# Glossary

#### **$AUKI**

A cryptographic and transferable representation of value secured on a blockchain, used to interact with the [posemesh](#posemesh) protocol. It can be burned for [credits](#credits) or used to stake a [reputation](#reputation).

#### Auki Labs

[Auki Labs](https://www.aukilabs.com) is a private company tasked by the [Foundation](#foundation) to develop the posemesh protocol.

#### **Burn**

The permanent removal of a [token](#usdauki) from the [total supply](#total-supply).

#### Calibrate

To calibrate a device is to make its [position](#position) or [pose](#pose) known within a coordinate system.

#### **Capabilities**

The [posemesh SDK](#posemesh-sdk) has modular extensions for the receiving and performing of [tasks](#tasks). To be able to register as capable of performing a task type, you must register that [capability](#capabilities).

#### **Credits**

A non-transferable representation of pre-paid claims on [posemesh](#posemesh) services and [data](#spatial-data). Credits are purchased through [burning](#burn) the[ $AUKI](#usdauki) token.

#### **Deflationary Mint**

The creation of new [tokens](#usdauki), in an amount less than the corresponding [burn](#burn).

#### **Demand Participant**

A [participant](#participant) requesting [capabilities](#capabilities) from the protocol in exchange for credits.

#### **Discovery Service**

The [posemesh](#posemesh) discovery service allows [participants](#participant) to form [domain clusters](#domain-cluster), and manages participant [reputations](#reputation) through a blockchain interface.

#### **Distributed hash table**

A distributed hash table (DHT) is a form of document replicated across several devices, so that each device has a full or partial copy of the data. The posemesh [discovery service](#discovery-service) uses a geographically partitioned DHT, meaning not all devices carry all data for all geographies.

#### **Domain**

A [posemesh](#posemesh) domain is a digital representation of a physical [environment](#environment) and a named coordinate system. [Participants](#participant) can load the domain into memory to gain an understanding of the environment.

#### **Domain Cluster**

A domain cluster is a collection of [participants](#participant) that exchange encryption keys with each other to perform collaborative spatial computing about a [domain](#domain).

#### **Domain Manager**

A domain manager is a special [participant](#participant) charged with the storing and serving of a [domain](#domain) and its [spatial data](#spatial-data) to other participants. It also coordinates workloads between the visiting participants.

#### **Domain Owner**

A domain owner is a wallet address on the blockchain that is registered as the owner of a [domain](#domain).

#### **Environment**

An environment is a physical space and its properties.

#### **Fifth Protocol**

A value exchange mechanism between software agents, as [proposed ](https://auki.gitbook.io/whitepaper/introduction/part-1-senseless-machines)by Naval Ravikant.

#### Foundation

The [Posemesh](#posemesh) Foundation is responsible for the issuance of the [$AUKI](#usdauki) token and the governance of the network economy. Their mandate is to create and promote an open source, universal spatial computing protocol and decentralized machine perception network.

#### **Position**

A position is a coordinate within a coordinate system.

#### **Pose**

A pose is a *position and rotation* within a coordinate system.

#### **Posemesh**

The[ posemesh](https://auki.gitbook.io/whitepaper/technical-overview) is a decentralized machine perception network and a collaborative spatial computing protocol. It is a mesh of machines reasoning about pose.

#### **Posemesh SDK**

The Posemesh SDK is a software development kit that allows devices and applications to connect to and interact with the [posemesh](#posemesh). It supports optional modules that grant [capabilities](#capabilities) to performed for yourself or other[ participants](#participant).

#### **Spatial Data**

Spatial data describes a physical [environment](#environment) using a named and persistent coordinate system. In the [posemesh](#posemesh) protocol, [domains](https://auki.gitbook.io/whitepaper/technical-overview/the-domain-service) store and serve spatial data.

#### **Participant**

A piece of software or hardware connected to the [posemesh](#posemesh) through the [posemesh SDK](#posemesh-sdk) is called a participant. Participants can join domain clusters and perform work according to their [capabilities](#capabilities).

#### **Tasks**

A task is a pre-defined message type within the [posemesh](#posemesh) protocol that allows a [participant](#participant) within a [domain cluster](#domain-cluster) to request work from other participants in the same cluster. Tasks are paid for in [credits](#credits) according to standardized units of measure for each [capability](#capabilities).

#### **Semantic Layer**

The semantic layer of the [domain](#domain) is a simple spatio-semantic representation of the physical environment, designed to be incredibly lightweight for the performance of basic tasks. It contains the [pose](#pose) of the domain's [portals](#portals), navigable areas and simple [semantically](#semantic) downsampled occlusion volumes.

#### **Topography Layer**

The topography layer of the [domain ](#domain)is a finer-grained polygon mesh describing the physical shapes of objects in the environment, to aid with [occlusion](#occlusion) and collisions. The topography layer provides finer detail than the [semantic layer](#semantic-layer), but is also a larger data structure that is more expensive to compute.

#### **Rendering Layer**

The rendering layer is a [domain's](#domain) richest and heaviest digital representation of the physical environment, complete with the textures necessary to render the space as a virtual reality environment. It is typically only used by remote [participants](#participant) that wish to simulate seeing the space.

#### **Partitions**

A partition is a volumetric subset of the [domain](#domain) data that can be accessed individually, so that [participants](#participant) don't have to download or update the whole domain at once.

#### **Observations**

An observation is something detected by a [posemesh](#posemesh) [participant](#participant), and is a subset of [spatial data ](#spatial-data)compatible with certain kinds of [capabilities](#capabilities). For example, where a recognizable feature appeared in an RGB frame at a certain time and place.

#### **Reputation**

A deposit of [tokens](#usdauki) locked into a smart contract allowing the protocol to penalize bad behavior.

#### **Supply Participant**

A [participant](#participant) making some of its [capabilities](#capabilities) available to other participants in exchange for token rewards from the protocol.

#### Substrate

The set of machines hosting a DePIN network, including the machines' resources not made available to the network.

#### Vacancy

A request filed with the [discovery service](#discovery-service) for a participant with certain [capabilities](#capabilities) to join a [domain cluster](#domain-cluster).

#### Organization

An organization is a wallet on the blockchain tied to an offchain [credit](#credits) balance with the [posemesh](#posemesh), and the ownership of applications, [portals](#portals), [domains](#domain), and [domain managers](#domain-manager).

#### Initial supply

The total amount of tokens minted at the creation of a network. In the case of the [posemesh](#posemesh), the initial supply is 10 billion tokens.

#### Total supply

The total amount in existence of a given token at a given moment.

#### Treasury

A treasury refers to a pool of [tokens](#usdauki) granted to the [Foundation](#foundation), to be used for network expansion and maintenance.

#### **Trustless**

An interaction governed by a smart contract ensuring good behavior from strangers.

#### **Utilization Rate**

How well a resource is being utilized. For example, how many nights an Airbnb is booked, or how many hours a GPU is working.

#### **Semantic**

Semantic information is data that describes the meaning of an object, such as "table, floor, wall". 

#### **Spatial**

Spatial information is related to a space, and has a [position](#position) or [pose](#pose) within a coordinate system. 

#### **Portals**

A portal is a unique QR code with known physical dimensions, remotely programmed to redirect and [calibrate](#calibrate) visitors and [participants](#participant) to a [domain](#domain).

#### **Occlusion**

Occlusion means hiding from view. In augmented reality, occlusion means which things should block other things from view. For example, you don't want certain things visible through walls.
