# Glossary

Key terms used throughout the OpenGPU documentation.

***

## A

**AI Agent** An autonomous program that acts on behalf of a participant (client or provider) to optimize decisions like bidding, pricing, and task attempts.

## C

**Client** A participant who publishes Sources and Tasks to the network, paying providers for computational work.

**Client App** Web application at [client.opengpu.network](https://client.opengpu.network) for publishing sources and tasks.

**Controller** Protocol contract handling access control and task publishing permissions.

## D

**Delivery Method** How task completion is determined: First Response (speed-based) or Manual Confirmation (price-based bidding).

## E

**Escrow** Payment held in the Vault protocol contract until task completion, protecting both clients and providers.

## F

**First Response** Delivery method where the first provider to submit a valid response wins the full task payment.

## M

**Management dApp** Web application at [management.opengpu.network](https://management.opengpu.network) for monitoring and account management.

**Manual Confirmation** Delivery method where providers bid with suggested payments and clients choose which response to confirm.

**Master** A wallet that controls provider operations without holding provider private keys (non-custodial).

## N

**Nexus** Core protocol contract orchestrating sources, tasks, and provider registration.

## O

**$OGPU** Native coin of OpenGPU Network used for payments, staking, gas, and governance.

**OpenGPU Applications** Tools connecting to the network: Client App, Provider Suite, SDK, Management dApp.

**OpenGPU Blockchain** L1 EVM-compatible chain handling settlement and security.

**OpenGPU Ecosystem** The complete system: Network + Applications + External products.

**OpenGPU Network** The infrastructure layer: Blockchain + Protocol.

**OpenGPU Protocol** Smart contracts and interfaces governing the task marketplace.

## P

**Provider** A participant who contributes GPU resources to execute tasks and earn $OGPU.

**Provider Suite** Desktop application for GPU owners to join the network as providers.

## R

**Relay** External product providing API-based AI services using OpenGPU as infrastructure. Docs at [docs.relaygpu.com](https://docs.relaygpu.com).

## S

**SDK** Python library for programmatic access to OpenGPU Network.

**Slashing** Penalty mechanism that reduces a provider's staked $OGPU for misbehavior.

**Source** An execution environment defined by Docker configuration, requirements, and constraints. Clients publish Sources; providers register for them.

**Staking** Locking $OGPU as collateral to participate in the network.

## T

**Task** A computational job published to a Source with payment and expiry time.

**Terminal** Protocol contract managing provider-master relationships and hardware registration.

## V

**Vault** Protocol contract handling payments, staking, and escrow.
