Core Concepts Every Developer Should Know
Ticks & Epochs
Qubic finalises transactions in “ticks” (sub-second consensus events). Seven-day epochs group ticks and control reward distribution. This rhythm underpins all contract execution.
Computors
The 676 Computors are validator nodes. They secure the network, execute contracts and package the AI training tasks that power Qubic’s uPoW.
Feeless Execution & IPO Fuel
Smart contracts run without gas fees. Instead, each contract carries its own “fuel” from its Initial Public Offering (IPO) of QUBIC tokens. Users interact freely; the contract’s internal balance pays for execution.
uPoW & AIGarth
Useful Proof of Work means every miner trains the AIGarth neural network and execute other activities (such as mining Monero). Your dApps inherit security from the same compute layer that powers decentralised AI.
Oracles
External data enters Qubic through Oracle Machines. These are deterministic feeders of real-world information — essential for contracts needing off-chain data.
