Aigarth

Aigarth is a project focused on AI technology, aiming to solve artificial intelligence challenges by leveraging idle computing resources through the Qubic network. It runs a unique algorithm based on spiral logic gates, capable of evolving solutions in response to demand, and the process is publicly transparent. All participants can track progress and collectively drive the pursuit of efficient solutions.

Arbitrator

In Qubic’s dispute‑resolution mechanism, the arbitrator plays a critical role. It is dedicated to handling conflicts and safeguarding users’ rights within this self‑sufficient ecosystem. Its core responsibilities include setting miner algorithms, ranking compute nodes each epoch, replacing under‑performing nodes, and aggregating the $QUBIC that under‑performing nodes failed to receive.

Candidate

A candidate may become a compute node within each epoch, provided it ranks in the top 676 in scoring. Up to 256 candidates have the chance to achieve this promotion. Typically, only those who have run for a full week and performed exceptionally will receive $QUBIC as a reward. Candidates do not receive any $QUBIC, but working as a candidate is the first step toward pushing solutions onto the blockchain, a necessary condition for becoming a compute node.

Computor

A computor is a machine or node that participates in the network consensus protocol and executes computational tasks. It is a key component of the Qubic network, responsible for executing transactions and running smart contracts on Spectrum.

Computor Controlled Fund / CCF

The Computor Controlled Fund is a community‑centric funding system whose primary goal is to promote the growth and development of the Qubic ecosystem. It provides financial support for projects that enhance, expand, or improve the functionality, influence, and efficiency of the Qubic network. Projects are selected through community proposals and voting. CCF can rapidly integrate project plans and ensure efficient, orderly budget allocation. Its purpose is to co‑plan the community’s development path and ultimately give decision power to computors.

Key aspects of CCF include:

• Project Proposals: Any community member can submit proposals aimed at improving or expanding the Qubic ecosystem.
• Community Voting: Projects are selected and funded based on community engagement and consensus, ensuring that funds go to widely recognized and supported projects that align with community needs.
• Rapid Implementation: Once approved, funding is quickly deployed to realize proposals, fostering innovation and accelerating the ecosystem’s adaptive development.

Energy

The amount of QUs a given ID holds on Spectrum (analogous to a “balance”).

Epoch

During a one‑week period (starting at 12:00 UTC on Wednesday and ending at the same time a week later), 1 trillion $QUBIC are created. After a halving event, only 450 billion $QUBIC are in effective circulation each epoch.

Identity (ID)

Qubic’s wallet address, also the identity ID of a computor. In Qubic, miners are crucial to supporting computors: miners fetch problems or tasks from computors. When a solution for a given address ID is found, miners send the result back to the computor. This continuous exchange between tasks and solutions is key to determining each computor’s score within an epoch. A high score is essential for maintaining a top‑676 position.

Oracles

One of the features being developed on Qubic involves “oracles” from blockchain technology. These are third‑party services that allow smart contracts to receive external data and information. Thus, smart contracts can link the virtual world to real‑world conditions and execute actions that must adjust to reality.

$QUBIC

In the Qubic ecosystem, $QUBIC or QUs serve as the “energy” unit, used to run smart contracts and obtain other services. These units can be exchanged as a form of currency, but they also represent a resource investment—just as electricity powers a power grid, $QUBIC powers functionality in Qubic. Transfer operations are free and do not involve “fees” to the smart contract, because $QUBIC is consumed rather than compensated to the computor.

When interacting with oracles, a requester consumes a specific amount of $QUBIC as a form of investment or sacrifice, rather than directly paying the oracle. Therefore, we cannot guarantee that every query will receive a response; oracle replies are not deterministically guaranteed.

Quorum

A quorum is the minimum number of participants required to make decisions for various matters. In Qubic, the quorum required for consensus is two‑thirds of all computors (or 451 computors).

Quottery

Quottery is one of Qubic’s first smart contracts, enabling decentralized wagering with transparent payouts that make the process fair and predictable.

• 10 % goes to the Computor Controlled Fund
• 20 % is distributed to Quottery shareholders
• 70 % goes to the winning bettor

This marks the beginning of Qubic’s first oracle application, signifying an important milestone in technical practice.

Qx

Qx is the first decentralized exchange (DEX) in the Qubic ecosystem. In epoch 65, it completed an IPO (initial public offering) by selling a total of 676 shares to the community. Qx holders enjoy passive income from trading fees, thanks to the network’s ability to process up to 40 M transactions per second, providing a unique profit opportunity to shareholders.

Smart Contracts

Contracts whose terms are directly encoded in code and executed automatically. Qubic’s first smart contract is a decentralized exchange named Qx, which completed a 676‑share IPO.

Spectrum

Spectrum is a definitive and immutable ledger within the Qubic network that records every transaction that occurs inside the network each epoch. Using decentralized nodes to process its consensus validation, Spectrum emphasizes transparency, security, and decentralization, making it one of the key components of the Qubic network and providing trust and openness to users worldwide.

Ticks

In the Qubic ecosystem, ticks refer to the time interval during which transaction and smart contract calculations reach consensus. A tick may last only a very short time (less than one second).

Useful Proof of Work / UPoW

An innovative consensus mechanism is being explored that redirects computational power from energy‑intensive mining to tasks with tangible value, such as training AI models. Unlike traditional proof‑of‑work systems that waste energy solving complex puzzles, UPoW focuses on providing substantial help and meaning to society rather than merely squandering resources.
