions and executing smart contracts on the Qtum network.
- Staking: QTUM holders can participate in the network’s consensus mechanism by staking their tokens, thereby helping to secure the network and earn rewards. Qtum also supports offline staking.
- Governance: QTUM holders have voting rights on the platform and can participate in decisions regarding its future direction.
Token Economics
The total supply of QTUM is 107.8 million, the majority of which is already in circulation. Qtum’s economic model uses a block reward mechanism to incentivize stakeholders, including newly minted QTUM tokens, transaction fees, and gas fees for smart contract execution. Block rewards were initially set at 4 QTUM per block and are halved approximately every four years; additional issuance is expected to cease by 2045.
